LMP: Yes, I agree with Pete. Now, one interesting thing, when we were out at the Surveyor, that was sort of tan, my initial impression was that radi- ation or something had darkened the paint, but when you look at the chrome surface - the only · surfaces I saw that didn't look this way were the barer surfaces, by the way. But you look at the chrome surfaces of, for example, that battery box, and it had changed almost the same color, that light tan. Now, maybe if we had looked at it that first day and _t had been in sunlight, it wouldn't have looked like tan; it would have looked like gray, but it looked like tan - you'11 be able to get this, of course, because we've got the cameras with us - but when I rubbed the , Tape 12_/6 ' Page 921 box, it took of:'the light gray coloring; but it Just didn't dust off. I'm pretty sure that we didn't put it on with our LM, because it wasn't Just like dust that hangs aroand your house that's only been there a dc_y or twa. It was like dust that's collected on there for a long time and longer to have some effects on it, long enough so that it really becomes not a thick coating but a very cohesive coating. It was almost like a skin on there. You had to rub hard to get it off that battery box. When you did, there was a nice shiny chrome beneath it. It was kind of a strange thing, like a bunch of dust had blown on the box; and it had stood there long enough to really get hard.
CDR: But I think there's going to be enough parts that have not been touched by either our gloves or by the bag that the camera is in, that you'11 be able to get a good hack on that.
CC: Roger. I imagine also, we'11 get - -
CDR: Yes. Like the TV mirror.
CDR: Yes, the TV mirror has only my finger mark on it, and I'm sure that nothing else has touched any of the rest of +.hatTV mirror, and it was covered with this fine dust.
CDR: Also, in the same place with the mirror, Pete, although our mockup didn't look this way as I remember, there's a lot of electronics exposed in behind that mirror, ·that,of course, we never could possibly touch. It should have the same coating in there or something.
CDR: The other most important thing is the Surveyor was equally brown all the way around it; and had we covered it coming in, I think we'd have seen a directional pattern on the Surveyor, so I don't think, as a matter of fact, the way that dm_t flew when we landed, I don't think any of it landed within lO miles of where we landed. It Just took off.
LMP: I kind of agree. And even if it did, it wasn't \ going to fall in the crater; Just shoot right across it.
CDR: Yes, and the Surveyor was lower than we were.
LMP: Hey, did - I J_t thought of an interesting pos- sible point that somebody wants to do when they get with that camera - The geologists want to look at it when they get the camera before they give it to the scientists - is back in there behind that mirror where all the radiation could get in to - It couldn't get into as much as it could in, let's sey, the top. The camera got radiation all day long, because it would get it the minute the Sun came up and it'd get it all the way around to sunset. But inside that little hole where the mirror rotates, there's going to be parts in there, easily calculable, that got Just only a certain amount of Sun each individual day. Like, say, some parts would only get 10 per- cent of the Sun on the outside; some parts of the inside would get 50 percent, so if they're very careful with that mirrored surface in the back of the mirror and inside that little hollow place, they're liable to be able to get some index of how fast this stuff builds up and when it does.
CC: Roger. Were you able to notice any kind of ver- tical - -
CDR: They're going to have to be careful - -
CC: I thiz_kyou are going to want to have something thought through on that before that camera goes whistling off in the dist_lce. This is going to take a lot of fooling around with, before all that information would be lost.
CC: Yes, that's true, Al. We'11 have to be careful how we handle that. Did you notice any vertical gradient in the color on the Surveyor, as you might expect, if it w_s dust?
CDR: No, it wes pretty well uniform all the way over it.
UNKNOWN: LMP Pete brought out a point. It's strange, too. It was - all the way around; it all looked the same.
CDR: You see, we approached from the opposite side than we landed, and that was our first impression coming up on the opposite side was that it was brown. It didn't look brown the day before in the shadow, either; it looked white. And, of course, it was out in the sunlight by the time we got tD it on the second EVA.
CC: Okay, a question on the vesiculation of rocks. Did you really notice any or an appreciable m amount of vesiculation in any of the rocks you saw?
CDR: Not a one. That's what's funny. I guess Neil and Buzz brought some back, but we didn't see one rock anywhere with any of that type structure.
LMP: I agree with Pete. One time I reported I did, and then I looked at the rock when we finally picked it up, and it didn't look like it at all. It had a bunch of pits on it, but it didn't have any vesicules in it, and we were all doing some- thing else, and so I never really went back and corrected m_,self;but I've got to agree with Pete. I never sa__ any vesicular material at all.
CDR: I'm not convinced that we got too much different kind of rock material, to tell you the truth. Of course, I got fooled out there in the desert; and so anything that we saw that remotely re- sembled being different to our eye, we brought you a sample.
LMP: I don't think we - I think we got every - I think we got a sample of almost everything that was there. Everything that we saw that was different texture, in or the way it weathered, or where it was setting, or anything else that seemed unusual to us about the differences of rocks, we grabbed some of them; but, like Pete says, it's going to be interesting to see how many different things we did actually get.
CC: Pete and Al, were you able to notice any - which appeared to be boulder tracks on head crater or any of the other craters similar to the type of tracks you saw after you rolled that one rock down_
CDR: None. None that - Well, let me say thzs. I was - couldn't Without walking down to the crater, I tell what kind of a track the rock made that I rolled down there to start with. However, I think we have enough PAN photos that you can stereo in the craters that we went up to that if there any boulder tracks, you're going to be able to see them.
LMP: Yes, I think that's the best point right there. We took enough so you're going to find them. Now, I don't remember seeing any myself, but I think - I also don't remember specifically looking for them. Usually, when you see them, if you see anything special like that, you'11 remember it, but maybe there are some around and I didn't - Just even notice them.
CDR: All right, let me ask a question down there - when we were in orbit, we passed a particular area, and I'11 have to go back to the map and look, where there were three or four bright craters that had very, very dark gray material streaking down the sides of them, like landslides. Now, we were aware of many places by using the monocular, seeing landslide type or slides or slump in all the craters all around the whole Moon that we could see, but there were only these three or four craters that had very decided gray slumps or streaks or something. It almost gave you the impression that there had been a liquid spill or something. It was so different i'rom anything else. Has anybody raported that, or have you seen them in your photographs from Earth before?
CC: We'11 try and get you an answer to that, Pete.
CDR: That boulder track business got me to thinking about that. Go ahead with your question.
CDR: Let me say something else, too, and I can't re- t-l_ed member if I said it. You kn=w where we with Al Chinester [9] and the guys, before we went, about the main objectives of the geology I Tape 12&/lO I wasn't to go out and grab a few rocks and take mor- some pictures, but to try to understand the phology and the stratigraphy and what-have-you of the vicinity you were in. Look around and try to use your head along these lines. Well, I'11 tell you, there was less than 10 tim.es I stood in spots, including in the LM both times we were back in, and said, "Okay now, Bean, what can you do in that - can you fill that square? Is it possible to look at there and try and determine where this came from, which is first, which is second and all that?" And except for deciding which craters looked newer than others, which we know from ground observations, I was not able to see any special little clues like Me were, for example, over in Hawaii and we were when we were out at Meteor Crater and other places, that gave us that kind of clues. That whole area is Just - has been acted on by these meteoroids or something else so that all these features that are normally neat clues to you on Earth are not available for observation. I didn't find any way to fill that - those two big squares, you know; I never was able, when walking up to a crater, to determine when the normal ground stopped and the ejects started except on the difference in slope or the fact that it got a little bit more powdery under my feet, and that's not a very good index. We never saw anything of a different color or a different amount of rocks or anything else, except the times that Pete and I kept kicking up that very light gray as opposed to the more dark cement-gray material. There's Just no contrast to look at.
CDR: I think even a trained geologist would have trouble doing a whole lot of field geology that way on the Moon. I think what you're going to have to do is pick your traverses like we did and Just sort of select at a regular interval as you go along and then come back and analyze the stuff to find out differences. I've kind of got the idea that a lot of it is the s_m_ and the only difference being its relative age to one another by being blasted by a meteor coming in and getting thrown out al different times. Don't you think that, Al? 124/11 Tspe
LMP: I think that. I think one of the things you're going to want to up, too, is you're going to want to up the number of core tubes so you can get down in these areas you are interested in and find out what's going on under there, because it's covered with this layer, and there Just ain't no way to figure it out. I know, thinking back - like I say, before the EVA, during the EVA, and after- wards, we talked about it and thought about trying to get the big picture, trying to be more than and rock collectors picture takers; and, believe me, we worked at it, and I think from our training we were pretty doggoned good at getting that sort of thing in training, not just grabbing a few rocks, but trying to evaluate the things that we want to evaluate. But it Just was difficult to do because the clues Just aren't right laying there on the surface. It's got this big blanket of all- beat-up soil over _very single thing. I think maybe you want to get a better trenching tool. Pete, the trenching tool we b=d was Just that shovel and he could only go down about 8 inches without falling on his head. Now, if you don't want to get a lot of core tubes but you want to ") see what's going on maybe we need some sort of better trenching tool so a guy can lean over and trench down 6 or 8 inches or, at least as far as the ground is soft, and then take a look at what's underneath it.
CDR: We were really hindered in the fact that we could 'not bend over. It wasn't as apparent in our training as it was up there because, in your training when you weigh 285 pounds there in the building, and you've got all the stuff on your back, it's fairly easy to sort of scrunch down or lean quite a bit. You can't do that up there on the Moon, and like A1 Just said, and I'm short and low to the ground to begin with, that somebody that's taller than I am is going to have a difficult time with the same length tools trenching as deep as I did. Because you Just can't get over. And we've really - we got a whole bunch of ideas and we're going to, in the 5 days there in the MQF, we'11 put all this down on paper on what we think we could do to pass on some suggestions to improve the tools that we have right now, to do a little better Job. )
LMP: Yes, I think those tools can really be worked over; they seemed pretty good before we left, but once we got up there and started working with them, in that one-sixth g, like Pete says, you can't always do the same things; you're leaning in a different way, and things are a little dif- ferent. I th_nk we Lhought about it enough and observed it enough that we callcome back and give some pretty good suggestions for tool improvement and equipment improvement along those lines that'11 help the next guys get more rocks, and better rocks, and faster, and trench deeper, and do more core tubes, or whatever else they want to do. Hey, tell them they can start fixing that doggoned hammer.
CC: Okay. Thanks for your comments.
CDR: Yes. We concluded that everything is too delicate to start with; the extension handle was about wiped out by the time A1 got done driving that double core tube.
LMP: Yes. Even though you're light up there, every- a h,mmer swinging, or if you get moving, and want to stop, you could st_ll put some pretty good loads on some equipment.
CC: Okay, Pete and Al. That's it for the questions. thanks very much. Could you give us a reading off the 02 pressure gage on the REPRESS pack ?.
CDR: Yes. One more thing, that we did - getting back to this crater morphology and all that business; when we looked at those craters, we tried to do that, too, because we could see bedrock, or what we thought was bedrock, on the outside, we said, "Great! We're going to look in those craters." This is what we said before we even got out. "We're going to look in those craters and we're going to see a deep contact between the r_golith and the bedrock, and we're going down a little bit further and here's going to be something else; we really got it knocked." We looked in those craters and what it looks like is Just like the surface except there is a few rocks that seem to be resting on the wall and resting in the bottom. Now, if you went down there and dusted away all that material, I don't know how much there is ther e, maybe you would find a contact between the Tape ]24/13 Page 92_ regolith and the bedrock; _ow, you know, you really couldn't see it. Now, maybe you could infer it from the pictures we took and wh;_t we discussed. and ti:ere, Us_:lly, _t was showing here particu- larly on that very last crater. But that's go- ing to take some work; it's Just not like looking at a crater on Earth.
LMP: I think the - the fact that it h_s this makes geology up there as difficult, if not more dif- ficult, as it is on the Earth, because you have trees and grass and all kinds of things like that that hide a lot of the Earth's geology· So, I think you're in the same box up there. · .. What do you want? The REPRESS package is 850 psi.
CDR: Another thing that has been concerning me a little bit - you know we keep talking about going to all these neat places like Hyginus Rille and all that stuff, because we are going to stand on the slue right below the rille and we're going to look up on that big high side and right there is going to be the history of the Moon, sort of like the Grand Canyon gives us such a great one of the Earth. Well, I'11 tell you, if the sides of that place are anything like the sides of craters, or the sides of the Surveyor, you're going to look up there and you're going to see a bunch of dust Just like you see on the surface, unless - you know - I could be easily wrong, we haven't been there, but - but we Just didn't see any places, no matter what the slope, that didn't have all this material all over it.
CC: 12, Houston. I'm looking back at all the burns and result of the VC counter. It looks as though the thing's working pretty well from what we can determine. We've looked back at midcourse 2, LOI l, LOI 2, and the lunar orbit plane change, both of them, and TEI; and it looks as though it's - predicted and the crew readout are doing pretty well. They're in pretty close agreement·
CMP: Okay, Ed. What you say - what you say is gen- erally true, now and the reason I say that is because those burns - these things are being held up until about 20 seconds or so before burn time. I measured the PIPA bias exactly one time, and it came out to be 1.4 feet per second in 1 minute which is really power; and there's no question about that. And the only other thing, the other indication I've got is that on the DELTA-V test ycu- 586.8 in 10 seconds on the DELTA-V test, you always come up with minus 18.1, which seems to be a little hig_r that we'd expect to see, although we're still perfectly within tolerance. I see nothing wrong with it. During the RCS burn, the bunl took a little bit of time to do and ko trim out; and, during that time, the PIPA bias or the bias or the four other bias in the E_._ mas actually almost as high as my ability to trim, so that's w_y you got such an errcueous reading on that. That had a little something to do with the separation from the booster at the TLI also, but I'11 talk about that later.
CC: Yes. Those things still up there within toler- ance, however, Dick.
CMP: Oh, that's correct. Yes. I recognized that. I Just want you to know that that's what we've got, and I guess that's Just real world.
CDR: Hey, one last comment, there, Houston. How about telling old Uel Clanton that we both thought we were in Kapoho, too, when we were on that Moon, and we gave him about the - about the same type of information that we gave him at Kapoho, as far as it was visible.
CC: Roger, Al; will do.
CC: Say, if it's possible for you to see out of the rendezvous window to get a good shot at the Moon, we'd like to get some more small-scale, high-latitude photogr&p'ns, and this would be at your convenience. If you think you can do it, give us a call, and we'11 give you some procedures. Page 930 i)
UNKNOWN: Okay. Now we Just took some about 2 hours ago, some 250-millimeter of the Moon _'hich, of course, are full frame. Would you care for some now and what lens would you like?
CC: It sounds as though you pretty well outguessed us. The Hasselblad with the 250-millimeter lens, black-and-white film, 5.6, 1/250th and, of course, at infinity, and if you'd take two or three photos and repeat approximately at 30-minute intervals for i hour.
CDR: Okay. We'11 - Tell m_ the f-stop again. That's the only thing I didn't hear. Okay. We got it. I 'm sorry
CC: 5.6.
LMP: Go ahead, Ed.
CC: Apollo 12, Houston. Are you observing any vari- ) ation in the antenna position at the present time?
LMP: No. I've been sort of watching it, Ed. The only thing I've noticed this whole time is every once in a while the yaw rill Just wiggle one time, Just a smidge, and that's the only thing I've seen. Otherwise, it's been steady as a rock.
CC: Okay. We Just picked up a little variation in your signal s%rength down here.
LMP: Okay, now wait a minute here, that Just made a liar out of me, because it's Just starting to do it up here. With the signal strength varying; and it's doing it in yaw .... in yaw.
CC: Roger. We're Just starting to pick that up down here. DSE, ON, please.
LMP: DSE, ON. Roger.
LMP: Okay, now the RECORDER is ON and we're in LOW. Do you want us to go to HIGH BIT RATE?
CC: Affirmative. HIGH BIT RATE. 12_/16 Tape STOP.
CC: Apollo 12, TAPE RECORDER to
CDR: Okay, that's done, Ed.
CC: Thank you, 12. It looks as though it's settled down. Let's just keep an eye on it.
UNKNOWN: DSE to FORWARD.
CDR: Yes, we got it.
CMP: Roger. Let me give you the angles on the GDC at this time.
CMP: Okay. Roll, 072.25; pitch is 352._; yaw is 081.55.
CC: Roger, Dick. Copy 072.25, 352.4, 081.55. Thank you.
CMP: Roger. I'd like to get the other one later or before we leave this attitude.
CDR: It looks like what the antenna's done now is driven to some position other that OPTIMUM and it's Just sitting there.
CC: 12, would you go to WIDE BEAM width?
CDR: Roger. WIDE BEAM width.
CC: Apollo 12, DSE to OFF.
CDR: Roger. It's OFF. antenna hoxding
CC: Apollo 12, is the steady at the present time? J
CDR: As best as I cab tell it is, Ed. It's moved a little bit from where it, was a little while ago, but it's not wobbling like it was doing the other day.
UNKNOWN: that back. It may be wobbling Just a little teeny tiny bit. I can see Just a very slight oscillation in signal strength and maybe - of course, our gage is not to ... for being so inclined - It looks like it might be oscillating a degree or so.
CDR: And that's normally in yaw.
CC: Roger. Yaw.
CDR: The other day when we were in the I24 and Dick was having that trouble, it was oscillating in both axes, pitch and yaw.
CC: For your next P23 at 195, we have another cali- bration star which I think will work out a little bit better for you when you're ready to copy.
CC: That's at star 24, Gienah, and the attitude is roll, 092; pitch, 329; yaw, 0. And that should give you a pretty _mall angle difference between the next attitude you'11 be going to.
CDR: Okay, thank you. Appreciate it.
CMP: This ought to be a very interesting one, Ed, because I noticed on the other series - The first series of P23 that Gienah was pretty dim in the normal optics mode, but I'11 be interested to see if I can see the star through the landmark line of sight and I'd like to try it. It sounds good to me.
CC: Roger, Dick. END OF L'APE
CC: Apollo 12, Houston. Would you put the DSE at FORWARD, please?
CC: 12, could we have the TRACK mode to NARROW?
CMP: You got it, Ed.
CC: Roger, Dick. I'd like to trade you.
CMP: Not yet, Ed; not yet. Two more days and you can.
CC: Apollo 12, Houston. Could we have secondary electronics?
CC: Apollo 12, Houston. Would you give us secondary transponder and pause at the center position?
CC: Apollo 12, Houston. Could you give us your onboard readouts of the high gain antenna angles, pitch and yaw?
LMP: Roger. Pitch is about a minus 20 and yaw is about 190.
CC: Apollo 12, Houston. Would you select WIDE BEAM width, and then go to MANUAL, and select pitch, 60; yaw, 240? That's a pitch of minus 60.
CC: Apollo 12, Houston. Would you give us AUTO REACQ - AUTO REACQ?
CMP: Okay. You got it, E3uston.
CC: Roger. Thank you. We apparently dropped off there when you went to MA_AL and that was pitch, minus 60; yaw, 240.
CC: Apollo 12, Houston. Would you give us the pitch and yaw readings on the high gain antenna?
CMP: Roger. it lcoks like minus about 22 and 1 - I guess about 190.
CC: Roger, 12. And also, if you would, the GDC angles.
CMP: Okay. Stand by. I'm going to work on those at ·.. couples.
CMP: Okay, Ed. Here's the best i could get here for you: roll is 093.1, pitch is 339.25, yaw is 086._.
CC: Roger. 093.1, 339.25, and 086._.
CC: Okay. We're finished up with the ... test on the S-band, and we'd like to go to LOW BIT RATE. FORWARD, The S-band AUX to OFF and TAPE RECORDER, to OFF, and we will be staying in the WIDE BEAM width.
CDR: And you want us to stay on the secondary trans- ponder?
CMP: What's the test look like, Ed?
CC: Stand by, and we'11 get a s.mm_ry of that for you. _d, Dick, before you go over to the P23's, you want them - They want to manually maneuver away from gimbal lock.
CMP: Okay. I got a whole hour before that P23. Is there anything you want us to do, or any particu- lar attitude to be in?
CMP: If not, we'11 look at the Earth for a while. )
CC: Dick, at this time, you can go on over and do the P23's; the angles we gave you are still good. 125/3 Tape And then at - When you finish up with that, you can go back to PTC -
CMP: Okay. You want us to do P23's; go ahead and do them an hour early, is that correct?
CMP: Okay, fi_e. Here we go.
CMP: Roger. Here is the inner vector I have in there for Venus at this particular title. Okay? Knowing you're an hour early.
CC: That's affirm, Dick. It's good.
CMP: Roger, I want to make sure you're getting all this.
CC: Dick, we're watching it all.
CMP: You were so quiet, I wasn't sure you were getting it.
CC: Watching some good working action.
CC: On that last lock, I thin_ I took _t past your horizon mark .... is a little bit too far, but i'11 take it anyway.
CC: 12, say again.
CMP: I think that last hack, Don, was just a little bit into the Earth too far. It won't be on the horizon; that's okay.
CC: Go, 12. 125/k Tape 936 Page
CMP: Guess what! I don't have a star.
CC: Apollo 12, say again, please.
CMP: I said I don't have a star.
CC: Dick, you're going to have to try that once a_ain. _e're breaking up in communicatloa_, and we don't read you down here.
CMP: Roger, how do you hear me?
CC: Still breaking up, but probably readable. Try it.
CMP: Okay, I do nct have a star for star number 56. There is no 6N star 20h.
CMP: Tell the boys in the backroom I don't have a star for this particular one in the field of view. I can't see it.
CC: Roger; we'11 work on it. CC Dick, part of that test, we wanted to make sure whether or not you could not see the star because of light shafting. Was that the case? CMP Well, it's light out there. I don't necessarily see any light shafting, but I sure can't see the star in the field of view.
CC: Roger. Then - -
CMP: I don't know why, or what the reason for it is.
CC: Okay, the nay star then is star 24 and the Earth's far horizon.
CC: We'd like you to dump the waste water down to zero before you go into the PTC, then we won't have to disturb that later, if you would for us.
CMP: Okay stand by, I want to get this BIAS - ... in BIAS yet.
CC: Sure, anytime before you set up PTC.
CMP: Don, this is Dick again. Where do you want to take the waste water down to before PTC? an
CC: Take it clear down to zero, then you'11 have undisturbed night 's sleep.
CMP: Okay, you're not worried about that bladder all the way down to zero, huh?
CMP: Don, I was curious on that 6N when they use star 204. How close is that to the Sun?
CC: We're looking it up for you, Dick. Dick, that was 20 degrees; 20.
CMP: It seems like I could have - should have been able to see it, then, huh?
CC: It's in that area where it's kind of marginal, Dick, and we were kind of interested whether you could or could not see it.
CMP: Okay, well, I sure looked all over in there and I couldn't see any star in the field of vi_.
CMP: In fact, it surprised me; I thought I was going blind.
CC: Maybe that star didn't get turned on today.
CMP: Don, I was going to accuse you of the w_'ong ... vectors and all kinds of things like that, but I thought I better not.
CMP: Don, do you want to take an E-memory dump at this time?
CC: Give us just 1 minute to set up, Dick..
CMP: Okay. this last - this last set of stars - the airglow / is starting to - to show up, and I'm starting to use the top part of the airglow for a visible horizon.
CMP: That first set it was not the ease, or at least I couldn't tell that there was any airglow there anywhere ... Just used the high part of the horizon.
CC: Dick, we show you down to zero on waste water now. AIR-TO-GROUND 126/1 Tape
CC: Apollo 12, we're ready for the E-MOD dump.
CMP: Okay. It's coming at you.
CC: Roger. Also, Dick, how well could you see Venus, the first star you did, and the fifth star, 1637 Were those clearly visible?
CMP: That's affirmative. No problem with the stars at all. Venus - Venus, of course, looked like about four of them put together.
CC: Roger. Very good. Thank you - -
CMP: Actually, it's - It's a very easy planet to use for the simple reason that you can take the hori- zon and strip the image of Venus so that you get m-wk a pretty good off of it.
CMP: And the rest - the rest of them, the stars are so &_m that you really can't do that. All you can do is get the star down to the horizon, but with Venus, you can actually split the planet with the horizon.
CMP: Houston, let me know when you're through with that E-memory dump. I want to take a look at 83 and see what I did to my AUTO state vector.
CC: Roger. We're through with the E-MOD dump now, and when you look at 83, would you also look at NOUN 34, too, so we c_]1 check that one? Okay. VERB 83, NOUN 54.
CMP: Want it now? Okay.
UNKNOWN: Okay. NOUN 54 is 6.24 miles and zero velocity.
CMP: How does it look down there?
CC: Looks fine.
CMP: I'11 do a P37 and see what it looks like.
CC: Apollo 12, for your information, at the end of the second quarter, Michigan leads Ohio State 21 to 12.
CDR: Okay. Sts_-tling,huh?
CC: There's s_ill a little more to go.
CMP: Hey, Don, ask them if they - -
CMP: Okay, ask FAO if he knows a secret hiding place for P30 PAD's in the spacecraft.
CC: We're not sure you're cleared for that information.
CMP: Well, I'd sure like to be because we ran out of them 2 days ago.
CC: He doesn't know of any other place - any special place to look. We'11 - We'11 ask around in the back room, but first quick _-tess is he doesn't knov.
CMP: Well, I don't think there are any. So we've been manufacturing them for 2 days.
CC: Roger. We'11 research it some more.
CMP: Some of these guys didn't have anything to do anyhow.
CC: We'11 try to keep down the number of midcourses so you won't need any more.
CMP: That 's good; that 's good.
CC: Dick, would you confirm that you terminated the water dump?
CMP: That's affirmative. We terminated when you hollered at us.
CC: Fine. Thank you.
CC: Why, doesn't it look like it?
CC: We can't tell for several hours, and they were worried. Page 9_i
CMP: &ay. I'11 check again, but I know we did.
CC: No sweat, if you did it.
CMP: Then rest assured; it's terminated.
CC: Apollo 12, Houston. According to all our infor- mation down here, the only P30 PAD's you have are in that CMS - CSM update book, and there should be only 12 of them counting both sides of the pages.
CMP: Yes. Okay. That's fine. We ran out; that's all. All right. We Just thought maybe there were more around here some place else.
CC: Not to our knowledge.
CMP: We've already scrounged a couple P30 PAD's out of some contingency books, so when they think of those, why, forget passing it up, because we al- ready got them.
CC: Dick, we rechecked your P37 solution down here in our computers, and it agrees exactly.
CMP: Very gond.
CMP: Don, if you think we're stable enough and it looks like we're under control down there, we're going to go ahead and start PTC.
CC: We suggest you let your rates damp out a little bit more.
CMP: Thet's a suggestion I'11 gladly follow.
CMP: I guess the reason they're there, is we're still moving around a bit. Everybody's cleaning up and shaving. We're through dumping _ater and every- thing else overboard so we probably can try and Page 942 '_ get it started. Maybe we better remain a little more cngm inside here.
CC: Apollo 12.
CC: Roger. The rates look okay to start up on PTC. We'd like you to turn off the high gain, - turn the POWER, OFF; and start with 05tNIBravo as you start the PTC.
CMP: Okay. HIGH GAIN POWER, OFF; and 0_._NIBravo for PTC.
CMP: And we're on OMNI Bravo.
CC: Tb_nk you. !
LMP: Go ahead, Houston; Apollo 12.
CC: Roger. We suspect that after the evaporator temperature is stabilized here _n your PTC ma- neuver, the temperature in the cabin m_,Vget a little warm for you, so we want you to evaluate what that feels like before you get ready to settle down for the night, and we mmy either have to adjust the mixing ratio colder or go · back to AUTO, at your choice.
LMP: Ok_. Last night it was fairly cold PTC, so I feel we're Just going to - if it gets too warm this way, when we finally get in the proper atti- tude, well, I guess we'11 Just have to turn iL dowa a smidgeon.
CC: Roger. It'11 probably take about another hour tO -- --
CC: It's got to be somewhere between - -
CC: It'11 take about another hour probably to sta- _) bilize. Page 9h3
LMP: Okay. I Just - Okay.
CC: Pete, some time this evening, if you've got time, we've got some geology questions down here that we would lik_ to send up to you. And, when you ws.ut to discuss the_i, we'11 - We'11 pipe them up you, to if that's all right with you.
CDR: Are these different from the geology questions we got about 3 or 4 hours ago? We're glad to do it.
CC: That is affirmative. It's really a continuation of the same kind of material, but we've got eight specific questions.
CDR: Okay. Why don't we start in about - about 10 min- utes? We're cleaning up from a meal and we'11 be ready to go in lO minutes.
CC: Fine, or any time is fine. Thank you. TRA/{SCRIPTION 127/1 Tape i)
CC: Go, 1_.
CDR: Roger. We're ready for your questions.
CC: Okay. Let's start with two quick ones on the Surveyor work. The first one is, are you bring- ing back any glass from the Surveyor ther_c_l switehplate?
CDR: No. The glass apparently, which we didn't know, was bonded onto metal; and then, the metal, in turn, was bonded onbo the little standoff things that held it off the top of the box. We tried to get it, and everybody had told us back there that it was going to have separated from its bonding, and it had not. It was in great shape. It was bonded to the metal just perfect. We beat on it, smashed, and bent, but all we did was break it into little teeney, tiny pieces. Shattered it, actually is what happened, and it Just remained fastened, very tenaciously to the metal it was bonded to. That was that. We Just couldn't get it.
CC: Roger. Whoever made that bonding material will appreciate that testimonial. Okay, on the second one, did you get any soil samples from the Surveyor trenching area other than the mate- rial that may be with the scoop itself_
CDR: The scoop itself has some material left in it, I believe, or - it'11 be in that bag, and that'11 be it.
CC: Okay. Roger. Next question now goes to the geology area, and the question's - Well, I'11 start out here. Did you ever climb one of those mounds, and what more description can you give us of the mounds, and particularly was there any apparent orientation or elongation to the mounds? Also, anything about vent holes?
CDR: Okay. Now, the mounds weren't that big that you would climb one. You could Just stand and look at it. There were two of them. One was bigger than the other; and, no, they didn't have any vent holes. Their orientation - both of them, appeared to be in an east-west direction. Sort _. of - Let's say you had a strip that was about a foot wide, that you Just bent it and made a little triangular thing out of it. The mounds looked something like that, and we sampled all around one mound. Brought back stuff from it - material; excuse me, Uehl Clanton. That's about all I can say for them. They didn't ... I guess you're - I think you're hunting around for any- thing volcanic in nature, and they didn't appear to, to us anyhow. They appeared n_ore like a big glob of something that had been pitched into that particular area, either by the craters that were formed nearby or something else further away. We looked around for all evidences of vent holes or anything coming out of it that might be scat- tered around, you know. Let's _ay, rocks from it itself or some ejected pyroclastics around on the ground might be near it. We couldn't find wondering any of those either. I was kind of at _he time why you didn't ask u_ to give a core tube through it, but you didn't.
CC: Roger. Thanks. Next, if there's no more in that one, the next one is whether or not ycu noticed any preferential distribution of the glass beads and the glassy material?
CDR: Generally speaking, it was all over the place in the bottom of even the smallest little craters that we came across. But we found it wherever we went, and no more in one place than in another. I think that we have three or four samples of glass that looked the same that were taken from different places, and they should be documented. One of them isn't, but I remember where we got it.
CC: Roger. I'm not sure I understand. Did you mean that they - the glass beads were in the bottoms of all craters or that they were on the tops of the level surfaces as well as in the bottoms of the craters?
LMP: That's right. When we walked around on the level surface, if you Just look down and look even halfway, you'd find beads here and there. Now, you didn't find a lot of big ones. You'd run across big ones every once and a while, big ones being about a quarter to three-eighths of an inch in size. If we came upon those, we would see them, but generally there were a lot of little ones Tape i27/3 Page 9_6 [) around. Now, if you looked down into the small craters, I'm thinking of the craters 3 or 4 foot in diameter, maybe a foot deep, it didn't look like they were made with very big objects; you would usually find glass beads at the bottom and you would usually find glass-covered rocks, and that was surprising to us because we had always imagined that these beads Just came from very - from the more - the iorger craters, up to 8 or 9 or 10 feet, but this didn't seem to be the case.
CDR: Also, if I remember, we have a rock which is some 2 inches or so in size that is spattered with glass, and we brought it back for that reason. They are not beads; it's Just a big splatter - -
CC: Apollo, break, break. We have lost antenna for a moment.
CC: Apollo, break, break. We have lost C0_ for a moment.
CC: Apollo 12, Houston. Do you read us?
CC: Apollo 12, Houston. Do you read? j
LMP: Roger. We apparently lost your antenna for a while. We are ready to go again.
CC: Roger. We switch antennas there. Al, the last thing we heard you saying was that in some of the small craters there were glass-covered rocks. Would you repeat anything after that?
LMP: Roger. Did you hear Pete's description?
LMP: Okay. Right. I was saying that even the craters up to as little a_ 3 or 4 feet in diameter, i foot deep, the ones that didn't look to me like they were made by either very heavy particles, or very fast particles, you could usually look around in the bottom of them and see glass-covered small rocks, in a number of them. We took some pic- tures and documented them real well, and then I'11 let Pete - let me say the rest. Also, one time when we were walking around outside a big crater, we saw a rock about 3 inches in diamuter, I guess, scmewhere around in that neighborhood; and it wzs almost completely covered with this glass. And the glass looks the same as the glass you see in closeup stereopietures that Nell brought back, that he took pictures of, down in small craters. So, this will be a nice sample for somebody to look over.
CC: Very good. Okay. Next time - next question is - Can you give us some more detail on the material melt-d that appeared to be in the bottom of bench crater? Did this Just cover the central peak or did it appear more extensively located - spread around down there?
CDR: It appeared to be - to look - a little bit lava- like in nature but I don't mean to imply that I thought the crater was volcanic in origin. It looked more to me like we were seeing the effects of some high-speed impact 8_ld - causing some melting of material down there. I wish that we could have gone down in that crater and gotten a sample, but it was too steep and too rugged for us to attempt it, and, therefore, we did take some partial PAN stereo of the whole crater for you and we tried to get material from the top but nothing from the top resembled the material in the bottom.
LMP: I think the reason Pete said that to begin with is our experience over in Hawaii ia some of those chains of craters or those lines of - I can't think of the exact word now - but where the lava comes out in long cracks, zones of weakness; it Just sort of bubbles out and spatters one on top itself and ends up making sort of knobby-looking mounds of basalt. Well, from the top of the crater, all this stuff looked like knobby _!it_l_ mounds that were sort of like ... zones - the material you usually see around ... zones and that's why he is trying to stay - neither of us think of it as a volcanic material, but it had that sort of melted knobby effect. We got a lot of pictures of it, though.
CC: Roger. On the northwest side of head crater, you talked about a rock that you kicked over, and you mentioned that the bottom was different from the top and we are not sure Just in what way it was different. Remember that one?
CDR: Well, yes - I remember it and it wasn't different in - I think maybe - I should maybe have clari- fied it then because it wasn't that big a deal - Page 948 ) I guess it was the first time that when we kicked over a rock, it was two different colors, you know. Before you'd kick over a rock and it looks Just lik_ the top is the bottom. This one, it looked a litble bit lighter gray and the reason vas) after I thought about it, was because we were marching around in that same area where we noticed that there were two different types of soil. The soil that was the topsoil for Just a thin layer on the top of an eighth oz' an inch or something, and then below that was the thin gray layer and that - what was causing the rock to appear white, in this case, instead of gray like the top was the fact that it had been in this light soil down beneath the surface. So, I don't think it's a big thing.
CC: Roger. Let me give you the last two questions, so you can cover them together. The first one is, are there any special or unusual feat_lres that you remember, thinking back on it now, that you didn't have time to describe? And the other thing is, can you sort of recap the traverse along each leg and recall what you think was the feature significant that you saw at each of the stations where you stopped?
CDR: Wait i while we discuss it a second. Sure.
CDR: I think we pretty well talked about everything that we saw that attracted our attention. We can't think of anything right now that we saw that we didn't mention to you sometime or another, either during the EVA's or after. Al's only com- ment, which he already said he talked about this morning, was the fact that the color did change with the Sun angle between the first day and the second day. As far as the traverse goes, I guess that the most significant thing - There was noth- ing unusual at head crater other than the - the fact that we found that - I guess, that head crater was where we first saw the difference in soil below the ground and above the ground. The next most significant thine I think, is as we did go over to sharp crater, - Yes - no, no, head crater is not where we saw it; no, the crater - What was the name of the crater that we saw the material we J,,st discussed? Was it - That was bench crater, right? ') 127/6 Tape
CC: Say again on that, 12.
CDR: Wasn't the rJame of the crater - our second stop on the traverse was bench crater, is that correct?
CDR: Okay. The - I'_ get our boo ks out except they're so dirty with dust, and we've had a h_ck of a time getting rid of the dust in the command module, I don't want to do that.
CC: No, don't do that.
CDR: The - We discussed the difference in texture of the rocks at the bottom of that crater, i guess the next most significant thing was that some- where between bench crater and sharp crater, we obviously ran over what must be a contact in that the ground very definitely changed to a softer, finer dust. We sank in deeper out there not only right at sharp crater but leading up to it. ;;ow, we both found it very difficult to ever wsl_ slowly. We always went at a lope where ever we went; that just seemed the natural way to go. So, A1 sort of spotted it first watching me run because he was behind and he could tell that - I guess I was kicking up more dust. Is that right, Al? had started running on a different kind of ground, or dragging his feet, one. It turned out it was different kind of ground.
CDR: And I guess that's the most significant thing over there on thaL part of the traverse. From there, we're not sure that we ever did get to have to look at the maps again and figure out exactly where halo crater was because there were have been halo crater, all together; and it wasn't apparent in looking at the little map that we had which was colored at that spot, whether there had a very difficult time locating it. We suspect that we were not in halo crater but if we weren't, significant thing was the fact that from halo 127/7 Tape Pace 950 crater, or coming up to halo crater, we really got on a third type ground, which was ground that we discussed around the Surveyor crater which seemed to be the firmest, especially down in the crater. It seemed to be the most firm ground that we were on. It still had dust; we still sank in, but we sank in the least in the Surveyor crater, both going down to the Surveyor from the one side and going up towards the [/4 through that blocky crater on the other side, nearest the LM. The blocky crater was also an interesting feature and that may be something that we - I think we did discuss, though, as we stood there - was the fact that we felt that the Surveyor crater was an old crater, as if it h_ ' been impacted- -
CC: Hold up for Just a second. We're going to have to switch antennas, and we may lose you for a second.
CC: Apollo 12_ Houston. We've got a good signal. Go ahead.
CDR: Okay. I guess we discussed it that we felt the Surveyor crater must have been impacted very early and had bedrock, and that this bedrock had weathered down to where the crater was very smooth and had weathered much there; and along came another one and made this small blocky in crater tile side of it which must had been - which indicated to me that bedrock was not too far below the surface right where we were at the Surveyor crater. And, of course, we have samples of that. Something that A1 and I Just were talk- ing about - he wanted me to mention that the Surveyor, except for tile fact that it had changed color, looked in very good shape. This is true. But there's something that I noticed, using the cutters. Supposedly, the tubes that we used in practice were exactly the same metal and alumin_ that the Surveyor was made out of. And if this is the case, something very definitely happened to the metal, like it crystallized, because it was much easier to cut the Surveyor tubes except the one tube which I flat c_uldn't cut; and I their think that they were off on dimension on that tube. It must have been a much stronger tube than they'd indi::ated, much thicker tube, Page951 thicker walled tube. But the wire bundles that we cut, too, also had the appearance of being very brittle. They cut very, very easily. I was - Yes, the coating flaked off the insulation. And there was one wire bundle that had a cloth insulation on it which was not on our mockup, and there was a - The other wire bundle which was on the moekup wasn't quite the configuration that it was in the mockup. But these wire bun- dles seemed to cut quite easily, also. And I don't think it's because I was Juiced up, I think there was very definite crystallization or something there. You'11 get to see _hat with the stuff we bring back.
CDR: I guess the last most significant thing is that A1 and I and Dick also, having watched our training, were impressed with the fact that we managed to get as far out as we did. And that it was as easy going in that kind of country as iL turned out to be. The distance that we covered, I guess we covered a little over a mile.
CDR: You put that on Earth in your equipment - if you had lunar-weight equipment on Earth, you could never make that traverse in that time. You would die before you got to the end, aud we weren't even sweating; we were kind of hopping around out there doing the Job. The only thing that kept us from moving faster was there was l_ from studying more details at each site was the fact that we had to keep pressing on. So what's going to happen when we get back, we're not going to know all the details of each site because we Just weren't able to stay there long We could have spent that whole time in any of _hose craters, trenched _round them and looked at - collected different size rock - type rocks around it, and tried to go back and forth on th2 - check the blanket and see if we could discover any difference in texture and all that sort of thing. But the time Just wasn't avail- able. It waS one of those things of how much you want to cover in the time you've got to do it. Page 952 5
CDR: Yes, what Al's saying is we did Big Bend, Havaii, 2-hour Meteor Crater, and New Mexico all in one trip around there. That's about what it amounted to.
CC: Yes. You did a great Job in it, too. Hey, listen. When you looked into the craters, did you notice any boulder tracks that indicated there'd been many rocks rolled down besides the accumulations boulders ones you rolled down or of at the bottom of these steep slopes?
CDR: No, not any particular distribution. When there were rocks in the bottom, it was in these blocky craters where it looked like the material had been there.
