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

We're picking up at 12-0 liftoff rendezvous and dock . And again , we're going to , where things went nominal , as per the checklist , uh , we're going to , uh , Get the lunar surface checklist here . Yes . OK , we're going to say so . Let them power up . And launch prep , uh , went well . We , uh , Did not do the P22 . Uh , And everything else just went as advertised on a limb . She came up and powered up , uh , beautifully . Anything in there that's worth going . OK , the , uh , liftoff was , uh , is , again , uh , went , Went to , Normal . We got all the , obviously all our pyros , and , uh , we lost no changeover Parker valves or anything . Uh , the only thing that I would like to mention , uh , let the LNP pick it up here , is that , uh , very soon after liftoff , uh , we had , uh , apparent loss of calm , a lot of noise in the SPN . Uh , it turned out that we were down lucky . Uh , but , uh , there was something , uh , wrong with the uplink . So , uh , Uh , the CDR watched the , uh , most of the guidance and , uh , we call out in a blind , uh , altitudes and goes and what have you as we pitched over and , uh , pressed on up , but for about the 1st 2 or 3 minutes , I think the , uh , lunar module pilot had to concern himself with trying to get combat . Yeah , and again it was another apparently I got her , or uh gallstone . Dropped the uplink and then when they were getting it back , I was switching on these and for a while there it was just completely out of phase . And , uh , But they were , apparently had a continuous downwind . It was a very inopportune time , I might say , to , because it happened just right after ignition . I think that's something though that the , uh , Encodes are going to be able to clarify because we , we certainly can't give you the details . It's just there was essentially no comm on all the antennas . We , we got into a , uh , they , they briefed us on a trajectory . We , uh , we flew into a trajectory that , uh , that appeared to be nominal . The ag showed a slide out of plane , I believe , and , uh , as a result , our tweak at , uh , 9 ft per second . It was -4 , -9 , and plus . We burned out X , Z , Y in that order , and , uh , it looked like the eggs out of plane , uh , indication was good . About 7 ft per second , a little over 7 ft . Uh , and it looked like we might have had a somewhat of a G sensitive , uh , drift in our , uh , NRY , uh , accelerometer and the pings , but , uh , the tweak , as it turned out , was an excellent tweak . Uh , because our rendezvous resulted in , uh , uh , In in just as nominal a rendezvous and a nominal trajectory and profile as I guess I've ever been involved with . Uh , The , uh , the drift in that accelerometer did not bother us anywhere else in the tracking or in the , uh , Uh , in a rendezvous at all . Rendezvous , uh , navigation was , uh , followed a checklist . Uh , Uh , we got , uh , radar performed very well . We had auto updates into the AGs . Uh , the only thing I might mention here is when it came to , uh , To making a TPI burn ? We , uh , Uh , the residuals and the TPI burn were greater than what I had expected them , and we did not record them because I wanted to get them , uh , I wanted to get them , uh , nulled out just as soon as possible , but they were , And I don't know the tents , but they were -7 and x . Uh , and then they were 4 and 4 , and I'm not sure whether they were plus or minus in the Y and Z , but I , they were , they were , the point I'm making is they were large , larger than I had expected . They were -7 and a 4 point something and a 4 . something . We , uh , reduced those to , uh , less than 2/10 of a foot per second , and , uh , from there on continued to plot right through the midcourses , uh , right up the pike on a nominal trajectory . Uh Communications after that first , uh , lash up , you got any comment about that ? Uh , the comment was good . Uh , a couple of comments about the eggs . After about 5 or 10 minutes , uh , or early in insertion , I always check the , uh , accelerometers or the after insertion . And they looked real good except about 5 or 10 minutes later , and I can't remember exactly , I looked and I had accumulated a 1 or 2 per foot , maybe 1.5 ft per second at X , so gene went free and I , uh , did a gyrocal and after that there was , uh , no significant accumulation in the . And that went very well . I did that without talking to the ground , but I , I felt I had an understanding with him that that was something that , uh , we could do without . OK , the , uh , here , let me just also mention on the TPI solutions , the ags had essentially a within 2 or 3 ft per second a good TPI solution after 6 marks . The insertion solution . Was not very good . It was off by , uh , a number of feet per second and X . And even more and see . so This was your 1st 1 , 17 marks , and this was your final . It didn't change much at all , did it ? No . The pings recycle and pings final were very close , within a couple feet per second . And X right . Yeah . And a pings recycle , uh , had , I don't remember exactly the cause for 15 marks . I think I , uh . You had I had 1717 17 . Uh , And there's more data in the data card books about various egg at certain times marks with the egg solutions . OK , the midcourse solutions , uh , first mid course , uh , uh , agreed , effectively , uh , all systems except , uh , Uh , eggs out of plain was a little bit high . And the decision was made to burn the onboard pink solution out of the lamb , which was -1.2 + 0.4 and + 0.3 . We continued to track . Right up the pike , uh , mid course two came up and , uh , we again compared all the solutions , uh , the eggs out of plane was , uh , still a little bit , uh , high and then , uh , actually the opposite direction from the pings . Uh , we had a slight variation in the , uh , CSM solution in Z . I don't know why . Uh , it came up with +5.4 ft per second in Z , so we really didn't get a very good correlation between the CSM and the LEM on the , uh , second , Uh , mid course , uh , but the pings was still performing , the radar was still performing , and , uh , based upon our , uh , trajectory plot and based upon , uh , our following the nominal , uh , inertial line of sight rates , we decided to burn the , uh , Pings , on boarding solution , uh , in the lab . And it was -0.4 , 7 , and -1.6 , and from there on out , we just , uh , continued to follow the inertial line of sight angles and , uh , uh , very little tweaking , uh , In , uh , either in Y or Z and we just sort of floated . Uh , right through the , uh , Breaking gates , uh , at 1 mile , I think we put about , took about 6 or 7 ft per second off to hit 30 . We met all the Gates , uh , Uh , as prescribed and , uh , just , uh , came , Very moving very slowly into , uh , final station keeping , went into a , uh , A formation flight around the uh CSM , uh , got a good inspection of the spacecraft and the Symbay . The report of which is in a transcript . Everything looked good to us . Uh , we eventually maneuvered , uh , the command module maneuver to the docking attitude . The 1 just took his position , his docking attitude , uh , did his pitch and yaw maneuver , and , uh , or gave the , uh , gave , uh , station keeping control to the command module to pitch and yaw maneuver and stood by for . For docking . OK , uh , Commander Marshal pilot proceeding along with the docking . I think the , uh , one of the , More noticeable differences between , uh , this docking and the docking , uh , With the S4B is the fact that the SN stage , uh , Dead bands a lot more than the S4B did . Uh , S4B is steady as a rock , but you could tell the , uh , just watch the limb . Dead band because it would change attitude and then you'd try to follow it and looking on the first attempt coming in I must have had less than 0.1 of a foot per second just barely closing on the thing just taking it nice and easy , made contact and did not get captured . OK , as soon as it didn't get captured when it's obviously you're closing too slow . I backed off , uh , oh , what , a couple of 3 ft , I guess , something like that , renewed the rates and , uh , initiated the closing rate and , uh , made , got captured . As soon as we had to capture , both vehicles went to CMC3 . And you look around and , uh , uh , check the barber poles and whatever and look back out , and here , uh , I had some rates in the , uh , CSM and I'm sure now that the , uh , the lam had rates also . You must have had . Well , we , we did one as soon as we , you went free . See , as soon as captured the lim went free . Yeah . And then , uh , the , the CSM trying to null the rates ended up perturbating the limb and giving us rates . Um-hum . So , uh , we finally gave up on that , uh , Mode had the , uh , the lamb go to , uh , attitude . And then once you go to the hole , then the CSM can all the rates . And , uh , we've got it lined up . And , uh , attempted the hard docking , uh , no problem . Probary tract , uh , came back this time , uh , it didn't sound like it was as much of a ripple fire . It was more of a . And uh it was a quicker . Docking . A heart , a quicker heart doc than I was , uh , the previous time . You got any more tape ? OK , yeah . OK , I wanna say something about visual sightings during a rendezvous . Uh , I was able to from the limb . I was able to see the command module in , When it was sunlit . At somewhere around 100 miles and definitely defined that that was a command module . Uh , I , after the command module went into the darkness , I could not pick up his tracking light . Until we were well within about 40 miles , and I think this transcript had got more an accurate , uh , time , but could not pick up the , Docking light , the rendezvous light , uh , rather from the command module two we were well within 40 miles and then just a very initially very dim faint . Uh , 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 , Lam tracking light flashing and also when there were , there were some particles we took with us , uh , that stayed with the spacecraft and you could see the sequential flash off of those particles that was a result of our , our tracking light . OK , uh , this is the command module pilot . I've already mentioned in section 11.0 about the , uh , visibility of , uh , the lunar module through the , uh , optics . I got down here . Let's see . Anything else to add about Photography and television , and photography and the limb , uh , we'll just have to wait and see how it turned out . I took a lot of footage . Uh , Fact is we put it on , uh , not only the ascent mag , but we put it on the , uh , another mag . We have part of the mag pill . So , and that includes the Syey , uh , Right or wrong , we did have a , uh , a Hasselbo on board so we have a lot of hotbo photography , the rendezvous and some of the inner surface stuff in the process of . OK . Post docking , uh , like 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 latch made this time , right ? Every latch worked done . All wall docking latches worked , OK ? The , uh . So like , that sounds like it's something to do with the mass of the other vehicle involved here . The , uh , General comment I want to make about the , the post oping operations is that the , uh , Throughout the rendezvous , the , uh , The , uh , Both pilots in the lim kept their helmets on for , uh , dust , keep the dust off primarily . The commander took off his gloves , almost immediately after insertion and flew the entire rendezvous that way . You took yours off sometime later , didn't you ? I kept mine on , uh , After we've done a lot of transfer , I can't remember because I kept your gloves on too . You kept your gloves on . Oh , I , oh , OK , after insertion I did most of my , uh , pre-insertion work with the gloves on because I didn't want to take the time . I want to get that initial ag solution and I could , and I could get that . Fairly rapidly with the gloves , and I didn't take the gloves off until , uh , oh , maybe 10 or 15 minutes after insertion , but I kept the helmet on all the way through most of the transfer just to avoid breathing the dust because I've had the , uh , irritation , sinus irritation on the surface . And the commander kept the helmet on , uh , throughout the rendezvous and , Uh , Docking , I took my gloves off after insertion and left them off . Now , when we started , when we , we started getting prepared , as soon as we were hired dock , the commander . Took off his helmet , And as I look back at that , because of the dust debris in the LMS spacecraft . Uh , I'm sorry I did it . Uh , I could have left the helmet on and , uh , and I would have had a lot less , uh , not troublesome , but it was just , uh , eye and mouth type of irritation . You knew you were in a very heavily , uh , infiltrated atmosphere on the limb . Uh , because of the lunar dust , although it's , I don't know how much lunar dust previous flights had , but the , 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 , uh , we didn't see . Uh , So I had the commander had his helmets and gloves off off throughout the entire , uh , transfer . Basically the way we handled the transfer was the way we had planned the , uh , I think the , uh , Le pilot did most of the preparation of the gear in the uh . In the , uh , limb and a , and a commander stayed in a tunnel and , uh , Pass things on and , uh , the , uh , inventory was going on on the command module side and on the left side both . We , uh , vacuumed each other's suits the best we could and everything else that got supposedly transferred unbagged or uncovered . This is YMP and in spite of the CMP's comments to the contrary , I think we got things remarkably clean , and it wasn't an awful lot of dirt in it man like coming back . Oh , that's , that's true . I , I didn't want to leave that impression . OK , contrast , he may have thought it was , but , but , uh , I was surprised we were able to , uh , keep the . The level of , uh , pardon the expression , contamination of the command module down as well as that , that atmosphere that the commander was referring to in a limb after he took his helmet off , I could go halfway through the tunnel and stick my head up in the command module and it was a totally refreshed , unpolluted atmosphere up there and it never did get polluted . I think having a vacuum cleaner running in the limb had a lot to do with keeping the the flow in the . And filling out the air . Oh , did you ? Right . We never did vacuum in the command module because this wasn't necessary . It wasn't necessary to vacuum in the command module at all . And , uh , the suits were noticeably cleaned by the vacuum cleaner . Um-hum . You could tell you were pulling stuff off of them , although they were still , and every other subsequent time we handled them , we got our hands , but , uh , I think , uh , most of the tree dust was taken care of . We , uh , uh , we effectively stayed on a transfer list , uh , I say effectively throughout that transfer , however , some things got transferred , uh , uh , out of order , uh , and got temporarily stowed in the , uh , command module , but we effectively use the , uh , transfer list as a , uh , not as a , a cookbook , Follow a recipe type of thing , but as an inventory list , and , uh , we inventoried it several times from both ends and found out that , uh , we were satisfied we had everything transferred . And , uh , then press down with the lamp close out . Lum close op went nominal . Uh , we got back into the , uh , Into the limb or into the command module and uh the commander closed out the uh the the LMP closed out the limb . Uh , and for convenience , the commander , uh , effectively , uh , went back and closed out the limb hatch , put in a command module hatch , uh , because of the slow tunnel vent , or the long duration of tunnel vent , uh , the commander , uh , stayed in the tunnel , the LMP in the , his seat and the CMP in the left seat . Uh , we suited up and got prepared for our , uh , for our integrity check and as soon as the , as soon as the lung tunnel vent was complete and we were satisfied with the integrity of the hatch , we went into the , uh , uh , to the , uh , suit integrity checks . Yeah , this is a CMP . Let me make another comment on the tunnel vent time . I'll bet it must take , uh , and , I'm not sure if this is correct , but I bet at least , uh , 3 or 4 times longer than the simulator is for the tunnel vent , uh , move . And I think that's going to be applicable to Skylab because of their docking , uh , They're going to have to vent before the end , doc . Quite a , took quite a while . But tunnel closeout was easy . We had no , uh , no , uh , rogue and no probe , which were stowed , uh , Uh , in the , uh , lamb for , uh , Lamjet . Uh , going through the rest of these , uh , Mind triggers , uh , under lunar myogiosis through TEI . 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 lun jettison , you know , 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 it , uh , where we should have been maneuvering , and we ended up , uh , getting into P-41 after for the set burn . Uh , a little bit of light . But that's no problem either because we just turn the residuals and people were the one and and uh got a good supper . 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 the lamb . When we got back in the command 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 bagged before we brought it over , bagged and zipped , and we never did open anything , uh , once we got it zipped up , so the command module stayed , and I think that Su fan filter is probably going to be very , very clean , stayed exceptionally clean throughout the , uh , remainder of the flight . Let me , uh , in the bagging , the decontamination bags I made a special effort as for , uh . Request . Pre-launched to uh pull those zippers as tight as I could . And they should be pretty tight so . OK . Orbital navigation , high gain one , why don't you pick that up ? OK , I've already , uh , from except the TEI I have no , uh , no comments . I gain , that always worked good . Omnis and S band were good . Uh , photography , uh , When as advertised , we have a lot of targets of opportunity . Uh , Syey operations , uh , have been mentioned before . Let me just make one gross comment about the way we handle it as a three man crew at Syey operations , which after . Did you get that ? Did we ? Yeah . OK , it's covered . Uh it's covered . Oh , OK . I think I did say something , yeah you did . OK , the TEI updates . Normal . Section of star checks were good for . Got the commander's master alarm and every one of them all through the flight , which made me feel very good . Yeah , but you kept trying to get it . I made sure I got . I made , I made sure I got it on those last few . I wasn't going to change any mode of operation . I'll tell you that last one , Uh , where entry was the last one . I made sure I got it on TEI . 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 honor . The uh TEI at halfG or whatever we were pulling there uh was uh . Seemed like more than that . Quite noticeable . Yeah , it 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 relaxing back on the , on the couch . I guess we must have had the spacecraft pretty well stowed or tied down . Because , uh , as I briefed the CFP and LMP , and as I recall , those kind of burns back in Apollo 10 , lots of things start moving through the spacecraft and find their due , uh , on the , uh , On the after uh End of the spacecraft because of the G load and much to my surprise , uh , all we had was initial thud as we moved away from the station and we didn't have any gear coming from anywhere flying through the spacecraft . So we must have cleaned it up pretty well . I , I got a , uh , caught a white tagged wet wipe . A white tag wet one . But other than , than maybe one or two of those things , uh , and looking back , uh , 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 another point that reminds me , though , is that there is always water condensing on the ECU , uh , you know , the pipes and what have you back in there when you get back to clean the circuit return valve . And , uh , When we put our suits on for the EVA the next day , your , your suits were noticeably wet . Um-hum . And , uh , also when I pulled the PGA bag up , it was damp down underneath the PGA bag . So I think , uh , uh , as a nominal procedure , we should have , uh , Either after the burn , probably before the burn , make sure that we wiped out the water in the LAB somehow to do that . I wasn't really aware . Our suits were damp when we 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 . Which is an ECS . Yeah , an ECS , there's , there's always water down there in ECS , and I just assumed that's where all that came from , but , uh . It's funny , it was all over . It , it's , it's , it's not a puddle of water . Like you say , it was just damp . It was almost as if it was colder down in the LAB and water was condensing on all , all over the city . It wasn't as if they were in a puddle . Yeah . OK , I think that covers , uh , right on through , uh , TEI . Let's see , uh , yeah , the one thing I want to mention on TEI is that , uh , uh , again , the simulator is set up such that , uh , in the rolled dead band , it goes over to one side of the rolled dead band and just kind of stays there . And , uh , during the TEI burn , uh , it was bouncing back and forth from one side of the , the dead band turn over to the other side of the dead band . And when it's bouncing back and forth , the roll rate , Is up around , uh , Oh , Fortense , uh , 4/10 of a degree per second , arching back and forth across the road . OK , 14.0 Trans-Eth Coast and the thing that I just realized we've neglected to say anywhere about systems , uh , I'd like to mention chlorination at this point in time . I think without fail , did you ever talk about it ? No , I 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 leaks . Water or chlorine ? Well , or both . It's a combination of both . Chlorine and your chlorinating and , uh , and buffer or water when you withdrew the buffer sample . OK . But where it leaked was , appeared to me to leak within the ampule 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 , uh , dispenser fit into the , uh , needle or where the , uh , uh , needle adapter fit into the spacecraft . It was within the barrel chlorine dispenser itself , and , uh , we continually , chlorination was , uh , was a , uh , 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 wiped 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 . OK , look , let's see , uh , CMP , let me amplify that a little bit . In 2 cases . I'm almost positive that when you , Put the thing on in the bayonet fitting and crank it on there . It did not puncture the ampule itself . And the reason I can , I believe that's correct is that , uh , When you start to , to crack the , uh , Outside of the . Cassette . Down to to push the chlorine 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 , uh , an ampule on the thing . And if you take it , uh , just , uh , in two cases , took the bayonet fitting loose again and put it back on there , and , and in both cases , Then you try to squeeze the uh chlorine out of the ampula into the system and it would turn easier but it's still hard to to awfully hard to crank that awful hard to crank that thing down . But , uh , we did not , you know , 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 , uh , buffer samples , uh , So I guess we got the job done . It was just a little bit messy . And chlorine was evident and 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 flesh , a little skin when you did . Yeah . Transverse coast systems navigation , let's press on and see what we can say about that . Don't have lunch today . OK , uh , well , let me see how much transverse coast we're gonna do . Let's get , yeah , let's go through up to the CSM EBA . OK , transverse coat , the first thing I want to mention is passive thermal control . Was Uh , at what I would call unusual attitudes because of the UVN IR requirements . Now these unusual attitudes did two things . They , uh , they put us , uh , they required us to remaneuver the spacecraft several times and exit , enter and exit PTC several , several times , which in itself was not a problem . It was just , uh , additional , uh , coordination . Uh , coincidentally , most of these , uh , particular PTC attitudes were within . 30 , certainly 45 degrees of gimbalak most of the time . So we're looking at the red apple a 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 , the , uh , equilibrium heat load on a spacecraft . You could see it in , uh , in RCS , uh , quad temperatures were all right , but you could see it in helium package 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 for most of the way home ended up to be very dry . Uh , and the , uh , about the second day out on the way home , the , uh , the , uh , or the , uh , Main hatch Center hatch . Uh , got . Soaking wet to the point that , uh , I even 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 . I , I think this is all due to the , uh , PTC attitudes required for the Simba experiments on the way home . Oh , it was colder in the spacecraft too . Oh yes , it was colder in the spacecraft . Not as cold as the commander thought it was , but it was . 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 and the pin . I think we discussed that yesterday . We're on all your , uh , all your , uh , your ResMed changes , uh , your , uh , torquing , platform torquing , all those , uh , Went very well , I thought . It went great , uh , really well . The , uh , Uh , and , all the way back home , uh , it was just changing attitudes , changing attitudes , changing attitudes with the exception of the EVA day , which , uh , we'll cover here . Shortly . CSM EVA . OK , on EVA prep . I think the only anomaly we came across was the uh CMP's uh . Well , let's see , you're on EBA prep , but I really didn't have any . We didn't know anything at that point . On the , I was going to say on the CMP's , uh , compare . 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 went and stayed pretty much on the timeline . We started about a half hour in and stayed a half hour early . We , uh , we , we started out , we were a half hour early throughout the whole thing and we lost , That half hour and open the hatch just about it . You turn the TV on exactly on time , and I can't remember a small little . It was the carrier . Comp carrier change . And we lost that half hour during a comp carrier change on a tone . Uh , Ron , I'd like to add that , uh , 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 list at the long range stowage , as well as the post EVA stowage 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 point in time , yes . So our entry storage really started with the post EVA time frame , period , and I think that really helped us out in the long run . OK , I think , uh , we should mention how we got out of the suits and I think to me that was a pretty important , uh , way to get things done . And , The only change . The only change to the , to the , uh , Prep and or post was the order in which we doffed and donned suits because it was very evident that there were certain convenient ways because of the way the student suits were stowed and uh the way uh people fit into the , uh , checklist that we , uh , when we don the suits , the commander . You got down , you can't , you got in 1st . 1st , and I did and then run . Then the LNP and the , and the CMP got down last , and it worked out very fine that way , plus the CMP had less work to do in his suit , which also aided him in the long run . When we doffed , I went first . The LNP . Yeah , because I was stuffing first , OK , then you and 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 in the L shaped bag prior to . Putting the center , Couch back in , which was , uh , another good decision , I believe , uh , In helping us get the suit stove back in that L shape bag . Go ahead . OK , let's go on down to the cabin deep breaths . Uh , no problems . Normal , uh , deep breaths . 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 the hatch out of my out of my hand 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 , the . Dump valve was still open . And , uh , if I had not been hanging on to the hatch , I would have blown it all the way over . Well , Ron , 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 dump the lamp , and I'd still have to break that hatch loose and hold it open about 6 or 8 inches until things just vented , and then I could let go of the hatch and open it all the way . If I didn't , it would slam back closed . So we had an inward . Oh , yeah . Different types of . So it was basically the same thing . You've got to open it up and really let things get down to zero . OK , 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 went 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 , uh , coming out through the hatch . But I sure didn't see , I looked specifically for the scissors . I , I , uh , I didn't see any scissors go out that hatch . I hate to say it . None of them went by my watch . I , I didn't none of them went by me , Ron . I'd like to say that they went out the , uh , the hatch , but I sure didn't see them go . Sure you didn't say go by ? I didn't see , I caught the one thing that went , started to go by me and they put , put it in your pocket . You got to , OK , push straight . OK , the , uh , Once the , uh , all the particles and , and , uh , junk was out of the way , then you just push the hatch hatch open . We had disconnected the , uh , uh , counterbalance , uh , uh , With the beat to tool be there so that we locked the hatch in the open position , so I just shoved it open and it went beyond the center position and locked in the open position with no problem . Egress , uh , I had a tendency , I guess , uh , just like , uh , any other thing , it seems like you want to float up , and I had a tendency to float 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 hat in order to uh get past the uh . Get the OPS past the MDC and get on out . TV and deck insulation , uh , work fine . I can hang on with the , uh , right hand on the , uh , hatch , uh , the great big , uh , D handle on the hatch . And , uh , with the TV pole in my left hand , and it worked out real fine to just stick it in there and then line it up with the mark and uh make sure it was uh . Uh , locked in or clamped in . And then , uh , climbed on up the pole to , uh , turn the TV on or turn the , uh , dock on . And it was , you couldn't see the light . I couldn't see the light on the thing , but you could feel the camera running once you turn it on . You could just touch it and you could feel it , feel it vibrating a little bit . The , uh , lunar sound or cassette uh retrieval , um . I think , uh , they should be on the on board , uh , or on the air-ground tapes . As I was describing , uh , most everything that was going on , there was no problem . The pan camera cassettes were next . No problem on the , uh , pan camera cassettes and , and the pan camera , it's obviously a bigger mass , and it's , it's , uh , quite apparent when you try to maneuver , move , move that big mass around that it is heavier and it weighs more than the , the other things . It's easy 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 under control . Mapping camera cassette . Had the same , uh , problem I had in the , uh , In the same by , uh , C 2 S2 , getting the , uh , The , uh , Thermal cover off . It's stuck underneath the mapping camera laser altimeter . Uh , door . But , uh , there was no real problem , you know , I had the feet and the shoes just give it a big jerk and then it finally came off . Symba inspection , uh , that's all covered in the . On board the , I mean the air to ground tapes . TV and dock removal , uh , again , was real simple . You 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 , uh , TV around and , uh , point it toward the , the moon because I didn't have to worry about shining it into the sun . When I tried to again hang on with one hand and , 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 tried to be a little more accurate on the thing and when I did that , then I lost , Kind of effectively really lost control of the , Uh , my body position because I was trying to , to , uh , I think , maneuver the camera . And I just . You need both hands to maintain your body control again , so rather than try to , Flashed the camera through the center or something like that . I gave up on trying to point the camera out there . Calm during EVA , uh , was loud and clear for me , uh , throughout the , uh , Throughout the EVA there was a lot of background noise , the hissing , uh , of the airflow , and I'm sure that was probably coming over the , uh , the box circuit circuit . But , uh , I don't think anyone had , it didn't appear to me that anyone had any trouble on the ground . I think one of the big advantage there around the LMP that one thing we did because it was bothering you at first week , I turned your sensitivity down about two notches . And apparently that really improved the calm for is the impression I had . Yeah , I , I had that impression from the ground . I don't know if it , if it made any difference or not , but I got the impression that it did help . Calm into the cabin was excellent . I never had any trouble understanding you . I had the hissing in the background , but we , uh . Yeah . Yeah , I thought it sounded much better than I remembered other flights sounding . Um-hum . On the air to ground . Well , our CMP made more noise than it . I guess I used the wrong word there . It was clear . Clearer . Uh , ingress , uh , seemed to me like it was easier than the egress . Yeah , for some reason , uh , hatch closing was , uh , harder than I anticipated . And I guess maybe this is the , uh , the same reason is that I must have been exhausting into the cabin all the time and just that latch the hatch would come close to within about 1 inch of closing on the outer edge , and then it took an effort to pull the hatch closed so that you could activate the , uh , the , the latching handle . So that you could over get the uh the latches over the center . Of course , once you got the first stroke on the latching handle and got , got the , uh , hat , uh , the latches over center , then it's , uh , really easy , just a couple more cranks on the , uh , On a hatch , uh , cousin . Kevin Repress , uh , was nominal . Let me , uh , add my comments here , this LNP , uh , all I did was work in the hatch area , and , uh , I want to emphasize , I think what everybody has always said is that , That you do your best work when you take things slow and easy and just let yourself uh move yourself in small increments to where you wanna go , you can turn and dip and raise yourself up , and I think it's also useful , uh , for any cabin hatch or . Our port operations , uh , to have somebody else available to , uh , push you out on your tether as far as you wanna go and pull you in , it just eases the operation . Gene was doing this occasionally for me . But , uh With the kind with the struts 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 was , had this 90 degree disorientation feeling for a few seconds until I . Got the perspective of the cabin again and said , OK , that's right , and I get back in and then I'd go back outside and I come back in again and then once again it seemed as if the cabin had rotated 90 degrees to my perspective and uh . It's just something that's no problem , it's just a , a change of perspective for some reason that I , I , I experienced several times . Uh , Uh , I guess the biggest problem working in that angle for me , sun angle , or attitude was , uh , I , uh , I had the sun full face . You , you had the sun in your eyes most of the time . And , uh , so it made it hard to look in detail and see what you were doing . It , you were a clear image . You were there and I could see every major operation doing it , but if I had to specifically see details , it was , uh . Oh , I don't know , 11 point I wanted to make , uh , uh , also , was it , I had no awareness whatsoever that I had an umbilical on my back . There was , I , 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 that the umbilical ever get . Tangle around , uh , my feet . The umbilical was , uh , was easy to tend , and , uh , I frankly don't remember a single time when I had to , Clear it . There may have been one . So I have a vague impression that one time I asked you to , to hold up or , or maybe I didn't say anything . I just moved it away from a handhold or something , but the umbilical was , uh , was very , uh , it didn't tend to snake around , and it was , uh , you seemed to have everything you needed on it . Um-hum . It worked out real good . problem at all . I didn't even know it was there . I guess , that's the point I was making is , is it really , uh , being tied to the umbilical does not restrict your movement or , uh , or give you a feeling that it's , it's , it is restricting your movement at all . Su doffing and storage , I think we've already discussed that . Uh , this is continuing on the EVA , uh , part of it , but , uh , I don't know , this is just a different section here , suit doffing and stowage . We've already mentioned the doping storage . Uh , the light flash , uh , phenomena . We Three of us were blindfolded for an hour and uh never saw a light flash . That was the second round , the second round on the way back and the transverse . Eating , resting , exercise , and comfort . Let , let me add to the light flashes LP that the next , uh , that evening , I guess it was , I did see them again , falling asleep . So , I did too , so there was just that period apparently during the actual experiment that that for some reason they weren't because . I think we've discussed the eating , uh , resting , exercise , and comfort already . cabin atmosphere . Uh , the one thing , uh , That I don't think we've , we've ever mentioned yet , and I think should be noted is that we , Uh , never really utilized the waste storage vent . To get rid of any odors out of that waste storage compartment . And if you , if you kind of drifted over in that area , it was always apparent you were in that area if you got real close to what I thought it was . I never noticed it . I never noticed it . I think generally I guess maybe I did when you opened the door , that's when you really noticed it . The cabin , generally , Uh , Turned over the atmosphere , Uh , in pretty good style . Uh , it got saturated sometimes with , uh , with gas , and it took , uh , Uh , a few minutes , but once the source of that gas was , uh , Uh , was plugged up . The , uh , the cabin did a good job of recirculating , cleaning out the I think it did . I think . Real good . Flight plan updates were super . The flight plan was excellent , and they were held to a minimum , and we really didn't change any part of the entire flight except a few dates and times and , uh , what have you here and attitudes , attitudes , uh , but other than that , it was really at a minimum . I see that . Entry preparations really began , uh , after EVA and uh continued all through the next day . And , uh , we had very little final stowage to do on entry morning . Just those things that we had to leave unstowed until we got , uh , got out of our sleep restraints . So we basically just had to tie the big bags down on on a 1 and 2 and 7 and 8 . And , uh , final entry preparations went by the , by the checklist , and , uh , if anything , we stayed about 5 minutes ahead , Uh , throughout the entire checklist , including , uh , separation and activation of the , uh , Uh , command module RCS and , uh , picked that 5 minutes up , of course , right at , uh , 05G which came on time . The , Communications , I thought , uh , were very good through that period of time . We were through Arria the last couple of minutes prior to RRT . And I understand now the ground heard everything we said right on through blackout , into blackout . And then I , and as soon as we came out of blackout , they still had a riot , and they could read us . Uh , and we could have read them , but they never transmitted it . Oh , that was it , OK . Yeah . I'm running out of tape here , but uh , No , I can't think of anything else . Well , on the corridor checks , sir , we got , uh , Horizon and Moonset . Right . Yeah . Without any problem , well , with , with problem of looking , but , uh . But we had them all , and they all were within seconds of the actual time . They were all within seconds , and , you know , in the , in the CMS , I'd always looked for the 2G when the corridor light would go out though . I didn't even notice it . In the blood . So I must have been , I was either watching something else , uh , I must have been checking the , the EMS or ,
