[As John prepares to go out through the hatch, he and Charlie are on cuff checklist pages CDR-4 and LMP-4, respectively.]MP3 Audio Clip ( 5 min 35 sec )
142:44:33 Duke: Okay, Houston. We're gonna get out.
142:44:35 England: Okay, we understand your water flags are cleared.
142:44:40 Young: That's correct.
142:44:41 Duke: John's is; mine's not quite, but I feel good cooling. (Pause)
142:44:48 Young: (To Charlie) (Can you) back up a hair?
142:44:50 Duke: No.
[Charlie is behind the hatch and, apparently, is unable to move enough to open the hatch any farther.]142:44:54 England: Okay, John, you're Go for egress. Charlie, we'd like you to stay.
142:44:56 Duke: Okay, mine just flipped.
142:44:58 England: Okay, fine. You're both Go for egress. (Pause)
142:45:05 Young: (To himself) God damn hose is got in my way. (Pause)
142:45:14 Duke: Okay, John. You're doing great. You got to come towards me a little bit. There you go. (Pause) Okay, you've got to swing your rear end towards me. There you go. Now your PLSS is out the door. Bend over a little bit, so you don't catch your harness (on the bottom of the DSKY). There you go. (Pause) You're okay.
142:45:38 Young: Okay. (Long Pause) Okay, Charlie. Hand me the jett bag.
142:45:55 Duke: Okay. Stand by. (Long Pause)
[Charlie probably closes the hatch, moves to John's side of the cabin, re-opens the hatch, and pushes the jett bag out to John, who drops it to the surface. I am not absolutely certain as to the speaker IDs for the next two lines and it is possible that it is Charlie who speaks next.]142:46:15 Young: Hit the strut with it.
142:46:17 Duke: Yeah.
142:46:18 Young: Didn't hurt the strut.
142:46:19 Duke: No. Okay, here's the ETB.
142:46:22 Young: Okay, give me...
142:46:24 Duke: I don't want to throw it too hard (through the hatch) with the cameras in there.
[It is possible that Charlie puts the ETB on the floor and pushes it out with his foot.]142:46:27 Young: Okay.
142:46:29 Duke: There we go.
142:46:30 Young: (Garbled) (Pause) Wrap it around this finger.
142:46:35 Duke: Okay. (Doing the tasks on LMP-4) Recorder's Off; Vox is in Max; utility and flood(light)s. Okay, get the floods off. Utility's off. (Pause) And these look okay. (Pause) Coming over to this side, I think. There we go. (Pause)
142:47:06 Young: Okay, Houston. What do you want to do with the (UV) camera?
142:47:09 England: Okay. We'd like you to go over and describe to us where the Sun is with respect to the UV.
142:47:18 Young: I could have done that standing in the vehicle.
142:47:23 England: Well, we're going to have you move it back, but we just wanted the data before you move it.
142:47:35 Young: Charlie, watch out for the big rock in the footpad.
142:47:38 Duke: Yeah, I know it. I put it there. That's Old Muley ( 172k ).
142:47:47 Young: Charlie, is my visor down? I can't (garbled)
142:47:51 Duke: Wait a minute.
142:47:52 Young: Never mind, never mind.
142:47:54 Duke: (Looking out the window) Your protective one; I don't know about your...
142:47:56 Young: Okay, I got them both down. The other one.
142:48:00 Duke: Okay, mine are down. Okay, Houston; I'm out on the porch.
142:48:07 England: Okay, Charlie. (Pause)
142:48:11 Duke: Okay, got to go back and close the hatch.
142:48:15 Young: Okay, the Sun is just...At this setting, the Sun is slicing off about 2-1/2 to 3 inches of the...It's slicing off half of the spectroscope box. You know what I mean?
142:48:40 England: Okay.
142:48:41 Young: It slices right across there.
142:48:43 England: Okay, the Sun is on the film cassette, is that right?
142:48:48 Young: It is on the spectroscope. The spectroscope box that hooks out. It's the optical part.
142:49:01 England: Okay, we'd like you to move the UV camera in the east direction, directly east, so that it's 1 foot behind the plus-Z pad. Reset before you move it.
142:49:20 Young: Okay. (Pause) Okay. (Pause)
142:49:29 Duke: (Doing his W.C. Fields voice) Okay, Tony, I'm on the old lunar terrain again.
142:49:33 England: Very good.
142:49:35 Young: Do a reset?
142:49:36 England: Okay, you do a reset and move the camera in the east direction until it's 1 foot behind (that is, east of) a line that goes north-south through the plus-Z footpad.
142:49:52 Young: Okay. (Long Pause)
MP3 Audio Clip ( 0 min 19 sec )
[Charlie's first task is to set SRC 2 on the MESA table, open it, and seal a control sample consisting of a roll of clean aluminum metal in a sample bag and place it in the SRC. With regard to Charlie's next transmission, launch was at 11:54 a.m. Central Standard Time, 16 April 16 1972. It is currently 10:44 a.m. on the 22nd and Charlie's transmission confirms that his wristwatch is set to Houston time. He is probably using the stopwatch function to time the EVA.]142:50:06 Duke: Oh, quarter to 11. (Long Pause)
MP3 Audio Clip ( 2 min 53 sec )
142:50:26 Duke: Man, that thing really pops open.
142:50:30 Young: Okay, Houston, she's moved.
142:50:32 England: Okay, re-level it there, and then we're going to give you a target to aim at the Earth. Settings for aiming at the Earth. (Long Pause)
142:50:59 Young: Houston, this really isn't too very good for me to do this because I can't get my backpack between it and the strut to operate it. Did anybody try this in the real world? (Pause)
[John is asking if Fred Haise or someone else got a suit and backpack on and tried to operate the camera this close to a LM mock-up.]142:51:22 England: Negative, John. If you have to move it south a little bit, it's safe to move it to the edge of that shadow.
142:51:36 Young: Okay, let me do that. (Pause) Okay, it's re-moding now. We're going to lose whatever we're doing here.
142:51:53 England: Okay, that's fine. We understand. (Long Pause)
142:52:33 Duke: (Adjusting the MESA height) Hey, John, that's better. I moved the MESA back down and, man, it's super nicer. Don't have to fight the suits. The SRC-1 is open. Hey, what I'm going to do, Tony; I'm going to bring up the TV for you.
142:52:53 England: Okay, when you push in the circuit breakers, would you read us the battery temperatures?
142:53:01 Duke: Okay, all the breakers are going in. And the battery temps are, one, 65, and the other is 82. Correction...One, 70, and the other is 82.
MP3 Audio Clip ( 2 min 39 sec )
142:53:22 England: Okay, 70 and 82.
142:53:27 Duke: Okay, what's next, for the TV?
[Charlie has nothing to do until John finishes with the UV camera. Charlie doesn't have the TV procedures on his checklist and didn't training for them on a regular basis. He is asking Tony to talk him through the procedures.]142:53:32 England: Say again, Charlie.
142:53:36 Duke: What is the next switch setting for the TV? It's not on my checklist.
142:53:46 England: Okay, LCRU switch, Mode 1 (PM1/NB).
142:53:53 Duke: Okay, go ahead.
142:53:57 England: Okay, position TV horizontal and counter-clockwise to (the) stop. (Pause)
142:54:06 Duke: Okay, go ahead. (Pause)
142:54:13 Young: Okay, Houston, the (UV) camera is re-leveled. Camera is re-leveled, Houston.
142:54:21 England: Okay, John, we'd like you to...
142:54:22 Young: Now, what else did he say about this?
142:54:23 England: John, we'd like you to aim it at the Earth. The azimuth is 058 (roughly northwest), elevation is 75.
142:54:34 Young: Roger. (Pause)
142:54:42 Duke: Okay, Tony, what else on the TV, please?
142:54:44 England: Okay, just go to Mode 3 on that and we'll leave it there. And we'll control it from here.
142:54:50 Duke: Okay, will you have a picture? (Hearing Tony) Okay.
142:55:01 England: Okay, John, with that azimuth and elevation, look through the Earth sight and center it on the Earth, then give us the azimuth you are reading and from that we'll calculate a new target.
142:55:20 Duke: Okay, y'all are just about dead center, Tony, in the high gain (antenna sighting scope).
142:55:26 England: Okay, fine.
142:55:32 Duke: You ought to be getting a picture.
142:55:34 England: Okay; and, Charlie, go External on the LCRU (Power) switch.
142:55:40 Young: What was the elevation setting, Tony?
142:55:44 England: Okay, the elevation is 75. (Pause)
MP3 Audio Clip ( 0 min 11 sec )
142:55:55 Duke: Okay. I copy that External.
142:55:56 England: Okay.
142:55:57 Duke: It is External.
142:56:00 Young: Okay, Houston; I'll tell you what...
MP3 Audio Clip ( 0 min 17 sec )
142:56:09 Duke: There. Now it (meanding the LCRU Power switch)'s External. It was Off. (Pause) Okay, your power (meaning the LCRU signal strength) is up to 4, Tony; I mean your S-band AGC (Automatic Gain Control meter) is to 4 and you're External. It was Off; I'm sorry.

[TV on.]142:56:23 England: Okay. (Long Pause) And we've got a picture.
[The TV camera is pointed WSW. Charlie crosses the field-of-view, heading for the back of the Rover where he will attach two SCBs as per LMP-5. The TV picture moves slightly as he works and, after a moment, we get a glimpse of his shadow at the bottom of the TV picture.]

[The comm improves dramatically.]MP3 Audio Clip ( 3 min 58 sec )
[Young, from the 1972 Technical Debrief - "Charlie recommended that we put the (TV/HGA) alignment in both (cuff) checklists so that either guy could do it."]
[Duke, from the 1972 Technical Debrief - "I had to interfere with John's conversation with Houston (at the start of the EVA) to get that going. But it's a place to save time, because the LMP really doesn't have that much to do on the (LRV) load-up. Get the cameras configured, and the film stowed, is about all. So, it's good to have some kind of cross-talk within the checklists so you don't have to interfere with the other guy. Apollo 17 probably won't have that problem with it since they don't have the UV (camera); but, sure enough, something will be there. And, so, they really should have those TV and LRV power-up procedures in both checklists."]
[Apollo 17 Commander Gene Cernan did not have any time-consuming tasks like the UV camera planned for the early parts of that mission's EVAs and the TV procedures were not included in LMP Jack Schmitt's cuff checklist.]
[Jones - "During the last few minutes, John was resetting the UV, you were resetting the TV and Tony was trying to give instructions to both of you, simultaneously. Do you have any comments about this? In the Apollo context, where seconds and minutes were precious, was ad-libbing a noticeable distraction?"]
[Duke - "Well, it was hard. We kept stepping on one another, comm-wise, at times. You had to balance it out. Normally, you wouldn't want to do that because you just want to stay with your checklist. But John was supposed to power up the TV and I was supposed to get on with the rock boxes and stuff; but he had this problem with the UV camera. And, so, I just decided to go turn on the television. Normally, you wouldn't want to do that, because it is confusing. Your stepping on one another and the CapCom's trying to talk to both of you and 'what'd you say' - especially when the comm's bad. It wasn't a good idea all the time; but, in this case, instead of me just standing around twiddling my thumbs, I'm getting something done. So, it was a balance; you had to make a decision whether to go ahead and do something or just stand there when the other guy has something else he's supposed to be doing that's out of the ordinary."]
[Jones - "With improvements in electronics since then, would it make any sense, in the lunar base era, to have separate comm? What do they do in the Shuttle?"]
[Duke - "I don't know. They have one CapCom for the major operations, but there might be somebody in the science room. And I think that's probably a good idea. You know, you're probably going to have one frequency for the home base and another frequency for some group that's going out west and another group may be going south; so you'd want different comm for them and different people monitoring. And then, like you do flying airplanes, you'd want some common emergency frequency that you could switch to and talk on that everybody's monitoring but nobody's talking on. Military comm is like that. You have a UHF radio that you're talking on one frequency, but you can receive on this emergency frequency or your regular frequency. But then, to transmit, you've got to turn to the emergency frequency."]
[Jones - "But, to receive, you don't."]
[Duke - "No, you don't. I think something like that would be pretty beneficial. Of course, it depends on the scope of operations up there; but if you're going to stay for thirty days and have people running all over in different Rovers and stuff like that, you're going to need something."]
[Jones - "Conceivably, one person back in Houston to talk to each individual, if necessary."]
[Duke - "Yeah, well, I would probably say it's going to be somebody out on the lunar surface in the home base, maybe, talking. It would be very expensive to keep Mission Control manned for six months or so, but I don't know. You know, that's going to be a real big decision area: how are you going to manage this thing? Are you going to do it all on the lunar surface or are you going to go back to Earth?"]
[Jones - "And you certainly can't run it on a second-by-second basis when you're on the Mars missions."]
142:56:45 Young: Okay, Houston; the Earth is in the center and the (UV) camera's re-leveled.
142:56:56 England: Okay, would you read off the azimuth now?
[Fendell begins a clockwise pan.]142:57:08 Young: Well, I left the azimuth on there and leveled the camera and put the Earth in the center. How's that? Is that...
142:57:15 England: Okay, that sounds fine and the azimuth is 058.
142:57:21 Young: 058 and (an elevation of) 76.
142:57:25 England: Okay, then the first target will be 112 and 40.
[This target is roughly 20 degrees east of north and, because John is south of the ladder, it seems unlikely he will be able to see the target past the LM.]142:57:33 Young: 112 and 40. (Pause) You want to do a reset after we get to that target, right?
142:57:43 England: That would be fine. And when you do a reset, verify the film advances and read the tempa-label for us.
142:57:54 Young: Okay.
[A tempa-label is a patch with a series of spots which change from white to black at successively higher temperatures. A detail from Apollo 16 training photo KSC-71P-111 shows a tempa-label on the handle of a UHT.]142:57:55 England: That's the tempa-label on the film cassette.
142:58:00 Young: Roger. (Long Pause)
[As Fendell reaches the clockwise stop, we get a glimpse of John working with the UV camera near the ladder. Charlie is at the back of the Rover and is unfolding an SCB.]142:58:30 Young: That's going to be pointing right at the lunar module, Houston!
142:58:34 England: Okay, then move it to the left (counter-clockwise) until it is clear of it.
142:58:37 Young: (Garbled) (hears Tony) Oh.
142:58:43 England: Move it in azimuth.
142:58:52 Young: You want me to move it to the left until it's clear, but I've got to take it out the other side of the vehicle.
142:58:57 England: Move it in azimuth.
142:58:58 Young: I got to take it to the north of the vehicle.
142:58:59 England: Not the camera.
[Charlie drops the bag, puts his left hand on the top of the Rover gate and bobs down to retrieve the bag.]142:59:04 Young: Okay. Thank goodness, you said that. I was about to pick this thing up.
Video Clip ( 2 min 49 sec 0.7 Mb RealVideo or 25 Mb MPEG )
142:59:12 England: Sorry about that, John.
[Comm Break]143:00:24 Duke: (Working at the back of the Rover behind John's seat) There's no way to get that out (garbled). (Long Pause)
[After Charlie attaches the bag to the gate, he puts in two core tubes. Figure 99 (S88-52671) in Judy Allton's Apollo Toolbook shows an SCB with two core tubes stowed in interior pockets.]
[In Houston, the Flight Director is told that the UV experimenters want to change targets. Quite properly, he decides not to bother John and says that they will "press on" with the mission.]
[As per LMP-5, Charlie is trying to get either a sample bag dispenser or a core cap dispenser. He then removes the two core tubes he just placed in the SCB.]MP3 Audio Clip ( 1 min 05 sec )
[In Houston, the Flight Director tells the UV experimenters that he doesn't want them to select targets where there is any chance that the camera will be pointed at the LM. "We're wasting time, here."]
[Charlie seems to get a sample bag dispenser out of the SCB and then re-stows the core tube.]
143:01:03 Young: Okay, Houston, I think we're (aimed) clear (of the LM) now.
143:01:05 England: Okay, good show. Hit reset, watch the film.
143:01:10 Young: But it's reading 080 (degrees azimuth), Houston. (Pause) Is that okay?
[The camera is pointing slightly west of north and not northeast. If they stay with this pointing, in essence they will be looking at a random piece of sky.]143:01:25 England: Stand by a second, John. Why don't you read that tempa-label to us (while a decision is made)?
143:01:34 Young: On the battery?
143:01:35 England: No; that's on the film cassette.
143:01:41 Young: Okay. The tempa-label on the film cassette is black at a 100 degrees F.
[In Houston, the Flight Director relents and allows the UV experimenters to pick a new target.]143:01:48 England: Good show. That's good news. I hate to do this to you, John, but we're going to have to change targets. We'd like to go to azimuth 317.
Video Clip ( 3 min 01 sec 0.8 Mb RealVideo or 27 Mb MPEG )
143:01:59 Young: Okay, 317. (Long Pause)
MP3 Audio Clip ( 0 min 17 sec )
[Charlie comes around to the LMP seat and puts something down. Whatever it is, it is not large enough to be a bag dispenser.]143:02:15 England: And elevation, 51. (Long Pause)
[This target is in the southwest direction.]MP3 Audio Clip ( 11 min 31 sec )
[Charlie returns to the back of the Rover, gets an SCB and takes it to the LMP seat. He then examines his checklist and goes to get the ETB, which has been hanging from the front edge of the MESA. During the following conversation between John and Tony, Charlie takes the ETB to the CDR seat. Note that, as per CDR-5, John was supposed to have unloaded the ETB. Charlie does not have the details on his checklist but, probably having watched John do it often enough in training, doesn't have to call Tony for instructions]
143:02:46 Young: Okay, 317 at 51.
143:02:49 England: Okay, hit reset and watch the film; if it advances, we're through with it for now.
143:03:00 Young: Oh, boy; it advanced! Over 120...Almost 180. (Lost under Tony)
143:03:06 England: Good show. That's the way it should go. Now we'd like you to turn around and look at the cosmic ray for a second.
143:03:10 Young: Okay. (Hearing Tony's request) Get turned around and looked at the cosmic ray.
143:03:16 Duke: (In his W.C. Fields voice) Turn around and lookit the cosmic ray.
[John has turned to face east and walks to the cosmic ray experiment, which is out of our view on the south side of the spacecraft.]143:03:19 Young: That's a nice cosmic ray and...
[Fendell starts panning counter-clockwise.]143:03:21 England: Okay. (Chuckles) In the top panel...
143:03:24 Young: Where's this...(Stops to listen)
143:03:25 England: ...in the top panel when you pulled that...
143:03:27 Young: Yes?
143:03:28 England: ...ring, (John laughs) a piece of tinfoil should have slid up so there's only a 2-by-2 flap in the upper left-hand corner. Can you see that tinfoil?
[Before John and Charlie start the drive to Stone Mountain, Charlie takes two pictures of the Cosmic Ray Experiment, AS16-107- 17441 and 17442.]143:03:45 Young: (Mulling the question) There's only a 2 by 2 flap in the upper left-hand corner. Yeah, but it's more than 2 by 2; it's about...There's a hole that's covered up. There's a hole up there, and it's covered up in the upper left-hand corner, or almost covered up.
143:04:06 England: Okay. Understand that. That should be right.
143:04:11 Young: It's almost covered up.
143:04:13 England: Could you describe how it's almost covered up? Which part isn't covered?
143:04:19 Young: The bottom part of the hole is almost uncovered. I'd say the bottom one-fourth of the hole is not covered.
143:04:34 England: Okay. That's good news, John. That means you deployed...(Choosing a more diplomatic phrasing) It deployed fine. We'll get a picture of it later from Charlie, and if you could go about your nominal work now. (Pause)
Video Clip ( 3 min 03 sec 0.8 Mb RealVideo or 27 Mb MPEG )
143:04:54 Young: Ah, the old water bag is working super! This is going to be a good day, Charlie.
143:04:58 Duke: Good. (Pause) (Doing his W. C. Fields voice) Ah, the old commander's camera. Right down in the old dust. (Normal voice) That's on the floorboard; that's not onto the ground. (Pause)
143:05:15 Young: Okay. (Laughing) I wonder what my nominal workload is at this point.
143:05:22 Duke: I don't know.
143:05:24 Young: We're supposed to be at Station 4, Charlie.
[Although John is aware that he lost a lot of time because of the UV camera, he sounds relaxed and, obviously, is not in a mood to complain.]143:05:27 Duke: Just like in training, John...
143:05:29 Young: Yeah.
143:05:31 Duke: ...I'm licking the orange juice off (the inside of) my visor.
[Fendell finds Charlie at the CDR seat. He is holding the ETB in his left hand and is reaching in with his right. He pulls something out - probably a film magazine - and stows it under the CDR seat.]143:05:38 England: And, Charlie, when you're taking that pan, let me know. I have another picture for you.
143:05:45 Duke: All righty!
[John comes up behind Charlie from the back of the Rover but, during the following is out of view while he works on the right side of Charlie's PLSS.]143:05:47 Young: Okay, Charlie, hold still a second and let me get your old PLSS strap tie-down on here a little bit.
143:05:53 Duke: Old PLSS strap tiedown.
143:05:59 Young: Man, that's really bad there. (Long Pause) (I) don't know how a growing boy could get his straps so messed up in one little EVA. (Pause)
[John comes around to the left side of Charlie's PLSS to check that part of the harness.]143:06:26 Duke: Oh, the old dark slide. Coming out! Expose one picture. Okay.
[Charlie has just withdrawn the dark slide from a film magazine, installed the magazine in the 500mm camera, and then advanced a frame so that the next picture will be on unexposed film. As Charlie works at the CDR seat, we get a glimpse of John as he examines his checklist.]143:06:42 Young: Okay. (Looking at CDR-5) You got the ETB (unloaded). Right?
143:06:46 Duke: Yeah. Just about finished with it.
143:06:49 Young: (Looking at CDR-4) You got the LRV circuit breakers, Bus A, B, C, and D, and Nav closed?
143:06:53 Duke: Yup. No, I didn't close...Yeah, Nav Power's closed.
[Fendell starts to pan clockwise just as John walks toward the front of the Rover, looking at his checklist as he goes. One of the raised battery covers is visible in the foreground.]143:06:56 Young: Okay. The dustbrush is on the LCRU. It is.
143:06:59 Duke: Amazing.
[A detail from training photo KSC-71PC-777 shows the dustbrush stowed on the front of the training Rover.]143:07:01 Young: "Close LRV (batt) covers and press tight." Okay, Houston, the covers are still open, and they don't have any more dust on them than they did yesterday.
143:07:11 England: Outstanding.
143:07:13 Duke: (Joking) Therefore, you have to dust. (Pause) What we need is a dustbrush for the dustbrush.
143:07:26 England: Don't say it, Charlie.
143:07:31 Duke: Say again?
143:07:33 England: I said, don't suggest it.
143:07:38 Duke: Yeah. Somebody will probably log that.
[Tony is warning Charlie that somebody will take the suggestion seriously and design a dustbrush dustbrush for Apollo 17.]143:07:41 Duke: I was just kidding, you guys! What we need is less Velcro. Man! Tony, yesterday when that piece of Velcro...
[Jones - "Were there people in the support rooms listening to this and writing things down that needed to be changed or added. Is that the implication of this?"]
[Duke - "Well, the implication is that somebody might think, 'Oh, yeah, we do need that', and add something else to the stowage list when we were just kidding. But lot of times (in training), though, things you thought of, like that, would result in a change in the procedures or a change to the equipment, because they always wanted to try to make it work right. We were just teasing; but some people take those comments sometimes and say, 'Oh, yeah'; and think it's gospel; and we really didn't mean it that way."]
[Jones - "Did you run into that occasionally? Cases where 'The Astronaut Speaks' and something happens even though you hadn't thought it through?"]
[Duke - "Not without going through the change boards. But if you had something you wanted to change and you fought for it hard enough, they'd usually do it. But you'd have to take it all the way up to the change boards."]
[Fendell has panned to the left and we have a view of Charlie's torso and legs as he works at the CDR seat.]Video Clip ( 3 min 01 sec 0.8 Mb RealVideo or 27 Mb MPEG )
143:07:52 Young: (To Houston) Hey! Can you guys see that dust on there, with the TV?
143:07:56 England: We're not looking down far enough right now.
[Charlie closes John's seat and takes the ETB to the MESA. Fendell shifts his aim down, giving us a view of the battery mirrors just as John pushes the cover closed.]143:07:59 Young: Oh.
143:08:00 Duke: John, make sure that I did all the things on (the ETB unload on CDR-5)...The ETB is emptied, and magazine Lima is on the camera - (the) 500 - and all the other film is stowed.
[A puff of dust flies off the battery cover as it falls shut. John then presses the cover with his right hand.]143:08:11 Young: Whew. Okay. Down and pressed tight.
143:08:17 England: Okay.
[Fendell raises his aim. John is no longer in sight.]143:08:19 Duke: Man, that LPM (Lunar Portable Magnetometer) is a bucket of spaghetti!
143:08:28 Young: You're not messing with it, are you?
143:08:30 Duke: No. I was just...
[After John used the LPM at Station 2, he did his best to rewind the ribbon cable that connects the sensor to the gauge mounted on the back of the Rover. Obviously, he didn't get it wound very neatly.]143:08:32 Young: (To Houston) And as near as I can figure, Tony, what we've got to do now is load up the PLSSs (as per CDR-5) and go get 'em (meaning the rocks on Stone Mountain). (Pause)
[Fendell starts a clockwise pan.]143:08:42 Young: (To Tony) Want me to reset the far UV again, or you just want to be happy with this? All we got to do now is a PLSS load-up.
143:08:49 England: Okay; yes. We have one more target on it. I'm not sure they have enough time, yet. Hold on.
[Tony is probably saying that the UV experimenters may not have been on the current target long enough to have good data.]143:08:56 Duke: Want a minute; I got to get a pan, John. So it'll be a few minutes. Why don't you run around and pick up a rock?
143:09:02 Young: Hey! Outstanding suggestion. Give me a rock bag, Charlie.
143:09:08 Duke: The little ones or the big ones?
143:09:10 Young: Huh?
143:09:11 Duke: Why don't you take your camera?
143:09:12 Young: I will.
143:09:15 Duke: Okay. That...
143:09:16 Young: That's yours, huh?
143:09:17 Duke: Yeah. Well, I got some right here. You use those, and I'll put the old maps...(Rhetorically) Which way are we going today? Hmmm.
143:09:28 England: How about south?
143:09:33 Duke: Let's see, (pretending to read) "Hadley Rille". (Pause)
[During our mission review, Charlie told me that, before the Descartes maps were ready for training purposes, he and John used copies of the Apollo 15 maps. Those, of course, showed Hadley Rille.]143:09:42 England: Okay...
143:09:43 Duke: Tony, this map says "Start at training building."
[This is a reference to training exercises conducted at the Cape.]143:09:48 England: (General laughter in Houston) Okay. Verify that your PLSS antennas are up, and could we have an EMU check first chance? And John, if you're out picking up a rock, you might...
143:09:58 Duke: Our antennas aren't up. How's the comm?
143:10:01 England: Comm sounds good.
143:10:05 Duke: Maybe we ought to leave them down. That way we won't break them off! (Pause)
[On Apollo 15, Jim Irwin broke his antenna when he and Dave Scott forgot to stow it before he climbed back in the LM. In Houston, Flight is told that they need the antennas up because, if they bend over, the comm can deteriorate.]143:10:13 England: And John, if you're picking up a rock, could you get that...
143:10:15 Duke: Always thought it would work...(Stops to listen)
143:10:17 England: ...the vesicular basalt underneath the engine bell?
143:10:24 Young: Yep. Sure could do that.
[Fendell stops his pan with the MESA on the left side of the frame. Charlie is in view for a few seconds but then goes off-camera to the right.]143:10:27 Duke: Tony, that is a "double" Muley, that rock.
[Big Muley, the sample collected near the Rover at Plum crater is a 28x18x16 cm rock weighing 11.7 kilograms. A "double" Muley is clearly too big for John to collect, especially from under the spacecraft.]143:10:30 England: Uh-oh.
143:10:32 Duke: Come here, John. Let me get your antenna. (Pause) Well, I can't reach it. Why don't you get downslope and lean on the Rover.
[Fendell completes the pan and finds Charlie at the back of the Rover. John is at the right edge of the picture he is facing Charlie and is bent at the waist to get the top of his OPS into reach. He has his left hand on the top of the gate for stability.]Video Clip ( 2 min 50 sec 0.7 Mb RealVideo or 25 Mb MPEG )
143:10:43 Duke: There we go. Camera's on. This is a...Guess what. The antenna's up, and the comm is still the same. There we go.
[Charlie's cryptic comment about his camera is probably a reference to the fact that, with it on, he can't get very close to John.]143:10:59 England: And just forget that big rock for now. That's too big to handle.
[Young, from the 1972 Technical Debrief - "(During training) it had been easy for us to deploy our antennas when we were on the surface but, once we were in one-sixth gravity, the only way that I could reach up to deploy Charlie's antenna was to have him come over and grab hold of something like the ladder or the Rover and bend over so I could get my hand up to it. I just couldn't get a hand on it. That took a little more time because we had to move over to a new position. I don't think the communications would have been bad if we'd left the antennas stowed. I ended up breaking one because we forgot to re-stow it (at the end of an EVA). I'm not sure we shouldn't leave them stowed."]
[Charlie goes off-camera to the left and John heads toward the LM ladder.]
143:11:07 Young: Well, it's inaccessible; (laughing) it's underneath the engine cover.
143:11:11 England: Okay; fine.
143:11:12 Young: You want me to crawl under the LM?
143:11:13 England: No. That's all right.
143:11:15 Young: Okay. But there's probably another nice rock. I'm sure there's another good rock around here that I've been eyeing out my window I wanted to get anyway.
[Fendell pans left and finds Charlie at the LMP seat, just as he turns his checklist page to LMP-6.]143:11:25 Duke: Hey, John?
143:11:26 Young: Yes, Charlie.
143:11:27 Duke: I hate to tell you, but I need your camera for the (color pan)...Here, take mine with the black-and-white (film) and let me have yours for the pan.
143:11:35 Young: (Admonishing) Charlie.
[After taking the LMP Hasselblad off his RCU bracket, Charlie has run off-camera to the right to swap cameras with John. Fendell pans right to follow.]143:11:36 Duke: I'm sorry. Little out of sequence here. (Garbled) (Pause)
[Fendell finds John and Charlie beyond the Rover console.]143:11:50 Duke: (It's) like running together in the Sahara Desert. (Pause)
[The sequence of tasks had been designed, partly, to ensure that John and Charlie didn't get in each other's way. Consequently, they are used to working alone during this sequence of tasks and Charlie is amused that they - the only two people on the Moon - have bumped into each other.]143:11:58 Duke: Let me...(Pause) Okay; I got it. I got it.
143:12:04 Young: Got it?
143:12:05 Duke: Yeah.
143:12:06 Young: Okay. (Pause)
[Charlie goes off-camera to the left, going around the south side of the LM. John bobs down to pick an object - possibly a dropped bag - off the ground.]143:12:12 Duke: Okay. Hmm. "Happy birthday", it says.
[Charlie may be reading a note on his checklist, probably a reference to his intention to leave a medallion on the Moon to commemorate the 25th anniversary of the creation of the United States Air Force in 1947. The original flight plan had the start of EVA-2 at about 125 hours into the mission, or about 6 p.m. 21 April 1972, Central Standard Time. Charlie mentions the anniversary during the EVA-3 closeout at 170:19:51, having placed the medallion on the ground earlier and having taken AS16-117- 18844 and three other pictures to document it. See the discussion following 170:01:41.]143:12:21 Duke: (H)EDC (Hasselblad Electric Data Camera). Let's see; "pan quad III". Well, guess what? I'm on the wrong side (of the LM). (Pause)
[As is indicted in Figure 3.4-1 from the Apollo 16 Lunar Surface Procedures volume, Quad III is the northeast face of the LM. As Fendell pans left, Charlie comes into view, using a skipping stride as he goes clockwise around the spacecraft.]143:12:30 Duke: Ah, me. (Pause) Works better for me, Tony, if skip out here rather than (use another stride)...(Pause) If you want some of this blackish rock, John, a small one that's bag-able; there's a bunch right out here that look just like what I call that basalt. In fact, there's hundreds of them.
[Fendell has panned left until the plus-Y (north) and minus-Z (east) footpads are at the right side of the TV picture. As indicated in Figure 6-13 in the Preliminary Science Report, Charlie is about 60 feet north of the LM and, consequently, is not in sight. Fendell reverses direction.]143:13:08 Young: Yeah. They're out from that little impact crater we just landed beyond. And I want to get this nice white one right here.
143:13:18 Duke: Okay. The old pan...
143:13:21 England: And...
143:13:22 Duke: ...starts at f/11 at 250. Okay. Exactly 60 feet to the left, Tony!
Video Clip ( 3 min 39 sec 0.9 Mb RealVideo or 32 Mb MPEG )
143:13:36 England: Okay. (Pause)
[Fendell reaches the clockwise pan limit and finds John, who is visible beyond the console as he collects samples. Although most of our view is blocked by the console, it looks like he is just south of the LM shadow.]MP3 Audio Clip ( 11 min 50 sec )
143:13:46 Duke: The best pan. (Pause)
[Charlie's 4 o'clock pan consists of frames AS16-107- 17419 to 17440.]143:13:53 Duke: Boy, it sure looks different looking up-Sun. (Pause) You can still see those lineations in Stone Mountain, Tony. In fact, they're maybe a little bit more pronounced (with the Sun higher than it was during EVA-1).
[Frame 17419 is a down-Sun photo of the Solar Wind Collector (SWC) and 17431 shows some Rover tracks.]
[Frame 17435 is a good portrait of the LM, the MESA, the SEQ Bay, the Rover, and John beyond it.]
[Frames 17436, 17437, and 17438 also show John.]
[Frame 17440 shows the U.S. flag and the SWC.]
[Adam Bootle has assembled the portion of the pan showing the LM and Stone Mountain.]
[The f-stop settings used relative to the direction of the Sun are shown on decals mounted on the tops of the film magazines. 'HBW' is High-Speed Black-and-White and 'HCEX' is High-Speed Color Exterior.]
143:14:14 England: Okay. Do you feel like they're the same angle?
[The Sun has risen about 8 degrees in the sixteen hours since the end of EVA-1. If the pattern of lineations is a lighting effect, it would be expected to change as the Sun rises.]143:14:18 Duke: Yeah. Exactly the same angle. Down at the bottom (of Stone Mountain), there aren't any. They start in one place, that is, and it's a little ridge that's to the east of Cinco, down at the base; what we call the base here. There's two pretty predominant craters over there. Right there, there aren't any.
[John is taking a cross-Sun stereopair of "before" photos from the south of sample 60025. These are AS16-110- 17866 and 17867. Sample 60025 is the large rock at the center of both photos. Eric Nelson has created a red-blue anaglyph.]
[Fendell zooms in on John and manages to keep him in view as he bobs down to grab the sample in his right hand. He has a sample bag in his left hand. He came toward the sample from the north and, as he rises, he runs forward three or four steps to keep his balance. In the cross-Sun "after", AS16-110-17868, the imprints made by John's right knee and his right boot as he bobbed down to grab the sample are probably the ones to the right of center. The imprint of the sample is just to the left of center. The imprint John made with his right boot as he ran forward to regain his footing is probably the one at bottom right.]143:14:41 England: Okay. Why don't we catch that as you drive out...
[Tony is suggesting that Charlie wait to describe the lineations during the drive to Station 4.]143:14:43 Duke: But, otherwise, there are (lineations), all over the mountain. (Responding to Tony) Okay. I don't think we're going that far east, but...
143:14:49 England: Okay. Those extra pictures...
143:14:51 Duke: Okay, Tony. What is the other pic...(Stops to listen)
143:14:53 England: Right, of the Cosmic Ray experiment. So if you'll go over to that side, we'd like a cross-Sun, at f/11, 250(th of a second exposure) at 15 feet (focus).
143:15:05 Duke: Okay. Cross-Sun, f/11, 250 at 15.
[John has dropped the individual sample bag he was holding. During the following description, John is standing with his back to us, facing southwest so that he can get some sunlight on the rock.]143:15:08 Young: Okay, Houston. I just picked up this rock. It's a white rock - a very white rock - but it has a black glass layer on the back of it, or what appears to be black glass. A thick black glass. And it's about a hand-size specimen. I can't get it in a bag, but I'll get it anyway. And it has a lot of zap craters in it; and, lining the zap craters, are some white...whitish substance.
[Charlie comes into view briefly as he goes around to the south side of the LM to photograph the Cosmic Ray Experiment.]
[This is sample 60025, a 1.8 kg white-matrix breccia. This sample can be seen in AS16-113- 18301, a photo John took out his window before the post-landing rest period. The sample is near the fiducial one to the right and one below the center as indicated in a labeled detail.]143:15:38 England: Okay, John. Sounds good. And Charlie, we'd like an up-Sun of that cosmic ray, also. And the settings on that will be f/5.6.
[Zap craters - also known as zap pits - are small craters dug into the surface or rocks by small, high velocity impacts. Zap craters are often surrounded by and/or lined with glass created in the impact.]
143:15:46 Duke: Okay. Looking up-Sun...(Stops to listen) Okay. Do you know that thing's not even looking at the Sun, is that right? Is that what you want it to do?
[John takes the sample to the Rover and goes out of view as he goes toward the LMP seat.]143:15:55 England: That's right. We want it to look away from the Sun.
143:15:59 Duke: Okay; that's what it is. I don't think you're going to see much in this picture, but I'll take it. I guess it's just really gonna show you how it's sitting. Okay, that's done.
[Charlie's pictures are AS16-107- 17441 and 17442. Frame 17441 is a cross-Sun and shows the Cosmic Ray Experiment sitting in the minus-Y footpad. The fuel cask is beyond the strut on the southeast face of the Descent Stage. Note the various ALSEP and LRV deployment tapes in the area. Frame 17442 is an up-Sun and shows relatively little detail because of the shadows.]143:16:16 England: Okay; good show. And we'll have the UV after the PLSS load-up.
143:16:21 Duke: What else?
143:16:22 England: That's it, John...(correcting himself) Charlie.
[Fendell pans left and finds John as he raises the LMP seat and puts sample 60025 in the seat pan. Charlie is in the background, beyond the UV camera.]143:16:27 Duke: (Subvocal) Oh! (Pause) I'm tangled up in this spaghetti here.
[As he indicates in a moment, Charlie is talking about the ALSEP and LRV off-load cables which litter the area around the minus-Y (south) footpad. See Figure 3.4-1 in the Lunar Surface Procedures volume and AS16-107- 17441.]143:16:30 Young: Charlie, don't get too close to that (UV camera); watch out for the battery cable.
[Charlie goes off-camera to the right.]143:16:33 Duke: I see that; it's just this Rover deploy cable I was in. There. There, I'm okay. Okay, we're ready for the load-up, and I'll swap cameras with you. (Pause)
[We get a good view of John as he tries to get the camera off the bracket on the front of the RCU. It takes him several seconds to get it loose. At some point, John or Charlie gets an accidental picture of one of the fenders, AS16-110- 17869.]143:16:53 Duke: Put yours on your seat, John. Where'd those bags go that you had? You got them?
143:17:00 Young: I put them over here on my back...
[John finally gets the camera free and hands it across the Rover seats to Charlie, who is out of view next to the CDR seat.]143:17:02 Young: There you go, Charlie.
143:17:04 Duke: Just leave it there.
143:17:05 Young: Where?
Video Clip ( 2 min 59 sec 0.8 Mb RealVideo or 27 Mb MPEG )
143:17:06 Duke: There (on the CDR seat). Okay. Why don't you put those on my camera, and I'll put these on yours.
143:17:10 Young: Okay. (Pause)
[Previously, Charlie had put sample bag dispensers on both seats and he will put one on John's camera while John puts one on Charlie's camera.]143:17:15 Duke: I got two core tubes sitting up there, too. Don't let me forget those.
143:17:19 Young: Where? Up on the thing?
143:17:20 Duke: Yeah. Up on the Hand Tool Carrier.
143:17:22 Young: You want them in this SCB here...
143:17:24 Duke: No. They go back in here (on one of the bags on the gate.
143:17:27 Young: What are we gonna do with this SCB right here?
143:17:28 Duke: That one is going on my back. That's the one I emptied yesterday, (you see?)
143:17:33 Young: Okay. Fine. I'll get that.
[John goes around to the back of the Rover, carrying the SCB. Fendell follows and we watch John put the SCB on the left side of Charlie's PLSS. Because the TV is looking back across the seats and tool carrier, we don't seen much of what John's doing.]143:17:36 Duke: The other one...You're going to be chock full of core tubes today, babe. I'll tell you. This is core-tube-taking day. And a super SE(SC)...whatever. (Pause)
[The Special Environmental Sample Container is a vacuum sealed can they will use to bring a selected soil sample back to Earth for analysis of volatile components.]143:17:49 Duke: Okay. I'm ready for load-up, I guess.
143:17:51 Young: Okay. Hold still.
143:17:52 Duke: Excuse me.
143:17:53 Young: I'm loading you.
143:17:54 Duke: Excuse me. (Pause)
143:17:58 Young: I think that's what I'm doing. (Pause)
143:18:03 Duke: Ah, the old lunar surface. We've really kicked this stuff up, Tony, right around the lunar module where we walked. Where you don't have the footprints and the (Rover) tracks, it's very smooth, very white albedo...
143:18:18 Young: Charlie, could you bend over?
143:18:20 Duke: Yeah.
[Charlie bends at the waist about 30 degrees. John needs to fasten the bottom of the bag to the PLSS.]143:18:21 Duke: Very white albedo. Where we've kicked it up, it's about two shades grayer. It's a lot darker albedo. (Pause) And you know why I think that is, Tony? You look down-Sun, and it's not that way. You look up-Sun, and it is. I think it's the shadows that the Sun casts on the particles that have been disturbed that causes it to give a darker albedo.
143:18:55 England: Good observation. (Pause)
[The only problem with Charlie's hypothesis is that disturbed soil is darker only near the LM. As shown in photos taken from the Command Module, the soil around the LM is lighter than the normal surface. Although the precise mechanism that causes the surface to be more reflective isn't known, it is undoubtedly caused by the Descent Engine plume during the landing. When the astronauts disturb the surface near the LM, it returns to its normal color. Down-Sun photos taken on various missions show darkened soil in that direction. See, for example, AS17-14021355.]143:19:01 Young: Okay, Charlie. I got you.
143:19:03 Duke: Okay. Your turn. Man, you won't be able to carry this thing for the core tubes in it. (Pause) (Straining) Arrgh! Guess what?
[Charlie is struggling to open the latch that is holding an SCB on the back of the Rover.]143:19:12 Young: Open it.
143:19:13 Duke: I couldn't...I did. I couldn't get it off a minute ago. I mean I couldn't get it on a minute ago.
[Charlie is saying that he had trouble closing the SCB latch at the start of the EVA.]143:19:18 Duke: There we go.
[Charlie frees the SCB.]143:19:19 Young: Why don't you just lay those things on the seat. (Garbled) (Long Pause)
[Charlie goes to the right side of John's PLSS and John bends his knees slightly so Charlie can have an easier time getting the top of the bag attached.]143:19:40 Young: Houston, it's easier on the Moon to...There's a lot of trouble with the UV camera with the azimuth scale. It's easier to pick the camera up and re-level it by pushing it into the dirt than it is to change the azimuth settings. Every time you change an azimuth setting, you have to re-level it.
Video Clip ( 2 min 04 sec 0.5 Mb RealVideo or 18 Mb MPEG )
143:20:03 England: We copy that.
[John turns 30 or 40 degrees to his left. Charlie is working on the bottom SCB attachments.]143:20:05 Duke: Hold still, John. This thing (probably the Velcro patch that holds the loose end of the bottom strap that attaches to a mating patch sewn on the bottom of the PLSS) keeps coming off.
143:20:08 Young: In fact, the azimuth setting seems to be getting tighter and tighter. I don't understand that but, you know, that's what it seems to be doing. (Pause)
143:20:24 Duke: Dadgum thing! (Pause) You know, if there was just a patch of Velcro on these bags (pause) and one on your PLSS, you wouldn't have to worry with that strap.
143:20:49 Young: (To Houston) Let me give you an EMU status check while I'm standing here: 3.85 (psi), Min cooling, no flags, and I'm reading 84 percent (oxygen remaining).
143:21:05 England: Okay, we copy.
143:21:06 Young: (Does) that sound about right to you, Houston? Should I be that low this quick?
[As he reported at 142:09:32, John started the EVA with 92 percent oxygen. Charlie started with 94 percent. The EVA started at 142:40:00 and, in 40 minutes, John's oxygen reading has dropped from 92 percent to 84 percent. Extrapolation of that use rate would imply a 7 hour 40 minute capability. According to the Apollo 16 Mission Report, John started the EVA with 1.81 pounds of oxygen and consumed 1.22 pounds in 444 minutes and, in a typical 40 minutes, he used 11 percent of his initial charge. Consequently, he could be expected to have 89 percent of 92 percent - that is, 82 percent - remaining. Given uncertainties in gauge performance and expected variations in use rate with work load, his present reading of 84 is entirely reasonable.]143:21:15 England: We're working that.
143:21:16 Young: I mean, I'm reading about 80 percent. (Pause)
143:21:26 Duke: So am I, John.
143:21:28 Young: Oh, okay.
[Charlie finishes attaching John's SCB and John goes off-camera to the right. Charlie tilts his RCU with his right hand to get a better look at the flags and gauges on the top.]143:21:29 Duke: Okay. My flags are clear, Houston, and I've got 80...Oh, let's see. (Counting gauge marks) Seventy five; I've got about 83 percent. And I'm Min cooling; and pressure is at 3.85, and I'm very comfortable.
[Training photo KSC-72PC-140 gives us a good view of the top of John's RCU and Hasselblad.]
143:21:46 England: Okay. Good show.
[Charlie goes to the LMP seat.]143:21:47 Duke: Happy day. Okay; (reading LMP-6) "LRV prep. HEDC RCU; left seat to RCU". Pan, I got. "HEDC RCU to left seat." (Lost under Tony)
Video Clip ( 2 min 56 sec 0.8 Mb RealVideo or 26 Mb MPEG )
143:21:59 England: And Charlie, verify the Q mags on the DAC and that the DAC's running. Or it runs.
[Charlie gets the LMP camera off his seat and puts it on his RCU.]143:22:07 Duke: It's not running, but the Q mag is there. I...
143:22:11 England: Rog. We just wanted you to verify that the DAC was working.
143:22:16 Duke: Okay. Just a minute. (Pause)
[Charlie leans in so he can see the film advance indicator and briefly switches on the 16-mm camera.]143:22:22 Duke: Yep!
143:22:23 England: Good...
143:22:24 Duke: Believe it or not!
143:22:25 England: Good show. (Pause)
[Charlie tightens the map holder and then raises the LMP seat, probably so he can stow a spare SCB in the seat pan as per LMP-6.]143:22:33 Young: Okay. Going to reset the far UV again, one more time.
143:22:37 England: Okay. And your azimuth will be 276. (Pause)
143:22:48 Young: Okay; 276.
143:22:50 England: And the elevation, 14. (Pause)
[Charlie picks up sample 60025, the 1.8-kg rock John collected a few minutes earlier, and examines it. In the background, John goes to the UV camera.]143:23:03 Young: Okay, Houston; going to Reset. It worked. (Long Pause)
[Readers should note that zero azimuth on the UV camera is west, rather than north. Consequently, the new azimuth is just slightly west of south.]
[Charlie taps the rock several times against his seat back to knock some of the dust off so he can get a better look at the minerals.]143:23:36 Young: This must be the volcanic gases (target), because it's looking right at Stone Mountain. Is that what you want?
143:23:47 England: I'll find out, John; that 276 and 14, that is (the) target. (Long Pause)
[Before the flight, some of the geologists believed that Stone Mountain was a volcanic construct and, here, the UV camera is being pointed in the general direction of the Mountain to look for telltale emissions. As indicated in Figure 13-3 in the Preliminary Science Report, the field-of-view is about 20 degrees across.]143:24:04 Young: Okay; fine. (Pause) That's set, and she's working.
[Charlie puts the rock back in the LMP seat pan and closes the seat. He then adjusts the 16-mm camera.]
[Jones - "I'm a little surprised that you didn't say anything about that rock."]
[Duke - "I think there was probably just too much going on, and I just didn't want to take time to describe it."]
[John decides not to wait for an answer and returns to the Rover. Charlie turns to face the TV camera.]143:24:14 Duke: There's the big eye looking right at me! Boy, you can't get away with a thing around here.
143:24:18 England: Yeah, you're darned right.
143:24:19 Duke: Can't even turn around (without somebody watching). (Pause) Okay, John. Babe, I'm ready to go.
[Charlie consults his checklist one last time to make sure all the tasks have been done.]143:24:39 Young: Okay. How do you want...(Laughing) I get it, now.
[As indicated in his transmission at 143:24:57, John probably now understands Charlie's cryptic "Happy birthday" at 143:12:12.]
143:24:48 Young: Okay, Reset...Okay, (reading CDR-6) we're going to Mode switch to 1 on the LCRU, Houston.
143:24:52 England: Okay.
[TV off. They had planned to reach this point in the checklist at 46 minutes into the EVA. The EVA started at about 142:40:00 and, consequently, they are on schedule.]MP3 Audio Clip ( 0 min 34 sec )
143:24:57 Young: And the TV's going CCW (Counter Clockwise). "Happy birthday." Okay, Tony. Do you have any updates to Station 4 as far as numbers go?
[John is asking if there are any revisions to the bearing and range targets for Station 4. The planned traverse is shown on maps Descartes EVA-I, III; 1 of 3, Descartes EVA-II; 1 of 2, and Descartes EVA-II; 2 of 2. As Charlie mentions in a comment after 143:31:16, the map he actually used during the traverse was a larger-scale contour map showing the entire traverse. As indicated on that map, the first segment of the traverse was to have been a drive of 1.3 km on a heading of 173. Note that a zero Rover heading is north. In Tony's next transmission, Tony gives John an initial heading of 162 because they landed near CB.1/80.6 and not at CA.0/81.0 as planned.]143:25:20 England: Yeah. We'd like to head out in a heading of 162 degrees.
143:25:29 Duke: Okay; vise 172, okay?
143:25:34 Young: Okay. We're going to initialize the Nav right here by just going to Reset.
[Because the Rover Nav system worked superbly during EVA-1, John is proposing to skip the Nav alignment procedures on the LRV Operations Decal.]MP3 Audio Clip ( 3 min 01 sec )
143:25:42 Duke: I'll get System Reset. (Pause) Okay, I'm gonna climb in this beauty, I hope.
143:25:53 Young: That's how you want to do that, isn't it, Tony?
143:25:58 England: Say again, John?
143:26:03 Young: Okay. You don't need a Sun alignment or any of that stuff, do you?
143:26:11 England: Yes, we do, John. We need the Sun alignment, and go to Reset.
143:26:18 Young: Okay. (Long Pause)
143:26:31 England: And John, do you remember what the exact heading was where you were parked?
143:26:32 Duke: Oh, I'm in the machine!
143:26:37 Young: (Laughing) I'm parked there now. It was 358 or whatever it's reading on there.
143:26:43 England: Okay; fine.
143:26:44 Young: Don't you guys remember? I read it out to you.
143:26:46 England: All right. You just read north.
143:26:48 Young: You want to start from here, or do you want to turn...(Stops to listen) Okay.
143:26:56 Duke: We've got to get headed west for a Nav update, John.
143:26:59 Young: Okay; and that's what we're gonna do. (Pause) Still works!
143:27:10 England: Good show.
143:27:17 Duke: We're under way.
143:27:21 Young: Okay, do you want a Nav update from here now, or don't you?
143:27:24 England: Yes, we do, sir.
143:27:26 Duke: We've got to get it.
143:27:28 Young: Okay. Whoa, horse.
143:27:34 England: And while you're there, we'll need a complete LRV readout.
143:27:40 Young: Okay, Houston. It (meaning the Sun Shadow Device)'s reading 1 degree to the left, the Sun is. And we're heading of 268; bearing is 000; distance, 00; range 00, of course. And we are pitched 4 degrees down. (Pause as he flips the indicator to show the roll scale) And we are rolled 1 degree right - because Charlie's heavy today.
143:28:10 Duke: You rat! (Pause) That's why I didn't see that secondary from out here on the ground. You can't see the...The rocks are buried from...
143:28:21 Young: Look at the rocks around there, Charlie.
143:28:24 Duke: I know it.
143:28:26 Young: There's your basalts and things. Those are black. They're probably glass covered, don't you think?
143:28:31 Duke: They are. I picked up one out there. See where my footprints go?
143:28:35 England: Okay. Torque to 264, and could we have the rest of the numbers on the LRV?
143:28:42 Duke: Okay. Stand by. (Pause)
MP3 Audio Clip ( 2 min 40 sec )
143:28:48 Young: Okay. 264.
143:28:50 Duke: Okay, we got 114 and 114. Make that 108 and 108. Off-scale low, off-scale low on the Amps. Volts are 68, 68. Batteries are 82 and 100 and...Now they're up to 80 and 60...Oh, wait a minute. 80 and 95. Motors are off-scale low all of them.
143:29:21 Young: Hey, Hous...Houston. The LCRU covers are supposed to be 100 percent open at this point, ain't they?
143:29:28 England: That's correct.
143:29:29 Young: I'd better get off and open that rascal.
143:29:32 Duke: Okay. (Long Pause while John tries to unfasten his seatbelt) Want me to do it, John?
143:30:04 Young: Yeah. I guess you'd better, Charlie. I can't seem to unfasten this rascal again. (Pause) I got it. I got it.
143:30:12 Duke: I got it already. I'm gonna...I'm gonna do it. (Pause) Aow! (Pause)
143:30:35 Young: Watch it, Charlie.
143:30:37 Duke: Am I hitting the (high-gain) antenna?
143:30:38 Young: Yep.
143:30:39 Duke: I was afraid of that.
[Duke - "My PLSS antenna was getting tangled up in the high-gain antenna."]143:30:40 Young: Sticking your PLSS thing through it. (Both laugh; Pause)
143:30:51 Duke: (Probably getting ready to jump into his seat) Ah, here we go. Watch this. Oh, my pencil fell off, but that's okay (garbled).
143:30:59 Young: (Joking) Suppose you need that pencil.
143:31:01 Duke: Yeah. I can't even see the maps, much less the pencil.
[Jones - "So you had a pencil - or a pen - in the suit?"]143:31:06 Young: Looks like you're in pretty good shape.
[Duke - "Yeah. Right up here (on the left sleeve)."]
[Jones - "What sorts of things did they imagine you writing down?"]
[Duke - "I don't remember. (Laughing) Probably things like changes in the maps and those kind of things. You know, we'd write on the maps That's the only thing I can think of; but we had a pencil with us."]
[Jones - "I don't ever remember anybody using one."]
[Duke - "No. We didn't."]
[Jones - "Do you remember using one during training - marking maps and whatever?"]
[Duke - "Nope"]
[It was much easier to ask CapCom to take a note for later reference than to get the pencil out and write something down.]
143:31:08 Duke: We need a map holder like a windshield wiper. You can power up, I'm...Wait a minute. Okay. Hooked. Let's go.
143:31:16 Young: Okay. (Pause)
[Duke, from the 1972 Technical Debrief - "The map holder is worthless. You get in there with a 16-mm camera, your Hasselblad, and your knee. By the time you get in, you're pushing the map holder out of the way. It's sitting up there and you can't see the maps. What I ended up doing was taking one with the headings and topography on it - the 1/25,000 (for example, Figure 3.6.2-2 in the Lunar Surface Procedures volume) - and I wedged it between the 16-mm camera and the staff. That's a great place for the map because you can look up at it and see it. You can reach up and pull it out if you have to and just push it right back and wedge it in place. Unfortunately, our maps and photographs didn't look anything like the topography."]
[Young, from the 1972 Technical Debrief - "No resemblance to where we were."]
[Duke, from the 1972 Technical Debrief - "The Rover Nav as working so good; and we could see our landmarks. So, we had no trouble navigating. We really didn't need the maps; but, where they were stowed, they were useless."]
