SYSTEMS OPERATIONS

8.1 Platform Cooper

By day we used standard procedure of finding a zero yaw, which is a little easier to do down at about retro position.

The nose is a little bit

in the way for determining zero yaw unless you pitch down just a little past nose low in zero zero- zero position.

When pitched down just a tiny

bit, zero yaw was very readily apparent to within a fairly reasonable degree of accuracy, and then ease it right on up .

We had lines for the zero

zero position to give us our pitch and roll on the horizon.

This was the regular day alinement.

Night was pretty much the same except we 1 d get zero yaw by a star, get roll and pitch by the zero lines on the window (or knowing where they were approximately) line this with the top of the air glow or the horizon.

At that point you’d go into

Cage, hold it there at that position until it caged) then uncage the platform to BEF or SEF whichever the case might be, and then to to Plat form and Attitude on the FDM and FDI’s.

Then

aline the platform fine aline SEF or BEF by keeping

the needles zeroed.

It would slowly gyro torque

itself and correct out the small errors for fine alinement. Conrad

Anything to add, Pete?

Well, I didn ’ t hear all of that, but I think the alinement is straightforward.

One thlng I had not

read in either the GT- 3 or GT- 4 debriefings on this subject on out the window alinement was that we have a window gage that you can us1i t hat will put you right on in roll and pitch ancl, of course, for yaw you still have to use the same out the window reference. Cooper

One thing that I think that should very definitely training wise be readily available anc. we looked and looked and looked and couldn’t fir..d any was an actual scale picture of the left hand wi ndow and the right hand window with what the hcri zon should look like at zero-zero-zero and at retro attitude and at minus 90 degrees left and 90 degrees r ight and at 60 degrees left and 60 degrees r ight and this type thing .

I’ve never seen an a~tual drawing

showing the horizon line on a window a·‘ld what i t should look l ike .

3 Conrad

Yes

Cooper

I think this would be a tremendous benefit and shouldn’t be difficult to come up with.

Conrad

If you place your eye so that it goes through the lower left corner of the right window or the lower right corner of the left window and run that eye position right through the front RCS yaw thruster, the lower yaw thruster in the front ring, I guess that’s ring A, anyway, you take a line between your eye, the corner of the window and the front RCS yaw thruster, right through the middle of it, and put that line on the top of the airglow or the horizon.

Then the spacecraft, and this looks like

an excessively nose up attitude, but it’s not, you’re zero degrees in pitch then the window frame is just about vertical to the horizon and it forms a perpendicular angle. Cooper

The inside edge of the frame .

Conrad

The inside up and down edge of the window corner makes a perpendicular angle to the horizon and you can use that as a roll gage.

If you set it up

that way that platform isn ’ t off 4 or 5 degrees i n roll or pitch. Cooper

So, i t r eally looks like, when you fir3t start lining it up, it appear s to you that f ::-om the left seat that you ’ re actually rolled l eft ,

Conrad

Yes, that’s right .

Cooper

And f r om your seat it would look l i ke j t was actuall y r olled right .

Cooper

It doesn ’ t look horizontal at al l, but that ’ s due to the fact t ha t you ‘re sitting off by thi s offset .

Conrad

One other thing that you might say about platform alinement is that if you ’ re not on in roll and pi tch, mainl y roll, t his really will ea t you up in alinement time .

Cooper

Roll and yaw are t he bad errors creator:, .

Pitch

you can be off a l ot i n and it’ 11 corr ec:t r ight out. Conrad

Not if the other two (roll and yaw) are off .

Cooper

But if you ‘re off in roll and/or yaw th€n it really takes a long time and its real rcugh .

Conrad

You don’t want to be deceived by the fact that the needles are holding in the center pretty well.

Cooper

That’s right, one thing that we found when we were going through this real, real long platform alinement prior to getting all l i ned up for retro fire was that we had the needles all alined, t hey were sitting all glued out .

But you have to s i t

there with them for a little b i t glued out .

They

sit there all zeroed out, it looks like everything was all alined and al l of a sudden yaw begin to ease off quite a bit showing that we weren ’ t alined. Conrad

At one time we went to Orbit Rate when we had not pulled the yaw all the way in and, boy, it showed up in r oll as we started moving around.

Cooper

Orbit Rate and Horizon Scan.

Conrad

I mean it shwed up in the roll axis .

Cooper

Oh, yes.

Conrad

You have to take t he time and be careful with the

Right .

platform alinement, no doubt about i t.

° CSf*fDEt◄ TIAl

Cooper

And i t takes t ime to do it and do a r ~ally good job on it . Modes .

The only thing I can say about Cage is

that it takes an excessively long tim1; to Cage . Conrad

I ’ ll comment on this even though we d:i. dn’t get a chance to do the rendezvous , but even in simula tion, it was apparent and the l i ttl e bit t hat we did in flight caging the ~latform, getting ready for alinements and t hings l ike -;hat, it was very time consuming .

I think tha ·; you could

find use for a f ast slave cycle . Cooper

Very much so.

Conrad

Fast Cage cycle is what I should say.

I ‘ll say

it’s a luxury item but it sure could be helpful . Cooper

SEF and BEF worked j ust like advertisEid .

SEF

for fine aline and small- end- forward, BEF for reYersing your phase angles so that you ’ re still steering to and fine alining blunt encl forward . Conrad

J i m and Ed made the comment that t hey never alined BEF, that t hey a lways alined SEF.

We alined SEF

normally through the flight and when ,:e were ready

60 ►◄~ ~

7 to retro, we wanted to save as much fuel as possible, so we alined BEF and I think alining BEF is easier than in SEF. Cooper

Yes ,

Conrad

I think you can tell yaw better going backwards than you can going forward.

Cooper

Yes.

Conrad

I don’t know why, maybe it was just psychological .

Cooper

I agree with you, I really think you’re right. I think you can tell it better.

It streams away

from you a little more . Conrad

Yes.

It was easier to pull in in yaw .

I thought

it was a little more comfortable feeling .

enjoyed the riding around alining the platform BEF much more than when we alined it SEF, and I felt we were closer to being on most of the time when we pulled it in in yaw. Cooper

Of course, we had a little better control system there, it does help.

Conrad

Yes .

~NftDE~~TIAt·,_

8 Cooper

I think either way (SEF, BEF) is good, both worked very a dequately and it just depends on which way you want to aline for what you ’ re going to do . BEF is certainl y a t least as acceptable as SEF. ORBIT RATE was not bad off a t all .

We di dn’t

have any l arge errors in it due to t he f a ct that we had more nearly circulari zed our oroit from t he burns that we did . Conrad

We were about at 171- 60 at that time p⇐:riod .

don’t know what t hey ha d picked as an orbit rate number at the end fina lly for the REP . Cooper

We were about 107, 166 .

Conrad

Yes .

I was really surprised with how ,..,ell the

platform stayed on after just t a king a quick look at zero- zero- zero, not even trying to ali ne these. We j u st passed freely through this in dr ifting flight and uncaged the platform right into Or bit Rate, and it didn’t get off five or ten degrees in any of the three axis . Cooper

For about 20 hours .

‘i0 ►~~FIDE►~~TIAL

G©t◄ FIDl!~~TIAL Conrad

Yes, for about 20 hours that we drifted around . It was finally off the most in roll.

It got about

15 degrees off in roll . Cooper

Orbit Rate worked very well .

Conrad

Other than inertial work, I just didn’t see any big advantage in free.

You’d still think in

terms of the local horizon up there most of the time. Cooper

Yes .

Conrad

We just never had much occasion during the f light to use FREE.

Cooper

Platform displays .

Conrad

Bal l oper ation through the poles was just fantastic!

It was so smooth.

The only way you

could tell that you were going through a pole is you could see the roll index, vehicle is on the

roll gimbal, flip . Cooper

Yes.

This is something we had trouble finding

out, whether this was the case or not and we deliberately ran several specific checks of this.

Et.~TIA ~

But I ’ m still

COt—1 FID Et◄ :r IA~

convinced that because we went so long with the OAMS heater off that we were not burning a nominal fuel to oxidizer ratio. Cooper

Yes .

Even though we were in a

rush to get a lot of …

these things done, I was still extremelr conscious of fuel usage .

Although I’d used Direct to get

i t started, I wouldn’t just fire all the way around in Direct input, let it coast around, a~d then stop it right there. Conrad

Yes.

I never saw fuel usage in the sim1lator like

we saw in flight . Cooper

I t just seemed to go down very rapidly on the gauge during that one period of time.

Conr ad

And yet we went night after night all night long in Horizon Scan or in Pulse and would hardly use any fuel at all .

As a matter of fact, the ground gave

me the figures.

Thi s was when we were ::unning all

ni ght long in Horizon Scan so that we had a nice reference . a night.

They said “You’ re using about 2 pounds Now, that seems like a r easonable amount

for what we were doing.

•

Cooper

We were using it for Attitude Hold and for getting pictures and to get through the day side .

Conrad

Oh Yes.

We never used Rate Command except for the

maneuver burns. Cooper

We were tracking the missile using Diredt.

Had to

get on it in a rush so I went to Direct . Conrad

I questioned propellant quantity prior to lift- off. It was 87 percent at lift- off,

I thought we were

supposed to be 100 percent on the gage at lift- off . I thought we had propellant quantity loaded to the

maximum? Cooper

Well, they said we were about 50 pounds under .

Conrad

Yes, they said we had about 50 pounds less fuel than we were supposed to have.

Cooper

We asked them about this before we l ifted off,

Cooper

At about 4 or 5 minutes before lift- off, we asked them about this.

Conrad

We got a “We ’ re checking” and that’s the last we heard from it.

And off we went .

28 Cooper

So then we asked again when we wer e in orbit, “About this under load on GA.MS fuel” .

I su spect

t hat something was fouled up because we didn ’ t get a full 0AMS load . Cooper

That was pretty bad .

I think monitor ing onboard of propell~mt r emaining t o compl et e the mission was pretty good.

The fore

cast fuel for mis si on completion of GE,m ini V ought to be reviewed because somebody didn ’ t quite come up with the right fuel figures .

Twenty- six percent

remaining after the REP would not havE been nearly enough to have ~one the r emainder of the mission . Conrad

Yes .

I t hi nk t hat in computing the a.mount of fuel

used t o perform a maneuver, they figure out how much to get the r ates going but they must s top there . They must not f i gur e how much fuel it takes you to . get back to, say, zer o- zero- zero .

Appirentl y t hey

assume that whenever you get done with a tracking maneuver, you j ust drift to get back to zero- zero zero.

Over the U. S . we had maybe 6 or 7 minutes be

t ween a 30 degree pitch- down target to the next 30 degr ee pitch- down target .

You ’ ve got to t r ack

it all t he way through, bing the spacecraft all the way back up and then go to and track the next target .

Cooper

And stop your rate at the back .

Conrad

As a matter of fact, that’s about twice the fuel usage . it.

Cooper

They may take this into account, I doubt

They’re very conservative on their estimates .

Selector controls and switches were all right . Attitude controller was fine . (

Maneuver controllers .

We had every intention of checking the right one and we never did check it because of other problems . Inflight malfunction irregularities we’ve already covered pretty well . Cooper

Attitude Control Modes, Rate Command was excellent . Reentry Rate Command we never checked .

Conrad

I don’t even think you need it .

Cooper

And I think it could be removed from the spacecraft as far as I ’ m concerned . the simulator .

Conrad

I never used or need it on

I never liked it.

Pilots aren’t going to tolerate these higher r ates . They will damp before these rates are reached.

Cooper

Direct is a good mode. wrong with Direct .

There ’ s nothing at all

I thought it was much crisper,

much crisper in the spacecraft than in the simulator

shows that it is .

The Pulse mode was very economical

on fuel and I felt that in the sinru.latc,r you had a little more authority than you actually did in the spacecraft .

The spacecraft had slightly less

authority in Pulse than the sinru.lator does .

Inci

dentally, you can use Pulse just for a month of Sundays and never see the fuel go down on the 0AMS gage at all.

You can use Pulse all day long with

using little fuel usage .

Horizon s can, the primary

Scanner was inoperative as was stated e3.Tlier . Secondary Scanner worked fine.

The

The sca::m ers, I

think, operated quite satisfactorily.

We had a lot

of scanner dropout in the primary and eiren in the secondary.

We had some dropout in the :iecondary

when we first were going in and out of i;unlight areas . Conrad

But then it seemed to work allright .

Cooper

Horizon Scan Control Mode worked fine .

Conrad

It’s a loose mode but it still works fir..e .

Cooper

It’s got wide limits on it of course, -which i s okay .

The mode itself works fine.

Real good.

There was s ome

The platform mode

is supposed to be plus or minus 5/loth of a degree .

it was plus or minus 10 degrees I ’ ll eat my hat .

•

31 Conrad

I thought it held to about a degree and a half .

Cooper

Not in yaw , you remember .

It allowed yaw to wander

off by probably a good 10 degrees there.

Remember

it allowed right yaw to wander off by about 10 degrees and just sit off there in right yaw several times. It wouldn’t even bring it back. Conrad

Yes .

It may have been that con

I don ’ t

But Rate Command sure

worked good using those same controls. Conrad

Yes .

I suspect that being the first time that it

was cranked up since spacecraft number 2 , it may not have been tweeked as well as it could have been. Conrad

It certainly didn’t work like it did on the simulator , I ’ ll put it that way.

Cooper

It didnlt work properly, and it was no good the way it was.

We never used it after we originally tried

it out and after we 1 d tried doing this one burn on it to see if it would hold.

The one that it did hold

on, our first perigee adjust, it held beautifully. During the next one, it got so bad it wasn I t any

32 good .

Ther e again , it might have been a f unction of

the thrusters going out . In any event , I think that 1 s an error ,;hat somebody needs to look i nto .

I ’ m n ot sure that pl atfor m mode

is doing what i t should.

I know that , t heoretically ,

and by t he diagrams on it and the limit s that it ought to be a ver y pr ecise control modE! . Cooper

Spacecraft separation at SECO + 20 couldn ’ t have been better , jus t fine .

Translat i on per igeE! adjust went

like cl ockwork. Conrad

Tha t was our fi r st r eal burn and I thi r.k we got something like 9 . 6 f t/sec on t he IVI ir.stead of 10 . 0 , but t he burn wasn ’ t that crit icaJ .

Conrad

I checked accelerometer bias and it seE•med like the accel er ometer bias incr eased l a t er in the f light . I specif icall y checked it f or the REP end it was okay .

I 1 d just set up zer os in the wirdow and

went to Catch-Up and they stayed zero for 3 or

4 minutes or longer .

So that satisfied me .

That can

In the beginning it was

entirely acceptable for the REP .

•

33 Cooper

I think we had some bias, just how much I don ’ t lmow. The timing of the translation was fine , updating was fine.

Operations and checklist were okay.

Computer

usage, okay. Conrad

It was easier to make a burn on the simulator that had no up- down or left and right in it than it was in the spacecraft .

Gordo did a real good job of

tracking on every burn and I didn’t see it wander hardly at all . Cooper

And all the IVI ’ s would be zero .

Conrad

And all the IVI 1 s would be zero, but we’d have .4. of 10 a foot in one axis and ~O in another.

Conrad

Yes .

The worst cross- coupling, we had 10 in one

axis, and when we burned in the platform mode, but we were checking that .

It could have been accelero

meter bias again, or, the spacecraft is more sensi- • tive to picking up up- down and l eft - right velocities than I thought it was . Conrad

Gordo did a real good job of tracking.

He tracked

as well as he did in the simulator and we never had this show up in another axis in the simulator . Cooper

It would be zero , zero , zero in the simulator.

Conrad

It was hardly worth my time checking address 81 and 82 in the simulator because I could just tell he

34 wasn’t going to have any velocities in there , and very seldom did .

But we never fail ed t o have fairly

si zeable ones , like

fa and fo fps, in another axis

and I’m not quite sure how it got therE·.

I guess

the spacecraft is extremely sensitive .

If you ’ re

going to make pr ecise burns , you I ve gotta really burn precisely and i f you want to take out the errors , take out the addre ss 81 and 82 errors so that you don ’ t introduce anything else .

During the difficult ren-

dezvous maneuvers, you have to plan on more f uel usage because you’re going to have to take it out with the up- down thrusters . Cooper

I think what you ’ re going to have to do is stop short of burning off all your forward or aft velocity, particularly the forward velocity, and then use the canted thrusters to burn off the right- Left and up- do,m and that will take out part of the remaLnder of the forward velocity.

If it hasn ’ t taken it all out ,

then bleep out the rest of the f orward .

I think

that 1s the only way you can do it if you want to burn them a l l t o zeros.

I don ’ t believe you can t r ack

any more precisely if you keep all your IVI ’ s zeroed right down the money.

If you burn it off and stop

just at the right time so that everything should turn

;CO tsifH0E1t~I IAL • d up wi· th .1_ , 2-, or up zero , then youst i·11 win 10 10

6 in all your windows. 10

I just don t t know how you I re

ever going to do any better than that .

(Unless you

use the above procedure). Cooper

Translation REP deployment was passable .

FCSD Rep

This one you didn ’ t .

You didn ’ t fire back at the REP

after jettison? Cooper

No.

FCSD Rep

Let’s replace this maneuver with the simulated opera tion (phantom rendezvous).

Cooper

We did deploy the REP and the radar did operate properly.

FCSD Rep

Originally when the debriefing guide was made out, this section covered the translation back after REP deployment and the subsequent translations .

Cooper

Okay .

FCSD Rep

We ’ ll just have to use the translations that they made on the simulated run .

Cooper

We kicked the REP out at 90 degrees right yaw .

Conrad

We kicked it out at 02 07 + 15, or 15 seconds l ate .

Cooper

The reason we were 15 seconds late , as we stated earlier, was that going into the night side the night before , after all our careful platform alinements , all of a sudden the horizon scanner began to drop

out on us and we began to drift off in yaw. Conrad

Dropping out wouldn’t have been bad, but when it dropped out it also commanded some thrusting.

Cooper

We got some real good blips out of it .

Conrad

We were alining i n the Horizon Scan Mode and I got the impression that it pitched us up .

Cooper

We wer e already alined , and we had gone to Orbital Rate and Horizon Scan, just to come alcng there in time to go in .

As soon as we had the Ilatform all

al i ned , and before we went in on the night side , I decided I would realine the pl atform ji.:st very briefly .

So I had gone to SEF and to IULSE and I

was checking and pulsing it . • But becai.:.se t hen in SEF position all your torquing is done f rom your Horizon Scanner.

When t he Horizon Scar,ner began to

drop out we began to get real erratic needle display and it looked like our platform alinemEmt was deter iorating.

I was trying to correct thiB , but

obviously, it was really kicking us off .

That was

when we went t o CAGE , tried desperatelr to get it caged and realined in time , and thought we had i t realined .

We may have had it reasonab:.y well alined

by the time we f inally yawed right . it was .

I ·; looked like

The needles wer e all zeroed out and

everything was settled down . .was working at that point .

The Horizon Scanner It quit working properly

after we turned to yaw right .

We had already gone

into Orbital Rate, so we could care less about the scanner at this point . already in Orbital Rate .

We got it alined, and we ’ re We yawed right , got squared

away and 15 seconds late ejected the REP on the IVI’s all zeroed .

We then used a couple of DIRECT

pulses , zipped back around , picked it up going around to the 270.

It was going right straight out to 270

on our ball .

We could see the REP light whenever we

were passing through the 90 degree point . I could see it flashing on the nose .

On my side,

By the time we

got around it was in quite close, we could see it going out with a very slow tumble rate, flashing . FCSD Rep

What would you estimate the tumble rate to be?

Cooper

It was tumbling very slowly, I would say maybe a half to 1 degree per second .

Conrad

I 1 d say a degree per second.

Conrad

I couldn’t tell what it was in roll .

It didn’t seem

to be tumbling in more than 2 axes . Cooper

That was ha.rd to tell .

Conrad

When I saw it , you could see the dipole come around . We couldn 1 t tell anything about roll, but it was not

tumbling in the other axes.

The blanket was sitting

_r ight next to it . Cooper

The blanket went out and was sitting ri1sht by it. went right on out with it . it .

That was thi~ funny part of

The blanket was between the REP and us .

Conrad

Yes.

Cooper

The blanket goes out first.

The REP ha:3 a lot more

mementum , apparently the REP had gone b;r the blanket: Apparently it had either hit it or moved it over or something because the blanket was betwe,m us and the REP . Conrad

Yes.

I don ’ t know exactly what happenecl there .

Cooper

It was just a few feet outside of the REP .

The REP

went straight on out to 270 , radar was working fine , r eading out everything just right , lock1~d on, and went out to the point where it should have s·~arted s l owing down . Conrad

This is where I had a mistake in the fl:.ght plan and didn’t catch it .

The computer was in PHELAUNCH and I

was wondering why I couldn’t get any digital readout . I t took me a few seconds to catch on to that one and I realized that I had to get the computEir into CATCH- UP.

We had never run into this problem where

we’d gone through a complete insertion checklist

39 which calls for putting the computer to CATCH- UP. I had gone through and zeroed 25 , 26, and 27, talcing the ascent routine numbers out of it .

So that I knew

that we were getting the right readings .

I had put

the computer back in PRELAUNCH, also had this discus sion at that time and that ’ s when I didn’t blow the cold IR doors until the REP was out . Cooper

I’ve said it before, and I also said it after my Mercury flight ; that is , “If you continually shove things in on people very early in the flight, the quality of it is going to be degraded.”

You need the

first two or three orbits to check the systems over, to get oriented , learn how to aline the platform, to learn how to use the systems , to learn where things are, to do these things before you start giving -p eople complicated tasks .

You just aren ’ t going to

get the quality out of them unless they’re flying exactly the same vehicle for the second or third time and they 1 re very experienced in it and they ‘re familiar with everything that ‘s onboard and there ’ s no change in equipment , no change in control system, no change in any of these things .

Then , perhaps they

could leap right off and go right into the first orbit and do these things .

iottf

But to put somebody into

•

a strange vehicle, with strange control systems tha t you’ve only simulated as about best you can , and no visual simulation available for doing anything out the- window ; you just cannot expect people to stay right on top of things when it occurs ir. the firs t part of the flight .

This is an ideal eYample ; we

had worked and worked and worked and worked and worked to have our timing down just rigl:.t.

If noth

ing had happened , we would have had our timing down just right and everything would have gor..e just per fect .

Pete would have been right on hi~ checklist

and blown the cold IR doors right on tirre. Cooper

I I d have been right exactly on time on g·etting the REP out and everything would have gone reach- keen . Just that one thi ng , the Hori zon Scanner failure , really threw the skids to the thing and caused us to be running s l ightl y late .

There was added con

fusion in trying to f igure out how to get t hings going and salvage the whole thing really threw the skids to it . Cooper

The REP went out and it continued going out instead of slowing down as it should.

It cont i nued to move

on out at quite a separation r ate .

The thing that

still has us a little puzzled , instead of slowing

41 down and coming to a null out there , it appeared to s t art moving s omewhat at the same separation rate to the south of us slightly towards a trail position very slowly.

We tracked it f or a long t ime .

We were track

ing it straight out and then all nf a sudden , it began to loop around slightly to the lef t . 1

Conrad

It di d something like I d never seen before!

Cooper

I d never seen this happen in the simulator, and

it still doesn ’ t seem quite f easi ble to us that this could ever happen . Conrad

One pos sible answer, and it ’ s r elated to something that we saw later in the flight , Gordo , where we alined the platform and had -yaw error couple into roll .

Might not this have given us bad steering in

formation as far as our radar needles were concerned if the scanner wasn ’ t working properly? We didn ’ t have the platform alined right .

We went along

30 minutes , almost one- third of an orbit .

I f we

di dn ’ t have an alined platform, that would start coupling up in some other axis like roll and we woul d be off in yaw .

Then when we thought we were

pointing at the pole , we reall y weren’t.

Maybe it

didn 1 t reall y drift behind us , maybe it stayed out on our wing.

We must have put it out fairly well

out of plane , in that it hung around us so darned long. Cooper

It stayed with us for 20 orbits !

Conr ad

We saw it until the light burned out . f ar away from us .

I t was never

During five night cyc les it was

close enough that the flashing light illuminated the spacecraft .

At the proper times, when we would get

nodal crossing, when we turned around and actually s aw the REP it was very close . Cooper

We t hought we were going t o hit i t .

Conrad

It was bright enough t o illuminate the spacecraft and the flashing light r eally impress ed me .

FCSD Rep

Did you take pictures?

Conrad

Ye s , I think we have some 70- mm Hassel blad pictures and I took 16- mm moving pic tur es .

Cooper

That was the last of the REP exercise .

Conrad

I understand all t he movie film came out, too.

you ’ ll have pictures of it . Cooper

At this point , we wer e rapidly running out of cryo genic fuel cell oxygen.

We decided t hio.t the only way

we were going t o salvage the f l i ght waE to stop using it at this rapid a rate .

We had to make the

choice whether we were going to power down and con t i nue the f light , or whether we were gcing to end the flight very abruptly if i t continuEd going down

we@t.tf 1!9 l!l’it~~.

43 at this rate . Cooper

We had a short discussion on t his and decided that we ’ d better power down and forget the REP because we were in trouble .

Cooper

So we tearful ly decided to give up the REP and power down .

Houston agreed with us when we got in touch with

them that we had done the right thing. REP.

That ended the

We did see it for quite a few orbits later .

Then Houston came up with the simulated Agena ren dezvous exercise , which they put on one of their computers .

The three burns they gave us to do went

off very satisfactorily, the thrusters worked very well .

They would not allow us to use anything but the

aft firing thrusters because they wanted to keep the cryogenic oxygen in the right position in the cryo tanks .

Apparently the burns went to their satisf ac-·

tion too .

They seemed to feel that it put us right

where we should be . Cooper

We tried one of these burns with the Platform Mode . It did not work satisfactorily so I used Rate Command which worked very well .

Conrad

1 We t ried to take the errors out and thats where we got

fo error left and right and a fo error up and down , so Gordo fired off the fo into trouble .

We had about a

tG~~FIDE► ,•♦♦ L.

44 left and r ight .

We wound up wi tr. too much going

forward and we s tarted to back up and suddenly we remembered we couldn’t back up s o then we decided well , we ‘d j ust leave thEi errors on the burn and burn i t the best we could because no matter what happened He’re going to translate i nto forward and what we should have done and we didn’t think of i t at the time—but you learn—we shouldn ’ t have burned all the forward—we should have burned down to about a foot of what we were supposed to have forward ancl then taken out the left , right , up and down and go ahead and burn the forward again. FCSD rep

The updates that they sent you on—

Conrad

That worked fine.

There was no problem.

We copied the numbers down , entered the computer.

We had plenty

the maneuver.

We btuned r ight on the cl ock

as advertised and we seemed to have gotten approximately i n the positi on they wanted us to get to . FCSD rep

What burns did you s i mulate?

Conrad

Well, we did a— I ’ ve got them r ight here.

@oM~lA

co~~r,ocr~r,At , Cooper

We did a separation burn and we did a cl osing burn and a coelliptic burn .

Those the ones

we did , Pete? Conr ad

Well , i t was—

Cooper

We did not a standard coelliptic—it was

a-Conr ad

No , we did a maneuver burn , which as—wait a minute—we did an apogee adjust maneuver which was a retrograde of 20.1 feet , then we did a phase adjust maneuver which was a forwar d burn of 15 feet .

No .

Cooper

Yeah.

Conrad

15 . 8 feet , then we did an out- of- plane burn , yawed left 900 of 15 feet and then we did a reverse coelliptic burn- -

Conrad

We burned- let’s see—we burned 16 . 4 feet forward and we di d four burns altogether.

FCSD r ep

Aft thruster s for all?

Conrad

Aft thrusters for all- -on out- of- plane- and that was the only t ime that we did ever , ever f l y the translat ional l eft , right , up, down thrusters.

We used them

to take out some of the IVI readings there

a couple of times.

And they were very

straight forward—left, right , up, down . Cooper

We even fired the forward-one quick l ittle blip .

Conrad

We fired the forward one then we suddenly remembered we weren’t supposed to .

FCSD rep

What kind of visual out- the -window did you see on these translations?

In other

words-Cooper

Left/right lights things up real w?ll- I could see the glow from the aft—they were- -

Conrad

J. B. is referring to visual cues )n the horizon and we were on the gages—

Cooper

They were at night—middle of the night- everything we did was in the middl 1~ of the night—this spacecraft only ran in t he middle of the night (laughter) .

Conrad

I really don’t remember making a burn-

Cooper

We never did anything in the day—

Conrad

Yeah , I think one or two of them were on the day side—but by and large—

Cooper

I never did so much night work in rzy- life—

EONFIDEt~ AL,.

COt~FIDE~~TIAt FCSD rep

OK- well , I don’t think there is much we can add then—did you get all of these readings out of—

Conrad

8O- 81- 82- 58- 59- 69- Yeah, that stuff works just like the simulator.

Cooper

We got the readings .

OK - On to 8 .3 - RCS .

8 .3 RCS FCSD rep

Let’s go into the RCS - yeah , I don ’ t think there is anything more—

Cooper

This is all—

Conrad

Yeah, this is all we can do on the REP .

Cooper

OK- RCS Operational Checks - We did just like we had planned in our little book.

a ctivated the RCS and Check Ring A and ACME and direct—al l three axis- Ring B - Check Ring Bin ACME and direct—all three axis and they worked beautifully. FCSD rep

How about the pad checks—were they-

Cooper

Negative

FCSD rep

No pad checks?

Conrad

Not with the sealed system—

Cooper

A sealed system - I’m glad it was-

Cooper

Control Modes - We used pulse and we used horizon scan—

tQEt◄Ttl<L

Conrad

We didn ’ t even check reentry rate command-

Cooper

We used direct, UBed pulse . rate command .

Conrad

We uned the

We used hori zon scan .

I know what it was—why don ’ t you tell them about this—and I ’ m going to see if I can get the fuel f i gures—

Cooper

OK.

And they all worked very ade quately.

I thought the rate command system, I mean the RCS system was an excellent system. It was really crisp and just really, I thought, it was a real good solid system. Rate command was much more-FCSD rep

What about the retrof ire - how did i t hold retrofire?

Cooper

Beautifully , it was just no effort at all- hold—

FCSD rep

1 degree or less?

Cooper

Oh, yeah , easily.

We had a litt le offset

in number 3 and number 4.

I could feel

them offsetting us .

I just cranked in a

little bit of RCS :

Boy, it just glued it

right in there, it just wasn ’ t about -I felt like we could have had four or five times the offset we had—and never have

GQt”EIDE~~TIAt budged it off there .

49 RCS , I mean the rate

command—One thing on rate command before retrofire and just after retrofire, waiting for retrojet , and then starting the pitch up to go up and roll over inverted and go to zero lift , the dual ring rate command is just mor e than you can handle.

It ’ s

just a lot more than control authority than you want—you tend to over- shoot on things because there is just so much control tor que in there .

As I had stated, after

I f ired retro and jettisoned the retropack and pitched up to roll over then from ther eon I went to s i ngle ring pulse, and used that . use .

Reentry rate command—we didn ’ t

Direct - used direct t o do the reentry

on single ring direct and used the pulse mode from r etrojet to 400K. FCSD rep

On the single ring direct reentry did you have—did you feel like you had all the authority you wanted?

Cooper

Yeah—until very late—as I stated some time down , oh, half way thru the reentry

,_C~ Ji Hl:EttT

where you really begin to get the high g , after your high g , in fact, along about coincidental with a real high g, when you begin to get some fairly good oe1cillations , very r apid rate, I had no problE’ms damping them at all but I didn’ t have tt.e time to keep switching back and forth f rom rate to attitude and go back to rate anc. damp them real quick and then go back to &.ttitude and decide where I was on the guide and then go back to rate and damp them and go back to guidance , so I finally—they got to getting fairly good where I had to devote a l i ttle bit of time to damping them , and I f i nally just went to guidance and stayed on guidance andJust flicked over tc single r i ng rate command to damp the oscillati ons and then used the attitude control i n the rate command to steer the computer steers .

Which

worked out versJ well and there was—there never was really any oscillating-you never really—I could go to rate on there and you could hardly ever see the rate needles

Retrofire attitude

Rate Command, reentry attitude

control— I had already mentioned how we shot the reentry.

No primary heater lights .

Heater lights on the RCS - they were on practically—we had the heater on 99 percent of the whole flight.

We turned it off, got

heater lights on Ring A first, brought the RCS heaters on then rechecked-heater light went off and turned the heater off and about five or ten minutes later-fifteen minutes later, the heater light came on and then it was on Ring Band we turned the heater back on and this went on five or six times and finally we just turned the heater on and left it on the whole flight.

I monitored

the temper~~tures f~~equently throughout the whole flight in the RCS Ring A - temperature ran about 70 degrees or about 65 degrees and the RCS Ring B temperature ran about 70 to 72 degrees the entire flight .

<::.:.€0►~FIDE~~T I A L

one time I noted the RCS Ring B was up to 80 degrees.

I watched i t quite closely for

a while and then it never went beyond that and came on back down to about 70. And they stayed there essentia.lly the whole flight .

I think you need thoee heaters

on obviously the whole—all tt.e time—I’d never have any of them off at all now. Thruster firing colIDllents .

When the RCS

thrusters fire at night they clank out what ever you are l ooking at in the night side. The only way you are going to use any night attitude reference i s to watct. what you are doing, get l~ned up in a reference and then f i re a thruster and pl an on ws.iting a few seconds before you can tel l wt.ere you are at again .

They really light t ~ the place .

When you are firing them at night . FCSD rep

How far does the flame stick cut?

Cooper

The plume goes out about— appear s to go out about 4 feet and the plume is j ust the width of the outside diameter of tha.t thruster as i t comes out —it has a little bit of expansion ratio as it comes out and it goes

-’>►4 FlDEfi~Tfii: l’ .;

b4~1DEt◄ TIAw

r ight up just about that size—it grows very slightly but not a heck of a lot and s o it’s just about something i n the order of 4 inches diameter.

Something like that—it

has little expansion ratio—i t expands as it comes out the nozzle slightly, and the~ it just goes sort of like a column and it fans out very s lightly but it goes up something in the order of 4 to 5 feet distance from the thruster. FCSD rep

Did you ever get any pictures of that?

Cooper

No, we didn’t .

We had all our cameras

stowed at the time we got that cranked up . We intended to.

Systems Shutdown - It

worked just like advertised and we turned the prop valves off , very shortly then it rtms out of f uel and stops firing and you notice that there is a little burning around all the nozzles.

There we got a little

residual fuel—not much—just a little bit-it dribbles and fumes after i mpact- -probably very neglible.

I don;t really think we got

them after impact , I think we got them while still airborne .

But they were almost

There was

just a very s light musty odor in there- - fume. Not sure— I’m not sure that p~rt of this odor isn ‘t part of t he ablati:1g going on because fiberglass ablates with pretty high fume rates.

The mobility of the suit is nJ better or no worse than any other suit .

I had to sort of

That suit circuit ran

We had to really shut it

completely down to get above 55 degrees t emperature on the suit heat exchanger outlet and generally it ran around 50 degrees which just froze my rear off and I had my suit flow . . the general configuration we had was both of us

I had mine clear

back to almost a minimum position and we had the suit coolant loop shut down to where it was just about a half to one notch open from the fully OFF position.

Did you cover the . .. the exact detail s on this DCS? How we didn ’ t get the light.

The only time

we didn’t get the light. Cooper

No, I didn’t cover the details on that Eixcept just that we had gotten DCS unforecast over Carnarvon after when we already had our load in from Houston, and then it came on unexpectedly, not ev-en checking to see what mode we were in here,

We we•r e in re

entry mode and sent us this DCS updatin€’ our TR and updating our load, DCS load there, and just as he said he was sending, why rapidly then we switched out of reentry to prelaunch but never got any DCS l i ght on either the TR or the load. Conrad

Yes , he s ent two s eparate commands, and theoretical ly the light should come on each time but I never got the lights, so I’m highly suspicious of what hap pened and I’ve got to have an explana tion why this load…

Cooper

Which he verified to the cores and they checked out

ak0tr4f.lDEt-4TIAL

all right. Conrad

Yes, it was address 03 and address 10 and they ver ified okay and that seemed to convince everybody except me that the load was correct and my mistake, in retrospect, I should have made them ,transmit the load and either satisfied myself that the DCS light had burned out, or that the operation did take place truly in the ma.mter in which it was supposed to and it did light the DCS light .

He knew the TR

was right because he had his TR clock synched in with the spacecraft TR. Cooper

And he assumed the load was right because he got maps back on it, but … .

I’m not too sure I …

Conrad

Yes , that’s pretty dangerous. Pretty dangerous .

Cooper

I think this is it as I jus t pointed out to J . B. and we were discussing in the corridor here, my feelings on it are right now are real strongly, that my recommendation would be to piloia during really critical time periods, “I’d just turn the DCS circuit breaker off.”

I wouldn’t even fiddle with

it because that one violation that of everything we had agreed on has just completely destroyed my confidence in the whole set up .

thing it did though, there was one ancmaly that I saw on there and I almost had a heart attack at the beginning of the flight.

Now, there was one thing there, I don’t know if it was the radar or the computer.

But , the first

time we flew over the Cape and locked up on the back up REP on the ground, it read out the digital millage to a gnat’s eyebrow.

It locked

up at 248,66 miles and I don ‘t believe it will read any higher than that supposed to be 250 , but I had the same number at the other end so I suspect that that is as high as it will read out.

And it

tracked t hat thing right over the Cape where we got down to, I think we got down to … our slant range at the closest approach was 161 miles or something like that, and everyti.me I punched it up to the range went do’Wl’l. and - Cooper

Man that was really beautiful, just beautiful, The radar itself stayed locked on for … I felt like you could a lmost point out the tower it was right on the mila.ge mcxl e.

Conrad

But in the catch up mode it read out to 248 . 66 miles both at the start of lock up and the end of lock up , and I was really impressed with that. after that we always locked the Cape .

Yes, but wait a minute, your analog readouts only go to 300,000 feet and that’s 50 miles El.l’l.d we were never within 50 miles of it, so …

Cooper

Yes, but they rea d correctly and I got Hteering, radar steering.

Conrad

Yes, but the analog couldn’t have read correctly. If it read anything on your scale it wa.E1 wrong because it should have read only digital … .

Cooper

What I saw it was showing that it was getting a r eading.

Conrad

Oh, yes, well , there was no doubt that ue were locked up.

Cooper

The R dot was going right on out past there , you know, and then it came on past .

Conrad

But I don’t know whether if the problem in the

digital read- out was a computer problem in the catch- up and rendezvous mode of accepting radar data or whether it was radar problem, but I ’ ll mention under the computer becaus e I sort of suspect it was a computer problem. Cooper

Okay, control s and displays, sequence telelights . The only comment I have on sequence t el elights is that the comp light on the comput~r is too bright.

That ‘s right.

We are going to have to have some way of iimming that or put some tape over it or something, because

Conrad

That ‘s a comment for GT-6 especially.

Because when you are running it at night with the computer on for rendezvous, that comp light darn near blinds you.

Conrad

Yeah, it I s really bright .

Cooper

Well , that ’ s something somebody ought to check out . This is just a comment.

Conrad

But we never did have any reason to dim it in the simulator.

You never tried to look out the window.

Cooper

You don’t have anything to look out the window at.

Conrad

Yeah.

Cooper

We never powered it up in

It was very jerky on the wa:y up .

It was erratic going up .

And I don ’ t guess you ca.n expect a pressm·e alti meter like that to follow as fast as that booster is moving.

Cooper

Conrad

Coming back on reentry, why, we were apparently a lot slower on the other aide of it, because it unwound in a.n extremely steady manner and it seemed to be right with the barostat .

Cooper

It was right on the barostat , actually.

Conrad

And this is really the important thing.

Conrad

Yeah, we didn ’ t have a:ny reason to look at it.

Cooper

I forgot about t hat .

Conrad

No, we got busy doing a check there, too.

Cooper

Well, we were also having a couple of radio calls in there and it was int errupting —

That’s the only time I used it.

I used it once for

Before we go a:ny further, while I’m thinking about it, on the pad out here, you said you could see that umbilical tower when they started to raise it.

Conrad

No, the erector.

FCSD REP

The erector.

Conrad

You could take t he mirror out of the holder and hold

it at the bottom of the window, and you could measure the distance .

Now I don’t know exactly how high we

are above the road, but where the road winds up to the pad and makes a left turn in and drive straight into the pad, you could see the intersection of that road.

So, I S83 that you can see the ground some

I could see

I knew we were fairly low .

a matter of fact, that altimeter was just about on the money, wasn 1 t it? Conrad

We were at just about zero feet when we hit the water .

We had a good altimeter setting.

Cooper

Almost exactly zero feet.

Conrad

Th.is is what McDivitt said.

Don’t go on that 29 . 92 .

They gave us a 30 . 10 altimeter setting, and when it read zero we were on the water. Cooper

Yes, that was a real good one.

Conrad

So , I recommend they stick with this — giving the altimeter setting in the recovery area be,~~ause it can make the difference of a co~~ le of hundred f eet .

No.

That was straightforward.

It acquired in excess of 250 miles and read at 250 miles.

Cooper

That’s that.

We never had any false lock problems

We didn I t really give these a fair shake,

however. Conrad

Yes.

But, from the testing that we did, we encountered no false locks.

Lighting, indicators, and instruments.

Conrad

Okay, there’s a def iciency here.

No doubt in your mind.

You need to see

that center instrument panel, and Cooper

You need some kind of glow.

You need some kind of

a little glow down t hat center instrument panel to be able to see that t hing. black . Conrad

That thing is really

Without bringing that big darn

I really don’t underst and why those guys took that r ed center light out.

Cooper

Whil e we are talking about lights, let’s see if we cover that.

No, we don’t.

But there is a real

safety- of-flight item in t hat cockpit

lighting.

That is, if you leave a:ny one of these lig·hts on, and, in particular, the big bright center light which is the landing light — I think it is on ther e

in the light solenoid area , the reostat,

you build up a heat thing that is actuall;y- to the point of being explosive.

I t actually gets to

•eet*t8 i ~q;rw.L

where it will burn -Conrad

Yes , you could smell paint.

Cooper

It burns the paint in the spacecraft .

Conrad

You can smell paint cooking.

That’s the first

thing that we noticed, the first day.

I ‘ll tell

you what heats up.

Well, the

It ‘s the reostat .

thunderstorm light th.at Gordo 1 s referring to doesn’t have a reostat. Cooper

That just flat puts out heat.

It just flat puts out heat.

You can burn your

Your under-window right and left lights — if we ran those at great periods of time with the light dimmed down , th.at reostat gets so bloody hot th.at you can smell the paint cooking again.

I felt that

that was a real bad sit uation and we have comments on th.at -Cooper

So we kept rotating these lights on and off.

Conrad

We never did burn our lights too steadily unless we absolutely had to .

The other problem there was that

anything that generates th.at much heat is going to have a tendency to burn out, and I ‘ll tell you, you lose one of those cockpit lights, buddy, and you are screwed. Cooper

You really are.

Conrad

I had already busted my au.xiliary light a.nd if I would have burned out the light on the right i :‘.lstrument panel, we would have had to rtm that center light a lot, and I don ’ t think that center light would have lasted either.

Cooper

No . I think that whole center console area is a very weakly lit area.

It could certainly stand a very, very

faint soft light.

When you are rtmning 1mder night

light conditions you’d be able to see thn radio swit ches and this type of thing.

Let ’ s see, indicators and

instruments—well t of course t a pet peeVE! of mine is that we couldn’ t get EL in the 8- balls .

I still think

the 8- balls could certainly be lit a lot better, al though they are satisfactory for what we ’ ve got.

think the-Conrad

We really didn’t use that except during lift- off and reentry, but it does shine.

Mine shines in your eyes,

doesn ’ t it? Cooper

Yes , there is a real bad f eature in the cockpit in that a:ny lighting at all, either one of the right or the left lights- say Pete turns his right light on, particularly—if I’m trying to look through the reti cle,

it just zaps.

It ‘s gone.

Can’t see a thing in

101

there with a.ny light on in the cockpit.

In order to

use the reticl e , you have almost got to dim out all the lights in the cockpit, and this is pretty ha.rd to do because you need to use some around. Conrad

And , you know, they bad a light down on the center pedestal shining aft that was supposed to light up the water management panel, and everybody took it out. You have to do most of your work on that water manage ment panel blind.

I mean, you sort of put your hand

in there backwards and everything, and , as long as everything runs all right , you only need that one switch to go from off to overboard.

The other two

switches stay in the normal position unless you have some sort of problem.

But it would be nice to light

up that whole area down there.

There is no way,

without a flashlight or pulling that auxiliary light way over there , to tell how much water you have in the water tank. Cooper

I don’t think you can tell with it.

I took that

auxiliary light and got back in there and practically crawled down in there.

With that darn M- 1 experiment

thing installed on t0p of the tank there , you can’t see the water level bubble anymore.

They i nstalled

102

Pete’s M- 1 experiment right on top of the water tank where the water level bubble and the mea3uring gauge is . Conrad

It ’ s built right on over it, so you can ’ t see it .

We used every combination of l ights in t :1ere that you could think of, depending

on what we we:re doing.

Sometimes we ran with Gordo—if one guy was sleeping, the other guy would run with his red lights on dim. And many nights, we ran with no lights at all .

had that much confidence in things like 1!abin pres surization and so forth , that we just powered down the lights and we would go through whole night sides without ever turning the lights on and never even looking at the instrument panel when we were in dri::ting f light. We would both nod or look out the window., Cooper

Or sleep.

Conrad

Yes, and one of the reasons we did this Has because of this heating problem.

I had a decided fear that we

would be in real trouble if we burned ou·; any light . We had no way of replacing them.

So , an;:r time I

could conserve elec t rical lighting, by saving the bulb , I would turn the thing off.

I didn ’ t want to

build up big hea t loads in them.

We ran red lights ,

we ran white lights, we ran the center lights only,

-e@N Pl8ENTI

103

we ran the left side only, we ran the right side only; we ran them in a:ny combination you could think of, just dependent on what you wanted to do with them. Sometimes you needed lights in the daytime , sometimes you didn’t need lights in the daytime .

It depend s on

what your orientation ~a9

and what you were doing.

That was very interesting.

It’s an entirely lighting

situation than in an -ai-rplane . Cooper

Let ’ s see. We checked out the one light that we hadn’t mentioned here.

I think we mentioned all of them ex

cept the doggone docking light.

We did check it out,

and it really throws out a nice light out there . didn ’ t have anything

to try it out on out beyond the

nose, but it sure lights up the nose.

As a matter of

f act, on that onenlght side we kept wondering where in the heck that light was com.;_ng from. Conrad

I kept saying, “Hey, the sun is really shining on the nose for a long time . ”

It was the night I blew up the-

Cooper

We were pointing straight up.

Conrad

Yeah, I ‘d blown up the shrimp and gotten it all over the right console, and when I was cleaning it off, I had inadvertently turned on the docking light switch. It took me about 10 minutes looking out there trying

-€0i’IFID Ef~TIAt

104

to figure out what the heck it was shinj ng out there on the nos e .

It finally came to me in a. flash that

the docking light was on.

Now that is another thing-

I don ’ t know how they covered that REP with the re flective t ape , but, man, that thing wa s bright! Cooper

All you could see was the light.

Conrad

No , I mean in the daytime.

Cooper

Oh yes .

Conrad

In the daytime with the sun shining on that thing, it almost burned a hole in your head.

Boy it was bright!

Cooper

“{es, actually—

Conrad

It looked like a little sun out there.

Cooper

Pete went into it deciding that he was n~ver going to see it in the daytime , and I think he ha1i a big sur pri se.

Conrad

I was determined that we were go:Lng to see it .

.And we did see it in the daytime, several times after i t had gotten a fair distance away from us, I ’ d say 2 or 3 miles away.

Cooper

It was bright.

It was almost brighter on the day

In fact, it was so bright

I recomment that

you use the same procedure of keeping a log book and a flight plan, because two guys are working all the time.

You put it down in the log book and then you

write it down in the flight plan, and this helps you organize it .

Okay, start charts—by gol 1 y , I thought they were

112

r eally good, and I think anybody that wants to get lined up for a night retro, if they do :_t once and aren’t convinced that star charts were pretty use ful they’re -Conrad

Well, it gave us a great deal of confidence to go into the star chart the last day and pic:k out the right yaw stars, and then, as we were aJ.ining the platform, to see those yaw stars go right through the middle like they were supposed to.

Cooper

I think the star chart was very usable snd very neat, much smaller and neater in this fashion than it is in this great big mechanism thing we hav-e .

I think

they’re very usable in that fashion. Cooper

Stowage.

Hah!

What are we supposed to say about

stowage? Boy, it’s probably the most critical thing in a long flight . basis .

It has to be kept up on an hourly

Belts and harness— I thought they were

perfectly satisfactory, except for one set of bel ts I wanted to get out before the flight and if I were doing it again, I’d take my own scissors down there and cut them out.

That is the knee belt which was

put in there for pressurized ejection .

I t is still

in there, and it is in the way, and I hated the darn thing.

Mine flopped and f l apped around in there .

113

I final ly took them and gouged them down in al ong side the s eat.

I took my scissors and cr ammed them

down in there , and that is where they stayed the whol e fl ight . Conrad

Yes , I ’ m not convinced they are necess ary.

Cooper

That knee restraint belt was put in there so that if you were ejecting at high al titude and you came out in a pressuri zed condition - -

Conrad

I think the arm restraints ought to be l ooked at the same way.

Cooper

My arm restraints stayed in the down position , I l aunched with them down , I r eentered with them down, and they never came out of the down position.

They

could have s aved a good 2 or 3 pounds of weight on my sea t by taking my arm restraints out .

I t old

t hem that before and they said , “Well, they woul dn’t ever be abl e to get them of f . ” You know the seat was out s itting over there and I coul d have removed them my~el f in 5 minutes when we were in Weight and Bal ance .

They said the paperwork involved in re

moving them would probab l y take a year.

So,’ those

two items I f l ew with I thought were compl etel y worthl es s .

And the lifevest- - I don ’ t know what

you are going to do better .

honestly !mow what you are goi ng to do better because of the ejection situation, but they are in the way. They are in the way of everything you do, and they are real little bearcats to get on and off---these little lifevests. Conrad

We didn’t have a place to stow them.

Cooper

Yes, we left them on the whole darn time just because we didn I t have anywhere to stow them. really in the way.

llut they are

They are a real pail’.. in the rear.

Conrad

Yes , it ’ s all part of the suit combina tjon.

Cooper

Well, that’s right.

Conrad

If you didn ’ t have the suit, they wouldn.1 t be so bad.

Cooper

Waste disposal- pack harder.

Conrad

Yes .

Cooper

Pack tighter.

That’s a very grave problem, in the

f act that as you start getting defecaticn wastes of this type you want an area where you are not going to mix ing that with other items too much, and you want an area that you start packing right the first time so you don ’ t have to keep dragging it all out and repacking. I don’t !mow how you are going to do it any differently than we did~in keeping one area completely open for it, and just working and using that for your disposal

FCSD REP

How about urine?

Cooper

The urine system worked just great .

Conrad

Except for one problem.

It leaked on occasion, and

I really attr ibute that to the fact that this rubber device gets covered with tars .

I cover ed t his pretty

thoroughly with the doctors .

I recommend that you take

new urine rubber receivers along, one per each day of the flight .

We had four along and we changed t hem

every two days .

They get gummy and tarry and they

Yes , I ’ m not sure they don ’ t even wash then out occasionally.

Cooper

Two other things we have is that you leave preheat on for 4 minutes prior to flushing.

We got one

t remendous big glob of urine ice that broke off sometime about the fifth day. Conrad

Oh, yes .

Cooper

And, man, that indicated that it really bui l t up . It must have been as big as that box there .

Conrad

It looked like one of those sand castles you build . It was a conica l buildup of ice . had flowed out . up .

The liquid

It kept building up and building

But it was still flowing out through the center

The darn thing broke off one day

It just went floating right by the spacecraft

and it was pure yellow. Ha , ha!

It was about 3 by

It was triangular , dribbled

up, rough shaped, but you could see where it was smooth on the back side where it had actually s tarted to freeze.

Boy , that scared us .

We didn ’ t want the urine

system to freeze up so we went to 4 minutes .

We used

the recommended McDonnell procedures and we revised those slightly when we found out the tar was beginning

We ’ d built up a pressure in there when you would start to UJ1inate in that thing .

We would open it

up and dump for 30 seconds after we went through regular dump cycle and evacuated the bag.

woul d open it up to the cockpit and let it dump 30 seconds which is what MAC recommended .

Then we

woul d sit there and cycle it on and off a 1d have that vacuum suck around down on that valv,~. Cooper

Open and close that valve dry .

Conrad

We cycled it three or four times rapidly with the vacuum opening and closing it and then we shut the system down . not.

Cooper

I don ’ t know whether that helped or

We had the impression that it did .

It made us feel better about the whole si·;uation. At least the thing worked the whole time .

Why don ’ t we finish this sleep period?

Cooper

Okay , sleep period .

Okay .

I think the schedule needs to

be set somewhere around the normal s l eep cycle that a person has a l ready, in other words , I don ’ t think that the s l eep ought to be set for mid- morning or mid- afternoon .

And I personally think that the

cockpit is small enough that you ’ re al mos t going to have to s l eep both guys at the same time . Conrad

I concur .

I don ’ t think you can be doing the ex

And have the other one as leep .

Conrad

Yeah.

Cooper

Pete and I both found that the times when we really slept the bes t and most comfortable and real ly got some good sound s leep was when we powered that thing completely down and turned all the l ights out and were down around the backs ide area of South America and there wasn ’ t anybody to cut in and be flashing in to tell us all kind of things and they woul d leave us a l one and we just both power down and go to sleep and get a good s l eep .

And that is the only

way you are going to do it , becaus e if one guy is

126

doing experiments or working, or if one in the spacecraft, or doing all this other stuff, the other one is just not going to sleep.

This i~: pure and

simple as that. FCSD Rep

How about mentioning about how quiet it is .

Cooper

The inside of the spacecraft is just as quiet as the inside of a very quiet office room .

Conrad

Yeah.

Well now , the big thing here is ihat we had

taken our helmets off and put these neck dams on so we had no, none of this suit air flow over the mikes.

And when you get in that configuration so

you are not picking up any noises, as a matter of fact , we had our intercom volumes turned down .

Most

of our talking we were doing was to one another. Cooper

We were just talking in our normal tone of voice.

Conrad

And our radio volume levels were extremely low . were carrying about 4 on our radio volumes . that was more than adequate volume.

And

I mean that

guy came in loud and clear in the headset.

You

could hear a pin drop in that spacecraft .

The only

sound that you were aware of was a very gentle swishing sound of air which was flow due to the recirc being open . Cooper

Right .

127

Cooper

And it was so quiet that you could hear a guy when he picked the book up and started turning the page .

Yeah , I could hear in back in the adapter section after real ly getting adapted to this thing , we could hear the hydrogen vent , we could hear the fuel cell hydrogen purge . purge .

many other noises working back in the—There was a pump package or something squeaking back there that squeaked for all through the test period and I was curious to see if I was going to hear it in flight and sure enough , it was loud and clear .

back there behind my head in the adapter section. And you could hear jus t anything that was out of the ordinary noise .

And that was what the pr oblem

was , it was so blas ted quiet in there that when something did click or snap or that was not cyclic in nature that you got used to it woke you up just like that .

And as Gordo says , turning the pages

i n a book , or he ’ d reach over and pull something off the Velcro , jus t a little food package and just that little zip of the Velcro sounded like it was magnified in ther e cause it was so blasted quiet in the spacecraft .

He couldn ’ t talk in the micro

phone without me hearing it . Cooper

I tri ed actually cupping my hands and talking into my mike here so I could make as little n)ise as poss ible .

Conrad

And I tried it too .

We would wake each )ther up .

So our recommendation - I ’ m sure the spa~ecraft is safe.

You may want to look at something - I really

don ’ t think you need this, but I think it should be looked at f r om an engineering point of view - what would - what are the catastrophic things that could bother you i f you were both asleep that ·,,rould need somewhat of a warning to wake you up and I real l y don ’ t think you need any myself . Cooper

I don ’ t either .

Conrad

But I think that the spacecr aft - and we felt that

way in flight , and we did ; we both went to s leep at the same time .

And I ’ m sure if we would start

losing pressurization our ears would have told us that we were as sensitive to that as we were to noise . Cooper

Thi s schedule we have covered that , I think it should be in .

Because invariably, we could get busy

doing other things and have many interfer ences and it would wind up that we would both wind up sleeping during the normal Eas t Coast nighttime cycle .

variably, we just weren ’ t sleepy at other times . Conrad

Yeah , I think the other thing is that now in the schedule my naptime al ways took place when we were cleaning the spacecraft . the stateside passes .

This was too short after

rest of the sleeping cycle . stick to it .

Although we tried to

Gordo woul d go to s leep for his long

We always ate our

meals together and we were scheduled not to . always took the vision test together . this way we compr essed things down .

We weren ’ t , And uh , then

I usually wound up having about 5 hours off , but I never s lept the full 5 hours .

There was just one

night that I did .

There was one night that Gor do

slept maybe 6 or 7 hours and I let him Eleep that whole time because we were just exhausted.

And

that was the same reciprocal thing — he let me sleep for 6 or 7 hours .

That was the on ly time in

the f l ight that we both real ly s l ept any long period of time .

The rest of the time I don’t t hink we ever

slept longer than 2 hour s at the most — And most of the time it was 50 minutes between s t ations. Cooper

Well, that ’ s the whole thing , that the — on this schedule thing there are many , many, many inter fer ences to sleeping and these stations just calling in letting you know that they have TM sclid and are standing by, interfere with you— they wake you up.

Conrad

They shouldn ’ t even do that—on backside passes un less they got something to give you , they shouldn ’ t even call you .

Cooper

And then too , when they start handing ycu a bunch of flight plan updates and they want yoi:.. to do this and that and one man is trying to be— ttey ar e try ing to keep one man real busy whil e the other sleeps , just doesn’t work out. close your eyes .

I will say one

thing right now that we haven ’ t mentioned befor e , I believe the Polaroid window f i l t ers we took were the greatest things we had along. Conrad

Es pecially when we got on that drift in fl i ght .

Cooper

I ’ d real l y r ecommend thos e very strongly,

We put

was Lake DePoopo in South America and here again the l ake was fairl y distinctive although this was a shallow water lake - the other lake was i n the mountains in a fairl y deep water - crater-type lake, whereas this Lake DePoopo was a flat land lake fai r ly shallow , the lake was not the same shape as on the map that we had of it .

It is the onl y i slanc it can be,

i t is not exactly, quite different in reality than it is here on the thing .

The island is changed in

shape, but being a shallow water l ake you can see that the lake could very r eadily change with the water level - - change shape with the water level ; and these islands could very readily be modified fairly readily just by dredging or hacking away at them .

It was obviously the only lake in tha t im

135 conditions were again fairly late-in- the-afternoon type light conditions, but they were good enough . I don’t think this lake was nearly as distinctive however, as the Lago de Winemarga .

I don’t think

you can trust these shallow water lakes as being that definitive in that they may change a little on you and won ’ t show up as good , particularly f r om higher altitudes I don’t believe, as the deeper water lake perhaps .

And the next one , let ’ s see,

as to time—days and times— first of all , I was skipping that, day 2, 21 hours 45 minutes 39 sec onds was Sequence 212 which I covered, Sequence 213 which we just covered was day 3 , 21 hours 38 minutes and 2 seconds; these were all made at — 212 was made at 1/250 at f/8 because of the quite low light value, and Sequence 213 was made at 1/250 at 9.5 and then one at f /8 , because here again, it was a fairly low l ight level.

on the La Palma Island , and very distinctive ; how ever, one can get confused if there LS any l ittle bit of cloud cover at the isl ands yo·1 1 r e l ooking at .

There are approximately five or six islands

out in this group and with some of t :1e scattered cloud conditions, vou can get on the wrong island there fairly readi l y, particularly i .: part of one island , where partial l y covered by cl ouds , maybe just a point—you can very readily g1~t the wrong po.int .

However, I think we got the :~ight point

all right without any problem .

And :: think the

lighting condi tions were very excel l nnt , really , except for the scattered c louds on the water down there; the lighting conditions themsdves were good for these pictures .

And on day 5 , 10 hours 25 min

•

< Qt; f IDflsl1\AJ; other .

137

In fact, the one that is the most distinctive

from quite a distance out is Cape Sim near Osaweira. It is a lot brighter, lighter colored sand and is more distinctive than Cape Rhir .

However, once you

learn the place , Cape Rhir becomes a little more distinctive when you learn what to look for , because Cape Rhir is at the edge of the mountains and just to the southeast of Cape Rhir , there is a river and a valley—a big, wide, green valley which travels up to the east along the edge of the mountains . When you once learn to look for it , this river and valley are quite a give- away , because look just to the left of it and that’s Cape Rhir .

I think , prob

ably it is the most distinctive of these three.

The

three points that show up immediately from perhaps 800- -1000 miles out are Cape Hodad and Cape Sim and. Cape Rhir .

You can see all three little points

sticking out there .

Neither one of which are

particularly more distinct except this Cape Sim has

brighter colored sand and begins to show up a little more distinctive, but once you learn where the land marks are , these mountains and valleys near Agadir give away Cape Rhir .

I believe it is the best

landmark— in that immediate area.

I ’ m not sure that

138 I agree , incidentally on all the Apollo landmarks landmarks we ’ ve got here .

I ’ m not sure I agree , in

general, with any of the Apollo landmarks that they havp .

I think there are lots more distinctive l and

mark features around the country.

I think that

their idea of selecting a point of land down in the water is good, but I think that there are numerous places around the world where , say a large river comes out and intersects with the ocean naybe at a point , at a point in a river and things ,f this type , would be even more distinctive or an inter s ection of a river and the ocean , or an intersection of something in the type of causeways i n Miami or the causeways here at the Cape where the;r cross the water with a very prominent water landma:~k .

They ’ ll

give you a very accurate telescopic poin-; to sight. on , whereas the particular points of lancl that they have selected are not really accurate type sighting points for real accuracy , I don ’ t feel .

They’re

r easonably distinctive, but I don ’ t thin}: any—nearl y a s distinctive as a lot of other areas around the country that could be selected. FCSD Rep

Okay, why don ’ t you look through these things her e and see if there is anything there that you haven ’ t covered.

139 Cooper

Okay, let ‘s see, going down on the 9 , 0 Operational Checks - Acquisition . .

FCSD Rep

That’s Apollo Landmarks.

Cooper

All right, the—I think to find these landmarks, things of this type , one thing that I feel pretty strongly that you really need is a platform. need a platform to operate from.

You

You need pointing,

something to give you pointing information .

Now,

you can find it approximat ely with the plat form off, and by knowing about what BEF or SEF are , and by yawing approximately so many degrees , knowing what time to look for it, approximately what degrees to pitch down .

Chances are, if it is fairly dis

tinctive you are going to find it.

But for certainly

very accurate acquisition , you certainly need a platform up and some accurate pointing information, then you real ly got it pinned. Cooper

We tried it both ways and there is no comparison. If you really want to make sure you get on a target,

”

if you ’ ve got a time and a t the time you are at this time, then the pitch angle and the yaw angle to be at, boy, you just can ’ t miss it .

If you go

to those angles just a few seconds ahead of time and set right there and as you come up on the time ,

You just don’t

Updating, of course , you ‘ve got to keep

these times updated as you—depending on your ephemeris, and how you are sliding around on your original time.

Ours, fortunately , was just right

on the money practically the whol e mission , fairly late in the program we began to decay enough that we were changing times fairly significantly, but the weather is the biggest factor of all .

Of course,

if t he weather is bad in the area, you do:1 1 t get it . You just don ’ t get the t arget .

I f it exists , humidity

l ike you find along the West Coast of t he United States

then you aren ’ t going to get it

although

some places out there like the point by Santa Barbara and Point Arguella and some of those poin·~s, even in spite of fog and haze , almost i nvariably Bhow up . These are the kind of things that should be taken into consideration .

The weather is pr obably t he

biggest factor on whether you are going to get a point or not .

Sun angle is not so importcnt as

weather, although it definitely is a factc,r in that very early or very late the sun angles ree.lly tend to cut down the visibility, particularly if you have the addition of humidity in the air .

“COMFf D ~

If you have

• the addition of humidity in the air.

141 If you have

high humidity and then low sun angles, you are out of luck .

If it is a very dry humidity, the low sun

angles don ’ t hurt you nearly so much .

The sightings

—there again the ease of which you are going to get your sightings done, get on to them and get them spotted and so on , i s going to be dependent on the landmark itself .

Those of them that we got, I think,

are certainly reasonably landmarks , although some of the confusion things can be- Conrad

I just found out why the whip antenna didn’t go up . It was my fault .

Cooper

Why is that?

Conrad

Because I powered down the common control bus. Remember, I turned off all squib batteries to save batteries later.

Cooper

You didn ’ t turn those off till later.

Conrad

Well, I know I didn ’ t, but I pr obably turned them off before we ran the antenna up though , or tried to.

I ’ m not really sure.

Cooper

I don ’ t think so .

Conrad

Well, don’t mind that.

If it comes out , well , that

was the reason. Cooper

I remember when you powered those down. t

We had

142 already gone through all the sequences ~1d everything by then. Cooper

Okay, let’s see.

Designated targets—

FCSD Rep

I think you have covered that pretty much.

Cooper

Yes , a ll the targets .

FCSD Rep

The targets that they have designated versus what ••

Cooper

Yes .

Okay, well the designated targets- — There are

some al ternate targets right in the are1:.s here that I ’ ve already mentioned.

I mentioned a c:ouple of

cases there that could possibly be bettnr targets than the ones that they selected, although there is nothing wrong, particularly, with thr, ones that they selected .

I personally liked a little bit

better than on target 212 , or Sequence 212 , this point of land .

I thought a little more distinctive

was the point of land that came out of a l ittl e town called San Pedro, just north of there on the same lake .

That ‘s spmething to consider .

It ‘s a

point of land that is quite distinct because it is fairly heavy.

A big mountain sort of c:ame right

down into the lake and dropped off into it , and it · was quite a prominent point of land .

::t is very

shear and precise, whereas, it is a l i ·;tle bigger point.

Although, from a great distanc,~ farther out,

••

the point they had might have proved to be better. Maps—Boy, we ran the gamut on them, but in general, the Apollo maps we got were just stinking.

They

were lousy and they didn ’ t give you any lead-ins to where you were trying to find these things, and if it hadn ’ t been for Harry KazU1DA. ’ s map over there and our regular orbital map , we never would have be gun to have found these places .

We couldn’t have

possibly told where they were .

And the Apollo maps

that they have on here, these colored lithograph types gizmoes things, are just worthless .

They are not

worth the powder to blow them up with .

There are

several real typical examples of why these maps are so bad .

For instance , right here, just on the better

map of the group , they have the Canary Islands, but they don’t even have all of the islands in the group. The island that you pick is sitting way up here at the corner of the map and you don ’ t know what’s leading you into there, or whether there ’ s maybe another island just right by that one . bigger scale map like this one .

You need a

That was a little

too big a scale perhaps , really, but that ’ s the kind of map you need to really point out what you need coming into it, and s omewhat of a more reasonable

I think the prime example we had of any

difficulty in map locat ion was not on the Apo llo maps themselves , but i t is exactl y the srune kind of thing.

What was that one that had the lit tle i s land?

Conrad

Lake Depoopo .

Cooper

No, no .

It had one tiny l i ttle i sland right off

t he coast and it wasn’t on the Apollo mapB .

It was

It was a D- 6 . a ll it was .

That was that thing off BrE,zil.

That’s

It was a chart of water with an i sland

in the middle of it .

It turned out that right at

the edge of the chart was another island .

We took

the wrong island first because , heck, it looked l ike there wasn ’ t another island-Conrad

I’m just making this comment because it will apply to the Apollo map making, as well, and this was an ideal example of how t o really screw somebody up .

Cooper

We a l so got another isl and right up there .

We got

it and we were sail ing along thinking that was a good shot we made of that island, and we fooked down and I said, “Hey, look down there. that.

That ’ s another one.”

I swung over on it ,

and he said , “Let’s get it , too .”

So , we discovered

E~PID[NflAL that it was the one.

145

It was just by accident that

we got the right one. FCSD Rep

Cooper

Okay.

Detail—which of these do you think would be

best?

I think you covered some of this.

Well, I think that coastline is the best, distinctive features on a coastline . mountains .

Next best are rivers and

Probably, if you can have combinations

of the rivers, mountains, and coastlines, these are quite good.

A river running into a coastline and

into the sea, I think, is a real excellent one. Very good.

And roads- -boy, there is just no getting

around it that roads make an excellent landmark area. They really show up.

And a road in the right area

where it is contrasty will really show up for a long, long way away , like a white concrete road and darker background, a dark green background, really shows . . And then, I guess cities show up probably the least of anything.

They tend to have enough vegetation

and foliage and everything and they kind of blend in.

They don’t reall y show.

Okay, I think that ’ s enough on that .

Cabin Lighting Survey Cooper

I ’ ll let Pete comment on that one .

Conrad

Well , it was very straightforward, and we didn’t get very many of them, mainly because WE! wound up in drifting flight .

We took the measurements as

advertised , except there is one little ~:litch in the thing .

They wanted you to take a light measurement

out , the , window, and they wanted you to c.o it in either the heads- up, or heads- down.

In doi ng thi s ,

that said the horizon was in front of ycu.

Now the

light meter reading looking at the black sky just above the horizon in the daytime , which was the total sky, was usually a number around 11 . 5 .

But

looking at the earth, or just below the horizon, the meter reading was about 15 . 6.

So, I al ways recorded

two readings , the reading for the horizon and the black sky, because I didn’t really know which one you wanted . out that way .

With the spot meter the thing just turned Okay, we made one at 01+23+10.

Gordo

-GQMEilQEt{l:1 AI D made one at 05+04+30+00.

147

I made another one at

03+01+45+00 , and we had another one at 04+22+40+00.

Out of those, two of them were in drifting flight, and the other two were heads-up .

And I had this

recording that 11 . 6 was equal to black sky and 16.8 was normally representative of earth background. That was it.

It was straightforward.

9 , 3 SPADATS Tracking Check Conrad

We did it.

We did it by turning our beacon on so

they could just track us, but we , of course, didn’t get into it with the REP thing.

The SPADATS thing,

actually, was supposed to take place during the REP operation, and it didn ’ t.

But we did turn on our

beacon so SPADATS could track us one time over this Willia.mtown site, or wherever it was.

That’s all

there was to it, so there was nothing to— 9 , 4 UHF Antenna Pattern Test

We did a UHF sequence 03 at 01+10+44+25,

and the angles were 0°, 0° , 0° .

Conrad

No , they just sent i t up and said to do it , and these were the angles they wanted .

They set this up for

us to do. 9,5

Thruster Illuminati on Checks Conrad

Never did it .

We were supposed to do it the beginn

ing of the first night or something like that , and it was in a sleep period time and we were tired and we didn ’ t do it .

After that, we got into either a

power down or drifting situation where we were un able to do it, so it was never done during the flight .

That was never done.

That had to do with the REP

They sent DCS commartds

We never got more than a mile from him,

so we got that 3000 foot transient but we never got the 30,000, like?

What was the transient at 3000 feet

Do you remember, Gordo? On radar when the

REP went farther than 3000 feet , I don’t think there was any transient to speak of. Cooper

I didn’t notice any particular transient, or any noticeable one at all.

I was looking for it.

Conrad

Yeah.

We did the—

Cooper

I had it damped pretty well .

Conrad

We never did get the radar to run for 3 hours, so we didn ’ t get test 5, test 4, no correlation between range and range rate display and visual observations at short range, they all worked very well.

we observed the normal transients that you’d expect, just as advertised on here, and I also noticed that· the lock- on light cycled on and off, on and off, when I was in a standby mode after warmup.

The tape hadn’t run out then .

Then we tracked back

out again and it pointed right to t his f-”.ILA area here at the Cape when we had the needles centered . Gordo was tracking on the needles, and it seemed to work real well.

We are really impressed with it.

As you know, we got it to lock on the REP everytime after that over the Cape , but we never g~t the range to read right .

I don’t know whether that was a

radar prob lem or a computer problem . Conrad

At that time , the voice recorder was working on the first test, and I thi nk there is some in::ormation on the tape .

We didn’t see our own booster.

We were too busy.

We started the flight plan right away and we never turned around to look at it. Cooper

We never turned around to look at it.

Conrad

We sure as heck saw the REP.

Cooper

We saw the REP and saw the REP and saw the REP.

Conrad

We saw the REP bl anket too.

Cooper

The REP blanket, I think we mentioned before, but the REP bl anket someway or other got between us and the REP.

This means that the REP either went through

it or tumbled over it, because the blanket was be tween us and the REP.

Man-made objects in orbit.

Let’s see booster, REP—

They gave us

You haven’t any idea of where You have to have the platform.

One thing that we did find, if their platform point ing at satellites was actuall y the pointing informa tion they gave us for the ground objects, why we woul dn ’ t have had any trouble finding them. Cooper

The pointing information that we got from the ground was excellent.

Conrad

We hacked that time on the second and we were really pointed with the platform up and we were looking right down the pipe at whatever it was that they were wanting us to look at .

The only reason

we didn’t see it is we couldn’t make it out.

But

we were l ooking at it. Cooper

Where it wasn’t

it was kind of fuzzy along there and then where t his glow was the airglow kind of jumped up and was sort of chopped off very sharply.

This was very bright .

I don ‘t know what it was .

It was apparently some

kind of a Aurora effect.

We saw a lot of meteorites

Two different

Yes, that was clobbered .

Cooper

Yes, it was clobbered,

We got right up close to

Actually on the D-6 stuff most of the time the experimenters were up on what was clobbered and they didn’t even bother to give it to us , or if they gave it to us it became clobbered before we got there.

They usually were able to tell us that

it was going to be clobbered and then many times they gave us that the weather was pretty good, but there’s three tenths cloud coverage so you may or may not,

It didn’t bother us too much

expanses over the same areas of excel lent weather, clear weather.

We saw a lot of dust storms

in Arabia and Africa. Conrad

Yes .

You could see those desert storms real clear-

ly. Cooper

The wind picking up and moving the sand al ong. Other days we saw the same areas just as clear with no wind .

Conrad

Beaut iful weather.

It was interesting in those deserts to notice that you could really pick up the prevailing wind t rails.

Cooper

Yes.

Conrad

You know from the sand flow.

Cooper

The way the sand dunes were—

Conrad

And which as I sort of remember back e1omewhere there was a lot of explanation about how the whole desert moves , you know, and you could r eally see these great —! mean for a hundred miles- hundreds of miles you could pick out t hese great obvi ous prevailing wind tracks in t he sand that just stretched for hundreds of miles .

Cooper

Yes .

Conrad

And again t his was in Egypt and south of Egypt - down in t hat area .

Cooper

Well, you could actually s ee by the c 1oud format ion—was odd, too .

The t hing I noticed was,

159 C

you really could see the lower altitude prevailing winds in the cirrus clouds or the lower altitude stratus type cloud you all around and you really could see the wind pattern and one thing that r eall y impressed me , was the- - on cloud formations low altitude cloud formations—up in the Himalayan areas ,how t hat stratus- type cloud would hang-would just completely define the land shape .

You ’ d

see it hang in the valleys and swirl right down in the valleys and you’d see where the peaks were , i t would puff and was quite definitive of the land mass.

And then coming in off the—

you could see the prevailing wind direction in the l ower altitude clouds .

You could see the way

the wind would come in and you’d get the wind shear where it would hit the mountain peaks coming in off the desert areas there and it would kick it up over the peak areas . Cooper

Okay.

FCSD Rep

Let me ask one question.

Cooper

Okay.

FCSD Rep

Was ther e—as far as good pictures are concerned- how many pictures did cloud coverage prevent you

co•lE.-laEhtllAL ~

159 D

from getting? Cooper

Oh, well, a great many.

Some areas—well , just in

general let’s just say that some areaB of the country would be completely clobbered in and we’d be traveling over an undercast for great long expanses of hundreds and hundreds of miles , and anything ·, that was in there would be— anything t o do with any areas we desired to photograph in there whether they were specified immediate areas 01· whether they were just general pupose or S-5 , S-6 , were not available for photography, and yet the next day it might be wide open.

The Himals.yas was

an ideal example of that too.

For twc, different

days we traveled over that , you couldr..’ t see any of the craters or any of the ice flows or anything due to the clouds .

You could. see just

occasional areas and some of the lakee would be open, so it was just heavy cloud cover- through there for about a 2 day period and then it just broke up wide open one day.

Eut there were a great

many areas that there were cloud covered to the point that you could not f i nd it.

For instance,

the Carnarvon or I should say the woodly side

®@r ◄ r1Trt

159 E

•

in Australia was a good example.

Two different

days it was completely clobbered in where you couldn’t see anything on the ground in that imme diate area. one day.

This point Rhir was clobbered in

We were going to get an Apollo landmark

on it and it was just back in under the clouds in fact.

And Kano we were going to get a shot of

the Kano air field , wasn’t it? Conrad

Yes , that was clobbered .

Cooper

Yes, it was clobbered.

We got right up close to

it and there were these low cl ouds hanging in there just scattered to broken clouds and we couldn’t see. Conrad

Actually on the D-6 stuff most of the time the experimenters were up on what was clobbered and they didn ’ t even bother to give it to us , or if they gave it t o us it became clobbered before we got there .

They usually were able to tell us that

it was going t o be clobbered and then many times they gave us that the weat her was pretty good , but there ‘s three tenths cloud coverage so you may or may not.

It didn’t bother us too much

around the coastal regions .

160

Cooper

The carrier was the one thing that it really bothered us on .

Two different days on the carrier

shots doggone it you could see one day— for in stance we saw the carrier wake and-Conrad

But the sunlighting was such-

Cooper

The sunlighting and the—

Conrad

You lose the wake and everything—

Cooper

And then the scattered clouds, too were such that you were kind of hunting for him in and around the scattered clouds and sunlight angle was low on it and we lost him.

Conrad

The day we got him there were clouds b~ck there but gee we could see him for 500 miles out and we never lost t hem.

Cooper

Just the lighting conditions were ideal t hat day and he was also out in kind of an open area in t he clouds . Okay , horizons.

The hori zons were of ~curse , a s

usual , I t hink day and night were fairl;r well defined except as you come into the- -as you go in out and out of the terminator .

Just at that p,~riod of time

where you ’ r e going into t he l i ght or out of t he light through the terminator it ’ s a ve:-:y f uzzy

”

161

ill- defined, odd area- Conrad

Yeah, looking down the sun.

Cooper

Where you have no defined horizon at all. very—a real messy situation.

It’s

The only thing I

noted different about the horizons this time was at one morning, at one sunrise, when we saw those tremendous thunder heads out clear on the horizon—you remember that? Conrad

Yes.

Cooper

Where we saw the horizon well-defined and these great big thunder heads with the handles on them sitting up above the horizon. big thunder storms.

They were those

I would guess that those

things must have gone well in excess of 50,000 feet probably to be that well defined—clear out on the horizon some 12 to 15 hundred miles away you could see that profile of them.

Do you have any

thing more on horizons? Conrad

No .

FCSD Rep

One thing we might mention here while we’re talking aoout these thunderstorms, you mentioned before the l ighting in the spacecraft from this lightning.

162

Conrad

Yes, the lightning was bright enough io light the shingles on the spacecraft.

Cooper

You—the whole spacecraft could be li’;.

You would,

even through the polaroid windows- -with the polaroid windows down full dark,some of these cig thunder storms were lighting the whole thing. Conrad

Well , I tell you we saw some lightning· like I just never dreamed existed.

I mean the lightning

bolts must have covered a hundred miles. Cooper

In general in this lightning—

Conrad

Cloud to cloud

Cooper

In the clouds , in this lightning, in general,these clouds light up like they were a big puff of cotton with a light bulb inside, and the whole thing just lights up .

But Pete md I both

saw several cases where we would see a thunderst0rm a l ittle ways out in the distance , and I actually saw air to ground lightning bolts come right out of the clouds and right down just 11 cho,:,m”. Conrad

There was one storm we looked at for t :1em in the daytime where we saw air to ground lig,1tning in the daytime—

Cooper

We saw lightning go all the way from t he edge of

e!Ol’I f 10E~~ITIAL~~

EiOt◄ Ftl?>et◄ TIAt

163

’

this big black cloud right down to the ground. Very clear. Another thing that was different that I noted that was a little different than the usual type of the whole big mass of clouds lighting up-one long series of thunderstorms, I noticed where there was horizontal kind of a chain—horizontal lightning going over and you’d see it sort of travel along horizontally through the clouds like it was moving from cloud to cloud rather than from cloud to ground . Okay, thruster firing.

You could see every thruster

on the spacecraft fire in the middle of t he night- you could see the glow from it . FCSD Rep

These aft firing thrusters too?

Conrad

I don’t know.

I was just trying to think about

the aft firing ones and we were so busy everytime we fired them that I wasn’t aware of them. Cooper

I don’t know .

We had the lights up in the cockpit

when we were firing the aft -firing because we were busy-Conrad

It ’ s unfair to say without pulling the test, you see, because when we were firing the aft firing

164

thrusters, we were also firing attitude thrusters and the attitude thrusters you could see all of them. Cooper

I don’t know whether you s ee the glo..;- off the af t firing thruster or not .

Cooper

You certainly can feel t hem firing.

You can hear

them fire . Conr ad

It’s not annoying or anything.

FCSD Rep

Somewhere we ought to say here—you said you could hear all the thrusters firing.

Cooper

Every one of them.

FCSD Rep

Now, this is with the helmet on or off?

Conrad

Off .

Cooper

Off .

FCSD Rep

How about with it on at separation?

Conrad

I bad the impression tbat at separati)n tbat I could hear them firing .

The aft thrunters with

the helmet on and tbat is- Cooper

Yes , I did , too .

Conrad

Simply because everybody said they couldn ’ t hear them.

Cooper

I thought I could hear the- -

165

”

Conrad

There’s no doubt in your mind that they are firing.

Cooper

Yes . I think it ‘s almost more a matter of—

FCSD Rep

Did you fire t hem before you separated?

Cooper

We fired them just as we separated.

We hit SEP-

the spacecraft just as we-Conrad

Gordo counted them down 1, 2 SEP and I hit the SEP button and I don’t know when he started firing.

Cooper

I fired just as you hit SEP.

Conr ad

Yes.

We came out clean as a whistle , I’ll tell

you that boy. Cooper

We fired at the same second that we hit SEP.

Conrad

There wasn’t any pitch or yaw of anything- -we just separated as smooth as a bell.

Cooper

And what I did , I—we held that on in there in direct and then switched over to rate command then a couple to 3 seconds later .

FCSD Rep

Okay, how about the—why don’t you describe the plumes a little bit here on the different thrusters and what you saw.

Cooper

Okay.

Conrad

You don ’ t see any plumes .

Cooper

You don’t see any plumes off the OAMS and all you

Well, the only really-

do is get the glow from them back there—you see

CO ►~EIDE►4TIAL

166

the glow as they fire . Conrad

And it is pure white .

Cooper

And- -

Conrad

My recollection of i t —like white li€·ht glowing.

Cooper

Of the RCS Plumes?

Conrad

No , of t he OAMS .

Cooper

Oh yes.

The OAMS .

The RCS had a little bit of a

golden color to them. Conrad

Yes .

Cooper

And—

Conrad

Plus you see on t he RCS t hrusters you see little bits of pieces of ablative material c)ming out like carbon.

Cooper

Yes.

Right.

The RCS plumes tend to come out of th,3 nozzle with a little bit of an expansion rat:lo and then just to come out in almost a column that doesn’t change much. Conrad

Yes .

It just increases in si,;e.

I was surprised t hat it didn’t expand out

this way. Cooper

Yes, I thought it would expand out .

Conrad

But it just went straight up.

Cooper

I very much thought it would fan completely out .

~O►◄ t:IDfMflAL

167

Conrad

Like a nice candle flame.

Cooper

It just goes up in just a contained column almost - in fact the column appeared t o me to be no bigger around t han t hat saucer .

Conrad

That ‘s right, if it was that round .

Cooper

Some 4 to 5 inches maybe, in diameter at the most and just went right s t raight up for a period, distance of about 4 to 5 feet I guess where it faded, something like t hat .

Conrad

Oh, I didn’t really think it went that high.

really didn’t think the thing stuck up more t han about a foot .

That i t was visible light that would

bother you. Cooper

Well , it would bother you, but I could actually detect when they would fire, I could actually see from the pitch down—I could see t hat going almost to the t op of the window on something on the order of about a 4 foot dent where you could see any line a t all.

I’m tal king about where it fades

you lmow completely.

And it’s act ually only a

couple of feet out from where the light is r eally bright. Conrad

The t hing that I thought of when first I ever

co~~FIDEt~TJM:

C QfqflDEt~TIAL”

168

saw one fire was one of these 4th of ~-uly fire cracker stand-up type bombs that you light the fuse, you know, and the thing sort of like ·;he Roman candle—it sort of spits out flame and a few sparks you know and then-Cooper

Yes, that’s right .

Conrad

That really did it .

And the other thing is that

everybody’s been talking about how bright they were at night and maybe again I was geared to see in the really, really brilliant light —I didn ’ t really think t hey were that bright—now t hey do disrupt night vision and they did disrupt t he horizon, but they.‘re not that brignt . Cooper

Well , of course you 1 ve got to recogniz,~, too , that we saw them under different conditions and the fact t hat we were expecting t hem to be very bright and we bad cabin light ing up full bright.

Conrad

Yes .

Cooper

And they were by comparison with the full bright cabin lighting—they were not as bright as we expected.

Conrad

We also went around though with the lie;hts on red there when we were alone and you were firing only

CO~‘4FIDEt~

,,,.

in PULSE . Cooper

That’s right.

We actually only bad it in PULSE.

Conrad

And really what it is—as a matter of fact , firing in PULSE and everything—you could always keep the ~9rizon in sight.

Cooper

You could keep the horizon in sight and we had the red lights on, and only we didn’t have them down dim and firing just in pulse you could hold the attitude visually very well, but when you go into any amount of RCS thruster firing you ‘ve lost the horizon.

Conrad

Yes.

Cooper

Okay.

One thing we have here on thruster firing

both attitude and translation. attitude pretty well.

I think we covered

I think our OAMS was a

very good attitude system to begin with.

think it was gradually degrading as the flight went on.

Getting worse and worse and worse and

mushier and sloppier so it was not fair to evaluate it later on in the flight because it was pretty miserable.

But the RCS attitude was beautiful .

It was really good.

It was crisp and real precise

and just a real pleasure to fly.

Translation, we

COt~~fHIDEt~~TIAb

170

used all the translation thrusters on:.y one little splurt of it on the forward, i n other words the forward firing thruster- the smal l forward firing thruster , but they were all very,· very positive and you got very defi nite die1t i nct action out of them.

And you really gc,t a feeling

of real accel eration out of those aft f i r i ng ones, I thought.

I felt l i ke you really were

really had a big afterburner lit off when you lit those things. Conrad

Yeah, man, I would have liked to have some more kinds to mess around-like turn off thruster 10 or something like that, and burn a couple of feet on one thruster because i n the s i mulator you can’t hold it in Rate Command.

Cooper

I think you probably can in the actual spacecraft.

Conrad

Well, I don ’ t know whether you can or ~an ’ t but I t hink that the difference between 2 thruster operation and 1 thruster operation is going to be apparent to you just like that and the3e guys i n F0D are making this big deal about :1aving to burn after separation from the booster and maybe only have one thruster or anything and I think anybody who has flown that thing once :Ls going

171

to have a good feel for whether he has two aft f i re thrusters or one because boy, with those aft f i r i ng thruster are firing you’re just like you ‘re flying an airplane and you put the throttle to it. Cooper

You really feel i t.

You really feel it .

Yes , it’s really got

acceleration . Conrad

And you can hear i t —it was that high speed water jet type sound , it wasn ’ t an explosive sound or a r oar or anything like that .

I t was more of a

:i swishing sound. Cooper

More like a big hose.

Conrad

Like a couple of big hoses firing back there .

FCSD REP

Okay , you say you did fire the forward firing- you checked out the forward firing?

Conrad

Just a bleep .

Cooper

Right .

FCSD REP

What did you see here?

Cooper

Oh, man.

Conrad

. Yes , well, you don ’ t , I don’t really think you really

You really see t he flames off that .

see the flames , but it throws a grea t deal more light . Cooper

It’s a l i ght rather than flames—alight more than flames .

FCSD REP

Could you see a distinct plume?

COl-4FIDE~~TIAL

172

Conrad

No .

Cooper

No , not a plume as such, but just it reially lit up . You got a lot of lighting from it .

Much more so than

you did the— It was distinct ive enough that it really made an impression on us . Cooper

Let ’ s see, the side f iring was really— the thing that ’ s surpri s i ng about the side firing wa s j ust as I— you might anticipate, if you really stop ar.d thought about it but you don ’ t get this in the trainer or anyt hing when you fire a side thrust—

Conrad

A side thrust— Yes , that was really weird.

Cooper

You really could feel that .

Conrad

It fired down , then up , then left and right then you raise up in the seat or you slide down in the seat or you go left in the cockpit or right in .t he cockpit . You know that you real l y going to do this and you-

Cooper

And you can see all the debris and evecything coming t hrough- - swish!

Conrad

Yes , everything starts going sideways .

And it ’ s

pretty funny . Cooper

Okay , we ’ re at paragTaph 10 . 3 reentry . adapter separation.

Number 1

No doubt .

10 . 3 Reentry Conrad

Yes , there was no doubt but t here agai11 one of those

~t◄ FIDEblTIAL

173

things where both Gus and John and Jim and Ed said , “Man, that thing really went out there with this horrendous bang,” and I was really spring loaded .

was waiting for a 16 inch gun to go off in my ear, and, therefore, there was no doubt that it fired , and there was no doubt that it left, but I didn ’ t think it was that loud— but then again, I think, it’s what you’re anticipating, and they had both said that they got quite a -Cooper

I think there again , you and I were keyed up to i t being a tremendous explosion—when it went off—

Conrad

But there ’ s no doubt about it that it is loud -

Cooper

There is no doubt about it—it’s loud and it really gives you an acceleration—a delta accelera tion .

Conrad

I actually heard SEP ELEC and SEP OAMS lines squibs and I don ’ t know whether you want to say whether we felt them or heard them fire, but we could hear a definite “kerplunk, kerplunk” back there when you push both of them—not loud—

Cooper

Just like the trainer.

I think the trainer is very

realistic of those sounds . Conrad

Yes, the trainer is very realistic.

Cooper

And the trainer sound is really pretty realistic

e@NnDEf~TIAL

174

of the adapter sep now .

I think they’re all three

fairly realistic of the t rainer. Conrad

And now in adapter sep you get a little acceler ation force wi th it , and you feel that .

You really feel

that-Cooper

Well , it shudders the whole thing as you come off- as you separate .

And re t r ofire to me w~s a big

surprise . Conrad

I t was a bi g surprise to me , too .

Cooper

I remember in Mercury tha.t everybody had different feelings on what retrofire felt like , a ~~d I didn’t f eel that they were that distincti ve or th~~t great a t all in my previous flight, but in this one I felt like we were on the front of Stapp ’ s rocket sledo

Conrad

Yes .

Cooper

Everyone that fire.

Conrad

We were pretty G sensative by this point , 8 days of weightlessness.

Cooper

I t fel t to me like we were just hanging on the—

Conrad

Yes .

Gordo said he thought we wound up going in the

other direction and I had the decided foeling that we pitched up and did a loop everytime one of them

•

175

fired, I had the feeling that we pitched up another 30 degrees and went streaming up that way you

know, and then another one would f ire , and I really thought we were going around a big circle .

That

was my physical sensations although the gages said we were right on the money .

But, all through

retrofire those darn re tros did not overlap . Cooper

That ‘s right .

Conrad

Especially 3 and 4.

They didn ’ t .

Number 1 .

As a ma tter a fact, there was

enough of a de lay—

”

176

Cooper

Let ‘s go through these now. on time.

Number 1 fired exactly

Boy, right on the money with ‘I’R .

were right on the money.

Every clock we: had in

the spacecraft was just reading right O when it fired.

No delay or anything anywhere.

Just

beautiful.

Number 1 was still firing when number

2 started to fire. Conrad

That ‘s correct.

Cooper

And there was no off-set whatsoever from. number 1 and number 2 .

Conrad

That’s right.

Cooper

Then number 2 had finished firing for a definite delta time period before number 3 fired.

Conrad

That ‘s right.

Cooper

Then number 3 fired and had an offset to the left—to the left—ye s to our left which was not bad and I think they had r times that am::runt of off- set it had and still hold it with th~ RCS , no with the rate command. doubt in your mind. powering.

No problem at all.

You were way more t han over

You must keep it glued right t here.

But then number 3 finished firing and then there was an even greater delta time- -

177

Conrad

That was a period of time that I -

Cooper

Before number 4—

Conrad

I thought we weren’t going to get number 4.

FCSD Rep

What would you estimate the time?

Conrad

Well, I’d say it would have been a full second .

Cooper

Boy, I think it was at least a full second.

Conrad

Time up there is going to seem like—

Cooper

Time—yes .

Conrad

I t may have been shorter than that—but there was a definite delay.

Cooper

I 1 m sure that our time sensing mechanism was overly tweaked at that period of time and we probably were overly sensitive to it, but there was no doubt I don’t believe there was any doubt , and we both arrived at this conclusion independently too-that number 2 came in at the right sequence on number 1 and then there was a short delta time and then number 3 fired and then a longer delta time and number 4 fired.

FCSD Rep

Okay, how about the visual sightings duri ng thi s.

Cooper

Ma.n- -

Conrad

We were I FR completely the cockpit lights up full white, pitch black and—

178

Cooper

And the whole window area was completel;r obliter ated by flames.

When the retros go off you’re

just in a big barrel of flames—because the whol e thing is just covered by flames. Conrad

I wasn’t even aware of that.

I didn’t (~Ven—

I ‘d have said that we didn ‘t see any flume at all. Cooper

Well , we had everything at full bright-••

Conrad

I guess I had my eyes locked on the instruments-

Cooper

Well , I did , too , but I also was going to look and see what it looked like out the window there and I noted that everytime one of them went off you got tremendous flame coverage which surprised me because I didn I t think you would .

I thc,ught

maybe you’d see the glow from it but I lad a distinct feeling that the whole— that tl:.e whole flame expanded to the point where you felt like it—maybe you just felt like it was so bright it just lit up the outside that much, but I had a distinct feeling that you really had flames all over when they went off. Conrad

Really that ‘s the high light of the flight in my mind is going down through that— watching that TR clock count down and going through TR - 1

minute to TR+45 seconds throught retro- jet .

You

seeing that sequential system go amd

know

everything work-

just like it was supposed to,

and the checkoff list go

and everything: B())y,

we were really spring l oaded on that. Cooper

I know Pete had made some comment , “Well , things have continued to fail and I just hope that is one that doesn ’ t . ”

Conrad

I had lost faith in sequential systems s omewhere along the way.

We had all the emergency systems out though,

and we were ready to fire it any way we had to . Cooper

Yes , we had gone through our little emergency retrofire and our emergency SEP ADAPT and all this. We were all set to go on those , and I think we’d have been in rea l good shape even if they hadn’ t occured .

Retro- pack jettison —

Conrad

Straightforward.

Cooper

We held retro- attitude , waited on the light , armed thereto- jet and when the light came on Pete toggled them and off they went 11KapJunk 11 •

They sounded just

like in the simulator . Conrad

Again we didn’t see anything.

It was pitch black. Had

cockpit lights up full white . FCSD REP

Now, you turned around, and you saw it burning up.

~ CiQ~~4fiOD~~TlAi

180

Cooper

No .

Conrad

No .

Cooper

After we started reenter ing we—

Conrad

During

the

reentr y and it was way , way behind

us , but I did see it—now , I say the retro pack- it could have been the adap t er burning up .

don ’ t know which one it was , because it was so far behind . Cooper

There was some object way behind .

Conrad

It was some object , a large object , ree:~tering behind say?

but it must have beer—what would you

5 , 6 , or 10 miles maybe?

Cooper

Oh , yes!

Conrad

I t was way up the path .

Cooper

I’d guess a good 5 or 10 miles .

Conrad

And it was up in the—let 1 s see, I was upside down , and it would have been—coming heads up—it would have been in the upper left- hand :lide .

other words , it was reentering to our south and above us .

It was entering on the south side of the

orbit , and it was sli ghtly above our en•;ry and you could see our trail clear back to it .

You could

see our plasma jet went way , way back there .

EOMFtDEl-Ttl don’t know what it wasp’whether it wa s smoke or what it wasn’t fla.rne—you could definitely see it trailing right along side our trail just like we were leaving a con . Cooper

Yes , you could see our con—it was kind of a light color .

I wouldn’t say it was a flame color—it

was kind of a light color. compared to everything else. Conrad

We were looking at this in relation to what nobody else hadseen it to .

We were still looking at this

down sun relatively nebulous horizon that you have. We were looking at it ourselves , a trail back there in the terminator. Cooper

Into the dark .

Conrad

Yes .

And that ’ s another thing.

A very important

point here— no kidding, saying this spacecraft’s i n s unl i ght doesn’t

• mean anything?

That ’ s ani ght retrofire.

And we didn’t have a definable horizon to fly on until we crossed the Mississippi River• .

That ’ s

way in the heck down the pipe on retrofire, because that terminator is nothing. Cooper

One thing I ’ d like to add here- -I really

think a l l

.of us always sweat~d night ret rofire and it wa s a pi ece of cake.

182

Conrad

It really was .

Cooper

However , if you don ’ t have full instrunHmt panel, I ’ d recommend you forget it . have an 8 ball and

Because i:~ you don ’ t

think , you could hcndle them

in direct with no problem. FCSD REP

Do you think you nee~ both the rate gyrcs and the platform?

Cooper

I do .

Yes .

I would strongly recommend that for a

night retro you not try them on purely rate gyros because you just—even the little-Conrad

And the reason—

Cooper

The RCS a ttitude system disrupts your night vision so much out there that getting all squar =d away for i t— j ust about the t i me you I re getting right in to retro attitude there if you have to f:ire a thruster or two you ’ d completely lose you attitude-

Conrad

I think the other big thing is tha t that is absolutely the world ’ s biggest “vertigo gi.ver” , because you are really g sensitive and when those retros go off if you don ’ t hav11 the whole smear of

00MFIOE~~TIAl’

183

instruments- -like I said I was watching the i nstruments and they were sitting right dead center.

]ordo had that t hing pitched down

30 degrees and we didn ’ t hardly over 2 degrees off

that darn retro attitude.,and I wa s convinced we were doing a loop— even watching the gages .

That

is the worst set of vertigo that I ever had in my life . Cooper

And I had the dist inct feeling that I had just lit off the biggest after-burner I ’ d ever haa a h0~d of and was going back straight west juat as hard as I could hold on .

Conrad

But ,

even with thi s better window definition , when you crossed the terminator from day to dark or dark to day there’s a very decided confusing area in there where you have absolutel y no attitude reference at all out the window.

I can’t figure how you

get all these odd refl ections in there.

There’s

a period of time when everything just gets completel y jumbled and it’s a real dim gray area there you ’ re going through just for a few seconds where you have absol utely no visual reference at all .

You ’ re

for a bank lef t 54 , a bank r ight 68 , which was a change of 1 degree from 53 and 67 .

He gave us

That was

Okay, spacecraft oscill ations—

FCSD Rep

Could you tell anything visually?

Conrad

Man, that thing was like a rock coming in!

I ‘d

been hearing about 40 degree yaw oscillations and the drogue and everything else.

I f we had

anything over 5 degrees- -maybe it is jus t me , but I don’t think we had anything over 5 degrees. Cooper

Let’s start farther up in the reentry.

After

we got to 280 K, I was switching back and forth at this point from r ate to attitude.

I would

switch back to rate, and when I ’ d see we had a little rate build up , I ’ d tweak it , and then back to attitude and hold my attitude on the attitude needles.

Then I ‘d wait just a few

seconds and switch back to r ate and t weak out the little rates set in, and go back to attitude- back and forth in this f a shion.

On single-ring

direct, I had more control authority, initially,

190

than I needed.

I had to be very careful to just

put a little teensy tweak in to damp the rates. Later on, as we got on down, maybe half way through the g pulse area, the rates began to in crease in amplitude and in frequency .

J still

was able to handle them very adequately.

problem at all on tweaking the rates out on pitch and yaw.

However, at about this I1eriod

of time, it began to take so much time t o switch back and forth from rate to attitude and get the rates damp that I was getting concerned about the math flow guidance in here and making sure I stayed on it.

At this point then, probably half

way through or somewhere on down through the l atter part of the reentry, I just switched over to the ACME position and allowed the RCS rate command t o damp the rates .

Then, I wouli reach

over and check the rat es once in a while to see how it was damping.

But, then, I could concentrate

on purely attitude .and just fly this same single ring attitude control. attitude control .

It left me plent,v of

was just keeping it damped to zero.

We -weren ‘t

firing thrusters too overly often.

You could see

them fire now and then , but it wasn’t a great task for them to fire at all .

I really thought

the whole reentry was quite stable and at no time did we have a;ny real oscillations . Conrad

Somewhere in there Ring A ran out of fuel .

But

I am almost convinced that-Cooper

Well , let me say r ight here now way flying the thing .

fuel as long as I was flying.

Pde .

Ring A didn’t run out of

We s till had control .

Now

you are talking about down after drogue deploy. I ’ m talking about during reentry.

Until the time

that we went to dual- ring RCS , we still had fuel left in Ring A. Conrad

Yes, I know we did .

Cooper

Okey, I just wanted to make that clear on the record .

Conrad

It ran out somewhere below 65 ,000 f eet .

Cooper

Yes , by those f igures you got yesterday , it looked like we still had fuel in Ring A sometime af t er we br ought Ring Bon, which was at 60 , 000 . Right?

C:et<tfilf)Et◄l l.._

192

Conrad

That’s right .

You get an idea of how much fuel you

use because Ring B was tested but never used until below 65 ,000 feet; we shot 80 percent of the f uel out of it on the drogue.

So , it iB no

surprise to me that Ring A ran out of fuel . There is no doubt about it that Ring A ua.s still running, unless somebody shows me otherwise on a traces , at least past drogue deploy.

It was run

ning until at l east we got Ring B running . Cooper

I really firmly believe, based on what we tried on here and my feeling on the thing, you could shoot two or three orbits of attitude control and align ment and the whole smear of r e ~rofire ar.d the whole reentry and everything on one rin€’ with no problem at all .

Conrad

Now , let’s look at another thing .

When you are

at drogue deploy , we were on rate command and there was a high frequency, low amplitude oscillation, but it was well outside the r ate band.

So , those

thrusters went to steady- state firing . Cooper

Yes, they did .

Conrad

They were firing full blower all the way, trying to damp .

And they did.

They did an excellent

.193

job of keeping it damped .

We were steady as rock

coming in there . Cooper

Of course, this is the way to do it.

Conrad

They were firing all the way, and it doesn’t surprise me at all that we used all that fuel out of Ring B.

But Ring B, I know , wasn’t put on

until the drogue was out.

And I know t hat Ring B

had no fuel taken out of it except to test it two orbits back.

There are some 33 pounds in

Ring B, and there was 4.9 oxidizer and 4.6 fuel left in Ring B.

So, we shot almost 25 pounds of

fuel on the drogue. Cooper

Conrad

Which is fine .

You might as well use the fuel up

at that point .

There’s no sense in saving it.

Again, this tells me that up to drogue deployment you might as well take that reentry rate command and throw it away because the pilot i sn’t going to accept four degrees per second anyhow. going to d.Q.mp before that.

He is

So , you might as

well use the wire for something else .

Use rate

command, and if you fly the reentries just like that , you’ve got more than adequate fuel in Ring B to poop it away on the drogue and insure

194

yourself a nice steady ride.

We never :Jaw a:ny

thing that approached over 5 degrees oscillation. Cooper

The nice thing about the control system is that i t is a simple matter to switch back and forth between direct and rate command in the uystem that we had set up .

If you are damping and the

damping gets to be t oo much of a t ask, or it gets more than you can damp, all you do is switch over to the ACME position on this one switch and i t will damp in the rate command .

In that rate

command, you have really good damping.

You might

as well have a system that will damp it right down to a gnat ’ s eyebrow, and then you can switch back into direct , concentrate to what you are doing , and switch back and forth if you want to . Let’s see , drogue-FCSD Rep

Di d you get enough of an oscillation dw·ing reentry?

If you looked out the window . _•as there

enough trailing you that you could pr obc,b ly damp by looking at this?

Was there any possjbility to

do this? Conrad

I don ’ t think the spacecraft is that un~table .

Cooper

We didn ’ t have that much oscillation .

195

• Conrad

I don’t think you have to worry about Lt , to tell you the truth.

I really wasn’t aware of any

oscillations at all.

Gordo says he was damping.

For all I know we rode in there free. Cooper

He speaks highly of my damping.

Conrad

The first time I really noticed anything was when we got on the drogue , and I didn’t have a whole lot to do. but to look out t he window.

Cooper

There would have been some oscillation, but it would be kind of interesting to ride one down and not damp it, to see how it would do.

really doubt if you’d get very large amplitudes or very much-Conrad

Not until you get down there below a 100 ,000.

Cooper

I don’t think this is true of a rolling reentry. That’s why we never were in favor of a rolling reentry.

On the simulator the thing goes wild

on a rolling reentry.

But , I think, a s long as

you hold a steady bank angle , whether i~ is full left or 90 or whatever you hold, I think the thing is really stable. to me.

It sure felt that way

It felt to me that it is a good stable

vehicle. · Now at drogue deploy— I very deliber ately deployed the drogue at 70 ,000 feet.

You might put down that I was reading t:1e check list off, and I called stRndby for 70,000, which is our point to put the second ring on HCS rate command, and we were going to put Ring Bon .

s aid stand by for 70,000, and away went the drogue. Cooper

I reached down, uncovered the cover on :.t, and punched it out right at 70 K.

I might Hay here

that the drogue went out beautifully, it squidded a couple of times—a typical supersonic drogue f ashion.

No hard squidding.

Conr ad

I ’ m not sure that it stayed reefed.

Cooper

Yes, it did .

Conrad

It did a couple of gyrations up there . really sure what it was.

Did. it?

I wasn’t

I don ’ t think it stayed

reefed for 16 seconds. Cooper

Yes, it did.

Conrad

It looked to me like it flew out and opened.

Cooper

It came out and opened in the reef condition.

It stayed reefed for 16 seconds.

That was that squidding you saw .

I t opened in

the reef condition and then it squidded 3bout three times in the reef condition and then dereefed fully opened .

It was as stable as a roc:ce.

I fully anticipated some of the lines we:c-e

.,§Q±!f lDEt◄ TtAL •

And

197

probably booken, and I began to look at them. They looked good.

I decided, well, it wasn’t really

any problem, even if I had broken the lines.

All

I had to do was reach up and deploy the emergency main deploy if it departed, and we were still in good shape, so—no problem on it.

As a matter

of fact, the combination of when the drogue went out and the RCS left us as stable as a rock . We just came right straight down t he glide slope and I don’t think we had any oscillations of any kind all the way down, other than these very very minor little higher frequency ones t hat felt like vibrations off the drogue lines. Conrad

There seemed to be more interaction between the spacecraft and the drogue lines than anything else.

Cooper

Right.

At the time that we came to the main

chute, when I pickled off the main chute, it came out completely straight; we didn’t oscillate or swing on it at all. Conrad

Let ‘s backup one second .

The best calculations

of m:ic.e and men were completely wrong though . At 50 K we went on with full repress and o high 2

198

rate .

And past 27,000 feet that cabin :lndicator

hit zero fas~er than you could say Jack Robinson . That thing came off the peg and I had to go back to the old procedure of-Cooper

Snorkel open up .

Conrad

Snorkel vent open , and recirc at 45 deg.eees. We didn ’ t seal it up again until 2,000 , so that didn’t work.

Cooper

Then, at 10 . 6 the altimeter and the barostat light were exactly right together.

I punched the

main and it came out reefed.

It held rnefed

for approximately 12 seconds .

We were nxactly

straight, no oscillations or swings or gyrations on the chute at all.

I n fact, we were flO stable

on the chute that in the reefed condition the skirt was exactly symmetrical arou.”1.d thn bottom. There was no breathing to one side or anything. Conrad

I think that is another thing that speaks highly of this rate command business, even through we shut it off at 30,000 feet.

By that time, we

were well slowed down, and there was no big os cillation, left on the drogue .

So the 1•est of

the ride with no system was free .

Now, when that

199

chute deployed we weren’ t even swinging or anything. Like Gordo said, boy, when tha t thing came out of the reefed condition, it was perfectly circular around the bottom.

We looked at movies of these

things and we’ve seen them collapsed on one side, billow out, and collapse, and everything. didn’t do that .

That chute came out, stayed

perfectly circular.

Whenever the number of seconds

went by, and the thing dereefed, it dereefed per fectly circular.

It never breathed, never

oscillated , never swung or anything. Cooper

And we never turned on it either.

Conrad

We never turned or anything.

The only oscilla

tion we got the whole time was when we went to two-point. was it.

We got the see-wawing action.

That

We went straight into the water.

The

chute almost landed on top of us. Cooper

Okay, on Rand R separation—we might cover that after drogue deploy— it is just exactly like it looks in the sequences .

You see all the whole

They visually got our thumbs up signal with

The only abnormality was that after

We were transmitting coming down on

the chute, on the main chute.

We made two steerage

transmissions and counts, and AIR BOSS received these and acknowledged them and got the clears on them.

After we were on the water, he apparently

was not receiving us. Conrad

Okay, now, I found a mistake, and that is my fault on the HF antenna.

I went down through the check

list but I read this one item wrong. three squib batteries off. No . 3 squib battery on.

I had all

I should have left the

The antenna goes up on

the common control bus, so that is my fault that the antenna didn’t go· up. Cooper

But, I thought I remembered when you put those off was after we had already gone through all this.

Conrad

Well, I’m not sure that you are not right there, but I still made the mistake of turning all three squib batteries off.

I’m sure that if it doesn’t

go up with the squib batteries on, then there is something wrong with the antenna, but if it goes with the squib battery on, why it was my fault . Cooper

But , in defense of Pete on this, I ‘m almost sure that we had already gone through all the sequence

202

and said, okay, let I s go through and re1:,lly see what we can power down here now.

We had. gone

We had gone through a sort of s econd power

Yes, you are right .

Cooper

So, I’m kind 0f inclined

to think that was not the fault of the Bquib bat tery being off. Conrad

That’s all there

It sure did make it easy.

Very briefly we would like to cover post-landing. First of all, we had ideal conditions.

It was

early morning, the air was cool out on the water. The wave condition was, at the worst, 2 to 3 feet easy swells.

Almost calm conditions, low

wind. Conrad

Let me add one thing on that.

We sat there for

4 or 5 minutes in these 2 or 3 foot waves, and every once in a while a wave would wash over the top of the spacecraft.

I think you want to be

real careful, and I still say-Cooper

Not over the top, but they could wash into your window.

Conrad

Right over the window.

Cooper

Your window was the down window.

Conrad

But it looked like it would roll up on your window.

Cooper

That’s right.

That is a good point.

Conrad

Even on as calm a day as that, boy, don’t ever open those hatches unless it is a dire emergency until they’ve got that collar on there.

Cooper

I agree.

Conrad

I could see that thing going right straight to the bottom.

Cooper

I agree.

Pete and I both were in complete agreement

on this. Conrad

It was as calm as you could get out there.

Cooper

It was a beautiful, calm day. point is exactly valid.

And even so, his

I think that if you open

up even the left hatch, which is the higher hatch, there would be an occasional wave which would throw water into it.

I think opening those hatches

out there, even with the splash curtain, is a real bad situation, unless you Just absolutely have to.

You are risking really filling it.

Of course, I think you can get them closed and shut down if you start taking water on board, but there is no sense in getting the whole inside all smeared with salt water.

However, we were

perfectly cool inside with both suit fans operat ing when we got the repress off, the o2 high

rate off, and both suit fans back on the line. We sat there and we were perspiring vecy lightly, but the spacecraft was cool; we had cooled it down prior to reentry as cold as it can go.

It was

50 degrees cabin prior to retrofire and 50 degrees suit loop-Conrad

We had thought when we hit the water if we were going to have any wait —and it was apparent when we got down there we were going to have a wait- the smartest thing to do is to get out of the suit.

It became real apparent that the smartest

thing to do was to stay in the suit and get the snorkel open, get the both fans running, and the cabin fan running. Cooper

And this was the answer, because we were really cool in there.

There was no problem.

We got our

helmets off, our glo-ves off, and our neck dams on so we could recirc through the suits good. was nice and cool in there.

No problem at all.

We could have sat there for hours on end if we really had to .

No problem.

Of course, there

again, we want to emphasize t hat we were there under ideal sea conditions, and I am sure that

@OMFIDEl>~TI-Al

206

that little spacecraft could get mighty nauseous if you really had rough seas. Conrad

We did have just a t winge of RCS fumes in there . We had sealed it off at 2, 000 feet and it had only bui]

up to a pound by the time we got en the

water, so that secondary o flow rate ar..d o2 2 high rate is just not putting out a hecli: of a lot of flow. Cooper

But it helps.

I think you really had t o really

sniff to—you had to be hunting for it to smell the fumes. Conrad

Once we got the snorkel open again on the wat er and had the cabin fan and the two suit :~ans running, the smell disappeared shortly thereafte::.- .

Cooper

Yes , it was nice and fresh.

Conrad

I t got to be nice and fresh in there.

As Gordo

says , we wer e perspiring lightly but ou~ best bet there was we were getting good flow in the suits from the t wo fans with the snorkel open. Cooper

I might recommend at this point for later crews that this~ a good point to take that doggone bl ood pressure bulb and pump up the water system and drink all the water you can drink right there .

207

Because once you hit the carrier, the medics aren •t going to let you drink for about a 3- hour period while they run all their little diddies on you.

They don’t care how thirsty you are or how

bad a situation it is .

So, I would recommend that

you just fill up with water right there. Conrad

The most uncomfortable and the hottest we got was in the nelicopter ride back, which was 35 minutes. It was hotter than blazes in that helicopter. We still had the suits on.

We could have gotten

out 0£ them, but we had gotten out fairly dry to begin with, and we just decided to-Cooper

We decided, as a matter of principle, we were going to arrive on the carrier with our suits on.

Conrad

We arrived in uniform on the carrier rather than in a bathrobe.

Cooper

Besides that, we didn’t have patches on our bath robe.

Conrad

Right.

Cooper

Okey, thatls all I think of.

No, once the hatch was open and started open, then it was free.

Cooper

For some reason or another—that is the first time I’ve seen it like that when you couldn’t get it open.

Conrad

I checked mine and it worked okay.

Cooper

We mentioned before, but we might menti,m again that when the reticle wa s exactly bor esighted on some object like the moon or a star so was the Questar lens.

It was right on the money.

Conrad

Yes , r eally good boresight .

Cooper

And t he radar was also right on .

Do you want

213

FCSD REP

Why don ’ t we wait?

Conrad

We did that portion of D- 1 that was … Then the next D- 1 we did was Mode 2.

This was done on Venus

at 02 days 13 hours 00 minutes .

We took 4 pictures

of Venus at l / 30th of a second on magazine 11 which was the 8443 IR Film.

It was taken through the

Questar lens visually with reticle tracking. me check the book to see if that is all .

Let

D- 1 ,

Mode 2 we did at 02 days 13 hours 20 minutes, on Alpha Centauri using magazine 9 which wa s 3401 Film. We used the Questar lens , took 4 pictures and that completed the D-1 Experiments.

Let ’ s run through

the updating techniques and communications procedures that ar e used with the other experiments and I ’ ll only cover them once and that ’ s this time .

We send

up the title of the experiment , the GMT of the experiment , the sequence number if required , a Mode number if required and then any other require ments went in the remarks section.

Things such

as pitch , yaw , up , down , filmspeeds , and delta times or anything else went in remarks .

I think

that this procedure worked extremely well .

Ther e

was never any confusion on our part as to what

Gelat,JOENltAt

• experinent or how it was to be done . Cooper

The only caution that we might throw in is right here—

Conrad

Stick to sequential times.

Cooper

Ri ght, stick to sequential time exactly so that you have running sequential time.

You can :{eep track

of all the great number of things that they are sending up .

They might also consider wi1at—equipment

set up and stowage problems you have wh,m they ’ re sending these things up.

We had a great deal of

equipment shuffling to do there. worked out fairly well.

In general , it

All the equipm,mt worked

extremely well except 35mm camera which jammed several times on … . Conrad

Okay, now the reason it jammed was that photo event indicator,,which st.raps on the film tran:,port adapter cable,,was too long when t he trigger was squeezed . That had a tendency to jam the camera mnchanism , and I had to back it off out of the thrnad zone so that it wasn ’ t tightly in there. continue to back itself out.

In zeJ~o g it would

of pictures and then it wouldn ’ t take a picture and I woul d have to reach down and screw it in.

cCQMAO£MIA L

215

would screw it in too tight so I would get one more picture off and then it would jam, and I would back it out a little bit.

We finally got to where it

worked pretty good . Cooper

But this still is an equipment discrepancy that should be—

Conrad

Yes , and equipment discrepancy and it a lmost cost us a couple of good pictures .

Especially, when

we hadn’t found the ship about four times and all of a sudden the camera was jammed… . wall light fit in there .

I might say here that this is D- 1,

D- 2 , and D- 6.

D-1 we got, D-6 we got quite a

bit of , and D- 2 we did nothing.

What we are t alking

about is the camera equipment associated with D-1 and D- 6 . Cooper

Acquisition Techniques— They varied.

Acquisition

techniques varied depending on whether it was a celestial or ground target .

Again we can’ t

emphasize ~nough to do experiments where you have to point to certain places to find things the only way to do it in a professional manner is to have a plat form up and use the pointing angles.

It makes the

task a thousand times easier and it eliminat es all

21 6

this sloppiness .

If these experiments are worth

taking platform time and power to do . Conrad

We’ve got to say here that there was so much diffi culty in finding these things and getting organized that we made onboard decisions to drop this track ing technique and we used only one method .

We both

looked for the target and when we found it, if we found it, I got Gordo pointed in the right direction and he put the reticle on it.

From then on , he did

the tracking and I took the pictures .

I ‘d coach

him if he was off at all by looking in the lens . We never t ried the technique of me flyi::ig and taking the pictures at the same time .

We didn’t because

the majority of pictures that they asked for in D- 6 were Questar pictures.

I would never have been

able to find it if we were off the leas·~ little bit because the pictures that they wanted f :l.lled the whole Questar l ens .

We found that the lioresi ght

was perfect so rather than mess things up and we

- Things were getting worst .

To make 11ure that we

got the pictures , we dropped thes e different track ing modes and we used the same t echniquEi everytime .

Gordo tracked it in the r eticle and I coached him if he wasn’t right on fo~ he picture.

c_Qb4f10Et’4TI L

I told him

217

where to go and I took the pictures; and we used that consistently .

Now that’s a switch from what

they wanted but I think it bought them some. still proves that you can do the job. has too small a field of view .

The telescope

I recommend if you

want the man in the right seat to track and fly them he should have a reticle on his side .

Then he

can track with the reticle and not the telescope. He tracks with the reticle and he looks in his view finder just to make sure that he’s got the picture where he wants it in the view-finder . Cooper

Comparison of operational modes .

Conrad

We covered that.

Cooper

Voice recorder usage.

Cooper

We used it while we had it.

What about your D- 6 logs?

Conrad

This D-6 log is pretty long.

Do you want it all?

02 days, 13 hours, 41 minutes , we had 012 which was

218

Monterrey, Mexico.

It was covered by elouds , so

we took Tampico instead.

We took two pictures.

02 days, 15 hours, 16 minutes, 59 seconds, they asked for 020 which was James Connally AFB at Waco, Texas . It was obscured by clouds so I t hink we got the Dallas Air Naval Station and it wan sort of hurried but I think we got five picturHs.

The next

thing they asked for was on 03 days, 11; hours,

37 minutes , 28 seconds , we got our fir11t missile. I got five pictures.

I won’t guaranteo whether the

missile was in it or not.

Shortly aftHr that time ,

we got seven of Holloman .

I was so tickeled to see

the sled down there that I shot 6 pictures instead of four.

At 03 days, 16 hours, 44 minutes , we took

five pictures of Bergstrom.

On that same pass, we

t ook four pictures of the Cape and tha·; 1 s when we were tracking with radar . Cooper

Yes .

Conrad

Then they gave us a target on 04 days , 12 hours, 08 minutes, 13 seconds of Los Palmos and we got four pictures in the mode that they wanted.

04 days, 12 hours, 24 minutes , 02 seconds, we got Mozambique .

I 1 m not sure how well we got it, but I

took six pictures down here so I guess we got it

219

pretty ~ell.

At 04 days, 13 hours, 29 minutes I

got Savannah. Municipal even though they were asking for something else and that was covered and then I t r ied to get them a picture of this Blantyre Airdrome at 04

days , 13 hours, 58 minutes, 50 seconds and

all I got was the terrain around it, because i t was covered by clouds .

I t ook a couple of pictures

down there anyhow, because this was IR film , and I thought they might want to look at Africa.

04 days, 15 hours, 56 minutes , 53 seconds we got W!iite Sands again on a 424a.

I got 5 pictures .

Then we got the best one of all 04 days, 15 hours, 04 minutes, 40 seconds .

We got 6 pictures of the

USS Lake Champlain. Cooper

Let me interrupt one thing here .

I think you said

15 hours on White Sands . Conrad

Did I? White Sands was 14 hours , 56 minutes , 53 seconds .

Then we picked up the California missile

on. the .next one. of that.

I don’t think I got any pictures

We saw the missile real clearly but Gordo

didn ’ t get on track so I don ’ t think we got the missile in the picture- - Every one of these pictures that I mentioned are Questar except the Savannah Municipal which was on a 200 mm.

ee►◄ rlDE~~TIAL

Then we came up

220

with object 65 which was this small island off Brazil and that was 04 days , 16 hours, 51 minutes, 25 seconds and we have four lovely pictures of the first island which is 120 miles above the corr ect island .

We have four more pictures of the correct

island .

We finally found it .

Cooper

Here is the map problem that we remarked about earlier .

Conrad

Here then i s the only one that I really messed up. 05 days, 11 hours , 43 minutes , 41 seconds was the Cape radar test, and I had the darn lens on l/250th and I should have had on l/30th. 4 pictures will come out.

I don ’ t think those

And that ’ s it for D- 6.

FCSD REP

You mi ght mention here the tracking of these missi l es?

Conrad

No strain.

You ’ ve got to get on them right away.

When Gordo finally saw it the second time it wa s just to far away to get him in PULSE,

When they

come r ight of f the pad you can see them all right . It gets harder the higher they get. the second stage.

Especi ally

I got the first missile al l the

way to first stage burnout.

Then I was behind hi m.

I kept seeing a piece of the contrail here and ther e but I really didn ’ t catch up with him until he passed our altitude .

Just about that time he

burned out again and then he was gone .

We could

have t r acked him through second stage.

If you

are going to get hi m on IR you better get him coming off the pad because after that you can ’ t follow them very well with the naked eye.

We had

two entirely different lighting conditions . The first day we had them against the clouds and the second day we had them against the land and water. Cooper

We had him against that one string of clouds. We lost him going against those clouds .

If you

had a solid land water background I think you could fo l low him the whole way without any problem . Conrad

The f irst day he didn ’ t come up out of the clouds but he did to us.

You know it was clear at Vandenburg

but the clouds were close enough to cut off our angular view. Cooper

First , we saw him when he—

But we had good lighting conditions in spite his being above the clouds.

The lighting wa s such

that we could foll ow him real easy. Conrad

But the second day I was looking right at the pad , and I saw the engine light .

There ’ s no two ways

about it, I saw the engine light or whatever the fire was coming out of the hole .

I don ’ t know how

they fired them , but f r om the time that flame was

photometer in the window whenever we went by the S- 8/D- 13 target — we got t hose measur Eiments , but we 1

didn. t get the last day photometer mea~iurement be cause we were in drifting flight and di dn’t have the fue l to set it up.

But I don 1 t think the wi ndow

changed. Cooper

I don ’ t either .

Conrad

Yeah, okay.

Cooper

Let ’ s see , ·the vision te ster , I thought worked very • well.

No problem on it - - everything “·orked just as

advertised and we did run it just as we had agreed to run it and was scheduled to run it .

I n fact, in

creased our numbers of runs on it later on. thing went fine on it.

Every

I sure noticed a variance

from day to day in our perf ormance

back and f orth,

back and forth — it would seem to me like we — and I think thi s is probably a function of how much we

•

OtFIDE~◄ llAL

235

have been looking out the window -Conrad

Yeah, I think you hit the nail right on the head with that one —

Cooper

Because once you have been looking out the window for a while , if you come back in and do anything for a while until your eyes kind of got set tled down was very difficult .

The M- 9 — it ’ s not the M- 9 vision

test — it was the M- 9 vestibular functions tests of we ran that just as we had said we would run it

we held our heads alined with the

headrest , as straight as possible, and turned the thing on - - I took mine in my right eye, Pete took his in his left eye , so t hat I could read along the side of his and he could read along the side of mine . I alined with the top of my instrument panel which is offse.t by some 30 degrees, or so , and I assume that Pete alined with the top of his also.

And we

would spin the dial and then while looking in there , aline with what we thought was the parallel alinement with the top of the panel and then say read, and the other man would read their reading or would record the reading down then, and we di d this five times to get the readings — enough said for that .

I just

will say that I — my personal opinion on this thing

ct>J,FK) E►~T I,._.

~~t◄ FIDE►4TI~~

236

is that it was put in here politicall y , that it was ill planned, ill defined , and is a worthless experi ment .

I hope someday somebody will have the courtesy

t o check some of these things out more thoroughly . Ground observati ons - - we can’t even say about the Austr alian site - - the Woodleigh sit e because the weather was such that we never got a look at it - t wo times we could have gott en a look at it, t he weather was very bad over the area and one - Conrad

We saw the smoke so clearly though ,~ and the weather was so clear that I could sort of put that in a category with Yuma, you know, I just wished we had seen i t

Cooper

Yeah, I do too .

Conrad

That darned Laredo site — even when we saw the smoke - - the contrast ratio was down so much on the· target outlines

Cooper

Yeah

Conrad

That we had a great deal of difficulty finding the target .

Now Gordo found them a couple of times when

I didn ’ t even f ind them even looking right at the right spot and I — when I ‘d find them , why I ‘d be too late — I mean we’d be already at the Nadir and going away from i t and by that time , we ‘d usually be

co~~FIDE~~TIAL

237

in rolling flight because of the tracking involved and the couple of times we saw the marks , you ’ d be messed up trying to decide whether it was the 1 , 2 ,

3, or 4, just from orientation. Cooper

Well, here again, we were trying to salvage a little bit out of drifting flight and I realize why we con tinued that experiment where we could and doing what we could, but it ’ s almost worthless to try and do anything of this type if you don ’ t have attitude control systems —

Conrad

And a platform

Cooper

And a platform

because you have got t o be able

to get powered up , you have got to be able to have pointing information, be able to get on the thing at an early enough date to get your angles right and to get all set up and to be able to control the· spacecraft so that you can take the right look angle . When you are trying to climb all over one side of the spacecraft, peer out the back corner of the other window and one in one another ’ s lap, one peering out of one window and one out the other and there ’ s just a mess and it doesn’t do the experiment justice and it doesn’t do us justice .

If the experiments going

to be done at all, it ought to be done right and

@0 ►4FIDE~~TIAL

238

here again , I say I realize why we wer,= trying to sal vage what we could out of a bad sit 11ation but it didn 1 t really do justice to the expt=riment .

never r eally once really gave the expe:C’iment as far as the ground observation, a really fa:Lr chance. And the one time when we really did give it the most fair chance, when we did have attitude control , was extremely bad weather — the haze was ·)ad — it was j ust about like

the

day when we went over it in

the airplane trying to do those observations , it was a low sun angle and

haze and the vis:Lbility in the

area was not real overly good .

Pete ’ s already

covered the window measurements checkli st .

I think

that t his whole _experiment was very well laid down and very well prepared for and that the people con cerned with this experiment did a real fine job of • it -Conrad

I have to make one comment though , I think that the target size was small enough such that the target itself , although it had the high contrast ratio with the surrounding background , that they were looking for , you know so it would stand out, was lost in the acquiring — in other words , th3.t thing was designed for our close overhead work to see it , and therefore,

EO~~◄ FIDE~~◄ TrAt

239

besides the smoke there was nothing else to — in a contrast nature — to attract us to the target area Cooper

That ’ s right.

Conrad

And that — the problem was acquiring it — we were always in the process of acquiring but by the time we acquired it, we were already overhead where we should have been making readings .

Cooper

Yeah, I think that they might do ~ell to put some big colored panels out or some type of something that would be more distinctive

Conrad

Let ’ s (Say this — the times that we saw the ships, the time we found the carrier, we had the carrier wake in sight for 500 miles even though we didn ’ t have the ship in sight and we were bor esighted , tracking, ,spacecraft pitching down keeping track of that thing when we got close enough

to actually

see the aarrier with our naked eyes, why it’s because we had been tracking and looking and focusing right in the right spot all this time .

You can ’ t do that

with that type target , and this was the thing that I was afraid that was going — they’ve tried to control everything in this S~S/D- 13 experiment measure the atmosphere , they have measured our eyes, they have made the targets the right size , but they

240 left out the one thing that reall y made — just like being in the desert — you are flying along out there over the desert and a very , very small ·;hink road s t ands out and the reason it does , is because it ’ s got the r i ght contr ast ratio .

You can put a 6 foot

road in brown in a brown field and you ’ r e not going to see it from 100 feet in the air. whole trouble.

And t his was . the

The targets were to small that their

contrast ratio didn ’ t help us acquire. experiment was really a good one .

I feel the

I re~lly feel

badly about not getting the data , but ~1 opinion hasn ’ t changed from before flight — I ·,ras worried before flight that the contrast was gob.g to be such that we would never locate it and that was exactly what our problem was .

Now the Woodleigh

s i te , I feel might have been a little bit different: We had such a good sighting cue in that Sharksmouth Bay, and there was no doubt in our mind where the target was the one time we saw it with t he smoke and in relation to Sharksmouth Bay, and eve:cything that if we had had some fuel up there, we ve:cy well may have seen those targets far enough out t o acquir e the s i te and start t r acking and then we might have gotten them some useful dat a .

No doubt in our mind that we’d

lu€0MFIDE~fFJAL

~F.IDENT!ts#-

241

have had a heck of a lot easier problem if the visual acuity targets had been located up in Yuma and not Laredo .

Everytime we came over the West Coast , if

I didn ’ t see Yuma, why I was surprised because I think!I acquired Yuma every time - - it ’ s real easy to pick it out of the desert and there was many clues to lead you right where those vis targets might have situated if they had been in the Yu.ma areas, and I felt that you would probably see them.

And I still think

this is a real worthwhile experiment .

I think it ’ s

good for 7, but it ’ s got to be revised considerably . They have got to move that Laredo l ocation , Cooper

Okay.

It was on the f i r st

Zodia,5e.l Light Photc—gra.:phy (s 1) Conrad

Why don’t you give them the word on that.

Cooper

Equipment set up and usage - - we didn ’ t have any problems in sett ing up the camera - - all set to go by the procedure that we developed for using the Southern Cross and pointing up towards Alpha and Beta Centaurus with the top part of the reticle worked out all right .

We don ’ t know yet what kind

of data we got , but we followed the pre-agreed method for where we put the reticle and for turning the camera on and how long it was held on there and then proceeded on around to Gruis , pointing up towards Fomalhaut and held on there and we didn’t thrust any during the film .

I think there was one

film sequence we had to - - we still were doing a little thrusting to get into attitude on one of the longer observations and we recorded this on the recorder and should be on there as to the times and everything. 11 . 7

Inflight Exerciser (M-3} ’ We used it extensively for both medical passes and

244

for regular exercise through the day—both of us used it.

There was no noticeable changes in physiological

condition.

I think if anything, it i~ easier to use

inflight than it is on the ground, und.er lg I mean. One thing I might recommend is that ii have some little better method of rolling up in maybe some kind of velcro strap fastened onto it to be able to roll the thing up into a stowage type configuration.

This is

one thing when you start to stow it anywhere , it tends to keep unrolling and getting all over the place.

But

i t worked very well—no problem. 11 . 8

Inflight Phonocardiogram (M-4) Cooper

As far as I know, it functioned all right.

It was

just like any other sensor, it itched and was trouble some as far as another sensor~

It was not comfort

It was extremely noisy.

It YOke both of us

up everytime it actuated — with a loud thud and hisses of air— and I don ’ t care what anybody says in a very quite room, it was very defi nitely objectionabl e and I won’t change my opinion of it one bit !

It was too loud and my recommendation

woul d be if they can ’ t decrease the noise of this valve, that it be eliminated from any flights . Your M- 1. Conrad

My M- 1, huh?

Yeah , that was a crazy one.

FCSD Rep

Let me ask one question on this.

You didn’t say here .

Did you feel anything? Conrad

Yeah , let’s go into that .

I very definitely felt

that after we finally spent many hours down her e with Gene Tuggs and rebuilt the cuffs — yeah , they were doing the job that they were designed to do. They were cutting off the venous flow and I could feel that in flight.

11.10

Cloud Top Spectrometer (S-7)

Cooper

Here again , there weren’t a:ny problems in the hard~1are in the flight that we didn ’ t know about before flight.

There were two

occasions where the spectrograph I s shu·;ter was re leased inadvertently e i ther in stowage or unstowing and the main shutter had not been — just as we knew- this is a very weak point of the mechru1ism because all you have to do is bump it against some·;hing and the spectrographic shutter was released — which ruined the whole — that particular exposure •·- you had to recock the whole thing.

As far as the procedur es

of using it, it was easy enough to use , it was a ld.ttle bit cumbersome in shape but we used it holding i t — the lenses upright up high so tha·; they got out t he window.

I think we got them some good data if .

Pete will get the log out here he can r ead over that . We recorded on the voice recorder as long as we had any tape .

We recorded comments on t he clouds, their

appearance , and all that while making ·;he photographs . Conrad

Now, all the photographs taken were specific photo graphs requested at a specific time .

‘.:here were

some that were requested at a specific t ime that we didn ’ t get.

I think the experiments pHople have those

247

down or they can correlate it real easy if I give you the ones that we got .

So we had a — and we

alwrors took two sets , one at an eighth and one a t

quaYter , so we had a set at 1 day 20 hours 2 minutes and 30 seconds, and we actually would up with four pictures .

Apparently they requested four.

Then

we had another one and that was cumulus clouds wherelver the location was — Gordo took the pictures I

and another one on the second day 21 hours 33 minutes and 02 seconds , four pictures of a tropical storm.

On the third day, 6 hours 32 minutes and 46 seconds we had four pictures taken over the Philippines of clouds in the Philippines .

Then the next frame ,

number 13, was exposed accidentally.

And then on

the third day at 21 hours 20 minutes and 8 seconds , it doesn ’ t say what the picture was made of — but~ set were made — of an 03 , mode 03 — that was , let me look and see here . Cooper

Right , I think that was

Conrad

S- 7, 03 Eastern Pacific and then we had on the fourth day at 3 hours 20 minutes and 25 seconds , we had a Philippines/Guam area set again, then on the third day, 20 minutes 35 seconds, you had one taken there t Gordo, whats that white something — oh , that white

248

calibration card—that was frame number 18, Conrad

Then on the fourth day 16 hours 37 minutes 00 seconds, you had thunderstorms over someplace---is that right- thunderstonns?

Cooper

Yes , the tip of_ Florida, up right off-•-

Conrad

Yes, thunderstorms off the tip of Florida—that’s right, they ask for that.

And then on the fourth

day, 19 hours 44 minutes 02 seconds, we had another Eastern Pacific for_two pictures.

Then on the fourth

day, 21 hours 09 minutes 25 seconds, t ropical storm ‘Doreen—two pictures.

Twenty-seven wHs tripped in

the spectrometer again—the twenty-seventh-Cooper

That’s right.

Conrad

Then on the seventh we had seventh day, 4 hours, 18 minutes 21 seconds, we had another Philippine/Guam area.

Cooper

Right

Conrad

Two pictures.

Cooper

Yes, and that was it for the cloud to1> spectrometer.

11,11 Miscellaneous

Cooper

Celestial and External Observations. Zodiacal light .

Conrad

Quite clearly—twice.

We saw the

249 Cooper

Clearly.

We saw the air glow as usual, always

around everywhere - - around the night . Conrad

We did see streaks in the air glow that they talked to us about — the dark streaks in it which ’ Jim and Ed mentioned.

Cooper

They are really definitely there .

Right — banded are~s .

And we saw this one in the

southern Aurora down on the southern celestial pole which was quite - - pretty unus~al.

Reall y hard to

def ine at f irst too — just what it was. Conrad

Yeah , it looked like a part of the air gl ow, but it was actually an Aurora - - i t changed the

Cooper

It changed the air gl ow thickness too

Conrad

Changed the air glow thickness and it changed the smooth curvature of the earth — it put a halt in the black outline of the earth —

Cooper

Right.

Conrad

And i t was a very green band of what you’d — what kind of Aurora do you call that where it is sort of like a sheet

Cooper

Yeah

the

stria or striden — somethi ng like

that . Conrad

Yeah.

Cooper

Then one other — the only other observation other than we did see a lot of micrometeorites and I saw

250

one large meteorite enter underneath U3 Conrad

Observed quite a few underneat h us—

Cooper

There was ver-✓ seldom a night went by that you couldn’t watch just for a few minutes to see a micrometeorite or two of them enter.

One meteorite

came from a l ong way out burning and went in under neath,

There were two other si gnificant things.

One was the observation of the moon. rising out of the airglow .

The moon was

We had about a quarter

moon and you couli seo the entire moon lit partially and then t he one part o:f i t lit brighter .

r eally appeared in t hree dimensional wlth the sun back over back off the horizon light:L-1 5 it . was quite spectacular, I thought . l ooked very unusual.

This

I bought .i.t

The other observa.ti0ns in t :‘le

vicinity of the Magellanic Clouds, and actually in t he vicinity where this Gegenschein Li1sht is- -i t appeared to me to be two to three a:~~eas that looked like Magellanic Clouds, only mu~~h smaller. .·, !

There were two or three other little Magellanic Cloud-appearing thi!lgs, anything.

‘l’hey weren’t elusters or

I think you noticed them several times

too over there when we we~~e fiddling around the Magellanic..Clouds, I never could decid•~~ what they

251

Conrad

Yes, we kept looking over the area of Gegenschein to see if we could see and I don’t really think it was the Gegenschein, but—

Cooper

There was one area right almost in the immediate area of the Gegenschein, but not quite .

It was

very near that area by maybe five degrees or so though.

There was this one area which appeared

like the Magellanic Clouds . Conrad

Like a real small one .

Cooper

Yes, it looked like a small Magellanic Cloud. That’s really what it looked like.

I t was quite

near the area where we had been told the Gegenschein should appear; but, then there were a couple of others of these that similar types back over closer toward the other of the regular Magellanic Clouds .

So ,

I don’t know what they were , and I didn’t notice these before on my previous flight. something that were new to me. planets.

These were

We saw a l ot of

We did try taking the polaroid, the two

sheet polaroid filters , and rotating them to all different positions to see if we had circular or linear polarity coming out of the sun.

tried the sun both while well up and while setting.

~~19E►~~:JtA b,

252

Everytime while setting, it seemed to have linear polarity, somewhat vertical , but I never could pin this down to anything well- defined.

While the

sun was up, well into the sky, I could rotate the filters and rotate them within themselves to any degree and couldn’t discern anything but equal polarity coming out of them in all directions. It didn’t seem to have any linearity to it at all or any well-defined specific axis of linearity.

never could see anything from the sun other than with the polaroid filter in .

After the sun had set,

you could see quite a glow with the polaroid filter in, but at the same time you could see it without the polaroid, too .

A couple of times when we got the

Zodiacal light quite strongly—

FCSD Rep

Can you see the stars down through this airglow?

Cooper

Oh yes.

You can see the stars right on down through

the airglow.

The Gemini window is much cleaner

in general , apparently, or much better visibility out of it and night visibility than the Mercury window, because we were seeing down to about seventh magnitude of stars .

We saw the clusters

in Orion and we could see seven stars in the belt of Orion.

We saw a great many stars which we couldn ’ t

”’-=eOMFlf>El’4TIM.

begin to see in the Mercury flights .

In f act , on

the basis of the number of stars we’ve seen, our recommendations are that you crank up the planetar ium at Moorehead and increase

the brightness of

it over the l evel at which we were studying it be cause it was, to me, rather confusing when we got up there due to the number of stars we actually were seeing.

Didn’t you think we needed to up the

number of that you actually see? Conrad

Yes, very definitely.

You see quite a bit of the

sky. FCSD Rep

Did you get any pictures of opportunity of something —something that you really remember— that wasn’t scheduled?

Conrad

Pictur es .

You mean photographs?

FCSD Rep

Yes .

Conrad

Oh, I think we have some outstanding photographs in there if they came out .

FCSD Rep

I mean something that m~be you wanted to take a picture of that wasn’t on the—

Cooper

Oh , yes .

.le took a number of pictures because—

Conrad

We got some real good pictures coming across the states , with the clear day we never expected to see, where we got two or three of the big major cities

254

in the middle of the States , like Dal l a s , For t Worth , and J acksonville . Cooper

I tried some nighttime photographs with the 200 mm l ens on high speed film with s ever al different speed setti ngs just to see i f they would come out and what they would come out like- -

FCSD Rep

Of what?

Cooper

Oh, of Orion and s everal of the constella tions- several celesti a l fixes—once of some airglow , I t ook a picture of that aurora tha t we saw over there and , of cour se, all kinds of su~set s , sun rises , and the moon coming up through the airglow, and things of this type .

A l ot of di:n light stuff

we took with hi gh speed fil m. come out , I don I t know . of the exposures .

It may or may not

We were gues,3ing a t some

A gr ea t many thi ng:3 on the ground,

of course, we took pictures of tha t w1~re unexpec t ed things tha t we just thought were real t arge t s of oppor tunity . FCSD Rep

Okay , that’ s the end of the experimen·~s .

255 12.0 PREMISSION PLANNING 12 . 1 Mi ssion Plan (trajectory ) Cooper

On these l onger flights you have to be prepared for more real - time mission pl anning, which we were . And we had planned on this perhaps being the case and we hel d al l the flexibility that we could in our pl anning.

You need to get a ll of the key things

that you ’ re going to do planned and trained for as well as possible, but the way you fit them together has to be flexible .

This applies more to the flight

pl an than it does to the over- a ll mission plan. 12 . 2 Flight Plan Cooper

Flight plan almost invariably winds up being l argely real-time planning.

12.3 Spacecraft Changes Cooper

Spacecraft changes has al ways been a sore point with me and stil l is .

I can ’ t emphasize enough to give

the crew and everybody el se a fair shake by hol ding spacecraft changes to a real firm, hard freeze date. No more changes should be made after a certain date because it adds hardship to everybody invol ved, and does not allow the crew time to train.

Some changes

are going to be necessary because of what you find out on the preceding flight, but I think they should Jl

~ WFIDel>~TIAL

256

be held to an absolute minimum. 12.4 Mission Rules Cooper

I think that the mission rules were i n general very heal thy .

I think the attitude of the FOD toward

mission rules was very good.

It was obvious that

just as we have seen many times before, that FOD uses the mission rul es as guidelines and certainly wil l deviate from them to keep the f l ight going, but keep everything as safe and as smooth as possible. I real ly can ’ t quibble with the mission rules we wound up with at all . Conrad

I think they were very good.

The mission rules on the fuel cells were the best things we ever had, they were written real opera tionall y.

I would l ike to compliment the people

who wrote those rules . 12.5 Experiments Cooper

Experimen ts is a sore point with me b<?cause I again feel like the flight crew get trompled on all the way down the l ine.

There is no polic;r that has ever

been held to or ever backed up on adhBring to an experiments cut-off date.

Very obviously, there

were a couple of experiments thrown in on a politi cal basis and nothing else .

I feel that this is not

fair to the experimenters and to the flight crew, I

257 nor is i t fair to the operations people when ex periments get cranked in past the experiments freeze dates .

I feel that these freeze dates shoul d be

estab l ished early, agreed to by everybody concerned, and shoul d be hel d very rigidl y to .

Unl ess a safety

of flight or a significant development occurs warranting a spacecraft change, the f r eeze date shoul d be adhered to .

If you don ’ t , ,you affect

hardware, you affect al l the previous and subsequent training a..~d planning involved , and you compromise everything as well as the experiments which did meet the agreed- to schedul e . 12 . 6 Training Activities Cooper

We were extremely short on time to do adequate flight plan training.

Although we had it pretty

well in hand, but it was still very marginal .

guess it was just as well since circumstances re quired considerable real- time pl anning.

It woul dn’t

do much good to get timing patterns down real pat on these things anyway.

Us ually it boil s down to

doing them real time.

There were s everal experiments

that I would have liked to have had a l ittle more time to run practice on the simul ator, or, at l east sit down and lay out exactl y how we were going to

258

do it .

Although experiments worked ,) ut r e l a tively

we11 , we could have used a 1i ttle mo:c:-e time on them. Conrad

Concerning mission planning.

I would avoid wiring ,:.

experiments such as MSC-1 .

They clo·:iber up very

critical time phasing in the mission.

For instance,

arming the Bus Arm Switch at SECO added an unneces sary step at an extremely time-cri ti,::al time, which is just pure lousy engineering pl anning.

That door

cou ld have been blown by any number ,)f circuits. It didn’t have to put i t on that one. Conrad

The next thing is the laying out of t he flight plan . It became obvious that we were crowd,3d ,

So , I think

they should take a more objective l ook at these quential aspects of f light planning, particularly in terms of how long it takes t o complete one ex periment.

This business of being pitched a ll the

way to the nadir, going backward, th,m having to pitch forward again to pick up t he next target , is time consuming.

Neither the flight plan peop l e,

the crew, nor anybody el se for that rnatter picked this up until we were flying . Conrad

There was a tremendous mistake made in the pl anning on our f l ight.

We assumed that everything was going

We ran into one computer anomaly where the com

puter kept running and running and I still don’t lmow what that was. Cooper

Had that occured during the REP exercise we would have really been up the creek.

Conrad

That’s right.

In pre- mission planning we should lmow

what the most critical systems are to be checked. For us there was the Platform, Computer and Scanners . One of them bit us and that was the Primary Scanner.

GO/NO GO ’ s—I think we ’ re fine .

I don ’ t s ee anything

wrong with the GO/NO GO’s. 13. 2

Pl~ and CLA Updat~s Cooper

I thought those went all right .

Do you?

Conrad

Yes , we had a hip pocket place to go on every or bit .

Consumables Cooper

Consumables—In general we had a pretty good handle on those.

:.,onrad

The oxygen, the OAMS- -

We had one anomally on the OAMS .

I still don ’ t think

we lifted off with the right OAMS propellant . Cooper

No , I don ’ t think so either .

We had 87 percent- -

Conrad

87 percent on liftof f and they never answered that question for us .

Cooper

We did ask why we had this r eading rather than 100 percent and we never got that answer .

We asked this

shortly before liftoff . Conrad

This may have had to do with the fact that we had full fuel but not a full load of oxydizer based on that 1 , 25 mixture ratio.

My understanding was that

we were supposed to liftoff with 100 percent on the gage.

I ’ m not saying that wa s correct but it took I

us by surprise when they blew the Squibs a couple of minutes before liftoff and had 87 percent

«e~~FIDi~~il.l;<L

on the gage. Cooper

Electrical—1 don’t think there was a:ny problem on the electrical system.

The problem Wc,s in the

cryogenics rather than the electrical.

I should say

in the cryogenics and in the water product of the fuel cells.

These were the limiting things rather

than the electrical power we were using.

As long

as you could run the fuel cells there was no limit to the power you could pull off of them. Conrad

Let I s put that to bed right now.

The GPO fluffed

powering up those fuel cells after thny ’ d been powered down .

If our electrical prob:.ems didn’t do

anything else, we got to cycle electr:_cal loads all the way through the flight on those fuel cells . As far as I’m concerned , those fuel CBlls are flight proven.

Every fuel cell in every spa<!ecraft that

goes off should carry the maximum loacl of RSS supply so that he has all the electrieal power that he wants to use.

He can run that pla·;form, computer ,

or any combination of electrical gear that he wants anytime during the flight. experiments.

kept pinching electrical power and pinching electrical power.

I think we proved that the fu<~l cells can take

,.,,

the load .

It shouldn I t be any problem to

fix a couple of things like that .

There ’ s no

doubt about it, those fuel cells can go up and down, and up and down under load and they will ha.ck the course.

We sure gave them a beating. Especially

that Number 2 fuel cell . Cooper

Can ’ t say enough about the fuel cells . they did real well.

I just think

I was extremely impressed at the

end when we kept loading them down .

We loaded them

down even more and the doggone thing began to come up rather than fail, go down or poop completely out . Conrad

That thing stayed on sixty o~ seventy hours of the whole flight .

That ’ s a lot .

It must have been

sixty hours at least . Cooper

I think that the fuel cell really goes into a hybernation period when you cool it down . it almost hibernates like a

Conrad

storage battery.

The way to bring it back to life is to load it down to get it warmed up , and then to purge it .

•

I think

And I

would have liked to super purge that Number 2 cell a couple of times to see if I couldn’t have brought it up higher. Cooper

Yes , I think it probably would have wor ked.

The

Conrad

We didn’t always agree with Mission Control.

One

example—! would have l oved to argue with them about the heater circuit on the OAMS.

I was against

turning it off . Cooper

On fuel cell—do you want to go back tc OAMS.

We ’ ve

already gone by it. Conr ad

Yes , I ’ m a curious person by nature and so is every body else that flies one of these spacecraft.

When

you s end up something you ought to tell them why you ‘re doing it .

Especially when we get into these

screwy conditions .

We didn ’ t have any choice when

t hey said shut down the fuel cell but to shut down t he fuel cel l.

It wouldn’t have cost them another

t wo words to s ay what they were trying t o do.

I think

i t was obvious to us what they were trying to do . I tell you , they made some decisions down there on t he ground t hat I ‘ll still sit back here and argue wi th them about . Cooper

Yes , you are right on that OAMS heater .

Conr ad

OAMS heater was one of them and another one is the manner in which they conducted that solenoid warmup idea on the OAMS system to unfreeze i t . poor way of doing it.

That was a

EeJNFIOEr-qTIA t Cooper

That was a very poor plan.

Conrad

That wasn ‘t thought out very well.

265

I think, in that

particular case, we had all the time in the world to discuss that with the ground .

We could have

gone a couple of revs talking that one over and it wouldn ’ t have made a hill of beans . Cooper

I think the time that they chose to do it was ill planned .

Every test that they laid on us wound up

to being a test in the middle of the night . know why.

I don ’ t

I ’ m sure this wasn’t planned that way,

but that is the way it turned out.

Anything else on

the fuel cells , batteries, or mission control? Conrad

No .

13 . 4 F’light Plan Changes Cooper

Flight plan changes—I think here is one thing that we want to say about mission control.

I ’ m well

aware that the flight plan people were kept extremely busy having to do this tremendous amount of real time flight planning.

I think in general Flight

Planning back there did a fine job .

I’m sure there

were a lot of the people coming in and adding this and that and changing this and changing that. There wasn’t enough thought given to the crew.

The

crew was extreme~ co,.u.romised throughout the whole

€0NFl91!1’~ 1-1Ai.

266

flight in the way the flight plan changes were made . This was unintentional, I’m sure . Conrad

We had to blow the whistle on it.

Cooper

They did things like trying to keep one man busy a l l the time , just to keep him busy.

It was obvious

that was exactly what was being planned .

Certain

experiments were put on one man when th,~ other man was asleep then the other man whe he wa:, asleep without any thought being given to who had what or which side of the cockpit. Conrad

I think , that we documented this \vell enough, and I don ’ t think the 4 crew emphasized it enough; but, the people on the ground don’t realize how long it t akes to perform these other mundane taf,ks that aren’t scheduled such as :

hygiene , food., etc .

They did a llow long time periods for focd, but there were other things that they didn’t allo~ the time

Cooper

for such as :

garbage , cleaning, etc .

That’s r ight .

General housekeeping and cleaning

up the spacecraft . Conrad

I think we can straighten this out with them.

Cooper

I do to , but we are talking here about flight plan changes in mission controlling. as critical as it sounds .

I don’t mean this

I want to say I think

‘l@ Ot~~FIDE ►~~TIAl they did a fine job .

I think they made a good effort

to salvage a ll we could ou of a poor situation . .

”

I think they really did a fine job .

As a resul t

of what we found , and we didn’t know before we got into the real time situation; we discovered that the people compromised are the flight crew.

They

wound up cutting into sleep periods and certain functions were performed at the wrong time for each one of us.

It could have been better planned as

for as who did what when.

13 . 5 Systems Cooper

Mission Control for syst ems .

I think the biggest

handle you have on systems is right on board , and I still think so .

I think we had a good handle on

what was going on.

The things that presented a

real question were the rate of decay , the rate of dwindling, some of these cyros , etc .

The ground

got a good handle on them and began to give us some good informat ion on what we could expect.

Although ,

I think some of them were new enough that the ground wasn’t aware of what was going to happen .

For

example, they didn’t know when they would vent and when they wouldn’t , what the rate would be when they vented , etc .

13 . 6 Experiment Real Time Updates Cooper

I think these worked out pretty well .

We mentioned

about needing a platform before and abcut needing attitude control .

And our OAMS system got worse

and worse where we had no attitude cont rol t o speak and weren’t allowed to use any, I think, a great many of these things that were put in ~ust hoping we might drift through.

They were sort of wasted .

It was a waste of time .

They could ha.v-e saved

our time , theirs , the writing time , and. everything involved, because trying to get some of these experi ments while in drifting flight i~ completely imp.o ssible. Conrad

It was really funny.

It couldn’ t have been better

planned to work out opposite.

They’d say get a

D-4/ D- 7, like the Milky Way—You ’ d expect to drift through the Milky Way long enougr. to get it . Anytime we had the gear fired up we nev-er got anywhere near the Milky Way. Co oper

No , we would always be pointing at the ground .

Conrad

There was one time when I tried to do it . pointed at the Milky Wa;y.

We were

By the time I found out

that we were going to drift through it and the t en minute warm up time for the gear passed, we were

269

I’d leave the darn IR gear running

for a while and we would never get near anyt hing

…

we could look at . Cooper

We never did get that end of the sun picture and yet the sun wa s in our eyes every time you would turn around.

When t hey would give us some of these

locations to photograph and gave us pointing informa tion, it was good.

When we had a platform

to use , I think , their pointing information was extremely accurate .

I was well pleased with it .

I thought it wa s right on t he money,

We never had

a plat form to work from so we couldn’ t evaluate the air-to-air,

The air-to- ground was quite good.

And you need this .

14, 0 TRAINING 14 .1 Gemini Simula tor Procedures Cooper

The procedures that we went through in-·it- and our t raining was pretty accurate.

I think that we used

the right procedures in the development of our checklist .

In going through the procedures we

should have ""tad; our fl ight type checkli~;t at an earlier date in order to get a little bii. more famil i ar with them and to iron them out a little more in the GMS.

We should have had them j or 4 weeks earlier.

System knowledge—I didn’ t feel we were t oo bad off system knowledge wise , did you? Conrad

No .

Cooper

We were pretty well on top of everything,

We had

a great deal of confidence in knowing the systems . The systems training that we got in the GMS on the fai l ure analysis a long with the lectures we got by t he systems people , both the GMS people and the McDonnell people , put us in pretty good s·1ape sys t em wise.

We were in excellent shape ,:::oncerning

launch t raining.

I might say tha t i f the::-e is any

changing to be done we should emphasize the nominal launch more.

We ran through al l types of emergencies .

We had some good sessions on the DCPS .

We had some

wasted time down here trying to crank up some of these launch failures that take quite a while to reset on the GMS .

We should have gone through them

on the DCPS and let them go at that.

was a

waste of valuable time during the last few days. Many precious hours were wasted cranking the program into the GMS to go through some of the failure modes that we could have done in a tenth of the time on the DCPS .

Due to the shortage of time we cut way

back on nominal training.

We could have had more

nominal launches, nominal insertions , nomina l insertion checklist, nominal preretro , and nominal re t ro, e tc . Conrad

The best day we had was the day before the act ual fl ight .

The day after we had scrubbed .

about 8 nominal launches .

We ran

About 4 reentries all

the way through to the end and that really put the fros ting on the cake. Cooper

Yes , we should have had another day of t hat before the first attempted launch.

As it turned out we

got into reasonable shape because of that one scrub date . Conrad

We really put it to good use.

We got a chance to go over the books some more and

272

learn things that really helped . Cooper

We were short on nominal time .

Conrad

I can ’ t say enough for the way Deke schEiduled the things when he asked for t wo weeks . on the button.

He was right

We could have used a couple more

days. Cooper

Yes.

Conrad

A little more nomi nal training like that to polish it off.

If we had, I don’t think Gordo woul d have

put the drogue out at 70 .

And I don ’ t t hink I would

have left all the Squibb batter ies off.

We shouldn’ t

make those kind of mistakes . Cooper

We would have had more time to run through the nominal procedures and get them down.

Con.rad

We ’ re the first ones to admit that we maie them, because we just di dn’t have the f light checklist . I finished all the time . We didn’t run· ~hat thing that many times .

Cooper

We ran very little orbita l training othe:r than the REP .

I think we spent a great deal of t’ime on the

rendezvous and the REP, because it was the first priority. Conrad

One thing that slipped by us , too, was that it took

COt-c!FIDEt◄TIM.

273

us a whole day and a half in flight to realized that these experiments were going to run so successively close t o one another.

The one thing

that we were not prepared for on the ground and had to learn in the air was how to organize a series of di fferent experiments to run them in a row. I ’ m not sure we coul d have figured this out on the ground . Cooper

One thing we could have done if we had had the time , we could have taken one of these Stateside passes that we knew would really be cluttered and run through it in real time .

Conrad

I think the recommendation here is what should be done in the future for a flight that had experiments like this one . sim-net- sim with Houston.

I ’ d run a

We had individually

er ected and taken down and put up every experiment enough times that we had no problem in assembling anything.

We had no problem in knowing where

everything was, we knew where everything was in the spacecraft and we got it in the shortest amount of time as possible even in the f light . have any

trouble in that way.

We didn ’ t

The one thing that

we did miss was, and they have a sim net sim of

‘90NFtoENll,_, ”

274

eoMEIDEt◄ TIA • revs 15 and 16 .

It might have been a good idea

if we ha.d listened to it in that we might have picked up the fact that the sequential ,::-unning required just a little bit different opnration. Again, I’m not sure that you can practice this on the ground, because at the times we ha.d the gear out we wouldn’t have been able to load any spacecraft on the ground the way we wound up using it in zero g. I had lenses floating on the floor and film magazines hanging by just a couple of little velcJ:o t hreads on the overhead which you couldn’t have done in a 1 g horizontal environment.

You couldn’t stow your

gear around the cockpit like you can during zero g. Maybe you might compromise here.

You mj_ght consider

a sim net sim to get some idea of how things are going to run into one another , and then if you ‘re up for 4 days or something like that, yc,u might take an orbit to lay out a series so y01:.. can learn how to stick stuff around the spacecraft. .

It ‘s

not apparent to you on the ground exactJy how you wind up storing that stuff.

We really ca.me up with

some new places to stash gear as the re~ult of being in zero g .

275

Cooper

Yes, that’s right.

Okay, rendezvous is not applicable .

If there was one area that we were pretty well trained on, t hat was retrofi re . Conrad

Yes.

Cooper

I think we were in good shape for retrofire .

We had

our checklist for a long time for pre-ret rofire and retrofire .

We were in good shape , well-trained,

and we went right through it like clockwork.

think this area we were sitting r i ght on top ot

problem at all . Conrad

We were in good shape in SECO, too . those SECO procedures in dandy shape.

We went through Got the

numbers out of t he computer and had all of the se~uences and so forth and got that well down in the GMS . FCSD REP

On rendezvous, how do you feel abou t the GMS training?

Cooper

The procedures that we learned in the simulator were fine, but you just can’t take away that out-the window simulation.

When you add the out- the-window

element to it , it’s di fferent.

It ’ s easier when

you kick the REP out a.hd there it is out t here visually you can do it fine.

The training that

we had up at McDonnell on that simulat or was just identical to flight.

Didn’t you feel like we were

\cOMilOEMlt~

276

• almost in the McDonnell simulator when we got the REP out?

Just exactly.

That training that we

did up there with the visual presentation was invaluable . Conrad

A lot of people don’t realize how time critical that whole REP maneuver was.

We didn’t realize it

even when we ran it a t McDonnell.

When we ran at

McDonnell , we had a visual di splay and no outside encumberances and no other systems. computer.

We had a

Gordo had a ball and an out-the-window

di splay, a reticle and a hand controlle:c-.

I had

a computer and an MDIU over there and t ·:iat was it. And we would s it there, shoot the breez,= , talk to the guys out the window and run that tb:i.ng.

don ’ t think we became aware of how crit :i.cal it was until we came down to the Cape and got :m that first sim-net -sim . on the horn.

Then we had the ground honking

They wanted information.

We had a

spacecraft around us in the GMS , and theiy could throw in little cliches every once in a while, which t hey did .

It turned out tha t we e~t little

cliches in flight starting out.

The one• thing that

we spent an awful lot of hours on was the REP.

277

I’ll tell you I wouldn ’ t have given you a nickels chance if we didn ’ t have up systems.

We would have

had to fallen back on one of those backup jobber doos .

That would have been pure luck.

wouldn’t have made a mistake reading it.

Eut I You

are

just reading the checklist.

They were extremely

complicated and long-winded.

Now I guess they

simplified this a lot in Spacecraft 6; we were up against the wall.

We had to stop somewhere ; take it

and work with it or we weren’t going to get it done .

They were still in the process or ironing

out the procedures.

We did more of an eva luation,

although it was a learning process, but we were involved in the evaluati on stage , which was not the time for us to be doing this.

278

Conrad

Let me just add one thing.

My recommendation is

tha t you are going to have to be extremely careful with the mission planning people becau:rn I saw what happened to us .

Every f l ight is going to have a

different rendezvous.

Somebody is going to want

to start changing s omething, or mickey•-mousing around.

I think it is going to wind u:;, to be a crew

responsibility and that a couple of mo,~ths before the f light they really put the axe to them to stop. vlhether it is the best way to do it or not , the more you do in rendezvous, the more complicated it is and the more time critical it is doing the maneuvers . The computer is a complex little gadget and can really f oul you up if you make one mistake.

‘3o , training

wise I can 1 t emphasize running the mis3ion the way it is really going to run in real time.

We haven’t

enough time to really get it down. Cooper

Cut i t off at an early date , s o you ca1 adequately t rain on i t .

I can’t conceive that you could ever

get the off-sets that we were using in some of our r etrofire training.

Plus , I don ’ t th~1k we are using

the right torquing moments on our Rate Command system.

The trainer doesn 1 t have anyw.~ere near the

brute power that the actual RCS Rate CJmmand has .

279

It is a great deal of difference. Conrad

Yes , it was a pretty tight system.

This is probably

a function of each individual syst em because I remember Jim mentioning the fact that it was so much sloppier in Rate Command RCS and there is a differ ence in the tolerance. to us .

But it sure wasn’t apparent

Both the OAMS and RCS Rate Command systems

were just as tight as they could be. Cooper

Well, the OAMS Rate Command system definitely was tighter because you could come zapping around with it and the second you let go of the handle it stopped right there .

Barn, it never even quivered , just

held right there . Conrad

Yes, we must have had an outstanding set of rate gyros.

The RCS Rate Command there had a wider

band.

There was so much power and authority

in the RCS Rate Command that it actually gave me a little bit of problem just hitting the point, getting lined up on it for retrofire .

There was just

so much authority you had trouble getting just small amounts of control force until you got used to it.

There was so much power there ,

almost more power than you needed for fine contr ol .

It would be interesting to simulate

280

similar contr ol torques on the GMS to Eee what kind of off - sets it would take before contr ol problems are encountered.

I don ’ t belj eve that

you would actually set one of the rockeits off enough to bother you.

Possibly, you could

since it is not a straightline functi on. Cooper

We had had adequate amount of reentry ·;raining. If we ’ d had a thousand hours more we would not have done anything differently than we did.

Conrad

The reent ry in the simul a tor and the roentry • in flight up to a point went right down the line , I would say to slightly after guidance initiate .

Then, the ball angles were ~xtremely

steep in flight in comparison to the h·ainer.

would very much like to go back and ta«e a look at this on the t rainer while it is fresh in my mind. I always use the horizon for roll reference in addi tion to the r oll bug.

The horizon di sappeared too

soon on our reentry.

We were looking at all white

on the ball there for a long t ime. Cooper

We pitched on up pretty good.

Conrad

Yes, we trimmed out at an awful high angle.

The

stagnation point on the spacecraft inc.icated we were

281

in the ball park with the previous spacecraft. Cooper

It had to be traveling right because as long as you keep your rates zeroed it is going to trim to its proper trim point.

I agree with you completely.

seemed to me as though we trimmed a lot nose higher much earlier in the reentry than we did in the simulator.

You have less nose up above the horizon

for a longer period of time in the simulator than you do in the actual case. Conrad

That was the only thing that seemed different about the reentry.

Cooper

It didn’t concern me because I knew we were damped and trimed out okay.

Conrad

Yes , I knew we were in good shape , but it was a sig nificant enough difference so as to be a glaring dif ference with the s i mulator.

Cooper

I don’t know whether it actually was the case or not , but the reentry seemed to go much faster than it did on the simulator.

Conrad

From Guidance Initiate to 100 000 feet , it seemed to pass at considerable less a.mount of time than it does in the simulator .

Cooper

Yes , it sure seemed to me like it did .

That is some

thing I think we ought to have people check into to

282

see what the actual time difference ws.s.

Maybe it

was just us. Conrad

They can ring that out real easy.

We can improve

the reentry on the simulator a little bit, it’s different in this respect. Cooper

Okay, Crew Station.

I have the same C)mment that I

made after Mercury on that .

I think t::lat it is just

t oo bad that we can ’ t have horizontal 3imulators be cause that is exactly the way you are :in orbit.

You

are not laying on your back, you are ~1 a horizontal configuration.

If your simulator ran horizontal you

would be standing just like you would be in orbit. Orientation is entirely different. Conrad

I compliment the Gemini crew station on the layout of t he para.meters that are displayed to you.

I feel that

there are some other para.meters that I would like to h ave seen displayed in the spacecraft throughout the fl ight .

As an example, I ha te to rely on the ground

for radiator temperatures or have them call me to heat up a cooling loop. onboard function.

That type of thing is an

It is very nice that the ground

monitors and takes care of you.

The spacecraft was

extremely well layed out , and as we thought in the simulator it turned out to be true in flight .

€0►◄ Ftf!JEMT Cooper

283

I think the simulator people down here did a great job getting the simulator up to our spacecraft configuration.

Conrad

Yes .

Cooper

When we came down here it was pretty close to oux flight configuration.

Conrad

Yes.

Cooper

Stowage wise, they had i t in pretty good shape.

Conrad

With particular reference with Apoll o , having worked for 2 years in the Apollo cockpits , and having now flown a Gemini, and knowing that these t wo cockpi t s have been layed out as f ar as I’m concerned, with two different philo sophies , and I think this i& the right one.

I can’t really say how accurat e t hey uere because we had a nominal mission. good training.

very good, very essential .

I think there again we

have to be very careful not to over emphasize it. I don ’ t believe we did in our case .

J think we had

just about the right amount , although I think there was a number of people who were concerned that we could have used maybe more DCPS . Conrad

I’ll say one thing about the DCPS hor izon.

thought that that worked out just almost the way it actually happened. (’

Cooper

Yes sir, I do to.

the same t i me you saw - Cooper

I think that DCPS should really be utilized to ad vantage as far as this out-the- ‘window reference .

Just

crank it just a l ittle beyond and do a little bit of work as far as out- the-window referencing and I think it wi ll be an extreme help . Conrad

14 . 3 MAC Engineering Simulator Cooper

Okay.

The MAC Engineering Simulator .

Conrad

I can’t say enough for that half a day we spent on launches reading out Math Flow 6, on the computer.

Cooper

That’s right.

And the reentries . .. •

Conrad

That•s the most worthwhile half a day I spent as far as my side of the spacecraft went .

Cooper

The reentries I thought we did at MAC Engineering Simulator were just exactly’ like the reentry we did . I think it was real good .

I think, of course, the

rendezvous we did up there .we tave al ready mentioned, I thought were probably one of the best things we did .

14.4 Centrifuge Conrad

We didn ’ t miss the centrifuge at al l.

The fact that

we didn’t go , I didn ’ t feel that I wae1 left out of anything. Cooper

No, I don’t think we missed a thing wi th the centri fuge.

Conrad

I think you should ride it, you know, a time or two or something like that.

Cooper

I think if nobody has ever ridden cen·;rifuge—

Conrad

• . ..boost profile or reentry profile :.s worth running a coupl e of nominals in your shirt s l eeves.

I don’t

think you need instruments or anything, but-Cooper

I think if no one has ever ridden one before I think it is worthwhile they ride the centri::uge just to get the fee l of what it is like. never even feel those g’s . got g’s.

But, so far as— you You don’t even know you’.ve

You are so busy doing thing13 and you ‘re

just “clickt y-cli ckty-cl ick.” at all .

You don ‘t notice them

And that l evel of g is not en ough to even

worry about.

5 Translation and Docking Trainer Conrad

The tracking tests that we did on the Agena, you know, for the camera, was real good.

I diQ1 1 t do the one

up in Denver but the one in the Agena was real good, up to, and of course we woul d onl y get up as far as

@@++FtDE~+.11”:

287

the nadir, but I think it wa.s helpful and I think f l ight proved the same thing that we concluded in this , that it wa.s a. very simpl e task , once you ha.d acquired something… … the track. Cooper

Once you ha.d acquired something, yes .

Conrad

The one thing that I, to this day gave me the funniest sensations though , is when you track through the nadir and the things started to speed up and reverse I get the weirdest sensation that we passed the nadir and got a.bout 30° going behind us .

I almost had myself

reversed in flight, like I wa.s coming up on it again . Now , I can ’ t explain the feeling but it was weird. Cooper

It’s a real odd optical i llusion where you a.re like you are in an inverted spin-type situation.

You a.re

looking—going back over here and the angle out is changing such that you al most do have the feeling that it’s - that you have suddenly s tarted changing your whole angle … . Conrad

And if you’re looking a.t the nadir , and you’re track ing through in just one axis , pitch or something like that, invariably you’re off a. l ittl e bit in yaw, you see, and you’ ll get going, all of a sudden it will start speeding up , and if there is any roll in there a.t a.11; all of a sudden the roll will pick up ,

288

• so all of a sudden this target which has been going this _way and getiing a little bit smaller al l of a sudden the whole world will start t o roll on you too as you are gcing away.

had the feel ing that I was falling over a cliff every time we got back to the end of that thing. Cooper

It was pretty weird.

14.6 Planetarium Cooper

Well, here again, I just can’t emphasize enough I t hink that a lot of people under play the val ue of the planetarium.

I think Pete even agrees with me

now that boy, that doggone planetariUIIJ is pretty e ssential training , Conrad

Yes , i t felt … . pretty good.

Cooper

The planetarium, unfortunately, is an item in your t raining program that is very easy to cut out.

You

say well I don’t really know that, I can take along a star chart and I can recognize these, and we all t end t o do that.

We all tend to try and fall into

t hat. Conrad

I tell you, we would never have gotten Nye 1 s Zodiacal light done without having gone up there at the .. . and taken his displ ay on it.

Cooper

Oh, yes.

If we hadn’t gone up there a ~d actually

gone through it we would never had don= it.

‘CONFt&li►44~ /ttl

289

Conrad

And with the gun site superimposed, excuse me, reticle superimposed on it.

Put it right there to

orient it with the Southern Cross and Grus and Fomalhaut we would have never gotten that experiment done , without having gone through that really that half a day did it for that experiment. Cooper

Yes .

That salvaged the experiment .

Of course he

will probably ruin the film anyway ,

The celestial

identification up there t I think one thing that I recommend that we are going to have to crank up the brightness of the stars because we have had them cranked down to the Mercury level here all this time and it’s just too confusing when you get up there you see so many more stars than you did in Mercury ,

so we are going to have to raise the level, brightness level of it back up.

Up for the training that we

do because there were multitudes more stars than we had been trainL~g on. Conrad

The stars move around in orbit too fast to use them for spacecraft orientation, as far as I was concerned. In other words I might recognize a constellation out there,

The Southern Cross or Orion or something

like tha t , but unless you know your exact point of time and have a star chart sitting m front of you

290

and even with a star chart sitting in front of you it wouldn’t help you with spacecraft orientation. I take it tha t what you are saying.

Do I know

what I am in roll, pitch and yaw to the horizon, or something like that.

I don’t think so, because

most of that stuff is moving too fast up there. Cooper

Well , so far as it’s yaw orientation :.t gives you relatively good angle.

For instance you always

know if you swing around just one lit·;le

You

remember when we would swing around and there was Cassiopeia, you knew that you were hended generally north. Conrad

Well , yes that ‘s true.

You knew that you were on

one side of the tra ck or the other. n

Cooper

Pleides and the … whenever you would see the Pleides, it always points east, so thnt gives you a clue and there are several pretty good clues and I always lmow when I see Delphinus that the Summer Triangle is near by.

Conrad

You’re right, it would tell me where H was pointed but it wouldn’t have told me anything in roll.

othe.r words I wouldn I t say that I would use it completely for a three axis spacecraft orientation . It might give me an idea of which way the sky was

-IM

291

pointing but that wouldn’t tell me whether I was upside down or right side up or anything , but I don’t know the stars that well. Cooper

With the accurate star chart updated and then finding the stars on there , then you could use them for spacecraft orientation.

Conrad

I’m taking this to mean you are talking about a quick orientation, you know, I aborted in the middle of the night on launch if I went on a night launch, would I know which way I was going? I don’t think so .

Cooper

I don’t know.

You would be very lucky, you would just have to see one you could recognize .

Conrad

You can take your time when you are planning in advance.

Okay.

Now you want to use Orion to

line up in a certain way with my reticle.

Now

that’s a different story, but that would have to be done at a specific time because Orion moves all the way through the sky and it turns over on a 72 degree launch azimuth. Cooper

Well , tracking task.

We didn ’ t cover that but I

think it is pr etty obvious that you can use it for tracking task we found .

•

@OfictFtDEf~TIAP •

292

Conrad

Oh yes .

Cooper

Spacecraft orientation. help on that .

I agree, you need a little

It would be a help ~o find a horizon,

but you could get pitch and yaw on it md then maybe use the stars as a yaw orientat i on.

14,7

Syst ems Briefing Conrad

Well , boy I can ‘t say enough for the t;rpe we got at McDonnell - were relatively different in nature and the type we got down here but I can’ t :,ay enough for both of them because they are both essential.

I’ll

t ell you old Bob Snyder’s one remark about that cryo stuff being abl e to go through that heat exchanger as a liq_uid and not bother anything would …

just can ’ t say enough for how that took the load off of our minds when we were up there . Cooper

Yes, I think the —

Conrad

A lot of little tidbi ts that we had out of these, specifically the gu:ys here a t the Ca.Pe,

Cooper -

I would sar that the content that we hE\d at the sys t ems briefing was excellent.

I would say the

number we had s chedul ed, I would consic.er the absolute minimum.

I t hink that you should have at an early

date some very thorough,extensive syste·ms briefings and then at a later date , closer to the fl ight some

Pllit8E~~lhhlt

293

additional, maybe shorter , brush-ups on it .

think the people who have done , the McDonnell people and some of our own people and some of the McDonnell people and up at McDonnell is the way to do it .

I think, I want the people to really !mow the

systems, to use the systems briefing.

I don’t

think they can be over emphasized, they’re really 14 . 8 Flight Experiments Conrad

necessary.

Simulations.

Well , we can rule out Denver because we didn’t go there, and MAC, I ’ ll never consider ever flying a flight without a horizontal seater on all the gear .

Cooper

Wait a minute now , we are in flight experiments.

Conrad

This is training.

We got simulation, GMS , Translation

and Docking and at Denver .

This is all backwards

because we didn’t go to Denver.

Oh, okay , simulation.

Well , okay GMS, on flight experiments … we really didn’t do an awful lot of flight experiments in the GMS. Cooper

No , the only thing we used the GMS f or down here was a final stowage revue when we got all changed around. We used it for the REP of course.

A brush through on

the REP. Conrad

We never rigged.

I take it back we did rig.

294

went so far as working out the REP that the D-2 camera wanted to pull it out at real t ime but we never put it in the window.

We riggecl a 16 mm.

Yes, we did use the GMS for all the things that were concerned with the REP which had to do with many stowed items, experiment items . Cooper

Okay.

Translation and docking t raine,~s .

Let me just

say this as far as the simulations on flight experiments.

I really think you can use a mock- up

to greater advantage and most experimnnts than you can the GMS . Conrad

Yes.

I think you are right.

Cooper

I think you are tyi:: g up the GMS in mnny cases over things that you don ’ t need to tie it up for . Translation and docking trainer.

I would like to have

had maybe a little more time in it al though I think we got 99 per cent of what we needed t o get. Conrad

Yes , the afternoon I spent in it was worthwhil e, running the D- 6 camera eq_uipment, takj_ng some pictures and tracking them.

All put ·;ogerther

the GMS and the tracking thing and thn horizontal SEDR up at MAC ended up to good familiarity with the experiments equipment .

14.9 Spacecraft System Tests Cooper

Okay, and at MAC we didn ’ t really run 1 as you say,

-.i @el>,,FID ►T Jl\t

295

t he horizontal SEDR was - around the spacecraft was really the only flight experiments thing that we did on it up there . Let’s see, flight experiments.

Briefings .

Well ,

I think some of the experiments, some were better than others .

Some were lousy and generally the ones

that got there in politically where the lousiest, or they didn I t bother to show up .

I think this is

s omething that should be very carefully controlled by the experiments board.

If the experiment is going

to be chosen the people who are the experiment ers should be forced to come in and give you a good briefing on these, everything ahllt them , or other wise they ought to be thr own off.

Equipment —

now this is along the same line — I think that you need desperately to observe freeze dates for the operation and availability of the experiments. Equipment for the experiments, if it isn’t available i t ought to be thrown off the flight.

I think that

s omebody s omewhere along the line ought to back this . Maybe it has to go t o the LBJ level or something , I don ’ t know .

Spacecraft systems t est … I

personaliy am not very impressed with the

multipl e

296

parallel testing.

I don ’ t feel that the crew really

gets an awful lot out of, out of the spacecraft systems tests anymore because there are so many tests going on at the same time that you can’t really keep a handle on what’s going o:n and really get much of a feel for what’s going on.

You evolve

t o an automated- type thing of calling three scripts at the same time and throwing switches and listening t o quite a complex thing going on.

I think that a

few of the systems tests that still go on such as the ECS test and the altitude chamber type thing are

still well worthwhile, but I think that the parallel method of testing has decreased the val ue of the spacecraft systems test to the crew by great extent . Conrad

There’s no doubt about it, though, in l>eing present you keep them honest on many occasions.

Cooper

Well , that 1 s right.

On the- -it is good in that re

spect , but as far as the training point of view it does give you some certain familiarity with the sys tems too , but I was just pointing out i:hat it was 14.10 Egress Training

decreased over what it used to be. I really thought our egress training wa.s well wort h

while- -

•

297 Conrad

Boy, I do too.

Cooper

I think that was a good exercise-

Conrad

It was wel l organized—

Cooper

I thought it was well organized and well run and just very well done and I felt like it gave us a great confidence in the water situation.

Conrad

I felt real good when we hit the water.

Cooper

Yes, I don’t think there was a qualm in our mind at all when we hit the water that we were right on top of the situation—just no problem.

In fact , I

didn’t even bother listening for l eaks . Conrad 14 , 11

Yes .

Parachute Training Cooper

Parachute training.

As far as I’m concerned I

think if you’ve had any—I don ’ t feel that I missed parachute training at all .

I personally think that .1 s

one you could just delete.

I think sometime, some

where al ong when people come in to the program, they need parachute fami l iarity and parachute train ing.

Of course, I ’ m of the banned school and I

believe very strongl y that we should have actual parachute jump training. Conrad

I do, too .

Cooper

If people think this is too dangerous for this

298

unhazardous occupation. .. 14 . 12 Launch Simulati on Cooper

Launch simulation,

I thought they were very worth

while and I think launch sims that we :~ave with the whol e, with MCC tied in, are extremely worthwhile. 14. 13 Network Simul at i on Cooper 14 . 14

I think net sims are worthwhi l e .

Reentry Simulat ions Cooper

I think the reentry sims we had were ~1valuable. In fact, I would sort of l iked to have had a few more reentry sims.

Conrad

Yes.

14 , 15 Simul ated Network Simul ations Cooper

Sims, net sims.

Conrad

They were invaluable on the REP .

Cooper

They were good for the REP,

Conrad

I think we got something out of the l aunch sims ,

I thought were-

too, a l though that exercise is more fo:~ on the ground , Cooper

Yes, the launch sims had diminishing r1~turns—i t took us a l ong time to cover the grouncl that we shoul d have covered,

Conrad

I think it stayed with the crew and wao worthwhile j ust to get you p l ugged in to the neg ngain and get to hear some of the thing’f! you ’ re going to actually

~ •Ptf;)tNTfrA.Le

299 hear over the net … the reentry sims are more im portant …because it~s a more coordinated effort between you and the ground , and I’m convinced that for any rendezvous situations that some net sims have to be—be run …

16 Zero “G” Flights Cooper

Yes , well , okay, zero g flights, … I ’ m not real ly sure just what value you get out of zero g f l ights.

Conrad

Wel l , I l earned one thing, it was the only oppor tunity that I had before the flight to get—even though it was a bunny suit at the time , a pressure suit up there in zero g and get some idea— opening and cl osing it which we did many times in the flight and so forth …And I think we both learned a little something there.

I would say now I’ve done zero g

in the airplanes and I ’ ve done it in the spacecraft~ and if I f l y again I certainly don’t need to go back and do any zero g work again. Cooper

I really—

Conrad

As far as Gemini is concerned.

Cooper

I reall y didn’t—

FCSD Rep Conrad

Oh , Oh, well that ’ s a different story, yes .

Wel l,

we did do EVA’s …but if I was going to do something

€0PltFt018’fTl!Ar

300 “EVA again, yes,—

Cooper

Yes , I think this zero g airplane plane is well worthwhile for a specific mission, especially mis sion training.

But so far, as just in general .. .

I don ’ t bel ieve it’s particularly worthwhile. Well , it is worthwhile like Pete said, that if a man hasn’t ever made a f l ight before a~~d never ex perienced zero g, certainl y good to f~~niliarize him. Conrad 14.17

Yes, I agree with you on EVA .

Flight Plan Training Cooper

Okay, f l ight plan training.

Well , we n ever did

really have much time to do any real f1ight plan t raining, other than-Conrad

Yes, the onl y thing that we were invol’red in really was the REP and how it was going to go , We l et J erry Jones l ay out the rest of it without us really putting much effort into it.

There rnally wasn ’ t

a heck of a l ot we coul d do along that line .. . Cooper

And I think for long missions this rea:.-time thing is going to go, is going to have to go on, many changes to be made so I ’ m not sure that the over..-all mission needs training.. . I think maybe you might just run spot portions of it on the time-critical of course—

Conrad

301

What do you mean by operational check, you were talking about system checks; in flight?

FCSD Rep

Yes, flight plan training… Operation checks.

Conrad

Thruster ill umination .

Well, I don’t have much

feel for that one way or another other than what I said earlier this morning— yes, I think I don’t know why it’s as plain as the nose on my face but I think we l eaped off the wrong assumption—that everything was going to run right without checki ng and I think that we shoul d flight plan up the first orbit now with more checks in it.

That was a very

poor assumption on this part , the more I even think about it , because it was a perfectly likel y situation to have some part of those three systems to be not working right , and it would have been a simpl e matter to have gone to the secondary scanners and el imina ting the problem at the very beginning that we had , but we weren’t smart enough to know that .

now .

We are

CONCLUDING REMARKS

Crew Quarters Cooper

One comment on the crew area here .

I think that the

crew area here is a real good place to stay and that the kitchen facility we have set up i ~: very worth while , when a real tight schedule is almost a neces s i ty .

However , the bedrooms are not ~:oundproof at

all.

You can hear anything throughout the whole

thing.

Any noise at all that goes on, or a tele

vision or radio playing anywhere thr01:.ghout the whole thing is very easily heard throughout the ent i re build ing.

I say this only because this was one of

t he suggestions that we had before t he place was ever build , that the bedrooms be soundproofed . based on our old Hangar S experiences .

This was

Due to the

fact that heavy construction is going on all the time , this place is completely useless so far as daytime sleepi ng.

There is no possibility of sleep

around here during the day due to the jackhammers and construction work goi ng on .

So , if any shift

work is going on , I recommend that someone keep them a motel room, and sleep during the day at the motel room if you are worki ng night shifts around here and

303 trying t o sleep duri ng the day and run any kind of night tes t s . So far as the people that we had with us that run the pl ace - - I think the place is very adequa tely run . I think one person her e who certainly deserves bouquets is the maid, Joyce , who just can ’ t do enough for keeping all the laundr y done .

She keeps

the pl~ce , I think , very, very satisfactorily clean and squared away . Conrad

Pete , do you have anyi;hing to add?

Well , I didn ’ t hear all of what you said , but I really /

t hought the crew quarters were a great save f or us .

I agree with all the thi ngs about the noises and

everything, with all the construction going on now. I t ‘s kind of hard .

I do thi nk that there is one thing

that I ’ m goi ng to have to go on record as saying we missed in our training, and there ’ s no doubt about about it .

We were so pressed that we didn ’ t have

enough time f or adequate physical training. 15 . 2 Phy sical Training and Aircraft Flying Cooper

There were t wo things ;

we had inadequate physical

training, arid I think we were somewhat short . on airplane flight time .

I would have liked to have had a

f ew more days to be able — when we were do,m here on our last period of time — to got out and just fly

~MMU.L

304 local. Conrad

I flew l ocal once the whole time I was down here .

Cooper

Yes , I don ’ t think I f lew local at al l .

Conrad

No , that ’ s right .

Cooper

And I thi nk , her e agai n , we were caught in the middle of a bad schedu ling situati on, which higher level woul d not allow us to do anythin15 about .

But ,

I think we di d the best we could with t he short amount of time we had .

I personall y f ,~el that we wer e

extremely short on recreational time ru1d on flying time .

We were pretty hard pushed there and on

physical conditioning time .

3 Sea Lab FCSD Rep

Did you a ll ever get to tal k to Scott Jarpenter?

Conrad

Yes.

Cooper

Yes.

Conrad

The l ast day, the second orbit before ·,;e were at r etro.

Cooper

Yes, just before retro.

15.4 Watches and Cl ocks FCSD Red

Do you want to say anythi ng about watches and clocks?

Conrad

I think Gordo mentioned his Acutron stayed within

4 seconds during the whole fl ight and we only set it twice .

305

Cooper

My clock you talking about?

FCSD Rep

It was the one—

Cooper

My own personal Acutron I never reset and it was some 15 seconds off at the end of the flight for the whole 8-day period .

The Acutron on the panel , the

panel mounted Acutron, was—I changed it about 4 seconds .

It ran 4 seconds f ast t he entire flight .

The Omega that I wore was some 2 minutes off the first day and the second day was another l minute and some odd off, at whi ch time I jus t quit winding /

it .

I quit winding it about the third day and

never even bothered using it again .

The stop watch

that I was—that I took along—at the end of the third day was still only about 2 to 3 seconds off. It actually was quite good and I just didn ’ t have occasion to use one and let i t run on down.

And

then I cranked it up for reentry and started two minutes after retrofire .

Your clock over there ran

reasonably accuratel y

your little 8 day clock over

there , didn ’ t i t? Conrad

Eight day clock ran real well.

I kept it on GMT—

the two big wrist watches I carried, I carried mainly for the REP maneuver and didn’t use them too much. I did use them to count down to retrofire and my Glycene

ETIAcbs

306 watch here I kept on G.m. t .

15.5 Miscellaneous Discrepancies Cooper

OK , I have a little list of discrepanc:.es -ti~ that I might just include here.

These are discrepancies

that I noted during the flight and somn of them have been noted bef ore , but I might juHt hit them real briefly. them.

Just to make sure we hav e all of

We lost the stage 2 IPS fuel

gage shortly after launch.

We encountered this

POGO effect at 2 minutes and 6 seconds.

lost communications near SECO on UHF No . 1. many of these have already been explained why, but I just—1 1 11 get these down.

o2 tank heaters.

We lC>st fuel cell
The M..:1 experimer..t pooped out

and also I thought it was objectionably noisy.

The gray interior paint flecks off of the guard bars and off several areas of the cockpit areas and • floats and flecks around on the inside.
The

platform mode was no good for t he burm, and was not holding the spacecraft as it should. FCSD Rep

Let me ask one question.

Did you ever try that

platform control mode on the RCS system? Cooper

No , I didn’t.

Sure didn’t.

I wish I l:.ad , I just-

I guess I had just given it up at that point and just didn I t get around to it .

I should. have.

The

platform mode should work very well.

There’s no

reason why it shouldn’t work very well and I just can’t help but believe it was probably in the OAMS system.

I would strongly recommend unsnapable

legs on a harness like a regular aircraft parachute harness with adjustable buckle-snap combination things rather than the custom made harness that we have.

I think they would be much more usuable for

flight.

The cabin temperature gage failed—

came back in the fifth day for one day and then went back out again.

10 .

We did not use the polaroid

window covers for launch so we don’t know how they will evaluate holding on for launch.

However, they

worked out extreme~y well for flight.

cycles are not observed.

Rest

Too many little things

keep getting thrown in that require two people. 12 .

The PC02 gage was very irratic.

It kept coming

up and indicating PC0 2 up around 1 mm and it did that for a while and then ba ck down.

And, 13.

Tape

recorder quit some time during the fifth day.

That’s

about it. Conrad

We had a couple here—l et ’ s see , di d we get the thing about cabin lights getting hot?

Cooper

And melting paint?

The - l ~ i u g h ! hey will burn your

308

hands and in particular the bright overhead one is very hot . Conrad

One other—let ’ s see, we talked about the purge switches being 3- positioned rather than spring l oaded .

And one other thing we noticed , one systems

glitch which seemed to affect either scanner— out over the Pacific a couple of times we passed some really, really, really big areas of cload cover-, I mean we were almost—the whole visible sky or ground was covered with clouds or a good portion of it and this seemed to give the scanners fits. Cooper

These same cloud.a were that big cloud t hat had all the lightning in it too—later on we- -

Conrad

Well , it may have been .

I didn ’ t make n.ny correla

tion that way, but I, in the daytime , I noticed that the scanners had quite a hard time doiner their job when they were looking at much horizon covered by clouds .

Got very irratic .

I think that ’ s a known

phenomena—with scanners , anyhow, but I just wanted to mention that they did kind of kick up when there were a lot of clouds a.round .

We talked about the

right auxiliary light bulb bug thing breaking off. And I have one question , world where we

There was one place in the

ased at :!Ct a great deal of

rCOW:t0EblTlit

309

gigantic fires on the ground and just out of curiosity I want to know where we were—and it happened on the sixth day at 01 hours 02 minutes and 15 seconds so maybe we’ll be able to find out where we were. That’s all I got, Gordo, how about you , anything more? Cooper

No.

FCSD Rep

Oh, I got— Pete, you mentioned. you blew that oxygen-

Conrad

Blew the OAMS squib—could not hear it blow. no way of telling that it really worked.

Had

You can ’ t

pulse a regulator up and I did and it works just like it does in the trainer .

It gives it a blip, you

know, and you got to keep blipping it up.

And I

built it up to about 325 from about 300 just to see if it would do it and it did. worked OK.

So the system

But I still don 1 t know that the squib

was blown—you know you pulse, anyhow. FCSD Rep

Well, other than looking.

Conrad

Yeah. Well, I thought the squib was in the adapter. No way of telling, I don’t think.

Cooper

I f they are lucky they. might have—( laughter)

Conrad

Well, they found a booster— they might find the adapter.

15.6 Medical Aspects Cooper

I agree completely that the crew area.::iere should be i solated from the medics.

I don ’ t feel that the

medical department should have anythini? whatsoever to do with crew quarters; otherwise, I thi nk the crew should j ust go right ahead and live up to flight day in a motel or somewhere else, because I have a very strong feeling t hat the medical deparu~ent is trying to make a clinic out of this place up here.

I think the crew area should be held completely devoid of medics .

I don’t think they should have anything to

do with the running of the crew quarters .

I think the

crew should establish its own procedurns of whether they’re going to have low residue dietB , or .. whether they’re not going to have low residue diets , based upon recommendations from previous crews , fJ~om previous flight experiences along the way, and what everyone who has worked with it has passed on.

We hope we can

get all this information gathered up ir, a form that each crew coming along can be given a c.ondensation perhaps of all the previous crew ’ s comments on things of this type , such as diets, methods of defecation and urination,

urination systems. drinking water systems . and pre flight set- up type things .

As far as the medical-~

I’d like to hit that specifically.

312 We ·1a.ndeij on• t~e\ ree.Trier at ’ ·”-

mid- morning, carrier time , and we acconplished not one bit of debriefing or operational work throughout that day at all.

We went to bed that night without

ever having done one bit of our own de1iriefi ng of any kind, whatsoever.

The entire day was npent with

the medical community.

I don’t know that we lost

anything there , particularly, but I st:.ll thi nk there are a lot of things you could sit down and start t aping that would be a lot fresher i n ;irour mind. Although, I think with two people on the flight , you tend to jog one another enough that yon don ’ t forget ( .

about things you might when one person has been on a flight.

Now, so far a.s +,ne preflight nedical aspects,

I still have some very strenous object:.ons to it and comments to make .

I think that T- 2 day s physical -

giving t hit extensive a physical at that period of time i s kind of ridiculous.

I think you really drag

a guy throught the hoops there just 2 clays before his flight and completely grind him down on a very, very extensive physical that I don ’ t agree with the medics as being necessary.

And I don ’ t agree with all the

blood- letting that was involved in thin .

I think that

al l t he number of i njections and sticko and reinser tions of isotopic bl ood and everything was completely

313 unnecessary, and , again, was just a matter of r e search rather than anything else .
