CC: Okay, and, in _he second block, the lower block, under the upda'_es for the times and angles, we have the following readings under the "Update" col,,mu. The GET of LOI ignition is "78:31:34.2," the second time is "79:01:34.2," and the angles are "144, 358, and 68." Over.
LMP: Okay, copied on the update time, "78:31:34.2, 79:01:34.2; 14,, 358, and 68."
CC: Roger. And, be advised, this also changes your little graph over on the side there. Primarily what it does, is to enlarge the mode 130 region by about 10 feet per second on either side and it -_ changes the "LCI plus 30 abort DELTA-V" line by essentially extending it and raising the left-hand corner Just a wee bit. We could read up the lines too if you want, but I'm not sure you really need those. Over.
CC: We're coming up on another OMNI switch, and we'11 be back with you in a minute, Jim.
CC: Okay, 15; we're back with you.
CC: 15, Houston; we're back up.
CC: Okay. We read you.
CC: Okay. Understand you really - didn't feel you needed the complete update to that graph, Jim?
CC: Jim, this is Houston. Is that a verify on the fact that you don't want the update on the graph? Over.
LMP: I think we can do it ourselves, Bob.
CC: Roger. Okay, and that's all the update we have for you at the moment. You might be interested in knowing that that water dump you guys scheduled last nighs before you went to bed, was at a very opportune time. Your PTC drifted plus or minus 2 and a half degrees all night.
CC: We'11 be up with the news in a while.
CC: 15, Houston. We have a PITCH of minus 30 and a YAW of 85 for the HIGH GAIN ANTENNA, and we'11 give you _ mark when to go.
CC: Go now.
CDR: Okay; minus BO and 85.
CC: And, 15, we're getting you on HIGH GAIN and receiving -
CDR: Okay; we understand you're getting the data.
CC: Roger. We Just want to confirm the position of the switches on the MAPPING CAMERA and PAN CAMERA. We have the MAPPING CAMERA on is STANDBY, and the PAN CAMERA POWER, OFF. Is that correct?
CC: Roger. If you finished, that's the correct position.
CC: 15. We'11 take OMNI Delta at this time, please.

CC: OMNI Bravo.
CC: Stand by, Jim. I'11 wait until the co_n's a little better.
CC: Hello, 15; this is Houston.
CC: Good morning, Jim. This is your friendly news reporter on duty now. And I wondered if you'd be interested in something from the local news- papers?
LMP: Oh, yes. We certainly would.
CC: Roger. This is frcm the MOCR Gold Bugle and Taglich $eitung News. The Administration effort to rescue Lockheed Aircraft cleared a major hurdle in the Senate yesterday when an amendment to deny favored status was rejected 60 to 35. Houston unemployment rose to 4.1 percent in June, an in- crease of a full percentage point from May, which is the highest in 6 years. And this morning's Post reports that the checkout of Falcon went on with a few words from Worden and virtually nothing from the other astronauts. However, I think that's incorrect, and I enjoyed talking to you very much yesterday. In sporting news, Houston dumped Philadelphia, 6 to 3, and is now in fourth place, 10 games behind the Giants. And an interesting note from the North. Bart Start underwent surgery yesterday for a bicep tendon transplant and will be out of action for at least 12 weeks. And that's all from the Daily Zeitung this morning.
CDR: Thank you, Joe. Enjoyed it.
CC: Roger, Dave. Good morning.
CC: Al, this is Houston. And we' re standing by for your null bias EMS check if you've gotten to that yet.
LMP: Roger. The DELTA-V test was good, and the null bias was 1.0.
CC: Roger, Jim. Just wanted to tell you to expect all your updates on time except the pad; and we're going to delay the pad to 72 plus 50 because of very good tracking data we'11 be getting in those last few extra minutes there.
LMP: Okay; understand. Expect the pad about 72:50.
CMP: Hello, Houston; 15.
CC: Go ahead, 15. This is Houston. We hear you now.
CMP: Morning, Jos_. Say; listen; on this - on the door Jettison photography, we've got about 50 percent left on MAG A, and we thought we would go ahead and use that.
CC: Good morning, Alfredo. We copied you, but I'm not sure that I understand your question.
CMP: Okay, Joe. No, it's not a question. Just wanted to let you know, on the 16-millimeter photography for the SIM door JETT, the Flight Plan called out MAG - stand by 1. Yes; it called out MAG Echo, and we're going to use MAG Alfa instead. We got about 50 percent left on it. Just letting you kn ow.
CC: Okay, Al. Thank you. And, by the way, is that the maneuver where the SIM Lay door jettisons the spacecraft?
CMP: It has been variously known as that kind of a maneuver, yes.
CC: Roger. I'm looking forward to that.
CC: Roger, 1_. I have a maneuver pad PC plus 2, when you're ready to copy.

CDR: Houston, 15. Did you get the gyro torquing angles?
CC: Roger, Dave. We got them. Thank you.
CC: Apollo 15, Houston. Requesting the high gain, when convenient.
CC: Apollo 15, Houston. Just a reminder to load the DAP and then go on back.
CDR: Okay, Houston. 15 with the burn status report.
CC: Go ahead, Dave. This is Houston.
CDR: Okay. I guess you could see it was a nice smooth burn. On time. Burn time was a second. DELTA-V gx at the end of the burn was .2; there was no trim; residuals were plus .2, minus .1, plus .1; DELTA-V was a minus 2.3. c
CC: Roger, Dave. We copy. And we think you're bragging, but you have a reason to. Beautiful burn.
UNKNOWN: all this nice machinery up here, Joe.
CDR: Okay. Suit pressure integrity check is okay. The flow was about .3 or .4. And we're proceeding into the setup for the SIM bay door jettison, and we'11 give you a call when we get everything ready, before we blow it.
CC: Roger, Dave, Sounds good.
CC: Houston, this is 15. We're ready to turn PAN CAMERA POWER on, if you are.
CC: Roger, Jim. Go ahead.
LMP: Okay. It's coming on now.
CC: Jim, we're not sure that the cameras are running properly. We want you to check the two SEB cir- cuit breakers on panel 5, in, and confirm for us that you got the right talkback when you turned them on.
LMP: The two circuit breakers on panel 5 are in. Stand by.
LMP: Joe, there's no talkback called out here on the PAN CAMERA POWER on.
CC: Roger. We copy. And, Jim, apparently, when you turn the power on, you should get about 2 seconds of barber pole, and then back to gray. It may very well have happened, and you just didn't notice it.
LMP: Houston, this is 15. Do you want us to turn the PAN CAMERA POWER on again and check that talkback a little more carefully?
CC: Jim, that sounds like a good - -
CC: - - idea to us. Would you turn the PAN CAMERA POWER OFF, wait 30 seconds, and then go back on, watching the barber - the - the barber pole indication, please.
LMP: Okay. That's in work.
CC: Roger. Go ahead. SM/AC
LMP: Roger. We have the POWER OFF, down on 180 [sic], per the P40 checklist. Should we put that power on?
CC: Jim, that's mffirmative. That power should be on, and that's probably our problem. Thank you.
LMP: Okay. SM/AC
CDR: Okay, Houston. The POWER is on, and the PAN CAMERAS are coming back to POWER at this time.
CDR: And we got a barber pole for 2 seconds.
CC: Roger. As advertised. Thank you, Dave.
CDR: Okay. I guess that's a spot in the cleanup of the P40 that didn't get carried over to the Flight Plan.
CC: 15, verify MAP CAMERA, STANDBY, please.
CDR: Stand by. Okay; MAPPING CAMERA going STANDBY.
CDR: The - the MAPPING CAMERA is in STANDBY now, but it required a - a change.
CDR: Okay; Houston, 15. I - do you want the MAPPING CAMERA in STANDBY for the door JETT?
CC: That's affirmative, 15. MAP CAMERA, STANDBY.
LMP: Houston, would you like the SM sector AC POWER OFF for the SIM door Jettison?
CC: That's righ-p, Jim. Per the checklist, the first one in step 4.
LMP: Okay. We just wanted to confirm it.
CC: Roger. Sounds like a good idea. I think we have a bug or two in this procedure.
CC: Apollo 15, Zfiouston.
CC: Roger, Dave. We're ready for PAN CAMERA POWER to BOOST. On your step 2 there, you are GO for SIM door Jettisen. And we want you to watch the FUEL _ CELL REACTANT valves after the jettison, per the checklist - just a reminder of that. Over.
CDR: Okay; understand. And we are in boost, and we'11 give you a mark when we blow the door.
CC: Roger. And we will be standing by for a __ description.
LMP: Okay, Houston; 15. SIM door JETT. - 3, 2, 1 -
CDR: Felt a little shudder, but not too much.
CDR: Okay, Houston. We have negative visual on the SIM door as of yet. And the fuel cells looked okay. The RCS Bravo primary talkback went to barber pole, and it's reset. And otherwise, no reaction in here.
CC: Roger, Dave. We copy. And we assume you didn't notice any debris of any kind either.
CDR: Nothing in particular, Joe, and Jim's got a visual now.
CDR: Okay, Houston. Jim's got it out his window, and he's taking pictures, and he says it's slowly tumbling.
CC: And, 15, just out of interest, we saw a good healthy jolv in our Doppler data down here during JETT time.
CDR: Gee, that's very interesting because I would say that the jolt in here was very minor.
CDR: Houston, 15. I guess the consensus would say that the - the shock was about one-tenth of the other pyros we've seen up to this point.
CC: Roger, Dave. We copy. Can you still see the world's largest lens cap out the window?
CDR: We'11 check. Tape _9/1
CC: Roger. We've looked ahead in - several hours in our Flight Plan, and we have - see no further inconsistencies between the checklist and the Flight Plan like the small problem we Just had with the power. So, Just wanted to advise you of - of this, and just follow the Flight Plan as usual. Over.
CMP: Okay, Joe; we'11 follow the cookbook. Thank you.
CMP: Houston, 15. Go.
CC: Roger. I've got a preliminary maneuver pad for LOI when you're ready.
CDR: Okay; stand by 1.
LMP: Okay; stand by 1.
CC: And, Apollo 15, if you'11 give us POO and ACCEPT, please, we'11 give you a preliminary state vector, target lcad, and a REFSMMAT.
LMP: Okay; you've got POO and ACCEPT.
LMP: And I'm ready to copy the preliminary pad, Joe.
CC: Roger, Jim. Just out of curiosity, has the SIM bay door long since disappeared from view?
LMP: Yes, I looked for it a few minutes ago and couldn't see it any longer. 49/2 Tape

UNKNOWN: Houston, this is 15. Did you get all the readback?
CC: 15, this is Houston. We're having a comm problem down here on the ground and I need to check still your NOUN 48 and your NOUN 33.

CC: That's all correct, Jim.
CDR: Roger. The LM/CM DELTA-P is .5. -
CDR: Roger, Karl. All the systems checks are complete, and everything looks good.
CDR: Okay, we've Just made a little mission-rules re- view up here, and I have one question for you - relative to the circuit breaker on bank A procedure at 6 minutes. Our interpretation of the mission rules says that, if we have a bank B ball valve close prematurely, then we would leave that cir- cuit breaker closed until shutdown, and close - or - or until 10 seconds prior to shutdown, using that as our good bank rather than closing it in 6 minutes. And this is in reference to the cue card - at the bottom where it discusses one ball valve closing prematurely.
CDR: Houston, 15. I'11 Just repeat it once here, maybe in simpler terms. If bank B closes prematurely, then we'11 leave the PILOT VALVE on A closed until 10 seconds prior to cut-off, instead of at 6 minutes.
CC: Roger. We _opy.
CC: 15, Houston_ We copy your question, and we concur.
CDR: Okay, thank you. Everything else I think we have squared away.
CC: Roger. Milt says we owed you a review before every burn. Are you interested in a quick runthrough of what happens at LOI?
CDR: Sure, why not. Let's do it.
CC: Okay. As I have it here, starting at T minus 2 - -_ T minus 2 minutes, we close the MAIN B PILOT VALVE circuit breaker. At T minus 5 seconds, we PRO. Then, the DELTA-V THRUST A and B switches both go to NORMAL. At T plus 5 seconds, we close the MAIN A PILOT VALVE circuit breaker; and, at T plus 6 minutes, assuming nominal burns, we open the MAIN A PILOT VALVE circuit breaker; and, after that, we avoid PUGS manipulation. And a reminder here is - don't forget to turn on the DSE because we're vitally interested in that single-engine burn performance.
CDR: Okay, Houston; we're right with you. We've Just gone through that, and - we understand it. Thank yOU.
CC: 15, this is Houston. If you'11 give us ACCEPT, we'11 send up a new state vector.

CC: And a note here from EECOM that, due to destratifi- cation in your oxygen tanks, you may get a eryo pressure Light; don't worry about it. That's during the burn.
CDR: Okay. Roger. Understand the cryo pressure.
CC: Gentlemen, everything looks perfect down here, and - all we can say is, "Have a good burn."

CC: 15, this is Houston. How do you ready
CDR: Hello, Houston. The Endeavour's on station with cargo, and what a fantastic sight.
CC: Beautiful news. Romantic, isn't it?
CDR: Oh, this is really profound; I'11 tell you, fantastic !
CDR: And we've got a burn status report for you.
CC: Okay. We're ready to copy whenever you're ready to give it.
CDR: Okay. I think our trusty pilot has a first for you on this one. Burn time was 6 plus 38, igni- tion was on time; the residuals were 0, O, and 0; DELTA-Vc, minus 4.8; the fuel, 33.25, the oxidizer, 33.3.
CC: That's a beautiful Job up there.
CDR: And it was a very smooth burn all the way, Karl. There was not a ripple. I guess the only little thing we might comment on was that we had a little PUGS operation after 6 minutes.
CC: Okay; we copy.
CDR: And, Houston, after our first few minutes of looking here, I don't think we'11 have any trouble new at all finding things for you for 6 days.
CC: 15, Houston. We'd like to know the position of the PU VALVE and also the UNBALANCE meter reading.
CMP: The FLOW VALVE is in DECREASE right now. The UNBALANCE is reading about - 25, and I put it in the INCREASE position for about 10 seconds after 6 rain - after 6 minutes.
CC: Okay, Jim. We copy.
CC: 15, Houston. _
CC: We've Just got through with the playback, and we've got excellent burn data down here. And, if you'11 give us ACCEPT, we'11 send up a REFSMMAT.
CDR: Okay; you've got POO and ACCEPT.
CDR: And, Houston. We're over Mare Crisium at the present time, and the sights are really striking. I guess some of the interesting things we've noted is the variation in albedo from white to dark gray with m_y variations of gray in between. And many times, this albedo change appears without any significant change in topography, other than perhaps a - a mountain ridge or a chain or a wrinkle ridge or something, but there are many vari - variations in the albedo all over the surface. I guess our general consensus is, it's gray. We haven't noticed any brown yet.
CC: Excellent. If I'm not mistaken, this is probably the first time men have been over Crisium.
CDR: I guess that's probably right.
CDR: We have everything from the very old subdued craters that are almost completely washed out to the very bright fresh ones which have interior walls of almost pure white.
CC: We're lapping it up down here. Keep talking if you feel like it.
CDR: Another interesting fact that - that we've all noticed is that it - it looks like a great desert across which we've had a number of dust storms. And, in many places, you can see the - the tracks or the swirls across the surface which looks like a - a great dust storm has been blowing across the surface - primarily indicated by the albedo change. -- But all over Crisium, you can see the streaks, which obviously are from impact at some point or another, but the impression we get is that the results of a dust storm.
CC: Very interesting; 15, the computer's yours.
CC: The computer's yours.
CMP: Karl, this is Al. I'd have to say pretty much what Dave's been saying. Might be interested to know that we're coming up over Pierce right now, and Just about to hit the west rim of Mare Crisium, and kind of looking forward to taking a look at Proclus as we get up a little bit closer here. There are a couple of craters just to the north - northeast corner, and we'11 pinpoint those a little better for you later. A very, very sm_ll crater that looks like it's had some dark material slide down into the crater, the eastern wall of the in- side of the crater has some very dark material in it, and at - at this Sun angle, it doesn't appear that it's shadow.
CDR: And, you know, as we look at all this after the many months we've been studying the Moon and learning all the technical features and names and everything, why - when you get it all at once, it's just absolutely overwhelming. There are so mAny different things down there and such a great variety of landforms and stratigraphy and albedo, that's it's hard for the mental computer to sort it all out and give it back to you. I hope over the next few days, we can sort of get our minds organized and get a little more precise on what we're seeing. But I'11 tell you, this is abso- lutely mind-boggling up here.
CC: Gentlemen, I can well imagine that a foreign planet must be a weird thing to see.
CDR: Roger. And we've got Proclus in view right now.
CC: Excellent. Tell us about it if you have a chance.
CDR: Well, the - the rays extending from Proclus are very light in color for about - they are very light color for about - oh, 240 to 260 degrees around, and then there's a region of dark mare or albedo. And our - our orientation presently with the spacecraft is such that we have - we're having a tough time figuring out north and south; and, once we get on an orbit track, we'11 be able to give you dirgction a little bit better. But the inner walls of Proclus are very light in color, almost white. The outer walls - the outer ring has a somewhat light gray appearance, and the difference in the - the rays is really between a light and a dark gray, as distinguished from the inner walls which are quite white. The - the walls exhibit some debris on the upper slopes, maybe the upper 30 percent. I can see, on one side of the - the crater, some On large blocks. another side, I can see what appears to be a large slump block or a large --_ slumping of the wall that goes about hal_,way down and takes about - oh, 15 degrees of the rim of the crater with it. The floor is very irregular and rough, almost constant gray - medium gray color, somewhat darker than the light gray on the outside rays and somewhat lighter than the dark gray on the - the surface, which does not seem to be covered with a ray pattern. There are a few ridges on the floor, arcuous ridges, and some domes which are quite prominent. And I'm sure when A1 comes back over here later on and has a chance to study it Carefully, he can give you a - a good accurate picture.
CC: 15, we would like to have TRACK to AUTO on the NIGH GAIN. And, for your information, the Saturn IVB impact is going to take place in Just a few minutes. It's going to be a - in a - -
CDR: Okay; very good. I wish we were in a - -
CC: Right. It's 2 minutes 40 seconds, but it's going to be out of your visual range, somewhere around the center area of the Moon.
CDR: Roger. It's too bad we won't get to see it. We'd already taken a look at the map to see if we'd have a chance, but I guess we'11 miss that one.
CDR: Houston, 15. We're coming up to Serenitatis, and it really looks like an ocean. The landforms, as are very rugged, very cratered, we approach, highly rounded, and we get to the shoreline and we see a few wrinkle ridges that have smoothed out. And we can see, on the far side on the horizon, the mountains which pick up again on the western side of Serenitatis.
CC: Roger, 15. We're over Serenitatis
CMP: Okay, Karl. coming up now. We're a]most over Le Monnier at the present time, and we can see the Littrow area just out in front of us. And it is, in fact, about three different shades. You can see the - in the upland area, and particularly what looks like down in the valleys, a darker color, and it does look like it's a light powdering- or dusting-over of the entire area. And then, as you get out further into Mare Serenitatis, there's another layering which is a little bit lighter in color. And then, out at the last edge of the wrinkle ridge, out beyond that is the last layer, and the rest of Serenitatis looks fairly - fairly light in color. So I'd say that the - the - the centeral - central part of Serenitatis is light, out beyond the first wrinkle ridge is a darker layering, and we're not up close enough to see what it is yet, and then as you get up into the highlands around Le Monnier and Littrow area itself, there's what - what appears to be a - a light dusting of dark material, and it cer- tainly looks volcanic from here. Off to - to the left of that to the south, we can pick up Sulpicius Gallus pretty clearly right now.
CC: Roger, Al. Sounds like you're seeing a marvelous amount of detail up there.
CMP: Well, after - after the king's training, it's almost like I've been here before.
CC: You can't help yourself, can you?
CDR: And, Karl, we're approaching the Apennine Mountains, and that is indeed a spectacular view.
CMP: Sure is, Karl. No question about those mountains being there and where we're at with them.
CC: They stand up on your horizon, do they?
CMP: Yes; tremendous relief as we approach the moun- tain, Karl.
CC: Roger. And, for your information, gentlemen, we're getting a good seismic signal from the impact of the Saturn IVB. Houston.
CC: 15, this is There is no update required on your T - on your TEI-_ pad.
CDR: Okay, Houston; understand. Houston, as we cross out of Serenitatis into the Apennines, why, it's Just - ,mweal. You know_ those are very poor descriptive terms, but the - the mountains Jut up out of the ocean here in great relief. I'm sure the guys who've been here before can probably sit down over a cup of coffee and tell you. But the relief is really pervasive.
CC: You're the first man to fly over this mountain range, Dave. I guess pretty soon you're going to be over the - over the landing site, aren't you?
CDR: Roger. But I'm afraid it'11 be dark today.
CMP: Karl, this is A1 again. Looking down into the Sulpicius Gallus area, looking at some of the wrinkle ridges and some of the rilles - the arcuate rilles down there, I can make out some distinct color patterns that seem to run parallel to the arcuate rilles - an_ along the wrinkle ridges, and there is a very subtle darker color, again almost as if it was - some kind of cinder fallout along the ridges and along some of the rilles.
CDR: And, Houston, we're coming up here on the termina- tor and the area I guess we call Crackled Hills really looks like crackled hills. If you distin- guish between the mountains, which are very promi- nent and smooth, the surface between the first small mountain range and the - what is now the terminator, is relatively flat with a very rough texture - very irregular, lower, crackled hills.
CC: We copy, Dave.
CDR: Jim's - Jim calls it a gun-metal gray, and that's a very good term, I think, for the color that we're seeing now. And as we approach the terminator, of course, the relief stands out even more. The shadows are getting much longer, and the peaks of the mountains, as they're silhouetted against the - the Crackled Hills, seem to have a - a diffuse shadow at the top. The - the shadow, as it goes from the base of the mountain to its peak, is very sharp. And around the top of the mountain, it becomes more diffuse, not - not quite as sharp and begins to blend in with the - the surface on which it's being cast.
CC: Roger, Dave. Sounds very interesting.
CDR: Houston, we're trying to get oriented here so we can perhaps pick out some of the features near the landing site. There's quite a bit of shadow now, but we have Aristillus and Autolycus very clearly. And with a low Sun angle, the surface between those two large craters and the rim of Imbrium - the eastern rim of Imbrium is very rough, quite a bit of debris, and it looks like it probably came out of the two craters. I be- lieve we can see Hadley C, Just barely on the shadows.
CC: Roger, 15. We copy that. Did I understand that the rim of Autolycus is standing up in the sunlight?
CDR: Yes, that's true. Aristlllus and Autolyeus both have their eastern rims exposed to the sunlight, and we get a pretty good look at the elevation on the rim. And Autolycus, to its northeastern side, seems to have a - a saddle or somewhat depressed rim, and as you come aroUnd to the west - the eastern side of Aristillus, it seems to be rela- tively level or horizontal, with a few subtle saddles and depressions. Autolycus appears to have a - a relatively horizontal or - or even rim all the way around, and we can see sunlight on the northwestern side of Autolycus on the rim, Just barely a tick of it.
CC: Roger. It soUnds like a fantastic view.
CMP: It really is.
MCC: You guys have enough to keep you busy for a few days then?
CDR: Hey, Dick, we got enough to keep us busy for months and months and months, as you well know.
CDR: The outer rims of Aristillus and Autolycus seem _ to be quite heavily cratered and rough; and Aris- tillus, on its east-northeastern side, seems to have a couple of benches on the outer rim as it goes' down to the surface, and their - the shadows are - are exposed quite well.
MCC: Roger, Dave.
CDR: Houston, Just north of Conon, there's a - a great depression in the moUntains - a low part of the mountains. In the - The western side of the mountains is exposed to the sunlight, and this reflects back into the shadow part of the mountains which - the base - basin Just north of COnon there is really shadowed by the eastern mountai n range; but the reflectivity back from the - the mountains exposed to the sunlight illuminates the - the shadowed area to where we can pick out craters and ridges and various other topographic features. It's - it's really quite interesting. As a matter of fact, Just to the - the inner walls or the in- ner basin of Conon itself is illuminated by its own reflectivity on its western wall.
CC: Roger. That soUnds like a fascinating illumina- tion. Do - do you have any inclination that you're going to be able to see the dark side of the Moon with earthlight on it?
CDR: Well, we can just barely see subtle features now, I think. We can see the horizon quite clearly.
CC: Roger. When you get dark-adapted, it may be that things will come through pretty well.
LMP: Roger. Houston, 15; go.
CC: Jim, the people down here would appreciate it if you could give them something of a description of the operation of the PU VALVE during the LOI burn.
LMP: Roger, Karl. There was no operation of the - the PU VALVE at all until crossover. And then at crossover, it required a - a DECREASE, and then at about - about 5 minutes and a half into the burn, it started to increase, and I went to the - the INCREASE position at that time. All the operation of the PUGS manual operation occurred after crossover.
LMP: And, as I mentioned, about 5 and a half, I went to - 5 and a half minutes, I went - went to neutral and then the - it looked like the UNBALANCE was going to go - it was rapidly departing the zero region, and that was about the time we went through 6 minutes, and I put it into minimum at that time - into the DECREASE position.
CC: Okay, Jim. That answered our next question.
CC: And, 15, the people down here were very much turned on by your description of the swirls on the floor of Crisium. We trust you got some good photography of that; and, if you didn't, they'd very much appreciate having some next time around.
LMP: Okay. We were discussing our photography, and we're going to try and stay as close to the pre- planned photos as we can and not overextend our- selves into what's already planned for the 6 days. --_ But we will use our spare - spare film Judiciously for the kind of things you hear us talk about that you'd like pictures of.
CC: Sounds very good.
CC: 15, this is Houston. Joe Just came up from below to tell us that Farouk and company are ecstatic about what you've told them so far and that all of the SIM bay experiments are looking to be in excellent shape.
CDR: Okay. The nk you, Karl. That's good news.
CC: 15. We have your torquing angles.
CDR: Roger. Torqued on the minute.
CC: Just to firm up our interest in those swirls on the floor of Crisium, the words we'd like to send up is that it'd be nice to get a three-photo convergent stereo sequence on it, and if you'd like settings, we recommend - -
CDR: Okay; three photo ...
CC: Roger. And if you'd like settings, we recommend f/8 at 1/250th with a 250-millimeter lens.
CDR: Okay, Houston; understand. Swirls on Crisium, f/8, 1/250th, three-photo convergent stereo, with a 250
CC: Roger. And now, you wanted us to remind you about your helmet and gloves when you take shots of Ingenuity this time around.
CDR: Okay; we'11 tell him.
CC: And, otherwise, we have nothing more down here. Everything's looking in great shape, and have fun on the back side.
CDR: Okay. Thank you, Karl. We will. APOLLO 15 AIR-TO-GROUND VOICE TRANSCRIPTION
CDR: Roger, Houston. Looks like we're getting locked up now.
CC: Roger. That looks better now.
CDR: Okay, Karl; while I got a minute here waiting on Crisium to show up, I'11 give you a rundown on what we've done so far.
CDR: Okay; we got the strips of photos of the Sea of Ingenuity - or Ingenii - and took a look at the light-colored swirls in the bottom of the mare. I couldn't tell - No elevation associated with those light-colored swirls, and they're very distinct when you look at them at this angle. Also - looked at the - at the area Just adjacent to Ingenii; there is a very definite valley that cuts through the edge of the wall there, and with what looks like a rille in the bottom, what's been described as Vallis Alpha Reed [?] - I guess it is kind of unique; it's the only one we've seen on the back side so far. We took some pictures of the rim deposits and then took a couple of shots going on out to Dumbbell. After that, we got set up for a Keyhole, took some convergent stereo on Keyhole, and got a couple of shots of The Bright One, along with some - some general pictures to show the ejecta pattern, al- though I'm afraid that eJecta pattern on The Bright One is not going to show up too well. It's - it's very bright but it's - it's also such a large area that it's kind of indistinct as to definition. And then - took a couple of what I hope will be conver- gent stereos of the - of the rooster tail along by Saenger. And then got on to Ibn Yunus/A1-Biruni/ Goddard complex and took some convergent stereo of the swirls to the - to the west of Ibn Yunus and to the north and west of Goddard. And now we're looking for the ones in Mare Crisium.
CC: Roger. Sounds like you did it up brown.
CDR: Well, it does look - sometimes brown, sometimes gray, Karl. But we'11 see when we get back.
CC: Hey, let's keep those colors straight, fellows.
CC: 15, we can take HIGH GAIN to AUTO now.
CC: 15, we need to go back to REACQ - on the HIGH GAIN.
CDR: Roger. REACQ.
CDR: Okay, Karl. Just a couple of general observations _ on Crisium while we're coming up on it. Proclus coming up from the east is really spectacular, you can very distinctly see the - the difference in the - in the color of the albedo in the excluded zone of Proclus, and as you're coming up across Crisium with Proclus ahead, you can see the ray pattern very distinct - extending out across Crisium - and follow the ray patterns almost as far as you like. And the excluded zone in the - in the ray pattern is Just very distinct at this point.
CDR: And, Houston, from this angle looking at Proclus, about a crater diameter out to maybe a diameter and a half or so, you can see many small bright fresh craters, which appear to be in the general direction of a ray, like part of the eJecta blanket.
CC: Roger. Dave, you mean to say that these small bright craters seem to be clearly related to the eJecta blanket. Is that correct? 53/3 Tape
CDR: That's the impression I get. They occur within a diameter to a diameter and a half of Proclus, and - they're about the same brightness as the inner walls of Proclus and they're small - Just small craters. I don't see any - Yes, I do see one which you might call a loop, which would suggest secondaries. They Just seem to lie in the general direction of the rays of the eJecta from Proclus.
LMP: They're sort of localized to one area which is - probably - yes, on the - on the western side of Proelus, northwest side.
CC: We copy that.
CC: Do you - do these small, bright craters have more or less a uniform size or do they come in varied sizes?
LMP: I'd say - Karl this is Jim - I'd say they're various sizes.
LMP: It is - I - I guess it depends, Karl, on - what do you mean by sizes, there are various sizes within a certain sorting. They - they seem to be fairly well sorted within one range, but within that range, there is a distribution. And they're all much, much smaller than Proclus.
CC: Okay, we copy.
CC: 15, this is Houston. If you'11 give us ACCEPT, we'11 send up a - a state vector and a target load.
CMP: Roger. You have it.
CC: And, 15, we don't require a PIPA bias check at this time. And I have a terminator photo pad when you're ready to copy.
CMP: And I'm ready for the terminator photo pad, Karl.
CC: Roger. The T-start is 81:44:10, and there's a note here that the PCM cable may not reach to window 3. And if it doesn't, go ahead and run on the interva - intervalometer alone. And this per- --_ tains to all future photography in window 3.
CMP: Roger. We understand.
CC: 15, we'd like to go to AUTO again, and go directly from REACQ to AUTO without a pause.
CDR: You're in AUTO.
CC: The high gain looks good this time; thank you.
CC: 15, Houston. When you can copy, I have both a D0I pad and a TEI-5.

CDR: Roger;
CC: 15, this is Houston. We're showing a low voltage on the battery relay bus down here. We think it's Just a matter of instrumentation, but there's a couple of procedures we'd like to run through here to check it out.
CC: Okay; first of all, we'd like to read - have an onboard read-out of the battery relay bus voltage, which is B-5 on the test meter.
LMP: Okay. That's 5-B.
LMP: It's reading 2.4 - No, I'm sorry, 1.4 - 1.5.
CC: Roger that reading.
LMP: Okay; Dave moved the - Stand by. Dave wiggled the and selector to the right - That's on B the position that backs the B position and now we're reading 3.5.
CC: Roger. And we Just recovered our read-out of - We got a good voltage reading down here now.
CC: Okay; thank you. We'11 think on that for a while and everything looks - everything looks fairly norm-1.
CC: 15, we have only one more question on that problem. And can you tell us what position you were in be- fore you went to 5-B on the test meter?
LMP: B was selected, Karl, but Dave moved the selector out of - Just barely out of B and back into the B position to obtain the higher reading.
CC: Roger. And what about the numerical side; was it in 5?
LMP: Yes, it was.
CC: 15, this is Houston. And I have a mRp update for REV 3.
CDR: Okay; go with the map update for REV 3.
CC: Roger. LOS: 82:28:16; 180 is 82:48:42; AOS is 83:14:54.

CMP: That - that's all in an agreement that I've got with Spencer, Karl. I think right now, we're too busy to do that, and after we get the landing out and start from scratch.
CC: Very good. APOLLO 15 AIR-TO-GROUND VOICE TRANSCRIPTION
CC: One more comment on the battery relay bus voltage. From all indications., it is indeed an instru- mentation problem, but we have one more question and that is to confirm that the MAIN A - MAIN BUS A and MAIN BUS B FUEL CELL talkbaeks are normal and - and have been normal during this period.
CDR: Yes, that's affirmative, Karl. They have been normal.
CC: Thank you. And, at the present time, all the systems, otherwise, are looking fine, and you're GO for DOI.
CDR: Okay; understand. GO for DOI.
CC: 15, this is Houston. We'd like to verify, over on panel 226, that the 02 TANK 50-WATT HEATER circuit breakers, i MAIN B and 2 MAINA are open. And, if they're not open, let's open them.
LMP: Okay. The two circuit breakers that are open are HF_2_TERS, 02 TANK 50 WATTS, i MAIN B, and 2 MAIN A.
CC: Roger. I understand they have been open. Is that correct?
CC: Okay. The reason we ask is that the temperatures weren't quite as we expected. Thank you.

CDR: Hello, Houston, Apollo 15. The Falcon is on its perch.
UNKNOWN: to hear you coming around that corner. How do things look?
CDR: Okay. Burn status report. Burn was on time. Burn time was about 24.0 - about half a second shorter than predicted; there was no trim; residuals were plus .6, plus .0, minus .1; DELTA-Vc, minus 4.4; fuel 29 - 29.25; and the oxidizer was 29.55; Unbalance, 100 increase.
CC: Thank you, Dave. We copy all that.
CDR: And I'11 tell you, it's really spectacular, when you can see the central peak of Tsiolkovsky coming up over the horizon before you see the rim.
CC: Hey, that's an interesting astrophysical observation.
CDR: And, Houston, 15. The G&N had us in a 58.4 by 10.0.
CDR: Houston, 15. We're in an attitude now in which we cannot see the surface. But our initial impressions after the burn, when we could see the surface, is that we were rolling in on a high- angle pass.
CDR: And, A1 Just added, we were.
CC: True enough. True enough.
CC: 15, this is Houston. You're STAY in the DOI orbit, and we have an orbit for you of 58.8 by 9.5.
CDR: Very good, Houston. 58.8 - 9.5 and we're STAY. Thank you.
CC: 15. You have a GO to proceed to the landmark observation attitude.
CDR: Roger, Houston. Thank you.
CC: And would you please give us AUTO on the HIGH GAINf
CDR: Okay, Houston; 15. We've got a little bit of visual - visibility now, and we're down in Crisium.
CDR: And it looks like we have enough altitude to get up over the western rim.
CC: You know, I sure hope so.
CDR: But it sure looks like we're looking up at some of those fellows out there.
CC: That must be sort of exciting, skimming along down there over the waves.
CDR: That's a mild word for it.
CC: Hey, can you see anything more about those sw - swirls? Anything interesting?
CDR: No, we're too close. And right now I've just finally picked out the rim of Proclus, and we're Just about level, altitude_wise, with the - the rim of Proclus. I can_not see down into it. I can see just a tad of_he southern wall. I guess we're Just north of it. I can see some large blocks on the outer walls.
CDR: But I'd say we're definitely at an altitude even with the top of the rim of Proclus.
CDR: Okay, Houston. We're coming up on the edge of Serenitatis now and I can look out and see a rille that runs parallel with the eastern edge. We're taking some pictures.
CC: Roger. I suspect that's Littrow Rille.
CC: And after Littrow Rille, you should be coming up on Le Monnier. Do you have much chance of seeing down at that angle?
CDR: I doubt it, Karl. At this attitude for the land- mark tracking, the windows are Almost out of it. Jim's got some visibility out window 5.
LMP: Karl, we Just passed the wrinkled ridges about a quarter of the way across Serenitatis, and the - there is definitely a topographic high in the mid- dle of the wrinkled portion.
CC: Are those ridges smooth, or do they show signs of lots of cracks in them?
LMP: I was impressed with the smoothness of the - the raised portion.
LMP: Okay. I'm taking several pictures of the wrinkled ridges that run roughly north and south in Serenitatis.
CC: Excellent, Jim.
LMP: In the one we Just passed over, there were some vertical fractures, definite vertical relief, in the smooth portion of the raised wrinkled ridge. The fractures were also running north and south.
CC: Roger, Jim. We copy.
LMP: Roger. It's a spectacular view as we glide across the Sea of Serenity, and I'm taking a picture now of a sinuous rille out to the north.
LMP: Okay. We're approaching the mountains now on the western side of Serenitatis. At this point, there's a wrinkled ridge running to the - the northwest.
UNKNOWN: Karl, this is Al.
