CC: Roger, 15. We copy 1000 on the OPS pressure. And we have a suggestion down here that may make the OPS - simpler to handle. We'd like to put the hose over its connector there and simply turn the OPS on to bleed down gradually and simply replenish the cabin pressure and then you don't have to bother with you - operating it tonight.
CDR: Roger. That sounds like a pretty good idea. Okay; we '11 do that.
CC: Roger. And then everybody will be completely satisfied that it's bled out by the time you reent er.
CC: 15, this is Houston with a couple of comments about the SIM bay experiments, if you're willing to listen.
CDR: Roger Houston. Go ahead.
CC: First of all, on the gamma ray experiment, Dr. Arnold reports that A1 Worden probably performed the first recorded repair of a scientific instru- ment in space, because earlier in that day he'd begun to experience some problem with excess noise in the gR_ma ray experiment. And when A1 went out in the EVA - we don't know what happened there - but at the end of the EVA, the gamma ray cleared up and has been doing beautifully ever since. You must have given it a pretty good kick there, Al.
LMP: Well, not - not only is he a plumber, he's an electrician as well.
CC: Roger. On the X-ray spectrometer, the work you've been doing on the galactic sources of X-radiation has - is already showing considerable interest. And, in particular, the Scorpius X-ray I data gives us a longer continuous observation of - of this source than we've ever had before and shows a fairly long-period variation, whi - which - I - with - I should put in a word of caution - which still might instrumental, be but looks real, and was previously unrecorded and has the - has Dr. Adler rather ex- cited. And I'm sure the other as - astronomers will be much interested also. Indeed, we may go back to that source later today, although I don't think that 's clearly decided yet.
CDR: Roger. That sounds interesting.
CC: And otherwise, I guess - that - that's about the most exciting news from the SIM bay. talk
CDR: Okay. Very good. We're ready to about entry stowage, if you'11 get out your - your map and your little legend there - -
CDR: - - ... and we'11 run down the line here.
CC: Okay. We've - incidentally - one more comment, the mass spectrometer, on the retraction sequence yesterday, showed us no increase in contamination, which was something of a surprise. And it's prob- able that we might try that once more today to make sure that there wasn't some sort of instru- mental difficulty there. Maybe we just have a cleaner spacecraft atmosphere than we thought, though.
CDR: Yes, from what A1 said when he was looking around out there, it sounded to me like things were pretty clean.
CC: Okay, 15. If you will turn off your squelch it will help, because we may occasionally have periods in - when corem is rather weak. And, otherwise, go ahead. ---
CDR: Okay. What - what we use as a reference is the entry stowage map, spacecraft ll2, 26 July 71, which is in the front of our Flight Plan. And, if you have that in front of you, why, I'11 just go through that and give you the additions, dele- tions, and changes, of which there are very few.
CC: Okay. We' re - Stand by one moment.
CDR: Okay. A-1 is stowed as prescribed there. Top of A-1 has a bag - a decontam bag in which we have sample container number 2, for 23 pounds, and the I_ return items.
CDR: A-2 is as you have listed.
CDR: And, on top of A-2, we have the ISA decontam bag, for 64 pounds.
CC: We copy. and
CDR: Okay. A-3, A-4, A-5, A-6 are as you have on your list right now.
CDR: A-7 is as you have on your list, with the addition of the LM DAC and the I_4 - 70-millimeter camera that failed on the surface, which we thought you might like to take a look at.
CC: Right. Both of those are - are added items, I take it?
CDR: Side of A-7 is the EVA umbilical and bag, as per - perscribed [sic].
CDR: Top of A-7 is sample collection bag - 0h, stand by.
CDR: Okay. Let me - let me go back and make a correc- tion here, Karl. Look over in the left-hand column where it says top of A-l, and scratch "Sample col- lection bag number 2 ."
CDR: And then go back to your right-hand col_mn there. On top of A-7, we have decontam bag with sample collection bag number 2 and the BSLSS bag, for a
CC: Could I clarify that - both of those bags together were 48 pounds, or do I also put over the 20 - the 23 pounds we had on A-l?
CDR: Okay. And then, in A-8, it's stowed as perscribed [sic], with the exception of one less lightweight headset, which is some - somewhere on the Moon.
CDR: Okay. On the side of the next page in the left column, on the side of A-8 in the bag, as you have there, with the additic_ of the core tube pole.
CDR: Okay. I - I figured that would be a strange one. On the side of A-8 in bag, there are four items there, and one additional item has been added. The drill core-stem, which we Just labelled as a core tube pole, because it looks like a pole.
CC: Roger. That's the 3-foot core stem.
CDR: And A-9 is collection bag number 3, for 30 pounds.
CDR: B-l, B-2, and B-3 are as you have them listed.
CDR: B-5 is rockbox number l, for 36 pounds; and B-6 is rockbox n,,mber 2, for 40 pounds.
CDR: And then B-5 and 6, B-8, L-2, and L-B are as you had them listed.
CDR: And R-1 is the Flight Data File and LM PPK.
CDR: And then, on the next column, they are all as you have listed. For the top R-2, R-3, and in R-3, we have the entire I_ Data File. And we've taken R-12 out of R-3 and put it in another spot.
CDR: R - far - R-4 is as you have it, as is R-5, R-6, R-8, R-11, R-13.
CDR: Okay. U-1 will only have one temporary stowage bag in it.
CDR: U-2 will have the items listed, plus the accessory bag, in which we have - the contaminated gloves. And I'11 read you a list of those items, if you are ready to copy.
CDR: Have one set of EV gloves and one set of IV gloves, waist the tethers - the - the tethers, paper towels. And I guess that's about it.
CDR: U-3, it's as you have prescribed there.
CDR: Okay, Houston. Ready to go with the right-hand column. U-4 is as perscribed [sic], and R-2 is as perscribed [sic].
CDR: Okay. The PGA bag is as perscribed [sic] with the following additions. First we have - in - in the bag where we'11 put the lunar sample - we'11 have R-12, with the CSM Malfunctions Procedures and Systems Book.
CDR: And the lunar sample is bag number 7, for 24 pounds.
CDR: Okay. And then, everything else is as perscribed [sic]. And the CMl° PGA will be in the sleep re- straint under the right-hand couch with two TSBs, which are now acting as waste containers.
CC: Roger. And that - that location was where again?
CDR: Underneath the right-hand couch, strapped down as - as it's perscribed [sic]. We Just wanted to note that, within that sleep restraint with the PGA, will also be two TSBs.
CDR: And that's Just light waste material in those TSBs. And I guess that pretty much takes care of it, unless you have any questions.
CC: Thank you, Dave. We copy all of that.
CDR: Okay. And, as you go through it and look it over, if you have any questions or anything you'd like us to shuffle around, why, let us know.
CC: Okay. We sure will. Thanks.
CDR: Ro - Roger.
CC: 15, this is Houston. The next several attitudes are going to require us to use OMNI Delta, and we suggest that you go MANUAL and WIDE and stow the high gain antenna.
CMP: Okay. We'11 do that and go to OMNI Delta.
CMP: Understand. Retract the mass spec for 85 seconds.
CC: That's affirm, and then we'11 leave it there for about 5 minutes. We'11 cue you when to extend it again.
CC: 15, this is Houston. Would you please extend the mass spec boom all the way out again.
CC: And I have a T-start for the lunar eclipse photo's when you're ready to copy.
CMP: Okay. Go ahead with the T-start.
CC: T-start for lunar eclipse photo's. 268:59:47. 268:59:47.
CMP: Understand,
CC: Al, we had a question on the mass spectrometer and visual look through the window that it was retracted?
CMP: Negative, Karl. You can't determine that it's retracted. All you can determine is that it's full out.
CC: Roger. Well, when it was retracted, you wouldn't be able to see it. That's what I'm asking. Is it possible for you to take a look now and see if it slowly comes in to view?
CMP: Roger. In other words, you're asking to a con- firm that it does come full out.
CC: Just to clarify our question, Al, the main ques- tion was Just to confirm whether or not it did go out of your field of view. Did it actually move from the full - from the full-extended position? Since we saw no change in the data when we're- tracted it during the test yesterday, there is a suspicion that, even though you actuated the switch, that for some reason it didn't retract.
UNKNOWN: Understand. Okay. It's fully extended now, Karl. But it may be too late. It may have already been out by the time we looked.
CC: 15, this is Houston. We have a rather extensive update to the Flight Plan. And also, a change to the procedure for the contamination of photos, which we can read up to you at your convenience.
CMP: Okay. Does it involve the things going on here in the next couple hours?
CC: It - it's pertinent beginning at 271. We probably ought to get it in before the press conference at 270.
CMP: Okay. Go ahead, Karl.
CC: Okay. If you've got the Flight Plan out, we go over to 271 hours. And at 271:20, Just under S-band OX TV Science, we add V_B 49, maneuver to contamina- tion photo attitude. The attitude is 014, 195, 016; HIGH GAIN, PITCH, minus 23; YAW 252. 173/3 Tape
CMP: Okay. At 171:20 [sic] Just after S-band OX TV Science, VERB 49 to 014, 195, 016, HIGH GAIN, PITCH, minus 25 - 23; and the YAW, 252.
CC: Roger. Just after that, we delete MASS SPECTROMETER ION SOURCE, OFF, and in the space there add configure for urine dump.
CMP: Roger. Delete the MASS SPEC and ION SOURCE, OFF, and configure for urine dump.
CC: Okay. Delete the next one, two, three, four lines, but we - and that brings us to GAMMA - GAMMA RAY, GAINSTEP, SHIELD OFF, which we leave in.
CMP: Roger. Delete four and leave in the GAS_4A RAY, SHIRLD GAINSTEP, OFF. Go. And
CC: Delete all of the rest of that page. add at 271:40, VERB 48, 11101, 01111, and P52, option 3.
CMP: Okay. 271:40, VERB 48, 11101, 01111, and at P52, option 3.
CC: Roger. And at 271:45, we add GAMMA RAY BOOM. D_OY, 4[['_econ_$, _hen-off.-GA_94A RAY, GAIN- center, contamination STEP, anti,start photos.
CC: Okay. 271:45, GAMMA RAY, BOOM DEPLOY, 41 seconds, then off. GAMMA RAY GAINSTEP to center. Start the contamination photos.
CC: And there's a note on the photos that you begin to dump according to the photo procedures, which are - I have an update to that I'11 give you later. And that we dm_p the water to 40 percent, in order to have the right weight at entry. Roger. It's important that we don't go below 40 percent on the water dump.
CDR: Okay. Understand. Dump according to photo proce- dures and the water dump to no less than 40 per- cent for entry,
CC: That's affirmative. On the next page, 272 hours and 00 minutes, we - I - I presume you know that we're not doing the midcourse correction 6. We cancelled the P52 there. And we keep the H2 purge line heater on, but we cancel the P30 external DELTA-V. We cancel the VERB 49 maneuver, we --_ cancel the next one, two, three, four, five, all the way down to the H2 and 02 fuel cell purge, which we keep.
CMP: Okay. Understand. Keep the H 2 purge line heater, cancel the P52, and the set of lines below H2 line heater on, and keep the H2/O 2 fuel cell purge.
CC: Roger. And at 272:28, a note that you should be ending the contamination photos at that point.
CC: 2- 272:38.
CMP: Okay. 272:38, end contamination photos. Go ahead.
CC: Right. At 42 we cancel - we delete the waste-water dump, since we've already done it. And at 42 we add: "Start the mass spec boom test," and the pro- cedures are to be read up in real time. At 58 we cancel the mideourse 6.
CC: At 273:01 we - -
CMP: Okay. At 272:47, that's the - Hold on. Let me read it back. 272:42 the mass spec boom test procedures in real time, and cancel MCC-6. Go ahead.
CC: Roger. At 273:01, we cancel the burn status re- port and we add: "X-RAY experiment ON. ALPHA X- RAY COVERS, OPEN, and record the GET." eXperiment
CMP: Okay. 273:01 X-RAY ON, ALPHA X-RAY COVERS, OPEN, and record the GET. Go ahead.
CC: Roger. At :03 we delete the gamma ray, X-ray, alpha particle, M80, On. And down at 273:47, we add GAMMA RAY, BOOM, DEPLOY.
CMP: Okay. A deletion at 273:00 - or :03, the four items there and then GA_ RAY, BOOM DEPLOY at 273:47. Go ahead.
CC: Roger. And one final item on 274:05, in the MASS SPECTROMETER instructions there, the DIS- CRIMINATOR should be LOW instead of HIGH.
CMP: Okay. 272:04 [sic] MASS SPEC, DISCRIMINATOR, LOW vice HIGH.
CC: Roger. And if you have the time, I can give you the update on the contamination photography, which is on photo 25 and 26 in the back of Volume i of the Flight Plan.
CMP: Stand by l, please.
CMP: Okay, Houston. Let's hold off on the updates of those other photos, so we can get squared away for the eclipse photos.
CC: 15, this is Houston. Your astroncmer CAP COMM is getting curious to know whether you are seeing anything of the lunar eclipse. Anything visible?
LMP: Oh, sure, we've seen it come down to about half to 1/Sth about illumination at the present time, relative to the Sun's illumination.
CC: Roger. And what percent of the disk is covered now?
CC: Okay, Karl. Looks like about 9/10ths of the disk is covered at the present time, and we've been taking the pictures all along. It's a very pretty sight out there.
CC: Roger. Sounds like you are getting close to total eclipse there. Hey, we note down here that in your free mode you are drifting somewhat in pitch and you are about 5 degrees off now. The recommendation is to go auto and stop the drift if you can and cycle back to free before you take your next photo. If there is anything you can do to correct the pointing it might be a good idea.
LMP: Okay. Right now the photos are handheld, so we'11 get to it when we get to the Nikon.
CC: Okay. _
LMP: Houston, 15. The Moon's in the shadow now and we have a variation in color from a almost a light gray to a burnt orange from one side of the Moon to the other. _lmost like the old harvest Moon, except that I'm not sure there's any atmosphere up here yet.
LMP: Houston, 15. We've finished the photos, and A1 had the Moon in the reflex part of the Nikon all the way, so I'm sure the pointing was okay.
LMP: Right now the Moon is sort of - varies from sort of a very pale orange to a good deep burnt orange on one side and a very gradual change. And I hope the - the photos come out because it - it certainly is pretty.
CC: Very good. It sounds like a beautiful view from up there. You've seen a lunar eclipse of the Moon twice as big as anyone else has ever seen such an eclipse.
LMP: That was very interesting, and it certainly is a - a pretty view. It'd be a- a great place for sombody like you to come up and use your trained eye to interpret all this and understand it.
CC: Sounds like it would be fun, someday.
CC: I see you have your E_ entry check coming up. If there is any chance of my slipping in this change of procedure on contamination cloud photog- raphy I'd be pleased to - at this point.
CC: Okay, give us a couple of minutes to reconfigure here. We'11 have time to do that.
CC: Okay, fine. I'11 stand by for your word.
CDR: Okay, Houston. Go with the contamination cloud photography update.
CC: Roger, Dave. Are we on photo 25?
CDR: Photo 25. Go.
CC: Okay, the reason for this change is that we have to use the DAC, instead of the Nikon, since we've run out of Nikon film. The first change is under procedure - l, configure camera; we go down to the second line in the CM 4, et cetera, we - we X that out, and we substitute - CM 4 - -
CDR: Stand by 1, Karl. We want to find out if we have any more Nikon film. We may have some.
CC: 15, Houston. Our records show that you will be out of Nikon film when you finish the lunar eclipse photography, and we'd prefer that you use it for the lunar eclipse.
CDR: Does that include MAG W?
CDR: Oh, disregard that. We just found a - a little note on MAG W, it says "Do not load in camera." I guess that takes care of that. Go ahead with your update.
CC: Okay, fine. The basic specs there in - are - We're using window 4/DAC - D-A-C/18/VHBW-bracket, M-I-R for mirror, PCM pic cable. (Ti, 1/1000, infinity), 24 feet per second.
CDR: Okay. DAC/18/VHBW-bracket, mirror, PCM cable, T1 1/1000, infinity, and 24 frames per second. Go.
CC: Correct. The next line, it's magazine H, maga- zine Hotel, and magazine - and instead of frame number, it's magazine percent to be filled in there.
CDR: Roger. Hotel and percent. Go.
CC: Okay. Completely delete number 2, and substitute instead the following: "UTILITY POWER, on; cover _ lens; DAC, on 2 seconds." Change shutter to "1/60;" Change frame rate to "Time."
CDR: Okay. "UTILITY POWER, on; cover lens; DAC, on "l/60th," 2 seconds," change shutter to and frame rate to "Time," in place of the number 2 you have. Go ahead.
CC: Roger. In step 3, we delete "Inhibit all Jets," and, at the end, we add "CMC NODE, FREE."
CDR: Roger. Delete "Inhibit all Jets," and add "CMC FRW.V? MODE, at the end. G ° ahead.
CC: Roger. At the - at the end of step 4, before "Repeat 4-frame sequence," we write "CMC MODE, AUTO." And we delete "Repeat 4-frame" - -
CC: We - we - we - we delete the "Repeat 4-frame sequence."
CDR: Okay, step 4. Add "CMC AUTO" and delete "Repeat 4-frame sequence." Go ahead.
CC: Roger. Step 5. Instead of T plus 6 plus 6:30, we - It's T plus 3:30, 3 plus 30. Dump waste water - -
CDR: Roger. T plus 3:30 vice T plus 6:30.
CC: Roger. And it says "Waste water or urine," it's really "Waste water and urine ." The - and we dump --
CDR: And vice or.
CC: Go ahead, and - Okay, and we dump to 40 percent as you've been previously advised. Also a part of 5, add "Repeat step 4 (damp rates)."
CDR: Okay. In step 5, add "Repeat step 4 and damp rates." Go.
CC: Step 6, the time there is not 26 plus 30, but it's 28 plus 30. Also - -
CDR: Roger; 28 plus 30 vice 26 plus 30.
CC: Roger. At the bottom, we delete "Repeat 4-frame sequence," and we add the following: "T plus 32 plus 0; CMC MODE, AUTO"; and below that "Repeat step 4 (damp rates)."
CDR: Okay. At the end of step 6, can - cancel "Repeat _-frame sequence," and add "T plus 32 plus 0; CMC, AUTO;" and then "Repeat step 4 and damp rates."
CC: Roger. On step 7, it's "T plus 43" instead of 48; and, at the end, delete "Repeat 4-frame se- quence,'' and add "CMC MODE, AUTO."
CDR: Okay. Step 7 is "T plus 43," and delete the "Repeat 4-frame" and add "CMC, AUTO." Go.
CC: Roger. Step 8. We delete "Enable all jets," and what we record is the magazine percent. And that's the end of the correction.
CDR: Okay. Step 8, delete "Enable all jets," and add percent instead of frames.
CDR: All righty; we'11 do all those.
CC: 15, this is Houston. Sorry to tell you, but I made a couple of errors in that read-up. Can we make it two corrections?
CDR: Okay. Stand by l, please, Karl.
CMP: Okay, Karl; where are the corrections?
CC: It's photo 25.
CMP: Okay, I'm on photo 25.
CC: Right. At the end of step 5 and step 6, I put in a little statement ss_ing "Repeat step 4, damp rates." That's really meant to say, "Repeat step 3," which is "dsmp rates," in both cases.
CMP: Go ahead, Karl.
CC: Guys, at the end of photo 26, when you get through with this sequence, requesting 2 seconds of pro- frame tect also.
CMP: Okay. I - -
CC: 15, Houston. Have a lunar eclipse photo pad on your Flight Plan, page 384, when you're ready.
CMP: Stand by, Dick.
CMP: Okay. I'm ready to copy the photo pad on the lunar eclipse.
CC: Okay. 270:49:53.
CMP: Roger. 270:49:53.
CMP: OMNI Charlie.
CDR: Stand by; we're maneuvering.
CDR: Okay, Houston. Are your high gain angles for the sextant photos or for the lunar eclipse photo attitudes ?
CC: Sorry about that, Dave. When you complete this maneuver, they're in your Flight Plan, FITCH, minus 22; YAW, 227.
CDR: Roger. AUTO and NARROW.
CDR: Houston, 15. You ready down there?
CC: Roger, 15. We're close to ready. Are you ready for the big press conference?
CDR: Roger. We're ready. Anytime you want to go to transmit, let us know.
CC: Okay, you can go ahead to transmit.
CDR: . Roger. Go ahead with your questions.
CC: Roger. We'11 - we'11 admire the beautiful picture for - for a few minutes here. Deke just passed out from the shock, incidentally.
CC: Okay, fellows, I have a preliminary statement to make here. The questions you will be asked in this news conference have been submitted by newsmen here at the Manned Spacecraft Center who've been covering the flight. Some of the questions they raised have been answered in your c_mmunications with - with Mission Control, but the public at large has not necessarily heard them. The ques- tions are being read to you exactly as submitted by the newsmen and in an order of priority specified by them. Question number 1. Since last week, we have shared scores of exciting moments with you. Which single moment would you most like to live again, and is there any moment which you would never like to repeat?
CDR: Well, I guess we all probably have a different idea on which would be the single most exciting moment of the flight, and maybe we'11 Just run through it one at a time. I guess the most im- --_ pressive moment I can remember is standing up on Hadley Mountain, Hadley Delta, and looking back at the plain and seeing the LM and the rille and Mount Hadley, and the whole big picture in one - one swoop. And I think we've got same pictures for you from up there, and I believe the TV was running at the same time, and I think that was probably the most impressive sight that I've ever seen. Al.
CMP: I guess I'd have to say - sort of, two events occurred which were exciting for different reasons, and I guess they were really kind of the highlights of - of the flight for me. One was, right after LOI, when we got our first look at the Moon, and it was a fantastic, spectacular sight. And the other, I guess, was when Tgi burned so beautifully, and right after TEI, that was an awfully good feeling.
LMP: Okay. Well, I guess there were a great many new thrills for me, and the one that was most im- pressive though was the lift-off. It began the flight, and I knew that I w_s going into space after a few years of waiting and training. And then, as far as the event that I would not like to - to repeat again, was probably the time when I fell down in front of the TV when we were deploying the Rover.
CC: Question number 2. Near Spur Crater, you found what may be genesis rock, the oldest yet collected on the Moon. Tell us more about it.
CDR: Well, I think the one you're referring to was what we felt was almost entirely plagioclase or --_ perhaps anorthocite. And it was a small fragment sitting on top of a - a dark brown larger frag- ment, almost like on a pedestal. And Jim and I were both quite impressed with the fact that it - it was there, apparently waiting for us. And we had hoped to find more of it, and, I'm sure, had we more time at that site, that we would have been able to find more. But I think this one rock, if it is, in fact, the beginning of the Moon, will tell us an awful lot. And we'11 leave it up to the experts to analyze it when we get back, to determine its origin.
CC: Question number 3. Apollo 15 is already being described as one of the great events in the history of science. Aside from the crystalline rock, what other findings at Hadley-Apennine seem most im- portant to you?
UNKNOWN: I guess, immediately, I think of the orientation or organization that was revealed in the side of Mount Hadley. There's 14,000 feet vertical relief of vast mountain face exposed to us. And there was layering in there that was most impressive for the total 14,000 feet, and we commented on the number of beds we could see. That really impressed me, that you could have that much organization in - on a large mountain on the Moon.
CDR: Well, I think, to begin with, we had every con- fidence that we could get to the landing site. The trajectory had been modified such that we had ade- quate clearance over the mountains. And the first sight I had out the window was somewhere around probably 9 or 10,000 feet as we passed down below the upper elevations of Mount Hadley. And I could see Mount Hadley to my left before we pitch - pitched over and saw the - the plain at Hadley, and that was probably as impressive sight - a sight as I've seen. The landing itself, once we pitched over, was somewhat of a surprise in that the - the craterio_ was much more subtle than we had expected. There was a great lack of any large fragments or boulders on the surface. It was ap- parently quite smooth, and those rather deep craters which we had anticipated using as landmarks because of their subtlety did not appear quite as readily as we had hoped. I think we did recognize our relative position east-west of the rille be- cause of the size of the rille itself. I think we were a little off on the north-south, but close enough to handle the traverses in the Rover. I think that having a vehicle such as that - as that enables us to go into more cGnplicated, difficult landing areas because it's not necessary to land on an exact point. We can take advantage of our mobility and land anywhere within a certain prescribed area which was initially our goal on this flight.
CC: Question number 5 for A1 Worden. In lunar orbit, you too carried out geologic observations; for example, you reported cinder cones. Could you discuss this and other observations from 60 miles up?
CMP: Yes. The c_mment on the cinder cones was one df color, but we noticed particularly on - on some of the lighter part of the back side that many many of the craters that we flew over were filled with what appeared to be lava. There seemed to be a great number of lava flows in the - in the mare area, particularly Mare Imbrium. Mare Imbrium -- seems to be a- Just a - countless numbers of - of lava flows, which were all apparently very thin and very fluid. And you can see - you can just count number - numbers of flow fronts covering Mare Imbrium. So we got, I think, quite a distinct impression of a - of a - of a great deal of vol- canism around the Moon. And, in same particular isolated area such as the Littrow area and such as areas like probably the Aristarchus Plateau, there's a great deal of volcanism and some cinder cones and - and certainly a lot of lava flows.
CDR: I think anytime you set out on a task such as the one we had, you're bound to, at certain times, get a little tired, which I think we probably did. However, I think we came back and I don't think we ever reached anywhere near the limit of our physical endurance. I think Apollo 16 probably has everything in hand; it's Just a matter of conditioning yourself. Jim and I have discussed it since we got back onboard the Endeavour and concluded that our training is what really pre- pared us, and the many hours we spent during geology field trips and in simulations at the Cape in our suits, we feel, was the factor which really contributed to being able to proceed with those duration EVAs. I see no problem in the future with conducting three successive 7-hour EVAs. Neither one of us were particularly physically tired. I think the fatigue is really in the - the mental regime, in which you're concentrating very intensely for 7 hours, and you're pressing to do your best all the way through and - and keep your eyes open to make the appropriate ob- samples. servations and gather the And I think it's really more of a mental factor than a physical factor.
UNKNOWN: Well, there were several times there when we were riding along where we'd hit on a sizable bump and you could - you could see the - the wheels come off the ground and then float through the air and - But Dave should c_mment more as far as the - the driving. And it was really like a bucking bronco, that's true, because I was strapped in. As you know, Dave had to strap me in because I had some trouble with my seatbelt, but I - I really did feel like I was on a - a bucking bronco.
CDR: I think I might add that it's a - it's a very stable machine, but because of the - the 1/6th gravity, it tends to float. In - in the simula- tions we ran in Houston, we saw the same amplitude or the same degree of bouncing but a different damping. In other words, the - the vehicle would come off the ground, or one wheel normally would come off the ground, and it would take it some- what longer to return to the ground than in one g. And I think it's Just a matter of being - becoming accustomed to the to - driving. It's a very stable vehicle; the suspension system - system is excel- lent. We had to make some rather sharp avoidance turns periodically, and in - in these turns, we could tell the vehicle was quite stable. No tend- _ ency to turn over whatsoever. I think the only recommendation we'd really have would be to come up with a new idea on the seatbelt-type arrange- ment, and we -we've discussed that also. I think we have some suggestions we could make when we get back to ensure that you can have both crewmen securely in their seats in a short period of time. Other than that, I think the vehicle is about as optimum as you can build.
CC: Question n_mber 8 for Dave Scott. The drill seemed to drive you up the crater walls. What was the problem, and was it worth the time?
CDR: I guess I'd anticipated that question. I think the problem was a - a striking discovery. When we went to Hadley Rille, we expected to find a regolith, or the soil, about 5 meters thick. And with that in mind, like 25 feet, I expected to have no trouble putting the heat flow probes in or dril- ling the - the core stem because of the expected soft soil. After about 1 meter, I ran into hard rock, and my first thought was it was an isolated rock somewhere within the - the soil. But that was not the case. Apparently, what we have is a very thin regolith or a thin soil layer above solid rock. And with this in mind, I think we brought back a core stem or a deep drill-core of the Moon of basic bedrock or foundation rock on Hadley Plain. I think that's a very significant find. I think it will be very meaningful to the scientists when they analyze it. The perplexing problem was doing the actual drilling and extracting the core stem. If you put a drill into solid rock, it's very diffi- cult to get it out, And there at the end, it took both Jim and I with our shoulders pushing, as hard as we could, up - to extract the drill stem. But in the final analysis, as I look back on it, I think it is indeed worthwhile. At the - at the time it occurred, we were both interested in mov- ing out to the - the Northern Complex and further geology, which Jim and I are both quite interested in. And the mechanical task of doing the drill at that time seemed what - somewhat less important than seeking new - new finds in a new geological area. But, in retrospect, I think we have, in fact, brought back one of the most significant samples of the whole trip.
CC: Question number 9 for Dave Scott. In view of your comment to geologist Leon Silver about the need for trained scientists on the Moon, do you think that scientist-Astronaut Jack Schmitt should be included in the crew of Apollo 17, the last of the Apollos ?
CDR: Well, since I really have very little say-so as to which - which people get selected for which crews, I might sort of bypass it with a - with one com- ment that I think the more qualified a man is on the Moon, the more results you're going to get. And I think that's one of the reasons that we put as much time as we did into the geological aspects, in hopes of - of learning enough to bring back some significant data. I think that in any situa- tion such as this, in any scientific endeavour, that you want the most qualified people possible. You must also remember that this is a - a highly complex operational mission. It requires a great deal of - of training and skill in order to fly these machines. I think, in particular, Jack Schmitt is a very highly qualified individual in both as- pects. And I believe it's up to the - the manage- ment, that when they select the crews, to select the best people for the flight.
CC: Question number 10 for A1 Worden. What runs through the mind of a man orbiting the Moon alone?
CMP: Well, I guess - I guess the - the thing foremost in nV mind during those B days was how I was going to keep up with the time line and the Flight Plan, and how I was going to keep track of all the ex- periments we had going and where they were, and - and whether they were operating or not. And I guess that was a very, very fast B days for me. When I wasn't looking at the SIM bay experiments, I was looking out a window and taking pictures, and it was a pre_tty cr-mmed 3 days. As a matter of fact, I - I guess I didn't really have - have much time to give any thoughts to being alone up there.
CMP: Well, let me answer the last one first. I - I guess I didn't come in soon; I came in when the And, Job was done. as a matter of fact, I made an extra trip back out to take a look at the map- ping camera. Now as - as far as what I felt like when I went out there, we talked a little bit about if after - after the EVA and decided it was sort of like walking on stage at your high school - dinner dance or something. We opened the hatch and it was pitch black, and as soon as we got out, the Sun was beating down on everything, and it looked like a very lamge floodlight on a stage. And then putting the TV camera out on the door just added a little bit more to that sort of un- real feeling that it was time to get out on the stage and do something. I think, as far as the EVA went, we did it Just almost exactly as we'd practiced it. It took almost exactly the same amount of time; we did it the same way. And, of course, we had practiced that with pan - with the mapping eaw_ra in the extended position, and so that - that really posed no difficulty to us.
CC: Question number 12 for Dave and Jim. You - you didn't have time to get to North Complex, craters which m_y have been formed volcanically and where you thought some surprises might be found. Was this a significant loss?
CDR: Well, I'11 start out and - and throw an answer there. I think if you look back at the original requirements for the landing at the Hadley- Apennines, they were primarily to inspect the front and the rille. It was only after a - a consider- able amount of study had been done and some re- arrangement in the Flight Plan - the timing on the surface, found that we we had enough time to plan to go to the Northern Complex. So the Northern Complex was, in fact, an addition to the original requirement; it was bonus. And I think because Jim and I have spent so much time with volcanics in our terrestrial geology work, that we were quite interested in getting to the Northern Complex to 174/13 Tape see if, in fact, it was a volcanic area. But I don't believe we lost anything from the lunar sur- face by not going there; only we would have had an extra bonus had we been able to reach that point. And, with that in mind, I hope that some day some- body gets a chance to go back and take a look at the Northern Complex. Jim, do you want to answer?
LMP: No, I agree with everything you said. It was just a little personal disappointment that we couldn't get up there, because we - we thought we'd have another beautiful view of the - the plains there and the I24, a view Almost as beautiful as it - as it was from the side of Hadley Delta.
CC: Question number 13 for each of you. Would you, gave please, in your own words, tell us what you the American taxpayers besides a few hours of good television?
CDR: Well, I think - the magnitude of the scientific data we return will speak for the taxpayers' money. The small amount of time they had for television, I think, is rather insignificant relative to the amount of return we've gathered in the SIM bay and in the lunar samples we have aboard right now. I enhance think these data will not only en - the progress of science, but it will reach the common man on the street directly by the - the byproducts of what we learn. I think man must extend himself, the new frontiers must be open in order for us to - to propagate m_nkind, and I think this is one way in which we do it. I - I feel that the taxpayers got, probably - as a matter of fact, I hope they got more than their money's worth out of the flight. And, if you could see the size of the film maga- zines that A1 brought in yesterday from those ca- meras, why, you'd see that we have indeed at least on a great deal of data film alone.
CMP: Well, I really guess that there's not much to add to what Dave said. He - he expressed my sentiments exactly, in that the - the knowledge that, hopefully, we've - we've added to our store of information about the Moon and about ourselves will be increased in an extent which is greater than - than the - than the capital that was - spent on the flight itself. And I would certainly think that - that the full theory adds significantly to - to man's knowledge about h_qelf primarily and about h_m_elf in those areas where it will help future genera- tions maybe. -_
LMP: I can only add that we're bringing back just a lot of - lot of data and a lot of material, and it's going to take many years for people to really appreciate how much was gained from - from this flight.
CC: Question number 14. It seemed this flight has as many problems as some of the old Gemini missions. Which of these gave you the most concern; and, for Dave, did you ever feel you were back on Gemini VIII?
CDR: Well, I guess we weren't aware we had that many problems. I thought this was a rather trouble- free flight, myself. We went a long way, we spent a long time doing the Job, and I think, relative to the number of systems we have in all the space- craft, that we had very few problems. I can think of none that were significant that would enable me to compare it with Gemini VIII at all. We had a - I guess the first little problem we had was a - a leak in our water system, which was cleared up rather rapidly by somebody having already done some investigation and having a procedure at hand. I believe our system is such that people have all the anticipated problems understood, and, when they have them understood, they come up with solu- tions which are quite meaningful and successful. And I feel like the spacecraft and the life-support systems on the Moon and everything worked exceed- ingly well. I - I guess really I couldn't ask for much more. How about you?
CMP: You know really, we had very few problems. It seemed like a very tame simulation, as far as I was concerned. Certainly, there were - there were - there were irritating things that happened like some circuit breakers in the spacecraft here that gave us some trouble, and some lights that aren't working exactly right. But certainly none of the important aspects of the flight or - or none of the essential pieces of equipment have malfunc- tioned, and I think it's been just great. 174/15 Tape
CC: Gentlemen, we'd like to continue the press confer- ence in a few minutes. But, in the meantime, we'd be anxious to get - start - get one of you started on the lunar eclipse photos. We have three more questions. Question - -
CC: Question number 15 - for Dave and Jim. How many times did each of you fall down on the lunar sur- face? Did any of these falls hurt you or give you any problems?
CC: Well, I fell down twice, and it was never any real problem. Actually, I could have got up very well by myself without any help.
CDR: Yes, I guess I fell down twice, too, and, as Jim said, it was never any real problem. It's a matter of if you start to go - and, of course, the terrain there, I guess you could see in the television, was quite rough and irregular with occasionally rocks around, and we were pressing to try and get things done. And it was Just a matter if you Just start losing your balance, to go ahead and go easy, and accept somewhat of a - a light fall. Because of the 1/6th gravity, there was never any impact when we hit. Take it easy and get up slow. And I don't think either one of us ever came anywhere near the point of being hurt, in that sense of the matter, it's Just a matter of slowing you up for a minute, enabling you to re- gain your balance, and go ahead. And I - I have a question. Do you want to have the photos of lunar eclipse with the television now, or do you want us to get on with the - tha camera photos? Because if that's the case, we have to turn the lights out in here.
CC: Roger. We're going to skip down to the last question, Dave, which says your cabin must be Jammed with Moon rocks, core samples, suits, and assorted hardware. Can you show us what it's like in there? And, as you show us around, you can get set up for the Moon photos and dim the lights when you like.
CDR: Okay. I guess to show you around, we have to un- stow everything. We're - we're pretty well stowed for reentry right now. We have all the samples stowed, the suits are all stowed, and I guess, in _-_ order to show you around, we'd have to do some unstowing because under - beneath the couches right now, it's Jsmmed full. And I guess we'd like to do that for you, but it's some - somewhat imprac- tical, in that all you can see would be some edges of some white bags, and that's why we have the room in the cabin here. Every - everything's pretty well squared away. Hut, when we get back, I'm sure you'11 have an opportunity to see the many things we have, and there's really a lot of it.
CC: 0 - okay, Dave. That's fine. And I guess one last request is when you get over to that window to - and before you take the photos, could you give us a quick picture of the Moon with the TV camera?
CC: 15, the word here is to proceed; give your photog- raphy first priority there, and maybe we can see the - the Moon out of the other window.
CDR: Okay. We' re working on it.
CDR: Okay, Houston. I think you have a picture of her now. There she is.
CDR: Oh, really? I've got a good picture on the monitor.
CDR: Roger; that's right.
CC: 15, Houston. We'd like to ask if you've got full zoom there?
CDR: Roger. It's all the way out.
CC: Could you please give us ALC to PEAK?
CDR: I think we are; Just stand by 1.
MCC: Hello, Endeavour; this is Yankee Clipper. Over.
CDR: Hello, Yankee Clipper. How are you?
UNKNOWN: Roger. I've got a naval tradition to pass on to y OU
MCC: Roger. when ships of the line have completed a mission such as yours and they return to home port, they alwaYs have a broom flying from the yardarm. Over.
CDR: Roger. Well, we'11 do that.
MCC: Thank you. wouldn't want
CDR: We to break any traditions, Dicky.
UNKNOWN: I'm watching you; I wouldn't let you.
CDR: That a boy, and I'm glad.
CDR: Okay, Houston. We're going to switch windows herewith the TV camera, so we can switch windows
CC: 15, Houston. When somebody gets a free hand up there, could we start the charge on battery A? We're afraid that might keep us from going to bed if we don't get it started soon.
CDR: Houston, the Moon is an orange ball, now - a dull orange ball with a sort of a gray area in the cen- ter on - on one side opposing the side that's illumination slowly coming into at the present time, and you'11 possibly get more and more of the lunar surface exposed to sunlight as we go along here. The picture you have is really pretty good for what we see, because there's very little illu- mination on the Moon. And only when we get the and cockpit lights down reasonably low get our face up in the window can we see the definition. So it's really not a bad picture.
CC: Roger, 15. Thanks for the description, and the picture we're .getting down here is quite good also.
CDR: Okay, I'm sure you'11 have a much better one here in a few minutes.
CC: Apollo 15, Houston. Over
CC: Roger. It looks llke you've had enough of the pho - photographY for right now. It's beginning to get pretty bright on the tube. I guess we can go ahead and power it down.
CDR: ·Okay.
CDR: That's interesting, Houston, because it looks like only about - oh, maybe 1/20th or so, maybe, of the Moon is illuminated at this time; Just a thin sliver, but very bright.
CC: Apollo 15, Houston. Request S-BAND AUX to SCIENCE, please.
CC: Roger, Apollo 15; go ahead.
CDR: In getting ready for the contam_uation photography, we find that we've got a - a certain number of exposures left in the Nikon. Namely, we're on exposure number 29 in MAG Victor, and we think we have 45 total, which would enable us to complete the contamination photography with the Nikon, if you desire, rather than with the DAC, as you changed.
CC: 15, they plan on using those last 15 frames or so on Victor for postmission callbration, so we still intend to press on with the DAC, please, Dave.
CDR: All right, understand. Thank you.
CC: And, Dave, if you give us a start time on that, I'11 give you a call at the end, because we want you to cycle some extra film through the DAC to give them a little leader there at the end to protect their film or something.
CDR: Okay, we'11 do that. Stand by.
CDR: Go ahead_ Bob.
CC: Roger. We were seeing the OPTICS tripped around against the hard stops. We'd like to have you bring them back and then zero them in, per the usual procedure. We kind of guess you're getting ready for 52 anyway, aren't you?
LMP: Pretty soon.
CC: And, 15, we have your torquing angles. You go to _-_ torque.
CDR: Roger; in 30 seconds.
CC: Apollo 15, Houston. If one of you guys is free, we've got some updates we could read to you.
CDR: Okay, Houston; 15. Stand by 1,
CC: Okay, understand you're ready. What - The first thing is an entry pad, so you might whip out your Entry Checklist.
CMP: Okay, Houston; 15. Go ahead and ... from that.
CC: Roger. Would you believe it, we're going to land in the mid-Pacific? And after that, it's 000, 153, 000; 294:41:37, 267, plus 26.12, minus 158.10; 06.2; 36097, 6.50; 1084.8, 36179; 294:58:37; 00:29% NOUN 69s are NA; 4.00, 02:13; 00:18, 03:38, 07:44; 04, 140.3, 37.5; 213, down, 09.6, right, 4.7; lift vector, up. Comments: (1) use nonexit EMS pattern, (2) RET of 90 K, 6 plus 06; RET of mains, 8 plus 32; landing, 13 plus 29; constant g, roll right; moonset time, 294:56:20. Over.
CMP: Okay, Houston. Understand. Entry pad, mid-Pac; 000, 153, 000; 294:41:37, 267; plus 26.12, minus 158.10; 06.2; 36097, 6.50; 1084.8, 36179; 29_:58:37; 00:29; 4.00, 02:13; 00:18, 03:38. 07:44% 04, 140.3, 37.5; 213, down, 09.6, right, 4.7; lift vector, up.

CC: Roger, Al. Good readback. And We'd be interested in knowing the status of the EMS check you ran 2 or 3 hours ago, if you have it.
CMP: Yes, sir. The EMS check was just fine.
CC: Okay, that's good to know. At the end of your contamination experiment here, we'11 be going into this mass spec boom test. And, if you guys let me know when you're ready, we've got a procedure to read up to you for that - that we'11 read up to you at that time. I assume you've been told that we aren't going to a midcourse 6, and right now mid- course 7 is looking like .09 which is - makes it kind of problematical as to whether we burn it or not. Weather in the recovery area is currently predicted to be, for your splashdown, 15-knot winds, 4-foot seas, 2000 scattered, 10 miles- In other words, looking better and better all the time.
CMP: Roger, Bob; that sounds great.
CC: Apollo 15, Houston. If you'11 give us ACCEPT, we'11 give you a very slight clock update to sync you for entry. And be advised we will not be sending a state vector up-link at this time; your vector is still just as good as the one on the ground.
CDR: Roger; understand, and you've got ACCEPT.
CC: 15, your computer.
CC: 15, Houston. Request you trim back to the original attitude now.
CC: And again, if one of you has a couple of minutes, we can tell you a couple of other things.
CDR: Okay, in - in other words, you want us to maneuver back to the original attitude, rather than just damp rates, huh?
CC: Roger; yes. We'd like to use the same star back- grounds; so that means going back to the original attitude in the Flight Plan around 271:20 or so -
CC: Which is what you got called up.
CDR: No, we don't have that called up. All we have is damp rates, but we'11 do that. Oh, what we have called up here? Yes, okay.
CC: And, 15; Houston. If one of you has some time, we'd like to talk about some stowage, please.
