CC: Roger. And we've a camm check coming up with the LM and the - the time - the earliest time at which you've got a Contact with them is 128:14:14.
CMP: Understand; 14:14.
CC: Roger. And Bob is on board now. So I'11 be signing off and seeing you in the morning.
CMP: Okay, Karl. Go home and have a nice dinner and I'11 talk to you in the morning.
CC: And, Al, it's your computer.
CMP: All righty. Good morning.
CC: Evening.
CMP: Okay, Bob. I'm just coming over - over Picard at the present time, and wanted to make a comment that it looks like there are - there are several ring structures inside the - the basin itself. They're all concentric, and I don't see a great deal of relief on those that look like they're in the bottom of the basin. But looking at the - looking at the - scarps around the - the - the outer ring, Picard looks - looks like it's Just - almost a caldera-type. They look almost like - fault plains along - along the outside. And I can see in the - in the - in the outer wall very distinct layering. For instance - the top - right at - right at the top is a very thin dark layer, and that. runs all the way around. And there's a light-colored layer. And then there are alternating dark and light layers all in about the' same - distance from the top of the crater - all the way around.
CC: Roger; copy, Al. That sounds like a pretty complete description.
CMP: And, as a matter of fact, Bob, I can make that same observation about Peirce - especially Peirce Alpha. This - I - I notice the same kind of layering and the same kind of horizontal lineaments in the - in the wall of the crater.
CC: Beautiful. The king'11 be proud of you.
CMP: Okay, Bob. I'm up over Proclus now and that's one of the visual targets. And a couple of comments about Proclus, which weren't too obvious from the pictures we've seen before. The - the edge or the segment of the crater, which is in the excluded zone of the ray pattern - which - the ray pattern, by the way, is very distinct even from directly - directly overhead. That little segment of the crater wall seems to be - discontinuous with the - with the rest of the crater. In other words - the - the crater, if you - if you made a circular .... ring - and you showed that as the crater, then - then this little chunk in that - in that quarter where the excluded zone is, lies outside of what you would describe as a circle for the crater itself. It's - it's like a little dimple in the crater itself. And I can't see anything in partic- ular there close to the rim that would account for any Shadowing - any physical shadowing of the ray pattern. But I - I can see a diagonal fault zone that runs down into that little dimple that I just described a minute ago, and runs into that dimple from the east side. I couldn't pick one out on the west side, but it's very distinct on the east side.
CMP: And, in addition to that, I didn't see - I didn't see a great deal of difference in the - in the terrain or in the structure of the terrain across the excluded zone.
CMP: HouSton, Endeavour.
CC: Go ahead. _.
CMP: Okay. I'm looking right down on Littrow now, and a very interesting thing. I see the whole area around Littrow, particularly - part$cularly in the area of Littrow where we've noticed the darker deposits, there are a whole series of small, almost irregular shaped cones, and they have a very distinct dark mantling just around - tho - those cones. It looks like a whole field of small cinder cones down there. And they look - Well, I say - I say cinder cones, because they're somewhat irregular in shape. They're not all - they're not all round - they're positive features - and they have a very dark halo, which is mostly symmetric, but not always, around them individually.
CC: Beautiful, Al.
CC: And, Al, you might want to be reminded at this point, we're getting toward the VHF. --
CMP: Thanks, Bob. Just going to give them a call. Hello, Falcon; this is Endeavour.
CDR-LM: Hello there, Falcon. How you doing?
CMP: Hey, going real fine, Dave. We - we're just doing the photography bit and doing a few visual obser- vations. And I've taken a look at you a couple of times down there. How's it going there?
CMP: Yes, I am. The rille is Just coming into sight now.
CMP: Well, I looked for him before, but couldn't see him, while I Eot the monocular.
CMP: Very good, very good. I understand it was a very successful EVA.
CMP: Yes, it appears that they're getting some pretty good stuff now. 83/9 Tape
CMP: Sure is. i -
UNKNOWN: I'11 bet it is. Okay.
CMP: Are you finished for the day's activities now?
CMP: Very good. Get a good night's sleep.
CMP: Oh, I'm living the life of Riley up here now.
CMP: Very comfortably.
CMP: I won't, Jim; I'11 save room for you.
CMP: Save you some food? I'm not sure there'11 be any left. I have a well-stocked pantry here.
CMP: Well, Davy, I think I got you on the monocular.
CMP: No, I can't see any tracks, Jim, but I can see discoloration, rather circular, that looks like it's around the LM.
CMP: Is it over east of you?
CMP: No, I don't have it.
CMP: Yes, all I've got's the monocular.
CMP: Okay; get to work, and I'11 talk to you tomorrow.
CMP: Houston, Endeavour. MAPPING CAMERA is going to EXTEND now.
CC: And, Endeavour. We'd like AUTO and HIGH GAIN, please.
CMP: Roger, Houston; going AUTO.
CMP: Houston, the MAPPING CAMERA talkback is gray.
CC: Roger; copy. Thank you.
CC: And, Al. We have a mapping camera photo pad for you, when you're ready to copy.
CMP: Roger, Bob. Go ahead.
CC: Okay. T-start, 129:26:52; T-stop, 130:26:30. And it says note: At T-start, MAP CAMERA IMAGE MOTION, INCREASE; talkback barber pole, plus 4. And at 130:08, MAPPING CAMERA IMAGE MOTION, INCREASE, talkback barber pole. Over. camera
CMP: Roger; understand. Mapping photo pad. T-start, 129:26:52; T-stop, 130:26:30; and at T-start you want the image motion increased to barber pole, plus 4; and at 130:08, you want image motion increased to barber pole.
CC: Roger. APOLLO 15 AIR-TO-GROUND VOICE TRANSCRIPTION
CC: Go ahead, Hadley Base; this is Houston.
CDR-LM: Okay, we're all settled down now with some good beefsteak, and all cleaned up and ready to talk.
CC: Sounds very good, Dave. We've got a list of questions here; some fairly general geology ques- tions at the last, and, depending upon your an- swers, we'11 build a good part of EVA-2 on it. Stand by a second; I've lost a lockon. Okay, we'd like to begin, though, with some fairly simple mechanical questions that'11 require a Ja, nein answer to most of them, I think. And they involve ALSEP and - Rover. And I'11 Just - start off at the top of the list here. Dave, which ALSEP photos did you get out of the way?
CDR-LM: I got them all but the heat flow, Joe.
CC: Roger. Copy all but the heat flow. And, Jim, when the LSM sunshieldwas deployed, do you think the instrument stayed more or less steady? Or do you think it may have moved a little bit?
LMP-LM: It might have moved a little, Joe.
CC: Dave, say again. I didn't copy that.
LMP-LM: Is there a problem with the - Hey, Joe, this is Jim. It - it might very well have moved. In other words, it's not level any longer?
CC: Negative, Jim. We don't necessarily know that. As far as we know, the data looks pretty as a picture. We Just want your own feel for it.
CC: In other words, we have no reason to believe it moved. We Just wanted to get some words from you on that.
LMP-LM: I didn't notice any movement when I deployed the sunscreen, Joe.
CC: Okay, fine. When you took the double core, did you notice any soil falling out of the core tubes while you put the caps on?
CDR-LM: Yes, there was a slight amount of loss from the lower and a little bit from the upper, but very little.
CC: Okay, that sounds good. And regarding the question about the Rover track, Jim, you told us they were one-half inch deep or less, and we're wondering if that was a typical number over the - the course of the entire traverse, as far as you could notice?
LMP-LM: Well, that was my impression. Half an inch in - in general, but Dave probably has another comment.
CDR: No, Joe, I'd say no more than a half an inch. It seems to ride very lightly; I think the - the bearing on the surface is - is very light, and the wire wheels seem to work very well. They've got good traction, and even though the rear end did break away several times, it was primarily because of the locked-up front wheels. And I was very pleased with the operation. I think the thing performs better than we'd expected.
CC: Okay, Dave, thank you. Now a series of questions about the heat flow. We want you first to - to describe the drilling characteristics, and do you think you're drilling into a layer of rock? Over.
CDR-LM: I'd say yes, Joe. The drilling characteristics are - the gradually increasing requirement for force to get it in are more so than any force I experienced in the ones in training, even though they had the packed soil. One time we did have some that was packed so tightly I couldn't even get it in, but that was because of the weak battery on the training unit at the time. The drilling, - it requires more and more force the deeper you get. And, you could probably see the TV there at the end on the second one, I had the second probe about half way in, and I was putting almost my entire weight. Even though it's 1/6th, there was quite a bit of force behind that drill, much more than I've ever experienced in any training. And I - I had the impression that, yes, we're drilling through rock. Tape
CC: Roger, Dave. We hear you on that. A similar question, was the drill torque high while you were drilling?
CDR-LM: Well, high is a relative term. I had to maintain quite a bit of pressure on it to keep from being turned, but I - I tried in the 1/6 g airplane several times to see if it was too high that - or that I could- if I couldn't hold it, and I could always hold it. And I can hold it here, even though the - the torque was fairly high.
CC: Okay, Dave, that's a clear description. We know that the stem is loose in the hole as far as the rotational motion goes. We're wondering if it's loose in the up and down direction. Do you think you could pull it out?
CDR-LM: I don't know, Joe. I - I don't really know.
CC: Okay, Dave, copy that. Is the drill thermal shroud off the drill unit?
CDR-LM: Yes. You mean the small all_m_num colored shroud that goes over the battery?
CDR-LM: Yes, that's off.
CC: Okay, and were the Boyd bolt guide cups remo_led from the heat flow experiment?
CDR-LM: Gee, I guess I have to think about what you mean. All the Boyd bolts are off of the - the box, as far as I know.
CC: Okay, Dave. Our question concerns the covers for cups down here.
CDR-LM: Do you mean are they off now or were they off when we started?
CC: Dave, we mean are they off now. Did they fall away from the unit when you picked the unit up. It's of - of relative unimportance, really, but it would be an interesting data point.
CDR-LM: I didn't pay much attention, Joe, but I think all the Boyd bolts came off the heat flow, finally, I think.
CC: Okay, Dave. Thank you. Jim, was the central station Sun compass on the orange mark when you last saw it?
LMP-LM: Yes, it was, Joe.
CC: Okay, and I'm sorry I skipped over a question here. Dave, where is the drill vise and the drill treadle right now, as you remember.
CDR-LM: The drill vise is next to the second probe, which is the western probe, and the treadle is at the point at which we parked the Rover.
CC: Okay, that agrees with - -
CDR-LM: ....
CC: - - our guess on that. Jim, once again back to the central station. How accurately was the bubble level when you saw it?
LMP-LM: Oh, it was within - oh, 1/8th to one-quarter of the center.
CC: Okay, that sounds good to us. Could you tell us whether the north-facing side of the central station can see any portion of the RTG?
LMP-LM: No, it definitely cannot. Because the RTG is perhaps a - a little south of and east, as far as the central station's concerned.
CC: Roger, we copy that. And, Dave, could you call out to us the problem with your yo-yo. Do you - and do you think it can be fixed?
CDR-LM: No, we looked at it when we got back in, Joe. The string broke at its attach point on the inside of the yo-yo.
CC: Okay, Dave and Jim, you might want to consider switching out the yo-yos. Jim, you may want to pass yours over to Dave for the next EVA.
LMP-LM: We've already done that, Joe.
CC: You're always one step ahead of me. Some quick questions about the Rover now. Could you confirm that battery 2 amp-voltmeter always reads zero, please.
LMP-LM: I guess I can't answer that, Joe. I could never see the amperage on - on 2 when we were driving.
CDR-LM: Yes, my answer, Joe, would be yes. I never saw a motion of that needle.
CC: Okay, that's good - plenty good enough for us. As you know, we think that you've got two good batteries, but possibly a failed meter there. And the Rover power consumption looks like it's right on the money, and we've got a lot of gas for the next EVA. The amp-hour meter data which we have does have a couple of erratic points in it. we're wondering if you noticed any meter-movement anomalies.
LMP-LM: This is Jim. I didn't notice any meter motion or anomalies, Joe.
CC: Okay, Jim, thank you. And we're ass_m_ng that the Rover is now parked facing north. Is that correct?
CC: I could have guessed as much. And a question about the suspension, which sounds kind of exciting. Did you ever notice it hitting bottom?
CDR-LM: Yes, we hit bottom a couple of times when we hit a rock, and it seemed to respond fairly well. I mean you could Just feel that it had bottomed out. problem, Joe. I'm sure you're right about that because I noticed in backing up a couple of times that the front wheels did drive.
CC: Okay, interesting comment, Dave. Thank you. Now we're getting on to the toughies here, and coming up to a very interesting one. We'd like to know what your best estimation of the LMs position is. Over.
CDR-LM: Stand by.
CC: And, Dave and Jim, let me give you some background on that. We've got several points that are in a very tight cluster around the first location we gave you. We think, however, because of boot- strapping a location from Elbow Crater backwards using the Rover navigation system, we think that you may be mistaking Last Crater for Index crater. And I want you to consider this as you look at your map and think about your present position. Over.
CDR-LM: My!
CDR-LM: Joe, you've stimulated an interesting discussion. Give us a couple of more minutes.
CC: We thought we might, Dave.
CC: And - Dave and Jim, as you well know, this question is pretty much academic because we're - we're doin_ great guns, no matter where your exact location is, and it's something we'11 construct later. But we' re interested nonetheless.
CDR-LM: Okay, Joe. How about 733 Bravo Sierra 4? And I guess that's because we are on the northeast side of a - double crater.
CC: Voila. We understand.
CDR-LM: Sure nice that Rover will make 12, 13 clicks, isn't it?
CC: That sure is, Richard's studying the maps here momentarily. In the meantime, could you give us - Just a rough guess, a quick rundown as to where the samples at station i were taken with respect to the rim of Elbow, and we're interested in distance and direction from the rim. Just a rough guess.
CDR-LM: Okay, Joe, 709, Bravo Echo 5, and we moved out about 200 feet to the east of that point in picking up the C radial sample.
CC: Okay, Dave, copied that loud and clear. And, by the way, Rover nay system gave us exactly the same coordinates as you Just called down for your LM location. Interesting coincidence, or perhaps not a coincidence. Moving on to the next ques- tion. Near Elbow Crater, Dave, you mentioned that your footprints exposed white soil. We wonder if this was a common occurrence. Did you observe similar white soil in footprints elsewhere? Over.
CDR-LM: Joe, I sort of kicked through a rim of a small, 1-meter subdued crater; and, as I did that, i kicked up the white soil. And so I kicked a couple of more times and it spread out; and whether I was - breaking up a very viable rock or not, I don't know. But there was a couple of kickfuls of dirt that was white, and as we came back past it on the - on the return trip to the LM, why, I pointed it out to Jim and he saw it too. And I'm not sure whether that was Just at that one small crater, which was an old crater, or whether that was typical of that particular area. We Just didn't have time to look at it.
CC: Roger, Dave. Copy that. And coming back to station l, Elbow Crater, could you give us a quick rundown on the changes in rock distribution around Elbow Crater and, if possible, maybe even the changes in rock types there. Over.
CDR-LM: Stand by 1.
LMP-LM: Joe, our clocks were running pretty fast when we were there, and I guess - we didn't get a chance to look at the distribution very well. As I remember it, there - there were more blocks - not really blocks, but large fragments, on the order of 6 inches to a foot, more on the southern rim, although it wasn't really heavily concentrated; I'd say 10 percent of the surface at most. There was more on the southern rim than on the northern rim. And the ones we sampled all looked pretty much the same. As I remember, the radial sample didn't show a great difference in rock type. Although, as you know, we Just didn't - a chance to do much - looking and thinking then.
CC: Roger, Dave. We copy that, and answers that question very well. But, once again, regarding Elbow Crater, Jim, you called out to us a bench around the east side of Elbow and you were looking down into Elbow from higher up on the front. We wonder if you could compare that bench with breaks in the slope of the rille wall. Over.
LMP-LM: Joe, when I commented on bench there, I would estimate two or three different levels that are very - were very subdued possible benches in Elbow, and I did not see any immediate relation between those subdued benches in Elbow and the - the rille.
CC: Okay, Jim, copy that. That sounds very reasonable. We'd like to move on down towards station 2 now, and - and have a series of questions about sta- tion 2. The first one, being, what rock samples did you get from Station 2, and we're more inter- ested in the samples that did not come from the large boulder, but rather what other samples did you get there? Over.
CDR-LM: Okay, stand by.
LMP-LM: Okay, Joe, our - our sum total at Station 2 was two chips off the large rock, soil from the fillet, soil adjacent about a couple of feet away from the rock, soil from beneath the rock, and the double core, and the comprehensive.
CC: Okay, Dave, you called it right on from memory. That's exactly the score sheet we had. Stand by a second. Let me - let me read over this second question. Okay - -
CDR-LM: Okay, Joe ....
CC: - - regarding the boulder, do you think possibly that the black part of the boulder might be a big clast in a coarse breccia? Over.
UNKNOWN: No, I'm not sure, Joe. The breccia that was in there was glass covered, and there was an exposure after I took a chip out of it that was a breccia not unlike 14. As a matter of fact, I'd say it was almost typical of 14s, but maybe only second or third order. There definitely was a - a linear - I call it a contact. Whether it might have been a very large clast inside a very large rock, there's no telling. But there was a definite line there which differentiated two types of rock Within that big boulder, and I - I really wouldn't want to guess whether that was a large clast or not.
CC: Okay, Dave, sounds good. Could you tell us where the samples which came off the boulder were taken in relation to this contact that you called out on the boulder? In other words, where did the chips come loose from? Over.
CDR-LM: Okay; if you consider the boulder being divided in fifths, 1/Sth of it was a different type, apparently, by this sort of topographic contact. We took one chip from that side and one chip from a corner on the other side.
CC: We copy that; thank you. We'd llke for you to sum- marize the relationship of mare and Apennine Front in the Elbow-St. George area. And, we're looking for any evidence whatever of a contact, an albedo change, or a change in coarse-frag abundance. Over.
CDR-LM: Joe, we looked, and we discussed it before we went out, and we've discussed it since we came back, and we - we honestly didn't see anything.
CC: Roger, Dave; and you discussed it, then, about the same way during the traverse. So it sounds very consistent to us. Do you think that you can drive to either Spur or to Window Crater?
CDR-LM: Let us take a look here, quick.
CDR-LM: Well, there are a number of craters down there in the area of Spur and Window, and those are the only craters up on the Apennine Front. And there are several the same size as Spur and Window, which I think were not evident on the photography because of the - the albedo and the Sun. I think we could get to some of those craters, yes. I - I'm not sure it would be Spur or Window, but there are some craters up on the side of the Front I'm fairly sure _ we could get to.
CC: Roger, Dave. Copy that. And that is exactly the answer we were after; not necessarily those partic- ular craters, but craters similar to them; and we understan_ exactly what you're saying. We'd like to ask, was the abundance of white and light-gray rocks described in the vicinity of - of Falcon the same seen along the entire route to St. George, or did this abundance of white and light-gray rocks seem to vary? Over.
CDR-LM: Joe, I think we have a great variety of - of frag- ments out here. I - I wouldn't want to pin down any particular type in any area until we had more time to look. We've got a couple of surprises for you. We have one fragment on the order of 6 inches which is a - a fairly well rounded, highly vesicul_, basalt with vesicles on the order of B millimeters all over it, apparently quite old and rounded, and it's a - a brown - a brownish gray. We also have a - a large piece of glass, Just sheer glass, appar- ently, which is about a foot long and about 6 inches wide and very rough-textured surface; and that was the one that was right out the front window here that I described yesterday. And the basalt we picked up halfway back when I had to change my seatbelt; I saw it on the ground, and I just couldn't resist it. And it's unlike anything you've seen from the Moon before as is the large piece of glass. And I think those are indicators, to me, that we have a great variety of samples out there, and we really need to do some good careful looking as we head down towards the Front.
CC: Roger, Dave. Read you loud and clear on that, and that really brings us to our last question. We're in the process of starting to plan your traverse tomorrow. It's going to be a good one. We have no equipment problems that we're looking at right now and we'd like to ask you if there're any particular inputs you would like to make into the planning team regarding tomorrow's traverse. Over.
CDR-LM: Okay, let us talk it over a minute, please.
CDR-LM: Joe, we've talked it over, and we think the best thing to do is to stick exactly with the plan we have now. I think we understand what we're looking for, and even though we didn't find any - some of the things we were looking for today, that doesn't mean that we won't find them as we head down to Front Crater. And I - I guess about the only input we'd have would be that, if we can make as good a time on the Rover tomorrow aS we did today, perhaps we'd have more time to sample a - a variety of stations along the Front and on the way back. But, in general, I think we'd do better if we stuck with our preflight - preflight plan.
CC: Right on, Dave. We copy that, and I think we're going that direction. Sounds good. We got a - a couple more general questions and then a - a comment about the 16-millimeter camera, and after that we're going to be closing up shop down here. One more geology question. Do you have any feel for whether the frags around the small fresh craters that you've called out to us are, in general, pieces of the projectile or do you think they're eJecta frags? Over.
CDR-LM: Well, Joe, I - we're pretty sure they're projectile frags, and that's when we really need to stop and sample.
CC: Agreed, Dave. We think the same thing here. A quick comment on your 16-millimeter film. We think that that camera, the DAC, is still in good shape. That MAG Charlie was a bad magazine, and we think you can help us out on the other magazines left tomorrow by advancing the film with your finger Just to make sure it's moving freely in the maga- zine before you clip it onto the camera itself.
CDR-LM: That's a grand analysis, Joe. We're ...
CC: And that's something you can do while you're packing the ETB. Can do it tonight. Over.
CDR-LM: Roger, Joe. That's - that's a good analysis. We took MAG Charlie and tried to run it with our fin- gers and it won't run. It's absolutely Jammed right in the beginning. And we'11 run the others through tonight to make sure they'11 work.
CC: Sounds terrific. And, Dave and Jim, we'11 be standing by for a crew status report. No hurry on that; and, as I say, we're going to close up shop down here. We've got more data, really, than we know what to do with. But we'11 work hard on it and be back with you in the morning. I do have lift-off time pad to send to you, Jim, when you're ready to copy.
CDR: Okay, he's got his pencil out. Go ahead.
CC: Roger. Lift-off times: T-28, 132:17:54; T-29, 134:16:02; T-BO, 136:14:10; T-31, 138:12:19. Over.
LMP-LM: Okay, Joe, beginning on 28: 132:17:54, 134:16:02, 136:14:10, and 138:12:lg.
CC: Readback correct. Jim. You've been doing good work all day.
LMP-LM: Well, we're trying.
CC: Roger. And, Dave and Jim, one last comment which we're - we're pretty sure you're aware of. We - we think we 're looking at an EVA tomorrow that '11 run about 6 and a half hours, about the same thing we did today. And we do have a few miscellaneous items to clean up, either - most likely at the end of the traverse, so it's liable to be a little shorter distancewise, but otherwise, other than that, it'11 be more or less unchanged. Over.
CDR-LM: Okay, very good, Joe. By the way, did you notic e that I had a higher 02 usage all the way through, and is that why we're looking at 6 and a half instead of 7 hours?
CC: That's correct, Dave. We've got very good data points on you. It's a steady curve, and the 02 -_ rate is Just a little bit higher than we predicted and from the looks of it, you've really been doing some work up there.
CDR: Well, do you have any idea why there's a rate? Perhaps maybe a - a zipper could be lubricated or- or something like that?
CC: Dave, this - this is a metabolic curve, plain and simple. It's not a leak rate at all.
CDR-LM: Okay, well, I'11 breath a little less tomorrow.
CC: We don't recommend that, although the Surgeon's working on it right now. The numbers though, actually that we're coming up with, Dave, is about - The two numbers are llS0 Btu's per hour, working, and about 700 Btu's riding. Over.
CDR-LM: Okay; that's a little higher on the riding than I think we expected, but it's sort of a - a sporty Job to drive this thing to make sure we don't run into the craters; and if you can get that front steering figured out, it'11 sure help.
CC: Get 6 and a half hours like you did today, guys. Nobody's going to complain.
CC: Dave and Jim, I'm going to sign off now, and I'm getting excited about tomorrow's traverse already. And Bob's coming on. Over.
LMP-LM: , Okay, Joe. You did a superfine Job today, and we sure appreciate you keeping track of us and keep us going in a straight - straight line. We'11 be looking forward to seeing you tomorrow.
CC: Yes, sir, wouldn't miss it for the world.
CC: And, Falcon, we'd like biomed right, please.
CDR-LM: Okay, biomed right. There's nothing there right now, but we'11 give it to you. u_derstand.
CC: Roger. Yes. We
CC: And, Hadley, this is Houston. Over.
CC: Roger. You got 5 minutes before you have to turn the lights out, and we'd like SUIT GAS DIVERTER to CABIN, CABIN GAS RETURN to AUTO. And the doctors would like a crew status report, can you believe.
CDR-LM: Okay; we'11 come back to you Just for that later.
CC: And, Endeavour, Houston. We can terminate BAT B charge at this time, please.
CMP: Roger, Houston. Will do.
CC: And, Endeavour; Houston. We're 4 minutes to LOS. A couple of c_mments before you go around the corner. First, the surgeon thinks you may have loosened part of your EKG harness while you were exercising. Like you to check that at your con- venience. Second, we have a new gsmma ray retract time on the back side of 129:20. Over.
CMP: Roger, Houston. Understand going around the back side. I'11 check on that biomed harness. I may have loosened it exercising. And understand you want the gRmma ray boom retracted at 129:20.
CC: Roger. We won't be able to see it to keep track of the times, remember, Al. And, also I guess the mass spec people would appreciate any more comments you can think of. Next time you take a look at those particles at sunrise. Over.
CMP: Okay, Bob. Will do.
CMP: Houston, Endeavour. One last comment.
CMP: Okay. When I took the battery B off charge I checked the systems test meter for battery pres- sure - battery compartment pressure - and it was - the systems test meter read 1.4, which is - looks like it's getting pretty close. Is that test - test meter still working all right?
CC: Roger. Stand by. We're looking at that.
CC: Okay. That's - they say that's nominal. That looks good.
CC: And, Al, if you read, we'd like to have your DSE configured.
CC: Endeavour, Houston. We'd like REACQ and NARROW, if you can. And we have good biomed data.
CC: Loud and clear now.
CMP: Okay. Reading you loud and clear also.
CC: Endeavour, we have a small series of updates here, if you're ready to copy.
CMP: Okay, Houston; Endeavour. Go ahead with your updates.
CC: Okay. First one is a change to your erasable load printed in the G and C checklist. This change has already been made in the computer. It's on page 9-4 and I'11 wait for you on that one.
CMP: Okay, Bob. I'm here.
CC: Okay. And on coll_mU Delta, line 05, we will change that number from "01571" to "01605." Over.
CMP: Understand. That's coll_mU Delta and octal ID 05, change to "01605."
CC: That's verified. And all the next updates here are in the Flight Plan.
CC: Okay. At - These are changes to the bistatic radar at 130:52, "POO at PITCH 177 degrees." And we're deleting the "POO at PITCH 171," at 130:54 there. _-_
CMP: Okay. And what time do you want that? At 130:527
CC: And at 131 -
CC: - at 131:10, we will change the VERB 49 maneuver to bistatic attitude, from "067, 171, 00" to "067, 177, 00." So the PITCH changes to 177. Over.
CMP: Roger. Understand. Change the PITCH to 177.
CC: Okay. At 131:32, we're going to change the NOUN 78 values. We're going to change R 2 to "plus 067.00." That's R2.
CMP: Okay. Understand. Change R2 from "047.50" to "067.00."
CC: Roger. And at 131:39, the "start auto pitch rate" attitude there will be the same as the VERB 49 inertial attitude updated at 131:10, which means we'11 change that to - from "171" on the inertial to "177." Over.
CC: Okay. And I have a camera photo pad for you. Pan camera. Go to T-start at i -
CC: T-start, 130:18:05; T-stop, 130:19:16. Over.
CMP: Understand. Pan camera photo pad T-start, 130:18:05; T-stop, 1BO:lg:16.
CC: Roger. And I have a TEI-B7 pad for you if you can find a copy of a pad.
CMP: Roger. I have a TEI-37 pad. Is there any change? --
CC: Roger. Yes, there is a change.
CMP: Okay, Go ahead.
CC: Roger. It's TEI-37, SPS/G&N; 37350; plus 0.60, plus 1.01; at NOUN 33, 150:59:30.08; NOUN 81, plus 2979.1, minus 0748.6, minus 0219.6; 180, 109, 349; and the rest of the pad is unchanged. Ullage, two Jets for 17 seconds; and other comments - longi- tude at T. will be minus 179.22. Over. lg
CMP: Roger. Understand TEI-37 pad, SPS/G&N; 37350; plus 0.60 plus 1.01; 150:59:30.08; plus 2979.1, minus 0748.6, minus 0219.6; 180, 109, 349; two Jet, 17 seconds, and longitude T. is minus 179.22. xg
CC: Roger. Readback correct; and that's the end of the updates for the moment.
CMP: All righty.
CC: And, Endeavour; we'd like to get the callout which was at 129:50 for the gamma ray gainstep to shield off. Over.
CC: And, we, - you can get that most anytime soon. For 10 minutes; it is not critical yet, I guess, as far as the start time is concerned.
CC: Go ahead, Endeavour. g,mma
CMP: Okay, the DELTA-T on the ray boom retract was 3 plus 07.
CC: Copy. Thank you.
CC: And, Endeavour; Houston. When you have a moment, HIGH GAIN in AUTO now.
CMP: Okay. Going AUTO. And do you want the onboard read-outs now, Bob?
CC: Yes. We'11 take them.
CMP: Okay. Crew status. Better than most, I guess. PRD was 23135. Battery C, 37; pyro bat A, 37; pyro bat B, 37; RCS in order, 71, 69, 70, 71.
CC: Okay. We copy all those.
CMP: Okay; and cryo fans have been cycled.
CC: Roger. And the people down here are suggesting that on your presleep checklist, we omit the direct 02 to ON for the rest of your solo flight because you aren't Just breathing down the cabin that much, and I guess it will save a little bit of oxygen and eliminate the possibility of crack- ing a relief valve there. So we'11 delete that section from your -
CMP: Okay, Bob, that sounds good. I didn't notice. Yes, okay, I noticed last night I set it at 5.7, or it was very close to 6, and it didn't drop a bit during the day today.
CC: Roger. I guess that's what we're noticing too.
CMP: Incidentally, Just going over the Littrow area again. I described the - what looked some - some, at least, fumarolic vents. They look like small cinder cones to me. And every time I look at them, they - that firms up my impression more and more that they're vol - volcanic cinder cones. Also, I noticed one rille, and I'd like to try and get some pictures of it here before we get too far away from Littrow on the next - maybe tomorrow. Looks very distinctly like the roof, or the - the top of the rille is collapsed in some places, and the rille is exposed in other places.
CC: Roger. It'11 make a few theorists pretty happy about that.
CMP: Yes, Yes; it might - it might confirm some things about rilles. It's - its a little difficult to see whether it is in fact a collapsed feature in some of the - in those parts of the rille, or whether it's something else that I'm seeing. But it looks very much like portions of - the - the rille have a collapsed roof. And, in fact, the one I was looking at, works it's way into what looks like one of the - one of the ridges. It was very ridgy to the - to the north and then turned into a - a rille as it went south.
CC: Roger. Copy. Keep talking like that, and we might end up going to Littrow sometime.
CC: And, Al, already you've generated enough interest for people to ask if it's underneath you, so that the mapping camera might be getting it now.
CC: Yes. The mapping camera should be getting it.
UNKNOWN: I suspect the - the mapping camera might not have enough detail to - to pick it up as well as we'd like. Although, I don't know, I can see it with the - with the 10-power binocular without any trouble.
CC: Copy. And, Just so we don't forget it, we got about 3 minutes to T-start for the pan camera.
CMP: Roger. Right with you. Countdown 2:50 now.
CMP: Okay, Houston. That - that does the pan camera pass over Hadley Rille, and you can let me know when the lens is tucked in.
CC: And, Al, we verify the lens is tucked. You can turn the power off.
CMP: All righty; thank you, sir. APOLLO 15 AIR-TO-GROUND VOICE TRANSCRIPTION
CC: And, Hadley; this is Houston. Over.
CDR-LM: Go ahead, Houston,
CC: Roger. We noticed over the last half hour or so, a 25-pound drop in the water quantity. We're wondering if you guys have been doing something. Know anything about that you could clue us in on?
CDR-LM: Roger. We Just recharged both PLSSs.
CC: Roger. Was that in the last hour and a half?
CDR-LM: Roger. This was in about the last, oh, 30, 40 minutes.
CDR-LM: Does that fill the gap for you?
CC: Go ahead, Hadley.
CDR-LM: Okay. We've got a crew status report for you.
CDR-LM: Okay. No medication, and the PRDs on CDR is 5019, and the LMP, 8023. Both PLES - PLSSs took their recharge well, and I think they're ready to go for tomorrow. And I guess we're done for the day, so wetre going to roll up the shade.
CC: Roger, Dave. And one last comment to give you a good night's sleep. That little water leak you guys saw when you came in the cabin this afternoon. Right now, our plots are showing that as 25 pounds. Do you guys care to make any comments about the size of the leak, or anything more about that?
CDR-LM: Fine. No, except that, when we got in, that little plastic connector on the - yes on the bacteria filter was broken and there was water running out of it.
CC: Roger; understand. More or less a steady stream?
CDR-LM: Yes. That's about right.
CC: Roger. Copy. And I guess we're steady now, and you can go to sleep on that note. We won't promise, but we'11 try and not wake you up this morning.
CDR-LM: Well, if you see something that you'd llke to look at, we'd rather have you wake us up.
CC: Yes, I'm sure.
CC: Okay, Dave. I think we've said all we want to say on that, and I don't think there's anything else you can do about it at the moment, and we'11 Just let it go.
CDR-LM: Okay. What does that do $o our profile on the water?
CC: We're looking at it, Dave. It looks like it puts us a little bit closer to red line, but it's still above the red line.
CDR-LM: Okay, fine. See you in the morning. Thank you.
CDR-LM: Good night.
CC: And, Al, while you're getting ready for the mapping camera, if you'11 let us, will get an E-memory dump.
CMP: Okay, Bob. Stand by 1.
CC: And, Al, we're noticing the laser, I guess - Vance told you earlier, it's kind of going downhill a little bit, and we'd like to turn it off at this time. It's working about 50 percent right now, so we'd like to turn it off right now. spec boom is coming out.
CMP: Okay, Bob. I've got some good accurate times for you on the boom extensions.
CMP: Okay. It's from switch actuation to - when the And barber pole goes gray. the DELTA-T for the mass spec was 2minutes 39 seconds, 2 plus 39, and the DELTA-T for the g_mma ray was 2 plus 41, 2 plus 41.
CC: Roger. We're looking at your torquing angles and you're GO.
CC: Roger. One small change to your Flight Plan. Reminder of the change that we made yesterday, as well. At 133:17, remember the mass spec peoples now want DISCRIMINATOR and MULTIPLIER to LOW. You remember that?
CMP: Roger, Bob. I've got it. It's showing in LOW at 133:17.
CC: Roger. Just a reminder. And another reminder: when you get ready to go to sleep, you can go to REACQUIRE and NARROW with plus 25 and 185, and then we won't disturb you when you come around AOS on the pass after next when you should be - already asleep, r
CMP: Roger. Understand high-gain angles are plus 25 and 185.
CC: Roger. i think they're in your checklist too, Al.
CMP: They could be, Bob. I looked for them last night and couldn't find them.
CC: I figured as much. And
CMP: Roger. incidently, the DELTA-T on the mapping camera retract was 3 plus 15.
CC: And, Endeavour, as you go around the hill, good night.
CMP: Okay, Bobby. Good night. REST PERIOD - NO COMMUNICATIONS
CC: Hello, Endeavour; this is Houston. Over.
CC: Hello, Endeavour. Endeavour, this is Houston. Over.
CC: Hello, Endeavour. This is Houston in the blind. If you read, go REACQ and NARROW at angles of PITCH, plus 25; and YAW, 185. That's PITCH, plus 25; and YAW, 185. Over.
CMP: Hello, Houston; this is Endeavour. Go ahead.
CC: Okay, Al, this is Houston. You're loud and clear now. I would like to suggest going to the presleep configuration before you bed down for the night there on the comm.
CMP: Yes. Roger. Will do, Gordo.
CMP: Yes, go ahead, Gordo.
CC: Okay. If you've gone through the presleep cheek- list, we noticed a couple of things. The optics power should go off, and also - in your DAP load, go to all l's in R-1. And, we'd like a call when you finally turn in and turn the voice mode off, Just before you do that, please. Over.
CMP: Yes. Okay, Gordo. Haven't been through the checklist yet.
CC: Endeavour, Houston. No need to acknowledge, but we need the MASS SPEC, DISC - DISCRIMINATOR to LOW as per an earlier update. Over.
CMP: Gordon, was that MASS SPEC, DISCRIMINATOR, LOW, or MULTIPLIER, LOW? I got an update about 5 hours ago. It was - They saidMULTIPLIER, LOW.
CC: Okay. I guess the update was on the DISCRIMINATOR. Actually, they're both supposed to be LOW, MULTI- PLIER and DISCRIMINATOR, Al.
CMP: Okay. I tmderstand you want them both LOW.
CC: That's affirmative. APOLLO 15 AIR-TO-GROUND VOICE TRANSCRIPTION REST PERIOD - NO COMMUNICATIONS
CDR-LM: Morning, Houston. This is Falcon.
CC: Roger, Falcon; Houston. Loud and clear. And when you're up and ready to converse, let me know.
UNKNOWN: Okay, Gordo. Will do.
CC: ... First thing we've been concerned about - I guess we'11 start off with this is, according to our data, you lost about 25 pounds of water during the post-EVA yesterday, and, we - it - it appears that it leaked out during that problem you had with the broken bacteria filter. What we're wondering is if you've looked around carefully in the cabin, and noticed any sign of that 25 the ascent engine cover, because it possibly would have run back there and not have been obvious to you. Over.
CDR: Okay. There was some on the floor in the ... deck, and we Just never took the time to take a look in the back, but we will.
CC: Okay. If you find - any water back there, we have some suggestive procedures to clean it up, and we'd like to do that before depressurization.
CDR-LM: Roger. Will do.
CDR-LM: Oh, Houston, Falcon. Yes, we do have a little puddle of water back in the - behind the ascent - behind the engine cover. 90/1 Tape
CC: Okay, Dave. Our suggested procedure for collecting that will be to remove the netting and whatever is required to get down to it. Use a used food bag as a scoop if it's a deep enough puddle to scoop it up and take one of the used LiOH containers that contains a used cartridge that's in the buddy SLSS bag now that's scheduled for the upcoming Jettison. Take the LiOH cartridge out of the con- tainer, then use the container itself to hold the water as you scoop it up with the food bag. And then when you get down to the point where you can no longer get any more water, use utility towels to mop up the rest. Over.
CDR-LM: Okay. We'11 do our best.
CC: And if one of you is not - busy, I do have a pad with the lift-off times for rev B2 to 37.
CDR-LM: Standby.
LMP-LM: Good morning, Gordo. I'm ready to copy.
CC: Okay, Jim. One more tidbit on the water problem. If - according to our figures here; that ETB bag that has your - the cameras and film you are going to use on the next EVA may be back there where the water is, and we suggest you get it up out so it won't get wet. Over.
LMP-LM: No. That's - that's taken care of.
LMP-LM: Okay, Gordo. I'm ready for the pad.
CC: Oh, okay, Jim. T-32 is 140:10:24; T-33, 142:08:B3; 34 is 144:06:40; 35 is 146:05:03; 36 is 148:02:57; and 37 is 150:01:04. Over.
LMP-LM: Okay. 140:10:24; 142:08:33; 144:06:40; 146:05:03; 148:02:57; and 150:01:04.
CC: Okay Jim. Your readback's correct. And, Jim, one other question. If - if you can remember back to before you went to sleep, this is in reference to the problem you had with the flags at the start of the EVA-l, and we're 'figuring that that was probably caused by an air bubble that was in your PLSS feed water system. We're wondering if, when you're- charged the PLSS feed water here after EVA-l, were you holding the PLSS in a vertical position? That would eliminate any possibility of a bubble and we wanted to verify if that was the case or was it tilted over somewhat.P Over.
UNKNOWN: It was tilted over slightly when we recharged after EVA- 1.
CC: Okay. Stand by, and I'11 see if we want to re- charge it or something. We'11 check on what they want to do. Can you give us a rough idea of what sort of angle it was tilted at and in which direction?
CC: Jim, this is Houston. Over.
UNKNOWN: GO ahead, Gordo.
CC: Did you copy my last question about - I'11 repeat it. Can you give us an estimate of how far off of vertical the PLSS was in degrees, roughly, when you did fill it? Over.
LMP: It was about 30 degrees off vertical when we charged it.
CC: That 30 degrees is probably enough to cause the problem you saw at the start of EVA-l, and we may, depending on how you do with cleaning up the water and so forth, want you to re - top-off the water and maybe the oxygen also on both PLSSs. We'11 have more on that later. I do have a consumable update for 138 hours, when you are ready to copy.
LMP-LM: Okay. Go ahead, Gordo.
CC: Okay. RCS Alfa, 85 percent; Bravo, 85; descent 02 number l, 71.5; number 2, 68.4; ascent 02 num- 42.3; number 2 is 40.2; ascent water, number l, 100 percent; number 2, 100 percent; and descent amp-hours are 1157; ascent amp-hours, 572. Over.
LMP: Roger. I copied all that.
CC: We've got some conversation to come up to you're- garding to some - some updates to the EVA prep and also about the EVA traverse plans, and if that would fit in with what you're doing, let us know and we'11 go ahead and give those words to you. Over.
LMP-LM: Well, Dave is off corn right now, so I don't want to talk about the EVA plan or the traverse plan, but maybe EVA prep, I can talk to you about.
CC: Okay, Jim. If you get a piece of scratch paper here, I'11 give you the - the camera magazines that we figure should be in the ETB and on the cameras at the start of this. They've changed slightly from the - what you loaded last night. Over.
LMP-LM: Okay. Did - did Dave tell you what we had loaded last night?
CC: I'm not sure; I'11 have to check on that.
LMP-LM: I don't think we - we have the ETB loaded, and let us tell you what we have in ETB.
LMP-LM: Okay. The ETB is loaded per checklist and the additional MAG is MAG Papa.
CC: I understand that's Mag Papa, is that correct?
CC: Okay. Let me cross-check that here and see if we can get anymore words on that. Let me give you one other suggestion and that's for securing the high gain antenna cable on the Rover. We'd like to suggest that you get the roll of tape out, strip off about 1 foot, and fold a 1- to 2-inch tab on one end of it and wrap that piece of tape around the CDR camera so that after you get down on - to the Rover you can use it to secure the high gain anten - cable to the high gain antenna mast and keep it from flopping around. Over.
CC: Jim, this is Houston. Did you copy that about the tape?
LMP-LM: Yes, we copied. _
CC: Okay. One other thing is we suggest that you each wear your EVA-1 cuff checklist on your right arm for use at the end of EVA-2. That's for both of you. Over.
LMP-LM: Oh, yes. We've already put that in ETB.
CC: Okay. And can you give us a post-sleep status report there?
LMP-LM: Well, we both slept for the full time, and we'11 get the PRD readings if required in a little bit.
CC: On the ETB load camera stuff, we'd like you to add Delta Delta - 16-millimeter MAG Delta Delta to the bag, and also, if you have your camera loaded with Kilo Kilo, we'd like you to take it off, put Kilo Kilo in the bag, and put Papa Papa on your camera. Those are the only two changes that we see from what we figure you have right now. Over.
LMP-LM: Let me Jot down your recommendations again. Say again.
CC: Okay, Jim. Add 16-millimeter MAG Delta Delta to the bag load first of all, and then on your 70- millimeter camera, that's the LMP 70-millimeter camera, take Off - we assume - that Kilo Kilo is on it now. We'd like you to take that off and put Papa Papa onto your camera. Over.
LMP-LM: You're suggesting we take 16-millimeter Delta off and take MAG K off my camera and put Papa on my camera, but probably carry Kilo out with us.
CC: That's affirmative, Jim. Carry Kilo Kilo with you, and I think you said - said it right. But take Delta Delta along, also, in the bag. Over.
CC: Jim, Houston. Over.
LMP-LM: Hello, Houston; Hadley Base.
CC: Okay. A couple of questions. First of al4we wondered if you have brought up the LGC and cycled it through program 6 there. We haven't got high bit rate and we haven't been able to tell. The other one was how is the water clean up going and can you estimate how much you're able to scoop up there. Over.
CDR-LM: Okay, Gordo. Two answers. Yes, the program - your computers have cycled, and all of the water is cleaned up and we've got two full LiOH canis- ters plus about 1/8th of the CSM helmet bag.
CC: Okay. I'11 get a suggestion here for what to do
CDR-LM: Roger. It looks like with all the stuff we have to throw over today, we're going to have to use another jettison bag.
