Public Affairs Office - "This is Apollo Control, Houston at 147 hours, 12 minutes now into the mission. We're less than a minute away now from reacquiring Apollo 12, and when we pick up the spacecraft we expect that Pete Conrad and Al Bean will be in the final phases of making good their transfer back to Yankee Clipper. We'll stand by and monitor at this time. This is Apollo Control, Houston. We're now receiving data. This is Apollo Control, Houston at 147 hours and 15 minutes. We've not yet attempted to contact the Apollo 12 crew assuming that they are quite busy now in the final phases of their transfer."

[Flight Plan 3-127.]
[AOS Rev 33 147:12.]
147:16:08 Carr: Intrepid, Houston. How do you read?

147:16:14 Bean: Read you loud and clear.

147:16:15 Carr: Roger. Yankee Clipper, how do you read?

147:16:19 Gordon: Houston, loud and clear.

147:16:21 Carr: Roger; read you both the same. [Pause.]

147:16:54 Carr: Yankee Clipper, Houston. Pete, are you in the Clipper now?

147:17:01 Gordon: Pete's - Pete's reading the checklist to Al. Hey, Jerry, I got a question.

147:17:08 Carr: Go.

147:17:09 Gordon: Pete wants to know if he can leave his LCG in the LM.

147:17:17 Carr: Okay, Dick. Stand by. We'll get an answer on that. I got a couple of questions for them – would you relay them?

147:17:27 Gordon: Yes, I can, Jerry. They're going through their checklists, so they can get out of it.

147:17:32 Carr: Okay. Here's our - here's our questions...

147:17:35 Gordon: [Garble] ask the questions.

147:17:36 Carr: ...You know that hanging metal they were talking about on the Service Module? We're wondering if that's in a position such that it might possibly be the cause of our S-band antenna problem, causing it to dither.

147:17:59 Conrad: It's further up than that - it's right around the SEP plane of the service module, and it's right on the top of Dick Gordon, whereas his S-band antenna's on his bottom left, if you go relative to the upper windows.

147:18:18 Carr: Okay. We copy that, and the other one is, don't forget to bring the LM TV camera across.

147:18:26 Conrad: We've already got it, and it's stowed on the Command Module, and we put it in one of those special bags because it had a lot of dust on it.

147:18:34 Carr: Roger. Good.

147:18:40 Conrad: Hey, and also, Houston, we need to know if we can just go ahead and leave our LCG's here, or do you want them brought back?

147:18:47 Carr: We're checking on that now, Pete.

[Comm break.]
Public Affairs Office - "The LCG referenced there is the Liquid Cooled Garment. We are at 147 hours, 20 minutes now in the flight."

147:21:11 Carr: Clipper, Houston.

147:21:16 Gordon: Go ahead, Houston.

147:21:17 Carr: Roger. High Gain antenna's not doing too well. We'd like you to go Manual, and your angles are pitch, minus 4l; yaw, 4. Over.

147:21:52 Carr: Intrepid. Houston.

147:21:58 Conrad: Go ahead, Houston.

147:21:59 Carr: Roger. On your LCG question, the only problem we have right now is in the area of contamination. We're giving it a quick checkout on that and we'll have an answer for you in just a few minutes.

147:22:22 Conrad: Say again, Houston.

147:22:26 Carr: Intrepid, Houston. The only problem that – the question mark we have with the LCG being left in the LM is the contamination thing. We're getting an okay on it, and we will get back with you in just a couple minutes.

147:22:39 Conrad: Understand. [Long pause.]

147:22:57 Carr: P30 looked good, Al.

147:23:16 Carr: Clipper, Houston. I have a CSM DAP load for you and a map update for Rev 34. [Pause.]

147:23:33 Gordon: Go ahead, Jerry.

147:23:35 Carr: Okay, Dick. Your CSM weight is 35,634. I've got your trim angles anytime you need them. Your map update is Rev 34; LOS is 148:24:47, 148:2 - correction, 49:43, 149:11:01.

147:24:10 Gordon: Roger. I copy that, and the CSM weight is 35,634.

147:24:15 Carr: Affirmative, Dick.

[Comm break.]
147:26:44 Carr: Intrepid, Houston.

147:26:50 Conrad: Go ahead, Houston.

147:26:52 Carr: Roger. You can leave those LCG's in the LM if you want to, and let us know where you stowed them, would you?

147:27:00 Conrad: Will do.

147:27:07 Conrad: We're going to leave them in the CSM ditty bag which will be on the floor.

147:27:13 Carr: Okay, fine.

[Comm break.]
Public Affairs Office - "This is Apollo Control Houston. We're still looking for LM jettison time of 147:54:30, a bit more than 20 minutes from this time. We're now at 147 hours, 29 minutes into the flight."

147:31:43 Carr: Intrepid, Houston.

147:31:52 Gordon: Hello.

147:31:53 Carr: Roger. Have you got your master alarm circuit breaker closed?

147:32:02 Gordon: It's open.

147:32:09 Carr: Okay, Dick.

147:32:10 Gordon: What would you like, Houston?

147:32:12 Carr: No, that's fine the way it is.

147:32:14 Gordon: Is it okay? Okay.

[Long comm break.]
Public Affairs Office - "Flight director Glynn Lunney just quickly advised his flight control team we've completed all of the work in the Lunar Module as far as we know and we're standing by at this time for the crew to secure the hatch. We're at 147 hours and 35 minutes into the flight of Apollo 12."

Public Affairs Office - "This is Apollo Control Houston while we're standing by, why don't we quickly go over some of our upcoming Ground Elapsed Times for events. Looking at Ground Elapsed Time for the jettison of the Lunar Module of 147 hours, 59 minutes 30 seconds. A Ground Elapsed Time for Command and Service Module separation maneuver of 148 hours, 4 minutes 30 seconds and a G.E.T. for ignition of the..."

147:36:41 Gordon: Hello, Houston; Clipper.

147:36:44 Carr: Roger, Clipper. Go.

147:36:48 Gordon: Do you want to send something to the LM to see if the uplink is okay? How about a Verb 47?

147:36:58 Carr: Stand by just a second, Dick. [Long pause.]

Public Affairs Office - "We're looking at a G.E.T. for the ignition - the deorbit burn of 149 hours, 28 minutes and 14 seconds. With a G.E.T. for impact of 149 hours, 59 minutes and 51 seconds."

147:37:26 Carr: Clipper, Houston. We're going to send an Error Reset.

147:37:49 Carr: Yankee Clipper; this is Houston. Intrepid is Go; you can clear it out any time.

147:37:56 Conrad: Roger. We've been trying to.

147:42:10 Gordon: Houston, Clipper. How about a Pyro Arm? Here comes, the Logic, On, for you.

147:42:16 Carr: Roger, Clipper.

147:42:29 Carr: Yankee Clipper, Houston. Go for Pyro Arm.

147:42:34 Gordon: Roger. Go for Pyro Arm.

[Very long comm break.]
Public Affairs Office - "This is Apollo Control, Houston, at 147 hours and 43 minutes. We presently show Apollo 12 with an apolune of 62.6 nautical miles, perilune of 57 nautical miles."

Public Affairs Office - "This is Apollo Control, Houston, at 147 hours, 50 minutes now into the flight of Apollo 12. We've not yet received verbal confirmation from Commander Pete Conrad and Al Bean that they are both now back in Yankee Clipper, but we feel reasonably assured that they have effected their return. We are standing by at 147 hours, 51 minutes into the flight."

Public Affairs Office - "This is Apollo Control, Houston, at 147 hours, 53 minutes into the flight. Our two clocks in Mission Control, the bottom clock identified as ET is counting down to jettison. We're at 5 minutes, 45 seconds away. The top clock counting down to Command and Service Module separation, the separation by Yankee Clipper. We are now 10 minutes and 30 seconds away from that event."

147:57:31 Gordon: Houston, Clipper. Two minutes to Jettison.

147:57:34 Carr: Roger, Clipper.

[Comm break.]
[Flight Plan 3-128.]
Public Affairs Office - "That was Dick Gordon reporting from the Yankee Clipper that they're now less than 2 minutes from jettison of Intrepid. All 3 crew members now back in the Yankee Clipper."

Public Affairs Office - "About 20 seconds away from Jettison now."

Public Affairs Office - "Guidance and Control Officer reports that the two spacecraft's have separated. We've received no acknowledgment yet from the crew but on ground base displays we did readout the Jettison of the Lunar Module."

148:01:00 Carr: Yankee Clipper, Houston. Go to Reacq on the High Gain. Over.

148:01:07 Conrad: Roger.

[Long comm break.]
Public Affairs Office - "We have a report that the Command Service Module has now completed the separation maneuver at 5.5 second burn of the reaction control system engines."

148:06:42 Carr: Yankee Clipper, Houston.

148:06:48 Conrad: Houston, Clipper. Go.

148:06:49 Carr: Roger. Your High Gain's beginning to jitter again. Better go Manual, and your angles in the Flight Plan are good. That's minus 36 on the pitch and 352 on the yaw.

[Long comm break.]
Public Affairs Office - "This is Apollo Control at 148 hours,10 minutes. LMs systems engineers report all systems on Intrepid looks good after the jettison and subsequent CSM separation. The times we have for those two maneuvers are as follows: 147 hours, 59 minutes, 30 seconds for the Jettison of the Lunar Module, and 148 hours, 4 minutes, 30 seconds for the separation maneuver performed by the CSM. We show 13 minutes, 50 seconds now until Loss of Signal from Yankee Clipper. Our Flight Director on this shift is Glynn Lunney and the Capsule Communicator coming on is Astronaut Don Lind. There will be a Change of Shift Briefing shortly in the News Center, Houston News Center. The participants are leaving at this time."

148:12:23 Lind: Apollo 12, Houston.

148:12:28 Conrad: Hello.

148:12:30 Lind: Pete, the surgeon has some words for you about your sensors - sensor irritation, if you want to listen to that.

148:13:00 Gordon: Why don't you stand by until they get some coffee?

148:13:03 Lind: Roger.

[Long comm break.]
Public Affairs Office - "This is Apollo Control at 148 hours, 15 minutes. Our Flight Dynamics Officer has just reported that the LM Jettison produced negligible effect on the Lunar Module trajectory, and should have no effect on the Time Of Ignition or the Delta-V required for the LM deorbit scheduled to occur on the next revolution. That maneuver is now planned to occur at 149 hours, 28 minutes, 14 seconds with a Delta-V retrograde 191.3 per second. That will be a Reaction Control System maneuver. Total duration of 1 minute, 21.4 seconds."

148:19:03 Lind: Apollo 12, Houston. [Long pause.]

148:19:16 Lind: Apollo 12, Houston. Omni Bravo, please. [Long pause.]

148:19:47 Lind: Apollo 12, Houston in the blind. Omni Bravo, please. [Long pause.]

Public Affairs Office - "We're continuing to have signal strength variation through the spacecraft High Gain antenna. CapCom, Don Lind requesting that the crew switch to one of their Omni antennas. Our ground station, at the present time is Madrid, where we have an 85 foot Dish, and we should be able to get fairly good communications through the Omni antenna without ground receiving antenna."

148:20:29 Lind: Apollo 12, Houston. [Pause.]

148:20:36 Conrad: Hello, Houston; 12. Go ahead.

148:20:37 Lind: Roger. We recommend that you shut off the High Gain. First, put the Track switch on Manual; next, put the High Gain Power switch to Off, and talk to us through Omni - we assume you're on Omni Bravo. We think that should be a good one.

148:20:57 Conrad: Your assumption is correct. [Long pause.]

Public Affairs Office - "Flight Director, Glynn Lunney now taking a status from all of his flight controllers. Now 3 minutes before Loss Of Signal on the Command and Service Module. The report all around the room is that we look good."

148:21:43 Lind: Apollo 12, Houston. Everything looks in good shape down here. Also, the LM looks in good status for the deorbit burn.

148:23:58 Lind: Apollo 12, Houston. We show about 45 seconds to LOS. You'll be coming around the corner at 149:11.

148:24:10 Conrad: Roger, Don. Thank you.

[LOS Rev 33.]
Public Affairs Office - "This is Apollo Control. We've had Loss Of Signal now. We'll reacquire the spacecraft on its 34 revolution at 149 hours, 11 minutes or about 46 minutes from now. At this time, we'll switch to the Houston News Center for the Change of Shift Press Conference which is scheduled to begin at this time."

Public Affairs Office - "This is Apollo Control at 149 hours, 10 minutes. We are now about 1 minute from reacquiring the spacecraft on its 34th revolution of the Moon. During this Rev the major activity will be the LM deorbit maneuver. That's to be performed at 149 hours, 28 minutes, 14 seconds causing the LM to - LM ascent stage - to impact the lunar surface at 149 hours, 55 minutes, 53.2 seconds. The maneuver, which deorbits the LM will be performed with the Lunar Module reaction control system thrusters. The burn time – burn duration will be 1 minute, 21.4 seconds producing a retrograde Delta-V of 191.3 feet per second. The maneuver will be performed at 14.22 degrees South latitude and 62.5 East longitude, which will be just about over the Sea of Fertility. The impact point is predicted to be about 4.8 miles South of the Lunar Module decent stage. The impact co ordinances are 3.31 degrees South and 23.43 degrees west. The predicted velocity of impact is 5508 feet per second and we predict that We will have."

[AOS Rev 34 149:11.]
[Flight Plan 3-129.]
149:12:23 Lind: Apollo 12, Houston.

[Comm break.]
Public Affairs Office - "We have Acquisition Of Signal now and CapCom Don Lind has put in a call to the crew."

Public Affairs Office - "Picking up we expect the propellant remaining in the lunar module descent stage to be about 350 pounds at impact and the propellant remaining in terms of Delta-V will be about 394 feet per second. Our communications engineer has just reported that we are having a bit of a problem locking up on the Command Module at this time and we will continue to stand by."

149:13:28 Lind: Apollo 12, Houston. Apollo 12, Houston.

[Comm break.]
Public Affairs Office - "And we have a good solid lockup now. The control systems engineer reports that the LM looks good at this time. We now show 12 minutes, 53 seconds, till ignition for this Lunar Module ascent stage deorbit. One of the primary purposes for the maneuver is to give us a calibrated signal on a given level of energy is transmitted through the lunar surface to the passive seismic experiment. We had indications from the previous seismic experiment left on the Moon as to what sort of signals we get from the instrument. We don't, however, have a good handle on how a given level of energy is transmitted the lunar surface. It is hoped by impacting the LM ascent stage, which has a known mass and a known velocity, it will help us in interpreting previous and subsequent seismic signals from the passive seismometer."

149:15:31 Lind: Apollo 12, Houston.

[Comm break.]
Public Affairs Office - "Network controller reports that we still do not have good two-way lock with the Command Module and we will be trying to transmit in the blind to Dick Gordon.

149:18:04 Lind: Apollo 12, Houston. [Long pause.]

149:18:23 Lind: Apollo 12, Houston in the blind. For your information, for P20 tracking of the LM with the sextant, you'll get a program alarm 20430 when the LM vector intersects the surface. With a Verb 66 Enter and reset the alarm, you'll clear that. Impact time at the surface should be 149 plus 55 plus 59. That's when you should get the alarm 20430, and it's only the LM vector passing through the surface.

[Comm break.]
Public Affairs Office - "CapCom Don Lind just passed up a new impact time for the LM ascent stage, updated about 5.8 seconds from the previous time we had. The current prediction for impact is 149 hours, 55 minutes, 59 seconds. The altitude of the Lunar Module ascent stage at the beginning of the deorbit burn Will be about 57.8 nautical miles. The predicted flight path angle at impact will be about 3.68 degrees. We also have a predicted crater size for the LM impact. The prediction for that crater is it will be elongate about 6 meters wide and about 12 meters long with a depth of about 4/10's of a meter to 6/10's of a meter and at this time we still do not have good two-way lock with the Command Module. We are getting good data from the LM."

149:21:41 Gordon: Hello, Houston; Yankee Clipper.

149:21:44 Lind: Loud and clear. How are you doing, Dick?

149:21:52 Lind: Apollo 12, Houston.

149:21:55 Gordon: Doing pretty good. I've got the LM in the sextant. And I've been tracking him, and I've got the camera [garble] right now watching the LM. What time is that burn scheduled for?

149:22:07 Lind: Okay. The burn ignition time is 149 plus 28 plus 14. Did you get a transmission from us in the blind about 2 minutes ago about a program alarm?

149:22:22 Gordon: Negative.

149:22:24 Lind: Roger. If you're going to track in P20, which we see you're setting up for, when the LM vector intersects the lunar surface, you will get a program alarm 20430. When you go Verb 66 and Enter and put your vector in that slot deal and Reset, the alarm should go away. Now, the impact time is expected to be 149 plus 55 plus 59.

149:23:05 Gordon: Okay, fine. Thank you.

149:23:07 Lind: Roger. We've got some other goodies for you. We've got a P40 maneuvering PAD, when you're ready to copy; we've got some words for Pete about his skin irritation; we've got consumables PADs and a few other things when you want them.

149:23:26 Gordon: [Garble], Don. I'm trying to track this LM while these guys are still packing the spacecraft.

149:24:18 Lind: Apollo 12, we're not reading you very well on that last transmission. Could you give that again?

149:24:26 Gordon: Give what again, Don?

149:24:28 Lind: Your last transmission. You were breaking up.

149:24:34 Gordon: I said you'd better hold all that stuff awhile. Pete and Al are trying to pack this spacecraft, yet, with all the stuff they brought back from the LM; and I'm trying to track the LM itself. So we won't have time for anything else right now.

149:24:48 Lind: Very good. We'll hold it.

[Comm break.]
Public Affairs Office - "We're coming up now on 2 minutes, 20 seconds until ignition of the LM ascent stage. That ignition signal will be transmitted via radio signal from Mission Control. The scheduled landing impact time is now 29 minutes, 44 seconds away."

Public Affairs Office - "Coming up now on 1 minute to ignition. Our LM guidance engineer says we are clearing out to command the LM. Guidance. [Apollo Control] Houston, 1 minute to LM ignition."

149:27:13 Lind: Apollo 12, Houston. One minute to LM ignition.

149:27:22 Gordon: Roger.

[Comm break.]
Public Affairs Office - Coming up now on 20 seconds to ignition. 10 seconds, 9, 8, 7, 6, 5, 4, 3, 2, 1, and we have retrofire. Guidance confirms we are burning all four jets."

149:28:28 Lind: Apollo 12, Houston. The LM is on its way down.

149:28:35 Gordon: Roger [garble]. [Long pause.]

Public Affairs Office - "Thirty seconds into the burn. Guidance reports accelerations look good, up to 36 feet per second, total Delta-V to be gained 191.2 feet per second."

149:29:07 Gordon: Houston, 12.

149:29:09 Lind: Go, 12.

149:29:13 Gordon: Is the LM still burning?

149:29:16 Lind: That's affirmative.

149:29:20 Gordon: Okay.

[Long comm break.]
Public Affairs Office - "Thirty seconds into the burn. Guidance reports accelerations look good, up to 36 feet per second, total Delta-V to be gained 191.2 feet per second."

Public Affairs Office - "Our Flight Dynamics engineer estimates, based on preliminary tracking, that we're going to be about 20 miles short the predicted or planned impact point had been about 5 miles, 4.8 miles South of the Lunar Module descent stage. The prediction now is that it will be about 20 miles short. We're standing by for the Flight Dynamics Officer to come up with a predicted set of coordinates for impact."

149:32:26 Gordon: Houston; this is 12. Let me know when he finishes burning. [Long pause.]

149:32:48 Gordon: Houston, Apollo 12.

149:32:50 Lind: Houston, go ahead.

149:32:59 Gordon: Roger. Will you let me know when he's through with the burn, please?

149:33:05 Lind: Say again, 12.

149:33:12 Gordon: Will you call and let me know when the LM finishes its burn?

149:33:17 Lind: Okay, it has finished its burn now. It's been over about a minute and a half.

149:33:24 Gordon: Thank you.

149:35:58 Lind: Apollo 12, Houston. We show just under 20 minutes until; LM impact.

[Long comm break.]
Public Affairs Office - "We're now 19 minutes from predicted impact. The predicted weight of the LM ascent stage at impact is 5,254 pounds."

149:39:56 Lind: Apollo 12, Houston. We've computed a new impact time for the LM impacting the surface at l49 plus 55 plus 17.

149:40:11 Gordon: Roger.

[Long comm break.]
Public Affairs Office - "We're now a little less than 15 minutes from the scheduled time of LM impact. The new impact time passed up to the crew by CapCom Don Lind was 149 hours, 55 minutes, 17 seconds. We also have some new impact coordinates. The latest estimate from the Flight Dynamics Officer is the impact will occur at 3 point 95 degrees South latitude. Twenty-one point seventeen, 21 point 17 degrees West longitude and we should have that broken out in actual miles from the LM descent stage shortly."

Public Affairs Office - "We're now coming up on 10 minutes until the LM impact. The Flight Dynamic Officer advises that the impact point should be about 39 miles East-Southeast of the targeted point. The targeted point was about 4.8 miles south of the LM landing site."

149:49:04 Gordon: Hello, Houston; Apollo 12.

149:49:07 Lind: Go ahead, 12.

149:49:10 Gordon: Roger, Don. Let's get caught up on some of those PADs. Let me know when that thing impacts, so I can shut off this camera, because I can't see it through the telescope?

149:49:18 Lind: Roger. We've got 6 minutes to impact, and I've got a P40 TEI PAD for you.

149:49:54 Gordon: Okay. Go with the TEI PAD.

149:49:57 Lind: Roger. TEI-39, SPS/G&N: Noun 47 is 35629; Noun 48 is minus 0.67, plus 0.44; GET 160:42:19.26; Noun 81, plus 3463.6, plus 0671.1, minus 0128.2; roll, NA; pitch, 109; yaw, NA; all the rest is NA; ullage, four jets, 11 seconds; and this assumes no plane change 2.

149:51:09 Gordon: Okay. Copy TEI PAD 39. SPS/G&N is 35629; minus 0.67, plus 0.44; 160:42:19.26; plus 3463.6, plus 0671.1, minus 0128.2; pitch is 109; four jet, 11 seconds; no plane change 2.

149:51:33 Lind: That's affirmative.

149:51:40 Lind: Does Pete want to hear some recommendations from the Flight Surgeon on his skin irritation?

149:51:53 Gordon: No, he doesn't need any information on that.

149:51:56 Lind: Okay. I've got a consumable PAD for you, if you want it.

149:52:08 Gordon: You've got some what? [Pause.]

149:52:19 Gordon: Don, say again. You were cut out.

149:52:22 Lind: Roger. We've got a consumable update for you. RCS total is 47.6, Alfa is 46.4, Bravo is 48.7, Charlie is 46.4, Delta is 48.7, and we show 2 minutes and 38 seconds to LM impact.

149:52:47 Gordon: Okay. Understand. And would you tell me when I should start on the secondary pro - propellants? On the secondary fuel.

149:53:00 Lind: Roger. [Long pause.]

149:53:15 Lind: 12, we'll get an estimate on that for you.

[Comm break.]
Public Affairs Office - "This is Apollo Control. We're now one minute 50 seconds from scheduled impact. One of our displays in Mission Control will be showing the seismic trace. Hopefully, we see a very clear indication of the LM impact on that trace. We would expect that to show on the 4th trace from the left, which is the short period data from the passive seismic experiment. Now 1 minute, 25 seconds from LM impact."

Public Affairs Office - "We're coming up on 30 seconds to impact. Guidance Officer reports the LM is going to attitude. Now we're getting good data from the Lunar Module at this time and of course we'd expect that - all that data to go blank at impact."

Public Affairs Office - "10 seconds to impact."

149:55:13 Lind: Countdown for LM impact. 3, 2, 1...

149:55:18 Lind: Mark.

149:55:21 Lind: LM impact.

149:55:28 Conrad: Okay, thank you. [Long pause.]

Public Affairs Office - "And we've lost data from the LM indicating we impacted on time."

149:56:02 Bean: Houston, Apollo 12.

149:56:04 Lind: Go.

149:56:07 Conrad: Would you like to take the E-memory dump?

149:56:10 Lind: That is affirmative.

149:56:16 Conrad: It's on its way.

149:56:18 Lind: Roger.

149:56:33 Conrad: And, Don, we want to report the crew status report. Everybody is feeling fine. No medication today. There's been enough excitement.

149:56:44 Lind: Very good. Copy that.

149:56:46 Conrad: And the onboard readouts, Houston - the onboard readouts - those three batteries are still at 37.1. And the rest of our transmission has been taken care of.

149:57:10 Lind: We got 37.1. Will you give us the end of that?

149:57:18 Conrad: That's all three of my batteries. Battery C, Pyro A, and Pyro B.

149:57:22 Lind: Roger. Understand fox all batteries. Also would you give us a word about the CO2 cartridge, secondary? We were wondering why you'd gone to Secondary, if you had any other trouble on that? Apollo 12, that was the LM cartridge we were talking about. If you'd had another glitch on the CO2 sensor. [Long pause.]

149:58:42 Gordon: And, Don, since our High Gain is acting up like it is, do you want us to go Omni - Omni Bravo tonight?

149:58:50 Lind: This is affirmative. Omni Bravo. That's Omni Bravo when you configure for sleep, and we'd like you to put the normal S-band voice to Off at that time."

149:59:10 Lind: Roger.

149:59:13 Lind: One question. We were wondering if the sequence camera had been wrapped when you stowed it for – to prevent damage. Your choice as to where you want to stow it.

150:00:10 Lind: Apollo 12, would you hold what you have on attitude until we finish this E-Mod dump? [Long pause.]

150:00:51 Lind: Dick, for the RCS, we're 25 pounds on each quad above the level at which we'd open the secondary. So, things are okay there.

150:01:05 Gordon: Okay. I won't worry about it tonight.

150:01:07 Lind: Roger. [Long pause.]

150:01:19 Lind: Apollo 12, for your information, all the surface experiments for ALSEP are in great shape. They're all operating very well. There is apparently no temperature degradation at all because of any dust. So, that looks like that came out real fine. The passive seismic is working fine. It - noticed Pete walk past. Also got a very nice trace for your Lift-Off. On the LM impact, we were probably about 40 nautical miles away. So, the short period didn't get anything, but it looks like the long period got a couple of signals. Also, the cold cathode gage could see the sublimator walking past, Pete, when you went over to check the SIDE experiment, and all the other experiments are working fine. So everybody is absolutely delighted with the way you deployed the ALSEP. The passive did record the impact on long period.

[Comm break.]
150:03:04 Lind: Apollo 12, Houston. Before you close out the LEB, we'd like to just remind you to zero the optics, and we'd like you to leave the power on so that we can watch the CDU's [Coupling Data Unit] tonight. We've seen just a couple of glitches, and we just want to follow through on that and see how they're doing.

150:03:30 Gordon: They're doing fine.

150:03:32 Lind: Very good.

Public Affairs Office - "This is Apollo Control. The spacecraft is now gone behind the Moon. We will be reacquiring in about 45 minutes. The Apollo 12 Science Briefing is scheduled to begin shortly in the News Center auditorium in the small briefing room in building 1. The briefing will be conducted by principal investigators, Apollo 12 principal investigators. At 150 hours, 24 minutes this is Apollo Control Houston."

Public Affairs Office - "This is Apollo Control at 151 hours, 23 minutes. We passed the point of acquisition about 13 minutes ago. We have not established communications with the spacecraft on this revolution. The crew is scheduled to be sleeping at this time. CapCom, Don Lind has been putting in periodic calls to the crew. We do not believe that they are asleep at the present time, and we're in the process now of attempting to reestablish a usable Omni antenna, and its signal long with the spacecraft. The Flight Dynamics Officer has recomputed the landing point of the LM ascent stage. The recomputed impact point differs very little from the previous estimate. The latest estimate of the landing point is 3.95 degrees south, 21.17 degrees west. This would be about 36 nautical miles East of the planned impact point, and about 14 nautical miles South for a total of about 39 nautical miles East, Southeast of the planned impact point.

Public Affairs Office - "This is Apollo Control. We, as you heard, have not had any success making contact with the crew and getting the proper Omni antenna selected, so that we can reestablish communications. The next step will be to send a radio signal to the spacecraft which will trigger the master alarm in the cabin giving the audio tone also to the headsets. The rationale in reaching this decision at this time was to, if necessary, to awake them as early in the sleep period as possible, to reestablish corn rather than continuing to try to get through to them and get the proper Omni antenna selected and perhaps interrupt their sleep, after they're more soundly asleep later."

Public Affairs Office - "This is Apollo Control at 151 hours, 32 minutes. We are sending the radio signal at this time, which would trigger the flashing alarm light on the display console and also send a tone to the headsets. The best guess that we have at this point is that the crew was, after a long day quite tired as they went behind the Moon. Perhaps beginning the sleep period on the back side of the Moon. We want to of course, reestablish communications and do that as early in the sleep period as possible so that decision was made to attempt to arouse them at this time. Get communications reestablished on the Omni antennas, and then allow them to go back to sleep."

"

Public Affairs Office - "This is Apollo Control at 151 hours, 54 minutes. We're continuing at this time to attempt to reestablish communications with the spacecraft and presumably to awaken the crew. The last look we had, at the CSM prior to LOS on the previous revolution, everything looked good. The crew was, we expect, quite busy at that time. We should be on Omni B at the present time, we suspect that the spacecraft is configured for Omni D, which is not oriented in the proper direction for us to get sufficient signal both uplink and downlink for a lockon. The 210-foot Dish at Goldstone, California is receiving the signal from the spacecraft. However, it is not sufficient signal strength to allow us to establish lock. We have about 27 minutes now before the spacecraft again goes behind the Moon and we will continue through radio signals which would activate the flashing light and tone in the headset and also by calls from the CapCom to reestablish communication. There is no concern in Mission Control at the present time. However, the situation, principal concern is to awaken the crew, if that is what is necessary as early in the sleep period as possible to avoid disturbing their sleep any more than necessary. At 151 hours, 56 minutes, this is Apollo Control continuing to standby."

152:03:45 Lind: Hello, Apollo 12.

152:03:50 Conrad: What do you want?

152:03:51 Lind: We were just a little concerned about letting you go for 8 hours without any Comm. We're sorry to interrupt your sleep, but now we've got you back in Comm, so we're just going to wish you a good night and sorry for the interruption.

152:04:05 Conrad: Okay. We're not sleeping. We're all just trying to get clean in here; so, we had the Comm off. We'll be back with you after a while. Don't panic.

152:04:14 Lind: Roger. No problem. It's just that we had no TM or anything. We didn't want you to go to sleep before we got a hold of you.

Public Affairs Office - "Our Guidance and Control Officer reports the spacecraft is in the proper attitude for the sleep configuration. At a stable attitude and we are continuing to try to get some reaction out of the crew stowed away and getting ready for their sleep period and had the communications circuit off. We now have good solid lock on. Continuing to get data, and we expect that the crew will be beginning their sleep period shortly."

Public Affairs Office - "This is Apollo Control at 152 hours, 12 minutes. Our communications engineer has just reported that the crew has begun configuring their communications for the sleep period, and we expect that they will be getting to sleep before too much longer. The Flight Plan called for the sleep period to begin at 150 hours, about 2 hours ago. Pete Conrad reported that they were getting things cleaned up. Apparently the crew was a bit dirty after their Extra Vehicular Activities and getting the spacecraft – their equipment cleaned and stowed. We had reacquired or had the spacecraft come around in front of the Moon in position for a reacquisition at 151 hours, 9 minutes. At that time, the spacecraft communications system was apparently configured so that the Omni antenna - the active Omni antenna was not pointed in the proper direction for us to receive or to transmit to them. The original thinking was that the crew had probably configured for sleep on the back side of the Moon, and come around in front with the - improper Omni antenna. At 151 hours, 29 minutes, after several attempts to establish communications via the Capsule Communicator, Flight Director, Glynn Lunney, gave the order to transmit a signal to the spacecraft which would activate the alarm system on their display panel, flashing a light and feeding a tone into the headset. Apparently the weak signal strength which we had both down from the spacecraft and up to it, did not allow us to get that alarm in, and we apparently never triggered the alarm. At 152 hours, 2 minutes, we again established a lock on through the Omni antennas with the 210-foot antenna at Goldstone, California, and about one minute later, Pete Conrad responded with a hello and wondered what we were calling about. In reconstructing the situation, apparently the crew had the communications configured on in the spacecraft. We were not able to get to them to get the proper Omni for data, and had neither data nor voice communications. At this time, we are getting good data a high bit rate data through the Omni's and the High Gain – the large 210-foot antenna at Goldstone, and it appears that the crew is at this time getting prepared for their sleep period."

Public Affairs Office - "And the large 210-foot antenna at Goldstone and it appears that the crew is, at this time, getting prepared for their sleep period. We have some 7 minutes left before Loss Of Signal again, as Apollo 12 goes behind the moon on its 35th revolution. At 152 hours, 15 minutes, this is Apollo Control, Houston."

Public Affairs Office - "This is Apollo Control at 152 hours, 22 minutes. We have just had Loss Of Signal now. The spacecraft at the time of LOS looked good. The crew was configuring at that time for their sleep period and we expect they will be getting to sleep on the back side of the moon. Prior to reacquisition - we will next hear from the spacecraft after next acquire, in about 45 minutes. At 152 hours, 23 minutes, this is Apollo Control, Houston."

Public Affairs Office - "This is Apollo Control at 153 hours, 8 minutes. We have just acquired the spacecraft now in its 36th revolution of the Moon. We expect the crew will be asleep at this time. We'll stand by, briefly to see if we get any calls from the spacecraft. At the present time, Apollo 12 is in an orbit with apoloune of 60.2 nautical miles and a perilune of 53.9. The combined weight of the – the CSM weight rather is 35,627 pounds."

Public Affairs Office - "This is Apollo Control. We're getting good high bit rate telemetry data at this time from the spacecraft. The crew now in there sleep period. We don't expect any further conversation from the spacecraft until the sleep period ends at 157 hours, 30 minutes. We'll be prepared to come back up should we get any calls from the crew. In the meantime, we'll be taking the circuit down and continuing to monitor. At 153 hours, 19 minutes, this is Apollo Control, Houston."

Public Affairs Office - "This is Apollo Control at 154 hours, 22 minutes. We've had Loss Of Signal now from the spacecraft on its 36th revolution of the Moon. We'll be reacquiring in about 45 minutes. We had no conversation with the crew on this revolution as we expected. They're in their sleep period. That sleep period is scheduled to end at 157 hours, 30 minutes or a little over 3 hours from now. All spacecraft systems were looking normal as we lost contact with the spacecraft as it went behind the Moon. Biomedical data indicates the crew asleep. At 154 hours, 22 minutes, this is Apollo Control, Houston."

Public Affairs Office - "This is Apollo Control at 154 hours, 58 minutes. We're about 8 minutes, 30 seconds now from reacquiring the Command Module on it's 37th revolution of the Moon. We have a little over an hour and a half left in the sleep period - correction about 2 and half hours. That sleep period's scheduled to end at 157 hours, 30 minutes. There will be a Change Of Shift briefing in the Houston news center in about 15 minutes. Flight director Clifford Charlesworth is coming on to replace the Black team of flight controllers headed by Glynn Lunney. The Change Of Shift briefing will include Flight Director Glynn Lunney, also the Flight Dynamics Officer for this shift, Jay Greene and the Capsule Communicator, Astronaut Don Lind. We estimate that will begin in about 15 minutes. At 154 hours, 59 minutes, this is Apollo Control Houston."

Public Affairs Office - "This is Apollo Control 156 hours, 8 minutes Ground Elapsed Time. Ten minutes until Loss Of Signal in the 37th lunar revolution. The crew is still asleep at this time, some 1 hour, 21 minutes remaining in the scheduled sleep period. Present orbit approximately 62.6 by 57.6 nautical miles apolune and perilune, respectively. At 159 hours and 4 minutes, slightly under 3 hours from now, the crew is scheduled to do a 380.5 feet per second Service Propulsion System maneuver out of plane to the North which will drive the orbit back over these photo sites which will be photographed later tomorrow morning. These are candidate-landing sites for future Apollo missions. The Fra Mauro formation, Lalande and one other area which escapes my memory at the moment. Descartes, there you go. And at 156 hours, 9 minutes, Ground Elapsed Time, this is Apollo Control."

Public Affairs Office - "This is Apollo Control 157 hours, 23 minutes Ground Elapsed Time. We have had acquisition now for about 15 minutes on the 38 [th] revolution. The crew still has about 5 minutes remaining in the scheduled sleep period, however it has been noticed on the ground that the High Gain antenna angels have been changing in the last few minutes and we are anticipating a call from the crew, surgeon says that the 2 crewmen who have bio-medical instrumentation during the sleep period are awake at this time. So we will leave the air to air to ground circuit uplive to catch the first exchange this morning."

157:39:10 Gibson: Roger. Reacq. [Long pause.]

157:39:47 Gibson: 12, Houston. Would you like some information on the crater which you made?

157:39:55 Conrad: Yes.

157:39:58 Gibson: Okay. The location is South 3.95 and west 21.17 and that's, relative to the Surveyor, 36 nautical miles east and 14 nautical miles South. And you will he able to see that on your - where the actual location is - on the South-Western edge of the circle for target of opportunity 39. Your velocity at impact was 5,502 and you came in at the angle of about 3.8 degrees relative to local horizon.

157:40:46 Conrad: Hey, give me the Lat-Long again.

157:40:50 Gibson: Roger. That's 3.95 South, 21.17 West, and we did pick that up on the PSE. We've got some long-period oscillations from it. They lasted on the order of 40 to 50 minutes.

157:41:09 Conrad: Good. [Pause.]

157:41:17 Gibson: 12, the computer is yours.

157:41:23 Gordon: Thank you.

157:41:31 Gibson: Pete, Houston.

157:41:36 Conrad: Go ahead.

157:41:39 Gibson: Okay, Pete. You can dispense with the bioharness, and we have some recommendations for you if you feel you need it for clearing up some of the skin irritation.

157:41:53 Conrad: Okay. It goes away as soon as I take it off. The one that I have is all dried up now, that I can move, so go ahead with your recommendation.

157:42:07 Gibson: Okay. We recommend you consider the following: one, wash thoroughly around all sensitive locations with the wetwipes; you then remove bio-sensor and harness; wash the skin in those areas with wetwipes and let dry; apply the skin cream to the infected areas twice daily; and apply no bandages over the irritated areas; and, in drying, just let it dry in the air.

157:42:41 Conrad: Okay. Thank you.

[Comm break.]
157:44:01 Gibson: Apollo 12, Houston. Would you give us the shaft key pack reading and also whether you see any oscillations?

157:44:23 Conrad: The trunnion is reading 35.9 and the shaft is reading 0.4 and it's oscillating between 3599 and 0.5.

157:44:46 Gibson: Roger. And thank you. We are seeing deviations at a half of a degree down here.

157:44:53 Conrad: That's about right.

157:44:57 Gibson: Roger. Would you take the optics-coupling switch to Direct and see if it stops? [Pause.]

157:45:16 Conrad: That seemed to do it.

157:45:19 Gibson: Roger.

[Comm break.]
157:46:49 Gibson: 12, Houston.

157:46:54 Conrad: Go ahead.

157:46:55 Gibson: Say, it looks as though it's - it would be possible for you folks to do some photography on the impact, or the crater which you folks made with the Ascent Stage. We can give you an idea of what the procedure would involve, and you can use your own discretion as to whether you want to try it.

157:47:17 Gordon: What are you thinking of using to take the pictures, Ed? [Long pause.]

157:47:37 Conrad: Also, Houston, the shaft is still oscillating a half degree here in the Direct.

157:47:43 Gibson: Roger. Okay. You'd be using the 250-millimeter lens, and it'd be hand hold hand held out the hatch window. If you'd like, I can read you up a quick summary of the procedure.

157:48:08 Gordon: Let's see; the procedure's not necessary. Give me the gimbal angles and the time and what window.

157:48:23 Gibson: Okay. What you do is immediately follow in the Lalande high-resolution photography on Rev 39 which appears to be the best place to pick this up. You'd stop your pitch rate and do a 20-degree roll left. Impact point will be visible out the hatch window, 22 miles south of track. TCA would be 159:47:23, and we've already given you the information of where it appears on your target of opportunity map. You would remove the camera from window 4, change to 250-millimeter lens and hand hold out the hatch window and the following settings would apply: F:5.6 and 1/125. And you can take several shots.

157:49:23 Gordon: Okay. I've got after Lalande photography, stop pitch, 20-degree roll left; TCA is 159:47:23; 250-millimeter lens; F:5.6 and 1/125.

157:49:40 Gibson: That's right. That's 1/125th.

157:49:46 Gordon: Roger. And that was out of the window number 5? Or the hatch window?

157:49:53 Gibson: That's affirm. Out the hatch window.

Ignition - counting down to ignition for the Plane Change maneuver some 47 minutes and 5 seconds until that maneuver. And at 158 hours, 17 minutes, Ground Elapsed Time, this is Apollo Control."

Public Affairs Office - "This is Apollo Control, 159 hours, 2 minutes Ground Elapsed Time. Less than a minute away from acquisition as Apollo 12 comes out from behind the Moon on the 39th revolution. At some 2 minutes, 14 seconds until ignition for the SPS Plane Change maneuver coming up at 159:04. As mentioned earlier this 381 foot per second out of plane maneuver will drive the spacecraft orbit back over the potential landing site for future Apollo Missions. These landing sites will be photographed with considerable detail by the crew. We should have acquisition now. We'll stand by for the first call."

159:29:00 Gibson: Pete, that's on the South edge, directly on the South edge of the circle.

159:29:11 Conrad: Okay. It indicates on the map, there, that there's a sort of a ridge running along there. Is it on the East side of the ridge or on the West side of the ridge?

159:29:30 Gibson: Stand by.

161:12:32 Conrad: We got Dick working this pass and Al and I are sightseeing. This is really the first chance we've had to get a good look at the Moon; so, we're enjoying this pass with the map, checking off all the craters.

161:12:49 Gibson: Roger, Pete. Understand. Does it look any different after being down there; you get a little better feel for what it's like?

161:13:00 Conrad: Well, I - I think so. Of course, the back side back there doesn't really look anything like what we were on.

161:13:11 Gibson: Roger.

161:13:20 Bean: I personally think, Ed, it's more spectacular from orbit - that you can see all these gigantic craters and the - and - the - all diameters of the Moon and its change in color. When you get out on the surface - it's interesting down there, naturally, but it's not too much unlike just being out in a big field of clumps on Earth.

161:13:47 Gordon: You haven't got any of these craters around it.

161:13:48 Bean: Not that - not that much difference - than on Earth...

161:13:53 Gordon: [Garble] at the right place.

161:13:55 Bean: ...and, of course, you can never see anything like this - [garble] down hers.

161:14:08 Gibson: Do you think that will satisfy Dick?

161:14:15 Bean: No, he keeps talking about making a low pass over the landing site before we go.

161:14:22 Gordon: And I may get another chance; you can't ever tell.

161:14:26 Gibson: Hope so.

161:14:37 Gibson: You mentioned that back side looks different; is it - just a different crater density or entirely different nature to it?

161:14:50 Conrad: Looks like different nature to me. [Pause.]

161:15:11 Gibson: 12...

161:15:12 Bean: The back side, like everyone said, is - Go ahead, Ed.

161:15:17 Gibson: No, go ahead, Al.

161:15:23 Bean: I was just going to say, it's just like everyone said before, the back side is a lot more worked over, a lot more - worn and smooth; and where the front side's got all these Mare areas, a lot more contrast and a lot more sharp features to look at. I personally like to look at the front side, the Rilles and the - the higher mountains; the contrast between that and the Mares to me is more interesting.

161:15:57 Gibson: Roger. Probably that Sun angle has a lot to do with how treacherous some of those mountainsides look.

161:16:10 Bean: That's right, Ed, because on the back side here, there's no flat area at all; it's all just [garble] and big craters, little craters - no real sharp contrast between flat and high mountains or anything like that.

161:16:56 Gibson: That must have been an interesting approach going down there; you had some pretty steep - [garble] you were flying over there at pretty shallow Sun angles.

161:17:10 Conrad: You mean the PDI?

161:17:12 Gibson: That's affirmative.

161:17:16 Conrad: Yes. Well, at first, we - we - The last time I saw it coming up on PDI, it looked like we were really augering in and going through some mountains, but I was kind of occupied, watching the descent in the cockpit there, and when we pitched over and I first looked, I didn't have the foggiest idea where I was; and then, all of a sudden, the old pattern was sitting right there.

161:17:46 Gibson: Just like the Cape, huh?

161:17:47 Conrad: Yes, I was just a - and then I did a little LPD and - Yes, Just like it; and I did just a little LPDing mainly to - would you believe it, to get out of the crater, not to get to it, because it looked like we were going to land right smack on the [garble].

161:18:07 Gibson: We've got a FIDO down here, telling me about a prediction of l0 feet.

161:18:10 Conrad: Hey, - Well, for all I know, he could be right because it sure looked like we were going right in the middle of the crater. [Pause.]

161:18:42 Bean: Another beautiful sight, Ed. Headed down from DOI to PDI; we'd already entered the PDI attitude, and just at the part of the [garble] where that would make us [garble] vertical [garble], at that time, an Earthrise occurred, and really a fantastic sight. It occurred very rapidly up here like [garble] said, and it's just such a fantastic view of a blue and white shiny ball, [garble] it's about one-third of a ball, compared to sort of a drab gray or brown or whatever color you can call the Moon. It's – a spectacular sight.

161:19:23 Gibson: Roger, Al. Say, you're a bit broken up. Why don't you try moving the mouthpiece? [Pause.]

161:19:37 Bean: Will do, Ed. [Pause.]

161:19:50 Gibson: 12, we have a little lunar news for you if you’re...

161:19:52 Bean: You know the only sight that I saw...

161:19:53 Gibson: ...interested.

161:19:56 Bean: Okay.

161:19:58 Gibson: Okay, Pete and Al and Dick, you got a Central Station down there; the power is good, and you got a good signal. Average temperature now is about 72 degrees, and it's slowly increasing about 0.6 degrees per hour. The biggest thing that happened recently was the impact of the ascent stage and the PSE picked that up very well. They consider that one of the most significant things that's happened to date on lunar seismology. The LSM is working real well. They just did a flip Cal on it, and they did the flip Cal before ascent. And they also noted at ascent that the magnetic field blanked out at ignition and lasted - the blankout lasted for l0 to 12 minutes after. The solar wind has its covers off and is perking right along. The SIDE also picked up some counts in the high energy range of the detectors at ascent. And they also think they have a probable pickup of the impact itself. However, the SIDE is still - continues to short out occasionally, and they think it's just degassing; so now, they have the high voltage off, and they'll probably bring it back on around lunar noon. Other than that, it looks as though it's really perking right along; you did a swell job.

161:21:25 Conrad: Hey, Ed. What - What's their best estimate now of the effect of all the dust it got on it? The pieces of equipment we laid down there?

161:21:39 Gibson: Okay, from what we can see down here, there's no observable effect.

161:21:47 Conrad: Oh, that - that's going to be very interesting, because - I wonder what happened to the EASEP then - because, obviously, you couldn't have blown - 11 couldn't have blown any more dust on that EASEP than - than we got on our ALSEP and –that thing really got dirty. It got into the [garble] we needed and everything else. You just can't help but get them real dirty. Oh, it's not that dirty, but [garble] had a fair amount of dust on it.

161:22:19 Gibson: Roger, Pete.

161:22:20 Conrad: You can see from our pictures when we get them back just exactly how dirty it was.

161:22:27 Bean: Yes, I was going to say a minute ago, Ed, the only other sight that I thought was more spectacular was ascent from the Moon. And when that thing's ready to bang and stage, it started straight up, and actually goes pretty fast – I was a little surprised. And it pitched over so far, I could look straight down and see the descent stage and see the ALSEP - see that we hadn't knocked over any parts of the ALSEP; it didn't look like anything big was being blown that way. I had the camera mounted in the window, pointed - you know, pilot's eye view. Instead of pointing down, like [garble], I just had it mounted on the window pointed straight ahead, and it would have caught the same view we were getting only the thing stopped some time, and I'm not really sure when, and I'm just hoping that it didn't stop before we lifted off and made that pitchover, because that'll be spectacular to look at on the movies. I started it again a couple times, as you know, during the ascent and it still shut down - it worked all the time during the descent but something happened.

161:23:30 Gibson: Roger, Al. Sure hope you did catch that. Yes, that was a concern perhaps of that SIDE being pretty susceptible to tipping over there, especially from anything blowing out on the – from the ascent itself. Glad to hear it didn't.

161:24:35 Conrad: Well, I'll tell you one thing, Ed. You and Joe and all the guys put together a great lunar surface LM; that thing went without a hitch.

161:24:45 Gibson: Well, I think you guys were the prime movers from the beginning and the hitches that did come up, you sure knew how to work around them. Well done.

161:24:56 Conrad: Anybody can swing a hammer.

161:25:44 Gibson: 12, Houston. We're standing by with a map update for Rev 41, TEI PAD, Rev 43, and some times for high-resolution photos Descartes and Fra Mauro.

161:26:03 Gordon: Okay. We're ready to copy.

161:26:07 Gibson: Map update, Rev 41: 162:13:27, 162:38:38, 162:59:49; TEI PAD, Rev 43, SPS/G&N: 34235; minus 0.64, plus 0.24; 168:28:52.72; Noun 81, plus 2944.7, plus 0271.9, minus 0079.0; NA, pitch is 126, and NA; four jets; 11 seconds. Read back.

161:27:13 Gordon: Roger. On AOS/LOS, 180, I got that.

161:27:21 Bean: And the TEI PAD is SPS/G&N: 34235; minus 0.64, plus 0.24; 168:28:52.72; plus 2944.7, plus 0271.9, minus 0079.0; NA, 126, NA; four jet; 11 seconds.

161:27:44 Gibson: That's Charlie. And we've got times for...

161:27:48 Bean: Roger-Roger.

161:27:50 Gibson: ...we have your times for high resolution photos on Descartes and Fra Mauro, when you're ready.

161:27:58 Gordon: Go ahead. Ready to copy.

161:28:01 Gibson: Okay. Descartes, T-1, 163:29:12; T-2, 163:33:12; roll, pitch and yaw, you can use the attitudes in the Flight Plan. Fra Mauro, T-1, 163:40:01; T-2, 163:44:01. And again, roll, pitch, yaw angles are the same as in the Flight Plan.

161:28:38 Gordon: Roger, Ed. Copy 163:29:12, 163:33:12; for Fra Mauro, 163:40:01, 163:44:01; and the R, P, Y as in the Flight Plan.

161:28:52 Gibson: That's correct. [Long pause.]

161:29:49 Gibson: Pete, Houston.

161:29:56 Conrad: Go ahead.

161:29:57 Gibson: Say, in looking over the transcripts of the EVA, Uel figures you saw some pretty interesting stuff down there. As a matter of fact, he figures about 11 times.

161:30:09 Conrad: Okay. Very good. That's not too bad for 8 hours.

161:30:18 Gibson: That's for sure.

161:30:27 Conrad: You learn how to be a test pilot by not committing yourself.

161:30:33 Gibson: Say again. You were a bit broken.

161:30:38 Conrad: I say, you learn how to be a test pilot by not committing yourself. It's called "weasel wording."

161:30:49 Gibson: Guilt by association.

161:31:44 Bean: We're passing over the crater Kant right now, and it has a large impact crater in the middle of it that's got rocks so big in it that I can see them with my naked eye laying down there; so, they got to be awful big.

161:32:07 Gibson: Must be looking at chunks of the real bedrock.

161:32:14 Bean: Yes. And from here - of course, this is a bright impact crater, and the rocks laying out there are pure white in contrast to a rather dull gray sort of texture of the rest of the crater Kant.

161:32:34 Gibson: Roger. You made that comment also on the surface about some of those which were pure white. Do you think that was just the Sun angle or do you think that's the real color?

MP3 Audio Clip GET 161:32:44 to 160:33:54 [ 01 mins 41 sec]

161:32:44 Bean: Well, I don't know - I guess we're about high noon now, wait a minute - we're at high noon now, and it may be the Sun angle because we, of course, were sitting on the surface and the Sun was relatively low, shining across at those blocks. But no matter now you slice it, anywhere along in here, no matter what the Sun angle is, these gray craters appear to be white, like chalky color, with blotches on them. As a matter of fact, we're passing over a bunch of them now, and I can see boulders with my naked eye, and I can see them real clearly with the monocular.

161:33:41 Gibson: That would make a very spectacular descent from low gate.

161:33:54 Bean: Yes. And also...

161:42:38 Conrad: Okay, Ed. Just looking at the Flight Plan and noticed what time it was back there. How come you get all the good deals?

161:42:47 Gibson: Well, it's a good deal. I'd rather be up when you're up than be watching you sleep during the day.

161:45:46 Gibson: Okay, that's much better. Say, on that question you brought up before about the - having that hot engine and looking at the return. If we did it the way you suggested, we'd be...

161:46:01 Conrad: Wait just a second, Ed.

161:46:02 Gibson: Okay. [Long pause.]

161:46:34 Conrad: Okay, Ed. Go ahead. Sorry, we were trying to - Al and I were trying to pick up this Snowman from here.

161:46:41 Gibson: Did you get him?

161:46:46 Conrad: Yes. I got him in the monocular.

161:46:48 Gibson: Okay. On the question you brought up before, it looks as though your Delta-V capability would be around 20-feet-per-second margin, and that looks a little bit small.

161:47:01 Conrad: Okay. No problem; we weren't sweating it. We just knew that if we had a better engine or something, why, there was a chance that we might have enough to do it. No problem at all.

161:47:17 Bean: That's 1 less day in the LRL, Ed.

161:47:21 Gibson: That's right. I think you probably got a little better place to spend it there.

163:01:03 Carr: Kind of nice to kind of get back away from it and look at it from a distance, huh?

163:01:09 Bean: Yes. We had - We didn't get a chance before we went down to look at it. We always had something going on, and as a result we just got glimpses. We got a couple of glimpses there when we've been heading down and taking some photographs. We haven't had to monitor any too closely because they've been done every 20 seconds by the intervalometer and we've been able to look out the window.

165:43:13 Gordon: This last one, Fra Mauro 1.

165:43:16 Carr: Okay. Dick, while I have you, sometime on the back-side pass here, I think you can expect to see the manifold pressure on RCS quad C start to dis - decrease, meaning that you've depleted your primary tank. We'd like you to switch to secondary on that quad only. All right?

165:43:39 Gordon: Okay. Secondary on C only. Thank you.

166:10:16 Gordon: Hey, Jerry. Al just put in a comment about starting these a little early. I felt that I had to, because that last mark the target is going out of sight; that's because our field of view in the telescope isn't as much as it is in the sextant, and I think you've got to start a little bit earlier than 40 seconds after T-2. I've done that purposely. Any comments?

166:58:11 Carr: Yankee Clipper, Houston. How do you read me now?

166:58:16 Conrad: Roger. Loud and clear. Listen, Jerry, I've got something real important for you. We were taking some target of opportunity photographs with the same film pack that we had the 500-millimeter film on, and without going into details right now - I'll tell you later when we have the time –that magazine pack popped off and we're not sure we didn't wipe out that film magazine. Now, what we suggest is that - is we dump the landmark tracking, seeing as we got good ones last time on Descartes and Fra Mauro and you pump us up another T-1 and T-2 for both of them and let's get some more 500-millimeter this pass on another magazine. Okay?

166:59:10 Carr: Roger, Pete. We copy. Stand by 1.

166:59:16 Conrad: Okay.

167:02:51 Conrad: Go, Houston.

167:02:52 Carr: Roger. We concur with your plan, Pete, and we're hustling right now to get some new T-1, T-2 times for Descartes and Fra Mauro.

167:03:03 Conrad: Okay. Let me tell you what happened. We - Al was very careful to watch all the time we were taking the 500-millimeter pictures to - to make sure that the camera was, in fact, running; and he was watching the side opposite the counter which is at the - the little red-and-white deal; and, and, and - I mean, he was watching the red-and-white thing as we were taking the picture and we noticed that we [garble] 500-millimeter indicated approximately 100 pictures but the counter only read 60 and we kicked that around for quite a while until we finally concluded that, because Al had been watching, that - that there was something wrong with the counter and we really had taken all the pictures. So we decided that we'd use up the rest of that film on targets of opportunity; so while Al was taking the pictures out the window, the side of the magazine just popped off out of nowhere for no reason, and it opened up about an eighth of an inch, and Al tried to get it back on and then he had to actually open the lock and put it back on. Oh, we never did get it on, so he just taped it on, and we don't know whether it's light-struck or not and we don't know why it - it popped open, but we're sure suspicious. We also don't know if it – if it was only partially on to begin with that we really did lose film; so I think it's best that we take a fresh magazine, which he has, and we'll get those pictures again.

167:04:56 Carr: Roger, Pete. That sounds like the best way to go.

167:05:02 Conrad: Okay. We do.

We've had a meeting of the minds here, and the tentative plan right now is to drop the stereo photos on, stereo strip work on Rev 44 because it has a lower priority than the landmark tracking, and so we want to be prepared for landmark tracking on the next Rev. We'll have PAD data available for you by AOS, and what we are going to have to do now is uplink you a new state vector and have you do a P52 on this pass. Over.

167:51:25 Conrad: Okay. What you want is Fra Mauro, Descrates landmarking tracking. Is that right?

167:51:29 Carr: That's affirmative, Pete.

167:53:11 Conrad: Hey, Houston; Yankee Clipper here. Why don't we start ,he last test during the stereo strip and we'll grab Lalande in the middle of it, and we can get it all that way.

167:53:26 Carr: That sounds like a sterling proposal, Pete.

167:53:31 Conrad: Okay. We'll do that on the last Rev, and we'll break right in the middle there just before T-1, grab Lalande and go back to it. And that'll take care of the whole show. [Pause.]

167:53:59 Carr: Clipper, Houston. You mentioned Lalande, and that confused us. Say again.

167:54:08 Conrad: On the very last Rev, we want to photograph Lalande with the 500-millimeter.

167:54:17 Carr: Roger. We're with you now.

167:54:22 Conrad: Okay. So what we need from you is the T-1 and the times for Descartes and Fra Mauro. We'll get them next pass. And then we need a T-1 time for 500-millimeter on Lalande on the next pass, which is the pass we burn TEI on, and we'll stereo strip her up to that point. Rev Lalande, keep on going with the stereo stripper and burn TEI around the corner.

167:55:07 Carr: Stand by, Pete. Clipper, Houston. The computer is yours.

167:55:19 Conrad: Okay. And we'll give you a P52 in about 2 minutes here. [Long pause.]

And they're all waiting anxiously for all three of you to get back. Dick, Barbara said you're doing a fabulous job but she sure wishes you could get some rest, so she could. And, Al, Sue says she spent the evening with Jane, and they had a lot of fun last night, and they both feel real good about everything. And she's now in a watching-and-waiting mode.

We think that might squeeze some of the targeting near the end there, and we ~ we think you'd be better off if you did your stereo strip work on Rev 44. I have some T-1 and T-2 times for you.

168:02:37 Carr: Clipper, Houston. The plan is to do your stereo photos up until the landmark tracking time, and then terminate the strip photos and do your tracking.

168:02:56 Gordon: Okay, Jerry. Give me the T-1 and T-2 times for Descartes, Fra Mauro.

168:03:03 Carr: Okay. Terminate your battery B charge. And your stereo photos for Rev 44 are T-1 of 168:54:00, 169:10:00, and we'll have your T-1 and T-2 times for - at AOS for your other work.
