NASA-UAP-D028, Apollo 17 Crew Medical Debriefing, 1972

We're picking up a 12-door show, left off, right in the middle of the dock, and again we're going to do things like nominal as per the checklist, we're going to get the lunar surface checklist check list. Okay, we're going to say so. One power-up and launch prep went well. We did not do the P22 and everything else just went as advertised on the limb. She came up and powered up beautifully. Okay, the lift-off was, again, went normal. We got all, obviously, all our pyros and we lost no change over Parker valves or anything. The only thing that I would like to mention, let the island people get up here, is that very soon after lift-off. We had a pair of loss of calm, a lot of noise in the SPF. It turned out that we were downlucky, but there was something wrong with the uplink. So the CDR watched the, most of the guidance, and we could call out in the blind, altudes and goals and what have you as we've pitched over and pressed on up, but for about the first two or three minutes, I think the lunar module pilot had to concern itself for trying to get combat. Yeah, and again, it was when I was apparently a gutter, or a goldstone, dropped the uplink and when they were getting it back, I was switching on these and for a while there was just completely out of phase, and what they were, kind of, had a continuous downlink. It was a very inopportune time, I might say, because it happened just right after ignition. I think that's something that the encodes are going to be able to clarify, because we certainly can't give you the details. It was essentially no calm in all the antennas. We got into a, they briefed us on a trajectory. We flew into a trajectory that appeared to be nominally actual, a slight out of plane, I believe, and as a result, our tweak had a nine foot per second. It was minus four, minus nine and plus one. We burned out X, Z, Y in that order, and it looked like the eggs out of plane. The indication was about seven feet per second, rule over seven feet. And it looked like we might have had a somewhat a g-sensitive drift in our Y accelerometer and the pings, but the tweak, as it turned out, was an excellent tweak, because our rendezvous resulted in just as nominal rendezvous and a nominal trajectory and profile, as I guess I've ever been involved with. The drift in X accelerometer did not bother us anywhere else in the tracking or in the rendezvous at all. The rendezvous navigation was followed the checklist. We got a radar performed very well. We had auto updates into the eggs. The only thing I might mention here is when it came to making a TPI burn. The residuals in the TPI burn were greater than what I had expected them, and we did not record them because I wanted to get them nulled out just as soon as possible, but they were, and I don't know the tense, but they were minus seven in X, and they were four and four, and I'm not sure whether they were plus or minus in Y and Z, but they were the point I was making is they were larger than I had expected. They were minus seven and four point something and four point something. We reduced those to less than two tenths of a foot per second, and from there on continued to plot right through the midcourses, right up the pike on an nominal trajectory. After that first lash-up, you got any comment about that? The comment was good, a couple comments about the eggs, after about five or ten minutes or early in insertion, I always checked the accelerometers on the after insertion, and they looked really real good, and checked about five or ten minutes later, and I can't remember exactly. I looked and I had accumulated a foot or two foot, maybe a foot and a half per second in X. I saw a gene went free, and I did a gyrocal, and after that there was no significant accumulation in X. I went very well. I did that when I talked to the ground, but I thought I had an understanding of that, and if that was something that you could do, you know. Okay, the, here, I just also mentioned on the TPI solutions, the eggs had essentially within a two or three feet per second a good TPI solution after six marks. The insertion solution was not very good. It was off by a number of feet per second in X, and even more in Z. This was your first 2017 marks, and this was your final change, which you know. The pings of the recycle and pings final were very gross, but a couple feet per second in X. And a pings recycle had, I don't remember exactly the cost for 15 marks in the kind of idea. So I had 7,7,7,7. And there's more data in the data cart books about the various eggs, certain times marks with the eggs solutions. Okay, the mid-course solutions, first mid-course I agreed effectively all systems except eggs out of plane was a little bit high, and decision was made to burn the onboard pings solution out of the limb, which was minus 1.2 plus 0.4 and plus 0.3. We continued to track right up the pike, mid-course 2 came up, and we again compared all the solutions. The eggs out of plane was still a little bit high, and actually the opposite direction from the pings. We had a slight variation in the CSM solution in Z, I don't know why, it came up with plus 5.4 feet per second in Z. So we really didn't get a very good correlation between the CSM and the limb on the second mid-course. But the pings was still performing, the radar was still performing, and based upon our trajectory plot, and based upon our following the nominal inertial line of sight rates, we decided to burn the pings onboard pings solution in the limb, and it was minus 0.4, minus 0.7 and minus 1.6, and from there on out we just continued to follow the inertial line of sight angles and very little tweaking in either in Y or Z, and we just sort of floated right through the breaking gates at one mile, and we took about 6 or 7 feet per second off to hit 30. We met all the gates as prescribed and just came, moving very slowly into final station keeping, went into a formation flight around the CSM, got a good inspection of the spacecraft in the Simbay, the report of which is in a transcript, everything looked good to us. We eventually went over the command module, moved over to the docking attitude that just took his position, his docking attitude, did his pitch and yawm it over, and gave the, gave station keeping control to the command module to pitch and yawm it over and stood by for docking. Okay yes, the command module product proceeding on with the docking, I think one of the more noticeable differences between this docking and the docking with the S-4B is a fact that the SS stage did dance a lot more than the S-4B did. S-4B studies a rock, but you could tell the, we just watched the limb did that because he would change attitude and then you try to follow it and looking on the first attempt coming in, I must have had less than a tenth of a foot per second, just barely closing on it, I'm just taking it nice and easy. Made contact and did not get captured, okay, soon it didn't get captured when it's obviously you're closing too slow, backed off a couple of three feet I guess, something like that, you know all the rates and initiated the closing rate and made, got captured. As soon as we went to capture both vehicles went to a CMC free and you look around and check the barber poles and whatever and look back out there, I had some rates in the CSM and I'm sure now that the, the limb had rates also, you must have had, but we, we did one as soon as we, we went free, so it's just captured the limb went free and the CSM trying to know the rates ended up perturbating the limb and giving us rates. So we finally gave up on that mode had the, the limb go to attitude hold and then once you go to attitude hold then the CSM getting all the rates and we got lined up and attempted a hard docking, no problem, pro retract came back, this time it didn't sound like it was as much of a river fire was more of a, and it was a quicker docking, I put it hard docked and it was as a previous time, again we're taking it, okay, I want to say something about visual sightings during the round of the, I was able to, from the limb, I was able to see the command module in, when it was sunlit, it's somewhere around 100 miles and definitely defined that that was a command module. After the command module went into darkness I could not pick up his tracking light until we were well within about 40 miles, I think this transcript took up more an accurate time but could not pick up the docking light, the round of the light, rather from the command module to where it was within 40 miles and then just a very, initially great dim faint flash. I was able to verify on board that the limb tracking light was working and I finally figured out how it was reflecting off the underside of the EVA handrail on the left forward side of the limb, so I could see the limb tracking light flashing and also whenever there were some particles we took with us that stayed with the spacecraft and you could see the sequential flash off of those particles, there was a result of our limb tracking light. Okay, this is the command module pilot, I've already mentioned in section 11.0 about the visibility of the limb module through the optic. I got down here, this. Anything else to add about run? I retired me in television, I retired from the limb, what was type of way to see, I turned out I took a lot of footage, in fact as we put it on not only the assing mag, we put it on the other mag, we had part of the mag, so that included the same day, right or wrong, we did have a house about on board so we had a lot of house about photography, the rendezvous and some of the surface stuff in the process. Okay, post docking chair, we're going to 13.0 lunar module jettison through TEI, post docking check and pressurization, well first of all, I guess you said you had every last made this time, right? Every last work done, overall docking latches worked, okay? That sounds like there's something to do with the mass and the other vehicle involved. The general comment I want to make about the post docking operations is that throughout the rendezvous, the both pilots in the limb kept their helmets on for dust, keep the dust off primarily, the commander took off his gloves, almost immediately after insertion and flew the entire rendezvous that way, he took years off sometime later. I kept mine on after we'd done a lot of transfer, I can't remember, I kept your gloves on to it, okay, after insertion I did most of my pre insertion work with the gloves off because I didn't want to take the time, I want to get that initial act solution and I could get that fairly rapidly with the gloves and I didn't take the gloves off until maybe 10 or 15 minutes after insertion, but I kept the helmet on all the way through most of the transfer, just to avoid reading the dust that I've had the irritation, sign the irritation on the surface. And the commander kept the helmet on throughout the rendezvous and docking, I took my gloves off after insertion and left them off. Now, we started, when we started getting prepared, as soon as we were a hard dock, the commander took off his helmet and as I look back at that because of the dust debris in the lamp spacecraft, I'm sorry I did it. I could have left the helmet on and I would have had a lot less, not troublesome, but it was just eye in mouth type of irritation, you knew you were in a very heavily infiltrated atmosphere in the lamp because of the lunar dust, although I don't know how much lunar dust previous flights had, but I think we saved a great deal of grief by taping up, by sweeping all the dust we could find on the floor, into the holes and putting our tape covers over those holes, I think that had to help a great deal because there was an awful lot of dust on the floor that we didn't see. So I had, the commander had his helmet and gloves off throughout the entire transfer. Basically, the way we handled the transfer was the way we had planned the, I think the lamp pilot did most of the preparation of the gear in the, in the lamp in the commander stayed in the tunnel and passed things on and the inventory was going on on the command module side and on the lamp side both. We backened each other's suits the best we could and everything else that got supposedly transferred un-bagged or un-covered. This is young things, part of the scene of these comments to the contrary, I think we got things remarkably clean and it wasn't an awful lot of dirt in the landmark that was coming back. Oh, that's true. I didn't want to do that. Contrast, he may have thought it was dirty, but I was surprised we were able to keep the level of the part of the expression, contamination of the command module down. That atmosphere that the commander was referring to in a lamp after he took his helmet off, I could go halfway through the tunnel and stick my head up into the command module and it was totally refreshed, un-proluded atmosphere up there and it never did get polluted. I think having a vacuum cleaner running in the lamp had a lot to do with keeping the flow in the other direction until we're out there. We never did vacuum in the command module because this wasn't necessary vacuum in the command module. And the suits were noticeably cleaned by the vacuum cleaner. You could tell you were pulling stuff off them all the way, still dirty and every other stuff from the time we handled them we got our hands dirty, but I think most of the pre-desk was taken care of. We effectively stayed on a transfer list. I say effectively throughout the transfer, however, some things got transferred out of order and got temporarily stowed in the command module, but we effectively used the transfer list as a, not as a cookbook, follow recipe type of thing, but as an inventory list. And we inventoryed it several times from both ends and found out that we were satisfied we had everything transferred and then pressed on with the lamp close up. The lamp close up went nominal. We got back into the command module and the commander closed out the lamp, and for convenience the commander effectively went back and closed out the lamp hatch, put in the command module hatch. Because of the slow tunnel vent, or the long duration of tunnel vent, the commander stayed in the tunnel in the LFP in his seat, in the CMP in the left seat. We suited up and got prepared for our, for integrity check as soon as the, as soon as the line tunnel vent was complete, and we were satisfied with integrity of the hatch, we went into the, to the, to the, uh, suit integrity checks. Yeah, this is CMP. Let me make another comment on a tunnel vent time. I bet it must take, and I'm not sure if this is correct, but I bet at least, uh, three or four times longer than the simulator is for the tunnel vent, uh, move. And I think that's going to be applicable to Skyland because of the little docking, uh, they're going to have to vent before the end of the dock, okay, it took quite a, it took quite a while. But tunnel close out was easy. We had no, uh, no drill, no bro, which we were stowed, uh, uh, in the, uh, for, uh, uh, going through the rest of these, uh, mine triggers, uh, under, under, under, under John Josephson through T.E. I, we just followed the checklist and it all seemed to happen just as advertised. Well, we got a little bit intrigued with the, uh, the lungielson, you know, at this time it was, it was great and it just sailed out there nice and pretty, and we got a lot of good pictures of, uh, uh, where we should have been maneuvering, and we ended up, uh, getting into P-41 after the, for the set burn, uh, a little bit of light, but that's no problem either, because we're just trying to reserve those in P-41 and, and got a good set burn. I, I want to make a comment that I think cleaning control, uh, in a command module, uh, was excellent considering all the dust and all the dirt, uh, that just seemed to adhere to everything in a limb. When we got back in a command module with the exception of the suits, and with the exception of the LNP and the CDR, uh, everything, uh, was clean, uh, and that's for the most part is because everything was bad before we brought it over, bag and zipped. We never did open anything, uh, once we got it zipped up, so the command module stayed and I think that suit fan filter is probably going to be very, very clean state exceptionally clean throughout the remainder of the flight. Let me add a bagging, uh, and the de-contamination bags, I made a special effort, asked for, uh, request, uh, pre-launch to, uh, pull those zippers as tight as I could, and they should be pretty tight-seared. Okay. Okay. Or if we don't have a gauge in high gain, why don't you pick that up? Okay. I'm already, uh, from, except the TEI, I have no, uh, no comments. High gain and always worked good. Omnis and SPAN were good. Uh, photography, uh, went as advertised, we have a lot, uh, of, uh, targets of opportunity. And, uh, some day operations, uh, have been mentioned before. Let me just make one gross comment about the way we handled it as a three-man crew at some day operations, which, after, uh, yes, sir. Didn't we? Yeah. Okay. It's covered. I like it's covered. I don't know. I think I did say so. Yeah, we did. Okay. Okay. The TEI updates, no, no. Section and start checks, uh, were good for TEI. I think Commander's Master Lyman, every one of them, all through the flight, which made me feel very good. But you kept trying again. I made sure I got it. I made, I made sure I got it. I was last few. I was going to change any mode of operation. I'll tell you that last one, uh, where we're entry was the last one. I made sure I got it on TV, yeah. Just make you guys feel at home. I figured you'd think I didn't do it right if I didn't get the Master on. The, uh, TEI, a half G or whatever we were pulling there, uh, was, uh, seemed like more than that. Sure did. It seemed like it was really pushing you back in the seat. Yeah. Ron and I both, I think, started out holding our heads up and eventually relaxed them back on the, on the couch. I guess we must have had the spacecraft pretty well stowed or tied down because, uh, as I brief the CFP and LNP and as I recall, those kind of burns back in Apollo 10. Lots of things started moving through the spacecraft and find their due, uh, on the, uh, on the aft, uh, end of the spacecraft because of the G load. And much to my surprise, uh, all we had was initial thought as we moved away from the station and we didn't have any gear coming from any work flying through the spacecraft. So we must have cleaned it up pretty well. I found, I got a, uh, caught a white tag wet wipe. A white tag wet wipe. But other than, than maybe one or two of those things, uh, in looking back, uh, I would have expected more gear to come from somewhere but, uh, we prepared for those burns pretty well. Well, that reminds, brings up, uh, another point that reminds me though, is that there, is always water condensing on easy use, uh, you know, the pipes and whatever you're back in there when you get back to clean the suits of the return belt. And, uh, when we put our suits on for the EVA the next day, your suits were noticeably wet. And, uh, also when I pulled the PGA bag up, it was damp down underneath the PGA bag. So I think, uh, as a normal procedure, we should have, uh, either after the burn, probably before the burn, made sure that we wipe out the water in the LAB somehow and do that. I wasn't really aware of our suits, for example, put them out, but I was not aware. I could look down there and I could not find any real water down in the, uh, down there. It's just an ECS. Yeah, an ECS, there's always water down there and ECS. It's just a screw, that's where all I came from. But, uh, it's not a flow of water. Like you said, it was just damp. And almost as if it was colder down than the LAB and water was condensing on all over the suit. It wasn't as if they were in a flow. Yeah. Okay, I think that covers, uh, right on through, uh, TEF. Let's see. Yeah, the one thing I want to mention on TEI is that, uh, again, the simulator is set up such a, uh, in the roll dead band. It goes over to one side of the roll dead band and just kind of stays there. And, uh, during the DEI burn, uh, it was bouncing back and forth from one side of the dead band, or over to the other side of the dead band. And when it's bouncing back and forth, the roll rate is up around, uh, all four tenths, uh, four tenths of a degree per second. Marking back and forth across the roll. Okay, 14.0 transverse coast in the thing, and I just realized we'd neglected this anywhere about systems, uh, like I mentioned chlorination at this point in time. I think without fail, do you ever talk about it? No. I think without fail, almost every chlorination leaked. Uh, sometimes larger quantities of water, other times just small quantities of water, and I'll tell you where it leaked. Water are chlorine. Well, well, it's chlorine in your chlorinate and, uh, in buffer or water when you withdrew the buffer sample here. But where it leaked was appeared to me to leak within the ampoule itself around the bag because it was the chlorine, the cylindrical chlorine dispenser that was continually wet. It was not the, uh, it was not where the dispenser fit into the needle or where the, uh, needle adapter fit into the spacecraft. It was within the barrel chlorine dispenser itself. And, uh, we continually, chlorination was, uh, was a case of, uh, of always cleaning your hands with chlorine because you always had it available down there within that dispenser. And in some cases you had larger quantities of water that had to be worked up with, uh, with a tissue. That plagued us throughout the whole mission. It turned out not to be a serious problem because we learned how to handle it. But, uh, that was one system anomaly that never had really been brought up. Okay, look, let's see, uh, uh, CMP, let me amplify that a little bit. In, uh, two cases of almost positive that when you put the thing on the bayonet fitting and crank it on there, it did not puncture the ampoule itself. And the reason I can, I believe that's correct is that, uh, when you start to, to crank the, uh, outside of the cassette down to push the chlor on into the, into the water system, it was very hard to turn. And if you, if you tried to force it, you could force it on down there. And I'm sure that's a good way to, to break an ampoule on the thing. And if you take it, I just, uh, in two cases, took the bayonet fitting loose again, and put it back on there. And in both cases, uh, then you just try to squeeze the chlor on out of the ampoule into the system. And it would turn easier. But it's still hard to, to totally hard to crank that thing down. But, uh, we did not, uh, we got the chlorination done. We didn't miss any injections of chlorine, and we didn't miss, uh, we didn't miss any of the buffer samples. Uh, so I guess we got the job done. It was just a little bit messy. And chlorine was evident in, because, uh, the CDR eventually peeled all the outer skin off his right hand, and I'm convinced it was due to the chlorine and had nothing to do with the EVA. Boy, you lost a little, a little flash. A little skin on the EVA. Transurist Coals. Systems navigation. Let's press on and see what we can say about that. Do you want to go on? Okay, uh, well, let me see how much transurist Coals we're going to do. Let's go, yeah, let's go through up to the CSMEBA anyway. Okay. The first thing I want to mention is passive thermal control was, uh, at what I would call unusual attitudes, because of the UV and IR requirements. You know, these unusual attitudes did two things. They, uh, they put us, uh, they required us to re-maneuver the spacecraft several times, and exit, enter and exit PTC several, several times, which in itself was not a problem. It was just an additional, uh, coordination. Uh, coincidentally, most of these particular PTC attitudes were within 30, certainly 45 degrees of gimbalock most of the time. So we were looking at the red apple. Good portion of the trip home. Uh, but they also, uh, some of those attitudes where you actually were not in, were in attitudes, and or PTC at these relatively unusual positions. Uh, change the, uh, the equilibrium heat load on the spacecraft. You could see it in, uh, in RCS, uh, quad temperatures were all right, but you could see it in helium packaged temperatures, and most notably, you could see it on the change in, uh, condensation from the tunnel hatch to the, uh, forward hatch. The tunnel hatch eventually from most of the way home ended up to be very dry. Uh, in the, uh, about the second day out on the way home, the, uh, the, uh, for the, uh, uh, the main, uh, center hatch. Uh, got soaking wet to the point that, uh, Avid took a dry rag and wiped off some of the, uh, latch components and some of the, uh, gearbox components, externally. Not that it did any good, but there was just that much water on it. And I, I think this is all due to the, uh, PTC attitudes required for the, uh, Simba experiments on the way home. Oh, it's colder in the spacecraft, too. Oh, yes, it was colder. Not as cold as the commander thought it was. That's right. Cold enough to warm up. On the commander's orders. And I just mentioned, we warmed it up with the ground suggestion of an extra inverter and, uh, going to manual on the 10th, 10th end. I think we discussed that. Ron, all your, uh, all your, uh, your rough map changes. Uh, you're, uh, torquing, platform torquing, all those, uh, went very well, I thought. I'm great. We were, uh, we were. The, uh, and I, all the way back home as the, it was just changing attitudes, changing attitudes, changing attitudes with the exception of the EVA day, which, uh, we'll cover here shortly. Yes, I'm EVA. Okay, on EVA prep. I think the only anomaly we came across was the, uh, CMPs. Uh, well, let's see, on EVA prep, we really didn't have any. We didn't know anything at that point. I mean, I was going to say on the CMPs, uh, top area. But the EVA prep went, uh, right down the line, essentially, it was all, uh, well laid out within the, uh, experiments checklist, and we checked things off as we were. And, uh, stayed pretty much on the timeline. We started about a half hour away, and stayed a half hour away. We, uh, we, we started out, we were half hour early throughout the whole thing, and we lost that half hour, and opened a heads just about it, and turned to you, man, exactly on time, and I can't remember a small little something chasing down. Comp carrier change. Comp carrier change. We lost that half hour during a comp carrier change on its own. Uh, Ron, I'd like to add that, uh, post EVA, that, uh, I think one thing that helped us, uh, immensely on what ended up to be, I think, a very fine, uh, entry storage was that, we sort of, uh, backed off after the EVA, and, uh, and, uh, took a long, good long was that the long range storage, as well as the post EVA storage, and really effectively started housekeeping, cleaning up the cabin, and effectively stowing some of the articles that were not going to be used any further in the mission for entry. At that time. At that time, sorry. That entry storage really started with the post EVA time frame period, and I think that really helped us out in the long run. Okay, I think, uh, we should mention how we got out of the suits. I think for me that was a pretty important, uh, way to get things done. The only change, the only change to the, to the, uh, prep and or post was the order in which we doft and don suits, because it was very evident that there were certain convenient ways because of the way the students were stowed, and, uh, the way people fit into the checklist that we, uh, when we don the suits, the commander got down. You can't, you're going first. First, and I didn't. Then the LMP, and the NSCMP got down last, and it worked out very fine. It was plus the CMP. It had less work to do in his suit, which also aided him in the long run. When we doft, I went first. The LMP. Yeah. That was definitely first. I'll be the new one. Then the CDR. And then the CMP, and that wasn't exactly what it was called for, but that's the way it worked out. That's the way it worked out the best. And we stowed our suits, and he'll shape back prior to putting the center couch back in, which was, uh, another good decision, I believe, uh, in helping us get the suit stowed back, and it'll shape back. Go ahead. Okay. Let's go on down the cabin depress. Uh, no problems. The normal, uh, depress hatch opening. Uh, even though the hatch was completely, uh, or the cabin was completely depressed, I think we're reading zero pressure on the thing. As soon as I opened the hatch, there was enough residual pressure, or something, inside the spacecraft that it actually tended to pull the hatch out of my hand. The suit is bleeding into the cabin all the time, so you never truly get zero. That's right. You never truly get zero on the thing, but the dump valve was still open. And, uh, if I had not been hanging on to the hatch, it would have blown it all away. Or on to give you an idea on that's, that's exact. That's not unexpected, because it's exactly what we had on the lunar surface. We completely, completely dumped the lamp, and I'd still have to break that hatch loose and hold it open about six or eight inches until things just bent it, and then I could leave go of the hatch and open it all the way. If I didn't, it would slam back closed. Oh, yeah. Different doctor. So it was basically the same thing. You got to open it, but it really let things get down to zero. Okay, well, when I opened the hatch then, all of the, uh, excuse me, all the little ice crystals and everything started flowing out. Uh, a pen floating by, something else went floating by, I wasn't quite sure what it was. But, uh, there's all kinds of little particles and pieces start coming out through the hatch. But I sure didn't see, I looked specifically for the scissors. I, uh, I didn't see the scissors go out that hatch. I hate to say it. The other one by my watch. I didn't, none of them went by me. Ron, I'd like to say that they went off the hatch, but I sure didn't see them go. All right. I caught the one thing that went, started to go by me and put it in your pocket. You got that? Okay. Okay, the, uh, what's the, uh, all the particles and, uh, jumpers all the way, then you just push the hatch open. We had disconnected the, uh, counterbalance, uh, with the beat, the tool be there, so that, uh, we locked the hatch in the open position, so I just shoved it open. And it went beyond the, uh, center position and, uh, locked in the open position with no problem. Egress, uh, had a tendency, I guess, to, uh, just like, uh, any other thing. It seems like you want to fold up. And I had a tendency to fold up against the, uh, MDC and had to consciously duck and, uh, get as close, my face as close as I could to the bottom of the hatch, in order to, uh, get past the, uh, get the OBS past the MDC and get on out. TV and deck installation, uh, were crying. I could hang on with the right hand on the, uh, hatch. Uh, the great big, uh, D handle on the hatch. And, uh, with the TV pole on the left hand, and it worked out real fine. Just, uh, stuck it in there and then lined it up with the mark and, uh, make sure it was, uh, locked in or clamped in. And then, uh, climbed on up the pole to, uh, turn the TV on, or turn the, uh, deck on. And it was, you couldn't see the light. I couldn't see the light on a thing, but you could feel the camera running once you turn it on. You could just touch it and you could feel it vibrating a little bit. The, uh, lunar sound are cassette, uh, retrieval. Um, I think, uh, they should be on the onboard, uh, or on the, uh, air-ground tapes. As I was describing, uh, most everything was going on. There's no problem. The pan camera cassettes were next. No problem on the pan camera cassettes. The pan camera, uh, it's obviously a bigger mass and it's, it's, uh, quite apparent when you try to move, move that big mass around. That it is heavier, it weighs more than the other thing. It's easier to move, but it just takes a little more effort to get it started. And you know that if you ever get it started in one direction, it's going to keep on going. You have to stop it. So I just, uh, moved everything real slow, tried to keep it down to control. Mapping camera cassette had the same, uh, problem I had in the, uh, in a Simba, uh, C squared S squared getting the, uh, the, uh, thermal cover off. It's stuck underneath the mapping camera. It weighs around a timmer, uh, door. But, uh, there was no real problem. Yeah, I was, I had to feed it on the shoes. Just give it a big jerk and then it finally came off. Simba inspection, uh, that's all covered in the, on board, uh, I mean, air ground tapes. TV and DAC removal, uh, again, was real simple. Just had to squeeze the, uh, the lever and TV came out and it was easy to, uh, hang on with one hand and maneuver the, uh, TV around and point it toward the, the moon. Because I didn't have to worry about trying to get into the sun. When I tried to, again, hang on with one hand and point the TV around toward the earth, it was, the earth was, well, maybe 10 or 15 degrees, probably 15 degrees from the sun. And I would try to be a little more accurate on the thing. When I did that, then I lost, kind of effectively really lost control of the, of the, my body position because I was trying to, uh, I think, maneuver the camera. And they just, you need both hands to maintain your body control again. So, rather than try to slice the camera through the sun or something like that, it gave up and trying to point the, the camera out there. Calm during EVA, it was loud and clear for me throughout the, throughout the EVA. There was a lot of background noise that hissing, uh, of the airflow. I'm sure that was probably kind of over the, uh, the box circuit. But don't you think anyone had, didn't appear to me that anyone had any trouble on the ground region? I think one of the big advantage everyone would be on pity that one thing we did, because it was bothering him, and first we turned the air mopox sensitivity down about two notches. And apparently that really improved the conformism. I had that impression from the ground. I don't know if it did, if it made any difference. I got the impression that the did help. Calm into the cabin was excellent. I never had any trouble understanding. I had to hissing in the background, but we did. Yeah, I thought it sounded much better than I remembered other flights. On the aircraft. Well, our CMP made more noise than that. I guess he's the wrong word there. It was clear. Clear. Ingress seemed to me like it was easier than egress. Yeah. For some reason. Task closing was harder than I anticipated. And I guess maybe this is the same reason, is that I must have been exhausting into the cabin all the time. And just that light, the hash would come closed within about an inch of closing on the outer edge. And then it took an effort to pull the house closed so that you could activate the latching handle. So that you could get the latches over center. Of course, once you got the first stroke of the latching handle, you got the latches over center. Then it's really easy just a couple more cranks on the hatch. On the hatch closing. The cabin repressed was not enough. On the end, my contact here was LNP. All I did was work in the hatch area. And I want to emphasize, I mean what everybody has always said is that you do your best work when you take things slow and easy and just let yourself move yourself in small increments to where you want to go. You can turn and dip and break yourself out. And I think it's also useful for any cabin to hatch or port operations to have somebody else available to push you out on your tether as far as you want to go and pull you in. It just eases the operation of being able to do this occasionally from here. But what the client with the scruts and everything available there, there was never any feeling that I didn't have a way to control my body position. Sometimes it took a few seconds to get it where I wanted it, but it was clear. The one thing, invariably every time I went back inside, I had this 90 degree disorientation feeling for a few seconds until I got the perspective of the cabin again and said, okay, that's right. And I get back in. And then I go back outside and come back in again. And once again, it seemed as if the cabin had rotated 90 degrees to my perspective. And it's just something that's no problem. It's just a change of perspective for some reason that I experienced several times. I guess the biggest problem working in that angle for me, some angle or attitude was I had the sun for the face. You had the sun in your eyes most of the time. And it sort of made it hard to look in detail and see what you were doing. You were clear and there. I could see every major offer doing it, but if I specifically see details of this. One point I wanted to make also was that I had no awareness whatsoever that I had an umbilical on my back. I never got the feeling that the umbilical was tugging on me, restricting my movements, or anything. I didn't even know it was there. And did you observe at any time did the umbilical ever get taggled around? No, my feeling of the umbilical was easy to tend. And I frankly don't remember a single time and I had to clear it. There may have been one. Somebody had a vague impression that one time I asked you to hold up. Or maybe I didn't say anything. I just moved it away from a handhold or something. But the umbilical was very, didn't tend to snake around. You seem to have everything you needed on it. I didn't even know it was there. That's the point I was making, is it really? Being tied to the umbilical does not restrict your movement or give you a feeling that is restricting your movement at all. Suit doffing and storage, I think we've already discussed that. This is continuing on the EVA part of it, but I don't know, this is just a different section here. Suit doffing and storage. We've already mentioned the suit doffing and storage. The light flash phenomena. We drove for an hour and never saw a light flash. That was the second round. The second round. I don't know where that transfer is. He didn't rest in exercise. No, let me add to the light flash. The next, a bad evening, I guess it was. I did see them again, honestly. Okay. So, I did too. So, that was just that period. Apparently during the actual experiment, if there's some reason they weren't. I think we've discussed the eating, resting. Yeah, exercise covered already. Cabin atmosphere. The one thing that I don't think we've ever mentioned yet, and I think should be noted, is that we never really utilized the waste storage vent to get rid of any odors out of that waste storage compartment. And if you kind of drifted over in that area, it was always a crime that you were in that area. You got real close to what I thought. I don't know. I don't know. I guess maybe I did when you opened the door, that's when you really noticed it. The cabin, generally, turned over the atmosphere in pretty good style. It got saturated sometimes with gas, and it took a few minutes. But once the source of that gas was plugged up, the cabin did a good job of recirculating cleaning. I think it did, I think. Real good. Flight plan updates were super. The flight plan was excellent. Anywhere hell to a minimum, and we really didn't change any part of the entire flight, except a few dates and times, and what have you hearing attitudes. But other than that, it was really at a minimum. Let's say the entry preparations really began after EVA, and continued off through the next day. We had very little final storage to do on entry morning. Just those things that we had to leave unstoed until we got out of our sleep restraints. We basically just had to tie the big bags down. I wanted to in 7 and 8, and final entry preparations went by the checklist. If anything, we stayed about five minutes ahead throughout the entire checklist, including separation and activation of the command module RCS, and picked that five minutes up, of course, right at 05G, which came on time. Communications, I thought, were very good through that period of time. We were through Orion the last couple of minutes, part of RRT. And I understand now that the ground heard everything we said right on through Blackout, into Blackout. And then I understand we came our Blackout. They still had Orion, and they could read us. And we could have read them, but they never transmitted anything. Oh, that was a little cut. I'm not going to take care of the time. I can't think of anything at all. On the quarter, it's actually we got horizon and moonset. Without any problem of looking. But we had a lot on the over within seconds of the actual time. We were all within seconds, and in CMS, I'd always looked for the 2G when the quarter of that would go out, though. I didn't even notice it. So I must have been watching something else. I must have been checking the EMS.
