1 8.1 Platform Cooper 8.O SYSTEMS OPERATIONS 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 platfor m 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 ,

2 the needles zeroed. It would slowly gyro torque itself and correct out the small errors for fine alinement. Anything to add, Pete? Conrad 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 definitel y 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 hcr i zon should look like at zero-zero-zero and at retro attitude and at minus 90 degrees left and 90 degrees r igh t and at 60 degrees left and 60 degrees r ight and this type thing . I've never seen an a~tual drawin g 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 corne r makes a perpendicular angle to the horizon and you can use that as a roll gage. If you set it up

Cooper And f r om your seat it would look l i ke j t actu all y r olle d right . was Cooper It doesn ' t look h orizont al at al l, but that ' s due to th e fact t ha t you 're sittin g off by thi s offset . Conrad One other thing tha t y ou might say about platform alinement is that if you ' re not on in roll and pi tch, mainl y roll, t his real ly will ea t you up in alinement time . Cooper Roll and yaw are you can be off a out. t he bad errors creator:, . l ot i n and it' 11 corr ec:t Pitch r ight Conrad Not if the other two (roll and yaw) are off .

5 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 bi 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. Right . Conrad You have to take t he time and be careful with the platform alinement, no doubt about i t. ° CSf*fDEt◄ TIAl

Conrad I ' ll comment on this even thou gh we d:i. dn't get a chanc e to do the rendezvous , but even in simula ­ tion , it was appare nt and the l i ttl e bit t hat we did in flight caging the ~latform , gettin g ready for a linement s 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 Fas t Cage cycle is what I should say . I 'll say it's a luxury item but it sure could be helpful .

7 Cooper Conrad Cooper Conrad Cooper Conrad Cooper Conrad 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. Yes , I think you can tell yaw better going backwards than you can going forward . Yes. I don't know why, maybe it was just psychological . I agree with you, I really think you're right. I think you can tell it bett er. It streams away from you a little more . Yes. It was easier to pull in in yaw. I thought it was a little more comfortable feeling . I 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. Of course , we had a little better control system there , it does help. Yes . Mt ◄ FIDE►~TIAL •

8 ~NftDE~~TIAt ·,_ 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 certain l y a t least as accept able as SEF. ORBIT RATE was not bad off at all . We di dn't have any l arge errors in it due to t he f a ct that we had more nearly circular i zed our oroit from t he burns that we did . Conrad We were about at 171 -60 at that time p<=:riod . I 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 jus t t aking a q uick look at zero - zero - zero, not even trying to ali ne thes e. We j ust passed freely through this in dr ifting flight and uncaged the platfo rm right into Or bit Rat e, and it didn't get off five or ten degrees in any of the three axis .

It got about 15 degrees off in roll . Orbit Rate worked very well . 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. Yes . We just never had much occasion during the f light to use FREE. Platform displays . 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 . 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. <!rJ~~FIDEt~TIAL

It's just beautiful . Conrad Yes . Cooper We did a burn right through each one of the poles . I think the controls are pretty simila-r to what they are in the s imul ator . There are t wo exceptions, one of which I think i s valid and which I think may be influ enced by the fact that we had a lot of s low degredation in ou:~ OAMS system . I thought that the PlJISE system in the spacecraft had a lot less torque, a reasona ble amount less torque and it got a lot leB s, as we went along it got less and less and leH s . Conrad Yes .

On the othe r hand, I felt the RATE COMMAND syste m had a heck of a lot more authority in the spacecraft than it does in the simulator . Cooper That RATE COMMAND just flat snaps you in. In the simul ator , when you come around in RATE COMMAND and you let off it will go through 5 to 10 degrees. You have to let off on it 5 to 10 degrees early. By golly , in the spacecraft you didn't have to let off even a degree early. When you let go, it stopped right there just like you put on the brakes. Conrad Yeah. It was good and it was tight . Cooper It was so tight that you almost had to - - Conrad That was OAMS Rate Command. Cooper You almost had the feeling that the OAMS Rate Command was almost bending the Adapt er Section .

We made several maneuvers using this control Eystem and didn 't have any gripes on tha t system at all . As Gordo said we were really impressed wjth the Rate Command system. When you turned around 90 degr ees in crder to get rid of the REP, did you use the 8 -ball ? Yes . FDI 's are on this Gimbal flip bus i ness too, you see . They do that in the trai ner, but they were steady as a rock in the space craft . Yes, we used the FDI's for t he fi ne al ine . Al­ though to get there we used the 8- ball . We had trained to use the IVI ' s . That 's right. We used the IVI ' s , not t he FDI' s . We used t he I VI ' s as the real fine measure of being l i ned up . We used the FDI 's too .

13 Cooper .. Conrad Cooper Conrad Cooper Conrad • You can't use the FDI 's or the 8- ball as a reference in the mission simulation because you have this gimbal flip which just gives you fits . We didn't use Ra te Command very much, mainly just for the burns . In fact , t he burns are the onl y times we used Rate Command. I used the Dir ect syste m several times and I thought the Direct was reall y good . It was good and crisp and you had good authority with it. I had the impression that the spacecraft was a lot more stable vehicle in Di rect than it was in the simulator . Tm t' s right . In t he simulator you tend to sit there and go too much and go too much. When Gordo'd stick a shot of Direct in to go someplace, it never showed up in another axis . An equal shot i n the othe r direction would stop it r i ght now. Yes. The effects momentum of the spacecraft didn ' t seem to be as great in flight as they were i n the ~f:HDEt◄ TIA ~

15 • Cooper Conrad Cooper Conrad Cooper Direct uses quite a bit of fuel also. We did use a little fuel t hat one day. We were doing so many experiments in a row that we had to very rapidly get the spacecraft back to a zero ­ zero - zero or a pitch down 30 pos i tion . When you track one of these targets and come through the nadir and keep on going, boy , you're really smoking towards a rearward direction . You're sitt i ng i nverted BEF. That's r i ght, you ' ve got rates built up going away from you and you 'd have to use Direct to stop those rates, get yourself moved all the way back up here and stop them again . Maybe it'd be so tight that you'd use Di rect to get down and start on it, and then switch to Pulse and track in Pul se and then r i ght back up and start doing something else. Well, we di d eat up a lot of fuel that day, but we got everything done that day. We hit darned near all targets . Di rect i s a real responsive , real fine way to maneuver. 60t~Fl0Et.t:tAt

The Platform took the full 25 minutes to go through the fast heat, and the first time on it was really cold and took another 3 minutes worth before start of the Cage Cycle . After that, it seemed to stick right around 25 minutes to get the platform up and on the line and start into Cage . Right now, I've got extreme confidence in that Platform . I really think it does well. '.Ihe platform did an outstanding job during the entire flight . I t sure did. We fired the OAMS on the pad and it was mushy. You couldn't hear them fire just gas mainly , About the third round of firings however, you could really feel them fire off , they were all good . During flight the OAMS started out very good and in about the third day began to degrade. ~:he f i fth day

So we shut the system down again and had a big talk with Houston about this . We went one more revolution and they gave us some tests to perform on 7 and that 's when we di scovered 8 wasn ' t working . Conrad 'lwo of them quit , within an orbit of one another . Cooper We had already run complete tests on it and number 8 had been working on the previous tests and quit on the next one. 'Ille story of the old OAMS inflight system was that gradually as the days went by there was more , and more that went wrong with it unt i l f i nally at the end we had less than half the thrusters left and they were pretty bad . Conrad I realized a couple of heater blankets were probably out on the OAMS system , but I'm still convinced unt i l somebody convi nces me otherwise, that the thing that shot the OAMS system down, was the decision to turn off the OAMS heater . I had ques ­ ioned the decision in the air to only point that

I still think it was a mi stake be cause I think even with a couple of blankets out, if we'd have kept the ,3ystem warm wi th the rest of the heaters, we'd have never froze them up. Cooper 'llie thrusters themselves were actua lly ·vork i ng because you could actua lly get a glow off of them. There was a litt le bi t of fuel or oxidiier coming out of it and burn ing , but it wasn't getting the proper amount of mi xture ratio . Conrad Now, they could have been dirty . That :ould be it, but it was purely in the valves i n the thrusters themselves because they were putting out thrust even at the end . I f you wanted to hold it i n full D:Lrect w i th 7 and 8 circuit breaker engs.ged , you were getting wet f uel thrust . Cooper Yes. You were gett i ng a littl e wet thr~st .

, 19 of doing experiments on the fifth day , and we had had a little trouble alining the platform. What was happening, appar ently was the number 7 thruster was getting cranky, but we also knew we were vent ­ ing hydrogen and we knew this because we were getting some torqueing out of that . At the t i me Gordo was having trouble ali ning the Platform, we thought it was because the hydr ogen was venting . Finally Gardo said , "There's something wrong with t the control systems . " Once we dec i ded there was something wrong wi th the contr ol system, that ' s when it went just like back i n the simulator .

23 Conrad We didn't hit the direct thrusters long enough to heat them I don't think. I do distinctly remember saying to Gordo "We blew all this junk out of there . " Conrad We' d never seen anything like that before and we'd been up there 5 days and seen all sorts of things . We could see liquid oxygen when we vented it, if we vented i t under the right light conditions . We could see when we vented hydrogen under the right lighting conditions. It would all float by the space craft and at low sun angles, either at sunup or sundown any one of these quantities, ECS o2, CRYO o2, or RSF hydrogen , you could see it come whistling by the space craft. We were continually floating around in these old silver balls of either hydrogen or oxygen. Cooper Okay, well that was pretty well the background of what happened. Some thrusters that had checked out good would subsequently check out bad or be completely inoperat ive as the days went by . So finally we wound up with maybe half of the total OAMS thruster s still operating properly.

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 .

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 . The Secondary Scanner worked fine.

But we never fail ed t o have fairly si zeab le 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 tak e 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 veloc ity , 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 al l t o zeros .

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.

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. We were just talking in our normal tone of voice. And our radio volume levels were extremely low . We were carrying about 4 on our radio volumes . And that was more than adequate volume. 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 . Right .Cooper •

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 .

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, approximat ely what degrees to pitch down.

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 .

Well, I think that coastline is the best, distinctive features on a coastline . Next best are rivers and mountains . Probably, if you can have combinati ons 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 real l y show. Lakes are excellent landmarks. Airports are not as good as lakes and things of this type. Airports tend to blend in a little bit. L~t•s see, color contrast--I've already covered that .

Now the light meter reading loo king 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 a l ways recorded two readings , the reading for the horizon and the black sky, because I didn't really know which one you wanted . With the spot meter the thing just turned out that way.

No 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 .

192 Conrad Cooper Conrad Cooper Conrad C:et<tfilf)Et ◄l l.._4 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, unl ess somebody shows me otherwise on a traces , at least past drogue deploy. It was run­ ning unti l at l east we got Ring B running . 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 . 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 . Yes, they did . They were firing full blower all the way, trying to damp. And they did. They did an excellent

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 Which is fine . You might as well use the fuel up at that point . Ther e's no sense in saving it. Conrad 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. He is going to d.Q.mp before that. So, you might as well use the wire for something else . Use rate command, and if you fly the reen tries just like that , you've got more than adequate fuel in Ring B to poop it away on the drogue and insure

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 switc h 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 the n 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-- Di d you get enough of an oscill ation dw·ing reentry? If you looked out the window .._•as there enough trailing you that you could pr obc,bly damp by looking at this?

Conrad Cooper Conrad Cooper Conrad Cooper • 195 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. He speaks highly of my damping. 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. 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. I really doubt if you'd get very large amplitudes or very much-- Not until you get down there below a 100 ,000. I don't think this is true of a rolli ng 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, as 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. It sure felt that way to me.

It held rnefed for approximately 12 seconds . We were nxactly straight, no oscillations or swings or gyrations on the chute at all. In 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 .,

We looked at movies of these things and we've seen them collapsed on one side, billow out, and collapse, and everything. It 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. We got the see-wawing action. That was it. 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 .

It is kind of a whip action there, more than anything. As long as you are braced for it, it is no problem. And then on landing- - to me that was a su.l'.'prise, because on landing I could hardly believe we had hit . It was so easy . We didn't go under water, didn't splash water, or anything. The windows were clear when we hit . I could see the water as we hit . I could see the chute. When I pur..ched the chute jettison , the chute just floated c-ut in front of us and slightly off to one side•. The windows were clear . They had some conde•nsation on them but not bad. We could see out of them very clearly. We condensed them over a little more just breathing on the inside, I gue,ss. But when the frogmen got there the windows were still clear enough that they came up anc. got up close to the window and we gave them the, thumbs up .

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 . I had all three squib batteries off. I should have left the No . 3 squib battery on. 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 .

203 reason like right here, suit fans 1 and 2--I made a mark out to the side, "faceplate closed", so we would go back and pick them up later. You've got to do it that way. That's all there is to it. It sure did make it easy. Cooper 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.

204 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. And even so, his point is exactly valid. 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.

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. It 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.

We 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 checkl i 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,

Now the Woodleigh si 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 acqui r e the si te and star t t r acking and then we might have gotten them some useful dat a .

And we had planned on this perhaps being the case and we hel d a l l the flexibility that we could in our pl anning .

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 invo l ved, and does not allow the crew time to train .

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 . 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 ­ tional l y. I would l ike to compliment the people who wrote those rules . Experiments 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 fee l 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 shou l d be estab l ished early , agreed to by everybody concerned, and shou l d be hel d very rigid l y to . Unl ess a safety of flight or a significant development occurs warranting a spacecr aft change, the f r eeze date shou l d be adhered to . If you don ' t , ,you affect hardware, you affect al l the previou s and subsequent training a..~d planning involved , and you compromise everything as well as the experiments which did meet the agreed - to schedu l e . 12. 6 Trainin g 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 . I 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. Usually it boi l s down to doing them real time.

There was a tremendous mistake made in the pl anning on our f l ight. We assumed that everything was going to run correctly in the very beginning. We didn't even test anything but the thrusters and that was a mistake. We had the time to make severa l systems checks . You have to do a good platform check. You need to check the scanners . You ought to have a de­ tailed procedure laid out in advance . If we ' d have done that, we'd have lmown that the primary scanner was no good. You should have a computer check , which con­ sists of going into Catch - Up mode, hitting Start COMP, maybe inserting a few numbers and see what they read out . We ran into one computer anomaly where the com­ puter kept running and running and I still don't lmow what that was. Had that occured during the REP exercise we would have really been up the creek.

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. The same ·;hing with the experiments. You' ve got to have that platform.

Can' t say enough about the fuel cells . I just think they did real well. 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 . That thing stayed on sixty o~ seventy hours of the whole flight . That ' s a lot . It must have been sixty hours at least . I think that the fuel cell really goes into a hybernation period when you cool it down. I think it almost hibernates like a 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 . 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. Yes , I think it prob ably would have wor ked. The

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. We had a computer. 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 sit there, shoot the breez,= , talk to the guys out the window and run that tb:i.ng. I don ' t think we became aware of how cri t :i.cal it was until we came down to the Cape and got :m that first sim-ne t -sim . Then we had the ground honking on the horn . They wanted information . We had a spacec raf t 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 chanc e 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 . Eut I wouldn't have made a mistake reading it. 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 wal l. 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 evaluat i 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 extr emely careful with the mission planning peopl e 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 something, or mickey•-mousing around. I think it is going to wind u:;, to be a crew responsibility and that a c ouple 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 rendezv ous , 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 reall y get it down. Cooper Cut i t off at an early date , so 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 probab ly a function of each individual sys t 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. But it sure wasn't apparent to us . 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 retr ofire . There was just so much authority you had trouble getting just small amounts of control forc e until you got used to it. There was so much power there , almost more power than you needed for fine cont r ol . It would be interesting to simulate

I agree with you completely . It seemed to me as though we trimmed a lot nos e 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 .

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 configu ration. 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 have seen displayed in the spacecraft throughout the fl ight . As an example, I h a te to rely on the ground for radiator temperatures or have them call me to heat up a cooling loop. That type of thing is an onboard function . 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 .

Cooper Yes . That salvaged the experiment . Of course he will probably ruin the film anyway, The celes tial 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 , I 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 multitud es 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 const ellati on 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

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 ther e are several pretty good clues and I always lmow when I see Delphinus that the Summer Triangle is near by.

With the accurate star chart updat ed and then finding the stars on there , then you could use them for spacecraft orientation. 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 . I don't know. You would be very lucky , you would just have to see one you could recognize . 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. Well , tracking task.

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 buil d 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 soundpro ofed . This was based on our old Hangar S experiences . Due to the fact that heavy construction is going on all the time , this place is completely useless so far as daytime sleep i ng. There is no possibility of sleep aroun d 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 mote l room, and sleep during the day at the motel room if you are worki ng night shifts around here and

I think one person her e who certainly deserves bouquets is the maid, Joyce , who just can ' t do enough for keeping all the laund ry done . She keeps the pl~ce , I think , very, very satisfactorily clean and squared away . Pete , do you have anyi;hing to add? Conrad 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 Physical Trainin g and Aircraft Flying Cooper There were t wo things ; we had inad equate physical training, arid I think we were somewhat short . on air- plane fligh t time .

It was the one-- 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 pane l mounted Acutron, was--I changed it about 4 seconds . It ran 4 seconds f ast t he ent ire fli ght . 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 just 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 .

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. Just to make sure we have all of them. 1. We lost the stage 2 IPS fue l gage shortly after launch. 2. We enc ountered this POGO effect at 2 minutes and 6 seconds. 3. We lost communications near SECO on UHF No . 1. many of these have already been explai ned why, but I just --1 111 get these down. 4. We lC>st fuel cell o2 tank heaters. 5. The M..:1 experimer ..t pooped out and also I thought it was objectionably noisy. 6. 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. 7. The platform mode was no good for t he burm , and was not holding the spacecraft as it should. Let me ask one question. Did you ever try that platform control mode on the RCS syste m? 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

Conrad 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. 8. 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. 9, 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. 11. Rest cycles are not observed. 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 PC02 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. We had a couple here --l et ' s see , d i d we get the thing about cabin lights getting hot? And melting paint? Cooper The -l~iugh ! hey will burn your

But I still don 1 t know that the squib was blown--you know you pulse, anyhow. Well, other than looking. Yeah. Well, I thought the squib was in the adapter. No way of telling, I don't think.

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 ,

We went to bed that night without ever having done one bit of our own de1irief i 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 anoth er enough that yon don ' t forget ( . about things you might when one person has been on a flight.
