LMP: I'm not sure what we had when it started. I Just noticed the streRming. I don't think it was on very long.
CC: America, Houston. We need - we could use the HIGH GAIN now, NARROW and REACQ. APOLLO 17 AIR-TO-GRO0_'D VOICE TRANSCRIPTION
LMP: Yes, I'm having the same problem there - I noticed the same problem. How's this, leave it in WIDE?
CC: America, Houston. We'd like you to go to REACQ now, wait 30 seconds, and then go to NARROW.
LMP: Thanks for timing 30 seconds for me, Gordy. I think that was beyond me.
CC: No, it sure doesn't. Stand by l, and we'11 give you an alternate plan here.
CC: Once you get the antenna locked on in NARROW it will track back to this attitudes and that's what we'd like you do is come back down to this attitude, once you get the antenna locked on.
LMP: Okay, Gordy, we got a good lock now.
CC: Okay. Fine. Well, then go right on back to the program pitch attitude there, and it should hold.
LMP: In work - in work.
CDR: Okay. What do you want at 230?
CC: Okay. Basically what we're going to do is turn the IR ON with the COVER, CLOSED, to keep it warm so you can do that IR, ON, now. And then we're going to put out the HF antennas and listen to HF getting some data on background noise from the Earth. If you'11 put HF ANTENNA 2 to EXTEND, we'11 give you a cue when to go OFF when it's all the way out. Over.
CDR: Okay. HFANTENNA 2 to EXTEND on my MARK.
CC: Okay. We'd like HF ANTENNA 2 to OFF, please.
CC: Okay. It probably isn't out yet. The reason we had you stop was because the recorder that's watching that broke down, down here. We got to get that back on line. 173/3 Tape
CDR: Okay. can
CC: While you're waiting there, I go over the foot- ball scores for the weekend, if you wish. I24P Just a minute. Let's see if we can get Ron on a headset.
LMP: He' s walking - he 's walking around here thinking he doesn't have to do anything any more after that EVA, but we'11 get him back to work.
CMP: Okay, Houston. We're ready for those scores now.
CC: Okay. Just i second, Ron. I think we've got another switch for you here.
CC: Okay. We'd like to take the sounder HF ANTENNA number i switch to EXTEND. We'11 let the motor on 2 cool off. We do have the recorder fixed, so we can watch 1 now.
CMP: Okay. Number 1 is going to EXTEND. 3, 2, 1 -
CC: Okay. I've got the whole list of scores here; some of these were yesterday you probably heard of, but I'11 just go through them all. San Francisco beat Minnesota, 20 to 17. Miami m_e it, I guess 14 straight, 16 to 0 over Baltimore. And Buffalo beat Washington, 24 to 7, how about that? Cleve- land beat the Jets, 26 to 10. Kansas City beat Atlanta, 17 to 14. Green Bay won over New Orleans, 30 to 20. St. Louis beat Philadelphia in a close one, 24 to 23. Denver beat New England, 45 to 21. Detroit beat the Rams, 34 to 17; and Oakland beat the Bears, 28 to 21. And here's some sad news. The Giants beat Dallas, 23 to 3. And one final score - Cincinnati, 61, Houston, 17.
LMP: Over. Gordy.
CDR: Gordo, we - don't have any contact - comment. All three of my teams lost today.
CMP: And I'11 turn the switch to OFF, if you want.
CC: That's affirmative. OFF on i and then on 2, we'd like you to go to RETRACT' for 10 seconds, then put her in EXTEND, and we'11 watch it.
CMP: Okay. RETRACT, 1, 2, 3, 4, 5, 6, 7, 8, 9, and about 10, I guess. Okay, then I'm going to -
CC: Okay. We'11 take number 2 to OFF, please. And we're going to let the motor cool down for 15 minutes so you got at least that long until the next time we bug you.
CMP: (Laughter) Okay. It's OFF now.
CC: What we want is you to go to RA_RACT for 10 seconds, and then: EXTEND. C_ 0_ay. Wait 1.
CMP: Okay. RETRACT. There's 10 seconds. Back to EXTEND. 173/5 Tape
CC: Okay, and wa're Just wondering where you stood on the post-EVA checklist procedures.
CMP: Well, probably about 75 percent through. -What we're doing is stowing all this stuff out here, and then we're going to go back through and check things off.
CDR: Gordy, did our little waste-water burn there hurt us or help us?
CC: I guess we haven't been able to determine yet.
CC: Okay. HF 2 ANTENNA, OFF.
CMP: Okay. It was OFF, when you called.
CC: I guess the motor is - -
CDR: And, Gordy - - ...
CC: - - just about stalled out. Doesn't seem to be much - mAking much - much progress there, so - Go ahead.
CDR: I was just going to say we took time out here to grab something to eat, cause it's been a long time between breakfast and lunch so a - I will try and do a little inventory here and give you a page and let you know about where it is.
CC: Okay. We're not intimating there's any hurry. We just were curious.
CC: Okay, a little more amplification on that antenna. The motor gets hot and it starts - slows down and stops making progress. But each time we make a little more progress to getting it out, and we're aJunost all the way. We're going to give it another cool-down period. We'11 give you a call when we want to try it again.
CC: I do have a bunch of short Flight Plan updates, none of which is very close in the future. So any time someone has nothing to do, I'11 be glad to read them up.
CDR: Okay. Let's eat for a little while, Gordy.
CDR: Is it still sunny and cold back there?
CC: That's affirmative; it was clear and - were you talking about the Houston weather? Or the SIM-bay weather? The SIM bay's getting cold, also. It's cool, but it was sunny here today. It'11 probably be a cold night since it's clear.
CMP: You want to go RETRACT first, then for 10 again?
CC: That's affirm. Ten seconds RETRACT, then EXTEND.
CMP: Okay. Going to RETRACT and OFF.
CC: Okay, Ron, it's getting out there inch by inch, but we got to back off and hit it again. Go to RETRACT for 10 seconds, and then back to EXTEND.
CMP: Oh, okay. I went to OFF there for a second, and I'11 go to RETRACT now, and then to EXTEND.
CC: Okay, Ron, go to OFF, and it'11 be another 10-minute wait.
CMP: Okay. We're OFF.
CC: Okay. I guess everybody is in agreement. Go ahead and high gain should stay on during this maneuver.
CC: Is it getting cool up there?
CDR: Well, I'm freezing something off.
CC: Hey, we got a little procedure to warm things up in the cockpit, if you'd like it.
CDR: We - we heard that earlier, and we're passing on that right now.
CC: Was it the one about turning INVERTER 3?
CDR: No, we didn't hear that one. Why don't you tell us what that one is.
CC: Okay, Cernan, put INVERTER 3 on MAIN A. That will put some heat load into the system, and then GO to MANUAL on the TEMP IN valve. Go down and adjust the EVAP OUT temperature to 59 degrees - make it 55 degrees, 55 degrees. And that should help MaNn things up.
LMP: Okay. We'il let you know if we give that a try and, Gordy, I guess we're ready to copy some of those Flight Plan updates.
CC: Okay. Fine. We'11 keep an eye on the TEMP OUT so that - let you know if the - it's getting away. Let's see - let's start on - Stand by 1. Start on page 375 at 263 hours.
CC: Okay. Down at 263:40 where it lists the Jets to use for spinup or for damping, rather, we're going to change the jets to be used for damping, since those ones listed didn't work so hot last night. Want to use all of quad Delta. Delta l, 2, 3, and 4 and Charlie 3 and 4, those six Jets in place of the ones listed.
CC: Okay, and Just to the left of that box delete "IR COVER, CLOSE" and "IR, OFF."
CC: I guess - delete the deletion. I Just got a call since turn the IR ON. We want to turn it OFF at this time, so leave the IR, OFF, call as is.
CDR: You want - you want to delete COVER CLOSED, but - but leave IR, OFF, in, huh?
CC: Yes, the cover is closed, and we want to turn the IR OFF, at that time.
CC: Okay. Turn over two pages to 265:20, and make the same Jet changes for that PTC rate damping, all of quad Delta and Charlie 3 and 4.
CC: Okay, then turn over l, 2, 3, 4, several pages - let me find the next one here. It's ou 275:10.
CC: At 275:10, add "Charge BAT A." 173/9 Tape
CC: Turn the page on 276:25, delete "IR, ON." Then down a few lines at 276:45 delete "IR COVER, OPEN, before dump," and a few more lines at 276:57, delete "Charge BATTERY A."
CC: Okay, turn over two pages to 279:05, and change "
LMP: don biomed harness" to "
CDR: don biomed harness." 279:30 - change - check
CDR: to - check LMP. Change that to "Check CDR" and then make it "
LMP: doff biomed harness."
CDR: Okay. I - I got those, but that's sort of slight- ing the CMP.
CC: Okay, we'11 consider that. Go on to - -
CDR: That's harness - that's harnessing the commander.
CC: (Laughter) Roger. Okay; let's go to 285:10.
CC: Okay. Right after the ¥,:ltB48 add three steps, number i is "RADAR, OFF." Number 2 is "HF ANTE_q1A to RETRACT (OFF, ON STDN cue)." And the next step is the same for ANTENNA 1. "HF ANTENNA 1, RETRACT, (OFF, ON STDN cue) ."
CDR: Okay. RADAR OFF, HF ANTENNA number 2 RETRACT OFF, on STDN cue and the same for number 1.
CC: Righto, and then same page, 285:30, "IR COVER, CLOSE." Delete it.
CC: Next page, 286:25, "IR COVER, OPEN," delete thaz. And on the next page, 287:13, "IR COVER, CLOSED" and "IR, OFF," delete both of those. And a little further down the page it says "
LMP: doff biomed harness." Change that to "
CDR: doff biomed harness."
CDR: Okay. I got those.
CC: Okay; next page is another PTC spinup, same change, "Delta l, 2, 3, and 4 and Charlie 3 and 4" instead of the listed Jets.
CC: Okay, and then backtracking for one last one that was Just handed to me; go back to 263:53.
CC: And the high gain antenna angles; change them from a "-40 and 90" to "20 and 180."
CDR: Understand; plus 20 and 180.
CC: That's affirmative and that completes the list.
CDR: What about 285:30 on the Jets?
CC: I asked the Same question, I think. Let me turn to it here. Yes, that one is a - Just a short - a short run on it and they Just as soon as it wobbles a little so they can leave those Jets the same. That's for a UV scan.
CC: Okay. HF ANTENNA to RETRACT for 5 seconds, and then EXTEND, please.
CDR: Okay; for 5 seconds. Going to EXTEND -
CC: Hey, good work. It finally made it out. Put it OFF, please.
CC: Okay. And then got some more steps here, as soon as I find them. Okay. LUNAR SOUNDER OPERATE switch to STANDBY. That's a verify. Then RECORDER, ON.
CDR: Okay. OPERATE is verified in STANDBY, and RECORDER is ON.
CC: Okay, and RADAR switch, ON.
CC: Okay. RECORDER, OFF, and MODE, HF.
CC: Okay. That does it. We'11 let her tick away now for a while. Thank you.
CDR: I don't believe it. (Music) (Laughter) Got a tissue? (Laughter)
CMP: Exactly what I was trying not to do. (Laughter) (m sic). 174/1 Tape APOLLO 17 AIR-TO-GROUND VOICE TRANSCRIPTION
F: 17, Houston. This is FLIGHT. Gordo's in the back with his family. Go ahead.
F: Okay; copy.
CMP: Okay. We'11 get to it here. Just a second.
LMP: Say, Gordy; this is Jack.
CC: We'11 take a look. Stand by. Give us your best guess on how long ago it was.
CC: America, HouSton. Request the VERB 48 shown in the Flight Plan now.
CC: And we're - we're rechecking on the EPS data. A first glance shows it solid, but we're not sure if it might have been static during that time. We're taking another look here.
LMP: Gordy, don't make a big deal out of it. It may have been just my imagination or somebody hitting the floodlight switch, but it - we tried - I - Gene tried that again, and it didn't seem like what I saw. It was Just a very quick blink in the lights.
CC: Okay. We'11 - we'11 still chase it down.
CMP: Okay, Gordy. How's the old trajectory looking these days? second. However, they're not in a period right now of real solid,track, I guess, and - so it - it'11 take them some more hours to get a really good handle on it.
CC: Nobody predicts any more maneuvers until mid- course 7 at the earliest.
CMP: What would it be at the latest?
LMP: I fail to understand why all my friends who used to operate the backroom, even though it's Sunday, why they haven't given you a sort of an interim report on what they - what they think happened at Taurus-Littrow. They usually have those things available.
CC: Well, I did - you mean, the whole geological sugary?
LMP: Well, Just the general thing that they pass around after a - a day or so, I think, is the time frame they work in.
CC: Yes, there has been such a thing that I think you're referring to. I guess there's a more formal ver- sion coming that's supposed to be due out tomorrow morning, but there was a summary, fairly lengthy, on entire science, including the field geology, you wish. Over.
LMP: Well, I don't need a lot. I guess it might be use- ful to have a general summary maybe tomorrow morning some time, if we have some time in the Flight Plan, of what people have seen up to date on things that we wouldn't normally be familiar with for - in preparation for that press conference tomorrow.
CC: Okay. Sounds like a good idea. On the - your gravimeter questions, the TGE numbers for the com- parison I believe you wanted, between the north and the North Massif and the Sculptured Hills, just aren't available. The whole TGE team took their data and - and left town, evidently. And - we - we have been unable to come up with any good numbers on that question. The lunar surface gravimeter - Okay, break - break here. We need a VERB 48 load as shown, and then - -
CC: Oh, okay. So you can go ahead and do the maneuver then. On the LSG, still no positive success. They've sent just about all the commands it can take with no luck at leveling the beam, and so they've decided to fall back and the whole team is regrouping to consider further course of action. They've turned off the command system to it until some time tomorrow when they'11 try again, evidently, with whatever they come up with in their conference. Over.
LMP: Okay. We're certainly pulling for them, of course.
LMP: Gordy, do I have it straight, that it, apparently, it's a problem just in the leveling commands, or is it - it is receiving other commands, is that correct?
CC: That's the impression I have. I hate to - to say yes certainly. My impression is that it just won't - won't level. It - it will accept commands, but the beam will Just not level for a - a reason that they just don't fully understand.
LMP: Okay. Does that mean that you might - Maybe you could ask Bob when you see him or something - does that mean the beam is not free, or is it not level?
CC: As I understand it - Stand by 1. 59 the problem. (Laughter) Evidently, it's the two plates betweenwhich the beam itself is suspended are adjustable, so that - by ground command, so that by driving these plates back and forth, they try to center the beam between them. And then the - the data is initiated. When the beam vibrates be- tween the plates, it changes capacitance, or at least that's the general principle. And the problem is that by drive, they can comae-nd the plates back and forth and stop the stop, but they cannot get the beam to leave - leave one of the plates. It Just is hung up agains$ one plate, and this would - could be caused by one of the wires that's sus- Pended - sort of hang the beam, pendulum-fashion, being broken so that it has cockeyed off to one side. I guess that's the best guess as to the malfunction at the moment. It's presently in use as a seismometer returning data in that mode, but useless in its prim-wyintended data-taking mode. Over.
LMP: Right. Did they see the beam leave the plates at all as I shook it there near the last of our third EVA?
CC: I guess the answer to that is "no." They saw you Jostling it around and could tell where you were from the data but have no evidence that the be_l_ ever moved from the one plate. any
LMP: Isn't there possibility that the telemetry is giving them a f$1se indication of not leveling - or not centering, I guess, would be a better word?
CC: No, Jack. Evidently, they've eliminated that pos- sibility. They're certain it's a problem - a mechanical problem.
LMP: Okay. 174/5 Tape
CC: Jack, reference your - the blink you noticed or possibly noticed - we, looking at the data, see about BO seconds prior to the time we think you mentioned that it happened but that's close to the time frame, I guess, a i or 2 amp oscillation in the main B voltage or current. And it only lasted for one or two data cycles, or like O.1 or 0.2 of a second is all. We would like to know, though, approximately what setting all the floodlights are at rightnow.
CDR: LEB are full BRIGHT, and the left hand are about three-quarters, right hand's about three-quarters. Jack's the only one who saw that. We didn't - Ron and I didn't see anything on that one, so if it - if it happened, it was awful quick.
CC: America, we'd like H 2 tanks - H2 tank i FANS ON, please.
CDR: They're ON, Gordy.
CDR: And we're on a damping mode with Delta l, 2, 4, and ·.. 3 and 4.
CC: Roger, Gene;
CC: Okay, America. We've got another change to the changes. (Laughter) We'd like you to leave the IR on until our cue here.
CDR: Okay. I'11 change my change to my change. APOLLO 17 AIR-TO-GROUND VOICE TRANSCRIPTION
CC: America, Houston. The rates look good. We're ready to spin it up.
LMP: Hey, I was just wondering how the high gain's working out for you?
CC: Looking good, Jack.
LMP: Gordy, you said plus 157
CC: Affirmative. Plus 15 and a plus 185.
CDR: Gordy, the canister's changed.
CDR: I guess you're looking at the orange light, too, huh?
CC: Go ahead, Captain.
CMP: Okay, Gordo. I took my comm carrier apart - or, you know, cut this little cloth covering that goes from the plug on up to the headset, what have you. And sure enough, there's two little broken wires in there; and the next one is a little bit - the next one to it is a little bit loose, also. But I found a little piece of metal, and I bent it to the - conform to the shape of the wire and I've got it taped up real tight right now. And I'm going to see if it works for a while - make sure it doesn't cut in or out, you know, or something like that.
CC: Okay; good luck.
CMP: (Laughter) Okay. Of course, I still have the lightweight headset. I'd just as soon wear the comm carrier for the reentry, if possible.
CC: Roger. Say, we've investigated a little more on that possible spike that was alleged by Jack - thought he might have seen. And we mentioned, I think, in response to that, about a i or 2 amp Jump. Well, looking further, we see those all along; and we think they're probably due to minimum-impulse jet firings. We're trying to correlate that data. But the conclusion, right now, is that we really don't see anything on the data to support what Jack might have seen.
CDR: Okay, mighty fine. We - Just wanted to - you know, in case there was something there - wanted to make sure you all took a look at it.
CMP: Yes. Knobby. Okay, Knobby, where are you? Hey, I can see a few stars out there on this side of the window.
CMP: Can't see anything there. That's right behind the - By gosh, there it is, though.
LMP: Gordy, this is Jack. Is anybody watching my heart rate - heart rate over the last 15 minutes or so?
CC: That's affirmative. We have.
LMP: What - what did I peak out at?
CC: You peaked at 105, Jack.
CMP: Well, what do you know. You got to be quick. Just disappeared behind the ... limits.
CMP: No, not at all, Jack. Go ahead. Jack's going to stir the cryos again - not stir them but - de- stratify them. 36 Vega. Ahh, that Vega is nothing but a bear. (Laughter)
CC: Yes, we're all set.
CMP: Okay, about 58:45.
CC: Okay. And then, when you do that, we want you to stop the PTC right now. But we want you to use the jet configuration - configuration we used to start at - That's - all of quad Delta and Charlie 3 and 4, rather than the jets listed in the Flight Plan. Over.
CC: And while we are mentioning jet configurations, that jet configuration is - this is another change to a change to a change, and we're sorry about this. But we want you to use those jets, all of Delta and Charlie 3 and 4, for every stop and start of PTC from here on out, all the way through the final PTC exit, just prior to midcourse 7, which is shown in the Flight Plan - and - and the way we want it, using coupled jets for that final one. But use Delta i through 4, and Charlie 3 and 4 from here on out for going in and out of PTC. And I can read you all the time so that applies to - if you can Just remember it, that will save some writing. Your choice. Over.
CMP: I'11 write it down here in the spacecraft somewhere. and 4 for damping. And you want Bravo 2 and Delta 2 for spinup, as the Flight Plan says? entry and exit of PTC from here on out, except that final one, which is coupled just prior to midcourse. can go ahead and stop it right now. We'd prefer it that way, as a matter of fact. Over.
CDR: Yes, Gordy, our ball - our ball - let's see - reads about 256 ROLL, and YAW - and PITCH is 2 - about 227, and YAW is about 42 degrees.
CC: You know - evidently you definitely had a CDU glitch. We're trying to come up with an attitude that you can fly to on the ball as it stands right now in SCS. Standby.
CMP: Houston, both the SCS and the IMU ball are okay, I think. They're both the same. Well, they're almost - yes, except for the GDC - except for the GDC drift, they're both the same. So the error is in the NOUN 20s in the computer.
CC: Ron, does the - does the GDC and the IMU attitude agree right now?
CMP: And there's our NOUN 20s on the computer now.
CC: America, Houston. What we'd like you to do is - Were those ball angles you read 256, 04 - well, let's see - get the right order - 256, 227, and 042 - Are those still about where you are?
CMP: Yes, that's affirm.
CC: Okay. We're going to try to compute a - an attitude that can get us - to high gain so we have a little more visibility into the system. That's our problem right now.
CC: America, Houston. What we'd like you to do is roll 180 degrees to about 076 roll attitude.
CMP: Okay, we'11 roll her back to 076.
CC: Okay. Then once you get there, the HIGH GAIN angle should be a PITCH of minus 50; and YAW, 205. Over.
CMP: Minus 50 and 205. Okay.
CDR: We're on the way, Gordy.
CDR: You might check. I was loading NOUN 22. And you might just doublecheck and see what you saw down there and make sure I wasn't loading NOUN 20.
CC: Okay, good call; we'11 do that.
CC: Can you give us best OMNI as you roll around?
CMP: Okay, we'11 try
CDR: Okay, it's OMNI Delta now.
LMP: Houston, I doubt if it's a problem, but the UV cover's still open.
CC: Okay, we'd like you to zero the CDUs now.
LMP: Looks about right.
CDR: Looks good, Gordy. It matches the ball.
CDR: I don't know. You can track it down, but I called up NOUN 20 to check the roll angles, and it was not what we were using in the book here, of 14 de- grees. And I very easily could have - could have loaded 20 instead of 22.
CC: Okay. We'11 sure track that one down. f
CC: America, we're ready now for you to proceed on per Flight Plan with the VERB 49 to the sleep PTC attitude. We have not had a chance to go back over the data, but we'11 give you a call as soon as we get a chance to check it. Over.
CC: Yes, it sounds - it sounds like we might have the problem nailed down, but we'11 douhlecheek that.
CDR: This is a gross admission, if that's the case; but I'd rather have it that way.
CC: We won't hold it against you. 176/1 Tape APOLLO 17 AIR-TO-GROUND VOICE TRANSCRIPTION
CDR: Gordy, can I use the roll we got, 1427 I'11 stand by until you check that gimbal lock out.
CC: Stand by. We're checking that. Your answer is negative, Geno. The present roll - the maneuver should - shows on our computer, you'11 go to gimbal lock. So suggest you go to 14 and then start to maneuver .... Over.
LMP: Okay, Houston. The computer knows where the stars are anyhow.
CC: Okay. We'd like AUTO and NARROW, and make sure you've selected HIGH GAIN also.
CDR: Wise ... wise guy. Works every time, doesn't it?
CDR: Okay, I've been sitting here thinking about it. Yes, I had - and also the glitch occurred when I did the final ENTER, so - plus we had the two-axes glitch and a number of things. I'm - I'm glad you confirmed that. Makes me feel better.
LMP: We were discussing whether or not you needed an EMP or not.
CC: Well, there must be one for the situation.
CDR: Getting a little quiet up here anyway, Gordy. That one sure snapped us out, though.
CC: Us also.
CDR: Hey, how far are we from home?
CC: Well, I can give it to you in hours from entry interface right away - 38 hours _2 minutes and seconds. And in miles, you're 1_3 500.
CC: Picking up speed all the way.
CC: I've been talking to Don Beaty and Dick Kruse and looking over a transcript of - of a science press conference we edited up. It was kind of ragged but possibly interesting summary of the science as it stands now. In response to your question of - of items that might help you prepare for tomorrow's press conference, I can come with you with those words any time you wish.
CDR: ... you can come up with them now.
CC: Okay. Let's start with the - the LSPE. All eight charges have now been exploded, and they were all on schedule and produced excellent sig- nals. These data were used in conjunction with the ascent stage lift-off and also its impact data, which should give us an excellent picture of the geologic structure of the outer 3 kilo- meters of the Moon. This little summary I'm reading right now is - was written by Joel Watkins. The geophone array is functioning beautifully and and we're already talking about its potential in a listening mode for study of meteorite impact fre- quency. We still don't have precise EP locations from Ray Batson, so the following interpretation will almost certainly be changed when we get better data and field tapes, which we will use to refine our arrival times. Bearing the above in mind, my preliminary interpretation is as follows. The low-velocity layer seems to be thicker and higher in velocity than at either Apollo 14 or 16 sites. I think this may mean that the low-velocity layer here includes dark mantle material as well as the regolith. Details of the higher velocity substrata are fuzzy, but velocities increase with depth in a way which would be consistent with a thick ac- cumulation of lava flows. This probably repre- sents the suhfloor material. And he concludes by saying, "You guys did a great job, see you after splash." On the same subject, Dr. Kovach went a little further, and he just recently admits to seeing evidence of two high-velocity layers, especially after the 6-pound charge was fired, that - that evidence showed up. He also mentions in - mentioned in his press conference yesterday that the - the data point allowed by the - the ascent-stage impact was - was very important - the fact that they - they got it in about 9 kilo- and meters away the - that data is right in a critical range where - where they see a big change in the - the percentage of - velocity change. I'm getting kind of balled up here in the words, but that data is very important because it's in - where the steep gradient of velocity change occurs. On looking through here, t guess, in - in summary, I'11 read a couple of sentences again out of the press conference. We do find evidence of lunar crust as we did in the past, but we may have to thin it considerably. We may have, in fact, have to thin it as much as to 25 kilometers instead of 60 - that they believed it was up until now. And they're thinking they may have to lower the veloc- ity of seismic ways - waves in the mantle, which, I guess, at last guess was around 9 kilometers per second. Now it's looking more like 7.5, and the crustal velocity is probably as low as 6.3 kilo- meters per second. Okay, yes. That was - that last data was really from Dr. Latham, and he was interpreting that data mainly from the S-IVB impact and readings from some of the other seismic sites. Any questions on that? I realize that this is pretty ragged. Over.
LMP: Oh, that's - that's great, Gordy. Did Kovach in- dicate his tentative depth for the second high- velocity layer?
CC: No. As far as the information we have here, he's just - I - I don't see any - the only thing I can see is he mentions we're getting a depth sample down to 3 to 4 kilometers, but that was before all the charges had gone off. So I think, as I say, he just doesn't really state that yet.
LMP: Yes, it's a little early. Okay, good. Sounds like what we saw in the field to a certain extent.
CC: Okay. On the heat flow, it's continuing to work perfectly. It's stabilizing out and, at the present time, they show about a degree centigrade per meter gradient. Apollo 15 is stabilized at about 1.8, and it looks like the 17 site's headed for about the same, which gives consistent data for the two sites. It looks like that's what is going to result when it reaches final equilibrium. And so that - if you call that - those two sites typical of the Moon, then that leads one to the following conclusions; that that data requires that there be a total greater abundance of radio- active isotopes on the Moon as compared to the Earth, so there would be an implication here for a fundamental difference in the composition be- tween the two. And the higher number of isotopes would in turn require that they be located very near the surface, implying substantial differentia- tion of the material, at least compositionally or stratisfaetionally [sic]. It's not necessary that it had have to be stratified. It was only re- quired that it be stratified in most of - in that most of the isotopes be concentrated in the upper layers of the Moon. I guess that's about what we've got on the heat flow at the present time. Over.
LMP: Gordy, does he indicate where his minimum tem- perature lay - zone is now at the site?
CC: Stand by. Let me look through here.
LMP: I think you mentioned something the other night - about - I thought you said 2-1/2 meters, but I'm not sure.
CC: Let me just read it straight off here. There is some words to that effect, but it doesn't sound like 2-1/2 meters. At a large scale - let's see, he's describing a viewgraph here - the surface temperature at the time of this sample was 360 de- grees Kelvin. At a depth of about 15 centimeters, it had dropped to 280. At about 65 centimeters, the temperature drops to 254, and that's the lowest temperature we see. Below that depth, the temper- ature begins to increase again, and it's 257 at the bottom of the probes. Over.
LMP: Where was the 254 again?
CC: At 65 centimeters below the surface.
LMP: Okay. That's about the same, I think, as 15. Very good. Some of our double cores will get that deep.
CC: Roger. Okay, the TGE has produced some - fair amount of excitement around here - and interest. The instrument really worked beautifully. It had some baro switches that turned it on for temper- ature control - right aft - during lift-off - and so it had 3 days to stabilize before you got to Taurus-Littrow. And on landing, the bias measure- ment showed that the bias shift was extremely small, so they feel that they had a very accurate reading on all the readings. And I mentioned the other night that the number they got for the gravity field at the landing site should allow them to actually revise the value for the radius of the Moon at the landing site. But then you asked me about some of the variations in reading around the valley there. Well, it turns out that - if you call the landing site zero on the scale of milli- gals and then take the differences from the landing site, over to the South Massif, you have a minus 36; in other words, a lesser amount of gravity. And all these numbers, by the way, are corrected only for elevation, and there are some more sophisticated corrections to - to be put on them. But the - with - correcting for elevation, you have a 36-milligal negative anomaly at the South Massif. And the number at the North Massif was a minus 26. And there is very little dif- ference, within a milligal or so, between the North Massif and the Sculptured Hills site. But you can see that there's a significant difference between the landing site and the foothills on both sides. The Shorty Crater showed a slight positive anomaly compared to the landing site, but it's less than a milligal, which is sort of - you start to think "Well, that means a localized volcanic center," but it's - nobody's really going out that far on a limb. The - they were especially appreciative of the 2A stop, which was - let's see - well, it verified the extremely sharp gradient of the anomalous condition from the foothills as you go back into the valley. The 2A stop - I'm trying to find the number here - Okay, one's a minus 36 at station 2 to a minus 29 at 2A, so it's - it really changes quickly as you get away from the - the mountains. Okay, he summar - summarized his feelings by saying that - the negative gravity anomalies which were measured right at the South Massif and the North Massif clearly indicate that the valley is filled with a higher density of material than the material which makes up the massif so that if the material under- lying the floor at Taurus-Littrow - say, is basaltic in composition and has a density of about 3, the material which makes up the massif has a substan- tially lower density. He goes on to say that we're not sure exactly what the density difference is, but if it's as large as 20 percent difference, then the material in the floor of the valley and the - well, the thickness of the high-density material in the valley has to be on the order of about l-l/2 kilometers thick. So that's a - I guess that's a minimum thickness, assuming the greatest difference in densities. 176/7 Tape
CC: Yes. They're really - everything is really tied in the original theories on the structure and makeup of the valley. Everything seems to be fall- ing right in there, and that's what has - has the whole crowd of scientists around here really smiling. Let's see - let me find out what's next here. Okay. It was Strangway's turn next, and he didn't have any results to present, of course, because he's got to get the tape back first, really. sounder However, the orbital - the command module sounder - when they made the pass across the site with the transmitter on - No, I got it backwards. When it was in a listening mode, listening to the ground transmitter's signals, they found that the signal was in exactly the frequency range that it was supposed to be, and they - they picked up the - exactly the right sequence rate, once every 0.8 sec- ond. And when they calculated the power levels, that we were putting out just exactly the 1 watt that we were expected to put out. So that - that everything looks good as far as the operation of the transmitter, and without going into all the details which you know as well as I do about the thermal problems on the receiver, they're still - well, he sums it up, we have no reason yet to be sweating it too badly. They're very hopeful that when the tape gets back, we'11 have good data on at least some of the legs, and they're - they're waiting for you to bring it to them. Dick Kruse is here, and he mentioned that all your pains, Geno, in brushing dust off of it probably saved the day. If it's there, it was just due to that, that it did work, because it was really on the ragged edge here.
CC: About what's left, I think - is the field geology interpretation. And what I've got and can get tonight because there's no one really around here from the geology team at this time - it's about 11 o'clock at night - is so rambling that I'm not going to bother to read it to you. But I will leave a request so that when Parker get you up in the morning, maybe he can summarize that or answer any questions in that area that you might have. Over.
LMP: Okay, Gordy. Thank you very much.
CC: No trolfole at all.
CMP: Hey, Gordy. Everything under control at the home front?
CC: Yes, Ron. As a matter of fact, talked to Jan and, well, her words to s_mmarize the - the whole show that you put on this afternoon was "out of this world," which is, I guess, a pretty good way to put it. Jon and Jaime were speechless when you waved and called hello to them. And Jan closed by saying that you - you're going to have to hurry home and help rebuild the wall that was broken out by a huge mob of people that were in your house this afternoon during the EVA. Over.
CMP: Well, that's okay. We like a lot of friends, and I'm glad everybody enjoyed it and pass my love on - to everyone.
CDR: What g_out the other side of the tracks, Gordy? Got any words from over there?
CC: Hey - I haven't really talked to anyone in the other two families today. So I'm sure that every- thing is fine or we would have heard it, but I'11 try to get a last-minute update on that before you hit the sack.
LMP: Gordy, this is Jack.
CC: No, Jack. I don't have that. I'11 ask, but I think the ones I gave you, the four places, Shorty, North, South, and Sculptured Hills, are all we got. But I'11 check.
CDR: Gordy, I'm sorry. I'm going to move.
CDR: Gordy, this isn't my day. I'11 give you the damp- ing again.
CC: 17, Houston. We're ready for spinup.
CDR: Gordy couldn't hack it any longer, huh?
CC: He's getting some more news for you.
CDR: Okay, we'11 try and get it right this time.
CMP: Houston, America. Are you ready for REACQ and NARROW on the HIGH GAIN?
CMP: Okay, you have it. REACQ and NARROW.
LMP: Gordy, that's verified.
CC: Okay, thank you. I - I have a number of sort of cleanup items before going to bed that I can give you any time.
LMP: Why don't you go ahead?
CC: Okay. We'11 be calling you for the IR, OFF, before you go to sleep. Want to leave it ON right up to the last minute, I guess. Let me see if we can do this next one. Okay. Why don't you just go ahead and do this one? H 2 FANs for sleep - num- ber l, OFF, and 3 in AUTO.
CC: And there'11 be no cryo stir necessary. You can leave the OPTICs power switch ON, which will in- crease the heat input and keep it a little bit warmer in there. You won't have to turn that off per the presleep checklist, if you don't wish to. We are going to change the biomed - -
CMP: take the next shift where in the Flight Plan it now calls for the CDR. It was really our mistake on the original change. I guess there's no need to call all those detailed Flight Plan changes now unless you want to copy them. A reminder also, prior to going to sleep, to bump the cabin up to 5.7 with the OPS to start getting the gas out of the OPS. And I checked with the remaining two homefronts, Jack. Your - I talked to your mother and sister. Every- body's fine there, and they watched the top of your head a little bit this afternoon on the EVA. They're looking forward to seeing you tomorrow on the press conference and back on Earth shortly thereafter. I got one from Nassau Bay, too, if the co_nander's listening.
CC: Okay, 17. Loud and clear now. How me?
CC: Okay. Did you - did you get the homefront update for the commander?
CDR: Yes, I got it, Gordy, and that's great news and news I wanted to hear, and you can return my love to them for me if you would.
CC: Sure will. That completes our list of goodies with the exception of the normal presleep stuff, and we'11 be standing by for that from you.
LMP: Okay. And you can tell the Arizona people, next time you talk to them, I tried to get more of myself out in that television picture but the
CMP: saw to it that my umbilical was limited in its length.
CC: You guys call while we were unplugging?
CC: Okay; we copy. CABIN FAN is already OFF.
LMP: That's right. It turns out the request was to turn it on, so we will.
CC: Okay, understand you're going to turn the CABIN fan, ON. I think that's to keep it a little bit warmer in there for you guys.
CDR: Give him about - 5 or 10 minutes and he'11 be with yOU.
CC: Okay; have him give us a call when he gets ready.
CC: Okay, we panicked there, I guess, or we got our - change, we - because we saw you go VOICE, OFF, and we wanted to talk to you guys about two or three things before you went to bed. For one thing, we don't see the cabin pumped up yet with the OPS as per Plan and we don't have the onboard read-outs yet, and we'd like to find out who's going to be on the comm and talk to Ron about his headset. I guess the general concensus of opinion down here, unless we know more about the fix, is there are some possible serious consequences, like blowing up the audio panel, if those wires did get together and short out, depending on which wires they are. So there's some concern about that.
CDR: Okay, let's get you the read-out first, and we're going to bounce up the cabin here very shortly with the OPS.
CC: Okay, we'd also like to get the INFRARED to OFF, please - the IR.
CDR: Okay, it's coming off here shortly. Okay, Bob, the RC - RCS reads 65, 57, 61, and 60.
CC: Okay, copy those.
CDR: Houston, are you reading America?
CC: I'm reading you now. The last thing we got from you was the RCS quantities. We didn't get the bat quantities.
CDR: You haven't heard Eon at all?
CC: No, haven't heard Ron a bit.
CC: Sounds like the headset - -
CDR: Well, I'11 tell him to try again.
CC: No, America, we're not reading Ron at all, right now.
CDR: Okay, he's been on the lightweight headset talking to you all this time. Wait a minute, he's going to check a couple switches.
CC: Okay. Which headset is broken? The Snoopy?
CDR: Yes, Ron's - Ron's Snoopy helmet.
CMP: Hey, are you reading me now, Houston?
CC: I read you loud and clear now, Ron.
CMP: Okay, I'm wearing the lightweight headset, now. On the comm carrier, there's a whole bunch of wires, about eight of them- looks like they're twisted pairs, you, know, twisted in fours really. They come up through the thing. And two of those eight wires are cut - are broken in two. The hot end, or the end that comes up from the plug going toward the headset - those two wires both come out individually and individually taped, each one of them. And then the whole group - you know, I bent them out of the way so they wouldn't be touch- ing anything. So they wouldn't touch insulation or tape. I bent them out of the way and taped the whole side of it just to keep the rest of them from breaking in two, and it looks like a pretty good fix on the thing, really. However, if you have any concern about blowing the audio panel - I'11 just go ahead and wear the lightweight headset.
CC: Okay, Ron. Yes, the concern here is not only which wires they are - the potential does exist if one of those shorts to ground to blow the audio panel or at least a circuit breaker, depending upon which wire it is. I gather that what you've done - is that you haven't wired the broken wires back together, but it's just sort of covered the bare leads and wired them out of the way. Is that right?
CMP: Yes, that's correct. It was too close to the - there is a stiff piece of plastic that comes out of the headset itself, out of the bottom of the left earset, and it's broken off too close to the bottom of it there to - to strip the wires down and wire them together at all.
CC: Okay. Roger on that. I guess - let us think about it here overnight. Offhand, our opinion is, as long as you've got a spare headset, let's wear the spare headset - that spare meaning a light- weight. If you're going to be on comm tonight, I guess we offhand suggest wearing the lightweight tonight. Over. How does that strike you?
CMP: Okay. Yes, no problem. I won't be on eomm tonight, but I'11 be wearing the lightweight headset anyhow. The only time I was thinking about it - wearing the other one at all - would be for entry, and there's no problem there. I'11 just stick to the lightweight headset around my neck and put that one around my ears just to use as a bump pad, is all.
CC: Okay; let us think about it overnight, and we'11 talk to some people about it. Let's see, is Jack going to be on the headset tonight and the biomed, both?
CDR: Yes, Jack will be on tonight with the biomed and the headset.
CC: Okay. We'd like to get one more valve check there, America. Like to check our WASTE WATER TANK INLET valve to AUTO. EECOM says he is in a flat portion and he can't verify that right now by buildup.
CDR: WASTE TANK INLET is in AUTO, Bob.
C: and pyro BATs A and B.
CC: Okay, we copy that. And let me ask you a question here, Gene. Right now you're an hour behind get- ting to sleep. Do you want to sleep the 8 hours or get up by the Flight Plan?
CDR: No, let's get up per the Flight Plan. We're very much aware of - of that; we've just been doing some restowage and a few other things around here. But let's get up per the Flight Plan and fine.
CC: Okay. We'11 talk to you in the morning. As soon as the cabin is pumped up, you're GO for sleep and you can turn VOICE back OFF, at your convenience.
CDR: Okay, you'11 see the cabin pumped up, we'11 go to 5.7 and turn the OPS back OFF.
CDR: Okay, babe. Take care.
CDR: Bob, are you going to want to do that again t omo rrow?
CC: Yes, Gene. I will do it again prior to finish emptying the OPS.

LMP: Good heavens. It sounded like Bob Parker.
CC: Roger. And in case you didn't recognize it, that was "It's Only Just the Beginning."
LMP: Or words to that effect.
CC: And, Jack, if you give us a call when all three of you get in the headsets, we've got something else to play for you this morning.
LMP: You have a call.
CDR: ... Houston, good morning.
LMP: I just gave you a call.
CC: Okay. We'11 cue up something else for you guys. And, Ron, this was something that was recorded over at your house yesterday morning. I think you'11 recognize it.
CMP: (Laughter) I'11 have to wait and see. (Music: Christmas carol recorded by Ron Evans' neighbors) Jon Hi, Dad. Evans
CC: Okay. One minute to COVER CLOSE - UV, that is.
CMP: Hey, Houston; America. Sounds like people are getting in the Christmas spirit around the Houston area there.
CC: That's affirm. It's a little bit warmer this morn- ing, but it still feels and looks a lot like Christ- mas down here.
CDR: Well, Bob, it feels and looks a lot llke Christmas up here, too.
LMP: Matter of fact, the LEB reported a temperature of about a minus 2 last night (laughter).
CC: Okay; and 15 seconds to UV COVER CLOSE. Five seconds.
CC: MARK, UV COVER, CLOSE.
LMP: Yes, the LEB was cloudy, cold, and snowy last night.
CC: Snowing too, hey? We're showing you 61 degrees in the cabin this morning, with a suit temperature of 48 degrees.
LMP: Glad I'm not in those suits.
CC: You could have crawled inside the L-shaped bag, I guess.
CC: Okay. And America, we'd also like to get BAT A to CHARGE.
CC: You're welcome for the answer. Well, we're trying to keep your spirits up today.
CC: This is the new CAPCOM one. Say again the ques- tion. Four degrees equals distance from the Earth?
LMP: Yes, sir. What does 4 degrees equai in miles from the Earth?
CC: Retro says that 4 degrees essential angle equals 94K. You guys are out at about 125K right now.
LMP: Okay, Bob, I was looking at the Flight Plan, and it said field of view is 4 degrees.
CC: And we're going to have a network handover. We may be a momentarily - momentary dropout.
CC: 17, did you call?
CC: Okay. We've all set.
CDR: menu - I'11 try negative reporting. He did not eat three apricot cereal cubes, pears. And at lunch he did not eat the half a cereal bar. And at dinner he did not eat tomato soup, half a hamburger, and the date fruitcake. On lunch he had also - positive now - lemonade, two pecans, and one-fourth of a chocolate bar. Okay. And - last night, he had about 5 hours of fair sleep, no medication, and 2-1/2 cans of water. And his PRD is 17060? That's right, 60. Okay. For the LMP, day 12: He did not eat for breakfast, pears. For lunch, looks like he ate it all. For dinner, he did not eat the tomato soup, half a hamburger, mustard, pudding, and that's it. And add to breakfast another cup of coffee - bag of coffee; excuse me. And the lunch, an orange drink, an orange-pineapple, another coffee, graham cracker and cubes - four of them, two pecans, one-fourth of a chocolate bar. And - his PRD is 24188, and 6 hours intermittent sleep, 1-1/2 cans of water, and took one Lomotil last night, just as we were turning in, as a result of the Evans affair catch- ing up with the LMP. The
CMP: - negative reporting again- did not eat sausage, fruit cocktail, orange beverage. And for lunch, he did not eat the peaches. And for dinner, he did not eat tomato soup and the caramel candy. Add to break- fast, coffee, four sugar cookies and four Jelly candies. That's for breakfast. To lunch, add lemonade, coffee, two pecans, and _one-fourth of a chocolate bar - one-half of a chocolate bar; excuse me. Okay. His PRD is 15058. He had about 5 hours of fair sleep and two sniffs of nose drops and two Lomotils yesterday. And he had five cans of water. And that should do it, Bob.
LMP: Thank you for your indulgence.
CC: Thank you for your report. We appreciate it.
CC: Roger, Jack. Go ahead.
