This is Apollo Control at 155 hours, 3 minutes. We said goodnight to Scott and Irwin aboard the Lunar Module on the lunar surface about an hour and 45 minutes ago. And passed along our goodnights to A1 Worden in the Command Module about one hour ago. And have had no further communication with either vehicle. We're still about 16 minutes away from reacquiring the Command Module, which at that time will be on its 40th revolution of the Moon. The heart rates, based on the biomedical telemetry data we're getting on Jim Irwin, indicate that he is resting comfortably and dozing, either asleep or very near asleep. And both spacecraft continue to appear normal in every respect. No - no outstanding systems problems at the present time and we're getting good data from the science - Lunar Surface Science Package, the ALSEP; and all the experiments there appear to be functioning well at the present time. We're getting very good signal strength also from the transmitter on the ALSEP. In the Scientific Instrument Module bay aboard the Command Service Module, we're getting good data from the - continuing to get good data from the orbital experiments being carried there. With the exception of a couple of problems which we've mentioned previously, all of the instruments there are functioning normally. The problems are with the Laser Altimeter which is used in conjunction with the Mapping Camera, and it appears that the Laser Altimeter is simply not getting enough return signal. It's below the threshold and that would appear to be the case at the present time, and we're more and more coming to suspect that we're not going to get usable data from the Laser Altimeter. The other problem is with the Mass Spectrometer and it's difficult, at this point, to say whether that's a real problem or a sensor problem. Worden has reported that on retracting the boom mechanism, the retraction does not appear to be occurring as rapidly as we would expect. And on the last revolution before he began his rest period, he reported that when he attempted to retract the Mass Spectrometer at the end of its 24-foot [7.3-metre] boom, the indicator in the spacecraft went part way closed but did not give him a solid indication that it had retracted. He recycled the switch a couple of times, extending and retracting. And we don't, at this point, know whether the problem was with the sensor or with the boom mechanism itself, and since Worden has no way of actually seeing the extended boom, that issue is still somewhat in doubt. The principal investigator for that particular experiment elected not to attempt to deploy the Mass Spectrometer at the last opportunity. There will be a time later in the orbital sequence where the Command Module will be in a more favorable attitude for deploying the Mass Spectrometer and the decision was made to attempt to redeploy it at that time. Again, to repeat the situation as far as the third extra-vehicular activity is concerned, Scott and Irwin began their rest period about 1 hour, 50 minutes behind the scheduled time in the Flight Plan, and since we have a rigid lift-off time, we do not plan to slip lift-off, and it will be necessary to have the crew back in the Lunar Module and beginning their preparations for lift-off at about 168 hours. With this as a kind of an upper limit then for the EVA, coupled with the fact that the rest period began late, we do not plan to awaken the crew prior to 7 hours of rest. That raises the distinct possibility that the EVA will be somewhere between an hour to an hour and one-half late getting started. This would place egress from the Lunar Module at about 163 to 163½ hours, assuming that the amount that we are behind in the Flight Plan for the Lunar Module and Scott and Irwin continues to hold at the same level it is at the present time. There is a possibility that some of this time can be made up in the preparations for the EVA after the crew is awake. There's also a distinct possibility that even though we do not plan to awaken Scott and Irwin before 7 hours, that they may themselves awake and decide to get up and get started. To cover these possibilities, we're continuing to plan for EVAs ranging anywhere from 4 to 6 hours, with the best estimate that the EVA will be about an hour late getting started. In other words - starting at about 163 hours and will last for about 5 hours. At 158 hours, 9 minutes; this is Apollo Control, Houston standing by.
This is Apollo Control at 156 hours. The Command Module has, just a few minutes ago, passed over the Hadley site on its 40th revolution of the Moon. Both crews are in the midst of sleep periods at the present time and the biomedical data that we have on Al Worden shows that he is soundly asleep. And Jim Irwin sleeping a little less soundly. Surgeon reports that he is at times dozing and at times perhaps just resting. We have some preliminary numbers on the total sample collected so far on the first two EVAs by Scott and Irwin. These are estimated weights based on numbers read back by the crew from the gross weights, the sample plus container, and the estimated net weight is obtained by subtracting out the known weights of the containers and equipment contained within them. These estimates are as follows; for the first EVA a total of 28.9 pounds [13.1 kg] and for the second EVA a total of 77.6 pounds [35.2 kg] giving us an estimated grand total for the first two EVAs of about 106.5 pounds [48.3 kg]. We, at the present time, have good solid telemetry data from both vehicles and both spacecraft appear to be normal. No problems at the present time. I will continue to monitor the systems on both spacecraft continuously on the LM and every revolution while the Command Module is in radio acquisition. We don't expect any further communications with either crew during the rest periods, and we'll have our release lines down except for periodic status reports. We are, at the present time, replaying the video tape of today's EVA, and that can be seen in the MSC News Center. At 156 hours, 3 minutes; this is Apollo Control, Houston.
This is Apollo Control. We're now about 3 hours away from the time we plan to put in a call to Dave Scott and Jim Irwin aboard the Lunar Module Falcon on the lunar surface, and get them started for their third and final period of extravehicular activity. Scott reported about 4 hours ago, that he and Jim Irwin were going to call it a day and try to get some sleep. This was about 1 hour and 50 minutes behind their regularly scheduled beginning of their rest period. And as we have mentioned, this undoubtedly will cut short the EVA, or at least raise the very distinct possibility that the EVA will be shortened most likely by about an hour. Throughout the evening in Mission Control, we've been working on a series of EVA plans which we would hope to have ready to present to the oncoming shift, Gold team of flight controllers, who will have responsibility for carrying out the EVA here in the Control Center. These EVA plans will cover the eventualities for EVAs ranging from 4 hours to 6 hours, probably in 30 minute segments. In other words we would have a plan for a 6-hour EVA, one for an EVA that ran 5 hours 30 minutes, 5 hours, 4 hours 30 minutes and 4 hours. The total time of the exploratory period would then depend on the time that the crew awakes and completes their EVA preparations. Both spacecraft continue to remain stable. We do not have radio contact with the orbiting Command Module at the present time. We're about 15 minutes away from reacquiring, but during the front side passes when we've had telemetry data, the Command Module continues to look normal as does the Lunar Module, and of course we have continuous telemetry data from the Lunar Module. At 157 hours, 3 minutes; this is Apollo Control, Houston.
This is Apollo Control. We're now about 2 hours, 15 minutes away from the time at which we plan to put in a call to the Falcon crew, Irwin and Scott if we haven't heard from them before that time, to begin their third EVA. At the present time, we have about 30 minutes before we lose radio contact with the Command Module. And we have not heard from either the Command Module Endeavour or Falcon since we said goodnight to both vehicles. We last heard from Scott and Irwin at 153 hours, 15 minutes; and our last conservation with Al Worden was at 153 hours, 54 minutes. The operation of the lunar science experiment package on the lunar surface continues to be normal for both the telemetry and the command links. A normal leveling command sequence was completed successfully for the Passive Seismic Experiment. And the Suprathermal Ion Detector in the - is in the standby mode. All other experiments on the ALSEP are on and sending back data. In Mission Control, at the present time, we're beginning to get some of the members for the oncoming shift. The shift handover is scheduled to occur in about 30 minutes at 11 pm Houston time. We expect that if the - if the crew is still sleeping at that time, and we do plan to allow them to continue sleeping if they desire, the shift handover will be in a more or less staggered process. A number of the flight controllers probably won't be coming in for an additional hour, if the crew is not awake at the Flight Plan time of 158 hours, 25 minutes. Flight Director Gerry Griffin will probably be coming in - in about an hour - hour and a half. So we'll have a somewhat staggered shift change here. We do not intend to have a change of shift briefing because of the staggered nature of the shift handover. We'll continue to stand by with the release line down until we get closer to the scheduled wake up time. Should we have any conservations with the crew or any indication that Irwin and Scott are stirring and beginning to get up and get prepared for the extravehicular activity, we'll bring the line up and stand by live at that time. At 158 hours, 4 minutes; this is Apollo Control.
This is Apollo Control at 159 hours. There have been no signs of activity at Hadley Base. Dave Scott and Jim Irwin apparently still asleep and it'll be about an hour and fifteen minutes before we plan to awaken them with a call from Mission Control. At this time, our best estimate as to a start time for the third EVA is about 163 hours to 163 hours, 30 minutes; about an hour to an hour and a half behind the scheduled time in the Flight Plan, which would give us a 5 to 4½-hour EVA. Most of the members of the Gold team of flight controllers are in the Control Center at the present time. Flight Director Gerry Griffin is preparing to take over from Flight Director Glynn Lunney. The Black Team will be going off now. And we're also reverting now to the dual Flight Director/dual CapCom status. Gene Kranz will be Flight Director for the Command Service Module and the SIM bay activities. The Command Module spacecraft communicator will be astronaut Karl Henize and Joe Allen will be coming on to relieve Bob Parker as spacecraft communicator for the lunar surface activities. The Command Module Endeavour is still about 13 minutes away from reestablishing radio and telemetry contact. Al Worden is not scheduled to end his 8¼-hour sleep period until 162 hours. At 159 hours, 2 minutes; this is Apollo Control, Houston.
161:59:36 Henize: Endeavour, this is the planet Earth calling. We'll start off the day this morning with a little bit of wake-up music for you. And if you appreciate our selection, you may respond with an E-memory dump, if you are able to hear me at the present time.
162:00:17 [Music: "Tijuana Taxi" by Tijuana Brass.]
162:00:26 Henize: Endeavour, this is the planet Earth calling this morning. We'll start off with a little bit of wake-up music and then we'll get into the day's activities. If you are awake enough to hear this, you can express your appreciation for our fine music by sending us down an E-memory dump. [No answer.]
162:02:18 Henize: Endeavour, this is Houston. How do you read now? [Pause.]
162:02:31 Henize: Endeavour, this is Houston. If you are reading give us Accept and we'll send up a state vector.
162:02:46 Worden: Allo, Terre. Salute de l'Endeavour.
162:02:51 Henize: Good morning, Al. How's the morning up there?
162:03:00 Worden: Well, I'll let you know when I wake up, Karl. I had another very peaceful evening.
162:03:07 Henize: Glad to hear it. [Long pause.]
162:03:34 Henize: We're ready for High Gain [Antenna to] Auto, Endeavour. And I have - and I have a Flight Plan update, the most important one being that, at 162:06, in about 3 minutes, we will delete - delete the "Gamma-ray [Spectrometer] Gain Step, Shield, Off."
162:04:10 Worden: Okay, Karl; understand. Let me get the Flight Plan out here.
162:04:25 Worden: Okay, "Gamma-ray Gain Step, Shield, Off" has been deleted.
162:04:28 Henize: Roger. And I have Mapping Camera photo PAD and some further Flight Plan updates when you are ready to copy.
162:04:38 Worden: Okay; go ahead.
162:04:41 Henize: Mapping Camera photo PAD down there at 162:55. T-start: 162:59:30, T-stop: 163:59:11.
162:05:13 Henize: That's correct, and further Flight Plan changes; we have very few today. At 162:16 we can delete the "Gamma-ray Gain Step, Shield, On."
162:05:28 Worden: Understand. 162:16; delete "Gamma-ray Gain Step, Shield, On."
162:05:33 Henize: Roger. Over on 163:10, we add "Map Camera, Image Motion, Increase" with appropriate barber pole comment. Increase, and then leave it on. "Increase/On" would be a better way of reading that to you.
162:06:02 Worden: Okay; understand. At 163:10, you want the "Image Motion, Increase to barber pole and On."
162:06:08 Henize: Roger. And at 163:40, we can add, "Mapping Camera, Image Motion, Increase/On." And also, "Gamma-ray Gain Step, Shield, Off."
162:06:40 Worden: Understand. At 163:40, you want the Image Motion, Increase to Increase/On. Do you want that - How many steps past barber pole do you want it?
162:06:59 Henize: Okay, Al. I - I missed the beat there. The one at 163:10 was "talkback barber pole plus 4 steps" at that time. And at 63:40, take it to "talkback barber pole" and leave it there.
162:07:34 Henize: Did that come through okay?
162:07:36 Worden: Okay; understand. The one at 163:10 is "Image Motion, Increase to barber pole plus 4, and then On". And then at 163:40 is "Increase to barber pole On", and "Gamma-ray Gain Step, Shield, On."
162:07:51 Henize: Roger. 163:40, that was Shield, Off; O-F-F. and at 163:50, the Gamma-ray Gain Step will go Shield, On; Shield O-N.
162:08:02 Worden: Okay. Understand 163:40, Shield is Off; and 163:50, the Shield goes On.
162:08:08 Henize: Roger. And that's the end of the Mapping Camera and the Flight Plan update.
162:08:16 Worden: Roger.
162:08:18 Henize: The computer is yours, Al. And I have [a] consumables update, if you would like it.
162:08:59 Worden: Understand. RCS total is 60. That's with quads: 60, 60, 59, 61; H2 tanks: 65, 64, 46; and O2 tanks: 71, 74, 58.
162:09:12 Henize: That's correct.
162:09:18 Worden: And where do we stand on the RCS budget, Karl. Do you know?
162:09:34 Henize: Stand by on that, Al. We'll give you a good report in a few minutes.
162:10:41 Henize: Endeavour, this is Houston. On your RCS fuel, you are running roughly 6 percent below Flight Plan values, and you're still running roughly 15 percent above the red line. Quad Charlie is the lowest - the most critical quad. But, there's no big deal at the present time in any of them. Quad Charlie, incidentally, is 10 percent above the red.
162:11:10 Worden: Okay, Karl.
162:11:11 Henize: Quad Charlie, incidentally, is 10 percent above the red line.
162:11:18 Worden: Okay. Sounds fine.
162:13:51 Henize: Endeavour, this is Houston. The latest information from Hadley Rille is that the crew is awake and about one hour from egress time. This EVA number 3 has been shortened in length somewhat to about 4½ hours in order to get our time line back on time for the nominal ascent. You can expect that you'll have some company later this afternoon.
162:14:33 Worden: Very good, Karl. And, let's see, I guess I can give you a crew status report if you want it.
162:14:40 Henize: Fire away.
162:14:42 Worden: Okay. I've got 7½ hours of sleep in one period. No medication. The PRD [Passive Radiation Dosimeter] is 23164.
162:14:54 Henize: We copy, Al.
162:18:35 Worden: Houston, Endeavour. If you're copying the DSKY, the gyro torquing angles are up [on it].
162:19:26 Henize: Endeavour, this is Houston. [A] couple of quick questions. First of all, the Surgeons see something of a difference in your heart rate between the two nights sleep, and just out of medical curiosity, they'd like to have your subjective evaluation. Did you sleep better last night than the night before, or vice versa?
162:19:49 Worden: Gee, I guess subjectively, I slept pretty well both nights.
162:19:54 Henize: Just about equal in other words? Okay, and...
162:20:00 Worden: Yes, I think so, or maybe I slept a little better last night.
162:20:03 Unidentified speaker in Houston: Better last night?
162:20:04 Henize: Glad to hear that. You're con - confounding their theories.
162:20:xx Worden: On... [Long pause.]
162:20:34 Henize: Al, we'd like to have you verify tape motion at LOS; and if it isn't, start the tape running for us.
162:20:44 Worden: Roger.
162:20:46 Henize: And, on this P30 business; I see something of a - a long comment they made to you last night. Is everything on that clear?
162:21:03 Worden: Roger, Karl. I think so. I - I guess for the story there is we'll stay away from using the pocket P30 as much as possible, and when we do use it, especially when we're in deadband, we won't let it run more than 30 minutes.
162:21:21 Henize: Okay. Everybody down here thinks that's a - a great philosophy. Good.
162:21:47 Worden: And, Houston; Endeavour. There were a couple of questions on the Flight Plan. I guess I'm wondering what we're going to do about the Mass Spec[trometer] today. We've got some things in here. Of course, we didn't use it last night, so there are, I guess, a few steps that you're to delete.
162:22:02 Henize: Righto. We don't intend to use the Mass Spec. today so you can delete these particular steps about retracting, or about extending the boom, et cetera. We just are not - That was it. Delete any action on the Mass Spec.
162:22:16 Worden: Okay. Okay Karl. Understand.
162:23:45 Henize: Endeavour, this is Houston. As you go around the corner, all your systems look to be in good shape.
162:23:53 Worden: Roger, Houston. See you at the other side.
This is Apollo Control at 162 hours, 41 minutes Ground Elapsed Time. The crew aboard Falcon presently donning their Portable Life Support System and pressure suits in preparation for the third and final extravehicular activity period of the mission, which will last about 4 to 5 hours depending on various circumstances. Meanwhile Al Worden was waked up during this last front-side pass, revolution 43. He was waked up at 161:59 Ground Elapsed Time with a little bit of Tiajuana Brass music being piped on the second of the two air/ground circuits. Unofficial estimates on the poundage or weight of samples collected during the two completed EVAs run as follows; in Sample Return Container number 1 - we'll use our EVA-1 numbers - Sample Return Container number 1, 36 pounds [16.3 kg]; bag number 4, 15 pounds [6.8 kg]; contingency sample, 2.7 pounds [1.2 kg]; for a total of 53.7 [pounds, 24.4 kg]. Second EVA; Sample Return Container number 2, 40 pounds [18.1 kg]; bag number 3, 30 pounds [13.6 kg]; and bag number 6, 33 pounds [15.0 kg] for a total EVA-2 of 103 pounds [46.7 kg] of samples. The two EVA's combined make up an estimated 156.7 pounds [71.1 kg]. We're looking at a depressurization time now, tentatively at 163:14, in that ball park, Ground Elapsed Time, depending on the length of time it takes to prepare for depressurization and egress. The air to ground circuit with Falcon is up and live and at 162 hours, 43 minutes Ground Elapsed Time; this is Apollo Control.

163:14:01 Henize: Endeavour, we'd like to have Narrow Beam on the High Gain [Antenna].
163:14:16 Worden: Okay, Houston. Got it.
163:14:23 Henize: Very good, Al. You're coming through loud and clear. What's new up there?
163:14:30 Worden: Oh, I've just had a very nice breakfast and getting ready for today's activities.
163:14:36 Henize: Excellent. [Long pause.]
163:14:58 Henize: Our major business on this rev is to get squared away for [the] plane change [burn] and as soon as we have good comm, I want to review with you the changes we need in your SPS burn cue card.
163:17:04 Henize: Endeavour, this is Houston. I guess we can go ahead with the plane change data anytime you're ready to copy.
163:17:14 Worden: Okay, Karl. Stand by one.
163:17:16 Henize: Let's start out with the cue - with the cue card, if that's okay with you. [Long pause.]
163:17:54 Worden: Okay, Karl. Go ahead.
163:17:56 Henize: Okey-doke. As you know, this burn is going to be [a] fairly normal burn on bank B only. The only really special thing to remember is to close that SPS Pilot Valve Main B [circuit breaker] at 2 minutes before the burn. To make sure that we've got all the verifications and everything else straight though, let's go back into the cue card and do some verifying right after you cycle the cryo fans and before you go into your Delta-V check. And at that point, we've got, first of all, EMS Function off. Verify that before you put in the EMS breakers. Second is the circuit breakers, EMS Main A and B, both of them, closed. Third step there is to verify that the circuit breakers, Group 5, both of them are closed. And the fourth step there is to verify at this point that both of your SPS Pilot Valve circuit breakers are open. The only other change to the front side of your cue card is the trivial point down below when you're checking your Stabilization Control circuit breakers on panel 8, that there's only 10 of them closed at this time, instead of 12.
163:19:34 Henize: Right. That's the Stabilization Control...
163:19:38 Worden: Roger, Karl...
163:19:39 Henize: ...and SPS breakers.
163:19:40 Worden: ...I understand. Yes. The SPS burn is going to be a nominal bank B burn - bank B only burn. But to get set up for it, we want to check - after cycle cryo fans, check that EMS is off, get the two EMS circuit breakers in, check that the Group 5 circuit breakers are closed, and check that the SPS Pilot Valves both are open at that time. And then down where it says 'CB Stability Control, panel 8, and SPS 10 or 12', we'll make that a 10.

163:20:11 Henize: Roger. And then over there on the back of the card... Would you give us High Gain, Auto, right now, Al?
163:20:26 Worden: Okay. [Pause.]
163:20:33 Henize: And on the back side of the card at - at minus 2 minutes, we have - the Delta-V - just above the Delta-V Thrust, we want to put in the circuit breaker, SPS Pilot Valve Main B, closed, at that point, followed immediately by your Delta-V Thrust switch, which in this case is your B switch, not your A switch. Cross out the "A." Down below...
163:21:02 Worden: Roger; understand.
163:21:03 Henize: Down below...
163:21:04 Worden: You want the SPS Pilot Valves, Main B, Closed, before Delta-V Thrust B switch to Normal.
163:21:10 Henize: That's affirmative. And down below at plus 3 seconds, you can cross out the Delta-V Thrust switch, Normal, there since this is a single bank burn. And - Al, we'd like to have High Gain Antenna, Wide Beam, for about 5 seconds and then, Narrow.
163:22:03 Henize: And the final point in the checklist is in the cleanup down below, preferably after circuit breaker SPS Pitch 1 and Yaw 1, open. Let's get our circuit breakers cleaned up here. Let's put in circuit breaker SPS Pilot Valve Main B, open. Also, circuit breakers EMS, both of them, open.
163:22:38 Worden: Roger; understand. In the cleanup, about where CB SPS Pitch 1 and Yaw 1 are open, we'll pull CB SPS Pilot Valve Main B, open, and CB EMS, two, open.
163:22:52 Henize: That's correct. And that - assuming that your cue card was clean to start with, that should give you a - a good cue card, not only for the plane change but also for any rescue maneuvers and also for the shaping burn.
163:23:08 Worden: Roger; understand.
163:23:14 Henize: I have - and, I have - the comments here on trimming your residuals, if you're ready to copy those.
163:23:57 Henize: Okay. The LOPC [Lunar Orbit Plane Change] residuals. First of all, trim VGY to 0, - 0.2 feet per second. Next, and this is because our quad C RCS is low and we're trying to conserve it, in - in the trimming. If you have a negative VGY, roll 90 degrees counter-clockwise and use your minus-Z thrusters. If you have a positive VGY, roll 90 degrees clockwise, and use your minus-Z thrusters. And, one final comment here is during - during the burn, we would like to keep the Oxidizer Flow Valve in the Decrease - Decrease position.
163:24:57 Worden: Understand you want the Oxidizer Flow Valve in the Decrease position.
163:25:02 Henize: Affirmative.
163:25:13 Henize: And did everything come through on the trim.
163:25:28 Worden: Roger, Karl. You - you wanted to add to - to the - trim rules that we already have established for the plane change. That if the residual is a plus VGY greater than two tenths of a foot per second, then we roll clockwise 90 degrees and use the minus-Z thrusters. Otherwise the same as printed in the Flight Plan.
163:25:55 Henize: That's affirmative, Al.
163:26:01 Worden: And also, you want the PUGS valve in decrease.
163:26:07 Henize: That's affirmative. And the next - the next bit of information I have for you is the plane change PAD.
163:26:28 Worden: Okay, go ahead.
163:26:31 Henize: Okay. Purpose, PC [Plane Change], SPS/G&N; 37202; plus 0.33, plus 1.07; 165:11:31.96; minus 0009.2, plus 0330.3, plus 0018.4; 0 roll, 0 pitch, 0 yaw; 064.4 - Say that again for HA. 0064.4, HP is plus 0053.3; 0330.9, 0:18, 0319.1; 36, 012.8, 39.2; the rest is NA. The set stars are Deneb and Vega; 189, 256, 330. Ullage, we would like two quads, B and D quads; 17 seconds, 17 seconds. And that's all.

163:28:17 Worden: Okay, understand. This is plane change 1; SPS/G&N; 37202; plus 0.33, plus 1.07; 165:11:31.96; minus 0009.2, plus 0330.3, plus 0018.4; roll, pitch, and yaw are all zeros; 0064.4, plus 0053.3; 0330.9, 0:18, 0319.1; 36, 012.8, 39.2. Vega and Deneb are set stars. And 189, 256, 330. Ullage is two jets, 17 seconds, using quads B and D.
163:29:18 Henize: That's all correct. [Long pause.]
163:29:54 Henize: Al, we'd like to verify that the Oxidizer Flow Valve was in the Decrease position at the end of the last burn and has been there since then.
163:30:08 Worden: Negative, Karl. It was in Normal at the end of the last burn, which was the circularization burn and it was - it's been in Normal since then. It's in Decrease now; I put it there after you called it out on the PAD.
163:30:21 Henize: Thank you, Al. [Long pause.]
163:31:10 Henize: Just a reminder, Al. Since I've been reading a lot of things to you, about the Pan Camera Mode, Standby; Power, On.
163:31:20 Worden: Roger. It's there now.
163:31:32 Henize: And I have a TEI-52 PAD anytime you're ready to copy.
163:31:54 Henize: TEI-52, SPS G&N; 36003; plus 0.60, plus 1.07; 180:31:51.88; plus 3030.0, minus 0893.9, minus 0231.0; 180, 088, 346; the rest is NA. We have two jets for 17 seconds with the B and D quads, Bravo and Delta quads. The Lambda at TIG is plus 177.77; and it is assumes LOPC; and ascent REFSMMAT.
163:33:14 Worden: Roger; understand. TEI-52, SPS/G&N; 36003; plus 0.60, plus 1.07; 180:31:51.88; plus 3030.0, minus 0893.9, minus 0231.0; 180, 088, 346; 2 jet, 17 seconds, using quads B and D. And Lambda TIG is plus 177.77; and the PAD assumes the plane change and asc - ascent REFSMMAT.
163:33:59 Henize: That's all correct. [Pause.]
163:34:11 Henize: Endeavour, we're ready for Pan Camera Power, Off, now.
163:34:22 Worden: Roger. Power is Off.
AS15-M-1795 - Metric Camera image of northern Mare Tranquillitatis including craters Vitruvius, Jansen and Beketov. Image taken at about 163:36. (250 megapixel version), (labelled version) - Image by NASA/ASU.
AS15-M-1805 - Metric Camera image of southern Mare Serenitatis including craters Bessel, Deseilligny and Tacquet. Image taken at about 163:39. (250 megapixel version), (labelled version) - Image by NASA/ASU.
163:41:51 Henize: Endeavour, a reminder on the Gamma-ray Gain Step. We need the Shield, Off, at this point.
163:46:37 Henize: Endeavour, this is Houston. We have one small change in our set-up for the plane change burn, and that is that we would like to leave the Oxidaze - Oxidizer Utilization Valve [means Oxidizer Flow Valve, on panel 3 of the Main Display Console and part of the Propellant Utilization Gauging System (PUGS)] on - in the Normal position. We'd like it Normal instead of Decrease as we previously told you.
163:47:06 Worden: Okay, going Normal on the PUGS Valve.
163:47:10 Henize: Roger; and the boys on the surface have the TV tuned up for us now and we're getting some lovely landscape pictures - Hadley Delta, et cetera. Those hills there are just beautiful, round, bare hills, a lot like the ones you see around San Francisco. It's a beautiful sight. They're just about loading up the Rover and getting ready to head off toward the South Com[plex] - first of all, to the rille for a quick visit and then off to the South Complex.
163:47:44 Worden: Roger, Karl; understand. Did you say they are going to cut it a little bit short today?
163:47:49 Henize: Right. They're going to cut it between one and two hours short because they got in - they wanted to get their normal sleep today; and, I guess they won't do quite so much exploration in between, but they still expect to get to the South Complex. Pardon me, that's the North Complex.
163:59:06 Henize: Endeavour, this is Houston. It's time to turn off the Mapping Camera.
164:02:05 Henize: Endeavour, this is Houston. If you'll go P00 now, you'll have a shorter maneuver down in your maneuver to the P52 attitude. And, if you'll give us Accept, we'll send up state vector and other burn information.
164:02:22 Worden: Okay, Karl. You've got it; P00 and Accept.
164:07:38 Henize: Al, the computer is yours; you've got a state vector, a target, and a REFSMMAT.
164:07:47 Worden: Okay, Karl; thank you. [Pause.]
164:07:58 Worden: And, Houston; Endeavour. I've got the SIM bay powered down now, and turning back all the jets - turning on all the jets.
164:08:07 Henize: Roger, Al; we understand.
164:09:15 Henize: Endeavour, this is Houston. You can expect us to give you a No - Go/No Go for LOI [means LOPC or lunar orbit plane change] before LOS. No, that's - that's right; that's a Go/No Go for plane change - pardon me, I'm a little bit behind time here - before LOS, and since your burn is so close to AOS, we'd like to give you a procedure here, so that we can lock up without your having to go over there to throw - to throw any switches. Can you copy it now?
164:09:51 Worden: Roger, Karl; go ahead.
164:09:55 Henize: Okay. After LOS, we'd like to have you put the High Gain [Antenna] Track to Manual, and dial in Pitch, minus 10; Yaw, 251. When the high gain angle - when the High Gain Antenna [angle] meters read Pitch, minus 10 and Yaw, 251, then go to Track and Reacq with Narrow Beam. Then, if your Squelch is Off, your High Gain Antenna acquisition will be indicated at AOS by a loss of noise.
164:10:43 Worden: Okay. Understand you want me to position Pitch, minus 10; Yaw pl - Yaw to 251; go Reacq, Narrow, and make sure the Squelch is Off.
164:10:52 Henize: That's affirmative.
164:12:31 Henize: Endeavour, this is Houston. You're Go for plane change 1.
164:21:18 Henize: Endeavour, this is Houston. We're 2 minutes from LOS, and all of your systems look to be in excellent shape.
164:21:28 Worden: Roger. Thank you, Karl.
165:09:45 Worden: Okay, Houston. I've got 1 minute and 45 seconds until the burn.
165:09:50 Henize: Roger, Endeavour. Houston reads you loud and clear, and we're standing by.
165:11:06 Worden: Average g.
165:11:09 Henize: Roger. [Pause.]
165:11:18 Worden: Ullage. [Long pause.]
165:11:41 Worden: Thrust on. [Long pause.]
165:11:54 Worden: Thrust off.
165:13:00 Worden: Houston, Endeavour. If you're copying the DSKY, you'll see residual as .2, .2, and .3, so no trim.
165:13:09 Henize: We copy and concur, Al, and it looks like a beautiful burn.
165:13:17 Worden: Yes, sir. It certainly does.
165:23:02 Henize: Al, if you'll give us Accept, we'll send up a lift-off REFSMMAT and a RLS update.
165:23:12 Worden: Okay, Karl. And if you're ready, I'll give you the rest of the burn status report. It's just the EMF and things like that.
165:23:19 Henize: Go ahead.
165:23:23 Worden: Okay. TIG was on time, and looked to me like the burn time was 18 seconds; Delta-VC was minus 10.6 [fps, 3.2 m/s]; fuel is now 26.4 [percent]; oxidizer is 26.2 [percent]; and Increase-Decrease [i.e. PUGS manipulation] is Decrease 25.
165:23:50 Henize: Thank you. We copy. [Long pause.]
165:24:19 Henize: And, Al, in case of confusion on that Mass Spec[trometer], we do want the experiment switch on Standby.
165:24:28 Worden: Oh, okay, Karl. Yes, there must have been some confusion because I had scratched that off my Flight Plan. Okay, going Standby. [Long pause.]
165:25:17 Henize: Endeavour, Houston. The latest bulletin from Hadley Rille tells us that the crew, after spending an unusual amount of time at the LM trying to get back the core drill, with which they were only partially successful, are now moving across the lunar surface and they're currently at Hadley Rille giving us some beautiful views of the rille.
165:25:47 Worden: Very good. How is the TV from there, Karl?
165:25:50 Henize: Our TV down here is just beautiful.
165:25:57 Worden: Good. Save a copy for me.
165:26:00 Henize: We sure will, Al.
165:26:06 Henize: Hey, Al. Vance says "Do you want us to put it on your EMF."
165:26:10 Worden: Tell Vance he's got the wrong EMF, I'm afraid. Sure would like it, though.
165:26:21 Henize: Righto.
165:26:25 Worden: And you tell Vance I got cartoons on right now.
165:26:28 Henize: Say again.
165:26:33 Worden: Just tell Vance I got cartoons on. He'll know.
165:26:41 Henize: Okay, Al. [Long pause.]
165:26:59 Henize: Al, we'd like to have you stay in Accept, but give us a Verb 33, Enter.
165:29:13 Henize: Endeavour, this is Houston. We'd like to have the Gamma-ray Gain Step up three times, please.
165:29:26 Worden: Roger, Karl. Gain Step up three times.
165:29:29 Henize: Affirmative. [Long pause.]
165:30:00 Henize: Al, you can go to Block now. We've had some conflict in commands in that update to you and you got your LR - RLS update, but you didn't get the new REFSMMAT.
165:30:16 Worden: Okay, Karl; understand.
165:31:22 Henize: Endeavour, this is Houston. Will you please give us Accept?
165:31:30 Worden: Okay. You've got Accept.
165:33:16 Henize: Al, give us Verb 33, Enter. And that should complete your REFSMMAT...
165:34:15 Henize: Endev - Endeavour, we would like High Gain [Antenna], Auto.
165:34:24 Worden: Auto.
165:34:28 Henize: Thank you.
165:41:02 Henize: Al, the medics told me that they can see that you are exercising per the Flight Plan. Would you like to know what peak value you get? Peak value on heart rate, that is.
165:41:15 Worden: Yeah. I'd be interested in that, Karl.
165:41:16 Henize: Yes. Let's see how high you can - you can...
165:41:17 Worden: Yes.
165:41:18 Henize: ...work her up. It'd be good to really churn her up for a while. [Long pause.]
165:41:52 Henize: Okay, they got you at about 100 beats per minute for a moment.
165:42:00 Worden: Very good. [Long pause.]
165:42:25 Henize: We record 116. [Long pause.]
165:42:47 Henize: You made 120. Man, you must be burning that thing up. [Long pause.]
165:43:26 Henize: Got you at 126.
165:46:22 Henize: They say that looked like a real good stretch of exercise there, Al. Should stand in good stead a couple of days from now.
165:46:32 Worden: Roger. I sure hope so, Karl; been keeping it up just for that reason.
165:46:35 Henize: Very good.
165:46:40 Worden: And I think it makes a difference in - in your whole outlook and - the - restful way that you can do this flight, too. A little exercise and I get a good night's sleep also.
165:46:54 Henize: Yes, you're probably right.
165:55:57 Henize: Al, I have a REFSMMAT zero time for you when you have time to copy.
165:56:10 Worden: Okay, Karl. Go ahead.
165:56:11 Henize: 171:37:18.89.
165:56:26 Worden: Understand 171:37:18.89.
165:56:32 Henize: That's affirmative.
166:08:31 Henize: Al, we've got your angles and you can torque them.
166:08:39 Worden: Okay, Karl. Torquing on the minute.
166:17:48 Henize: Endeavour, this is Houston. All of your systems are Go as you go around the corner, and I hope to have a science update for you on the next rev. In the meantime, I can report that the X-ray data is beginning to show very clear patterns from highlands to mare region. It looks as though we are going to - we - we are high in magnesium in the mare and high in aluminum in the highlands, which tends to confirm the anorthosite theory for the highlands. It gets rather exciting when the data starts adding up like that. And the Laser Altimeter has shown us that the back side of the Moon is indeed further from the center of the Moon than the front side. This had been a theory previously, and now you seem to have proved it with good solid data. Lots of things are beginning to fall into place, and - What a mission, that's all we can say.
166:18:56 Worden: Sounds pretty good so far, Karl. And I'm getting the SIM bay ready to have another shot of that.
166:19:09 Henize: Okay; we've been watching your maneuvering there. Have a good go at it.
166:19:16 Worden: Okay, Karl. [Pause.]
166:19:26 Henize: And the Rover boys at Hadley Rille have just had a tremendous session picking up all sorts of useful samples. The TV has been beautiful, the - All sorts of layering shows - in the - in the edge - in - in the - in the rille walls, and it's just very exciting.
166:20:05 Worden: It sounds great.
167:13:59 Henize: Endeavour, this is Houston. How do you read? [No answer.]
167:14:36 Henize: Endeavour, this is Houston. How do you read? [No answer.]
167:15:19 Henize: Endeavour, this is Houston. How do you read?
167:15:28 Worden: Hello, Houston; Endeavour. Loud and clear.
167:15:31 Henize: Roger. Hear you likewise, loud and clear.
167:16:51 Henize: Endeavour, we'd like High Gain [Antenna], Auto.
167:17:00 Worden: Okay. It's in Auto.
167:18:02 Henize: Endeavour, we need Wide Beam for 5 seconds and then Narrow.
167:21:06 Henize: Endeavour, would you confirm that [the] X-ray [Spectrometer] is On, please. [Long pause.]
167:21:23 Worden: Endeavour, negative. It's - it's Off right now, Karl.
167:21:28 Henize: Roger. We'd like to have it On, please. [Pause.]
167:21:40 Worden: Roger. Going On. And sorry about that, Karl. I switched it one position thinking I had it On, but it was really Off.
167:21:50 Henize: Righto. [Long pause.]
167:22:15 Henize: Al, another bulletin from Hadley Rille. The crew is back at the LM and starting their closeout. Just a few minutes ago, I saw them perform the philatelic wonder of the century.
167:22:34 Worden: So, it's all out now, huh?
167:22:36 Henize: Roger. [Long pause.]
167:23:23 Henize: And, Al, you'll be fascinated to know that Galileo's theory of gravitation has been confirmed. Dave just dropped a hammer and a feather and they hit the ground simultaneously.
167:23:38 Worden: Did you ask him what kind of a feather it was?
167:23:42 Henize: A falcon feather; yes, indeed.
167:23:46 Worden: How about that.
167:24:55 Henize: Al, we're up to the time to turn Pan Camera mode, Standby and Power, On.
167:25:03 Worden: Okay, Karl. [Long pause.]
167:25:19 Henize: Hey, we got a few special words also on water dumps - I guess you got one coming up in about 3 hours. They're anxious, in the future, that we don't run the waste water below 10 percent, because of possible malfunctions of the waste inlet valve, causing the suit exchanger to have oxygen breakthrough. So they'd appreciate your keeping a close eye on the - on waste dumps and - waste tank water quantity.
167:25:53 Worden: Okay, Karl. Will do.
167:28:48 Henize: Endeavour, Pan Camera Power, Off, now, please.
167:28:48 Worden: Power is coming Off. [Long pause.]
167:29:57 Henize: Al, while you're eating up there, we've got the morning news. Are you in a situation to listen?
167:30:07 Worden: Okay; yeah, Karl. Glad to hear it.
167:30:10 Henize: Okay. It looks like we've avoided a steel strike down here. The steel workers and management agreed to a one-dollar per hour pay increase last night, boosting the straight time rate to 4.45 [dollars] per hour. Maybe we should take up that trade, huh?
167:30:29 Worden: Sure sounds like it.
167:30:31 Henize: The mercury dipped to 68 degrees yesterday, a record low for the first of August in Houston; we've had some real pleasant weather here. Too bad that either you or I haven't been - had a chance to get outside to enjoy it, huh?
167:30:48 Worden: Yeah, wait 'til next week, and we'll take a vacation.
167:30:51 Henize: You said it. Representative Edith Green, Democrat of Oregon, said, "Students and parents have been misled into thinking that a college degree is the only road to success." She advocated more vocational and technical training. On the sport scene, Arnold Palmer and Jack Nicklaus combined their talents to score an easy 6-stroke victory in the National PGA Championship at Ligonier, Pa. They were 27 under par into 72 holes. The Astros smothered Montreal 8 to 1, but are still in the second division, 11 and a half games behind San Francisco. And here is a flash hot off the wire. It's only - it's only 200 years old, but very apropos of the leak that you sprang a couple of nights ago and also the big leak in the LM a couple of days ago. And the dispatch is as follows: The Endeavour, the original Endeavour, sprang a leak off the Great Barrier Reef at 11:00 p.m. on 11 June - on 11 June 1770. It was necessary for them to dump 40 tons of consumables to prevent sinking; then they sailed on with 40 feet of water in the hold. And this information comes to you courtesy of Honeysuckle Tracking Station in Australia.
167:32:24 Worden: Hey, that's very nice of Honeysuckle to tell us that. And I guess you ought to know that when we sprang a leak the other night, we didn't notice that any water had escaped. But when I made the plane change burn today, I found it, and it was sitting right in the middle of the after - of the heat shield.
167:32:43 Henize: [Laughter.] Very good. How much water was there? Can you estimate that?
167:32:49 Worden: Had a great big puddle of water.
167:32:51 Henize: A pint?
167:32:53 Worden: Oh, I'd estimate maybe a pint. Yeah.
167:32:56 Henize: Okey-doke.
167:35:30 Henize: Al, here's a little more of an update on the operation of the SIM bay experiments. The Gamma-ray, X-ray, and Alpha Particle Spectrometers are continuing to collect good scientific data. I already told you about the - the X-ray data showing regional differences very clearly. I went downstairs and looked at it myself, and it really is almost on a kilometer by kilometer basis. You can see, when you go from a highland in - into a mare; very interesting. The Laser Altimeter, as I already told you, has shown a lot of interesting things about the altitudes on the Moon. But - I'm not sure whether you know it or not - but it's essentially belly-up [i.e. dead, or not working] at the present time. We don't have much hope for it in the future. But the data that we did get out of it was very interesting and very good. And I guess that's about all I can say at the moment.
167:36:36 Worden: Roger, Karl. Thank you. That all sounds very interesting.
167:36:43 Henize: I'm not sure I told you previously...
167:36:45 Worden: And, Karl, you say - that the Laser Altimeter is just about gone now, huh?
167:36:55 Henize: Yeah. I think most people have admitted that it's not - it's giving us useless data. It has given us useless data on the last couple of attempts to use it, and we have very little hope for it now.
167:37:19 Henize: Incidentally, the Pan Camera is deteriorat - deteriorating to some extent. That V over H problem is getting - getting worse, not - it's - it's not completely bad yet, but we're getting a lower percentage of good frames, maybe 60 or 70 percent now.
167:37:51 Henize: And in connection with this deterioration of the Pan Camera, there is some feeling that as time goes by, it's getting poorer and poorer and that maybe we should occasionally pulse it on the self-test cycle to take just a - five frames on - on interesting regions as we go along in order to get the film used up before it really deteriorates to a greater degree. I guess we're asking for your opinion on that. Do you have any feeling about that?
167:38:24 Worden: No, but it sounds like a good idea. It seems to me like, good or bad, it'd be a shame to leave some unused film in the camera.
167:38:33 Henize: Roger. Well, we'll hang loose on that, and I think - I think really we ought to get a better evaluation down here as to how we - how to really use up that remaining film. People are thinking about it now.
167:38:45 Worden: Right. I agree.
167:39:59 Henize: Al, when I talked about pulsing the self test there, I - I didn't completely have the picture clear in my own mind. If the V over H sensor is giving us problems, this is one way to get around it, because, if we take our five frames in self test, we're essentially cutting the V over H sensor out of the circuit and taking a - a nominal [degree of] image motion compensation there, which would be better for us. So it's possible that, when we wind up using that film, that we'll have somebody sitting down in the lower equipment bay - probably after you're all three together again - pulsing that switch every 30 seconds.
167:40:41 Worden: Roger, Karl; understand. It sounds fine.
167:54:06 Henize: Al, we're ready to have Gamma-ray Gain Step back to center [Shield, On].
167:54:15 Worden: Okay; Going Shield, On. [Long pause.]
167:55:00 Henize: And it looks like you're going to have your fun this rev by having a good look at Aristarchus, huh?
167:55:10 Worden: Yeah, that's right, Karl. I've looked at Aristarchus a couple of times already in Earthshine, and I'll tell you even in Earthshine, that thing is spectacular. I can see Schröter's Valley; it shows up very white, and the crater Aristarchus with the rays extending to the west are all - they're all very, very visible.
167:55:29 Henize: Roger. [Long pause.]
167:55:43 Worden: And I'm just at the terminator now.
167:55:49 Henize: We copy.
168:04:11 Henize: We see you moving over to the antisolar point to take some gegenschein photos. It's about time we solved that problem, Al. Take some good ones. That Nikon camera ought to do a good job for us.
168:04:26 Worden: Well, we are all set up here, Karl; and, if the Nikon will do it, we'll get them.
168:04:33 Henize: Very good. [Pause.]
168:04:43 Henize: Did you see the seven rilles of Aristarchus, Al?
168:04:52 Worden: Certainly did. [Garble.] Not much to relate at this time as far as Aristarchus - or descriptions - visual observations are concerned in Earthshine. As a matter of fact, it was so close to the terminator that I wasn't really dark-adapted enough to see much except the very light colored crater Aristarchus and its ejecta pattern and a very light-colored Schröter's Valley and - which kind of surprised me. Schröter's Valley has about the same lightness as the interior of Aristarchus itself.
168:17:47 Henize: Okay, Al; as you go around the corner, all of your systems are looking in good shape. Have fun with the gegenschein photos.
168:17:57 Worden: Okay, Karl; hope so, and see you around the other side.
168:18:01 Henize: Righto.
This is Apollo Control at 168 hours, 24 minutes Ground Elapsed Time after a third EVA at 4 hours and 50 minutes and 9 seconds from depress to repress. They started depressurization of the Lunar Module at 163:17:50 Ground Elapsed Time. The crew loaded equipment aboard the Lunar Roving Vehicle at 164:04 at which time they began the trip out to the ALSEP area. And the abbreviated timeline for the third extravehicular activity included recovering the core tube which had been driven yesterday and partially loosened. That had to be recovered from the ALSEP area. From then, they drove over to station 9 on the edge of Hadley Rille and northward from there to station 10 and both places, the crew collected samples, more core samples as well as bags of rocks and fines and it was desired to get the crew back to the LM at about 167 hours which was followed fairly closely. They returned at - to the LM actually at 166:47 Ground Elapsed Time. At station 9 on the edge of the Rille, the - Scott tripped on a rock that he was unable to see because of the restrictions of his helmet visor but he recovered with some assistance from Irwin. They collected a double core sample at this station. Made several stereo photographs. And upon returning to the Lunar Module, they were successful in partially separating the balky drill stem core. Dave Scott cancelled a new stamp which is being issued today. This stamp was on a blank envelope addressed to no one and will go to the Post Office Department. Scott also recreated or paraphased, I should say, Mr. Galileo's experiment of several centuries ago by dropping a hammer and a feather to show that gravity was not dependent upon the weight of an object. They parked the Lunar Roving Vehicle about a 100 yards east of the Lunar Module on a slight rise to view the ascent into lunar orbit with the television camera which was also acting up somewhat today with slipping clutches. Finally returned to the Lunar Module and completed repressurization at the end of the third EVA. Amp-hours remaining on the two LRV batteries are 83 and 90 respectively. The Command Service Module made a plane change at 165:11 which changes the plane to coincide with the plane of the Lunar Module when it ascends into lunar orbit again. And the plans are now is to command the television camera back on to hopefully record at least the ignition and staging phases of Lunar Module ascent. Handover going on in the Control Center from the Gold team to the Maroon team. We have, at this time, no estimate of when the change of shift briefing will be in the Houston News Center. And at 168 hours, 30 minutes Ground Elapsed Time, this is Apollo Control.

169:06:26 Mitchell: Yeah, it's morning down here, Al. Al, we've got a couple of changes for you. We're going to delete the P22 because the LM crew needs a little extra time, and substitute a P24 from the Command Module for it. If you've already got your camera on the sextant, sorry about that. If not, delete it.
169:06:49 Worden: Okay. I've already got it on, but that's no problem.
169:06:53 Mitchell: Okay. We'll give you a P24 landmac - landmark track PAD whenever you're ready.
169:07:05 Worden: Okay, go ahead.
169:07:07 Mitchell: Okay. Your target's the LM. T-1, 169:34:08; T-2, 38:15; TCA, 40:38; T-3, 41:06; south 3 nautical miles; and your attitude will have changed a little, Al. We're using roll, pitch and yaw of 000 350/231 and 000. Noun 89, latitude 26.107; longitude over 2, plus 01.828; altitude, minus 013.26; and, at 169:25 in your Flight Plan, change the R2 of Noun 78 to minus 080.00.
169:08:50 Mitchell: Al, I gave you a wrong time [for the R2 change]...
169:08:51 Worden: Roger, Ed; copy...
169:08:55 Mitchell: 169:15 is the time where that should be. I don't see it there.
169:09:04 Worden: Okay, Ed. I have - I have that one in the Flight Plan now; at 169:15, R2 is minus 068.00.
169:09:13 Mitchell: That's affirm; and we're substituting minus 080.00.
169:09:26 Worden: Understand; substitute for that minus 080.00.
169:09:30 Mitchell: That's affirm, Al.
169:09:31 Worden: Okay; here goes the landmark tracking PAD. P24 on the LM, T-1, 169:34:08; T-2 is 38:15, 40:38, 41:06; that's 3 miles south; roll, pitch, and yaw are 000, 350/231, 000. Noun 89's are plus 26.107, plus 01.828, minus 013.26; and I've changed R2 of the DAP load.
169:10:12 Mitchell: Okay, Al; and we will need marks on them of course.
169:10:18 Worden: Roger.
169:10:23 Mitchell: Be back with you in a little while.
169:10:27 Worden: Oh, okay.
169:20:33 Mitchell: Endeavour, Houston.
169:20:38 Worden: Houston, Endeavour; go ahead.
169:20:40 Mitchell: Al, it seems like we had a - error on that last PAD I read you. The altitude should be minus 001.33. Understand?
169:20:54 Worden: Understand the altitude should be minus 001.33.
169:20:57 Mitchell: That's affirm. Sorry about that.
169:26:28 Mitchell: Endeavour, Houston. Omni Charlie, please.
169:26:34 Worden: Omni Charlie.
169:29:05 Mitchell: Endeavour, Houston. On your High Gain [Antenna], go Wide and Manual, please.
169:29:17 Worden: Roger. Wide and Narrow - Wide and Manual.
169:29:19 Mitchell: Thank you, Al.
169:29:25 Worden: Okay. Any angles you want me to put in?
169:30:42 Mitchell: Endeavour and Falcon, Houston. We're going to delete the VHF check at this pass, just to give you a little more time.
169:31:00 Worden: Roger. Endeavour's got the VHF set up anyway.
169:31:04 Mitchell: That's fine. We just won't - bother the LM with it.
169:31:11 Worden: Okay. You might tell them though, I've got my - if you want to check out the rendezvous radar, I've got the transponder on.
169:31:19 Mitchell: Al, you're in the mud. You'll have to try me on that one again.
169:31:25 Worden: Okay. Just wanted to let you know that I've also got the rendezvous transponder on.
169:31:30 Mitchell: Okey-doke. Thank you Al.
169:33:14 Mitchell: Endeavour, Houston. One minute to T-1.
169:33:20 Worden: Roger. Thank you.
169:37:45 Mitchell: 30 seconds to T-2. [Pause.]
169:38:03 Mitchell: 10 seconds to T-2, Endeavour.
169:38:10 Worden: Roger.
169:41:37 Worden: Okay, Houston; Endeavour. Through with tracking, but I'm not sure they're very good marks.
169:41:43 Mitchell: Okay, Al; we understand. High Sun angle may have made it difficult.
169:41:56 Worden: Yeah, I seemed to have a lot of interference sextant, from the landmark, by the sight - part of the optics.
169:42:03 Mitchell: Understand, Al. [Long pause.]
169:42:16 Mitchell: Al, do you think you saw him at all?
169:42:24 Worden: Yeah. I think the first couple of marks were on him, Ed, but I couldn't hold him.
169:42:29 Mitchell: Okey-doke.
169:42:31 Worden: I kept - I kept losing him.
169:57:51 Mitchell: Endeavour, Houston. In the blind, give us the best Omni[directional antenna], please. [Long pause.]
169:58:17 Mitchell: En - Endeavour, Houston. Best Omni, please. [No answer.]
169:59:52 Mitchell: Endeavour, Houston. In the blind, best Omni, please. [No answer.]
170:00:03 Mitchell: Endeavour, Houston. Best Omni. [No answer.]
170:14:47 Mitchell: Endeavour, Houston. In the blind. How do you read? [No answer.]
170:15:02 Mitchell: Endeavour, Houston. Give us your best Omni, please. [Long pause.]
170:15:29 Mitchell: Endeavour, Houston. In the blind. I'm going to give you a lift-off time: 171:37:22.36. We'll uplink you at AOS since we have no contact. And, Endeavour; Houston. TPI, 172:29:39.00. I'll repeat, lift-off, 171:37:22.36; TPI, 172:29:39.00. CSM weight for your DAP, 35995.
This is Apollo Control at 170 hours, 17 minutes. The updated coordinates for the LM impact point are 26 degrees, 24 minutes north; 1 degree, 6 minutes east.
170:17:15 Mitchell: And, Al, if you read. Let's come around to AOS. Trying to get comm. We'll have a lot of work to do.
170:17:35 Mitchell: Endeavour, Houston. One minute to LOS.
170:17:41 Worden: Roger, Houston; Endeavour. And did you get the gyro torquing angles, Ed?
170:17:47 Mitchell: Al, we haven't had you for the last 20 minutes. Did you get my uplinks - or rather my PADs up?
170:17:57 Worden: Negative.
170:17:58 Mitchell: Okay. Let me give you one quickly. You've got 40 seconds to LOS. TIG is 171:37:22.36. TPI, 172:29:39.00. Your CSM weight 35995. I'm going to lose you in about 15 seconds. We'll get all your uplinks and the rest of the PADs at AOS.
