Public Affairs Officer: This is Apollo Control, Houston, at 194 hours, 56 [194:44] minutes Ground Elapsed Time. We're less than a minute away now from reacquiring Apollo 16 now [on] its 62 - sixty second revolution. We show a little more [than] 13 minutes away now for time of Lunar Module jettison and this will be coming up on this frontside pass, and the Command and Service Module separation is scheduled some 5 minutes later. This is at 195 hours, 15 minutes Ground Elapsed Time. It will be [a] two foot per second retrograde burn. We'll stand by and await conversation with the crew of Apollo 16. At 194 hours, 57 minutes continuing to monitor, this is Apollo Control, Houston.
[Acquisition of Signal at about 194:47.]
Public Affairs Officer: We're now receiving data from the spacecraft.
194 47 12 Hartsfield: Orion, Houston.
194 47 21 Mattingly: Hello, Houston.
194 47 2h Hartsfield: Roger. Where are you in the checklist now?
194 48 21 Duke: Houston, 16.
194 48 22 Hartsfield: Hello, 16; this is Houston. Go ahead.
194 48 29 Duke: Okay, Hank. We're closed out. The tunnel vent - the tunnel is being vented now. One question on that LM - that was a pretty big bird. You got enough RCS - I did not crossfeed. You got enough RCS?
194 48 47 Hartsfield: Stand by.
194 49 36 Hartsfield: Apollo 16, Houston. Would you verify that you left Orion in Auto and not Attitude Hold?
194 50 07 Duke: Okay. I went to Att Hold. Over.
194 50 13 Hartsfield: Roger. Copy, Att Hold.
194 50 23 Duke: Hank, we had everything scratched out there. I had so many erasures on this page that it just got by - left in Att Hold.
194 50 33 Hartsfield: Roger. Understand.
194 54 20 Mattingly: Houston, can we go ahead with the logics check?
194 54 28 Hartsfield: Roger. Proceed with the logics check, and we're trying to get a Go/No Go on the jett right now.
194 54 37 Mattingly: Okay. We're going be tight. We're still doing the integrity check,
194 54 48 Mattingly: Okay; the logics are both on.
194 54 50 Hartsfield: Go for Pyro Arm.
194 54 59 Mattingly: Say again, Hank.
194 55 00 Hartsfield: Roger. You're Go for Pyro Arm.
194 55 06 Mattingly: Okay. Okay.
194 56 23 Hartsfield: Apollo 16, Houston. We're Go for LM jett.
Public Affairs Officer: This is Apollo Control, Houston 195 hours, 9 minutes Ground Elapsed Time. Standing by now for word on LM jettison.
194 57 17 Hartsfield: Apollo 16, you have a Go for LM jett.
194 57 24 Mattingly: Roger. We have a Go for LM jett. We'll try to make it.
194 57 55 Hartsfield: 16, make sure your suit integrity checks are okay before you do it.
194 58 53 Mattingly: Okay, Houston; we're going to be about 45 or a minute late. Is that okay?
194 59 02 Hartsfield: That's okay.
194 59 54 Mattingly: LM jett complete.
194 59 57 Hartsfield: Roger. Copy. Jett complete.
195 00 43 Mattingly: Houston, the LM doesn't seem to be holding attitude.
195 00 48 Hartsfield: Roger. Understand doesn't seem to be holding attitude ?
195 00 54 Mattingly: That's affirmative. Okay. And, Hank, would you run over my RCS select procedures again? I'm not sure I got the right combination for you.
195 01 22 Hartsfield: Okay, Ken. We don't have High Bit Rate. The way you can do this is ...
195 01 29 Mattingly: What should they be, please?
195 01 33 Hartsfield: Okay. We just want the single jet authority in roll. That's the only thing we have to worry about the boom. And you're gonna have to burn out the - your Y as if you were trimming the plane-change burn, using that same roll and - roll 90 degrees to get rid of your Y.
195 02 08 Mattingly: If I go into attitude, I can get it all in - get rid of the Y anyhow, can't I?
195 02 12 Hartsfield: Say again, Ken?
195 02 19 Mattingly: If I get over to zero yaw, I can get rid of this Y. Isn't that correct.
195 02 24 Hartsfield: Stand by.
195 03 18 Hartsfield: Okay, Ken. And, of course with - you can't trim plus-Z. That's just like as if you were trimming on TEI. You're going to have to roll 90, and trim out your - your plus-Z.
195 03 31 Mattingly: Okay.
195 03 32 Hartsfield: Roger. You've got the stick.
195 03 36 Mattingly: Roger.
Public Affairs Officer: Mattingly working with his onboard computer now and Program 41, the RCS program.
195 05 31 Hartsfield: Casper, give as Omni Charlie.
195 05 49 Duke: You've got Omni Charlie.
195 05 51 Hartsfield: Roger. Thank you.
195 06 14 Hartsfield: Apollo 16, Houston. Give us your best Omni.
195 06 31 Duke: You're in Bravo.
195 06 33 Hartsfield: Roger. That sounds pretty good, Charlie.
195 06 43 Mattingly: The residuals of Noun 85 at the time we quit burning were plus 0.2, plus 0.2, and minus 0.1. I'll give you the angles. Noun 20: 270.08, plus 011.74, plus 001.94.
195 07 07 Hartsfield: Roger. Copy, Ken. And we have a boom jettison attitude for you.
195 07 56 Duke: Okay. Could you say what your boom jettison attitude is, Hank?
195 07 59 Hartsfield: Roger. 140, 357, 000; and the jett time is - We've selected as 195:35, but the time is good from 00:25 to 00:45.
195 08 19 Duke: Roger.
195 08 36 Hartsfield: And, 16; Houston. The high-gain angles for that attitude are plus 6, 345 yaw.
195 08 53 Duke: Hey, Houston; 16. Do they have control of the LM?
195 09 02 Hartsfield: Doesn't appear that we have, Charlie. That pitch angle was 357.
195 09 16 Duke: Okay, 357. 140, 357, 000 for boom jett.
195 09 21 Hartsfield: That's affirmative. And we need Manual and Wide on the High Gain for that - those angles I gave you.
195 09 41 Duke: Okay. Say again the high-gain numbers, again.
195 09 45 Hartsfield: Roger. Plus 6 for pitch, yaw 345, Manual and Wide.
195 10 15 Duke: Okay, Houston. Tell me what you think went wrong on that LM jett.
195 10 23 Hartsfield: Stand by. We're still trying to psych it out.
195 11 56 Duke: Houston, Orion didn't look like she fired any jets when we separated at all.
195 12 04 Hartsfield: Roger. Copy. No jet firing. And we didn't see any on the telemetry that we had down here, either.
195 12 37 Young: That Orion was a mighty good spacecraft. Real beautiful flying machine and a real great lunar base, too. We'll miss her.
195 13 16 Duke: When you had data there, Hank, on Orion, how did the RCS system look?
195 13 28 Hartsfield: They looked good, Charlie.
195 16 07 Hartsfield: Apollo 16, Houston. If possible, we would like to have somebody watch when you jettison the boom; see if they can see it going.
195 16 18 Mattingly: Okay.
195 16 29 Mattingly: Hank, would you give me the jettison time again, please?
195 16 34 Hartsfield: Roger. We have given you a time of 195:35 [195:23], Ken, hut anywhere between 00:25 and 00:45 is good.
195 16 48 Mattingly: Okay. That goes for 00:25 to 00:45.
195 16 57 Hartsfield: This attitude should put the CSM out in front of everything, the boom and the LM.
195 21 01 Hartsfield: Apollo 16, Houston; could you bring up the High Gain?
195 21 07 Mattingly: Okay.
195 21 33 Hartsfield: And, Apollo 16; for your information, that boom jett velocity is somewhere in the neighborhood of 7 feet per second.
195 21 44 Mattingly: Okay.
195 21 49 Hartsfield: Reacq and Narrow on the High Gain, please.
195 21 54 Mattingly: Okay.
Public Affairs Officer: Apollo Control, Houston. The loss of attitude control on Lunar Module Orion precludes the possibility of a targeted burn. A decision is still pending, whether a burn attempt should be made. Data makes it questionable as to whether or not it is possible, in fact. We're at 195 hours, 34 minutes ground elapsed time. This is Apollo Control Houston.
195 22 57 Mattingly (onboard): You should not, but if you get one, it'll come on right away.
195 23 02 Duke (onboard): Okay.
195 23 03 Mattingly (onboard): And I'll get up here and see if I can look out this side hatch, too.
195 23 07 Young (onboard): Okay.
195 23 12 Mattingly: Okay. We're about to jettison the boom.
195 23 13 Young (onboard): Okay.
194 23 14 Hartsfield: Roger.
195 23 14 Mattingly (onboard): Okay; go.
195 23 15 Duke: Okay. It's up ...
195 23 18 Mattingly (onboard): Okay.
195 23 19 Duke (onboard): ... and off. There she goes.
195 23 23 Mattingly (onboard): Boom clear.
195 23 23 Duke (onboard): Straight out. Boom's clear.
195 23 24 Mattingly (onboard): I'll see if I can see it.
195 23 25 Duke (onboard): Not a bit of roll. There she goes, Ken, this way...
195 23 28 Young (onboard): [Garble] see it.
195 23 29 Duke (onboard): ...straight out Window 5.
195 23 32 Mattingly (onboard): Hey, that is beautiful.
195 23 30 Hartsfield: Understand the boom blew clear. Is that correct?
195 23 34 Young (onboard): That's affirmative.
195 23 35 Mattingly [Young in CM transcript]: That's about as stable as you can get. That thing isn't tumbling, rolling, doing a thing.
195 23 42 Young (onboard): Let me see it. Can I see it?
195 23 43 Mattingly (onboard): Yeah. It's right straight out there. Beautiful. Here, Charlie. Charlie?
195 23 43 Hartsfield: Hey, it's great to know one thing works.
195 23 49 Duke (onboard): Yeah.
Public Affairs Officer: Apollo Control, Houston. Ken Mattingly reporting the Mass Spectrometer boom has been jettisoned. We're at 195 hours, 36 minutes [195:24] Ground Elapsed Time.
195 23 53 Young (onboard): There she goes.
195 23 56 Duke (onboard): Gee, I hadn't even thought of that [garble].
195 24 00 Mattingly (onboard): It's all set.
[End of CM transcript.]
195 24 25 Hartsfield: Apollo 16, if you can get to it, we'd like to terminate the Bat A Charge.
195 24 43 Mattingly: That's terminated, Hank.
195 24 44 Hartsfield: Roger. Thank you.
195 26 20 Hartsfield: Apollo 16, Houston. We've got a Flight up - Flight Plan update we would like to get up to you, if we could get one of you to doff a suit right quick. It would be easier to copy.
195 26 31 Mattingly: I'll just copy right now, Hank. Doffing suits is nothing easy for anybody.
195 27 28 Mattingly: Hank, can we go ahead and go to the satellite launch attitude?
195 27 34 Hartsfield: That's affirmative.
195 27 56 Mattingly: Okay, and is there any reason not to have couples on now?
195 28 10 Hartsfield: That's negative. You can go couple now, Ken.
195 28 26 Mattingly: Okay. I have.
195 28 34 Hartsfield: Okay, Ken, and the first changes we want to get to, start at Page 3 - 328.
195 28 53 Mattingly: Go ahead.
195 28 55 Hartsfield: Roger. Now, 218 hours there is now 196:10 [195:59]. And you have a constant delta ...
195 29 01 Mattingly: Yes, sir.
195 29 02 Hartsfield: ... constant delta from now on of subtracting 21 hours and 50 minutes, and this will apply through TEI.
195 29 14 Mattingly: Okay, that's a minus 21:50 through TEI, and I think I have marked all my pages with that amount already.
195 29 28 Hartsfield: All righty. Then the first change is at 196:21. Delete the "Verb 48" and the "P20" and the "Set Omni." Just delete that group of data.
195 29 53 Mattingly: Okay.
195 29 54 Hartsfield: At 196:35, add "Enable all jets, except A-1, A-2, B-1, Bravo 2, Delta 1, Delta 2."
195 30 19 Mattingly: Hank, is that the SlM jett - jett configuration?
195 30 21 Hartsfield: Negative. This gives you couple jets in all axes but roll, and we want Quad 3 providing roll control. Now this is so FDO can get good tracking for TEI, and this is being coordinated with OSC and is acceptable to the Mapping Camera pads.
195 30 40 Mattingly: Okay, why don't you - you read me a list of jets not to have on. Is that right?
195 30 48 Hartsfield: That's affirmative. Everything on, except Alfa 1 and Alfa 2 ...
195 30 53 Mattingly: Okay, now - Keep going.
195 31 02 Hartsfield: ... Bravo 1, Bravo 2, and Delta 1 and Delta 2.
195 31 14 Hartsfield: This just gives you B/D Roll, Off.
195 31 22 Mattingly: Yea, that Logic probably should go back to - No, - center. Bottom position's okay, too. That's it.
195 31 44 Hartsfield: Do you have that, Ken?
195 31 49 Mattingly: Okay, at 35 - that's 196:35, you've got enable everything except these, and the exceptions are A-l, 2, B-l, B-2, D-l, and D-2.
195 32 00 Hartsfield: That's correct. And following that, P20 Option 5 plus-X forward SIM attitude - to be there at 196:4l. Noun 79, 0.5-degree dead band. High Gain, Pitch 10, Yaw 0 for A0S acq.
195 32 43 Mattingly: Okay, Hank, does that mean that the - that the jettison attitude is going to be very close to the P20 attitude?
195 32 58 Hartsfield: Should be about a six-minute maneuver.
195 33 08 Mattingly: Well, was there any reason for not doing all that stuff earlier?
195 33 15 Hartsfield: What are you referring to, Ken?
195 33 20 Mattingly: Well, you just gave me a maneuver here to be done after I enable the engines at 00:35 and - and to be there by 00:41. And, we keep running into these things where you roll out and start the camera; and, if that's the case, I'd like to start the maneuver a little earlier. I'd like to have some padding there.
195 33 50 Hartsfield: Okays I guess I don't see any magic about - about the time when you do that. If you want to back it up, that's fine.
195 33 59 Mattingly: Okay. We'll do so. Thank you very much. But we'll be there in any event by 00:41.
195 34 06 Hartsfield: Roger. And at 00:42, and I don't see why you can't do this one early either, Mapping Camera/Laser Altimeter Cover, Open; Mapping Camera, Extend.
195 34 27 Mattingly: Okay. We'll get the Mapping Camera covers open and the Camera extended.
195 34 34 Hartsfield: At 196:47 [196:35], Laser Altimeter, On; Image Motion, On; Mapping Camera, On; T-start; Image Motion, Increase, barber pole plus 1. And your T-start is 196:49:43.
195 35 11 Mattingly: Okay. T-start is 196:49:43.
195 35 25 Mattingly: And we'll have the Laser, On, and the IMC, On, and we'll go to barber pole plus 1.
195 35 33 Hartsfield: That's affirmative. And at 196:52, orbital science visual, King. That's Victor 4. It's on charts Delta 4 and Delta 5, window 5. And note that the visual runs until 197:02.
195 36 16 Mattingly: Okay. We'll cover King on window 5 when we go by it.
195 36 23 Hartsfield: Roger. And at 196:56 [196:44]: acquire mix - MSFN, Manual, Wide, Pitch 10, Yaw 0.
195 36 45 Mattingly: Okay. We'll acquire MSFN at Pitch 10 and Yaw zero, in Manual and Wide.
195 36 50 Hartsfield: Okay, Ken, and we'll save the rest of this until the next rev. You can go ahead and start dopping [sic - "doffing"?] and getting ready for the satellite jett.
195 37 00 Mattingly: Okay. Thank you.
195 39 40 Young: Okay, Houston. Going off comm for doffing the suits.
195 39 44 Hartsfield: Roger. Copy.
195 39 59 Duke: Hank, before tomorrow, we'd like - well, right away, would - would you guys ask the suit people what we could do to get some lubrication into these wrist rings? John and mine are real tight, and we're get - finding them very difficult to lock. Over.
195 40 19 Hartsfield: Okay, Charlie. I'll do that.
Public Affairs Officer: This is Apollo Control, Houston, at 195 hours, 59 minutes Ground Elapsed Time. in the Mission Control Center, it has been completely - we have completely ruled out the possibility of any further plans for Lunar Module Orion. No further burn attempt will be made. We show 11 minutes away from Loss of Signal with Casper. We'll stand by and continue to monitor the conversations as they develop. At 196 hours Ground Elapsed Time, this is Apollo Control.
195 55 01 Mattingly: Houston, 16.
195 55 04 Hartsfield: Go ahead.
195 55 08 Mattingly: Hank, I'm looking ahead here trying to find out where we have a Pan Camera turn-on, and I don't see it. Maybe I'm missing it somewhere. Can you - I thought you said something about we're supposed to have both a Mapping Camera and a Pan Camera pass.
195 55 22 Hartsfield: Roger, Ken. We get it on it just after AOS at 197:03 [196:52]. We got some more changes for you for that Rev, and we thought we'd read them up the first part of the rev, rather than clutter you up right now.
195 55 37 Mattingly: Why don't you clutter me up right now with those things, please.
195 55 41 Hartsfield: You want them now? Okay, 197:03 -
195 55 46 Mattingly: Yes, please. Go ahead.
195 55 55 Hartsfield: Okay, 197:03 [196:52]; Image Motion, Increase; barber pole, On; Pan Camera, Standby, Stereo, Power; 197:05, configure camera for orbital science; CM5/EL...
195 56 37 Mattingly (onboard): Whose?
195 56 12 Hartsfield: ...250/CEX intervalometer. That's f/8, 1/250...
195 56 48 Duke (onboard): Huh?
195 56 50 Hartsfield: ...infinity. You'll be taking 128 frames...
195 56 55 Mattingly (onboard): I think this is where it's - where it's bad.
195 56 57 Hartsfield: ... magazine Romeo Romeo. 197:14, PC ...
195 57 02 Mattingly (onboard): [Garble] got it [garble].
195 57 10 Mattingly: Okay, what's that going to be a target of, Hank?
195 57 13 Hartsfield: Okay, we're going to pick up that long run you had that; started down at Vogel and...
195 57 23 Duke (onboard): Why don't you get a new one of those?
195 57 26 Hartsfield: ... and went up to Lassell and Alpetragius end stopped. And then you picked up at the one down at Bullialdus. Well, Bullialdus ...
195 57 23 Duke (onboard): Why don't you get a new one of those?
195 57 11 Hartsfield: ... PC - Okay, we're going to pick up that long run you had that started down at Vogel and ...
195 57 23 Duke (onboard): Why don't you get a new one of those?
195 57 26 Hartsfield: ... and went up to Lassell and Alpetragius end stopped. And then you picked up at the one down at Bullialdus. Well, Bullialdus ...
195 57 32 Duke (onboard): Hey, John.
195 57 33 Hartsfield: ... is too far south. So what we're going to do is start at Vogel, make a Jog at Alpetragius, and go all the way to the Helmet on past Gassendi. And we're about up on LOS now; I'll tell you more about that at AOS.
195 57 47 Mattingly: Okay, Hank. Thank you.
[Loss of Signal at about 195:58.]
Public Affairs Officer: This is Apollo Control, Houston at 196 hours, 11 minutes Ground Elapsed Time. We've just had Loss of Signal with Apollo 16 now on its 62nd revolution around the Moon. Meanwhile in the Mission Control Center, we're in the process of a change of shift. Pete Franks' Orange Team of flight controllers coming aboard now. The Flight Director for the shift departing, Phil Shaffer. We're at 196 hours, 11 minutes Ground Elapsed Time, and this is Apollo Control, Houston.
195 58 08 Mattingly (onboard): Okay. What were you getting ready to ask?
195 58 l0 Young (onboard): Huh?
195 58 11 Mattingly (onboard): What were you getting ready to ask?
195 58 12 Young (onboard): [Garble].
195 58 l3 Mattingly (onboard): Okay. I got to - got to launch this satellite now.
195 58 18 Duke (onboard): What time does that come on?
195 58 20 Mattingly (onboard): In three minutes. John, can you get over there? I got to launch this satellite in three minutes.
195 58 25 Young (onboard): Sure.
195 58 29 Mattingly (onboard): Okay; I'm Panel 230. Check that the Data System is On.
195 58 37 Duke (onboard): Here, I'll get it, John.
195 58 39 Young (onboard): [Garble].
195 58 42 Mattingly (onboard): Okay. On Panel 230, you got a couple more things. Make sure the - Is the Gamma Ray retracted? Is the switch down in Retract position and is the talkback gray?
195 58 58 Young (onboard): Yeah.
195 58 59 Duke (onboard): [Garble].
195 59 00 Mattingly (onboard): Okay; before I can tell if that talkback's gray, are those switches on 181 in the center Off or in the Deploy/Retract position? Put them down to Deploy/Retract.
195 59 16 Young (onboard): [Garble].
195 59 19 Mattingly (onboard): Huh?
195 59 20 Young (onboard): Gamma Ray's still gray.
195 59 21 Mattingly (onboard): Okay. Alpha/X-Ray Covers, Close, Charlie.
195 59 26 Duke (onboard): Oh, sure.
195 59 27 Young (onboard): Alpha/X-Ray ...
195 59 28 Duke (onboard): Hey, wait a minute. They're here. They are closed.
195 59 38 Mattingly (onboard): We're in attitude; we've been damping rates. Holy smokes! Where was I going to put that attitude? Okay.
195 59 55 Mattingly (onboard): Okay, on 250, we've already checked our Pyro A, Sequential A; Pyro B, Sequential B is Closed. Okay; on 181. Logic Power, two, is closed. We know that. The Logic Power switches, two of them, up to Jettison.
196 00 36 Duke (onboard): That [garble] switch?
196 00 42 Crew: [Garble].
196 01 12 Mattingly (onboard): Okay. And the circuit breakers are in? The two logic guys next to them? All right.
196 01 55 Duke (onboard): Two, 3, 4, 5 -
196 02 01 Crew: [Garble].
196 02 35 Mattingly (onboard): Okay, did you turn? Retract?
196 02 46 Young (onboard): Barber pole?
196 02 51 Young (onboard): [Garble] go gray?
196 02 54 Young (onboard): It went back to the center Off position?
196 02 58 Young (onboard): Okay, Logic Power [garble] 181 [garble] Deploy/Retract. That's done.
196 03 06 Young (onboard): Okay.
196 03 08 Young (onboard): All right.
196 03 15 Duke (onboard): I found our - I found their mistake. Their mistake. They left the - they didn't have any AC power [Garble].
196 03 35 Young (onboard): Yeah.
196 03 45 Young (onboard): [Garble].
196 03 51 Young (onboard): Okay, Charlie. It's - it's no good then.
196 03 54 Duke (onboard): Okay [garble].
[Break in transcript until Acquisition of Signal at 196:44.]
[Start of Lunar Rev 63 at 196:35.]
[Acquisition of Signal at about 196:44.]
Public Affairs Officer: This is Apollo Control at 197 hours, 10 minutes. During the change of shift briefing we reacquired Apollo 16. The Spacecraft [is] now in its 63rd revolution of the Moon. We expect this to be a relatively quiet front side pass. Among the things that we'll be reading up for the crew, will be the numbers that they will use, these will be preliminary numbers, for the Trans-Earth Injection maneuver. Which is to occur on the 65th revolution at about 200 hours, 33 minutes Ground Elapsed Time. Ken Mattingly is presently operating the cameras getting some pictures from the Command Module and also we'll have the Pan Camera operating during a portion of this front side pass. We have accumulated a small amount of taped conversation we'll replay that for you at this time and then continue to stand by live.
196 44 30 Peterson: Casper, Houston. How do you read?
196 44 45 Peterson: Casper, Houston. How do you read?
196 45 22 Peterson: Casper, how do you read Houston?
196 45 30 Mattingly: Hello there.
196 45 32 Peterson: How you doing?
196 46 28 Mattingly: Okay, looks like we got a good lock now.
196 46 32 Peterson: Okay. And, Ken, would you verify that you copied the Flight Plan changes at 197:03 and 197:05 that were given just prior to LOS.
196 46 51 Mattingly: Well, I don't know if I copied the ones that you think you gave. I copied some that said, "IMC to barber pole, and Pan Camera, Standby, Stereo, Power," and then something got started about orbital science photos, and that was all I got.
196 47 06 Peterson: Okay, the first one there that you just read back was at 197:03; and at 197:05, we have "Configure Camera for orbital science, Command Module 5/EL/250/CEX intervalometer f/8, 1/250, infinity, 128 frames, magazine Romeo Romeo."
196 48 30 Mattingly: Don, you gonna give me some words on what that target is?
196 48 35 Peterson: Stand by one. I'll get you that.
196 48 41 Mattingly: Okay, why don't you - can you give me some idea of how long it'll be? I'm - I - I don't know whether I have time to take my suit off or what.
196 48 57 Peterson: Okay, Ken, that - that target position you're going to add are Vogel, and - and that goes all the way up through the cinder cone there. Actually, you're changing over at Alpetragius - a little jog, and then on up past the cinder cone. And you were originally scheduled to look at Bullialdus, and we're going to have to delete that because your track is too far to the north now. So, we're going to bring your groundtrack from the cinder cone right on up through Helmet and Gassendi and on up to Mersenius Rille, from D-11, 12, and 13.
196 49 41 Mattingly: Okay, you want to take one continuous strip.
196 49 43 Peterson: That's affirmative.
196 49 44 Mattingly: Make one continuous strip from Vogel to Alpetragius to the cinder cone to the Helmet to Gassendi to the Mersenius Rille.
196 49 54 Peterson: That's affirmative; except there will be that little jog at Alpetragius over to - to the right there and then on up through cinder cone and straight on up through Helmet, then Gassendi and on up to the rille.
196 50 08 Mattingly: Yeah, I understand that. I'm going to have to have some help on the f-stops, and I guess I'd rather have you call them out to me rather than have me try to write them down and jot them on a map and all that jazz.
196 50 20 Peterson: Okay; we'll do that.
196 50 25 Mattingly: Okay; thank you. And can you give me a time for passage of Vogel?
196 50 30 Peterson: Okay, hang on a minute.
196 50 45 Peterson: Okay, it looks like 197:29 is for Vogel. And it'll be a continuous pass from that point on.
196 50 59 Mattingly: Okay; thank you.
196 51 07 Peterson: Okay, and I have a couple of other updates at 197:14 and 15.
196 51 18 Mattingly: Go ahead.
196 51 19 Peterson: Okay, at 197:14 [197:12], it's Pan Camera, Operate; T-start 197:14:18.
196 51 33 Mattingly: Okay, that's 197:14:18 [197:12:28] for the Pan Camera to be running. We'll get it.
196 51 37 Peterson: Roger. And right now, you're up to that point where you should go Image Motion, Increase, and Pan Camera, Standby, and all that stuff at 197:03 [196:52].
196 51 42 Mattingly: Okay.
196 51 50 Peterson: Okay; and at 197:15 [197:03], we want Image Motion, Increase.
196 51 57 Mattingly: Stand by, please.
196 52 02 Peterson: Okay. Standing by.
196 52 37 Mattingly: Okay, Don. Go ahead.
196 52 38 Peterson: Okay, at 197:15 [197:03], we want Image Motion, Increase, barber pole, plus 3 steps/On.
196 52 52 Mattingly: Okay. Barber pole plus 3 at 15.
196 52 56 Peterson: That's affirmative.
196 53 04 Mattingly: Okay. Is that - is that all for about 10 minutes, please?
196 53 08 Peterson: That's affirmative.
196 53 10 Mattingly: Okay.
196 54 12 Duke: Houston, 16.
196 54 13 Peterson: Go ahead, 16.
196 54 19 Duke: Okay. I think, looking back at the procedures during the back side pass, I think I've figured out what's wrong with the LM, but I'm not really sure.
196 54 31 Peterson: Okay. Go ahead.
196 54 37 Duke: Okay. With the changes from yesterday that were not updated this morning, it looks like to me on Pages 16 and 17 of the Timeline Book, we came out of there with no AC power. Both Inverter breakers are Open.
196 52 58 Peterson: Roger; understand. Due to the changes yesterday that were not updated today, on Pages 16 and 17 of the Timeline Book, you came out without AC power.
196 55 10 Duke: That's apparently what happened, and I think that the ATCA/PGNS needs AC to fire the jets - but I'm not really - to get the control voltage, but I'm not really positive.
196 55 21 Peterson: They're saying here, Charlie, that AC is not required to fire the jets.
196 55 28 Duke: Okay. Then that didn't - hmm. Okay. Well, I don't know what happened, then.
196 55 34 Peterson: Roger. Don't worry about it, Charlie. We're not.
196 55 48 Duke: Okay; fine. It's just - disappointing. Except for that one switch, I left everything just like you wanted it.
196 56 01 Peterson: Roger.
196 59 55 Peterson: Again, Casper, as a reminder, you should now be about through configuring the camera for orbital science, and we're about two and a half minutes away from the Pan Camera, Operate.
197 02 57 Peterson: Casper, we've got a REFSMMAT for you any time you can let us have the computer.
197 03 13 Duke: Okay; you got - computer.
197 03 19 Peterson: Right.
197 03 24 Young: Okay, Houston. You have the computer.
197 03 27 Peterson: Roger; copy.
Public Affairs Officer: This is Apollo Control, that completes our tape playback we'll continue now to stand by live. Although we haven't gotten confirmation from the crew our telemetry data shows that the sub-satellite has been ejected, from the CSM, from the service module, the SIM bay. And we expect that we will be getting a confirmation from the crew on that also, however at the present time they are quite busy with the cameras on board. And we've been keeping the amount of conversation and the amount of request we've been making on the uplink to a minimum.
197 08 51 Peterson: And, Casper; would you go High Gain, Auto.
197 15 30 Peterson: 16, Houston. I've got some SPS cue card changes, and have a request on Secondary Propellant Pressure switches Open, if somebody can copy.
197 15 46 Mattingly: Could you wait on that SPS cue card stuff until I get through the photo strip, Don?
197 15 51 Peterson: Roger.
197 15 52 Mattingly: Will it be too crowded for that?
197 15 53 Peterson: Negative. I don't think so.
197 15 59 Mattingly: Say again, Don.
197 16 01 Peterson: We'll hold off. Go ahead with your strip.
197 16 18 Peterson: Okay. Looks like we're about a minute from Boboland [?].
197 16 24 Mattingly: Okay. I'm all set; thank you. And I'm starting with an f/8 and 1/250. And I'll wait for you to tell me when to change settings.
197 16 35 Peterson: Roger. We'll do it.
197 22 54 Mattingly: Don, one of the things that I just noticed in passing Alphonsus is the dark halo craters. And each of those has a little amount of light material inside of the crater itself, just like all the rest of these craters around here. So maybe a dark halo is really an early stage in development.
197 23 15 Peterson: Roger. We copy. And in a couple of minutes, Ken, we'll have you go to f/5.6. I'll call you on time.
197 23 32 Mattingly: Thank you.
197 24 55 Peterson: Okay, Ken. In about 15 seconds, you should be north of Bullialdus, and we'll have you go to f/5.6 at that point.
197 25 10 Duke: Hey, right now, I'm just passing Lassell C, looking straight down.
197 25 14 Peterson: Roger.
197 25 56 Peterson: Okay, Ken. Go to 5.6 as you get up - a beam of Bullialdus.
197 26 09 Mattingly: Okay. Abeam Bullialdus; I'll go to 5.6.
197 26 12 Peterson: Roger.
197 27 03 Peterson: Okay, Ken. In about a minute or so, we'll be up by Helmet. And, at that time, we'll want to change the shutter to 1/125.
197 27 18 Mattingly: Okay.
197 28 10 Peterson: Okay, Ken. Looks good on 1/125 on the shutter, and you should be coming up by Helmet pretty soon now.
Public Affairs Officer: This is Apollo Control at 197 hours, 41 minutes [197:29]. Our Return to Earth Officer is in the process of computing a preliminary set of numbers for the Trans-Earth Injection maneuver, That maneuver will start Apollo 16 on its way back to Earth [and] is scheduled to start at 200 hours, 33 minutes [and] 20 seconds [200:21:30] Ground Elapsed Time. And the burn will be performed with the spacecraft Service Propulsion System engine will be about a 2 minute, 50 second maneuver. And with the completion of that burn a splashdown time will be set at 266 hours, 2 minutes [and] 7 seconds. That time is subject to change a little bit but the time of Entry Interface will be quite fixed once the Trans-Earth Injection maneuver has been performed. We also have some times for Acquisition of Signal with and without the Trans-Earth Injection maneuver. If the burn is performed as planned, the Acquisition of Signal time as Apollo 16 comes around from behind the Moon after performing the burn will be 200 hours, 43 minutes [and] 10 seconds [200:31:20]. If for some reason the burn is not performed as scheduled on the 65 revolution, the Acquisition of Signal time will be 200 hours, 52 minutes [and] 50 seconds [200:41:00]. Looking a little farther down the Flight Plan, the time now for Mid-Course Correction Number 5 is 217 hours, 34 minutes. And the time for the CSM EVA is 221 hours, 5 minutes. Correction on that the - yes, that would be hatch open [at] 221 hours, 5 minutes for hatch open, and hatch closed at 222 hours, 15 minutes. In Central Standard Time that would compute to 4:47 pm Central Standard Time the hatch open and 5:57 pm central standard time for the hatch closed. And again the splashdown time that we are looking toward is 266 hours, 2 minutes 7 seconds. We expect that that number will probably be updated somewhat following the Trans-Earth Injection maneuver. Apollo 16 at the present time is in an orbit with a high point or apocynthion of 66.5 nautical miles and a low point above the lunar surface of 52.4 nautical miles.
Public Affairs Officer: This is Apollo Control. We would like to point out that these numbers that were just passed along for such events as TEI, the Mid-Course Correction, the Trans-Earth EVA and splashdown all do not take into account the fact that we are expecting to do a clock update. That clock update will move the clock ahead about 21 hours [and] 50 minutes. That 21 hours [and] 50 minutes will have to be added to the times that we have given - to the GET times that we have given, in order to keep them in sync with the time we'll be using in Mission Control once the GET update has been done. We still haven't settled precisely on when that update will be made. The primary purpose for it is to bring the clocks into synchronization with the Flight Plan. At this point there are two things we can do. We can either go through the Flight Plan as we have been doing up to now and changing all of the times that are in the Flight Plan to make them agree with the clock or, and this is a more simple procedure, we can simply change the clock to make it agree with the times that are already in the Flight Plan. This eliminates a great deal of changes that have to be made to the Flight Plan and will be done at a convenient point. However, just when that point will be reached we haven't decided on yet. It will be sometime after the Trans-Earth Injection maneuver. The Central Standard Times, of course, are: not affected and they will remain the same for the hatch open, hatch close. Again, that Central Standard Time for the Trans-Earth EVA hatch open is 4:47 pm Central Standard Time [and] hatch close 5:57 pm Central Standard Time. The playing that we do with the clocks here in the control center and on the spacecraft will not affect those Central Standard Times.
197 37 32 Peterson: Okay, Ken. We show Pan Camera T-stop now.
197 37 46 Mattingly: Okay. And it's in Standby. I've completed the photo strip. I have 160 frames on magazine RR. And magazine Victor, I finished it off with, and it now has 160 frames showing.
197 38 01 Peterson: Roger. Understand 160 frames on RR and on Victor. We'll also go Mapping Camera, Off, now.
197 38 16 Peterson: And on she Mapping Camera -
197 38 17 Mattingly: It's Off.
197 38 18 Peterson: Okay. We'll wait a few more seconds here, 30 seconds total. And then we can go Mapping Camera, Standby.
197 38 31 Peterson: Okay. And you can go Pan Camera, Off, now. And you can go Laser Altimeter, Off.
197 38 46 Mattingly: Okay. The Laser's Off. The Pan Power's Off. And I'm going to Standby on the mapper.
197 38 52 Peterson: Roger.
197 39 02 Mattingly: And the Image Motion is Off.
197 39 04 Peterson: Roger. Okay. And then we want to do Mapping Camera, Retract.
197 39 53 Mattingly: Mapping Camera's Retracting .
197 39 56 Peterson: Okay.
197 41 01 Mattingly: Okay, Don. You want to talk about that - the cue card change, or whatever it was you were getting ready to do awhile back?
197 41 07 Peterson: Roger. And verify that you've got Mapping Camera/Laser Altimeter Cover Closed.
197 41 16 Mattingly: No, sir, I haven't. Just now got the camera in.
197 41 20 Peterson: Okay; then we want Mapping Camera/Laser Altimeter Cover Closed, and enable all jets.
197 41 28 Mattingly: Okay. We got the Cover Closed.
197 42 07 Mattingly: Okay. The jets are configured.
197 42 09 Peterson: Okay. We need to go to Block on the computer. And, Ken, it looks like that circ flag has not been set. I'm sorry; it's set. It needs to be reset.
197 42 27 Mattingly: You :mean - you mean the numbers, Verb 45?
197 42 33 Peterson: Stand by a minute. Verb 45, Ken.
197 42 54 Peterson: Okay, Ken. And we've got one note on the Service Module RCS system. I got a TEI pad, couple more changes to the Flight Plan, and a SPS cue card change for you. And you can copy them in any order you want.
197 44 15 Mattingly: Okay. Let's start with your RCS notes. And then following that, let's take the Flight Plan, and the - I think - Let's take the RCS, the cue card, the Flight Plan, and finally the pads.
197 44 30 Peterson: Okay. The RCS note is we want the Service Module RCS Secondary Propellant Pressure switches, four, Open. And that's to prevent the primary fuel tank depletion during TEI.
197 44 47 Mattingly: Don, did you copy?
197 44 54 Peterson: Roger, Ken. I copied you. And I had started reading there on the RCS note. Did you read that?
197 45 02 Mattingly: No, sir. I hadn't [garble]...
197 45 03 Young: No, we missed you.
197 45 07 Peterson: Okay. I'll - I'll try it again here. The Service Module RCS Secondary Propellant Fuel Pressure switches, four, Open. And the purpose for that is to prevent primary tank fuel tank depletions during TEI.
197 45 31 Young: Do that right now?
197 45 36 Peterson: Stand by one. That's affirmative. That's affirmative. We want to go ahead and do it now.
197 45 58 Young: Got four, Open.
197 46 02 Peterson: Okay. Now the SPS cue card. Let me know when you're ready to copy.
197 46 16 Mattingly: Okay, Don. Go ahead. And why don't you give me an outline of what is first, so I have some idea of what to do, and then I'll work on the card. We can go back and do it in detail.
197 46 24 Peterson: Okay. First of all, about a third of the way down the page, we've got a note on the - on PNGS operation for TEI, and then we've got a couple or three words to add down about nine lines from the bottom on the gimbal trim and verify manual thrust vector control. And we're gonna say there, "Except Yaw." And seven lines from the bottom, we're going to have you open the Pitch 2 and Yaw 2 Battery B circuit breakers to keep the Secondary system from getting an - or sensing an overcurrent and shutting itself down. And on the back of the card, we're going to reclose those two circuit breakers after the Delta-V Thrust Stop.
197 47 13 Mattingly: Okay. Is there some reason you think that we need that added protection this time?
197 47 19 Peterson: I guess it's just a feeling that if you get into TEI and you lose the primary system and you're on the Secondary system, you don't want the Secondary system to - to sense an overcurrent and shut down. And we're gonna pull these circuit breakers to make sure that that control system continues to function.
197 47 4l Mattingly: Okay. That's always the case. I just wondered if there was some reason that you were suspicious that might be more appropriate thing to say this time.
197 47 51 Peterson: Negative. We don't have any - any evidence that says that's likely to happen or any more likely to happen.
197 48 06 Mattingly: All right. Is that the - that's the context of the changes?
197 48 11 Peterson: That's affirmative.
197 48 21 Mattingly: Okay. Now let's take it from the top.
197 45 24 Peterson: Okay. About a third of the way down the page then, we want to add, "PUG Mode, Aux; Oxidiser Flow Valve, Normal, Secondary." And in a comment, we want to add - "Do not ...
197 48 49 Mattingly: Would this be - Is there something different about this than what we've done here - for all of the other burns?
197 49 03 Peterson: I think just the "PUG Mode, Aux" is the only change.
197 49 14 Mattingly: Okay. You want to go PUGs, Mode to Aux. You want to leave the Oxidiser Flow Valve in Secondary. And the position of the valve in Normal. Is that correct?
197 49 26 Peterson: That's affirmative. And we do not want to move the Oxidiser Flow Valve during the burn.
197 49 35 Mattingly: Okay.
197 49 36 Peterson: Okay. Then nine lines from the bottom, where it says "Set GPI trim, verify MTVC," we want to add the words, "Except Yaw."
197 49 57 Mattingly: Roger.
197 50 01 Peterson: Okay. And seven lines from the bottom, we'd like to add "Circuit breakers Pitch 2 Battery B, Open, and "Yaw 2 Battery B, Open."
197 50 20 Mattingly: Okay.
197 50 23 Peterson: Okay. And on the back of the page, after the "Delta-V Thrust, two, Off," we want to close those circuit breakers. That's Pitch 2 Battery B, Closed, and Yaw 2 Battery B, Closed.
197 50 43 Mattingly: Okay.
197 50 46 Peterson: Okay. That does it for the cue card.
197 51 08 Mattingly: All right. Give me the Flight Plan now, if you will, please.
197 51 11 Peterson: Okay. At 198:40 in the Flight Plan.
197 51 21 Mattingly: All right.
197 51 23 Peterson: Okay. We want to add a waste water dump to 10 percent.
197 51 34 Mattingly: Okay. We'd have gotten that down further, but we just - just couldn't get it all done the last time.
197 51 39 Peterson: Okay. And that's somewhere between the P52 and AOS, anywhere you want to stick it.
197 51 47 Mattingly: Okay.
197 51 52 Peterson: Okay. And at 199:45 [199:33] -
197 52 10 Peterson: At 199:45 [199:33], we want to add ...
197 52 12 Mattingly: Don, you gave me that at 199:40, didn't you?
197 52 16 Peterson: Negative. That ...
197 52 17 Mattingly: You gave me that waste water dump at 199:40 or 45?
197 52 21 Peterson: Negative ...
197 52 22 Mattingly: You had me -
197 52 23 Peterson: ... It was 198:40 [198:28]on the waste water dump.
197 52 29 Mattingly: Okay. That makes more sense. Thank you.
197 52 35 Peterson: And at 199:45 [198:33]...
197 52 37 Mattingly: All right. Go ahead.
197 52 39 Peterson: At 199:45 [198:33], we want to add "Load EMP 509."
197 52 50 Mattingly [Young in CM transcript.]: Okay. "Load 509 at 199:40 [199:28]."
197 52 55 Peterson: Okay. That's 199:45 [198:33]. And now I've got the preliminary TEI-64 pad.
197 53 15 Young: Go ahead. Over.
[Short segment of CM transcript follows.]
197 54 59 Duke (onboard): Some chicken soup?

We'll get you one for the final pad. And we're about a minute from LOS now. You can try a readback if you want.
197 56 16 Young: Okay. Pre-TEI-64, SPS/G&N; 38 ...
197 56 24 Peterson: 3833 ...
197 56 25 Young: 38332; plus 0.61, plus 0.95; 200:33:20.44; plus 3265.6, plus 0808.0, minus 0215.1; 180, 000, 000; plus 21.7; plus 3371.0, 2 minutes 42 seconds, 3351.7; sextant star 23, 183.7, 37 and a half; latitude, minus 7.2, minus 156.0, 1049.4; 36277 ...
[Loss of Signal at about 197:57.]
Public Affairs Officer: This is Apollo Control. We lost radio contact with Apollo 16 while John Young was in the process of reading back those numbers. The numbers that he was reading back to us are the preliminary numbers that will be used for the Trans-Earth Injection maneuver. That maneuver occurs at a Ground Elapsed Time of 200 hours, 33 minutes [and] 21 seconds. And, it will be performed using the spacecraft Service Propulsion System engine [and] the primary guidance and navigation system. It comes at the very end of the 64th revolution while the spacecraft is behind the Moon. We'll get our first report on the outcome of the maneuver as the spacecraft comes into acquisition on the 65th revolution of the Moon. The total velocity change is predicted at this point to be 3,371 feet per second and that will be achieved by burning the Service Propulsion System engine for 2 minutes, 42 seconds. With that burn performed nominally we would predict a time of entry interface of 265 hours, 49 minutes [and] 12 seconds leading us to that splashdown time of 266 hours, 2 minutes [and] 7 seconds. The amount of time the spacecraft spends on the shoots after entry interface seems to be a little bit more variable than the time of entry interface. But, those times should not change a great deal given a nominal SPS Trans-Earth Injection maneuver. We'll be reacquiring Apollo 16 in 42 minutes as the spacecraft went around the corner of the Moon we were showing an orbit of 66.6 nautical miles by 52.6. At 198 hours 11 minutes this is Apollo control, Houston.
[No CM transcript for this back-side pass.]
[Start Lunar Rev 64 at 198:32]
[Acquisition of Signal at 198:47]
Public Affairs Officer: This. is Apollo Control at 198 hours 54 minutes. And we have just reacquired Apollo 16 now in its 64th revolution of the Moon, this will be the last complete orbit of the Moon that Apollo 16 will make. At the end of the 64th revolution, the crew will burn the Service Propulsion System engine for 2 minutes and 42 seconds to start them on their way back to Earth for a 65 hour, 29 minute flight return to Earth. During this revolution while on the frontside of the Moon in radio contact, we'll be passing up the final set of numbers that the crew will put into their onboard computer for the spacecraft's Service Propulsion System burn. And we'll be getting final looks at all of the CSM systems prior to committing to Trans-Earth Injection.
198 47 35 Peterson: 16, Houston. How do you read?
198 47 40 Mattingly: Loud and clear, Pete. How are you?
198 47 42 Peterson: Loud and clear.
198 48 27 Mattingly: Okay, Houston. The gyro torquing angles on the P52 option 3, with the star angle difference all balls, minus 0.032, plus 0.001, plus 00, - plu - excuse me - plus 0.034. And that was at a GET of 198:24:35. And those angles were so small they weren't torqued because we went into the Option 1.
198 49 00 Peterson: Roger.
198 49 20 Peterson: And, 16, I've got a map update - rev 65 - at about - 200 hours 30 minutes in the Flight Plan. TEI -.
198 49 42 Mattingly: Okay.
198 49 45 Peterson: Okay. It's around 65 instead of 76. And the numbers are 200:07:27; 200:31:33 [200:19:43]; with TEI, 200:43:09 [200:31:19]; without TEI, 200:52:48 [200:40:37].
198 50 18 Mattingly: Okay. 200:07:27, 31:33, 43:09, and 52:48.
198 50 26 Peterson: That's affirmative.
198 50 57 Mattingly: (Laughter) I would suspect that you can probably throw this one back in that jett bag, too, then. There. Thank you.
198 51 13 Peterson: And, Ken, you're on air to ground.
198 51 19 Mattingly: Thank you.
198 52 31 Peterson: Okay, 16. I've got some numbers on the RCS Delta-V. I believe they're at 200 hours and about 15 minutes in the Flight Plan now.
198 52 45 Mattingly: Okay. Go ahead now.
198 52 48 Peterson: Okay. Pre-TEI, you've got 75 feet per second; post-TEI, you've got 111 feet per second.
198 53 01 Mattingly: Okay. Pre is 75 and post is 111.
198 53 05 Peterson: That's affirmative.
198 53 10 Roosa(?): And, Ken, have you got a couple of minutes to listen to a few words about servo loop.
198 53 19 Mattingly: Okay. Go right ahead, Stu.
198 53 21 Roosa: Okay. That's a real good system you've got on your second loop. We have got the simulator swinging right with the characteristics of your spacecraft. And this is the way it's going to look to you if you have to use it. Prior to ignition, the gimbal is going to be oscillating plus or minus - approximate - at about a degree - 0.9 - something like that or, in other words, 1.8 peak to peak. But once you get Thrust On, there's a side load on your bell from the LOI burn, and this side load acts as a damper. Since the load is cyclic, it really doesn't matter which direction the load is; it damps out. Under CMC control, it will damp out in a few seconds and burn very steady. In SCS, Auto, it damps almost immediately and then is steady throughout the rest of the burn. In Rate Command, however, since you're continually pulsing it with an input, it continues to oscillate pretty much at this same magnitude, or amplitude, throughout the burn. However, as far as you controlling it, it really doesn't matter. However, sitting in the simulators we don't get the real live shake effect that you're going to get. The spacecraft is going to shake and shudder; however, your attitude will remain virtually unchanged. And, I guess, the only advice that I could say would be that if you download - if you could go to SCS, Auto, you would save those excessive clutch currents that you get under Rate Command with this continual oscillation. And I guess I'll stop there, if you've got any questions.
198 55 26 Mattingly: No, that sounds - that's good information, Stu. I'm glad to hear that. Do you - you got any cute tricks in the back of your mind on how you can download from Rate Command and then go back to Auto without getting a big transient due to the mistrims?
198 55 45 Roosa: No. I - I think - now I tried it - purposely having at least, say, a degree mistrim and - when I would switch, and you'll get the transient, but the bell will - will steady out. Now, I think going ahead and flying it in Rate Command is - is acceptable; however, you are - you are getting the bell oscillating, and you are putting, you know, the currents through there. This attitude...
198 56 14 Mattingly: Okay. I get the - Sounds like - if you could - you could damp the rates - damp the oscillations quickly by getting it into Rate Command - I mean the - Auto and then use the old thumbwheel procedure to change the pointing accuracy if you aren't pointing in the right direction.
198 56 44 Roosa: Yeah. You - you don't have much control with that - with that thumbwheel in - in the Auto. I think, probably, I would take it in Rate Command, go back to my attitude, recycle my BMAGs, uncage them again at my - at the attitude I wanted, and then accept the trim - the mistrim in the - in the gimbal and - and let that damp out. I think you're going to be hard put to try to guess - guess your thumbwheel setting. However, let us think about that a little bit; and, also, I'd like to say this has been checked. I talked with North American this afternoon. This all agrees with the hardware evaluator, as far as our characteristics, so I think we're pretty close to your spacecraft.
198 57 39 Mattingly: Okay. That's outstanding. Sounds like you guys have done a mighty thorough job. My first choice then would be to - I think, based on what you said right now, just do the natural thing and take the oscillations unless they're excessive, and look - just download in the normal manner and ride it out.
198 58 01 Roosa: Okay. That sounds - I think that's very ...
198 58 03 Mattingly: So, as the first choice, I think we'll do the normal thing and burn CMC.
198 58 12 Roosa: By all means, yes. CMC is - is prime, or you can - you can download ...
198 58 15 Mattingly: Yes, okay.
198 58 16 Roosa: ... You'll be in Rate Command, and you will have the bell shaking. It'll start to damp a little bit; but every time you hit with an impulse, why, you'll excite the oscillation again.
198 58 31 Mattingly: Okay. Thank you very much, Stu.
198 58 39 Roosa: Roger.
Public Affairs Officer: This is Apollo Control at 199 hours, 11 minutes. That was Astronaut Stuart Roosa who has been running a number of simulations in the simulators here at the Manned Spacecraft Center reproducing the problem that has existed in the thrust vector control in the Apollo 16 backup guidance system. He was going through with Ken Mattingly what the crew on Apollo 16 -
198 59 19 Roosa: And one other thing, Ken. After convincing you that that system is - is real good, which we believe it is, we'd like to say - and I'm - I'm assuming that you would do this anyway - that if everything isn't checking out real good - primary system-wise or anything else, you'll just come around and let us take another look at it.
198 59 42 Mattingly: Yes, sir. if there's any problem with the primary system or anything abnormal, we'll come around and talk it over.
198 59 49 Roosa(?): Okay. Very good.
199 00 43 Peterson: 16, would you verify BMAGs in Rate 2.
199 00 53 Mattingly: Will now. Thank you, Don.
199 00 54 Peterson: Roger.
199 01 02 Peterson: And, 16, if you'll give us the computer, we'll up-link a state vector and the target load for you.
199 01 14 Mattingly: You have it.
199 01 15 Peterson: Roger. Thank you, and go Auto on the High Gain.
Public Affairs Officer: This is Apollo Control. Our spacecraft communicator for the Trans-Earth Injection maneuver will be astronaut Don Peterson. He is accompanied at the Capcom console by astronaut Stu Roosa, who a few moments ago was discussing with Ken Mattingly from his experience in the simulators what Mattingly and the crew of Apollo 16 should experience. If for some reason they had to switch over to the backup guidance system to control this Trans-Earth Injection maneuver, with the problem that they have had with the thrust vector control, how that system would control, and what they should expect to see and feel. In essence, Roosa's comments, from operating with a similar system in the simulator, were that the backup system should control very well. But there will be some oscillations due to the oscillation in one of the two axis of control of the thrust vector control system which transmits the commands to the SPS engine bell that gimbal it from side to side and up and down. In the yaw direction there are some oscillations in the backup control mode. However, Roosa found that with a precise sort of a set up that the Apollo 16 spacecraft has, and what he described as some sideloads that are characteristic of the way this engine is burning. It will damp out most of the oscillation shortly after the engine ignites, and would control properly, and would control the burn very well. This again, we'd reiterate, is a backup control system from everything that we've seen on the primary control system is expected to function normally and give the same excellent account of itself that it has in previous burns. The advice to Ken Mattingly, in the event that there is some unforeseen problem with the primary control system, is that he would go on around, not perform the burn, let us take a look at the primary system back on the frontside of the Moon. See if there would be any way of restoring that, and if not, the burn would be performed with the backup system which we would also expect to do a very good job of controlling the maneuver.
199 02 35 Peterson: 16, we'd like to go to a different configuration on the cryo O2 Tanks 1 and 2, Auto, and Tank 3, Off.
199 02 49 Mattingly: Got it.
199 04 27 Peterson: Okay, 16. It's your computer, and I've got the TEI pad any time you're ready.
199 04 58 Mattingly: Okay, Pete. Go ahead.

199 09 06 Peterson: The readback's correct, 16.
199 09 12 Mattingly: Okay. Thank you.
Public Affairs Officer: This is Apollo Control. Those were the final set of numbers that the crew will use for the Trans-Earth Injection maneuver. And they were virtually unchanged from the preliminary which were read up on the previous revolution, the time of ignition remains the same 200:33 21 seconds, the total velocity change 3,370.9 feet per second and the burn duration is unchanged 2 minutes 42 seconds, and the time of re-entering the Earth’s atmosphere also unchanged, [at] 265:49:12 seconds. We have about 45 minutes remaining before we lose radio contact with Apollo 16, on this revolution. When next we reacquire radio contact with the spacecraft they'll be at the start of their 65th revolution and should be on their way back to Earth.
199 10 54 Peterson: And, 16, I've got some block data, TEI-65.
199 11 09 Duke: Okay. Go ahead.

199 12 52 Peterson: The readback's correct, 16.
199 13 53 Mattingly: Hey, Don. Could you have someone check on the proper exposure settings for CEM film for post-TEI?
199 14 01 Peterson: Will do, Ken.
199 14 06 Mattingly: Thank you, sir.
Public Affairs Officer: Apollo 16 at the present time is passing over the Descartes landing site for the final time on this mission. We have about 38 minutes now until we lose radio contact on this revolution.
199 17 18 Peterson: 16, I've got about four more updates to the Flight Plan, any time you want to copy. At about 200 hours and 43 minutes is the first one.
199 17 32 Mattingly: Okay. Go ahead.
199 17 35 Peterson: Okay. There's a list of items at 200 hours and 43 minutes, and we want to add to that list "Pan Camera V over H override to high altitude."
199 17 51 Mattingly: Okay, Pan Camera V over H to high.
199 17 56 Peterson: And at 200 hours 46 minutes, we want to change from "Barber pole plus three steps," to "Barber pole plus two steps."
199 18 10 Mattingly: Okay. That's plus two.
199 18 12 Peterson: Roger. And at 200 hours and 56 minutes, we want to change from "Gamma Ray, Deploy" to read "Gamma Ray, Deploy to 8 feet," and that's "59 seconds."
199 18 31 Mattingly: Okay. Gamma Ray, Deploy at 8 feet, 59 seconds.
199 18 40 Peterson: Okay. And at 201:082 we've got "Maneuver angles to Moon UV attitude are roll, 174; pitch, 212; yaw, 64; and the High Gain Antenna angles are Pitch, minus 73; and Yaw, 12."
199 19 09 Mattingly: Okay; 174, 212, and 064 for the attitude, and High Gain, minus 73 and 12.
199 19 18 Peterson: Readback correct, and that's all the Flight Plan updates we've got right now.
199 19 25 Mattingly: Okay, Don. Down here where it says "Pan Camera, Mapping Camera film should be expended," I'm gonna let those things run until you guys tell us that you're either tired of taking pictures or something, because we're not going to run out, I don't imagine - at least not at this point.
199 19 44 Peterson: Okay, 16. Understand the Pan Camera will probably run out, but the Mapping Camera may take quite awhile.
199 19 53 Mattingly: Okay. I suspect it's probably to our advantage, even though the cutter works good, that we probably ought to go ahead and run it out. That's your call though.
199 20 05 Peterson: Okay, 16. I think that's what we plan to do.
199 20 10 Mattingly: Okay.
199 20 22 Peterson: And, 16, it'll take about 3 hours to get rid of that mapping camera film, if we run it all the way out.
199 20 30 Mattingly: Okay. Is that what you want to do or did you want to just go ahead and cut it tomorrow? It's no difference to us.
199 20 39 Peterson: We'll let it run out, Ken.
199 20 44 Mattingly: Okay.
199 10 Peterson: 16, can you verify that the sub-satellite deployed on time?
199 18 Mattingly: Yes, sir. Sure can.
199 21 Peterson: [Garble].
199 23 Young: How's it doing?
199 38 Peterson: Okay. I guess we're not able to see it until the LM electrical power runs out.
199 26 Mattingly: Yes, sir. It went on time. Of course, it was in the dark and we couldn't see it to verify it visually, but - all indications were that everything was a normal deployment.
199 57 Peterson: Roger. Understand.
199 05 Mattingly: And you can tell all our friendly G&Cs there, Don, that I don't understand it, but in 100 seconds, EMS now only shows a 0.2 change, which looks like the EMS gets better as time goes on.
199 18 Peterson: Roger. Understand you think the EMS is getting smarter.
Public Affairs Officer: That was Ken Mattingly reporting that the sub-satellite was launched from its position in the Scientific Instrument Module bay of Apollo 16 on time. The connection between the Lunar Module batteries and our ability to turn on the sub-satellite [to] begin receiving data from it is that the Lunar Module and the sub-satellite operate on the same frequency. The Lunar Module, of course, is no longer - we're no longer able to command it. It will not be impacted into the lunar surface; however, its communication system is still functioning and it is still putting out radio frequency energy - still transmitting and for that reason we're not able to activate the sub-satellite begin receiving data from it. This will continue until the Lunar Module batteries go dead.
199 30 38 Mattingly: Houston, is it okay for 16 to go to the burn attitude?
199 30 43 Peterson: Stand by one. Okay, 16. You can go to burn attitude.
199 30 51 Mattingly: Okay. Thank you, sir.
199 32 03 Peterson: 16, would you verify Limit Cycle switch, Off.
199 32 10 Mattingly: No. As a matter of a fact, it's on right now.
199 32 16 Peterson: Okay. We'd like to have that switch Off, please.
199 33 07 Peterson: And, 16, we'd also like you to verify once more, although we're sure you're going to do it this way anyway, that you're going to leave the Optics Power switch on during the burn, because that will decrease the probability of the - of the glitch occurring.
199 33 26 Mattingly: Okay. I didn't realize that it would. We would have left it on, but thank you for telling us.
199 33 31 Peterson: Roger.
Public Affairs Officer: This is Apollo control. A few moments ago Ken Mattingly reported the spacecraft was beginning to maneuver to the proper attitude for the Trans-Earth Injection burn. We expect when they do that we'll momentarily lose lock on with the High Gain Antenna. In fact, we are hearing a bit of increase in the noise level now and we just had break in the lock. We'll be reacquiring [and] should have a good solid lock up again shortly. In the mean time we'll continue to have rather noisy communications between the ground and the spacecraft. And communications controller here INCO reports that we should be locking up shortly on an Omni antenna. And we've just done hat. We've got good solid lock on now. As an additional note of interest on the interference problem that we're having with the Lunar Module transmitter which is as we said on the same frequency as the sub-satellite. We're predicting that the LM batteries will die at about 211 hours ground elapsed time give or take an hour and a half. So at about 211 hours we should be able then to command the sub-satellite and to begin receiving data from it. Now there is a small possibility that we'll get a lock on the Lunar Module for a long enough period of time that we can command it to shift frequency so that we no longer have the interference problem. However, as soon as the LM breaks lock it will again revert to the original frequency so this would only be a temporary assist in the problem. And, until 211 hours plus or minus an hour and a half we don't expect to be getting any consistent data from the sub-satellite. We' re showing now 19 minutes, 25 seconds until we lose radio contact with Casper. As the spacecraft goes around the corner behind the Moon it should be in the proper attitude for the burn and flight controllers here will be getting a last look at all the systems and we'll be giving the Apollo 16 crew [the] Go for Trans-Earth Injection.
199 40 01 Peterson: Okay, 16. I've got those camera settings for after TEI. Can you tell me you're ready to copy?
199 40 12 Mattingly: Go ahead.
199 40 14 Peterson: Okay. For the first 15 degrees past the terminator, the settings are 5.6, 1 over 125, and infinity; from 15 degrees to 30 degrees, it's 5.6, 1 over 250, and infinity; and past 30 degrees, it's 8, 1 over 250, and infinity.
199 40 48 Mattingly: Okay. Thank you, Don. The first 15 degrees, it's 5.6, 1/125; and, from 15 to 30, it's 1/250; and, from 30 on, it's f/8 and then 1/250. Thank you.
199 41 00 Peterson: Roger. And just a couple of additional comments here. The P20 attitude is going to differ slightly from what you've got in the Flight Plan, due to the fact; that we're using a different TEI REFSMMAT. It's a very small change and probably not very significant. But we didn't want it to surprise you. And the TEI rev is different, of course. That's going to give us a slightly different terminator, so we've been advised that you can turn the Mapping Camera and the Pan Camera on a couple or three minutes early, if you'd like since we got a lot of film.
199 41 39 Mattingly: Okay. We'll put those things on as soon as it's practical. And you - did you want to change the Noun 78 load, or are you just saying that that will give us a different set of gimbal angles?
199 41 53 Peterson: The Noun 78 load is correct, it'll just give you a slightly different set of gimbal angles.
199 42 00 Mattingly: Okay. Thank you.
199 42 02 Peterson: Roger.
199 42 09 Mattingly: And the 509 flag is set.
199 42 13 Peterson: Roger.
199 42 58 Peterson: And, 16, you're Go for TEI.
199 43 06 Young: 16 is going for TEI.
199 43 10 Peterson: Roger.
199 50 32 Mattingly: Okay, Houston. We have a successful star check.
199 50 36 Peterson: Roger. Understand successful star check.
199 50 42 Mattingly: That's affirmative.
Public Affairs Officer: Ken Mattingly has reported a successful star check[. That] is an indication that the spacecraft is in the proper attitude for the Trans-Earth Injection burn. We're now 4 minutes, 22 seconds away from loss of radio contact with Apollo 16. When next we reacquire spacecraft and crew should be on route back to earth. With a good TEI burn we would expect to reacquire Apollo 16 at 200 hours, 43 minutes [and] 10 seconds Ground Elapsed Time. If for some reason the burn is not performed on this revolution we would reacquire at 200 hours, 52 minutes [and] 50 seconds. The spacecraft weight prior to that 2 minutes, 42 second burn of the Service Propulsion System is predicted to be 38,232 pounds. Following the burn it will be 27,487 pounds. The difference of 10,845 pounds being in the propellant that'll be consumed in that 2 minute, 42 second burn. At the time of the Trans-Earth Injection maneuver the Lunar Module will be about 16 miles behind Casper - the Command and Service Module - and about one mile above. We're now three minutes away from loss of radio contact.
199 54 31 Peterson: About 45 seconds to LOS. See you coming home.
199 54 39 Young: Roger.
[Loss of Signal at about 199:55.]
Public Affairs Officer: Apollo 16 [is] now behind the Moon out of radio contact [and] 26 minutes away from the 2 minutes, 42 second burn that will start them on their way back to Earth. About 45 seconds prior to loss of radio contact Capcom Don Peterson advised the crew that we were coming up on loss of con - loss of signal and said "see you on your way home", and we got a terse roger from John Young at that point. Again, those time of acquisition with a normal Trans-Earth Injection burn 200 hours, 43 minutes [and] 10 seconds, [and] without the burn 200 hours, 52 minutes [and] 50 seconds. And, when we reacquire Apollo 16 they should be moving rapidly away from the Lunar surface. From the Apollo 10 mission where we had television of that particular portion of the mission we recall [a] very spectacular view of the Lunar surface out the window of the spacecraft. The Moon dropping rapidly away and shrinking rapidly in size. At 200 hours, 8 minutes [and] 38 seconds this is Apollo Control, Houston.

200 31 29 Duke (onboard): Okay. Just a second.
200 31 34 Young (onboard): I just got three pictures of it.
200 31 36 Duke (onboard): Hey, you got the one with the Earth in it?
200 31 38 Young (onboard): Yeah.
200 31 39 Duke (onboard): Beautiful.
Public Affairs Officer: This is Apollo Control. Now one minute, 30 seconds from reacquiring Apollo 16. Should the spacecraft for some reason not have burned it's Trans-Earth Injection maneuver we will be reacquiring in about 11 minutes. This burn with the Service Propulsion System engine was to be a 2 minute, 42 second burn producing a total change in velocity of some 3,371 feet per second, increasing the speed of Casper from 3,600 nautical - rather 3,600 statute miles an hour to about 5,900 statute miles per hour. In the course of this 2 minute, 42 second burn the Service Propulsion System engine would consume some 10,845 pounds of propellant. One of the things that's accomplished with the Trans-Earth Injection maneuver; and of course the prime objective, starting the spacecraft on its trajectory back to Earth. Well, also with this maneuver we set the splashdown time. From that point on there are minor corrections to the trajectory primarily to control the entry interface angle which is set at negative 6.51 degrees. Correction, negative 7.37 degrees. And with no problems of weather, and what we would have to change weather- Now we've just gotten the call of Acquisition of Signal right on time. We should be getting the first words from the crew. We're waiting for the antennas to lock up and communications are still quite noisy.
[Acquisition of Signal at about 200:31.]
200 31 38 Peterson: 16 Houston. How do you read?
200 31 43 Young: Hello there, Houston [garble] [Mattingly: "[Garble] Hello, there." in CM transcript.]
200 31 50 Young (onboard): Man, you come up like thunder. Wowee!
200 31 56 Mattingly (onboard): Okay, is the mapping camera out yet?
200 31 58 Duke (onboard): Yeah, it says barber pole.
200 31 59 Young (onboard): All right. The burn was nominal.
200 32 02 Mattingly (onboard): Barber pole. Still barber pole.
200 32 05 Duke (onboard): Let me get this [garble] before [garble] ...
200 32 07 Mattingly (onboard): Okay [garble]. operate it, though.
200 32 09 Young (onboard): [Garble] this book here.
200 32 08 Peterson: 16, I can't make out the words. We can hear you calling.
200 32 17 Young: Roger. [Garble.][From the CM Transcript: "The burn was nominal. We had - we just saw you rise."]
200 32 21 Peterson: Roger. Understand.
200 32 21 Mattingly (onboard): He already knows.
200 32 22 Duke (onboard): We got a high - we got a high gain angle?
200 32 26 Mattingly (onboard): Not until we get there. I - I think I set it.
200 32 28 Young (onboard): Well, what did - what did you set it to on this, Ken ?
200 32 30 Mattingly (onboard): On what?
200 32 31 Young (onboard): This camera.
200 32 32 Mattingly (onboard): What are you taking pictures of?
200 32 33 Young (onboard): [Garble] the Earth, and then me.
200 32 36 Mattingly (onboard): 1/250, f/8.
200 32 41 Duke: There's Omni Delta.
200 32 43 Young (onboard): Charlie, what's that result again?
200 32 45 Duke (onboard): I'm just about pitch and roll.
200 32 47 Young (onboard): Oh.
200 32 49 Mattingly (onboard): When we get to attitude, it'll be Pitch, 45; and Yaw, 320. It's set. I don't see how that's gonna work; it's not looking at the Earth [garble].
200 32 59 Young (onboard): Me, either. What is it? Just targets of opportunity out through there?
200 33 06 Duke (onboard): Man, we are climbing out.
200 33 16 Peterson: 16, Houston. Let's try it again.
200 33 22 Young: Do you read us now, Don?
200 33 23 Peterson: Roger. You're a lot better now.
200 33 28 Young: Roger, just saw you come up like thunder, and that's how we're coming up. Just going away from it like - nothing.
200 33 36 Mattingly (onboard): Hey, look at that beauty out there. Isn't that something? It's [garble] ...
200 33 39 Peterson: Roger.
200 33 40 Duke: It's better than an AB climb, Pete.
200 33 41 Peterson: Roger. Understand.
Public Affairs Officer: John Young, and Charlie Duke with the reactions very similar to what we've seen from previous crews as the spacecraft moves out very rapidly from the Lunar surface. We're sure that they are all eyes - every chance they get - looking out the windows and watching the Moon receding rapidly beneath them, growing rapidly smaller. The spacecraft velocity now is 7,957 feet per second.
200 33 42 Mattingly (onboard): Okay, Charlie, how about the Mapping Camera. Is it out yet?
200 33 47 Young (onboard): You have the burn status report, Charlie?
200 33 48 Duke (onboard): Yeah, it's out.
200 33 50 Mattingly (onboard): Okay, would you put the Mapping Camera to On?
200 33 52 Duke (onboard): Mapping Camera's going On, right.
200 33 54 Mattingly (onboard): Okay, Pan Camera to Operate.
200 33 55 Duke (onboard): Operate.
200 33 56 Mattingly (onboard): [Garble].
200 33 57 Duke (onboard): That came off.
200 33 58 Mattingly (onboard): Okay, Image Motion to Increase.
200 34 00 Duke (onboard): Okay.
200 34 01 Mattingly (onboard): [Garble] plus 2.
200 34 02 Duke (onboard): [Garble] ...
200 34 03 Mattingly (onboard): You have ...
200 34 04 Duke (onboard): ... [garble] barber pole plus 2?
200 34 05 Mattingly (onboard): You said it. One -
200 34 07 Duke (onboard): Barber pole. One - Got it.
200 34 11 Mattingly (onboard): Okay, have you got the Pan Camera to V/H [garble]?
200 34 14 Duke (onboard): Yeah.
200 34 15 Mattingly (onboard): Okay, I'll pick you up the status report. Why don't you get this one? It's all on the same page here.
200 34 19 Young (onboard): Okay. Okay, that's right.
200 34 21 Mattingly (onboard): Then I'll get one.
200 34 22 Young: Okay, Houston. We're working some mapping stuff. The burn was completed nominal. We'll give you the status report in - just as soon as we finish.
Public Affairs Officer: That was John Young reporting [that] the burn was completely nominal.
200 34 32 Duke (onboard): Look at that horizon thing, would you, you guys!
200 34 36 Young (onboard): Wonder if I can get that DAC on this thing.
200 34 38 Mattingly (onboard): Yeah, why don't you get the status report; I'll try to get the DAC going.
200 34 41 Young (onboard): Okay.
200 34 42 Duke (onboard): John, [garble].
200 34 44 Young (onboard): Here. Take the pictures, Charlie.
200 34 46 Duke: Roger. Give me a window.
200 34 55 Mattingly (onboard): Okay, I think we can get it out of that one.
200 34 57 Duke (onboard): Try the f/8, that one? Hold me.
200 34 59 Mattingly (onboard): Okay, now don't - don't stop it down any more.
Public Affairs Officer: Apollo 16 already 333 nautical miles above the Moon.
200 35 03 Young: Okay, Houston. Burn status report follows. There is no Delta-Tig. Burn time, 242.4. There was no trim. And the residuals were measured at 184, 005, and 351 degrees; 0.2, Vgx; 1.2, Vgy; 0.1, Vgz; all pluses; minus 19.1 Delta-Vc.
200 35 XX Young (onboard): Which was the fuel and which was the oxidizer, Charlie? 3.9?
200 35 45 Duke (onboard): The -
200 35 49 Young: 3.9 is the oxidizer and 5.2 is the fuel.
200 35 57 Peterson: Roger.
200 36 00 Duke (onboard): Man, did that beauty feel good! Ah! Must admit I feel good enough to [garble] ...
200 36 06 Young: It was really beautiful; that baby just hummed right out of there.
200 36 10 Peterson: That's great, John.
200 36 11 Young: She can really put on the power. It's - it's kind of refreshing to get a whole half g from her.
200 36 18 Peterson: Roger.
200 36 17 Mattingly (onboard): How about let me use the center window for a second?
200 36 25 Young: The boys are all at the windows taking pictures.
200 36 27 Peterson: Roger.
200 36 28 Mattingly (onboard): Get a pan.
200 36 31 Young: We got - we got some pictures of earthrise as we were climbing out. I bet they're really spectacular.
200 36 39 Peterson: Roger. Hope they come out nice.
200 36 45 Young: This Moon is really - is really a fascinating satellite. Boy, there's something new and different, and - and you can sure see a lot of variety from this view right here. This is almost ...
200 37 00 Duke (onboard): Look at that!
200 37 01 Young: This is even more spectacular almost than the Moon - than the Moon in earthshine when we're coming in here just ...
200 37 06 Mattingly (onboard): Boy, you can see old Neper and all that stuff.
200 37 09 Young: ... 5 days ago, or however long ago it was.
200 37 16 Peterson: Roger.
200 37 13 Duke (onboard): Let's see, am I looking north or south here, Ken?
200 37 16 Mattingly (onboard): North is that way.
200 37 17 Duke (onboard): Okay. I'm looking north. This is beautiful! You really get the idea it's a planet. It's just a -
200 37 28 Mattingly (onboard): Look over here.
200 37 30 Young: I think the general agreement in the cockpit is that morale around here just went up a couple of hundred percent.
200 37 46 Peterson: Roger. Morale looks pretty good here, too.
Public Affairs Officer: Apollo 16 climbing out now to 471 nautical miles above the Moon and that just updated to 480.
200 37 45 Duke (onboard): Hey, are we in SIM bay attitude?
200 37 47 Duke (onboard): Yes, sir.
200 37 48 Young (onboard): Got to have the High Gain.
200 37 51 Mattingly (onboard): (Laughter) How can I come around with a P00?
200 37 56 Duke (onboard): [Garble]
200 38 00 Mattingly (onboard): Can't believe that'll work yet.
200 38 09 Duke (onboard): [Garble]
200 38 l0 Mattingly (onboard): Okay, I'll let you back at the -
200 38 12 Duke (onboard): Yeah, I can get that [garble].
200 38 13 Mattingly (onboard): Thank you.
200 38 15 Young: Hey, Houston, how do you read on the High Gain?
200 38 19 Peterson: You're loud and clear now.
200 38 22 Young: Okay. I missed your last thing; we're switching over.
200 38 28 Peterson: Roger.
200 38 39 Young: We're now getting a view of - on the horizon, and there's Crisium. Way up north there, Charlie.
200 38 56 Mattingly (onboard): Hey, Charlie, be sure you get the florals [?] down there.
200 39 00 Duke (onboard): Right down there? Yeah, that's what I been doing.
200 39 02 Mattingly (onboard): No, wait a minute. No ...
200 39 03 Duke (onboard): I didn't see anything.
200 39 04 Mattingly (onboard): I don't think that's what I'm talking about.
200 39 05 Duke (onboard): Right down here?
200 39 06 Mattingly (onboard): This stuff over here. All those - take a strip that runs right out through here.
200 39 11 Duke (onboard): Okay.
200 39 12 Mattingly (onboard): And ...
200 39 13 Duke (onboard): Oh, yeah, yeah. I see it.
200 39 14 Mattingly (onboard): That stuff?
200 39 15 Duke (onboard): Uh-huh.
200 39 15 Peterson: 16, we need a Verb 58.
200 39 16 Mattingly (onboard): And - Yeah, it does keep on coming down here.
200 39 17 Duke (onboard): Yeah.
200 39 18 Mattingly (onboard): You can take a strip starting at the top of it and then come all the way to the bottom.
200 39 21 Young: You want a Verb 58?
200 39 22 Peterson: That's affirmative.
Public Affairs Officer: Apollo 16 now 583 nautical miles from the Moon and the velocity is dropping off down to 7,425 feet per second. John Young, so far, has been doing most of the talking reporting that Charlie Duke and Ken Mattingly were at the available windows taking pictures.
200 39 24 Mattingly (onboard): Is that what he said?
200 39 25 Duke (onboard): I don't know.
200 39 27 Young (onboard): What does that do?
200 39 30 Mattingly (onboard): Oh, I guess I didn't stop it in time.
200 39 34 Young (onboard): Didn't stop it in time?
200 39 36 Mattingly (onboard): I'm going - going to attitude. And - [garble] That's the problem with that program.
200 39 45 Young (onboard): What's that?
200 39 46 Mattingly (onboard): That thing goes off to - to play with itself and then manuevers - at 15-minute maneuvers; but you got 8 seconds at the end. If you don't hit Pro on it, it stops right there and it won't keep the rate drive going.
200 39 58 Young (onboard): No, but you have to watch it; it's okay.
200 40 00 Duke (onboard): That's just spectacular!
200 40 02 Mattingly (onboard): Well, I told you if you watch it. But you got to sit there and watch it. Which I ain't - guess I haven't ...
200 40 06 Young (onboard): At 10-minute intervals?
200 40 08 Mattingly (onboard): Huh?
200 40 09 Young (onboard): At 15-minute intervals?
200 40 10 Mattingly (onboard): No, if it takes you 15 minutes to get into attitude ...
200 40 12 Young (onboard): Oh, by then you got to - you got to hit the maneuver when you get there. Yeah.
200 40 16 Mattingly (onboard): Whenever it gets through with this, 10 seconds or 15 minutes.
200 40 18 Young (onboard): Yeah.
200 40 19 Mattingly (onboard): You got eight seconds grace.
200 40 24 Young (onboard): Should give you a tone warning or something.
200 40 26 Mattingly (onboard): Yeah.
200 40 27 Young (onboard): Look at that. Isn't that something, you guys?
200 40 30 Mattingly (onboard): It really is.
200 40 31 Young (onboard): It is really ...
200 40 33 Mattingly (onboard): I don't care. I'm sorry E.V. [?] isn't getting his pictures. To heck with that. (Laughter)
200 40 37 Young (onboard): Go ahead. I wish we had [garble].
[The next line of the transcripts shows the difficulty in interpreting the tape recordings.]
200 40 40 Duke: Hey, Pete, this is really a spectacular view. Wait until I get the camera clear.
[or...]
200 40 40 Young: Boy, Pete, this is really a spectacular view. Really get the curvature.
200 40 48 Peterson: Tell us about it.
200 40 47 Young: Yeah, the old crescent Earth coming up there.
200 40 49 Duke (onboard): Boy, look at it. There's old King right down there, the old crab.
200 40 53 Mattingly (onboard): See it?
200 40 54 Duke (onboard): Yeah, I can see it.
200 40 56 Young: The - the earthrise was just beautiful, and it just ...
200 41 00 Duke (onboard): Well, you look like [garble].
200 41 01 Young: ... came up like gangbusters. We were looking right out the window ...
200 41 02 Duke (onboard): Right down here.
200 41 03 Young: ... and there you came, and right now ...
200 41 05 Duke (onboard): [Garble] are?
200 41 06 Young: ... you're a - amost a - just a crescent Earth, Just a very sliver out there. And I tell you, we can hardly wait. I know we got a couple of things to do before we get there, but we're looking forward to it.
200 41 22 Peterson: Roger.
200 41 23 Duke (onboard): Did you tell them about sunset?
200 41 25 Mattingly (onboard): What about sunset?
200 41 27 Duke (onboard): I - I mean Earthset? Did you tell him about that? No?
200 41 30 Young: No. What about it?
200 41 31 Duke (onboard): I - I Just want to try it.
200 41 33 Young (onboard): Tell him.
200 41 34 Mattingly (onboard): Earthrise. Take a look now.
200 41 37 Duke: [Young in Tech transcript] Houston, another great view that we had right before TEI was your - your prime Earthset. Your crescent was - your - the lit - light crescent of the Earth was tangent to the lunar horizon. And, as you went down, you ended up looking like a ...
200 41 55 Mattingly (onboard): I bet you'd like [garble].
200 41 56 Duke: ... big bull horns up there.
200 41 59 Young (onboard): Look at all those swirls.
200 42 02 Mattingly (onboard): Yeah, why don't you get some of those? I -
200 42 01 Peterson: Roger. 16, let's go High Gain, Auto.
200 42 05 Duke (onboard): I have made it.
200 42 06 Young: Thanks.
200 42 11 Mattingly (onboard): High Gain to Auto.
200 42 15 Young: You have it.
200 42 16 Young (onboard): I don't think that thing's gonna work. It's beeping.
200 42 17 Peterson: Thank you.
Public Affairs Officer: And Apollo 16 just passed through 700 nautical miles.
200 42 22 Mattingly (onboard): That's the antenna. Well, increasing rate. Isn't it?
200 42 27 Young (onboard): It's like a billiard ball. That's what people can't understand, how flat and round it -
200 42 34 Duke: And my TSB has got a red stripe on it. Will you put some water on it and - and throw it across, please? Just -
200 44 09 Young: Houston, we now have, looking out the center hatch window, the whole - the - the Moon fills the whole window. I can see from horizon to horizon by just being about four inches from the center hatch window. What a spectacular view.
200 44 23 Peterson: Roger.
200 44 28 Young: That's from horizon to horizon along the equator. And we are really climbing away from the planet. You can just see it getting smaller by the second.
200 44 39 Peterson: You're really moving out, huh?
200 44 45 Young: Yeah. We're - doing just like old 97, really really moving down the track.
200 44 52 Peterson: Roger.
200 44 57 Mattingly: Almost as fast as John was driving that Rover yesterday.
200 h4 58 Peterson: Roger.
200 48 15 Duke: Pete, out of Window 5, I can already see the whole sphere.
200 48 23 Peterson: Roger.
200 50 15 Mattingly: I just can't get these new guys away from the windows.
200 50 16 Peterson: Roger.
200 50 23 Young: That view is just beautiful.
200 50 50 Peterson: And, 16, we're showing the Image Motion, On, and we'd like you to go Off, if it is On.
200 51 03 Mattingly: Okay. That's in work.
200 51 05 Peterson: Roger.
200 51 35 Mattingly: Don, I'll have to stop the camera and start it again. Is that okay?
200 51 40 Peterson: We concur, 16.
200 52 41 Mattingly: Okay, Don. I've got the camera running again. What barber pole setting did you want on the - on the speed?
200 52 52 Peterson: Barber pole plus 2, 16.
200 53 13 Mattingly: Okay. You've got it now. Is there anything else we have out of configuration?
200 53 17 Peterson: I think not, but stand by a minute.
200 53 41 Mattingly: You know, you can sort of sense a - From where we're looking right now, you can sense a swingout in this big arc back toward the Earth. I'm looking right now at my 12 o'clock out the hatch window. Seems like we're almost climbing right away from the center of the Moon. And I can see the whole - Mare Crisium is spread out up to the north, and on our groundtrack, well, just north of our groundtrack, you can see Messier A and B Craters and Langrenus.
200 54 30 Peterson: 16, we can go ahead and get the Gamma Ray deployed to eight feet. That's 59 seconds.
200 54 40 Mattingly: Okay. I'll do that. Eight feet to 59 seconds. And this is the one place we can get a good view of Humboldt that we got on our first pass there.
200 54 57 Peterson: Roger.
200 55 17 Mattingly: Okay. Don. You want those deployed for 59 seconds. Is that affirmative?
200 55 20 Peterson: Roger.
200 55 30 Mattingly: I guess in SIM bay attitude, the only thing we have been able to see so far is Sea of Kovalsky, and Charlie said he got a view of it out his window. So I guess we've - just about now we're able to see the whole Moon. Boy, we're really moving away fast.
200 55 50 Peterson: Roger.
200 55 53 Mattingly: That's the whole Moon out - out a window. Back from it about two inches.
Public Affairs Officer: Apollo 16 is now some 1,400 nautical miles from the Moon.
200 56 25 Mattingly: Okay. The Gamma Ray is out.
200 56 30 Peterson: Roger.
Public Affairs Officer: And here in the Control Center, the Flight Dynamics Officer just confirmed John Young's reports from on board the spacecraft that that burn was almost precisely as planned. With a very small midcourse correction requirement showing at this time.
200 56 55 Mattingly: From this distance, the color is very much the same as it was when we were orbiting it. And that is that no three men on any one crew can agree on what the color really is.
200 57 10 Peterson: Roger.
200 57 l4 Duke: Looks like to me, Pete, that the mare right now just picked up a bluish-black cast to them.
200 57 21 Young: Charlie, these maria are brownish-black casts.
200 57 24 Duke: John says brownish.
200 57 27 Peterson: Roger. Understand a bluish-brownish black cast. You guys have invented a new one this time, anyway.
200 57 33 Duke: That's right. We'll get Ken's opinion. Standby.
200 59 59 Duke: Pete, did CST come back with anything on those wrist rings?
201 00 06 Peterson: Stand by one, Charlie. We'll check on it.
201 00 32 Young: You know, as we move out from the Moon, I think that by looking at the varied structures on the surface, that we can see from here, I guess my impression of it is that the Moon may be 4 billion years old plus, but it sure had a - and it may eventually have stopped growing after the first 500 million or changing dynamically, like the Earth changes, but during that first 500 million years, it was certainly busy cause it really has a lot of variety down there, and we haven't even begun to scratch the surface of com - complexity of the story. That's my personal opinion.
201 0l 20 Peterson: Roger. Charlie, on the problem with the rings, I guess we don't really have an answer for you, and we may get some more in the morning. But there's no apparent good way to do anything about that. We don't have a cleansing agent or a lubricant that we can use on them. I guess you'll just have to use more force on them.
201 0l 45 Duke: Fine. With - we can get them locked with a little force, and they pass checks okay, once we get them on.
201 01 53 Peterson: Roger.
Public Affairs Officer: The ring that Charlie Duke was asking about is the glove lock ring. The problem that he described is in getting the gloves locked onto the suit and you heard him say that it does take some force to do it, but once they get it done, and get the gloves locked in place they're maintaining a good seal and the suit is passing suit integrity check alright. The recommendation, from Capcom Don Peterson, was that there is little we can do about cleaning the grit out of those wrist locks. They looked into the possibility of perhaps pouring water into them but they felt that that would only turn the dirt that's in there to mud and would really not improve the situation any. So the crew was advised to leave them as they are and apply the necessary force to get them locked. It appears that this will cause no problem. Apollo 16 at the moment is 1,766 nautical miles from the Moon continuing to climb out rapidly, although the velocity is dropping off, down now to 60,245 feet per second. And about 12 hours from now or at 212:53:36 seconds the spacecraft will again cross that mythical line we call the Lunar sphere of influence. At that point they will be under the dominant effect of Earth's gravity. We'll have our displays switched over from Moon reference to Earth reference and we'll begin seeing Apollo 16 accelerating toward Earth.
201 04 19 Peterson: And, 16, I've got a couple of Flight Plan changes for you at 201:30 [201:18] and 201:35 [201:22].
201 04 32 Mattingly: Okay. Wait a second.
201 04 35 Peterson: Roger.
201 04 37 Mattingly: Can you stand by just a second on those.
201 04 39 Peterson: Sure can. Just call me before you do the Verb 49. We've got some attitude changes.
201 04 51 Mattingly: Okay. We won't go anywhere.
201 06 43 Peterson: Okay, 16. The Verb 49 at about 201:07 [200:55] in the Flight Plan, for the UV photography, should have been started, oh, about 10 minutes ago.
201 06 57 Mattingly: Okay. We'll go to it now.
201 07 00 Peterson: Roger. And it's correct as you have it now.
201 07 43 Mattingly: Okay, Don. This is the 174, 212, and 64, right?
201 07 47 Peterson: That's affirmative.
201 08 08 Peterson: And, 16, we've got a REFSMMAT, if you're ready to Accept?
201 08 20 Young: Roger. Stand by on that for a second.
201 08 23 Peterson: Roger.
201 10 40 Peterson: And, 16, if you can copy, I've got this Flight Plan update; I guess we need to go ahead and get it in.
201 10 48 Mattingly: Okay, Don. Give me 30 seconds.
201 10 49 Peterson: Roger.
201 12 42 Mattingly: Okay, Don. Go ahead with your updates.
201 12 47 Peterson: Okay. I've got this Verb 49 maneuver that's at 201:30 [201:18]. We want to change that from a maneuver to thermal attitude to a ramu - maneuver to Sco X-1 attitude. And the angle - the new angles are at 347, 071, 000, and the High Gain is minus 36, and Yaw is 176. And we also want to add Alpha Particle/X-Ray Cover, Open, at that point.
201 13 38 Mattingly: Okay. And we've got a Verb 49 maneuver to Sco X-1 and the attitude is 347, 071, and 000. The High Gain is minus 36 and 176, and we'll open the Alpha/X-Ray Cover.
201 13 52 Peterson: Roger. And at 202:25 [202:13] -
201 14 02 Mattingly: Okay. Just a second, I had - we hadn't updated our time this far. Well, we're going to get a clock sync here when we ...
201 14 08 Peterson: Okay, Ken. I wouldn't bother updating the time very much further because you're going to do a clock resync here at 202:20 [202:08].
201 14 22 Mattingly: Okay. Well, I stopped an hour too soon.
201 l4 34 Peterson: Ken, all you really need to do is, in the old ...
201 14 36 Mattingly: All right sir.
201 14 37 Peterson: ... going by the old numbers where it was 224:18 or so, which is now about 202:25 [202:13]or so, we want to delete that Verb 49 maneuver. And at 202:25 [202:13] or thereabouts, we will resync the clocks, and that'll bring you up - the clock'll come 226:30, so we'll pick up with the nominal Flight Plan, which will have you going to bed a couple hours earlier tonight.
201 15 10 Mattingly: Okay. Very good. Thank you, sir. Okay, and then what do we do about this - can we do our PTC REFSMMAT change at the same time we're in this attitude?
201 15 27 Peterson: Say again?
201 15 31 Mattingly: Can we do our PTC REFSMMAT change while we're in this Sco X attitude?
201 15 42 Peterson: Oh, I'll have to advise you, Ken. Stand by a minute.
201 15 57 Mattingly: No, sir. I'm timing it.
201 16 00 Peterson: 16, you can go ahead with the maneuver. You'll have about a 68-degree gimbal angle.
201 16 11 Mattingly: Say again.
201 16 17 Peterson: And, 16, we need to up-link a REFSMMAT to you before you get into the P52.
201 16 25 Mattingly: Roger. You have the up-link now.
201 16 29 Peterson: Okay.
201 16 30 Mattingly: I guess the question - I'm not sure if we got the right question and answer together. Can we do the PTC REFSMMAT platform change in the Sco X-1 attitude? Maybe that's the question you answered, I'm not sure.
201 16 56 Peterson: 16, the answer to that apparently is yes, but you will wind up with a 68-degree gimbal angle.
201 17 05 Mattingly: Okay. Did you plan for us to do it some other time? Or -
201 17 25 Peterson: Oh, 16, if the 68-degree middle gimbal angle is acceptable to you, we would like for you to go ahead and press on with it.
201 17 33 Mattingly: Okay. We'll do that, and that'll get us back on time. And we're looking at a 64-degree angle now, so 4 more isn't going to be that different.
201 17 44 Peterson: Roger.
201 18 57 Peterson: And, 16, we're finished with the up-link.
201 19 03 Mattingly: Roger.
Public Affairs Officer: This is Apollo Control at 201 hours, 33 minutes [202:21]. Apollo 16 now 2,735 nautical miles from the Moon. The velocity [has fallen] to 5,782 feet per second and it's continuing to drop slowly.
201 21 47 Peterson: Ken, we want the Pan Camera to Standby and you can deploy the Gamma Ray boom the rest of the way out.
201 21 51 Mattingly: Okay, Pan Camera to Standby and we'll deploy the Gamma Ray.
201 22 36 Mattingly: Okay. The Gamma Ray's going out.
201 22 38 Peterson: Roger.
201 24 09 Peterson: Okay, 16. Go Pan Camera, Power Off.
201 24 l4 Mattingly: Okay. Pan Camera Power's coming Off.
201 25 47 Peterson: And 16, there's an advisory - when you do it - going to the P52. You'll probably get a 401 alarm, which means that you've exceeded 60 degrees middle gimbal angle. You can go on with it, anyway.
201 25 58 Mattingly: Okay.
201 26 20 Mattingly: Okay.
201 32 25 Peterson: 16, Houston. We've got some words on the LiOH canister any time you're ready to listen.
201 32 43 Duke: Stand by one, Pete. Ken's eyeballing it.
201 32 46 Peterson: Roger. There's no hurry.
201 34 09 Peterson: 16, did you call?
201 34 14 Mattingly: No, sir. Be with you in a minute.
201 34 15 Peterson: Okay.
201 34 56 Mattingly: Okay, Don; go ahead.
201 34 58 Peterson: Okay, on the LiOH canister, the words we got on it are that we'd never had one of those straps break on a flight unit. However, apparently if you put more than 128 pounds of force on them you - you can break them. And what we'd like you to do now is go ahead and change - make that change so that we don't miss it when we do the clock sync. I believe it's listed at ...
201 35 26 Mattingly: Now, Pete, that's some good thinking. Yes, sir; I've got it at 202:20.
201 35 32 Peterson: Roger. And we were afraid we'd get the clock ...
201 35 34 Mattingly: ... get that out of the way.
201 35 35 Peterson: Okay.
201 35 40 Mattingly: Say again, Don.
201 35 41 Peterson: I'm just saying it's up close to the time we're gonna sync the clocks. We're afraid we might omit it.
201 35 50 Mattingly: Yep, that's good thinking. Okay; while we're changing that out, if you want to - you want to do your thing with the computer, or do you want us to do the P52 first?
201 36 06 Peterson: Stand by one.
201 36 30 Peterson: Ken, you talking about the clock sync?
201 36 36 Mattingly: Yes, sir.
201 36 38 Peterson: Okay, I guess we'd like you to do the P52 first.
201 36 43 Mattingly: Okay. We'll get on with that in just a minute as soon as we get the [garble] changed here.
201 36 55 Duke: Hey, Pete, y'all got any ideas why old Orion didn't hold attitude jettisoned?
201 37 03 Peterson: I guess I don't have a complete briefing on it. We've got a couple of suspect conditions. I'll try to get back to you later.
201 37 13 Duke: Okay. No hurry on that one.
201 37 15 Peterson: Roger.
201 37 33 Mattingly: Hey, Don, in order to keep our lithium things from driving us buggy on the way home with the time change, we're just going to go ahead and exchange the canisters as they're called out in the Flight Plan here. And we'll just be skipping the couple that'll be unused. Okay?
201 37 48 Peterson: Okay. That sounds good, Ken.
201 42 17 Duke: Hey, Pete, is Tony coming on tonight?
201 42 18 Peterson: That's affirmative. About midnight, I guess. About 2 hours and 15, 20 minutes from now.
201 42 29 Duke: I guess that's after - after we go to bed?
201 42 31 Peterson: I believe that's right, Charlie.
201 51 20 Peterson: Good, 16. We copy the torquing angles. They look real good.
201 51 30 Mattingly: Okay. That was at time 202:03:00.
201 51 34 Peterson: 202:03:00. Roger.
201 52 16 Mattingly: Don, how long we gonna be in this attitude?
201 52 19 Peterson: Stand by one. About 30 or 40 more minutes, 16.
201 52 33 Mattingly: Okay, thank you.
202 02 48 Mattingly: Okay, Houston. Would you like to take over our clock?
202 02 53 Peterson: Stand by. We're just about ready to do that.
Public Affairs Officer: This is Apollo Control at 202 hours, 14 minutes [202:02]. We're preparing to update the clocks in the Control Center and aboard Apollo 16. You heard Capcom Don Peterson a short while ago discuss this with the crew. And the clock update will amount to 24 minutes, 34 seconds - or 34 minutes - We'll try that again - 24 hours, 34 minutes, 12 seconds and at 202 hours, 30 minutes [202:18], or about 16 minutes from now that update will be entered into the clocks here in the Control Center and also into the clocks aboard the spacecraft. Faced with the problem with correcting flight plans all the way to - Here's a call from the crew - we'll pick that up.
202 04 52 Peterson: Okay, 16; if you'll go Accept, we'll uplink this clock sync. And while they're doing that, I'll tell you kind of what's going to happen. But - We're going to do it. The total change will be 24 hours 34 minutes and 12 seconds. And what we would like you to do is on, let's see here, Page 338 in the Flight Plan, we'd like you to pick up at about 226:30 in the Flight Plan ...
202 05 22 Mattingly: Hey, Don, (laughter) I'm sorry you're gonna - Hey, Don, you're gonna have to start over again. Just as you started talking, our cabin fan let out a great big moan, and so we turned it off then, after all sitting up straight to see what it was. So would you start over again?
202 05 41 Peterson: Okay, I'll do that. If you'll go Accept, we've got the clock sync ready to go, and it'll be a 24 hour 34 minute and 12 second total change in the clocks. And what we would like you to do is pick up the Flight Plan at the old - at the old point of 226:30, actually pick up those events, although your clock may not come out exactly on that time. And what we're saying is we may cut a little bit into your rest period.
202 06 12 Mattingly: Okay; but we're planning to do a little stowage here that we never have had a chance to get done.
202 06 19 Peterson: Roger.
202 06 20 Mattingly: So we're going to have to do some of that stuff now.
202 06 23 Peterson: Okay. The items we'll pick up with, I guess, are the ones immediately following 226:30 [201:55]in the old Flight Plan.
202 06 35 Mattingly: Okay.
202 07 17 Peterson: Okay. Ken, your clock should be changed now. And if you'll pick up with - on Page 338 where it says, "Gamma Ray, Shield Off," you can go ahead and finish that stuff up.
202 07 29 Mattingly: Okay. I take it we're gonna hold off on this PTC for a while until you've had enough time in this attitude?
202 07 40 Peterson: Stand by one.
202 07 53 Peterson: Roger. We'd like to stay away from the PTC for about 15 more minutes.
202 08 00 Mattingly: Okay; we'll do that.
202 09 32 Peterson: Okay, 16. We'd like you to close the Alpha Particle/X-Ray Cover now, but we want to leave the X-Ray on for an extra 30 minutes because we failed to get some calibration data, and I'll call you when it should go off.
202 l0 52 Peterson: 16, did you copy on the Alpha Particle/X-Ray Cover?
202 11 03 Duke: Roger.
202 11 05 Peterson: Okay. We want to get that closed and leave the X-Ray on, and I'll call you when it should go off. About a half hour from now.
202 11 15 Duke: Okay, I closed the cover.
202 11 19 Peterson: Okay. And, also, we'd like you to read out Tephem for us. That's Verb 5 Noun 1 1706 Enter.
202 11 51 Young: How's that look to you, Houston?
202 11 54 Peterson: Stand by one; we'll take a look at it.
202 12 01 Peterson: Okay, 16. That looks good.
202 12 04 Young: That's three balls 11, okay.
202 13 03 Peterson: Okay, 16. On those numbers you've got on the DSKY there, if you'll go to the G&N Checklist, Page 9-4, you can load Register 2 and 3 in column Bravo, Lines 4 and 5.
202 13 26 Duke: Okay, G&N Checklist, 9-4, what - load what?
202 13 30 Peterson: Load Register 2 and 3 in column Bravo, line 4 and 5.
202 13 47 Duke: Okay.
Public Affairs Officer: This is Apollo Control. We have now completed the clock sync and update, synchronizing the clock aboard the spacecraft and the clocks here in Mission Control with an updated time, advancing them 24 hours, 34 minutes [and] 12 seconds. Faced with the choice of making the Flight Plan agree with reality would require updating events item by item to account for the difference in time introduced when the LM landing was delayed and the subsequent early departure for Earth, or making reality in effect agree with the Flight Plan we've chosen to do the later. Which means that we moved the clocks ahead 24 hours, 34 minutes and 12 seconds. And having completed that we're in effect back on the normal Flight Plan. At present time our clock reads 227 hours, 11 minutes 20 seconds . And at this point in the Flight Plan the crew will be preparing for their rest period. We've asked them to go back and pick up items about 30 minutes prior to that. Which includes putting the spacecraft in the Passive Thermal Control mode, rotating it about its longitudinal axis at the rate of 3 revolutions per hour to maintain the proper temperature equilibrium. Completing that they'll then begin their pre-sleep checklist and probably begin the rest period around 227:30 [202:44] although we expect that they will be a little late getting to this. And will begin the sleep period probably 30 to 45 minutes after that. That's somewhere around 228 to 228:30. In making this clock update it should now eliminate the need for most of the Flight Plan updates that we have been forced to make for the last several days. The clocks now agree with where we should be in the Flight Plan. An arbitrary change keeps all of the sequences as they should be and the intervals between the events where they should be. And we'll also have another clock with a nomenclature TV 5, which would be viewable on the - on the monitors in the news center, which is counting the actual ground elapsed time. Which is 202 hours, 17 minutes. But [the] time that is in sequence with the Flight Plan is the updated time, which now reads 227 hours 3 minutes. This time by the way, is arrived at by taking the Flight Plan time for Entry Interface and subtracting the predicted Entry Interface time, using the original or the older GET, the previous GET before we updated, then subtracting the Entry Interface time that we would have with our previous GET or Ground Elapsed Time, from the Entry Interface time that is showing on the Flight Plan. Now we come up with the difference in time, which is taken care of in the clock update of 24 hours, 34 minutes and 12 seconds. This then is the time that is used for the clock update. And as mentioned previously, we are now more or less back on the nominal Flight Plan. Now there would be several minor changes, but nothing like the number of changes that we have been experiencing for the last several days.
[Break in Communications for 30 minutes.]
202 44 21 Young: Houston, Apollo 16; over.
202 44 23 Peterson: Go ahead, 16.
202 44 28 Young: Roger. We're gonna go ahead and service the accumulator to - to 55 percent if that - that's all right with y'all.
202 44 38 Peterson: Stand by one. Okay, you can go ahead with that, John.
202 44 46 Young: Trying to - okay, we're trying to get as many of these nitpickies out of the way for this EVA tomorrow.
202 44 52 Peterson: Okay, and in connection with that, the surgeon advises that the CMP will need a new hiomed harness prior to the EVA. We do not have any requirement to monitor the CMP tonight. We would like to monitor either you or Charlie.
202 45 18 Young: Roger.
202 45 58 Young: Okay; we decided you can look at me tonight.
202 46 01 Peterson: Okay, John.
202 46 09 Young: I'll put on a biomed tonight, but I've got a bunch of things to do before - before I can get to it. Okay?
202 46 15 Peterson: Okay, sir.
202 51 12 Duke: Pete, looking out of the hatch window towards the -back at the Moon, I think this view's even getting more stunning, and - just brilliant whites and grays against a stark black background - looks like it's not even real.
202 51 30 Peterson: Roger.
Public Affairs Officer: That was Charlie Duke giving us a visual description of the Moon from a distance of 7200 nautical miles. We are working on some Central Standard Time conversion figures which we'll pass along to you shortly. We'd like to get those checked and verified by the Flight Activities Officer. We hope that will assist in the process of converting the updated GET time to a Central Standard Time.
202 52 39 Duke: Hey, Pete, how far out from the Moon are we now?
202 52 44 Peterson: How far out from the Moon?
202 52 48 Duke: Yeah.
202 52 49 Peterson: Stand by a minute.
202 53 00 Peterson: Charlie, you're 7294 miles out.
202 53 05 Duke: Thank you.
202 53 58 Duke: Hey, Pete, we'd like to send you a picture of this if y'all got - can take the - the TV. This is really a spectacular sight.
202 54 15 Peterson: Okay; stand by, Charlie. We'll see what we can do.
Public Affairs Officer: That was Charlie Duke telling us he'd like to send us some TV. Our network controller is - says we're working that right now. The primary problem, of course, is to get the necessary ground lines up -
202 54 38 Peterson: Charlie, while we're working that, can you copy about four short items into the Flight Plan at 226:40?
202 54 44 Duke: Yeah, wait a minute.
Public Affairs Officer: And network says we just happen to have lines coming up for television that we were planning to receive from the Lunar Communications Relay Unit on the Moon's surface. So we hope that if we can get things in configuration, we'll attempt to get a television picture from the Command Module of the lunar surface.
202 55 00 Peterson: Charlie, you can go ahead and start getting that camera out. We'll work up the lines here.
202 55 06 Duke: Okay.
202 55 15 Young: Okay, 226:40 [201:53]; go ahead.
202 55 20 Peterson: Okay; at 226:40 [201:53], we want to Retract Mapping Camera, Close the door, put the Mapping Camera to Standby, put the X-Ray to Standby, and then pick up at 226:50 there in the Flight Plan.
202 55 58 Duke: Okay [garble].
202 57 15 Duke: Pete, did y'all copy that?
202 57 17 Peterson: Negative. I guess we lost comm there temporarily, Say again, Charlie.
202 57 21 Duke: Okay; you gave us a Flight Plan update for 226, and our clocks now say 227 ...
202 57 29 Peterson: That's affirmative.
202 57 30 Duke: ... 23.
202 57 31 Peterson: We're going to have to go back to 226. It's just prior to where you go into PTC and pick up these four items, and then get into PTC.
202 57 41 Duke: Well, why don't you give us a call when you want us to do those, since we don't know when 226 is.
202 57 46 Peterson: Okay.
202 57 53 Young: Is 226 right now, there, Pete?
202 57 58 Peterson: Say again?
202 58 02 Young: 226 is supposed to be right now?
202 58 05 Peterson: Negative, negative. Right now we're showing 227:44:07, 8, 9.
202 58 16 Young: Okay, but I mean you're saying what - When do you want us to do those items at 226?
202 58 21 Peterson: We'll call you when we want you to start in. That's just where we want you. That's the items we want done and then I'll tell you when to start them.
202 58 33 Young: Okay.
202 58 36 Peterson: Okay, 16; I'm - 16; I've been advised it really doesn't matter when you do them, as long as we get them all done before you go to sleep.
202 58 47 Young: Okay.
202 59 20 Young: Houston, you're saying we can - we're now cleared to take the Gamma Ray, Shield Off, the X-Ray to Standby, the Alpha/X-Ray Cover to Close, and so forth, right?
202 59 32 Peterson: That's affirmative.
Public Affairs Officer: This is Apollo Control. We're standing by now to receive television from the Command Module. Again to reiterate the situation as far as the TV goes. Charlie Duke reported being very impressed with the view of the Lunar surface from an altitude of some 7,000 nautical miles, [and] requested that we get things set up on the ground to receive TV. Fortunately we were in fact set to do that but not from the Command Module. We were planning to turn on the camera aboard the [Lunar] Rover on the lunar surface at 11 pm Central Standard Time. Consequently, the lines between Goldstone, which is the Manned Spaceflight Network station on which we were to receive the television from the Lunar surface - those lines were up and we were ready to go when we got the word from Charlie Duke that he was planning to turn on the television camera. So, we should be in good shape to receive a color picture from the Command Module of the Lunar surface. The plan as far as the television that we were going to get from the Rover is simply to delay that until the crew has completed the television transmission that their planning and then to pick up television from the Lunar surface. At the present time Apollo 16 is 7,697 nautical miles from the Moon travelling at a speed of 4,951 feet per second, and we're standing by for [a] television picture. Flight Director Pete Frank estimates that it would take the crew about five minutes to get the camera out and in operation.
203 02 27 Duke: Pete, could we take the S-Band Aux switch out of SCI to get the - monitor set up?
203 02 35 Peterson: Stand by one.
203 03 11 Peterson: Okay, 16. We need to get the Mapping Camera, Off - Stand by. Get the Mapping Camera to Standby, and the Gamma Ray, shield on, prior to going out of the SCI position.
203 03 30 Duke: Okay. The camera has retracted. We're gonna go to Off on the Mapping Camera, and the gam - and the shield is on.
203 03 39 Peterson: 16, want the Mapping Camera to Standby, and the Gamma Ray, shield on.
203 03 45 Duke: Okay. Yeah; okay.
203 04 00 Duke: Okay. Can we go to TV?
203 04 03 Peterson: Affirm. You can go to TV.
203 04 39 Mattingly: Okay. I'm gonna have to hit a Command Reset. Is that all right with Super Tech - Comm?
203 04 45 Peterson: Stand by one. That's affirmative. Go ahead.
203 04 56 Duke: Okay.
Public Affairs Officer: This is Apollo Control. Our Network Controller reports that we're seeing sync and it looks like the camera is coming up. We don't yet have a picture, but we should have that shortly. And we've [now] got a black and white picture. That should be through the converter.
203 08 12 Duke: Okay, Houston. You should have a picture coming now.
203 08 16 Peterson: Roger.
203 08 56 Young: Does that look like the Moon to you, Houston?
203 09 03 Peterson: Not yet, I guess.
Public Affairs Officer: We suspect Charlie Duke is the camera operator, and that view a moment ago was John Young.
203 09 52 Peterson: Charlie, we'd like you to verify that you've got that camera pointed at the right one this time.
203 10 00 Duke: I happen to be not pointing those cameras this time.
203 l0 04 Young: They don't let - We don't let Charlie make that choice any more; Ken's doing that kind of work now.
203 10 09 Peterson: Roger. Understand. It's a beautiful picture, Charlie.
203 10 18 Young: I tell you - yeah. And it's just about that big, too, from where we're looking. It just - just fills the window just about like that.
203 10 29 Peterson: That's really a great looking -
203 10 30 Young: Are y'all getting it real time?
203 10 33 Peterson: Affirmative. We just happened to have the lines up for au LCRU picture, so we're getting it real time.
203 10 47 Duke: Ah, great.
203 10 48 Young: Is the LCRU still working?
203 10 53 Peterson: It was last night, they say.
203 10 57 Young: I'll be darned. Did they watch lift-off and everything?
203 11 05 Peterson: Affirmative. Had a beautiful lift-off. Got to watch all of it almost.
203 11 11 Duke: How much did you see, Pete?
203 11 24 Peterson: We got to see about the first 30 or 40 seconds of it real good.
203 11 32 Duke: Hey, great! That's wonderful.
203 11 37 Peterson: That was something. I guess we'll have to tell you that was spectacular, because you didn't get as good a view of that as we did, I guess.
203 11 45 Duke: Man, I tell you. That ascent engine coming on, you - you - it was a real - It wasn't what I expected, anyway. At ignition, there, it seems like it sort of sits a little bit, then it grabs you and, boy, off you go! And it takes you a while - at least, it did for me - to get my eyeballs uncaged. And we were - then all I saw out the window was the MESA blanket; then we were back on the gages.
203 12 15 Peterson: Roger. It looked like you lifted out of there pretty rapidly.
203 12 21 Young: Yeah; that machine just flies so nice. It's just unbelievable! But once you get to ascent stage, it's really light and responsive. Boy, you fire one of those thrusters and it does exactly what you want it to.
203 12 36 Peterson: Roger.
203 12 45 Duke: And this is what you look like after 4 days with no shaving.
203 12 51 Peterson: Roger.
203 13 05 Young: And we refuse to show you the pressure suits.
203 13 10 Peterson: Roger.
203 13 11 Young: You can tell Charlie's real adapted to zero gravity. A couple of days ago, he couldn't spin that pencil.
203 13 20 Peterson: (Laughter)
203 13 30 Duke: It takes us country boys a little while to adapt to things, Pete.
203 13 34 Peterson: Right. I'm with you, Charlie.
203 14 07 Duke: You know, Pete, if you took this view that y'all just saw of the Moon and put in a movie, everybody would say you're faking it. It doesn't look like that. And it's just - you can't see any stars, just pure blackness, and that white-gray body sitting out there is really -
[Short segment of CM transcript until 203:23:38.]
203 14 43 Duke: This is what the well-dressed LMP on Apollo 16 has been wearing for the last - well, ever - all the way out and all the way back.
203 15 05 Duke: If y'all get tired of looking, you can just cut off the lines or go to Command Reset or something.
203 15 11 Peterson: Roger.
203 15 22 Duke: One final shot of the beautiful Moon.
203 15 26 Peterson: Roger.
203 15 40 Peterson: Say, Charlie, why don't you try to give us a close-up of each guy, and maybe we can get a playback for the wives tomorrow.
203 15 49 Duke: Okay; we'll do that.
Public Affairs Officer: That view of the Moon came to us from about 8,400 nautical miles above the Lunar surface.
203 15 54 Young (onboard): You want - you want [garble].
203 16 06 Duke (onboard): I think if we get in the LEB [garble].
203 16 08 Mattingly (onboard): [Garble] always work [garble].
203 16 17 Young (onboard): That ain't [garble].
203 16 17 Duke: Okay; we got it off. We'll turn - bring it up in just a second.
203 16 21 Peterson: Roger.
203 16 42 Mattingly (onboard): All right, you guys [garble].
203 16 59 Duke (onboard): (Laughter) [Garble.] Boy, you know, I think this is [garble] picture.
203 17 07 Young (onboard): Huh?
203 17 09 Duke (onboard): Huh?
203 17 22 Mattingly (onboard): [Garble].
203 17 24 Duke (onboard): I know it. (Laughter)
203 17 25 Young (onboard): [Garble] like that, you could go all over the country.
203 17 30 Duke (onboard): [Garble] Flight Plan right in front of you.
203 17 31 Mattingly (onboard): Yeah, [garble].
203 17 32 Duke (onboard): Are you?
203 17 34 Mattingly (onboard): Huh? Yeah, I'm trying [garble] (laughter).
203 17 36 Young (onboard): Oh, yeah. Don't want to waste any time.
203 17 45 Duke: This is the relaxing attitude for the world - for the seasoned space traveller.
203 18 01 Duke: Boy, I can hardly believe the last 3 days, Pete. That was - The Cayley Plains is really the most fascinating place I've ever been in my life and will ever hope to go, and we sure had a good time collecting all the rocks.
203 18 19 Peterson: Roger.
203 18 26 Young: Shift.
203 18 27 Duke: Ken. I'll let you look at somebody else now.
203 18 31 Peterson: Charlie, everybody else is doing a mental interpolation. The Surgeon's standing on his head.
203 18 40 Duke: You say - what - what was that?
203 18 46 Mattingly (onboard): [Garble].
203 18 50 Young (onboard): (Laughter) Okay.
203 18 43 Peterson: I said everybody in the MOCR is doing a mental interpolation except the Surgeon, and he's standing on his head.
203 18 50 Duke: (Laughter) Okay. That's great.
203 18 59 Young (onboard): (Laughter)
203 19 04 Mattingly (onboard): Hey, tell him ...
203 19 07 Duke: Okay; Ken just turned the camera over, you can have him turn the other way now.
203 19 14 Peterson: Roger. (Laughter) I'll have him ...
203 19 16 Duke: But then the rest of you will stand on your heads.
203 19 41 Young: Okay; I don't know if you can see this or not. See this dirty hand?
203 19 46 Peterson: Oh yeah, we can see that.
203 19 47 Young: See that? Cam you see the dirt under those fingernails - can you see the dirt under those fingernails?
203 19 52 Peterson: Roger.
203 19 53 Young: That's Moon dust. You talk about a - you talk about two dirty human beings. It took 10 minutes before we could get Ken to open the door. As soon as he saw us, he wanted to close it.
203 20 09 Peterson: Roger. We understand. He runs a neat ship.
203 20 12 Young: And we're still that way. Yeah, wait'll you see some of these rocks. And we've - and some of the data that Ken's got. That's really something. The Moon around Alphonsus. I got a chance to look at it today for the first time, and - it's really - it's really a strange place. How's everybody doing down there at MCC. Is everybody starting to take it easy for a change?
203 20 45 Peterson: Oh, I think we're all breathing easy now. And if we can, we'd like to get a quick look at the CMP because we're going to have to give up the lines here in a couple of minutes.
203 20 55 Duke: Okay. Will do.
203 21 08 Young (onboard):Excuse me, Ken.
203 21 08 Peterson: The only - the only really neat guy on the crew.
203 21 14 Duke (onboard): Huh? [Garble].
203 21 16 Young (onboard): [Garble].
203 21 21 Duke: What'd you say? You must be blind.
203 21 27 Young: He does dress pretty well.
203 21 30 Duke: Notice the reflection off the bald head?
203 21 42 Duke: Did the Surgeon do a back flip on that one?
203 21 46 Peterson: Negative. He's not agile enough.
203 21 57 Duke: Ken doesn't look like he is either.
203 22 02 Young: (Laughter) I told you, in a J-mission spacecraft, you - you either have to be a midget to do that, or have thought about it a lot before you try it.
203 22 17 Duke: Okay. We're going to sign off here.
203 22 17 Duke (onboard): Here comes the lens cover.
203 22 25 Peterson: Okay. Thanks a bunch, guys. We'll being talking to you again in a minute.
203 22 31 Duke: Okay. Thanks, Pete. We'll go back to SCI on the S-Band Aux.
203 22 43 Peterson: Okay. And for thermal reasons, as soon as you can, we'd like to go on now and get into PTC.
203 22 50 Duke: All right. We'll start up.
203 22 52 Young: We're for that.
203 22 57 Duke (onboard): [Garble], Ken.
203 22 58 Young (onboard): Let me move out of here, T.K. Okay. What'd you have?
203 23 06 Duke: What's happening down in there?
203 23 11 Peterson: Say again, Charlie.
203 23 17 Duke: Get any newsy items for today?
203 23 22 Peterson: No. I guess we don't have anything going on right now, Charlie. Everything's routine. If you want a news report, we can dig one up, I think.
203 23 37 Duke: No, it's not important. Wondered what - We haven't had an update for a while; y'all must have ran out of paper.
[End of short CM Transcript.]
Public Affairs Officer: This is Apollo Control. That unscheduled TV transmission of the Moon and the interior of the Command Module lasted for about 15 minutes and it showed us the surface of the Moon from about 8,000 nautical miles. Now the crew will shortly be putting the spacecraft into the slow rotation and on its Passive Thermal Control or the Passive Thermal Control mode. And we hope before too much longer they'll be getting ready to begin their rest period.
Public Affairs Officer: This is Apollo Control. We're now getting ready to bring up the camera aboard the rover at Cayley Plain Descartes site. And expect to have the camera in operation for about 30 minutes. We have about 10 minutes acquisition time remaining with the 210 foot dish antenna at Goldstone, California. We'll then be handing over to one of the 85 foot antenna sites for the remainder of the 30 minutes that we expect to get television from the Lunar surface.
203 29 04 Young: How does the midcourse look, Pete?
203 29 10 Peterson: Stand - stand by one.
203 29 28 Peterson: Okay, 16. All we have is the G&N data. We don't have tracking data because you are uncoupled. However, based on the G&N data, it looks like less than one foot per second.
203 29 42 Young: Yeah; but - course, I - Yeah, I forgot us - about us being uncoupled.
203 29 51 Peterson: Doesn't look like anything very big. About a foot per second.
203 29 56 Young: Yeah. Well - I - the G&N - thought it did a good thing.
203 30 01 Peterson: Yeah, we concur. G&N looks great.
Public Affairs Officer: The noise that we are getting on the downlink [from the] spacecraft is due to the handover from the 210 foot dish antenna at Goldstone to the 85 foot dish also at Goldstone. We've now gotten good lock-on and should have good solid communication.
203 32 25 Duke: Houston, 16 on Omni Alfa. Over.
203 32 28 Peterson: Roger, 16. You're loud and clear.
203 32 33 Duke: Okay. We dropped up-link, it looked like, for a while. Signal strength went to zero on all antennas, and I had a Command Reset, and we're Omni Alfa, if that's okay.
203 32 53 Peterson: If you'll go Pitch minus 70 and Yaw 130, we can reacquire on the high gain, 16.
203 33 03 Young: In where?
203 33 04 Duke: Okay.
203 33 45 Duke: Okay. There you are, Pete.
203 33 47 Peterson: Okay. You're loud and clear.
Public Affairs Officer: This is Apollo Control. We're standing by now for the antennas at Goldstone, California which were locked-up on the Command Module.
203 34 27 Peterson: Okay. Charlie, a little while back, you were asking what time Tony was going to come aboard, and he's just walked in here and gotten plugged up if you've got anything for him.
203 34 40 Duke: Okay. Say again.
203 34 42 Peterson: Earlier you were asking what time Tony was going to come in, and he's on board right now.
203 34 50 Duke: Okay.
Public Affairs Officer: As soon as the Goldstone antenna is properly pointed at the Lunar surface we'll be switching over to the Lunar Communications Relay Unit camera.
203 35 07 Young: Hey, Tony, this is John. Over.
203 35 11 England: Yeah. Go ahead, John.
203 35 15 Young: I don't know if we told you or not, but Charlie and I think you really did one whale of a job doing those EVAs. We know how tough that is to do all those real-time changes. We just thought you did one heck of a good job, and we sure appreciate it. Just wanted you to know that.
203 35 34 England: Oh, thank you much. But you guys made it awful easy.
203 35 42 Duke: Hey, Tony. I was sitting here today thinking about those rocks we got, and the thing that really strikes me is that there was - I really don't think we got any volcanic rocks to speak of. Maybe some of those little black clasts were volcanics, but otherwise - I don't think we got any. There wasn't any there. The - there was one other - one other point that could have been - Those ones we were calling shocks could have been a tuff breccia, since they were so friable. But - that we might - that might prove to be the case; but to us, they looked shocked due to the other features that we saw that - that - applied a shocked metamorphism. Over.
203 36 37 England: Right. We - From your description, we had thought there was a good chance that you might have gotten a tuff breccia there. I think, also, the fact that a lot of the breccias were one-rock breccias would in - would mean that you may have your basalts or gabbroic anorthosites or whatever, and that they're just broken up. If they're one-rock breccias or two-rock breccias, it still has most of the information of the - of the rocks we're looking for. It's not like a - you know - if you remember, it's not like a soil breccia, where everything is lost. So we - we're very happy with what you found. Also, did anyone brief you on the newest on the X-ray results ?
203 37 17 Duke: No. Go ahead.
203 37 18 England: Okay. You remember the first look I gave - The first look that I reported to you indicated that the aluminium-to-silicon ratio was sort of intermediate. Well, they've gone back; and with the newer data and a better analysis, it turns out that Descartes has one of the highest ratios on the Moon. The only place we've seen like it right now is on the east side of Smythii. We don't really have a good comparison yet with the east of Crisium. But anyway, it indicates that if any place has anorthosites, you've found them.
203 37 56 Duke: I tell you, Tony, some of those rocks that we picked up - I was leaning, with the color and the crystalline structure that we had - they really gave me the - I didn't want to call it that, but they were certainly crystalline rocks; and there was no question in my mind. They had a sugary texture - the whitish ones. That big - one on the - rim of North Ray, there, with the shatter cone that had - a - a bluish tint to it in the crystalline structure. Although, it might have been just the - an aph - I say crystalline structure, or it might have been an aphanitic matrix; but y'all are gonna sort all of that out when you get bagged ones. I tell you, it really wasn't what we thought - I thought we were going to find up there. I imagined a lot of volcanics; and frankly, if the - if these shocked rocks turn out to be tuff breccias, that will be the only volcanics we found.
203 39 02 England: Right. Understand. I think ...
203 39 04 Young: [Garble].
203 39 05 England: ... the fact that you recovered from the picture we had given you before you went and went ahead and found out what was there and sampled it so well - I think that's - a good indication that the training was good and you guys are really on the ball.
203 39 26 Duke: Well, we tried hard, anyway, Tony; and I think we got every - a piece of every rock that was up there. I really do. They were - and that's, I think, because we were lucky, and the rocks were identifiable.
203 39 46 England: You know, the ...
203 39 47 Duke: [garble]
203 39 48 England: ... difference between a rock being identifiable mad not being identifiable is the level of training. That just says you guys were well trained.
203 39 58 Duke: Well, you guys tried to beat it into us long enough, I'll tell you that. Hope we did a good job.
203 40 08 England: I just got a set of questions that the geology team ...
203 40 11 Duke: ]t looks like ...
203 40 12 England: ... would like to send up to you sometime. Maybe sometime during the Trans-Earth coast, we'll have a chance. I haven't really read through them, so I don't know what they're all about yet.
203 40 26 Duke: Okay. Well, we're gonna go into an eat period and a an EVA prep and try to get some rest before the EVA tomorrow, so - we'll wait on those. Okay?
203 40 34 England: That's fine. Hey, we have the TV back on on the Moon up there, and everything's looking fine. It hasn't changed much since you left.
203 40 47 Duke: Well, we were glad that y'all were able to watch lift-off. We heard that they got about 30 or 40 seconds, which, I think, was neat. It took me about that long to uncase my eyeballs when that ascent engine lifted off.
203 41 01 England: (Laughter) Yeah. Great.
203 41 03 Duke: It certainly wasn't what I thought I was going to - experience.
203 41 09 England: Yeah. INCO was really on the ball. They tracked you right up.
203 41 15 Duke: Well, that's just super.
203 41 21 England: I don't know - We don't know whether Ken understood the up-link while ago on the biomed harness. The idea is that he's going to have to change it before the EVA in the morning. So, if he'll sleep better without one on tonight, he could take the old one off, now.
203 41 40 Young: Okay. We'll tell him.
203 42 23 Duke: And, Tony, the only - on that - on the rocks, back to one other little point, there. That - You know, we called the whitish rocks tuff breccias- I mean, shocked rocks. But we're cou - at least, I'm personally convinced that there are at least two endogenic craters that we passed, and - the big one on the way to North Ray and the big one coming back from - from Stop 8. And so, that might have been a source of a tuff - if that's what they turn out to be.
203 43 03 England: Very good. I just want to emphasize again that ...
203 43 10 Young: [Garble] situation, though.
203 43 12 England: Right. I understand. I just think it was outstanding, maybe serendipity, that we probably - your landing there at Descartes probably sampled the most differentiated place we could find on the front side of the Moon. I think that's really outstanding.
203 43 34 Duke: That's the feeling I got when we started seeing those rocks. That - that basalt that I called under the engine bell there, I think, might end up to be that blackish-bluish rock that we sampled up at North Ray, and so - we'll - but we'll see. We couldn't get any of what I call real basalt in rocks. Maybe some of the clasts will be, though.
203 44 03 England: Okay.
203 44 05 Young: Could you tell from the TV, Tony, how rough that place was? Could you see all those - those swales and valleys that we didn't have mapped on our - that didn't show up on our map that were maybe, some of them, 30, 40, 50 meters deep?
203 44 24 England: Yeah, I sure could. It reminded me of a dune area.
203 44 30 Young: Yeah. That's what it sort of looked like, sort of a dunes plains.
203 44 36 England: Incidentally, somebody here is kind of worried about ...
203 44 39 Young: I'll tell you -
203 44 40 England: ... thermal problems, and we would like to get into PTC as soon as possible..
203 44 45 Young: Okay, as soon as the thing - as soon as the rates get low enough, we will.
203 44 49 England: Okay.
203 44 51 Young: Are the rates good enough now?
203 44 54 England: Negative.
203 45 06 Duke: Tony, that one - that crater at - the endogenic one that we described coming back from North Ray and going out, it - I was guessing 80 meters, John said about 50, but it was really deep; and I'm surprised that we didn't - I sure had no feel for that before we started.
203 45 32 England: Right. Understand.
203 45 44 Duke: I'll tell you one thing, your hair sure doesn't feel very good aft - up here after 3 days with it full of orange juice.
203 45 52 England: I don't know. It may do great things.
203 45 57 Duke: That stuff is great glue, I'll tell you. Boy, we were really worried about those hel - getting those helmets off, but they came - came right on off after we eventually broke the thing and got them cleaned up then.
203 46 11 England: Okay, and on your Flight Plan there, at right about 227:00, for setting up for PTC, I guess your DAP has to be set up for B/D Roll.
203 46 24 Duke: Okay.
203 48 45 Young: Houston, can you give us a holler when these rates get good enough to start PTC?
203 48 50 England: Sure will.
203 50 18 England: Apollo 16, last time you changed the LiOH canister, did you happen to wiggle the other one and see if it had swelled up in there?
203 50 28 Young: No, we sure didn't. That one out of B just came right out.
203 50 32 England: Okay.
203 50 43 England: Okay. Don't worry about it, then.
203 50 52 Young: Okay.
203 52 13 England: Just a brief report from the home fronts here. Everybody's healthy, and happy, and not just little bit proud.
203 52 27 Young: Boy, you had me worried there for a second.
203 52 30 Duke: Thanks, Tony. Appreciate it.
Public Affairs Officer: This is Apollo Control. We're in the process of a shift handover in Mission Control at the present time. Flight Director Jerry Griffin and his team coming on now to replace the Pete Frank team and the spacecraft communicator on this shift, in fact already on duty is astronaut Tony England. We do have an updated time now for the EVA from the Command Module. That is scheduled to occur at the Flight Plan time of 242 hours, 55 minutes, that's our updated Ground Elapsed Time and that would be at 2 hours - rather 2:03 pm Central Standard Time tomorrow. That is the time - the predicted time for the hatch opening for the EVA, again that time is 2:03 pm central standard time. That's a change from the previous time that we had listed of 4:47 pm Central Standard Time. The Flight Plan time again, 242 hours, 55 minutes Ground Elapsed Time. In computing Central Standard Time, from our new updated GET, perhaps the easiest method is to - in the Flight Plan change the time notation at the top of each page which is the hour plus 54 minutes for example, the present GET time is 228 hours 43 minutes at the top of that page in the Flight Plan, which starts with 228, hours 00 minutes above that notation is the Central Standard Time notation of 23:54 or 11:54 [pm]. That time on the top of that particular page would then change to 11:08 [pm] or 23:08 Central Standard Time and that time would follow through the rest of the way through the Flight Plan. At the top of every page, that time updates one hour. The next page would go from 23:54 to 01:54, the way it is currently printed in the Flight Plan. To update that to the present Central Standard Time, it would simply be necessary to change it to 08, change the last two digits from 54 to 08. If a Flight Plan is not available, the total amount of time added to the clock since liftoff is 24 hours, 46 minutes. It would therefore be possible to get a corrected GET or in effect an actual Ground Elapsed Time rather than an updated Ground Elapsed Time by subtracting 24 hours, 46 minutes from the GET time that we're currently showing in Mission Control. In other words, we're not showing 228 hours, 44 minutes and 22 seconds. To get the actual Ground Elapsed Time, from that updated GET time, it would be necessary to subtract 24 hours, 46 minutes from that time. We do have a clock in the Control Center which is counting actual GET time and does reflect that difference of 24 hours and 46 minutes. On the TV monitors, that would be the clock with the nomenclature TB 5 and currently, that clock is showing 203 hours, 58 minutes, 53 seconds.
203 58 58 England: Okay, Apollo 16. You've got a Go for spinup.
203 59 04 Duke: Okay. Thank you.
Public Affairs Officer: Tony England giving Apollo 16 a Go for spinup. That's the signal that they may begin the Passive Thermal Control mode, puting the spacecraft in a slow rotation of three revolutions per hour. Prior to the - following the PTC, after getting [the] spacecraft spun up, the crew will have completed all of the activities required before beginning their sleep period. At 228 hours 46 minutes [204:00] updated Ground Elapsed Time, this is Apollo Control Houston.
[No more communications on Day 10.
Public Affairs Officer: This is Apollo Control [at] 229 hours, 35 minutes [204:48] Ground Elapsed Time. Apollo 16 presently is 12,791 nautical miles out from the Moon approaching Earth at 4,700 feet per second. During the change of shift press conference just completed there have been no communications with Apollo 16. We'll continue to stay up live with the air/ground circuit until the final sign off. But it appears there will likely be a great deal of dead air.
Public Affairs Officer: This is Apollo Control at 230 hours, 7 minutes [205:20] Ground Elapsed Time. Apparently [the] Apollo 16 crew has indeed gone to sleep, without saying good night. Distance, 14,250 nautical miles out from the Moon, velocity 4,658 feet per second relative to the Moon. Spacecraft now weights 27,427 pounds and at 230 hours 8 minutes [205:21] Ground Elapsed Time this is Apollo Control, out.
Public Affairs Officer: This is Apollo Control [at] 231 hours 47 minutes [207:00] Ground Elapsed Time. Apollo 16 crew asleep at this time. No communications from them in over 2 hours - 2 and a half hours. Distance 18,747 nautical miles outbound from the Moon. Velocity 4,568 feet per second. For the statistical minded, here is some numbers on leaving the Moon's sphere of influence. The halfway mark in distance, the halfway mark in time. We exit the lunar sphere of influence in about 6 hours at a Ground Elapsed Time of 237 hours 27 minutes 51 seconds [212:41:49] and at which time the distance from the Moon will be 33,821 nautical miles. Height above the Earth at that time 187,827 nautical miles. The halfway point and distance will take place at Ground Elapsed [Time of] 266:39:00 [241:52:58]. The distance to both bodies, Earth and Moon at that time will be 112,726 [miles]. The halfway time in the Moon-Earth transit will take place at Ground Elapsed Time of 257:45:12 [232:59:10]. At the halfway point in time the distances are 87,593 [miles] from the Moon and 138,683 [miles] from the Earth. At 231:49 [207:02], this is Apollo Control.
Public Affairs Officer: This is Apollo Control [at] 232 hours, 47 minutes [208:00] Ground Elapsed Time. Some 3 hours, 12 minutes remaining in the Apollo 16 crew rest period. Crew apparently sound asleep at this time. Meanwhile the spacecraft is 21,445 nautical miles out from the Moon approaching Earth at 4,532 feet per second. And during this graveyard shift that's about all there is to say. At 232:47 [208:00], this is Apollo Control.
Public Affairs Officer: This is Apollo Control [at] 234 hours, 47 minutes [210:00] Ground Elapsed Time, One hour and 12 minutes remaining in the Apollo 16 crew rest period. However, they will likely sleep in another hour beyond this time. Apollo 16 presently is 26,754 nautical miles out from the Moon, approaching Earth at 4,484 feet per second. The Spaceflight Meteorology Group of the National Weather Service said this morning that weather conditions for the landing and recovery operations of Apollo 16 [on] Thursday are expected to be satisfactory. The planned landing area, near the equator some 1200 nautical miles south of Hawaii, has a weather forecast calling for scattered clouds, easterly trade winds at 10 knots, 3-foot seas, and a temperature near 82 degrees. At 234:48 [210:01], this is Apollo Control.
Public Affairs Officer: This is Apollo Control [at] 235 hours, 47 minutes [211:00] Ground Tlapsed Time. Although the wake clock shows 12 minutes remaining in the sleep period the crew actually will probably sleep an additional hour and half. No more than that unless they wake up and call the Control Center earlier than hour and half from now. Distance 29,421 nautical miles out from the Moon. Velocity 4,469 feet per second. Some of the major events coming up during the day would be the Mid-Course [Correction] 5 if it's actually performed. That still hasn't been pinned down yet why they're not [sic]. The velocity change is great enough to warrant doing it this time. The Trans-Earth EVA to retrieve the film cassettes from the Scientific Instrument Module, additional runs with some of the instrumentation in the SIM bay, Gamma Ray and X-Ray equipment. And that pretty well fills up the work dav with the next rest period scheduled to begin at about 252 hours 30 minutes [227:43]. At 235:49 [211:02], this is Apollo Control.
