CC: Roger. I was Just talking to John about it a couple of minutes ago. Their view on 16 was - they didn't have any sunlit Moon, but they did have some pretty good earthshine.
CDR: Well, he - he knows what I'm talking about then.
CDR: Gordy, it's an unbelievable view through the monocular now. You can really see down in the depths of some of the larger craters and with a great deal of clarity. And you can see the - some of the higher ridges actually rolling right over the horizon as they go away from you.
CDR: Hey, Houston. As much as I hate to, I think we're going to have to maneuver out of this attitude.
CC: Roger. As you take your last look there, you're presently 20 - Just a little over 2000 miles up, and you're coming down about 4500 feet per second.
CDR: Yes. You'd better believe that.
CDR: Gordo, there's only one better view than this.
CC: What's that, Gene?
CDR: Right at the moment anyway. Right at the moment anyway, is to be out there and watching this space- craft maneuver in attitude and - and watch it burn over the lunar surface. I get the feeling someone is watching.
CC: Give us OMNI Charlie, please.
CC: Apollo 17, Houston. We Just had a site handover. That's resulted in the LOS time changing 19 seconds. It's now 43:21.
LMP: Okay; 43:21, and we are - we're on OMNI Charlie.
LMP: And Just to round out things as we pitch back into LOI attitude, lo and behold from over the top of the LM came the Earth.
LMP: Got the whole thing in one big package. can
CDR: Pretty interesting, Gordo. We - we can see we're right over South America and, of course, we can see up the Gulf Coast. And it looks like Houston is covered with clouds, but poetically enough, we can see the Cape, at least we can see Florida.
CMP: Yes, a VERB 41 NOUN 91. And I'm on VOX now. Get the commander's light. (Laughter)
CC: Ron, you're loud and clear on VOX.
CMP: Okay, Gordo. We're in attitude now.

CMP: Yes, but if - Okay.
CMP: Oh, my scissors flew up and disappeared somewhere. I'11 have a hard time eating if you guys take all the scissors with you.
CMP: But my teeth are pretty good though.
CMP: That's unless you start - start an hour and 20 minutes late, and then it's burn time plus 5.
CC: Apollo 17, Houston, If - if you three are inter- ested in sticking around awhile, you have our GO for LOI.
CDR: Roger, Houston. Understand. America is GO for LOI. And let it be known that the crew of America is GO for LOI.

CDR: America - Houston, this is America. You can breathe easier. America has arrived on station for the challenge ahead.
CC: Very good. We've been hearing you for a couple of minutes now. We've had a ground site problem, but you're loud and clear now.
CDR: Okay. That's what we sort of thought,'Gordo. The SPS burn could not have been more nominal. I've got some n,,mbers for you, if you're ready to copy.

CDR: It was an auto ignition. It was an auto shutdown. I think any comments during the burn are on the tape. But, to me, it was probably the smoothest and quietest SPS burn I ever remember.
CC: Okay, we copy that, Jack.
LMP: Okay, Gordo, did you by any chance get the S-IVB impact?
CC: We're - Okay, the new impact time for that is 89:39, so we haven't quite got there yet.
CMP: Ha, ha, ha, That's not true.
CMP: My big problem was all the holes were hills when I first started. Looked Just like you had the pic- ture upside down.
CC: Roger, Ron. I have a couple pan camera photo pads for you.
LMP: Go ahead, Gordo.
CC: Okay, the first one goes in the Flight Plan at 90:45, and the start time is 090:50:32. Stop time is 091:10:57. Go ahead.
LMP: Okay, I got 090:50:32 and 091:10:57.

CDR: And, Gordo, how did the spacecraft look to you as we came around?
CC: Real good, Geno. Nothing to report.
CDR: Very fine. Thank you. (Laughter) One little minor problem, Gordy, is that we're breathing so hard that the windows are fogging up on the inside for a change.
CDR: Be aut iful.
LMP: Oh, boy, there is Picard - or Peirce, one of the two.
LMP: Okay, Gordy, all those dark and light albedo changes around Picard and Peirce are not obvious at this particular angle yet. There's some hint of them.
LMP: The - rim - Is there one farther south of Peirce?
LMP: Which - is it far - Is the one farthest - Picard, yes.
LMP: Picard, I think, is the one I'm looking at. Yes, it is. Yes, and I can see Peirce now Just - behind the rendezvous antenna - or radar. And - Yes, way out there, you ought to start seeing them.
CMP: I guess I ought to get that other stuff on the camera, huh?
LMP: Okay. We're Just about over the top of Pieard, and the rim materials, which go out about a third of a crater in diameter, as near as I can tell, are - are distinctly darker but not by much. tsnuish gray of the rest of the mare.
CC: Roger. Now we assume you're all set up or about to get that way for the landing site photos. Yes, sir. There is no obvious ray pattern or secondary pattern outside of that blanket around Picard.
LMP: I see no loops or obvious alignment that would be related to that crater. There are blocks - look like great big blocky areas on the rim.
LMP: Do they want the 80-millimeter lens on these termi- nators now?
LMP: There 's Taruntius, Ron.
LMP: Yes, I guess that's right.
LMP: I've got to get another magazine on it.
P: - PU valve at this time for us?
CDR: Roger. It's in NORMAL.
LMP: Macrobius, Macrobius, my friend.
CDR: No, it's Microbus [sic].
LMP: Okay, I'm loaded up for your terminator, Ron. What's - is it not out of 105, or what? Is it - Okay, 80-millimeter or -
CMP: 8O.
LMP: 8O--
CMP: ... Millimeter ... f/11 at 1/500 ...
LMP: Okay. -
CMP: 12 frames.
LMP: 12 frames. Very good. How soon do I start?
CMP: Well, about-
LMP: Not Posidonius, Proclus. That's what I'm describ- ing. You know I - You're looking where?
CDR: ... 41.
LMP: Infamous Proelus. Okay, give me a mark when I'm - Hey, look at the - -
CDR: Okay, I'11 give you a mark, Jack.
LMP: At the Cauchy Rilles here. Man, is that neat. Let me see. Going to have to -
CDR: One right there with the shadowed peak in there. Right? Yes, yes, yes, yes, yes. And that's out of this window, huh? I'm not - sure I'm seeing it yet.
LMP: Manischewitz! Look at those terminators.
CDR: Shadows.
LMP: There's the mare domes for the central craters. They're certainly obvious. In - northern part of - Let's see-
CDR: The lineations that trend to the northwest through this entire - entire section - they go through the - mostly through the highlands.
LMP: I can get the pictures. Is it directly out of window 5? Okay. We've got about another minute and a half. I'm going to proceed here at 41.
CMP: It'11 be right underneath the groundtrack. It's right under it.
LMP: Well, that's the way we're going. I'm taking them east-west.
CMP: Okay. I ...
LMP: 0 - yes. Okay.
CDR: Hey, Jack, we're at - coming up on 40.
CC: ... about a minute to PRO on P20.
CDR: Yes. We're at 40 - Okay, I'm with you, Gordo. ThAnk you.
CMP: Okay, you got it.
CDR: Don't forget to PRO, Ron; you've got - you got 8 seconds.
CDR: MARK it - 41. Okay, I guess you can - -
LMP: Goes. With the usual FAO flight planning, that was a good time.
LMP: Hey, you can even see horizon in the - earthshine out there.
CDR: Boy, you sure can. You can see an earthlit hori- zon out there into the dark part of the Moon.
LMP: Can you see the landing site? I think it's going to be in the darkness.
CDR: No, I - it - The shadows are so contrasting here, Ron, that I -
CMP: Give me that thing a minute.
LMP: Donius [sic]. There's le Monnier, the landing site. I can't -
CDR: No, it's just - it's just dark.
LMP: Isn't it a little north of track?
CDR: No, I think it's right below us, Jack. I think it's right smack below us in darkness.
LMP: Yes, I yes, it is. I can't - I think I'm looking at Littrow right there, right below us. But I can't quite tell.
CDR: If I could see Vitruvius, I'd have a better handle on it. f/4 1/250
CC: A reminder to go to and on the last six pictures.
CDR: Roger. That's Posidonius all right, le Monnier; we' re here early.
LMP: Boy, I tell you, there's no question that right at the terminator you - you pick up relief that you normally would not believe is there in the mare. I remember Bill Anders talking about the appearance of a sea swell within the mare itself and that's certainly clearly shown right at the terminator. Unless you start to see the shadows from all the very small craters that otherwise don't show up as much more that Just little depressions, if that.
CC: Okay. We need ACCEPT so we can give you a landing site REFSMMAT.
LMP: Yes. Okay, I think that will do her. Okay, Houston. I cheated. I took three extra pictures, and those were at 2.8 and a 250th at the end.
CC: Okay, Jack. And,
LMP: your - actually your times might have been a little off, because I was Just about ready to lose the terminator bec_se of the maneuver - are we maueuvering or have we?
LMP: But, I think we got a good set going up to the term_uator.
CC: Roger. mag Quebec Que - No, mag Kilo Kilo as we came around the Moon and that number's now on 20. Kilo Kilo is 20, and Quebec Quebec is 42.
CC: Okay, we need the IR, ON, now.
LMP: Okay, back to work.
CC: It's your computer; the up-link's in there, and you can go back to BLOCK.
LMP: IR going ON -
LMP: MARK it. Yes, enough - enough tourist activity.
LMP: Warm in here, isn't it?
CC: America, a couple of items. Would you verify the S-BAND AUX TV switch is in the SCIENCE position? And one other thing, we think you were in LOW BIT RATE during the burn.
CC: Roger. We may have a problem there because it looks like LOW to us on the data. We'11 check further.
LMP: Hey, Gordy, there was - Ron questioned - brought up the question or possibility of not having gone to COMMAND RESET; but, just before we left you, you'11 probably be able to see that I went CO_$iAND RESET and turned on the tape, because I remember seeing the tape motion.
CC: Okay, Jack. We're discussing it - what happened there.
CC: America, you can go back to BLOCK.
CC: You're loud clear, Jack.
LMP: Okay. Before we really got concentrating on the burn, and I had an opportunity to - we all had an opportunity to look at Korolev, at a very low grazing Sun, one of the striking things was the - to me was the extreme absence of relief, the very smooth surface that existed in Korolev, independ- ent, of course, of the craters that are penetrating that surface. And it looked like there was a ring in the floor - outsi - next to the wall about maybe one-sixth of a crater radius that was somewhat brighter at the low grazing Sun, suggesting it may have had a different slope. And I believe I'm correct in saying that the inner floor maybe slightly raised. We'11 try to make other observations this next time around on that one, but there was Just a very smooth floor. The light plains material in that crater is very smooth.
CC: Okay; understand. One quick word from FAO's - -
LMP: And, of course, that's independent - -
CC: - - film watchers here, has to do with optional photographs. We'd rather you take the optional photographs on either OO or PP and reserve KK for the scheduled photographs. And, as it stands now, we've got to reserve 80 frames on either OO or PP for scheduled photography. Over.
CC: Okay, you have to keep track of that. We need - I wes hoping we had an optional capability on our first rev: and we'11 work it out. want
CC: We do. We just to put them on 00.
CC: That's right; just stick them on 00.
CC: Jack, the problem on the high and low bit rate there was a synchronization problem between you on the burn checklist and us on the ground on our pre-LOS command. No hardware problems, and I don't think it will be a problem in the future.
LMP: Okay. But you did lose the high bit rate. Is that correct?
CC: That's affirmative. We Just had low bit rate during the burn.
LMP: Okay. I may have jumped the gun on you there a little bit. But I thought we were supposed to do that Just before we went AOS - LOS. I think I did it about a minute before.
CC: Okay. It was a]most identi - simultaneous with our sending the command. You've got about 4 minutes to start looking at Copernicus coming here. Thank
LMP: Okay. you. We're Just - Sun's Just setting.
LMP: Okay, I have a visual on Copernicus.
CC: Aud by the way, the S-IVB crunched in on time, and it's been ringing the ALSEP seismometers like mad for some time now. 59/13 Tape
LMP: VOX, and that's VOX. How do you read the LMP, Gordy?
LMP: Thank you. Okay, good. All right, I've got a visual on Eratosthenes and Copernicus. The - there are obviously different-age craters in this light. You can see the ray patterns in Copernicus moderately well. You can even tell that they do cross Eratosthenes. Stadius shows up as a very clear dark area to the southwest of Eratosthenes. Now, one of the things that we mapped on the southeast and south rim of Copernicus were dark albedo areas within the eJecta. And those are apparent here, very clearly. And also, within - on the upper portion of the rim and on the benches, in that quadrant. The walls- there are the dark spots - lower albedo material that we mapped. They are - form linear patterns along the benches, apparently. Although the bench - the topography is not too clear. But the dark spots are in arcuate linear arrangement parallel to the rim. And they appear to have - be elongate along radius - along the radius of the crater.
LMP: This is in the southeast - southeast quadrant I'm referring to. Copernicus H is also very obvious as a dark-rimmed crater, relative to the albedo of the ejecta blanket. And the northwest quadrant, which we mapped as a smooth floor material and somewhat darker albedo, is just as apparent here, although all the contrasts, of course, are less. The main thing that you can pick out in earthshine are albedo distinctions. Now - now we - we - I remember that we also, at one time - and I can't remember whether it made the final map or not - mapped an arcuate fault structure, based on the change in albedo. And this was on the southwest quadrant of Copernicus. And that crossed the southern rim, more or less north-south, went down and curved across the floor and up the southwest rim, and that is a very clear arcuate pattern in this lighting. Darker albedo than the rest of the crater. And along the arc, there appear to be a couple or three even darker spots - much as we thought we saw in some of the early photography.
LMP: There is a general streaking - radial streaking - within that arcuate dark area that radiates radially from the crater, and if I had to project, the dark area would, - north - whose northeast terminus is the arc in the crater, I'd project it off to southeast about crater diameter and a half, maybe. Now there's - I'm getting - essentially directly overhead, and again the dark spots within the crater wall are still apparent, and the stre-_iug or the radial elongation of these spots is clear. Now, on the lower wall - that's below the first bench - I can see four of these dark areas, and on the next wall above that, above the first bench, there are two - two obvious ones and a couple that are somewhat more subtle.
LMP: In the middle of the - -
CC: - - Can you see anything of the - that stuff we were wondering about in the central peaks?
LMP: No, Gordy, I can't. The - there's very little indication of relief in earthshine and particularly at this high Sun aug - high Earth angle, pardon the expression.
LMP: The central peaks do stand out, though, as a much lighter albedo area within the crater. It looks to me like the best thing you can do in earthshine is work with albedos. Knowing the general topog- raphy from the - from the pre - earlier photog- raphy. We're coming up on Kepler now. Copernicus is out of E_f view in window 5. Maybe Ron sees it. Do you, Eon? nV
CMP: No, it's out of view now, too. Okay, we, we - -
CDR: Can you see Reinhold over there?
LMP: Reinhold, I was not conscious of. Yes, I can see Reinhold. Reinhold is one of the craters just like Copernicus that may have contributed eJecta into the Apollo 12 soil. Do you see anything - -
CMP: An S - an S-IVB - 16's S-IVB hit out there to the south, I think.
LMP: Well, I don't -
CMP: No, I don't think you'd see it.
LMP: I don't see anything that would indicate that. Reinhold is an Eratosthenian Age crater, as you may recall. It's crossed, very obviously even in this light, by the Copernican rays, which is prime - the m_in way we determine the age, other than it doesn't have any r_ys itself. Although, on the good photography we now have, we know it has secondary crater patterns around it.
CDR: You're not looking at the same crater I am then.
LMP: Reinhold is right down here, Geno.
CDR: Where are you looking ...
LMP: Well, it's south of Copernicus.
CDR: Okay, I'm looking up here.
LMP: South and a little west.
CDR: I don't have the same view you have.
LMP: Okay_ I can see Lansberg now. And I'm afraid I can't shed any light, pardon the expression, on the old question we've had about the age of Lansberg relative to the mare.
CC: Okay. Kepler ray pattern is very striking in this light - an anastomoting - losing series of - of bands which only average being radial. In most cases, they're a little off radial, but by Joining together, they give you a general radial pattern. wanted
CDR: I Just to see a -
LMP: Okay. Out the window 4, I have an excellent view of Kepler. Once again, albedo differences, such as the - are very clear - such as the distinction between the wall - light - or brighter wall materials and the rim which, in itself, is brighter than the surrounding mare. We can look right down some of the rays, aud the rays are not completely linear. I'm looking now to the northwest. Gene, you can see Aristarchus way up there in the northwest. See it?
CDR: Yes. It 's coming into ...
LMP: You ought to have a good view of Aristarchus. Very bright, up in the northwest part of our field of view.
CDR: The inside of that crater almost looks as if it's backlit.
CDR: Yes, they're all radial, though. IMP They are radial, in general. But when you look at them in detail, only portions of them are radial. And a single ray, which you can follow continuously, will bend and then curve back.
CMP: The - it's unique. We've got rays from - I guess those must be Copernicus over here - those long ones out to the right, which you might not be able to see. Kepler and Reiner are all - all intermingling up here.
LMP: Yes, this is the area now we're going over where the gs_ ray work on 15 indicated a relatively high radioactivity. And - not yet, it's -
CMP: Houston, America here. Do you see the torquing angles? I was going to look for the Hortensius domes near Copernicus, but got sidetracked with Kepler and missed them.
LMP: They are not obvious, though, in looking in the general direction -
CMP: Okay, I'11 torque it to 845.
CC: Roger. Once again,
CC: Okay. And as you get the camera set up for the orbital science pictures of Galois would want to change and use magazine OO instead of KK. That's listed in the Flight Plan at 90:20.
LMP: Okay, we '11 - we '11 do that.
LMP: We can see the area where Marius Hills should be, although it's not an obvious topographic feature in this light. Still see Aristarchus off up there shining like a star, if the Moon could have stars.
CDR: You squared away?
CMP: It's good to be able to see some stars out of the telescope. It's the first time I've been able to see any.
LMP: Gordy, we have a - a very clear zero phase point for the earthlight. It's certainly not a strong contrast for the Sun, but it's out there. And within it, again, the fresh craters tend to brighten - quite a bit more than the surrounding re,re. Still looking at Oceanus Procellarum. And now, out window 3, up to the northwest, Grimaldi is starting to show up - a very obvious dark area within the highlands of that part of the Moon - smd one of the darkest mare regions that we have seen on the - on the Moon. It's comparable, at least in the photographs, to that of Tsiolkovsky.
CC: Normally, of course, we think of the dark mare as being the younger basalt flows that - on the Moon, but in our case, of course, young means something on the order of 3 billion years or older. 60/1 Tape APOLLO 17 AIR-TO-GROUND VOICE TRANSCRIPTION
LMP: For our interp - If we can extrapolate from the samples returned by other missions.
LMP: Amazing how far over -now the highlands to the west of Procellarum are - still are bright, and the contrast between fresh craters and the normal high- land are very - are very obvious still in earthlight, particularly along the zero phase point with respect to the Earth. Rima GAmma now is - is coming a lit- tle bit closer to our oval track in the horseshoe in the - larger and more western end of it; the dark horseshoe is quite clear in this light. It's a west - or northwest-pointing horseshoe, as is the complete trend of that strange feature. I think Ron is going to have an excellent chance to study these light-colored swirls within the mare and other parts of the Moon. We had some good views of them and Mare Marginis and to the east of Crisium - Mare Crisium, and he should - if there is anything to be seen, he should be able to see it for - during the next few days.
CDR: Say, Gordo, something I Just noticed here in work- ing with the GDC what-have-you. I - looked at the Pc gage, and in the Pz - Pc position, there is a continuous bias on it now of about, oh, 7 percent, and if I switch to ALPHA, it goes to zero. We never saw that bias before this last burn.
LMP: Hey, Gordy, I'm looking right up the western edge of the Procellarum mare where it contacts the - the - the high - western highlands of the Moon, and we're Just about to fly a little bit south of Grimaldi. That edge is very irregular. There is no obvious indications that it - there are large basins that have been flooded by mare that have formed that edge, but, again, the topographic dis- tinction's possible in this lighter small. Now I'm starting to see that there are shadows in the craters.
LMP: That's the small craters. There, in the Mare Procellarum closest to Grimaldi, there are two arcuate rilles. Look like they are probably V-shaped in their cross section. I'm sure we've seen those on the photographs much better than I can see them here. Those - the rille patterns, though, do seem to project over into the highlands.
LMP: To the north of that - to the north of that bay of mare. Just interrupt.
CC: Oh, yes?
LMP: It was just out there north of Grimaldi. Just north of Grimaldi. You might see if you got any- thing on your seismometers, although a small impact probably would give a fair amount of visible light.
CC: Okay. We'11 check.
LMP: It was a bright little flash right out there near that crater. See the crater right at the edge of Grimaldi. Then there is another one north of it. Fairly sharp one north of it is where there was just a thin streak of light.
CC: How about putting an X on the map where you saw it.
LMP: I keep looking occasionally for - yes, we will. I - I was planning on looking for those kind of things. Starting to see the edge of Orientale, Gordy. Way off to the west. Hey, just yell, Gene, anytime you - -
LMP: Gordy, to the north of Grimaldi there is a large basin that is about the same size but only incom- pletely filled with mare in its northeastern quadrant. The rest of it looks like a fairly ir- regular and h_mmocky floor material of some kind.
LMP: But it's almost the same size as Grimaldi. It even looks like it is a little bit deeper, but, of course, Grimaldi has considerable fill. Grimaldi on its eastern edge has some of the graben, or it's rim, if you will, is cut by three or four anastomo- sing grabens that make it look like some of the bench areas in the larger basins.
CDR: I'11 turn off the intercom.
LMP: It has some very bright east-facing slopes, and you can see the bands of mare that are filling the - both the first bench area and the inner bench.
LMP: Any time you need us, Gordy, Just interrupt me.
LMP: Now, as I look north along the first bench, that's the first bench from the outside, one inside the Cordillerian ring. I better check that; I may have my names mixed up. Got Orientale, there - handy? See it. Should be on there. Yes, this is what I need. What's the name - they got a name on that ridge, there? That's Rook Mountains. Yes, the Cordillera. Yes, that's right. Looking Just west of the Cordillera on the first bench, as I look north, in this light, which is casting some shadows now, Gordy, over in the area, it looks extremely smooth. Now this is not mare; it's lighter albedo, lighter reflectivity than the mare, and, although there are patches of mare in the lower areas in it. But looking along that plain, in fact, a lar - long linear plain, it - it looks quite smooth with only some very broad undulations that appear to be roughly radial to Orientale itself. The more - closer we get to it, the more I see minor relief showing up. I start to see the shadows, I guess. And that relief seems to bring out a hummocky tex- ture in - in addition to the craters you would expect to see there.
LMP: I won't try to give you a trend on the hummocks because I think the shadows are biasing my view; they do appear to be north-south trending, but I think that is because of the shadow patterns. This is a spectacular sight, you guys; you ought to take a look at Orientale. One of the largest fresh basins on the Moon. It still is probably 2 billion years old, or 3.8 at any rate, if our dating cri- teria are any - any good. It has the outer Cordil- lerian ring and the inner ring called the Rook Mountains - very, very nicely shown. There are massifs on that inner ring, the Rook Mountain ring; there are massif complexes much like what we'11 be studying at Taurus-Littrow. There are low areas, non_mare areas, that are comparable to some - to the Taurus - the valley that we'11 be landing in. And, all in all, I think we'11 find that our ring in the Taurus-Littrow area around Serenitatis is comparable in many regards to this Rook Mountain ring around Orientale. You want - did you interrupt, Gordy?
CC: No. I didn't say anything.
LMP: Okay; I thought I heard your key. Okay; in the inner portion of Orientale, as we approach a ter- minator, the lighting is still excellent. Matter of fact, it appears brighter than what we were looking at over at Copernicus. Now, part of that may be we're seeing much sharper relief since the slope - Earth-facing slopes are nicely lit, and the backfacing slopes, of course, are in shadow. The first portion of the bench inside the Rook Mountains is partially filled by mare. Now, the higher land in there is very smooth, in a gross sense, is a very smooth hl_mmocky terrain, cut by roughly circumferential grabens. The trend of the hl_mmoeks themselves are not radial; they're more - well, they're about a 45-degree angle to the radius. They, in detail, have a much finer hackly texture, much like we've been able to see on photographs before. And, in general, you get the impression that, in several areas here, that that hackly tex- t'mred surface is draped over material that resembles the massifs of the Rook Mountains themselves. There's one area just to the north now of our track where there's a large, roughly equidimensional mountain mass, with a few projections of massiflike peaks through this hackly textured surface.
LMP: There are also some radial grabens; I just now picked one up, which we've also seen on the Orien- tale photographs taken by Lunar Orbiter. It's amazing how fresh appearing this basin looks, con- sidering its great age. But it's - it probably is not - had any more violent a history than Imbrium. Now, we're getting up, Just about to go over a delta-rim crater that's out in the basin. I don't remember the name of it offhand. But it's - should be familiar to some of the geologists who have mapped this basin. It does not appear to have a strong impact eJecta blanket around it. It's filled with mare, and it's quite sharply in contrast to a cra- ter of comparable size to the northwest. See that one, Ron; I don't know whether you can get it. I get a good view out of 5 now of that one. And, once again, it looks as if this hackly textured material that forms the higher hills in the inner bench - has a draped appearance over the, over preexisting terrain, and, in fact, along the ridges of the hmlmmoeks, you - we now can pick up little rilles that roughly parallel the hummocks, although not - not - not consistently. They do cross down into the valleys. But it has appearance that there may have been a tensional relief along the crest of each of the hl_mOcks, or many of the h-mmocks.
LMP: Delta-rim crater Just as has been, I think, dis- cussed in the literature, has just that delta rim with no obvious ejecta blanket around it, com- pared to other larger craters within the basin. We're directly over that crater right now. It's filled with mare, very smooth mare. Matter of fact, within that fill, I can see no - no craters. Getting very close to the Earth terminator, but you see good texture in the eJecta blanket of the large crater in the north part of the inner basin of Orientale. The radial ridge and valley patterns are very clear; the concentric coarse hummocks near the rim are apparent; and you can even see the second - patterns of secondaries, the larger sec- ondaries, extending out away - radially out away from that crater. The south - the mare fill in the south floor of Copernicus, I mean of Orientaie, is very smooth but does have the sea-swell texture that we saw over in Tranquillitatis. getting close to AOS. Do you have some words for us?
CC: Okay. We show about 9 minutes to LOS. We'd like to clarify one thing, and that was on this tape recorder commands and high and low bit rate. And we Just want to make it clear that preburn the 6 minute callout is HIGH BIT RATE, RECORD, FORWARD, COMMAND RESET. Did you - did you tell us a few minutes ago that you did indeed do all those at about 6 minutes? specifically - I know the HIGH BIT RATE was there, because we switched to LOW later. I can't - I'm afraid I can't specifically verify the COMMAND RESET. after the bus stars came on, we called that out. I'm almost sure Jack did get it, because I had him then check the helium valves and the nitrogen - helium and the nitrogen valves. to determine if we do have a switch problem. The INCO did send LOW BIT RATE, COMMAND, Just prior to - to LOS there before LOI, which is the way it's called out in the Flight Plan. And then you should have come along later with a COMMAND RESET, setting the switch to HIGH BIT RATE, and the COMMAND RESET switched into HIGH BIT RATE mode, and for some rea- son it did not go into HIGH BIT RATE. around? 60/7 Tape
CC: That's a pretty good thought. I think we will. On stand by. We'11 give you - we'11 figure out how we're going to do it here.
CC: Okay, Jack. We just now commanded LOW BIT RATE, and you're in LOW BIT RATE. We'd like you now to select HIGH and COMMAND RESET.
LMP: Okay. Gordy, you also have an oscillation in up- link signal strength and a clicking in the - in the audio. Do you read? We just switched steady and at about 60 percent - 70 percent signal strength.
CC: Roger. We hear that.
LMP: Okay. I'm going to - you want me to go ahead and command HIGH and COMMAND RESET?
CC: That's affirmative. The HIGH GAIN just went WIDE BEAM, but we're still reading you loud and clear. Go ahead in HIGH BIT RATE and COMMAND RESET.
LMP: Okay. HIGH BIT RATE; COMMAND RESET.
CC: Okay; it seems to have worked properly, Jack.
LMP: Okay, Gordy. I may not have got the COMMAND RESET at 6 minutes. I - I - I Just can't tell you right now.
CC: Okay; I want to assure you it was no big problem as far as the burn goes. No great loss there.
CC: America, Houston. About 5 minutes to LOS now. We'd like to have you go ahead and get the jet inhibits and the covers open as shown in the Flight Plan so we can see that before we lose you.
LMP: Okay; Gordy. IR COVER is coming OPEN.
CC: Roger. Okay; UV COVER coming OPEN -
LMP: And you want me to stay in HIGH BIT RATE?
CC: That's affirmative. You're there. You're going to have to do it in a minute anyway, so since you're there already, stay there.
C: roll has been changed, and you should have the proper jet configuration now.
CC: Okay. We see it; it looks good, Geno.
CC: Roger on that. Okay. Okay.
CC: Roger, Ron. Read you loud and clear.
CDR: Okay, Robert. We should have gotten everything right on up through AOS here in the Flight Plan.
CDR: And the pan camera should be running right now.
LMP: Those frames that Ron mentioned - this is Jack - that he mentioned were taken of a area where there's a much lighter gray albedo. Rather than the tannish gray, it's pure gray material that generally is on the rim crest of a number of craters. It may be related to the swirls that we see elsewhere.
CC: Roger, America. We're tracking you on the map here, watching it.
LMP: A1-Biruni has got variations in the - its floor, variations in albedo. It almost looks like a pat- tern as if water were flowing on a beach. It's that irregular. Not in great areas, but in small areas around on the southern side, and the part that looks like it's a water-washing pattern is of a much lighter albedo, although I cannot see any real source for it. The texture, however, looks about the same.
CMP: And Houston, America. For your info, it took an hour - an hour (laughter) - a minute and 45 seconds for the map - your mapping camera to extend and a minute and 45 for it to retract.
CC: Roger, Ron. Copy. l:h5, extend and retract.
CDR: Bob, what's our altitude now?
CC: Looks like you're crossing - you're Just about 90 miles, but we'11 firm that up here, Gene. You're 90.8 - -
CC: - - America.
LMP: Bob, this is Jack. And the question of these ir- regular swirls that we've got in Mare Marginis, and we are looking Just north of Nep - Neper now. I tell you, in the mare, there just is no visible relief. Although there seem to be some sinuous systematics anyway to the distribution. Like, there'11 be a very dark area associated with the light area. And that dark area is darker than the mare. I think the pictures'il show that. Now, in the highlands, however, the - the light albedo areas, which are very comparable, that appear to be swirllike patterns of the same type, seem to be associated with a crest of crater ridges and other high points. We're on over - right over a concen- tration of these now in the northern part of Mar- ginis, where the rule of a - of the light areas being associated with a - either - either spf,,,,,et- rically around a much darker area than the normal mare, or on one side, and in this case, generally the south side - of a dark area is - that rule is very clear. And that also seems to hold in the back side that there was a slightly darker region be- tween areas of light-colored swirls.
CC: Roger, Jack. We understand, and we're standing by. We have a DOI pad and some other updates.
LMP: Okay. We'11 go back to work.
CC: America, Houston. We'd like PAN CAMERA, OFF.
CDR: You're reading our minds, Bob.
CC: PAN CAMERA's OFF, and we'd like ACCEPT. We've got the DOI target load, the CSM state vector, PIPA - and an SPS tailoff constant.
CC: Roger, Gene. And there will be no PIPA bias.

CDR: We can now, I think, see contrast down in the shadow. And the only part of the scarp that is visible - I think Jack picked it out - as being right where Lara is.
CC: Roger. America, Houston.
CC: Roger. Just some words in your - You'11 be going through your systems checklist here and you'11 probably see that it says dump the waste water if it's greater than 85 percent and you are at about 89.6 percent. We'd- we'd like you not to dump the waste water until the nominal time in the Flight Plan. Do not dump the waste water during this systems check. Over.
CDR: Okay, and I understand that was about 94 hours as I recall.
CC: That's affirmative. That's where the nominal time is and that is where we'd like it dumped.
CDR: Bob, that's a - a fantastic black-and-white shot of the landing area with the shadow stretching across most of it.
CDR: Bob, I can now see down in through the shadow. I can see - Bare Mountain. I can see - I can't really make out the - the slide yet. Most of the North Mass - Massif are still in shadow due to the - due to the Sculptured Hills. And Just at the point where we can start really to see through the shadows and see the - some h%,mmocky terrain on the North Massif, it Just went out of my next reach. But, I did see some sort of albedo change that went across the canyon about in the vicinity of the - of the scarp.
CMP: Yes, it looks like the old gravity gradient worked there or something. I didn't see it get out of attitude at all. Did you all see any movement at all?
CC: Max er [error?] was about 0.2 - 0.3 of a degree, Ron.
CC: Jack, it's not required to go back and do them again; we watched it on telemetry.
LMP: Okay. I'11 try to remember to be a little more informative.
CC: No problem, Jack; no problem.
CC: Roger. We see them. They look good.
CMP: Just for another little matter of interest - once the Earth is in the field of view, which it's about - looks like it must be about 12 degrees from Regulus - it's so bright, that it blacks out any - blanks out the telescope for any star recog- nition. However, it worked real good in the sex- tant. You can see the star real well. You Just have to assume it's Regulus, though.
CC: Roger. Would that star angle difference - -
CMP: Okay, I'11 torque at 30.
CMP: I torqued at 30 - 09:30.
CMP: And the first - the first star angle difference was -you know, you can get a little bit lax about it - if you want to spend a little time at it, you can get five balls every time, looks like.
CC: Roger, Ron. With that star angle difference on the second one, I can assume it was Regulus. I think you're safe in your assumption.
CMP: Oh, yes. Right.
CDR: He had to do it, or else I'd have to go down there and do it.
CC: America, Houston. P40 looks good.

LMP: And there still seems to be no relief associated with it. Although, in many cases, it seems to follow ridge lines, or crater rims part way. In other cases, it's quite irregular in its distribution.
