235 37 16 England: Good morning, Apollo 16; Houston.

235 37 38 Young: Morning, Tony.

235 37 40 England: Good morning up there. Say, I think we may have driven your High Gain into the stops. Could you check on 225 the High Gain Flight Bus and Group 2? If one's out, push it in.

Public Affairs Officer: This is Apollo Control in the early wakeup some 5 minutes early because of the High Gain Antenna. Apparently some minor difficulty.

235 38 32 Young: They're in, Tony, and can't move it.

235 38 41 England: Which ones were out?

235 38 46 Young: They're in!

235 39 38 England: Okay, John, on that High Gain, could we put it to Pitch at minus 40, to Yaw at 90, Reacq, and Narrow?

235 40 04 Young: Okay, that's where we are right now.

235 40 08 England: Okay, and we understand that no circuit breaker was popped.

235 40 15 Young: That's correct. There was no circuit breaker popped.

235 40 21 England: Okay, thank you.

235 40 34 England: And, after you finish your post-sleep up there, before you stop PTC, we'd like to update your checklist or Flight Plan. We've got a couple of changes on the - the PTC initiation, there.

235 40 56 Young: Changes on initiation before we stop, huh? Okay. Okay, don't blow our record, now.

235 41 05 England: Okay.

235 41 17 Young: You're talking about the super gal, huh? I'm ready to copy, Tony.

235 41 23 England: Okay. Okay, for the PTC initiations at 260 plus 44 and 264:01, we'd like to change the PTC procedures and the G&C checklist to keep the PTC coning within plus or minus 3 degrees in pitch and yaw. Okay, if we could go to the G&C 8-2.

235 41 57 Young: Okay, why don't you just tell me first what the general scheme is, how you're going to do that, while we're getting the book out.

235 42 03 England: Okay, fine. We'll use you B/D roll, but we'll keep the pitch and yaw jets - D3, D4, C3, and C4 jets - on. And we're gonna leave the roll jets on, too.

235 42 32 Young: In other words, you want this thing to - to remain in attitude control throughout the PTC?

235 42 38 England: That's right.

235 42 44 Mattingly: Oh, delete the P from PTC.

235 42 49 England: You're right (laughter). I guess we'd call it ATC now.

235 43 01 Mattingly: There you go. How about AGS? You got to figure out what that stands for, but it's better.

235 43 17 Mattingly: You're a scientist; that shouldn't be hard, Tony.

235 43 29 England: Active galaxy st - scan?

235 43 31 Mattingly: Do you want us to, try - that's very close. You get a 95.

235 43 38 England: (Laughter) I want to quit your course.

235 43 45 Mattingly: (Laughter) Oh, It's right down there, John. How you doing on the High Gain? I don't know if you shifted to it or not; looks like we're where you could pick up, now.

235 43 59 England: We're gonna try it down here. If we lose comm, why, we'd like you to go ahead and try to acquire it yourself.

235 44 07 Mattingly: Oh, okay.

235 44 21 England: And let me know when you're ready with the G&C.

235 44 31 Mattingly: I'm ready. No. No.

235 45 12 England: Ken, Houston.

235 45 16 Mattingly: Go ahead.

235 45 21 England: Did you acquire or did we do that?

235 45 26 Mattingly: You did that.

235 45 27 England: Oh, good show. Okay, in the G&C Checklist, perform Steps 1 through 4. After the rates are damped in step 5 under the "Auto RCS select," use B/D roll and D3, D4, C3, C4 jets. And you might just sort of write this in at the side - not cross anything out because later on you'll go back to the normal procedure.

235 46 03 Mattingly: Roger; I understand.

235 46 04 England: Okay, in Step 6, use a minus 0.30 degrees a second, and 3.0 degrees in Noun 79.

235 46 20 Mattingly: Okay.

235 46 21 England: Anti delete the last two steps.

235 46 23 Mattingly: As long as we're remaining active, why - as long as we're remaining active, why are we trying to damp the rates, Tony?

235 46 49 England: Okay, I guess they're not going to let you - they're not going to ask you to damp it down too long. They're just going to get it down to a reasonable rate and then start it up.

235 47 00 England: Okay, and delete Step 7.

235 47 01 Mattingly: Okay. Roger. I understand.

[The PAO, Mission Control and Crew are using the updated GET, intended to align events to the Flight Plan. At this stage in the flight, the difference from the actual GET is 24 hours, 45 minutes and 52 seconds. See here for more details.]

235 47 10 England: Okay, and a note here for the PTC attitude at 275 plus 50 [251:03], use the normal PTC procedures. Okay, now we can go to the updating on the Flight Plan.

235 47 28 Mattingly: Okay, what you're really saying is that except for this - these two special things, we're just gonna do what we always do, right?

235 47 36 England: That's affirmative. I just say it the long way.

235 47 42 Young: All righty.

235 47 44 England: Okay, from 262 plus 00 [237:13] to 262:20 [237:33], we're gonna schedule in some geology debriefing for EVA-3 for John and Charlie.

235 48 38 Mattingly: Okay; Tony, I got that - it's written down.

235 48 40 England: Okay, fine. At 264:30 [239:43], change "Purge O2 Fuel Cell 1" to "O2 Fuel Cell purge." And then right under that, cancel out all that Mass Spec exercise between 264:35 [239:48] and 264:45 [239:58]. Essentially, all you've done is take all that out and you've done an O2 fuel cell purge and then ended up with an H2 fuel cell purge.

235 49 23 Mattingly: Okay.

235 49 24 England: Okay at 267:00 [242:48]-

235 49 30 Mattingly: Go ahead.

235 49 31 England: Change our - the High Gain Pitch and Yaw to Pitch, 9; Yaw, 257.

235 49 42 Mattingly: Okay.

235 49 43 England: From 268:10 [243:23] to 268:40 [243:53] - You're gonna love this. Schedule a TV press conference.

235 50 04 Mattingly: You knew we had it stowed, didn't you?

235 50 09 England: Well, we just waited ...

235 50 11 Mattingly: You knew we took two hours to do that yesterday.

235 50 12 England: ...until you had tucked it away.

235 50 14 Mattingly: Okay. Okay.

235 50 18 England: Okay, at 268:30 [243:43], delete "Charge Bat A."

235 50 34 Mattingly: That's done.

235 50 35 England: Okay.

235 50 36 Mattingly: Go ahead.

235 50 37 England: At 269:23 [244:36], delete "Alpha Particle/X-Ray Cover, Close; X-Ray, Standby; and Verb 49 maneuver to thermal attitude." Delete that whole block.

235 50 50 Mattingly: Okay.

235 50 53 England: Okay, delete all activities between 269:55 [245:08] and 270:10 [245:23] - Mass Spec, RCS jet test.

235 51 30 Mattingly: Go ahead, Tony.

235 51 31 England: Okay, at 270:50 [246:03], change your Verb 49 attitude to 090, 180, 010.

235 51 48 Mattingly: Okay, 090, 180, 010, at 270:50 [246:03].

235 51 52 England: Okay, and your High Gain attitudes there are Pitch, minus 75; Yaw, 40.

235 52 01 Mattingly: Minus 75 and 40.

235 52 05 England: And note that your Alpha Particle and X-Ray Cover are Open and X-Ray is On throughout the Skyli - Skylab contamination photos, so you just don't worry about that.

235 52 18 Mattingly: Okay.

235 52 19 England: At 271:15 [246:28], change your Verb 49 attitudes - 032, 299, 010.

235 52 36 Mattingly: Okay.

235 52 37 England: And your High Gain: Pitch, minus 40; Yaw, 229.

235 52 45 Mattingly: Okay, minus 40 and 229. And an attitude of 032, 299, and 010.

235 52 51 England: Okay, at 271:50 [247:03], change the roll in the Verb 49 attitude to 140. And the High Gain is ...

235 53 06 Mattingly: From 141 to 140?

235 53 08 England: ...Pitch, minus - Right. And the High Gain's Pitch, minus 47, to Yaw - and Yaw, 59.

235 53 18 Mattingly: Minus 47 and 59.

235 53 20 England: Roger. At 272:10 [247:23] -

235 53 27 Mattingly: Okay.

235 53 28 England: Verb 49 attitude, 088, 082, 041, and the High Gain: Pitch, minus 49; and Yaw, 220.

235 53 48 Mattingly: Okay, that's 088, 082 and, 041, and a minus 49 and 220 on the gain.

235 54 02 England: Roger. At 273 [248:13], delete "X-Ray, On."

235 54 09 Mattingly: Okay.

235 54 11 England: At 273:30 [248:43], delete "Alpha Particle/X-Ray Cover, Open."

235 54 18 Mattingly: Okay.

235 54 19 England: At 274:15 [249:28], on your Verb 49 attitude -

235 54 25 Mattingly: All right.

235 54 26 England: New attitude is 164, 134, 035; High Gain is minus 23 and 101.

235 54 42 Mattingly: Okay; 164, 134, 035; minus 23 and 101 at 273.

235 54 50 England: Okay. And that's all I've got.

235 54 56 Mattingly: Okay.

235 55 00 Young: Oh, shoot, Tony, you can do better than that. Haven't you got any more?

235 55 04 England: Well, we're - we're - I'm sure FAO will have some here in a few minutes, but that's guaranteed all until you get back.

235 55 12 Young: Oh, okay. Well, good. I don't want to see FAO stopping this quick.

235 55 28 England: And I guess we don't know why that High Gain hung up while you were asleep. We're going to just continue trying normal procedures.

235 55 39 Mattingly: Okay.

235 55 49 Duke (onboard): You mean the experiment?

235 55 51 Young (onboard): No.

235 55 52 Mattingly (onboard): (Garble).

235 55 55 Duke (onboard): What do you want - the shield?

235 55 57 Mattingly (onboard): That (Garble).

235 55 58 Duke (onboard): No.

235 55 59 Young (onboard): That was the Gainstep.

235 56 00 Duke (onboard): Well, it's (garble), but it's shield on the bottom.

235 56 04 Young (onboard): Oh. Oh. Excuse me.

235 56 05 Duke (onboard): Okay.

235 56 06 Young (onboard): No wonder I couldn't find it. I'd be over there looking for a month.

235 56 30 Young (onboard): (Garble).

235 56 31 Mattingly (onboard): Okay. Oh, that's why it didn't - that helps. I turned it off so I wouldn't keep you awake.

235 56 37 Young (onboard): You thought - you thought my ears were going bad, huh? All right, we'll cycle our Cryo fans. I'll start the watch.

235 56 47 Mattingly (onboard): Good. I got the watch.

235 56 50 Young (onboard): Speaking of starting watches, there's my watch. Come back here, you rat.

235 57 35 Mattingly (onboard): Excuse me, Charlie.

235 58 47 Young (onboard): Okay, where's that Super Gal located? Is that where it's at, huh?

235 58 52 Mattingly (onboard): 267.

235 58 54 Young (onboard): I wasn't very far off.

235 58 57 Mattingly (onboard): I can't believe that they can tell any difference. That 's roll - yaw.

235 59 03 Young (onboard): We didn't scratch anywheres close, did we?

235 59 06 Mattingly (onboard): Why we went to 189 when we could have gone to exactly the opposite up here, I don't know (garble).

235 59 24 Young (onboard): That doesn't make a lot of sense, does it?

235 59 28 Mattingly (onboard): No.

235 59 37 Mattingly (onboard): (Garble) in, but that doesn't (Garble).

Public Affairs Officer: This is Apollo Control. Apparently, the crew of Apollo 16 bright eyed and bushy tailed on the first call-up. Flight Plan updates read to the crew included a geology debriefing for Young and Duke on EVA-3. That's scheduled from ground elapsed 262 [237:13] to 262:20 [237:33]. Press conference with onboard television scheduled now at 268:10 [243:23] through 268:40 [243:53], duration of 30 minutes. The crew has also been instructed on procedures on setting up a - what is called "Super Galactic Plane Passive Thermal Control." Although they tended to call it "Active Thermal Control". We're up live with the air/ground circuit until the next rest period. At 260:46 [235:59] this is Apollo Control.

235 59 55 Mattingly (onboard): Well, what's going on here?

236 00 10 Young (onboard): It's not moving?

236 00 25 Duke (onboard): (Garble) here.

236 00 31 Mattingly (onboard): I don't - Well, we're supposed to swap, yeah.

236 00 39 Duke (onboard): Am I supposed to be on it all this time?

236 00 42 Young (onboard): Huh?

236 00 43 Duke (onboard): Am I supposed to be on?

236 00 44 Young (onboard): No.

236 00 47 Mattingly (onboard): What am I doing wrong, John?

236 00 50 Young (onboard): I'm sure I don't know.

236 00 54 Mattingly (onboard): How come my DAP isn't running?

236 01 00 Young (onboard): 11101. Okay?

236 01 25 Mattingly (onboard): Why don't those needles center? I think you didn't get any power to that switch.

236 01 39 Young (onboard): Check the group Rs.

236 02 08 Mattingly: Hey, Tony, I'd like to do a - a Verb 46 and I think that was one of the ones that they had on my list of things that I shouldn't do.

236 02 17 England: Okay. I'll check on that.

236 02 19 Mattingly: Could you - could you see what conditions I need to satisfy in order to do that?

236 02 24 England: Okay.

236 02 26 Mattingly: Like - I'm not sure whether I've got a switch out of position or what here, but it - it looks like the DAP isn't - isn't running. And I don't really understand why.

236 02 40 England: We'll work that.

236 02 44 Mattingly: Hey, I may have something out of configuration. I just don't see it right offhand.

236 03 04 Mattingly: I did find the switch.

236 04 00 Mattingly: How about our cycling the Cryo fans while we can take them back off.

236 04 09 Mattingly: Remembered it. Huh?

236 04 16 Duke: Did John forget to turn off the Cryos?

236 04 23 England: Yes, you can cycle the Cryo fans and our G&N says everything's all right here.

236 04 32 Mattingly: Okay. They're cycled. Yeah, we - I had the FDAI Select in 1; I was getting ready to do a GDC align when you - when you're - asked for these other things and I left it there and the needles weren't centering, so I was - I overlooked that one. Thank you.

236 11 25 England: And, Ken, you're Go to start PTC any time you're ready. You're damped well enough.

236 11 44 Mattingly: Okay.

Public Affairs Officer: This is Apollo Control, Houston; at 261 hours [236:13] Ground Elapsed Time. We've had a change of shift in the Mission Control Center. Phil Shaffer has now come aboard as the Flight Director, and our Capcom at this time, Henry Hartsfield. We'll standby and continue to monitor our conversations with the crew of Apollo 16. We're at 261 hours [236:13] Ground Elapsed Time, and this is Apollo Control, Houston.

236 15 03 Young: Okay, and the ATC is operating.

236 15 07 England: Okay.

Public Affairs Officer: This is Apollo Control, Houston; at 261 hours, 3 minutes [236:16] Ground Elapsed Time. We now show Apollo 16 at a distance of 129,502 nautical miles away from the Earth. Our Capcom, at least through the geology quiz, will be astronaut Tony England. Following the quiz, he will be replaced by Henry Hartsfield, who normally works this shift. Both are in the Control Center at the present time, and we're apt to hear from either in conversations with the crew of Apollo 16. We're at 261 hours, 4 minutes [236:17] Ground Elapsed Time, and this is Apollo Control, Houston.

236 19 30 Young (onboard): (Garble) meals.

236 19 31 Mattingly (onboard): Yeah. Okay; now - you got 6½, Charlie, and no - and no medication?

236 19 41 Duke (onboard): No. That's right.

236 19 42 Mattingly (onboard): Yes...

236 22 48 Mattingly: Okay, Houston. Standing by with the crew status report.

236 22 55 England: Okay. Go.

236 23 06 Mattingly: Okay.

236 23 09 Young: For the Commander, working on Day 11 to keep it in sync with the - with the clock around here. A-1 is down in the bow of the ship, stowed; A-3 is 7 hours; A-4 is none. For the CMP: B-1, 15067; B-3, 6½; B-4, none. For the LMP: C-1, 21159; C-3 is 6½; C-4 is none.

236 24 29 England: Okay, we copy that.

236 24 33 Young: And all those sleeps were good to better.

236 24 38 England: Good to better, huh? Okay.

Public Affairs Officer: Apollo Control, Houston; at 261 hours, 11 minutes [236:24] Ground Elapsed Time. That was John Young passing along the Crew Status Report to Capcom, Tony England. We show Apollo 16 now 129,121 nautical miles from the Earth, and travelling at a speed of 4,918 feet per second.

236 25 03 Young: Okay, and we're using - Yesterday we were using the Day 10 meals to try to help clean out the B-2, so we can stow the Mapping Camera film in there, and on that day for breakfast, the - on the - on the CDR's, scratch the fruit cock - fruit cocktail.

236 25 38 England: Okay.

236 25 41 Young: For dinner, scratch - for - for lunch, scratch the turkey and gravy and sub - substitute beef and gravy and add an orange drink, and then you can either scratch - We never got around to eating supper because we missed lunch and we substituted - we substituted sup - supper, or I mean lunch, for supper.

236 26 11 England: Okay, copy that.

236 26 23 Young: And on the CMP for breakfast, scratch the fruit cocktail, the sausage patties, and the spiced fruit cereal.

236 26 38 England: Okay.

236 26 41 Young: For lunch, scratch the vanilla pudding in a can; the white bread, 1; and the peanut butter parentheses WP; and add a chocolate bar and coffee.

236 26 58 England: Okay.

236 27 10 Young: For the LMP, for breakfast, don't scratch anything. For lunch, or supper, your choice, scratch the - turkey and gravy and add beef and gravy and scratch the vanilla pudding in a can; the white bread, 1; and the peanut butter. Okay?

236 27 38 England: Okay. We copy that. Ken didn't eat his peanut butter, huh?

236 27 46 Young: We couldn't find it after we cleaned out - after we cleaned out that locker to stow the Mapping Camera cassette, the peanut butter mysteriously vanished.

236 27 55 England: Oh, I understand. Charlie stole it.

236 27 50 Young: We're looking for the guy - we're looking for the guy with the key to the peanut butter locker right now.

236 28 11 England: You know, of course, you're going to have to eat up all that food on the day you lost.

236 28 20 Young: How about if we do that aboard the ship?

236 31 51 England: And, Apollo 16, the Gamma Ray Shield, On, per the Flight Plan.

236 32 21 Young: Okay, she's On.

236 32 23 England: Okay.

236 32 57 Young (onboard): Why would you...

236 33 01 Mattingly (onboard): Well, they were turning the power off there for a while because of a possibility that you - they thought that - you were sleeping, you might bang it.

236 33 12 Young (onboard): Kick it off, huh?

236 33 13 Mattingly (onboard): Yeah. And I guess I can't say you couldn't do that, because I - I caught myself when I was - the times I was knocking switches was when I was moving around trying to do things.

236 33 28 Young (onboard): I tell you, I fell asleep with my hand on the integral lighting the other day, and I - and it - and I woke up still holding on to it. Funniest thing I ever did in my life. Boy, that tape recorder switch's just going like crazy.

236 34 07 Duke (onboard): Okay. I (garble) to the last. If I eat all this, I'm going to explode.

236 34 11 Mattingly (onboard): What, Charlie?

236 34 12 Duke (onboard): If I eat all this, I'm gonna explode.

236 34 16 Mattingly (onboard): (Garble) peaches (garble).

236 34 17 Duke (onboard): I like those peaches, Ken.

236 34 40 England: Apollo 16, Houston. If one of you have a chance, would you read out the battery compartment pressure reading?

236 34 48 Young: 2 ...

236 34 49 Duke (onboard): 2.5

236 34 51 Young: ...2.5 and holding.

236 34 54 England: Okay.

236 34 59 Duke (onboard): That's what it was - When it was get ...

236 35 00 Mattingly (onboard): (Garble).

236 35 02 Young: Okay. Ken says he looked at it several times during the evening and it's been there most of the night.

236 35 09 England: Okay, fine.

236 35 32 Duke (onboard): Hey, John, could you spin around here? (Garble) behind you.

236 35 34 Young (onboard): Yeah, Charlie. Just a second.

236 35 36 Duke (onboard): Sure.

236 35 41 Young (onboard): Sir? Okay. Here's the Flight Plan. We're doing what we're supposed to be doing for a change.

236 35 55 Young (onboard): Here you go, Charlie.

236 35 59 Duke (onboard): Thank you.

236 36 08 Duke (onboard): (Garble) Oh, no. Here's another - another whole package. Excuse me.

236 36 14 Young (onboard): What have you got I can substitute for the cracking - for the grits?

236 36 23 Duke (onboard): (Garble).

236 36 26 Young (onboard): Not for the grits, no. I don't want to hurt your feelings, Charlie. I mean for my coffee.

236 36 34 Duke (onboard): I'll get you some out of the food locker over here.

236 36 39 Young (onboard): Yeah, maybe a dark drink. Not bad. You mix this with coffee and you know what you got? It's bad.

236 36 51 Mattingly (onboard): (Garble).

236 36 54 Young (onboard): (Laughter) I'm going to try that and see what they say. (Laughter)

236 36 59 Duke (onboard): What is that?

236 37 04 Young (onboard): I'm going to mix this with coffee and put it in - down in there and see if they can tell what it ...

236 37 08 Mattingly (onboard): (Garble) Why don't you do that?

236 37 10 Duke (onboard): Surprise.

236 37 23 Young (onboard): Oh, oh (garble). That gonna be funny. (Laughter)

236 37 42 Young (onboard): Charlie, these grits are all right.

236 37 44 Duke (onboard): They are (garble).

236 37 45 Young (onboard): Mm-ham. Just what I'd always eat when I was starving down South.

236 37 56 Duke (onboard): Kept people alive.

236 37 58 Young (onboard): Sure did.

236 38 12 Young (onboard): Kept lots of people alive. You know the old saying.

236 38 21 Duke (onboard): I think these are better than the Skylab peaches.

236 38 25 Young (onboard): What we used to say ~ what my roommate used to say - He was from New Jersey - he said you had to be near dead to eat grits. I'll never forget the time that he - we were going through - eating at the mess hall at Georgia Tech, and he thought he was getting some Cream of Wheat ...

236 38 47 Duke (onboard): Yeah.

236 38 48 Young (onboard): ...and they put it on his plate, and he couldn't understand why they didn't put it in a bowl. Man, he spit grits.

236 38 51 Duke (onboard): (Garble) had them.

236 38 58 Young (onboard): He spit grits for 20 feet when he put them in his mouth - He thought they were trying to kill him.

236 39 09 Duke (onboard): (Garble) down, John (garble).

236 39 13 Young (onboard): Yeah.

236 39 14 Duke (onboard): (Garble).

236 39 15 Young (onboard): Sorry.

236 39 38 Crew (onboard): (Cough).

236 39 55 Young (onboard): Well, another thing I ought to do a lot of exercise today. Get the old cardiovascular system back in shape.

236 40 19 Young (onboard): First thing we ought to do is go to work on the Entry Checklist, right? Entry Stowage List?

236 40 30 Duke (onboard): What for? We haven't figured it out.

236 40 35 Young (onboard): We could get the TV.

236 40 40 Mattingly (onboard): That's way back over here. Right on the very bottom of everything.

236 40 54 Duke (onboard): We should have thought of that.

236 40 56 Young (onboard): Huh?

236 40 58 Duke (onboard): We should have thought of that.

236 41 00 Mattingly (onboard): (Garble) changing (garble).

236 41 03 Duke (onboard): Yeah.

236 41 13 Duke (onboard): I never could ...

[No CM transcript for 11 minutes.]

236 52 50 Young (onboard): What's that?

236 52 52 Mattingly (onboard): We're getting better. Started late and got through earlier.

236 52 55 Young (onboard): That was real organized this morning, Ken.

236 52 57 Duke (onboard): It worked great. You just cutting that meat.

236 53 01 Mattingly (onboard): Yeah. That seemed to work out pretty good (garble) pretty good?

236 53 07 Young (onboard): We should have done that all along - I guess.

236 53 08 Mattingly (onboard): Yeah. We should have (garble).

236 53 11 Young (onboard): Don't know it, until you do it.

236 53 12 Duke (onboard): (Garble) ...

236 53 13 Young (onboard): We ought to recommend that to the 17 guys.

236 53 15 Mattingly (onboard): The trouble is, you know, you try to talk to the guys before the flight about this and ...

236 53 17 Young (onboard): (Garble) about a year before the flight.

236 53 20 Mattingly (onboard): ...things like how you defecate, how (garble) you have to be. They ain't gonna listen.

236 53 26 Young (onboard): Why, no.

236 53 29 Mattingly (onboard): What else (garble)(garble) probably won't pay any attention (garble).

236 53 36 Duke (onboard): The only - I did listen to Stu Roosa on that thing (garble) He said get naked and be prepared to get stuff all over your hands. And it happened.

236 53 46 Crew (onboard): (Laughter)

236 53 50 Young (onboard): Just like he said, huh? There's no consolation in that.

236 54 04 Young (onboard): Careful.

236 54 06 Duke (onboard): John, what can we do on the stowage or something that - maybe just to occupy my mind ...

236 54 08 Mattingly (onboard): Well, you know they got a geology debrief for you guys at 262 hours.

236 54 15 Young (onboard): When is the press conference?

236 54 18 Mattingly (onboard): At 268.

236 54 19 Young (onboard): (Garble).

236 54 21 Mattingly (onboard): And I really want to - I want to take some photographs of the - of the (garble).

236 54 31 Young (onboard): Okay.

236 54 33 Mattingly (onboard): And I would like to take photos (garble) while you guys eat - interior photos (garble). ?

236 54 41 Young (onboard): Okay.

236 54 44 Mattingly (onboard): I really think - I need (garble) - the only thing that you could really have (garble) is plastic (garble).

236 54 50 Young (onboard): You can't get that. I (garble) them my lightweight headset. I got to try that thing. Is there a way to get that? It's down there in the A-8, isn't it?

236 54 56 Mattingly (onboard): It's a pain.

236 54 58 Duke (onboard): I'm going to take mine off ...

236 54 59 Mattingly (onboard): ...(garble) supposed to be. They're absolutely worthless.

236 55 02 Young (onboard): You want to wear these things for the press conference ?

236 55 04 Mattingly (onboard): Think that's only way they can hear you.

236 55 07 Young (onboard): Okay.

236 55 10 Mattingly (onboard): That's wh - one reason I've been wearing mine all the time is it's the only way I can get Houston. The DSE won't pick up the lightweight set hardly at all, unless you do what Charlie is doing, otherwise you won't be (garble).

236 55 21 Young (onboard): Probably be better if you ...

236 55 23 Duke (onboard): Take off your neck.

236 55 26 Mattingly (onboard): (Garble) you in.

236 55 29 Duke (onboard): (Garble)?

236 55 30 Mattingly (onboard): Yeah.

236 55 38 Young (onboard): Thank you.

236 55 45 Duke (onboard): (Garble).

236 55 46 Mattingly (onboard): Open?

236 55 48 Young (onboard): How many did we have? (Garble).

236 55 58 Young (onboard): Wonder why they wouldn't be happy just to have a press conference on the radio?

236 56 01 Mattingly (onboard): Too (garble) of the (garble).

236 56 06 Duke (onboard): Oh, is that right?

236 56 07 Young (onboard): I don't know - I don't know how we're going to set this thing up.

236 56 09 Duke (onboard): You can set it right back here on this bracket, John.

236 56 12 Young (onboard): Oh, yeah.

236 56 13 Duke (onboard): And point it right - it'll - and point it to the LEB, and we can all three get in the picture.

236 56 17 Mattingly (onboard): I'll get in the (garble) while you guys can get in the picture, okay?

236 56 21 Duke (onboard): That's at 262 - 262 you say we got a geology debriefing?

236 56 28 Young (onboard): Where does this here go, I wonder? I wonder if they think that this thing is supposed to stay in here with a ...

236 56 36 Mattingly (onboard): Yeah.

236 56 37 Young (onboard): ...pressure suit.

236 56 41 Duke (onboard): That'll go.

236 56 46 Mattingly (onboard): Oh, I'm sure it will. I just - (garble) like (garble) have had it in there because actually it won't go (garble) ...

236 56 54 Young (onboard): Yeah.

236 57 00 Mattingly (onboard): (Garble) a box of (garble)?

236 57 05 Duke (onboard): Oh, maul going to be (garble).

236 57 09 Young (onboard): Hey, let me - let me - Okay, Charlie ...

236 57 12 Duke (onboard): That's your friend.

236 57 14 Young (onboard): Charlie, don't stomp it like that. Let me see if I can get this in there. Okay?

236 57 19 Duke (onboard): I think you can now (garble). I got some (garble) going in there. Well, I'll just let them float by you.

236 58 28 Duke (onboard): I know what I'm gonna do - brush up my teeth.

236 58 39 Crew: (Garble) (laughter).

236 58 43 Mattingly (onboard): No, I don't have the urge yet, you guys. It'll be a couple of more hours. Right in the middle of the press conference.

236 58 49 Young (onboard): Right.

236 58 51 Duke (onboard): Well, we got to sign off now.

237 11 41 England: Apollo 16, Houston.

237 11 47 Young: Go ahead.

237 11 49 England: Okay. I tried to get Hank to send this up, but he wouldn't touch it either. I guess we'd like John on the biomed today and Charlie on it tonight. And just a reminder, for today we'd like items 5 and 6 in the crew status recorded.

237 12 10 Young: Yeah, we - We're working both of those problems in.

237 12 23 England: Okay, and we'd like to scrub the P52 at 262:30.

237 12 40 Duke: That was the only thing he had that he's looking forward to all day, and you scrubbed it.

237 12 45 Mattingly: You know how to hurt a guy, don't you?

237 12 51 England: We're just trying to give you some time to hunt for the peanut butter.

Public Affairs Officer: This is Apollo Control, Houston; at 262 hours [237:13] Ground Elapsed Time. We now show Apollo 16 at a distance of 126,742 nautical miles away from the Earth and now travelling at a speed of 4,982 feet per second.

237 14 11 Mattingly (onboard): (Garble).

237 14 12 Duke (onboard): No, I don't. They want John on biomed. Me tonight.

237 14 26 Young (onboard): You know, when I put my biomed on, my heart starts hurting (Garble).

237 14 36 Duke (onboard): Why don't we stick the pills down the Volkswagen pouch, Ken?

237 14 42 Young (onboard): I'm going to get in my seat to put this biomed on so it won't interfere with anybody.

237 14 50 Mattingly (onboard): Okay.

237 14 51 Duke (onboard): Hey, John.

237 14 52 Young (onboard): If it won't interfere with anybody, I will.

237 14 54 Duke (onboard): Hey, John. Why don't you quit getting up out - in your seat? Nice place to put the biomed on.

237 15 00 Young (onboard): That's right; my heart feels good.

237 15 09 Mattingly (onboard): (Garble) get outside on EVA (Garble).

237 15 16 Young (onboard): (Laughter) Shall we tell them that?

237 15 20 Duke (onboard): To what, did he say?

237 15 38 Young (onboard): Charlie, you going to have to help me position these.

237 15 40 Duke (onboard): Okay; I'll be glad to.

237 15 52 Duke (onboard): The little dealies are right here.

237 15 54 Young (onboard): Oh, yeah?

237 15 55 Duke (onboard): On the other end. Right - right here are the stickums, and the - and the sponges are in here.

237 16 39 Duke (onboard): (Sneeze, sneeze) There I go again.

237 16 49 Young (onboard): Don't hurt your eyes, Charlie ...

Public Affairs Officer: Apollo Control, Houston; 262 hours, 3 minutes [237:16] Ground Elapsed Time. We're standing by now for the geology.

237 16 48 England: Apollo 16, Houston. Whenever you're ready for the geology, we'll press on with that.

237 16 58 Mattingly (onboard): Ready, John?

237 16 59 Young: Yeah, we're ready.

237 17 01 England: Okay. Our first question here on the portable magnetometer - I forgot to re - I forgot to ask you. It was my omission. I was wondering what the temp label on the - on the electronics box read, if you remember.

237 17 21 Young: Tony, you got to be kidding.

237 17 24 England: I was afraid of that. Okay. And for Charlie there, we'd like to verify that on the third EVA when he was driving out to Station 11 with the polarizer on, that he used nominal camera settings. He didn't allow for the polarizer.

237 17 51 Duke: I did just what was on the top of the camera, Tony. Filter - I used 5.6 at 1/250 in the right position.

237 18 01 England: Okay. That's fine - that's great - That's what we needed to know. Okay. The next question we'll - we'll get when we get the rocks back, but I think - Well, maybe the best way to do this is to describe a theory that's coming up as a result of the rocks you've - that you saw there. It looks as if - or - A possibility is that an older theory that was discarded a few years ago may be the right one, that the Cayley is an outer fluidized ejecta from Imbrium. Fra Mauro would be an inner ring, and then Imbrium sculpture would be outside of that, and then the Cayley would be sort of slosh that filled up all the valleys farther on out. But some of the questions that the geologists are - are pressing here is something that might help them define that. And a lot of it is that they're just - can't wait for the rocks to get back. But anyway, at Station 11, you described some rocks you thought to be tuff. Looking back at Station 5 and 6, after seeing these at 11, do you think you might have seen the same kind of rock there? What we're thinking about is where you described the - the square crystals and the needle-like crystals in clasts. And also, in the same question, were these crystals by themselves or were these - I mean, were the cras - clasts single crystals or were the crystals in clasts?

237 19 38 Duke: Recalling Station 11, the - the rocks - that big rock in particular was a two-rock breccia, and - I feel. And within the - within the bluish-black matrix, which made up one clast - one of the rock types - there were needle-like crystals in that. And the white matrix also had crystals in it.

237 20 19 England: Okay. And how - how does - how did those rocks compare to what you saw at station 5 - 5 and 6?

237 20 31 Young (onboard): I knew they were going to ask these questions. I - may be -

237 20 40 Young: Tony, I'm afraid I'm not gonna do any better with the answer to these questions than I do on an average field geology trip where you got 10 stations.

237 20 49 England: Understand.

237 20 50 Young: And the rocks - You know, the rocks that we're picking up at 5 and 6 - that was a long time before Station 11 and -

237 21 00 England: Understand. Don't - don't worry about it ...

237 21 01 Young: And I can't remember what the dang rocks looked like, to be honest with you.

237 21 04 England: We're gonna have an antenna switch.

237 21 11 Duke (onboard): I think there were some of the same, John.

237 21 14 Young (onboard): Yeah, but I mean it's entirely speculative to answer a question like that on ...

237 21 34 England: Okay. I'll try to stick here to questions that were impressions, and we're going to get the rocks back anyway. I don't - I don't really think there's any point in pressing - pressing with questions where we'll get the answers in a few days. Outbound on EVA-3, you noted one to five-meter craters. And then, 10-meters craters going north and you called them secondaries. We're wondering what evidence there was that - if any, that they came from North Ray. Do you think you saw any secondaries from North Ray? And if so, where would they be? And could you compare them to the size and character of the South Ray secondaries?

237 22 21 Duke: There was out - out around Palmetto. There were a couple of craters, if I recall - I don't know f - exactly whether it was Palmetto or not, but as you're going out that way, there were some craters with some blocks in them. And that's the reason I called it secondary. They - they were not as fresh - in fact, craters going toward North Ray were a lot more subdued than the craters going down to Stone Mountain. The North Ray had - something had - either they're older or something, but they were a lot more subdued and there was less blocks around. But we did have one or two that had some blocks in them, and that's why I called them secondaries.

237 23 13 England: Okay. Were the blocks as angular as the ones you described from South Ray?

237 23 23 Duke: In general, our impressions were no.

237 23 26 England: Okay. As you were coming off of - and going up into North Ray area, could you give a guess at the relative proportions of - and the size and shapes of the white and the dark rocks.

237 23 51 England: In other words, was there a change ra - radially outward from North Ray?

237 24 04 Young: Yeah, this is just an impression, Tony. But I'd say that the - that the dark rock was less prevalent as you went outbound, generally speaking - as you went away from the crater.

237 24 21 England: Okay.

237 24 22 Young: I could be 100 percent out - wrong on that. But we sure drove over a lot of - in the regolith there in particular. The upper layer in regolith, which contained these - I mean the - the ejecta blanket - which contained - the upper layer in the ejecta blanket contained a lot of boulders with just their heads sticking through, and those were the ones I was looking at because I was trying to go around them. And they - and I don't ever remember seeing a - a dark brecc - breccia-like rock in those boulders.

237 25 01 England: Okay, sounds good. And that very large rock you sampled up there, Charlie, you mentioned there was white and dark rock in the one rock. Could you describe the contact? Was one contained in the other, or did the contact meander through the whole rock?

237 25 18 Duke: Just sort of meandered through, Tony. It was a - it was a - again I'll say a two-rock breccia, where it was a white and the black. And the clasts were very large, up to a meter size. I think the - the predominant rock was black. At least, the overall color gave you a black, but when you looked closely, you could see white clasts in it. So the - and the contact just meandered. I think we've got a couple of close-ups of - of how the contact just meandered through. It was sort of a angular clast in this predominantly blackish matrix.

237 26 03 England: Okay. The white rock, was it - that was in this big boulder - was it like the white rock that you sampled to the southwest of where you parked the Rover?

237 26 14 Duke: Yes, it was all - yes, uh-huh.

237 26 17 England: Okay. Incidentally, that shadow cone that. you saw on the big boulder - Did it - Did the surface on the cone go right through the clasts, or did the clasts poke out kind of like nodules on the cone?

237 26 35 Duke: Well, they - No, it didn't. The shadow cone was in - was fortunately, or unfortunately, depending on your point of view, in - in the black matrix. And it was - it was a crystalline rock where the shadow cone occurred.

237 26 50 England: Okay. Understand. Okay. Now that you've seen both North and South Ray ejecta blocks, could you say a few - a little bit about the ray material in the area from the LM to Flag? Do you feel that all that material is characteristic of the bigger ray blocks that you identified near either North Ray or South Ray?

237 27 24 Young: Yeah. I ...

237 27 26 England: Go ahead.

237 27 27 Young: I guess my impression might be that some - at some places, we had some of each and - but most of it was from South Ray. And around the LM, I'm - We saw - Once we got going toward North Ray, those - that material around the LM, by gosh, the breccia - and I collected several of them at that last Station - in hand specimens - some of them were like the material we got out of South Ray, clear of South Ray blanket, and - but several of them were from North Ray. At least, that was my impression.

237 28 14 England: Okay. Understand, We always had the feeling ...

237 28 17 Young: I'd say the most of them for - from South Ray.

237 28 19 England: Okay. We seem to have the feeling that the rocks you were describing in the LM area were just somehow just a little bit different than what you were picking up either down South or up North. I guess we'll get that all straight when the rocks get home.

237 28 36 Duke: Tony, I think that's - that the breccias were different. We've been - Maybe I'm going way out on a limb when I say this, but you - we've been collecting little fragments that have been floating around the cockpit here and looking at them, and they're crystalline - crystalline fragments that - with little white powdery exterior on part of it, and it - chalky appearance. And to me, this is - was characteristic of the rocks - some of the rocks around the Cayley, which - now I'm really leading to a tuff breccia - but the matrix being the ash with these crystalline frags, and the crystalline frags looked just like the rocks - the crystalline rocks around North Ray. At least, the black ones - at least, the couple I found here floating around. Now that's not to say that the fragments are - there are some fragments from whitish rocks, but they were a little bit dif - more difficult to see in this white matrix of what looks like tuff now, because it's very powdery.

237 30 03 England: Okay. Understand. I wonder if you could describe that - those vesicles in that rock at Station 13.

237 30 15 Duke: Well, they looked like - I call them drill holes. Let's see if John has a different word for it.

237 30 37 Young: They look like those pipes that you see in rocks. Like Charlie says, they just look like drill holes.

237 30 48 England: Okay. Understand ...

237 30 49 Young: And they were about a couple of - up to 2 to 3 centimeters across.

237 31 00 England: Okay ...

237 31 01 Young: ...in diameter, and perfectly circular. It appeared to me to be.

237 31 04 England: And how deep did they go? Could you tell - I mean, did they go straight in, or did they seem to meander around?

237 31 12 Young: They seemed to go straight in, and I couldn't tell how deep they were, because they only go in a - They disappear from sight. I didn't try reaching into any of them.

237 31 21 England: Okay.

237 31 22 Duke: Tony, they were - there wasn't anything in them. You could just look in and you'd just - and they looked clean, and - and - just like somebody drilled out the rock.

237 31 34 England: How about the orientation? Were they all perpendicular to the surface, or did they all have a preferred orientation?

237 31 49 Duke: I got the impression that they were parallel to the - to the surface. The rock was - As you stood and faced the rock, you could see - see these little holes sticking out at you that - with most of them parallel to the - to the regolith.

237 32 13 England: Okay. How about when you went around on the other side? Did they poke out at you there, or were the - What I'm trying to get a feeling is - Did it indicate a top and bottom in the rock, or did it just poke out all over the rock?

237 32 33 Duke: I'm - We don't - we only remember seeing them on one side, Tony. And that was the south side or the east side of the rock. The rock was facing - the side we saw them on was away from North Ray.

237 32 46 England: Okay. Understand.

237 33 01 Duke (onboard): You need some help with that, John?

237 33 03 Young (onboard): I'll make it, I think. It's run off somewhere.

237 33 09 England: Okay. And - Stand by.

237 33 51 England: Okay. Charlie, just before you left the - or during the LM closeout time, you started to make a remark about the change in character between the regolith - between the LM area and Stone Mountain, and somehow we got interrupted there and you didn't finish your statement. I wonder if you could finish what you're going to say - if you happen to remember? Can you characterize the difference in regolith between the LM area and Stone Mountain?

237 34 25 Duke: Stand by one on that one.

237 34 27 England: Okay.

237 34 29 Duke (onboard): Did -

237 34 32 Young (onboard): What you say, Charlie?

237 34 33 Duke (onboard): Those two regoliths seemed to be pretty - pretty much the same, sort of loosely consolidated and you sink right in. The one that I thought was impressive was up at North Ray where you - where it was very shallow, and you didn't sink in at all. Did you - do you remember anything being different about the two regoliths - between the LM and Stone?

237 34 59 Young (onboard): No, I sure don't. We never stopped between the LM ...

237 35 02 Duke (onboard): No, I mean between - say, up on Stone Mountain and at the LM.

237 35 09 Young (onboard): Well, the one up at Stone Mountain was clearly a - We just sunk in more because of a lot of down-slope debris ...

237 35 15 Duke (onboard): Yeah.

237 35 16 Young (onboard): ...in there. I'm sure of that.

237 35 22 Duke: Tony, I think that - We're just sitting here trying to decide - recall, and I - right now the only impression is that you tended to sink in more up on Stone Mountain, which could be down-slope movement of particles, and - It was a - just very loosely consolidated up there. Everywhere you'd - you'd step, you'd sink in a couple of inches. And on the slopes around the LM, it was the same way. And even, in fact, where we landed. Up around the ALSEP site, it was very loosely consolidated, and as you walked you could - your foot would leave quite a imprint. And once we had pretty well turned over the surface around the LM and up on Stone, it would look like freshly raked ground and - to me. Stone Mountain - Smoky Mountain - or excuse me, North Ray, wasn't like that at all. It was very thin regolith and as we commented, we had a tough time raking because it was so rocky right up - within a couple of centimeters, at the top of the regolith. Over.

237 36 47 England: Okay. Understand. I think your down-slope movement there on Stone was probably - probably right. Although that wouldn't explain why it was harder at 5 and 6 than at 4. Well, anyway. Next question here - On that half-orange-sized rock that you put on the LPM, wonder if you could estimate - estimate how common that type rock was around.

237 37 22 Duke: Well, John picked up one just like it up on - It was a grab sample up on Sto - yes, Stone Mountain. And it was one of the crystalline rocks with that sugary crystalline texture to it.

237 37 38 Young (onboard): Like whitish rock?

237 37 40 Duke (onboard): Huh?

237 37 41 Young (onboard): It was the whitish rock?

237 37 42 Duke: Huh? Yeah. And it was one of those whitish rocks that was a little dusty. I think that - I think it's fairly common. We'll just have to see when we get the samples back, but it was my impression it was one of the three predominant rock types there.

237 37 56 England: Okay. Understand. And the soil at Station 8 - was it white underneath the top surface like you described up at Station 4 and a lot of other stations?

237 38 16 Duke (onboard): I can't remember. I don't think so. Do you remember that, John?

237 38 27 Young: We kicked - we kicked some of that, and I - I can't remember whether it was or not at Station 8.

237 38 36 England: Okay.

237 38 37 Young: I think it - Anyway, we sampled the soil sample there, and it's in the - it's in - it's in the box somewhere. But I can't - I certainly can't remember whether it was a - white underneath or not.

237 38 51 England: Okay. Understand. And just subjectively, could you compare - now that you've been up fairly close to Smoky and on Stone - could you compare the two - two structures?

237 39 09 Young: They looked the same to us.

237 39 13 England: Okay. Well, that's all of the geology...

237 39 15 Young: I - Okay, I wouldn't be surprised but what they aren't the same. When Ken and I and Charlie looked at it in this real low Sun angle, I - I guess that's - As far as geometric form, it certainly looked - it was the hummocky material from the Descartes region is the way it looked. Right across Smoky - right through that whole region, it looked like a single unit, and - and I guess that would be my interpretation of it at this point. But it's pure speculation, but I would guess that tonight. I wouldn't be surprised but that we don't find a lot of these rock types on one region very close to another region being about the same.

237 40 08 England: Okay. Understand. The reason ...

237 40 09 Duke: Tony - That was - I was just going ...

237 40 13 England: Go ahead, Charlie.

237 40 14 Duke: ...to add to that, I was just - I had the same impression. Looking at the - the South Ray, with the black and white streaks up the wall - up on the interior of the crater, and also at Baby Ray, being very stark in contrast. And then in North Ray, having that same impression but more subdued. And the rocks appearing to be very similar - I think there's a good lateral - and you guys can demolish this when you analyze the rocks, but right now my impression is that - the - the two craters penetrated are very similar - or two very similar rock units. The white and the bluish black.

237 41 11 England: Okay. Understand. The reason for a lot of these questions - and we know the answers are in the rock boxes and bags there and we'll all get when you get home. But there's a lot of interest since the model - the model that we have of the whole area is being changed because of the high aluminum to silicon ratios and because of all of your rock descriptions there. And everybody's ...Well, we switched antennas there. There's a lot of push here to reformulate a new model. The press is kind of pushing, and you'll probably get some questions this afternoon in your press conference. I was wondering if there's anything you wanted to ask the geology team about this - this new model, since I don't think you've ever been briefed on it.

237 42 09 Duke: No, I'd sure never heard it was slosh from the Imbrium at the Cayley.

237 42 14 Young: I'd say it's premature to be making those kind of statements, Tony. And I would like to wait until we get all that data in and take a look at it. It's just too soon to be on - on hearsay and - and - and not having the real evidence and not having the - all the data analyzed. It's too soon to be making any major conclusions about the region. It's just - I can't see how you could do that.

237 42 38 England: I sure agree with you, John. But, you know, everybody's - Everybody's excited and trying to press with it. But, anyway, I thought you might want to - to hear a little bit about that, if you're going to be asked on it this afternoon. That isn't - Now, of course, that isn't to say anyone's saying that Kant Plateau or Descartes Highlands are slosh. It's just the Cayley part. Anyway, that's all - that's all we have here, if you just want to press on there.

237 43 11 Young: No, I just don't see how you can come to that conclusion this quick without any evidence, Tony. It's - It'd be nice to do that, but I - boy, I would - I would not press for that sort of thing this early in the game. And I wouldn't answer questions to anybody to amount to anything on that kind of stuff because that's too speculative.

237 43 30 England: Okay.

237 43 31 Young: In other words, it ain't good - it ain't good science.

237 43 35 England: Yeah, John. I think - I think you're right on, and I hope they heard you in the backroom, because I - I think I said the same thing this morning.

237 43 59 England: And we have a slight change to the Flight Plan at 264:10. We'd like to change the Noun 79 deadband to 2 degrees.

237 44 18 Mattingly: Okay. The Noun 79 changed to 2 degrees at 264:10.

237 44 24 England: Roger. And I'll see y'all tonight. I'll come back and tuck you in.

237 44 32 Mattingly: Okay, Tony. Thank you.

237 44 35 England: Thank you.

Public Affairs Officer: This is Apollo Control, Houston; at 262 hours, 31 minutes [237:44] Ground Elapsed Time. Apollo 16 now 125,279 nautical miles away from the Earth and travelling at a speed of 5,022 feet per second. That was Tony England closing off his conversation on geology with the crew of Apollo 16. Our Capcom from here on will be Hank Hartsfield. We're at 262 hours, 31 minutes [237:44]. This is Apollo Control, Houston.

237 48 17 Hartsfield: Apollo 16, Houston.

237 48 21 Duke: Hello.

237 48 22 Young: Go ahead, Henry. Good morning to you.

237 48 25 Hartsfield: Good morning. Like to give you a little change here - or an addition, I guess, at 264:50 [240:03] - waste water dump. Says there we're supposed to specify the percentage and that's 35 percent. However, we'd like to call the start and stop - start and stop of that maneuver. EECOM would like something to do this morning.

237 48 52 Mattingly: Okay. You going to put us in attitude and do a midcourse correction with it?

237 49 02 Hartsfield: I don't guess we need that ...

237 29 04 Duke: Tell EECOM we got some - Hey, Henry. Tell EECOM we got some good pictures of a dump when we were station-keeping up there while y'all were deciding whether we could land. Ken did his dump, and we had perfect lighting for it and so we got some DAC film of it and it was really coming out of there.

237 49 25 Young: Not only that, he had perfect position on the station-keeping when he started to dump and it just pushed him right over to the - It just pushed him right over out of plane.

237 49 37 Hartsfield: Hey, I bet that was pretty, too, wasn't it?

237 49 42 Young: Yeah.

237 52 37 Duke (onboard): See how that stuff powders off on your fingers. Look at that. Look at that white come off. Then that leaves that crystal. Now, you got nothing left but the crystal.

237 53 10 Young (onboard): Slosh from Imbrium. What a bunch of bull. (Laughter)

237 53 16 Duke (onboard): I wouldn't believe that in a million years.

237 53 20 Young (onboard): Yeah.

237 53 25 Duke (onboard): They got - they got a new model for the - the Cayley. They said it - Oops! - they say it's slosh - it's a slosh from Imbrium.

237 53 40 Mattingly (onboard): Bull.

237 53 41 Duke (onboard): That's my opinion, too.

237 53 44 Mattingly (onboard): That - If it is, then that's a slosh all over the back side of the Moon.

237 53 48 Duke (onboard): Yeah. John and I were just talking. Our - my theory is that the Cayley - We did see some endogenic craters and that - and that - the Cayley is really a tuff breccia - the - the - the plain, and it - because the crystals in this tuff are the same - like this one right here - looked the same as those big rocks that we found up at North Ray and also in the adja - in the secondary craters out of South Ray. So underneath, you could hypothesize a model, and the rocks might prove me entirely wrong ...

237 54 22 Hartsfield: 16, Houston. I've got a few deletions in your Flight Plan.

237 54 29 Duke (onboard): ...you could hypothesize ...

237 54 30 Young: Hey, there you go.

237 54 31 Duke (onboard): ...a model of an underlying ...

237 54 32 Young: Just a second.

237 54 33 Duke (onboard): ...crystalline basement.

237 54 34 Young (onboard): You got a pencil, Charlie?

237 54 35 Duke (onboard): Huh? Yeah.

237 54 36 Mattingly (onboard): (Garble).

237 54 37 Young (onboard): Huh?

237 54 38 Mattingly (onboard): (Garble).

237 54 39 Duke (onboard): No, it's not, either. Somebody swiped it.

237 54 45 Mattingly (onboard): I just don't find any (garble) basement rock anywhere (Garble).

237 54 50 Duke (onboard): I'm not - I'm not - I'm not saying total basement; I'm just saying ...

237 54 55 Mattingly (Young in CM transcript): Okay. Go ahead.

237 54 55 Duke (onboard): ...crystalline rock. And they were crystalline, Ken, just a sugar ...

237 54 57 Hartsfield: Okay, at 266 hours.

237 55 00 Duke (onboard): Huh? They were not breccias, I guarantee you.

237 55 06 Mattingly (Young in CM transcript): 266 hours. Go.

237 55 08 Hartsfield: Roger. Delete "Gamma Ray, Shield, Off."

237 55 13 Duke (onboard): You could see the cry - that rock was a homogeneous rock, and you could see the crys - you could hold it out, and you could see the crystals.

237 55 19 Hartsfield: And a little further down there at about 266:15, delete that whole line where it refers to the "Gamma Ray, Gainstep, On," et cetera.

237 55 25 Duke (onboard): Just tells me that I found a rock that's a crystalline rock, and it's not a breccia in the true sense of the word.

237 55 33 Duke (onboard): That somewhere down there ...

237 55 34 Mattingly (onboard): (Garble) breccia. (Laughter) (garble) ...

237 55 32 Mattingly (Young in CM transcript): That's deleted.

237 55 35 Hartsfield: Okay. And at 268 hours, at the top of the page - Page 374.

237 55 39 Duke (onboard): That's right, but that is not the ...

237 55 44 Mattingly (onboard): (Garble) say accretion (garble) never have (garble) down there ...

237 55 43 Young: Go ahead.

237 55 44 Hartsfield: Delete that Gamma Ray comment.

237 55 49 Duke (onboard): Do what?

237 55 50 Mattingly (Young in CM transcript): (Garble) never had (garble) accretion (garble) ...

237 55 56 Mattingly: Okay. Go ahead.

237 55 56 Duke (onboard): Well, accretion does mean molten.

237 55 57 Hartsfield: That's all of them for right now. Thank you a lot, fellows.

237 55 59 Mattingly (onboard): (Garble).

237 56 00 Duke (onboard): Huh?

237 56 01 Mattingly (Young in cm transcript): Okay.

237 56 04 Mattingly (onboard): (Garble).

237 56 05 Duke (onboard): I'll tell you what I saw.

237 56 06 Mattingly (onboard): Okay. I'm coming (garble) Maybe I'm just getting . ..

237 56 10 Hartsfield: Later on in the day, we're gonna do some of these gainsteps, but we'll call them real time.

237 56 13 Duke (onboard): Huh?

237 56 14 Mattingly (onboard): (Garble) be another (garble) difficult.

237 56 17 Young (onboard): Okay ...

237 56 18 Duke (onboard): Oh, sure.

237 56 18 Mattingly (Young in CM transcript): Okay. We'll be awaiting your call.

237 56 20 Duke (onboard): But in the - in the - in the small little model of the 12 kilometer ...

237 56 24 Mattingly (Young in CM transcript): Or where else would we be?

237 56 27 Hartsfield: (Laughter) Roger.

Public Affairs Officer: This is Apollo Control, Houston; at 262 hours, 43 minutes Ground Elapsed Time. Apollo 16 now 124,694 nautical miles away from the Earth. Velocity now shows 5,038 feet per second.

237 56 26 Duke (onboard): ...the 12 kilometers that we visited, that is - that is a hypothesis that could - could work. That might not hold true for anywhere else but right there.

237 56 37 Mattingly (onboard): (Garble) hypothesis? You have to prove it if it's a hypothesis.

237 56 40 Duke (onboard): I know - I'm saying - it could be totally wrong that - and it's not even a hypothesis, it's a - an impression I have right now - that - and the impression could be proved totally wrong when they look at the rocks.

237 57 00 Mattingly (onboard): (Garble).

237 57 05 Duke (onboard): Observations in the rocks we picked up.

237 57 07 Mattingly (onboard): (Garble).

237 57 10 Duke (onboard): That the rocks in that South Ray ejecta are the same as the rocks at North Ray. So at least to the depth that they penetrated, there was some crystalline rocks at least to those depths - at those depths. The rocks came out, and there they are; they got to come from somewhere . And then, covering this - all this, and probably ...

237 57 31 Young (onboard): (Yawn)

237 57 32 Duke (onboard): ...predating, at least predating the - the - the event, the South Ray event, there was a volcanic episode of - of - of pretty pyroclastic nature that created a tuff breccia, and the clasts in the brec - in the tuff are the same as the rocks - as the crystalline rocks that you brought back from the secondary craters.

237 58 00 Mattingly (onboard): (Garble) hypothesis (Garble).

237 58 0h Young (onboard): Well, I think they've oversimplified the thing.

237 58 06 Duke (onboard): They do.

237 58 07 Young (onboard): The first thing, I think, is that probably that whole area was a big impact thing to start with, see? So then on top of that then happens all these things that Charlie's talking about, and then after that - a while later - happens the Imbrium event.

237 58 21 Duke (onboard): Yeah.

237 58 22 Young (onboard): And I don't think the Imbrium event had beans to do with what went on there. Because I don't think any of those rocks look anything like what they - those guys got up on the -

237 58 30 Duke (onboard): Me either. The Fra Mauro ...

237 58 32 Young (onboard): Fra Mauro or anything.

237 58 33 Duke (onboard): The rocks are totally different. None of them - they don't - we did not see one rock that looked like any of the other Apollo rocks, not one. Not one!

237 58 58 Young (onboard): We'll tell them that today at the press conference.

237 59 03 Duke (onboard): Well, I can say it in truths. I don't think.

237 59 06 Young (onboard): I don't, either.

237 59 07 Hartsfield: Ken, sometime when it's convenient - anytime you can get to it, we'd like to get a film status.

237 59 16 Young (onboard): They want a film status, Ken, anytime you can get to it.

237 59 26 Mattingly (onboard): (Garble).

237 59 29 Duke: Okay, Henry. He'll - Thank you.

237 59 34 Hartsfield: Roger. No rush on that, Charlie. Just whenever you work it in.

237 59 39 Young (Duke in CM transcript): Okay. You mean you want him to pull out every magazine and see how it's doing, or what do you want?

237 59 51 Hartsfield: Let me see how detailed they want it.

237 59 56 Young: And ask why: I mean, because we got some of these things stowed where you wouldn't believe. It's not gonna be too easy. We're gonna have to take the entry stowage apart to get at them.

238 00 20 Hartsfield: We don't want to out-stow anything. If he - If he's got it written down up there somewhere, that will be satisfactory; whatever his records show. If he doesn't, let's just forget about it.

238 00 30 Young: Okay. Understand.

238 00 31 Mattingly: Hey, Henry?

238 00 32 Hartsfield: Roger.

238 00 33 Mattingly: What are you looking for? What are you looking for, Henry? Maybe I can - I can help you. If you you're looking for mags that have film on them, I can - that might not be so hard to track down, but - do you just want to know what pictures we took?

238 01 00 Hartsfield: We got an antenna switch coming.

238 01 54 Hartsfield: Ken, I haven't gotten a real satisfactory answer on this. Apparently, this is for the Photolab. They just kind of want to got - get an idea of your usage. But the way it looks to me, I wouldn't - I wouldn't do anything special, unless you got it written down there somewhere.

238 02 10 Young: Okay, Henry. You can tell the Photolab that they're in real trouble, because they're going to be developing film for a long time.

238 02 22 Hartsfield: Okay.

238 02 41 Mattingly: Most of the 70s are - are - are already exposed, with maybe like 10 frames remaining on each or something. And the 16s, I don't really know what their status is. We'd have to go through and look at each mag. It's my impression that most of them are only partially used. There's about four that I can think of offhand are empty. And we'll know all that as soon as we get out of the ship.

238 03 14 Hartsfield: Okay. That's good enough, Ken.

238 03 18 Mattingly: Thank you, sir.

238 05 10 Hartsfield: Charlie, your better half says she would like for you to bring your mustache home with you.

238 05 19 Duke: I'm not gonna do it.

238 05 22 Hartsfield: Roger.

238 05 36 Young: Henry, what she said was - she said was she'd be tickled if Charlie brought his mustache home with him.

238 05 41 Hartsfield: Roger. (Laughter)

238 05 57 Duke: I can't wait to shave this off. We've had a little failure with this shaving gear and that's our prob - that's been our problem.

238 06 08 Hartsfield: Roger. Understand.

238 07 36 Young: Hey, Henry. I got the biomed hooked up now. Ask the friends on your left there how it looks.

238 07 43 Hartsfield: Okay. Looks good.

238 07 50 Young: Okay. How does it feel?

238 07 54 Hartsfield: (Laughter)

Public Affairs Officer: This is Apollo Control, Houston; at 262 hours, 55 minutes Ground Elapsed Time. Apollo 16 now 124 098 nautical miles away from the Earth. Velocity now reads 5,055 feet per second.

238 11 43 Mattingly: Hey, Henry.

238 11 44 Hartsfield: Yes, sir.

238 11 48 Mattingly: Can you tell us if we have the tape recorder running on board in a forward direction, so we can record on it. And looks like we need about an hour's worth of tape. Or are they in a playback cycle, or what are they doing?

238 12 04 Hartsfield: Okay, I'll check it, Ken.

238 12 07 Mattingly: Thank you.

238 12 09 Young: We're gonna start checking these light flashes.

238 12 12 Hartsfield: Okay. The Tape Recorder is in Rewind and as soon as we get an antenna switch, we'll start it off for you.

238 12 19 Mattingly: Okay. I still think these things are manufactured by the same guy that makes the emperor's clothes.

238 12 28 Hartsfield: (Laughter)

238 12 31 Duke: Don't believe it. They're everywhere! They're everywhere!

238 13 03 Duke (onboard): (Garble) doing that?

238 13 04 Young (onboard): (Garble) medical kit back. I'm gonna get the salve out of there and give my arm another dose.

238 13 08 Duke (onboard): How's it looking? Staph got to it yet?

238 13 11 Young (onboard): It's just - it ain't gonna - it ain't gonna get infected.

238 13 16 Mattingly (onboard): In an environ ...

238 13 17 Young (onboard): It's already infected.

238 13 18 Mattingly (onboard): In an environment like this?

238 13 19 Duke (onboard): It already is infected.

238 13 20 Young (onboard): I would expect the staph germs run around here two or three times a day, just taking a big bite out of it (laughter).

238 l3 32 Mattingly (onboard): That stuff's supposed to be pretty good, isn't it?

238 13 37 Duke (onboard): No, it ain't worth a darn.

238 13 38 Young (onboard): (Garble).

238 13 39 Duke (onboard): It ain't worth it.

238 13 40 Mattingly (onboard): Sure?

238 13 4l Duke (onboard): Yeah. All it is is some mild antiseptic. That's all it is.

238 13 47 Mattingly (onboard): Oh, (garble) local antibiotics get absorbed in the tissues and all that stuff.

238 l3 58 Duke (onboard): (Garble)?

238 14 00 Hartsfield: 16, your Tape Recorder is running Forward.

238 14 06 Mattingly: Thank you, Henry.

238 14 45 Young (onboard): Watch your foot there, Charlie.

238 14 47 Duke (onboard): Wait a minute, John. You got to put this back in there.

238 14 51 Young (onboard): Oh.

238 14 53 Duke (onboard): There you go.

238 14 54 Young (onboard): I think I'm losing my mind.

238 14 59 Mattingly (onboard): Houston. We're having to take drastic measures. Our commander has lost his mind.

238 15 11 Duke (onboard): (Garble) ...

238 15 13 Young (onboard): Take over the ship and go to Mars.

238 15 14 Duke (onboard): I'm good at this. Turn off the lights (laughter).

238 15 20 Young (onboard): The only reason we're doing this experiment is because Charlie excels at it (laughter).

238 15 24 Mattingly (onboard): My feelings are hurt. I can see them, too, a little.

238 15 28 Young (onboard): Man, I don't - I have been looking for those darn things. Maybe I'm looking too hard or something. I can't see anything. It's really frustrating.

[End of CM Transcript]

238 19 26 Hartsfield: 16, Houston. The light-flash folks request that if you see one of those things and - identify yourself when you call the mark so they - if the tape is bad, they'll be able to still tell who made the mark.

238 19 50 Mattingly: Okay.

238 41 06 Hartsfield: Apollo 16, Houston. The PIs say that you should be calling your Marks also down on the loop - on the air to ground.

238 41 45 Mattingly: ...I think Charlie's seen about seven or eight.

238 41 49 Hartsfield: Roger.

238 42 03 Young: They're just not coming out too well today, Hank.

238 42 06 Duke: Mark. There's one, Henry, for you - right eye - that's Duke. On the bottom - bottom of the right eye is a little bright dot.

238 42 17 Hartsfield: Roger.

238 42 20 Young: Mark. In the outboard of the left eye - Young. A dot flashed that terminated toward the center.

Public Affairs Officer: This is Apollo Control, Houston; at 263 hours, 30 minutes [238:43] Ground Elapsed Time. You heard that report that both Young and Duke have seen the light flash. The crew of Apollo 16 now going through the light flash observations experiment. This is a controlled experiment during the Trans-Earth coast in an effort to correlate light flashes to incident primary cosmic rays. Ken Mattingly, is wearing an emulsion plate device on his head called the Apollo Light Flash Moving Emulsion Detector.

238 44 10 Young: Mark. Soft photoflash in the center of the - center right of the right eye - Young.

Public Affairs Officer: Young and Duke wear eye shields.

238 44 30 Young: Mark. Dot in the upper left center of the left eye - Young.

Public Affairs Officer: We're at 263 hours, 31 minutes [238:44] Ground Elapsed Time. Apollo 16 now 122,335 nautical miles away from the Earth.

238 45 50 Young: Mark. Light streak in the lower part of the left eye - Young.

238 51 34 Duke: Mark. Duke - right eye, upper center - a thin white streak.

238 52 21 Young: Mark. Young - and in the upper right eye, a couple of streaks from - looked like they were going from left to right - out at - about 2 o'clock out.

238 53 39 Duke: Mark. Duke - bright dot, lower center, right eye.

238 55 30 Duke: Mark. Duke - right eye, upper outboard, a bright dot.

Public Affairs Officer: This is Apollo Control, Houston; at 263 hours, 42 minutes [238:55] Ground Elapsed Time. You hear the crew of Apollo 16 continuing with the flashing light experiment, and we now show the spacecraft at 121,761 nautical miles away from the Earth, and travelling at a speed of 5,121 feet per second. Continuing to monitor, this is Apollo Control, Houston.

238 56 47 Duke: Mark. Duke - upper right eye - right eye, upper center, a bright dot.

238 57 14 Duke: Mark. Bright dot, very center, right eye - Duke.

238 58 27 Duke: Mark. Duke - upper right eye - a fuzzy flash.

238 58 43 Young: Mark. Young - a streak at the top of the right center of the right eye, going from - going out the top.

239 00 26 Duke: Okay, Hank. The first part of that - I was looking out the plus-X. Now I'm turning over on my right side and I'm looking out the Y-axis now - out Window 5. And I'll see if that's going to make any difference.

239 00 48 Young: Okay, Hank. On the first part of mine, I was - first 30 minutes, I was right side up in the LEB with my head against the optics covers. And now I'm upside down in the LEB with my head against the optics covers to see if that makes any difference.

239 01 11 Hartsfield: Roger. Copy.

239 02 34 Duke: Mark. Faint white dot on the left eye, lower inboard - Duke.

239 06 28 Duke: Mark. Duke - lower right eye - a faint, fuzzy flash.

239 06 43 Young: Mark. Young - left eye - a streak going from top to 'bottom in the - in the outboard part of the left eye.

239 07 18 Duke: Mark. Duke - right eye, lower center - a bright dot.

239 08 43 Duke: Mark. Bright dot - upper right eye - Duke.

239 09 01 Duke: Mark. Left eye - bright dot - Duke - outboard.

239 10 07 Duke: Mark. Duke - a fuzzy flash in the upper left eye, simultaneously with a bright dot in the right eye.

239 11 28 Duke: Mark. Upper left eye - little faint dot. That was Duke.

239 14 20 Hartsfield: Apollo 16, Houston. We show your ALFMED period up.

239 14 27 Mattingly: Okay.

239 14 42 Hartsfield: And, 16, when you get ready to maneuver to this new attitude, if you don't have Bravo 1 enabled, your present jet configuration is okay.

239 14 56 Mattingly: Okay, Hank. I'll check it.

239 15 06 Young: That new attitude I went to was great, Hank. I almost went to sleep.

239 15 11 Hartsfield: Roger. And I gather that ALFMED must be a pretty effective shield. I didn't hear Ken saying anything.

239 15 21 Young: He wasn't supposed to use it.

239 15 25 Duke: We already did that on the outbound leg.

239 15 27 Hartsfield: Oh, okay.

239 15 32 Duke: He was doing something, but it was all audible.

239 16 07 Young (onboard): (Garble), Ken.

239 16 08 Mattingly (onboard): Oh, yeah. I'll get it.

239 16 10 Duke (onboard): We ought to clean this. This hose has gotten filthy

239 16 15 Mattingly (onboard): What's filthy?

239 16 16 Duke (onboard): That hose - that inlet hose on my side ...

239 16 18 Young (onboard): (Garble) some - tape?

239 16 19 Duke (onboard): Need a piece of tape.

239 16 21 Young (onboard): I'll get it for you, Charlie, (Garble).

239 16 23 Duke (onboard): Okay.

239 16 24 Mattingly (onboard): You got the Flight Plan or something?

239 16 25 Duke (onboard): John's got it.

239 16 27 Young (onboard): Yeah, I got it. Here you go, Ken. Too-do-do-do.

239 16 33 Mattingly (onboard): And John's got a pencil, bet you.

239 16 34 Young (onboard): Yeah, I got the pencil you bet me. We ain't got too many pencils. I hope we can get back without too many more Flight Plan changes.

239 16 42 Mattingly (onboard): (Laughter)

239 16 52 Young (onboard): Shucks, I don't see the tape. There it is. We should have brought the tape over from the LM.

239 16 57 Mattingly (onboard): It's right down here.

239 16 58 Duke (onboard): I know it. I forgot it. Oh, (Garble).

239 17 07 Duke (onboard): Here you go, John.

239 17 11 Mattingly: Hank, what was the jet you wanted to have me turn off?

239 17 14 Young (onboard): B3?

239 17 14 Hartsfield: Roger. Bravo 1, so it won't fire in the SIM bay.

239 17 17 Mattingly (onboard): Bravo 1.

239 17 18 Hartsfield: ...If you used Bravo 2 and Delta 1 for roll, you'll be okay just to leave that configuration and maneuver on to the next attitude.

239 17 36 Mattingly: You want to use Bravo 2 and Delta 1. Is that affirmative?

239 17 41 Hartsfield: That's affirmative.

239 17 48 Young (onboard): When do we get to dump urine, man? I got to dump so bad I can taste it.

239 17 54 Duke (onboard): Why don't you go in that - squirt it in that white bag?

239 17 55 Young (onboard): Okay.

239 17 57 Duke (onboard): It's a while before we get to dump.

239 17 59 Young (onboard): I recall.

239 18 02 Mattingly: Okay, Hank. They - that's not the jet configuration they gave us this morning because I did have the SIM bay jets - No, I'll have to look up those jets I had this morning, but Bravo 1 was one of the ones I had turned on.

239 18 23 Hartsfield: Roger. We understand that, Ken. The reason is that when we stop the PTC the - we're - in the configuration you had, you'd probably use - you'd have to use Bravo 1 to stop it, and it would fire into the SIM bay. It probably never fired during the PTC.

239 18 44 Mattingly: Okay.

239 18 45 Mattingly (onboard): I see what you mean.

239 18 46 Duke (onboard): Boy, you have been frugal on the gas, Ken.

239 18 47 Mattingly (onboard): It ain't stopping. How come?

239 18 56 Young (onboard): What ain't stopping, Ken?

239 18 59 Mattingly (onboard): Oh, you can't do that. That's right.

239 19 25 Duke (onboard): Hey, we get to dump here in just a minute, John.

239 19 29 Young (onboard): What time?

239 19 30 Duke (onboard): In about 50 minutes.

239 19 36 Young (onboard): How nice.

239 20 33 Mattingly (onboard): That's gonna be minus 40 and Yaw 90.

239 20 37 Duke (onboard): On the high gain?

239 20 38 Mattingly (onboard): Yeah.

239 20 46 Duke (onboard): Wonder what we got.

239 20 50 Mattingly (onboard): It's Reacq.

239 20 53 Duke (onboard): From Reacq to Narrow.

239 20 56 Mattingly (onboard): Okay.

239 21 04 Crew: (Yawn).

239 21 08 Mattingly (onboard): Now, you went and changed dead band to 2 degrees in there (garble) ...

239 21 12 Duke (onboard): That's right, I did.

239 21 13 Mattingly (onboard): Oh.

239 21 14 Duke (onboard): For this. And I didn't know whether that - what that'd do - they said to change Noun 79 dead band to 2 degrees. I didn't know what number that was.

239 21 23 Mattingly (onboard): That's good. You did it right.

239 21 37 Young (onboard): When's the press conference? It's a long ways from now, isn't it - 4 hours?

239 21 40 Duke (onboard): (Yawn) Yeah.

239 21 42 Mattingly: Hank, this one you want to do is a normal PTC? Or do you want to use this one as a - as the enabled jet version.

[Break in CM transcript]

239 21 53 Hartsfield: Roger, Ken. We'd like to do it in that same procedure that - that Tony read to you this morning. And, for the next one at about 275:50, we'll go back to the regular procedures.

239 22 07 Mattingly: Okay. And you want to use the same jets that Tony read me this morning?

239 22 10 Hartsfield: Roger. And those, I guess, should be the ones you have enabled now.

239 22 20 Mattingly: Except I got - this morning I had all B/D Rolls enabled.

239 22 26 Hartsfield: Okay, we'd like to start up in single jet, which is what you have now.

239 22 38 Mattingly: Okay. I'll use the jet configuration I have now, then.

239 22 42 Hartsfield: Roger. And, I guess - did Tony read you the change that we wanted the 2-degree dead band?

239 22 49 Mattingly: Yes, sir.

239 22 50 Hartsfield: Okay.

239 22 52 Mattingly: And how about the rate? Now, he read me 0.3 this morning, and normally we do 0.42. I take it 0.3 is what you're really after.

239 23 03 Hartsfield: Let me double-check that one.

239 23 15 Hartsfield: Okay, 0.3 is the correct rate.

239 23 20 Mattingly: Okay.

239 23 34 Hartsfield: And, Ken, when we get to attitude, we'd just like to hold that before you start the P20, so we can dump the tape recorder.

239 23 42 Mattingly: Okay.

Public Affairs Officer: This is Apollo Control, Houston; at 264 hours, 12 minutes [239:25] Ground Elapsed Time. We now show Apollo 16 at 120,287 nautical miles away from the Earth [and] now travelling at a speed of 5,163 feet per second.

239 27 19 Hartsfield: Ken, we need to get the High Gain, and I guess we need you to do a Manual Roll about 30 degrees left.

239 27 29 Mattingly: Okay.

239 27 41 Hartsfield: And, in regard to the urine dump coming up, the doctors think they see a correlation between the urine dump times and the dump port temperature. So, just to see if this really works, and if it does work, we may be able to get rid of all of this recording stuff. We'd like for you to identify which bags you are dumping and give us a mark at start and the end of the dump.

239 28 10 Mattingly: Run that by one more time, please?

239 28 13 Young: Looks like you guys don't understand the problem, do you? I can't believe that. We all dumped the urine into the same bag.

239 28 24 Hartsfield: Okay, give us a start and stop.

239 28 26 Young: We been stowing - yeah, but, Hank, we're all dumping into the same big white bag and then that gets dumped over to the side. Is that what you want? A total volume from all three of us?

239 29 17 Young: Did you get my last, Henry?

239 29 20 Hartsfield: Roger. They still would like to know the start and stop times.

239 29 27 Mattingly: (Laughter) Be our guest.

239 29 29 Young: What do you - start and stop of what? You know, we let this thing purge, line out, and then we let it sit there until we're sure everything's all cleaned out - afterwards, to make sure we don't plug things up. I guess we can tell you when we do each step, but we don't really know when those bags are empty.

239 29 44 Hartsfield: Well, that would be my guess, also, but can you guess at it? Okay, if you can't, forget it.

239 29 55 Young: Okay.

239 30 24 Young: Okay, Henry. Here's what we've been doing with the urine.

239 30 50 Young: Is this attitude okay for you, Hank?

239 30 56 Hartsfield: Roger.

239 31 03 Hartsfield: John, could you repeat what you said. INCO cut the antenna off about the time you started?

239 31 25 Young: Houston, is this attitude okay for the High Gain?

239 31 27 Hartsfield: That's affirmative. It's a good attitude.

239 31 32 Young: Okay, now. Let me tell you what we've been doing with this stuff. We've been using the Gemini [?] bags and then dumping it into a big white bag. And it's all in there now, all mixed together, and nobody knows whose is whom's. And - and, furthermore, we don't know when we dump that big white bag when - We know when we start to do it, but we don't know whenever it finishes. Because you can't see the inside of the bag. You just don't have a feel for that. So, what you just do is you just let it run until you think you ought to quit and look and see if you've got particles on the outside. And even after you quit, there's still particles on the outside.

239 32 13 Hartsfield: Roger. Copy, John. Why don't we forget about that?

239 32 21 Young: Okay. I would be glad to do it, if I thought it would give you any data. But I can't see how it'll give you anything you could use.

239 32 30 Hartsfield: Okay, John. What we're trying to do is find some way to make the procedures a little cleaner on - on Apollo 17. So they think they can get some useful data out of this, and if you can just give us a mark when you start, maybe they, from the temperature curves, can tell just about when it ends. They got a - they're trying to get a calibration on how the temperature of the port changes during the dump.

239 33 01 Young: Yeah, but - are you sure that, for example, that we don't have at least thousands of chamber dumps that'll tell you the same thing?

239 33 22 Hartsfield: Okay. They said the chamber data is what got them looking at the possibility of doing this.

239 33 29 Young: Okay, Hank, I'll tell you what we'll do. We'll give you mark when we start and a mark when we stop.

239 33 36 Hartsfield: Thank you.

239 35 44 Young: Purge line heater, Houston - on, Houston.

239 35 48 Hartsfield: Roger; copy.

239 41 03 Hartsfield: 16, Houston. When you get ready to dump the waste water, we'd like to dump to 49 percent. That'll leave us enough for the Skylab contamination.

239 41 22 Mattingly: Okay, dump to 49 percent.

239 41 41 Hartsfield: 16, Houston. We can go ahead and start spinning up, but first we've got to load the Verb 49 with a current roll attitude and Pro going to attitude and then start the spinup. And for the spinup, we'd like to use Delta 2 in addition to the Jets you now have configured so we can get a couple of spinups, and then turn Delta 2 back off.

239 42 07 Mattingly: Okay, we add Delta 2 for the start and then turn it off.

239 42 11 Hartsfield: That's affirmative.

Public Affairs Officer: This is Apollo Control, Houston; at 264 hours, 31 minutes [239:44] Ground Elapsed Time. Apollo 16 now 119,365 nautical miles away from the Earth. Our velocity display now shows speed 5,190 feet per second. Continuing to monitor this is Apollo Control, Houston.

239 52 59 Hartsfield: Ken, I guess you've figured out the reason we got caught there is we can't load the Noun 79 in Option 2.

239 53 10 Mattingly: Yeah, I just figured that out, Hank. Is what I did there to fix it okay?

239 53 21 Hartsfield: Okay, you restarted it after going to Accel Command, is that right?

239 53 28 Mattingly: Yeah, I restarted it, then didn't mean to stop it, just kind of kept it going. Is that attitude looking all right or - I don't have any way of reading out where the dead band is centered now. Would you like for me to just stop and start all over again?

239 53 42 Hartsfield: Okay, we'll take a look at it.

239 54 04 Hartsfield: Okay, the - the center's only about a half a degree off from where we wanted it. So that's good.

239 54 16 Mattingly: Okay; thank you, Hank.

[CM Transcript restarts.]

239 57 04 Young (onboard): When's that old exercise period start?

239 57 06 Mattingly (onboard): I think next hour.

239 57 08 Young (onboard): Yeah. Hardly wait to get a hold of that Exer-Genie; I'm gonna tear it to pieces.

239 57 24 Young (onboard): Must be getting near the Earth; my sinuses are starting to bother me again.

239 57 37 Mattingly (onboard): How about let's do some water dumps.

239 57 40 Young (onboard): Hey, yeah. Can we do that now?

239 57 45 Mattingly (onboard): (Garble) It says we can purge the oxygen from the fuel cell, urine dump, waste water dump ...

239 57 52 Young (onboard): Okay, what you want to set on here? It's reading 65 now. We're supposed to purge to what, 49?

239 57 57 Mattingly (onboard): Forty-nine. So that's only 15 percent.

239 58 00 Young (onboard): Fifteen percent at 5 minutes?

239 58 02 Mattingly (onboard): Five percent a minute.

239 58 04 Young (onboard): Three minutes? You want to put 3 minutes - I'll put 2½ on there.

239 58 07 Mattingly (onboard): Yeah.

239 58 09 Young (onboard): Is it running? Times 10?

239 58 11 Mattingly (onboard): I think you need to - All righty.

239 58 19 Young (onboard): Okay.

239 58 20 Mattingly (onboard): And open her up.

239 58 36 Young (onboard): Okay, that's under way.

239 58 54 Young (onboard): Here, let me put your - your little bag in there.

239 58 58 Mattingly (onboard): Okay. Thank you. And let's see. I'll get a little oxygen purge going here.

239 59 08 Duke (onboard): What time does the urine dump start?

239 59 11 Young (onboard): Oh, flowing right now.

239 59 12 Mattingly (onboard): Let's wait until - let's do these things one at a time. They're gonna try to get something out of that. Let's at least give them a halfway chance.

239 59 19 Young (onboard): I don't want to give them a halfway chance. I don't think they deserve it, Ken. You're just being overly nice to them. You want to look out the window and see if you can do it, or -

239 59 29 Mattingly (onboard): Okay. Just a second, I'll - Sure will. Okay, I got the first oxygen under way.

239 59 41 Young (onboard): It's - it's raining!

239 59 46 Mattingly (onboard): Man, is it ever raining.

239 59 48 Young (onboard): Man, is it ever. We'll leave the window open; that'll be a clue something's going on out there.

239 59 53 Mattingly (onboard): (Singing) It's raining, it's pouring. Well, I need some music to dump urine by.

240 00 02 Young (onboard): Music to dump by; I was just gonna suggest that.

240 00 05 Mattingly (onboard): What kind of music is fitting, though?

240 00 08 Young (onboard): You might try the -

240 00 13 Mattingly (onboard): Oh, heck, I think it got knocked out on the - It did. That battery!

240 00 19 Young (onboard): Where do they keep those?

240 00 21 Mattingly (onboard): They go in a little bag. We finished that one, anyhow. They go in a little bag up here. I think they're in that far side with the little bitty Bull Durham sack.

240 00 32 Young (onboard): In here?

240 00 33 Mattingly (onboard): Yeah, I think so. The little drawstring in the top?

240 00 42 Young (onboard): Yep. Are these the new ones or the old ones? There you go.

240 00 49 Mattingly (onboard): I think we need another two minutes.

240 00 53 Young (onboard): The old ones have been thrown away, so we won't get them confused. Another 2 minutes to dump, right?

240 01 01 Mattingly (onboard): Yeah.

240 01 O4 Young (onboard): Going down to 60 percent now. Only supposed to go to 49, didn't you say?

240 01 10 Mattingly (onboard): Yeah. What kind of music is a good music to dump by?

240 01 15 Young (onboard): (Singing) Music to dump by - How's your oxygen purge going?

240 01 29 Mattingly (onboard): It's about time for the first one to come off.

240 01 31 Young (onboard): Okay.

240 01 33 Mattingly (onboard): Put the second one on.

240 01 36 Young (onboard): Put the second one on. That's oxygen, right?

240 01 39 Mattingly (onboard): Right. Okay.

240 01 4l Young (onboard): It's on.

240 01 42 Mattingly (onboard): Okay.

240 01 51 Mattingly (onboard): Think this is - (garble) popular music sandwiched on the end (garble) where it is.

240 01 58 Young (onboard): If they'd have had the same problems we had on Apollo 8 - Borman was going out of his mind - he'd have shot himself.

240 02 04 Mattingly (onboard): I don't really blame him.

240 02 04 Hartsfield: 16, Houston. We show you 55 percent on the waste tank. I'll give you a call at 50.

240 02 13 Young: We're watching it, Henry.

240 02 16 Hartsfield: Okay.

240 02 18 Young: That ain't good enough from past experience, is what you're saying?

240 02 22 Hartsfield: I'm not saying that at all, John; just thought I would help if I could.

240 02 26 Young: Okay. You are, Hank. I'm just teasing.

240 02 48 Young (onboard): Looks like 49 to me.

240 02 49 Mattingly (onboard): Okay, turn it off.

240 02 50 Young: Looks like 49 to us.

240 02 51 Young (onboard): Go; don't talk about it.

240 02 53 Hartsfield: Roger. We show about 50, now.

240 03 00 Young (onboard): I can't find the switch.

240 03 03 Hartsfield: Mark; 50 percent.

240 03 08 Mattingly (onboard): Got it? John?

240 03 11 Young: Okay, she's shut down.

240 03 18 Duke (onboard): Got that (Garble).

240 03 20 Mattingly (onboard): No, not yet. It's only one minute. Okay, there's two minutes. Off.

240 03 33 Young (onboard): Okay.

240 03 34 Mattingly (onboard): Number 3. Go.

240 03 35 Young (onboard): (Garble).

240 03 50 Mattingly (onboard): That's really a beautiful sight, though.

240 03 51 Young (onboard): It really is.

240 03 53 Mattingly (onboard): You know what that reminds me of? You know these things that people have (garble) these little desk things and all with the - the fluid and a whole bunch of ...

240 04 01 Young (onboard): Looks to me like ...

240 04 02 Mattingly (onboard): ...particles in it that looks like snow, and, you can turn it over and it stirs it all up? That's just what that looks like to me.

240 04 07 Young (onboard): Looks to me like snowing at night in bright light.

240 04 10 Mattingly (onboard): Yeah. It's really beautiful. I hope those - those stereo pictures might show that. I hope so. I really want to do that part of the experiment right today, because I think that would be a beautiful picture to show. I guess we can get on with the urine dump.

240 04 36 Duke (onboard): I'll get out of (garble) I got it.

240 04 41 Mattingly (onboard): Why don't you dump my little bag first? You need a mark on that?

240 04 53 Duke (onboard): What do you want to do, Ken, first?

240 04 55 Mattingly (onboard): Dump my little bag first.

[End of CM Transcript.]

240 06 30 Young: Hank, we're gonna start, and we're gonna give you something in a little bag first, and I'll give a mark when we start it and when we stop it and when I see particles start to slow down, and then we'll go emptying the bigger bag.

240 06 43 Hartsfield: Roger; copy.

240 06 46 Young: Okay, stand by.

240 06 47 Young: Mark. It's started.

240 06 58 Young: Okay, the bag's empty and I don't see anything out the side, yet. It's started out the side, now. Okay, we're leaving the bag on purge.

240 07 14 Hartsfield: Roger.

240 07 36 Young: Okay, the particles are starting to slow down, but they spurt every now and then. Man, there's a big blast.

240 08 13 Hartsfield: Ken, do you have an estimate of the quantity in the little bag?

240 08 22 Young: No, there's no way to get that (laughter).

240 08 25 Mattingly: You're supposed to give us that.

240 08 26 Young: That's what you're doing. You're supposed to tell us that (laughter).

240 08 30 Mattingly: It's whatever 5 psi does through a 1/20,000 hole that's modified by ice.

240 08 38 Hartsfield: Roger (laughter).

240 08 48 Young: Okay, we've got the bag off. We're getting ready to start another one, and most of the particles have stopped.

240 09 23 Young: Okay, we're running another bag.

240 09 53 Young: Okay, that bag's empty.

240 09 56 Hartsfield: Roger.

240 10 41 Young: There's another bag started.

240 10 45 Hartsfield: Roger.

240 10 58 Young: That one is empty -

240 10 59 Young: Mark.

240 12 56 Mattingly: Okay, we're starting on our big bag.

240 12 59 Hartsfield: Roger.

240 13 06 Young: And it's dumping now.

240 13 07 Mattingly: Okay.

240 14 30 Mattingly: Well, it looks like our big bag is empty somewhere in here.

240 14 36 Hartsfield: Roger. Copy, Ken.

240 15 46 Young: You know, Houston, we think one of the problems you're gonna have with this kind of a - a measuring thing is how - how clogged up your filters are. Like we don't think it's dumping as much right now as it was when it started because we think the filter's getting clogged.

240 16 07 Hartsfield: That's a good point, John.

[Start of CM Transcript.]

240 16 29 Young (onboard): ...(garble) these circuit breakers (garble) ...

240 16 29 Hartsfield: We also see that if we're gonna do sequential dumping, we're gonna have to wait between the dumps, you know, to allow the nozzle - the temperature to stabilize.

240 16 40 Young: That's affirmative.

240 17 11 Duke (onboard): (Garble) switch to off, then (Garble).

240 17 15 Young (Mattingly in CM transcript): We're gonna turn the dump valve off and change filters.

240 17 22 Hartsfield: Roger.

240 17 30 Duke (onboard): Okay, back to dump.

240 17 31 Mattingly (onboard): Going back to dump.

240 17 34 Duke (onboard): It's at 50 now.

240 17 37 Young (onboard): Yeah, it doesn't seem to be making much difference, Charlie. In fact, that's good to hear. When you went back to dump, it - it got pretty good.

240 17 45 Mattingly (onboard): Yeah, but it's not dumping like it was officially, you know, that big range.

240 17 49 Young (onboard): Yeah, well, that's a function of Sun angle.

240 17 52 Mattingly (onboard): Okay. Maybe that's it. The error - that's a function of Sun angle on the (garble) Okay. We'll buy that. You know, I was surprised how little stuff there was on that urine bottle, when I was out there .'

240 18 05 Young (onboard): Oh, yeah. We took pictures of it.

240 18 07 Mattingly (onboard): No, it was up in (garble) ...

240 18 08 Duke (onboard): (Garble) another bag (Garble).

240 18 10 Young: Okay, we started on another bag.

Public Affairs Officer: This is Apollo Control, Houston; at 265 hours and 5 minutes [240:18] Ground Elapsed Time. With these timed waste water dumps the ground is trying to calibrate in the - calibrate difference in temperature on the urine dump nozzle with the volume of fluid dumped. This conceivably could aid in the procedures in acquiring medical data for Apollo 17. It is questionable at this point if the data will correlate. We're at 265 hours, 6 minutes [240:19] Ground Elapsed Time. We show Apollo 16 at a distance of 117,608 nautical miles away from the Earth and travelling at a speed of 5,242 feet per second. This is Apollo Control, Houston.

240 18 26 Young: Bag's empty.

240 18 16 Mattingly (onboard): Oh, hey, there's one that'll look good, the dark shadow. You can see a lot more.

240 18 19 Young (onboard): Yeah, you can see a lot.

240 18 21 Mattingly (onboard): We're still losing (garble) ...

240 18 23 Duke (onboard): Bag's empty.

240 18 26 Mattingly (onboard): Bag's empty.

240 18 41 Mattingly (onboard): Maybe that's what we should have done before the EVA, Charlie, was to have a big water dump, so it wouldn't have looked so black.

240 18 48 Young (onboard): (Laughter) Well, I'll put a little water in your (garble) (laughter).

240 18 56 Mattingly (onboard): If the headshrinks would like to listen to that, that way we wouldn't be scared.

240 19 00 Young (onboard): That's right (laughter). I'm proud to hear you guys were a little nervous about something around here. I thought y'all were completely fearless there for a while.

240 19 12 Mattingly (onboard): I've had more high heart rates in the last two weeks than I have in my whole life.

240 19 18 Young (onboard): Pretty exciting business.

240 19 21 Mattingly (onboard): The thing that galls me about these shrinks and everybody else is - Just like the way they tackle zero g in the body. Instead of fighting the thing and trying to make you live in a protected environment, you ought to learn to live in the environment you're in.

240 19 34 Young (onboard): Yeah.

240 19 36 Mattingly (onboard): Let man adapt to zero g. Quit trying to force his body to stay in one-g condition, because it isn't gonna work.

240 19 45 Young (onboard): But if you provide him with one g, it ain't gonna work. I've been trying to tell them that. I told them, listen, if you want a guy to stay healthy in zero g that can - so he can hack it when he gets back, you gotta give him that one-g feel.

240 19 55 Mattingly (onboard): Right. And there's no future in that. That negates all the reasons for going into zero g.

240 20 00 Young (onboard): Well, and there's - you know - there's places on a spacecraft you could make it on, where you could put a - you could - you could put some (garble) ...

240 20 07 Mattingly (onboard): Yeah, but it's not productive. You'd have to spend 6 hours, 8 hours a day doing that.

240 20 12 Young (onboard): You'd have to spend a lot of time in your zero ...

240 20 15 Mattingly (onboard): Well. Just - Just getting adapted to one g. (Laughter) You know, who - who needs it? I bet you the old bod is gonna taper off here and settle down and be just happy as a clam. So all it means is when you come home, you're gonna be kind of like a vegetable for a while, if it gets real bad.

240 20 30 Young (onboard): Yeah.

240 20 32 Mattingly (onboard): And you just learn to live with that. The only place I see a hazard is in recovery. If you had to really exert yourself ...

240 20 40 Young (onboard): Then that's really what we'd do, you watch.

240 20 43 Mattingly (onboard): I think I'd find a way to do that (laughter).

240 20 46 Young (onboard): You watch. You may have the opportunity tomorrow or the next day.

240 20 50 Mattingly (onboard): That's right.

240 20 54 Young (onboard): Yeah, recovery is just a different environment. We do have not much of it.

240 21 00 Duke (onboard): What do you mean, John?

240 21 02 Young (onboard): I mean, once you get in the ship, you're in danger of sinking. (Laughter) That's what I mean, Charlie.

240 21 07 Duke (onboard): You're what? You're in danger of sinking? Oh. I tell you, I ...

240 21 11 Young (onboard): You don't have to worry about space, but you've got to worry about swimming.

240 21 15 Mattingly (onboard): Yeah, I - I ain't so impressed with - I ain't going to be breathing easy until my fanny is on that ship.

240 21 19 Young (onboard): I ain't either. I never have been impressed by the way those guys pick you out of the water.

240 21 24 Mattingly (onboard): Well, I - I'll actually feel pretty good when they get a collar around this boat.

240 21 29 Young (onboard): Yeah, me too.

240 21 31 Mattingly (onboard): Until they get a collar around this thing, I ain't going to be very comfortable, because my experiences with the Stable II egress from this son of a gun have always been bad (laughter).

240 21 41 Young (onboard): Yeah.

240 21 49 Mattingly (onboard): That's so pretty. That's just beautiful. Somebody would think you're nuts if you said there's nothing prettier than urine dumps. (Laughter)

240 22 00 Young (onboard): They're going to wonder why we have a million pictures of those (garble) just fabulous.

240 22 05 Mattingly (onboard): The problem is, people have been setting focuses wrong, for one thing. What - what is the proper intensity to set this thing? I think these particles are real bright.

240 22 14 Young (onboard): They are.

240 22 19 Mattingly (onboard): You keep a focus setting very close.

240 22 23 Young (onboard): Yeah.

240 22 26 Mattingly (onboard): I wonder if - No, our TV just doesn't have the resolution to show that kind of stuff. It's a shame.

240 22 34 Duke (onboard): Do we have another eat period before TV?

240 22 37 Young (onboard): Yeah.

240 22 40 Mattingly (onboard): About time for me to dump my bag down there?

240 22 43 Duke (onboard): Oh, yeah; just a minute.

240 22 46 Mattingly (onboard): I don't want to ask you to do that, because it - because it's kind of Rube Goldberg.

240 22 50 Young (onboard): Dumping water?

240 22 51 Mattingly (onboard): Yeah. Let's turn the heaters off, okay?

240 22 58 Young (onboard): I don't want the - You want me to turn them off now, right?

240 23 01 Mattingly (onboard): Yeah.

240 23 02 Young (onboard): Okay.

240 23 04 Mattingly (onboard): Now you can stop and do the hydrogen purge.

240 23 05 Young (onboard): You mean really stop, and ...

240 23 06 Mattingly (onboard): (Garble) stop (garble) nominal. (Laughter) Okay.

240 23 11 Young (onboard): Where's the Exer-Genie?

240 23 13 Mattingly (onboard): It's in my TSB.

240 23 15 Young (onboard): Is it still, huh?

240 23 18 Mattingly (onboard): Yeah. I used it several times when I was solo. Finally worked out a pretty good routine. But I have absolutely no confidence (laughter) in those guys, because they'll let you do anything ...

240 23 30 Young (onboard): ISS light.

240 23 32 Mattingly (onboard): Could you cut - No. Okay. Okay.

240 23 44 Duke (onboard): Temporary ISS?

240 23 45 Young (onboard): Right.

240 23 46 Mattingly (onboard): 37777.

240 23 47 Young (onboard): CDU failed.

240 23 50 Mattingly (onboard): Okay.

240 23 51 Young: Okay, Houston, we got an ISS light and a 37777.

240 23 59 Hartsfield: Roger, understand. Stand by.

240 24 03 Young: Okay, the eight ball didn't move. That's the ICDU ("a CDU" in CM transcript) fail light is what it is.

240 24 12 Hartsfield: Okay, just stand by. We're looking at it.

240 24 13 Mattingly (onboard): 82, that's good. 130, that's good (garble) Okay, Noun 20s all look pretty good.

240 24 20 Young: Okay, the Noun 20s all look pretty good ...

240 24 22 Mattingly: ...a ...

240 24 23 Young: Yeah, ...is okay.

240 24 33 Mattingly (onboard): See if you hit that switch button accidentally.

240 24 35 Young (onboard): It's there.

240 24 41 Young: Okay, no switches were being touched at the time.

240 24 45 Duke (onboard): Must have been a glitch, huh? One of the glitches?

240 24 49 Mattingly (onboard): I'm glad it wasn't the middle gimbal, for a change.

240 24 51 Duke (onboard): What gimbal was it?

240 24 53 Mattingly (onboard): You can't tell.

240 24 57 Duke (onboard): Are we in att hold?

240 24 58 Mattingly (onboard): I am now.

240 24 58 Hartsfield: Okay, John. We saw the same thing you did and everything looks good; we're talking it over now.

240 24 59 Young (onboard): Gonna reset ...

240 25 05 Young (onboard): Want me to repeat that program alarm?

240 25 10 Young: Okay, program alarm reset.

240 25 14 Hartsfield: Roger.

240 25 21 Mattingly (onboard): (Laughter) Oh.

240 25 25 Young: ICDU ("A CDU"?) fail(ed?) transient, huh?

240 25 28 Mattingly (onboard): Well, let's not outguess it. We did that once, maybe. Maybe all our flap was for naught. Maybe we ought to (garble) (Laughter) The nice thing about this, John, is that with the CDUs out, we can still do a perfectly good entry.

240 25 41 Hartsfield: Apollo 16, Houston. We'd like for you to go through mal procedure G&N, Number 6 on page 28.

240 25 47 Young (onboard): You'll have to gimbal.

240 25 49 Mattingly (onboard): That's right.

240 25 50 Duke (onboard): With what?

240 25 51 Mattingly (onboard): G&N controlled entry.

240 25 52 Duke (onboard): You can?

240 28 56 Mattingly: Okay, stand by.

[ or ]

240 25 53 Mattingly (onboard): I sure can.

240 25 54 Duke (onboard): Good.

240 25 55 Young (onboard): He can do it with G&N controls.

240 25 56 Duke (onboard): How do you do that?

240 25 57 Mattingly (onboard): CDUs only talk to the computer.

240 25 58 Duke (onboard): Yeah.

240 25 59 Mattingly (onboard): They don't talk to the eight ball. And it - it thinks inertially. The platform just sits there and it does its thing, and it takes those accelerometers and integrates them and says, man, you need to go a little long. And if you needed to go long, you ought to have 112 degrees bank, and we just roll 112 and we'll plop it right in the same place the computer ...

240 26 16 Young (onboard): You'd have to adapt it.

240 26 17 Mattingly (onboard): Yeah. But it's got the same accuracy that the G&N has.

240 26 25 Young (onboard): We already found that out, didn't we?

240 26 27 Duke (onboard): I hate to tell you, but that brought on a "Shhh."

240 26 30 Crew: (Laughter)

240 26 33 Young (onboard): We'd better hurry. We got to give a TV show in ...

240 26 35 Mattingly (onboard): (Laughter)

240 26 37 Young (onboard): ...in 3 hours.

240 26 38 Duke (onboard): Three hours?

240 26 41 Mattingly (onboard): Yeah, thanks.

240 26 43 Duke (onboard): Do you want to dump your stuff down here, Ken?

240 26 45 Mattingly (onboard): Yeah, I guess.

240 26 46 Duke (onboard): Or do you want me to do it?

240 26 48 Mattingly (onboard): Let me stop and take a second look. That sure got my attention. I thought John was playing games ...

240 26 57 Duke (onboard): I turned around and looked at that, and I saw the PGNS light and the ISS light on down there.

240 27 05 Mattingly (onboard): Well, at this point, I feel pretty comfortable even without the PGNS. Because ain't nobody going to No-Go entry.

240 27 15 Young (onboard): That's for sure.

240 27 16 Mattingly (onboard): At least not up my watch.

240 27 18 Duke (onboard): I'd sure like - like to have that guidance working, though.

240 27 22 Mattingly (onboard): Well, got to have a little stick time.

240 27 28 Duke (onboard): It's a mighty big ocean.

240 27 29 Mattingly (onboard): (Laughter) I would like for it to come in automatically, too, Charlie; don't worry. My desire to be a hero does not mean I want to fly manually, just to prove you can do it.

240 27 42 Young (onboard): Now, Ken, you can do it. And I want you to prove it. (Laughter)

240 27 46 Mattingly (onboard): We will - if we need to, we will put it down right there, but I'd just as soon go automatic. I believe in computers.

240 27 54 Young (onboard): Yeah, I believe in computers, too.

240 27 57 Duke (onboard): That - that warning light was like going in the gym, Ken. (Laughter) Automatic constipation reliever (laughter).

240 28 07 Mattingly (onboard): Man, I'll tell you, the way I've been - the way I've been having to go lately (laughter). I'm really getting worried; if I were in the gym now, I would never stop.

240 28 16 Duke (onboard): Are you going to dump that thing through a filter and everything, Ken?

240 28 19 Mattingly (onboard): No. I'm going to dump it through the little filter.

240 28 22 Young (onboard): Okay.

240 28 23 Mattingly (onboard): I got to use the other end of that big filter ...

240 28 25 Duke (onboard): Close it.

240 28 26 Mattingly (onboard): ...of the urine hose here.

240 28 31 Young (onboard): Now promise me you're not going to clog up the urine tube. You ain't gonna promise me that, are you? (Laughter)

240 28 38 Duke (onboard): John?

240 28 40 Young (onboard): Yeah?

240 28 41 Duke (onboard): This is the last dump anyway.

240 28 43 Hartsfield: (Garble) ...

240 28 44 Mattingly (onboard): Have - have - ask him to hold on.

240 28 47 Hartsfield: ...(Garble).

240 28 50 Mattingly (onboard): Ask him to hold on and we'll be there. And the Mal Procedures are up there in the little (garble) box.

240 28 55 Duke (onboard): Okay. Stand by.

240 28 58 Mattingly (onboard): That - they're in that box that's so hard to get to, Charlie.

240 29 00 Duke (onboard): Yeah, I know.

240 29 01 Mattingly (onboard): That's normal. Gosh. Who turned the lights off? We got a burned out light in one of the pumps down here. Let's see, scissors. Hold that for a second.

240 29 17 Duke (onboard): Can you reach it?

240 29 21 Young (onboard): What could that be about?

240 29 25 Mattingly (onboard): Could what be about? The first thing I'd do is run a P52 and see if it knows where it is.

240 29 37 Young (onboard): No, it's a - The REFSMMAT flag is still set.

240 29 44 Mattingly (onboard): We can check all those ...

240 29 46 Young (onboard): The angles are good; it's got to know where it is, doesn't it? Better just keep your eye on that flag ...

240 29 51 Duke (onboard): Yeah, you - you could ...

240 29 52 Young (onboard): ...auto - auto transient wouldn't kill the REFSMMAT flag, would it?

240 29 56 Mattingly (onboard): Why don't we just go through this procedure and see what it says.

240 00 29 57 Young (onboard): Okay.

240 29 58 Mattingly (onboard): Let me take care of all those things in an orderly, thought-out fashion.

240 30 02 Young (onboard): Yeah, okay. Why don't I just move over here, and...

240 30 06 Mattingly (onboard): How's the dump looking?

240 30 11 Young (onboard): Still dumping.

240 30 14 Mattingly (onboard): Man, on the - Look at that I Look at that!

240 30 16 Young (onboard): You're dumping like crazy.

240 30 18 Mattingly (onboard): It worked.

240 30 19 Young (onboard): There it goes again.

240 30 20 Mattingly (onboard): Okay, we're in SCS mode. It doesn't matter.

240 30 25 Young (onboard): Watch it. Okay, we just had the program alarm again.

240 30 36 Mattingly (onboard): (Garble) first and two.

240 30 47 Duke (onboard): Here you go, Ken.

240 30 50 Mattingly (onboard): (Garble).

240 30 51 Duke (onboard): Here you go, John.

240 30 52 Young (onboard): Okay, I'll get it in a second. I got that purge ...

240 30 55 Mattingly (onboard): Again?

240 30 56 Duke (onboard): Yeah.

240 31 01 Young (onboard): Drive us crazy.

240 31 02 Mattingly (onboard): Well, if it's a bit failure, we can avoid that by going around it. Let me get in there and work on that thing for a moment.

240 31 16 Mattingly (onboard): Okay, I'm turning this thing off and it's not - the hose isn't hooked up to anything, Charlie.

240 31 21 Young (onboard): What - what - what - what G&N? Number 6, is that the one that ...

240 31 25 Mattingly (onboard): Yeah. That's the one. Why don't you let me in there ?

240 31 35 Mattingly (onboard): Why don't you let me slide in there, Charlie?

240 31 36 Duke (onboard): Oh, excuse me.

240 31 38 Mattingly (onboard): No, you're okay.

240 31 39 Duke (onboard): Reach it?

240 31 40 Mattingly (onboard): Yeah. Hey, John?

240 31 41 Young (onboard): Yeah?

240 31 42 Mattingly (onboard): They slide in there.

240 31 43 Young (onboard): In here?

240 31 44 Mattingly (onboard): Yeah.

240 31 45 Young (onboard): Okay. Okay, the program alarm resets. This is a nuisance.

240 31 51 Mattingly (onboard): Well, let's - We've got nothing else to do.

240 31 54 Young (onboard): The answer is transient ISS condition.

240 31 56 Mattingly (onboard): Okay.

240 31 57 Young (onboard): Program alarm reset.

240 31 58 Mattingly (onboard): Okay.

240 32 00 Young (onboard): Spacecraft Control, SCS. And - Okay, then it says alarm code. No, the (garble) came off. It just came on again. Alarm code, ICDU to A/D check.

240 32 21 Mattingly (onboard): Did we get both the ISS and the program alarm?

240 32 24 Young (onboard): Yeah.

240 32 25 Duke (onboard): I have P on the ...

240 32 26 Mattingly (onboard): Every - every time?

240 32 27 Young (onboard): Every time to my - Yeah.

240 32 28 Mattingly (onboard): Okay, I did - I haven't seen the ISS light.

240 32 32 Duke (onboard): Well, I - it is on down there.

240 32 34 Mattingly (onboard): That's the PGNS light down there ...

240 32 35 Duke (onboard): No, there's an I ...

240 32 36 Mattingly (onboard): Oh, what's it look like?

240 32 37 Young (onboard): ...right there (garble) ...

240 32 38 Mattingly (onboard): I only saw the ...

240 32 39 Young (onboard): ...my ISS light wouldn't come on, and so ...

240 32 40 Duke (onboard): (Garble).

240 32 42 Mattingly (onboard): Every time?

240 32 43 Duke (onboard): Every time.

240 32 44 Mattingly (onboard): Okay.

240 32 45 Young (onboard): I've been watching it, because it goes out ...

240 32 46 Mattingly (onboard): Does everybody ...

240 32 47 Young (onboard): ...which is why you ...

240 32 48 Mattingly (onboard): Okay, but it goes out.

240 32 49 Young (onboard): I don't give a darn; I seen it.

240 32 50 Mattingly (onboard): All right, John. I'm not saying it didn't come on, I'm saying it goes out as soon as the condition goes away.

240 32 53 Young (onboard): Okay. Well, it's been going out just like that, too.

240 32 55 Mattingly (onboard): Okay. So it means that - right there, you know that it's a - it's a hardware-caused thing and not a software. And let her do ...

240 33 05 Young (onboard): Okay, (garble) again?

240 33 08 Mattingly (onboard): That's strange. Let's - let's do this thing, even if it only takes us to Block 5.

240 33 17 Young (onboard): (Garble) get an answer.

240 33 27 Mattingly: Okay, Hank, when we go into number 6 procedure, we come down, and the logical answer out of Block 2 is that the - you can reset the program lights and the ISS light goes off all on its own. It's only on for a very short period of time. And that says that it's a transient condition and stops. I -- guess we could take a look at going down through the "No" path and try Block 6, but I'd like to have some concurrence on that before we do it.

240 34 02 Hartsfield: We concur - like for you to go to block 6.

240 34 10 Mattingly: You had some bad comm there; I understand you want us to go to Block 6.

240 34 12 Hartsfield: That is affirmative.

240 34 16 Mattingly: Okay.

240 34 16 Young (onboard): Okay, let's do - let's do - why don't you do a Verb 16 Noun 23?

240 34 23 Duke (onboard): Y'all don't need the old LMP for that.

240 34 33 Mattingly: Okay. Before we started on that, we've decided to take a look at 16 20 and it seems to be counting in all three axes. And they agree with what's on the FDAI. We're gonna start into Block 40 now. And I'm going on the Vox so I can talk and read at the same time.

240 34 58 Hartsfield: Roger, Ken. Before you do this, would you check yaw real carefully. We're showing about a degree difference between the ISS att and the ICDUs.

240 35 09 Mattingly: Say again, Hank. You - you were blocked out right in the middle.

240 35 11 Hartsfield: Roger. Could you check the yaw axis real closely; we're showing about a degree difference down here. The other two axes look pretty good.

240 35 21 Mattingly: I - I repeat, the FDAI and the Noun 20s look like they're in as close agreement as I can read. You can't tell a degree on the FDAI down here anyway. (last sentence is Young in the CM transcript]

240 35 32 Young (onboard): I mean, there's that much dispersion in the instrumentation. You know that. Idiots.

240 35 32 Hartsfield: Roger.

240 35 33 Mattingly: There's that much dispersion in the instrumentation. You know that. Okay; can we proceed?

240 35 44 Mattingly (onboard): Okay, can we proceed?

240 35 45 Hartsfield: Proceed.

240 35 50 Mattingly: Okay, we did. And it's counting again, and it's gone back to the same numbers - well, it just blanked again. Let's see here; maybe I was premature.

240 36 07 Young (onboard): What happened there?

240 36 15 Mattingly: That's where it zeroed. Yeah, it's still showing about the same numbers, Hank. The biggest change was in the - no they're all - they're all ball park, within readability, from one reading to the other.

240 36 36 Hartsfield: Roger.

240 36 38 Mattingly: Okay. So out of that, I come up with a "yes" answer, and I'm going - looking at block 12.

240 37 00 Young (onboard): Want to load that?

240 37 23 Mattingly: I guess in order to do this block 12, I have to be in CMC Control, is that not correct?

240 37 32 Hartsfield: Stand by. SCS should be okay, Ken.

240 37 45 Mattingly: Okay. I had no displacement; I did a Verb 43 Enter, and I loaded R-1, 2, and 3 - and I got no needle displacement. Is another Enter required or something?

240 38 06 Hartsfield: Stand by.

240 38 24 Hartsfield: Ken, we'd like for you to repeat the procedure, starting with the Verb 43, and do it very slowly so we can watch it down here.

240 38 33 Mattingly: Okay; there's Verb 43 - Enter, plus 00250 Enter, plus 00333 Enter, plus 00333 Enter, and the needles pulsed out and right back to zero.

240 39 12 Hartsfield: Roger. Copy. The needles did jiggle, but they went back to zero.

240 39 23 Mattingly: That's correct.

240 40 02 Young (onboard): (Garble) that.

240 40 05 Hartsfield: 16, Houston. Stand by a little bit, and we'll digest this a while.

240 40 18 Mattingly (onboard): What did he say?

240 40 20 Duke (onboard): Said stand by a little bit and they'll digest this.

240 40 22 Mattingly (onboard): Oh. Okay.

240 40 26 Young (onboard): Let me ...

240 40 27 Mattingly (onboard): Well, the very first thing to do is to just find out if I have a good alignment. It could well be the detee - the detection circuit.

240 40 39 Duke (onboard): What - what angle are we, Ken?

240 40 42 Mattingly (onboard): 180 roll, 40 degrees yaw, and 130 degrees in pitch.

240 40 50 Duke (onboard): You know, lots of times when those things happen, it depends on - you can just be in a certain attitude and it'll happen ...

240 40 55 Mattingly (onboard): Yeah, yeah, yeah. Sorry - sorry you got to isolate that to a bit when it's ...

240 41 02 Duke (onboard): Yeah.

240 41 03 Mattingly (onboard): ...giving you the problems, so you don't have - which one - which attitudes to avoid.

240 41 31 Young (onboard): It's just like a sim (laughter); 24 hours out instead of 2 (garble) ...

240 41 38 Mattingly (onboard): Yeah, (garble) ...

240 41 40 Duke (onboard): Yeah, Trans-Lunar coast sim, Trans-Earth coast (laughter).

240 41 48 Mattingly (onboard): Well, I'd sure rather have these problems here than in lunar orbit.

240 4l 53 Duke (onboard): Me, too.

240 41 54 Young (onboard): You'd better believe it. Yeah, did we - would - would we still be in lunar orbit?

240 41 59 Duke (onboard): No, we'd be on the way home ...

240 42 01 Mattingly (onboard): No, we'd have been on the way home.

240 42 02 Duke (onboard): ...but 48 hours away instead of -

Public Affairs Officer: This is Apollo Control, Houston; at 265 hours, 29 minutes [240:42] Ground Elapsed Time. What we've been listening, to Ken Mattingly troubleshooting with the ground with the Guidance and Navigation. [The] Program Alarm came on onboard and this was the alarm code 03777 causing the - a warning to the Inertial Sub-System. He has been going through some malfunction procedures now it's - it's being assessed on the ground and we will stand by and continue to monitor as conversations develop. We presently show Apollo 16 at a distance of 116,365 nautical miles away from the Earth; velocity now reads 5,280 feet per second.

240 42 03 Mattingly (onboard): I sure hope that that doesn't prove - You know, that's like McDivitt looking at that - what was it that happened there, and you could see he really made the right decision when he decided to delay the launch even though the information that made it the right decision occurred after he made his decision. (Laughter)

240 42 19 Young (onboard): Yeah, I get a chuckle out of that.

240 42 24 Mattingly (onboard): Fortunately, he's - he's the kind of a guy that's (garble) used to kidding, though. Other people, I think, might believe that kind of reasoning.

240 42 41 Mattingly (onboard): I wonder what the good boss is going to go do? He must have a - I would think running - running ASPO would be enough of a - of a challenge to be worth staying around for. He must have an awfully good job offer.

240 43 01 Young (onboard): Any good job offer would be better than that.

240 43 04 Mattingly (onboard): What? Running the program? Why do you say that?

240 43 08 Young (onboard): His hair is gonna turn gray (Garble).

240 43 14 Mattingly (onboard): That's what makes it a challenge. (Laughter)

240 43 18 Young (onboard): His ulcer is what makes it ...

240 43 20 Mattingly (onboard): That's going to be true in any job you go to. There's probably more talented people working in MSC, and working with NASA, than in any other organization, per capita, unless you get some little group like Bellcomm or something where - and they got their share of them. Strange.

240 43 56 Duke (onboard): (Heavy breathing) (garble) over there.

240 44 10 Mattingly (onboard): Hey, what have you got that thing set on?

240 44 12 Duke (onboard): (Garble) I'm talking ...

240 44 11 Hartsfield: Apollo 16, Houston. The computer looks good to us, and we're checking now to make sure that there's nothing left out in mal procedures.

240 44 20 Mattingly: Okay. Would you like for me to try them in the - in CMC Control, and I'll go to Accel Command so we won't get any attitudes?

240 44 35 Hartsfield: Okay, Ken; give it a go.

240 44 45 Young (onboard): I'll read it up to you, Ken. Verb 43E, load R-1, plus 2 - plus 00250; in R-2, plus 00333 Enter. Whoa! Look at the eight ball.

240 45 09 Young (onboard): As soon as you (laughter) Enter, the needles - they -

240 45 17 Mattingly: Same thing, Hank, as soon as I hit Enter, they pulse out, and it looks like they go to where they belong, and then as soon as it comes back, it just goes out and comes right back.

240 45 28 Hartsfield: Roger. Copy.

240 45 25 Duke (onboard): Is that normal?

240 45 28 Mattingly (onboard): No.

240 45 29 Young (onboard): You ever run it before?

240 45 30 Mattingly (onboard): Yes, sir.

240 45 31 Young (onboard): Okay.

240 45 33 Mattingly (onboard): No, they should go out and stay until you zero them.

240 45 36 Duke (onboard): That's what I would think.

240 45 40 Mattingly (onboard): Yeah, I've run this procedure before. It's -

240 25 h6 Duke (onboard): What is that an indication of, when it goes out?

240 25 48 Mattingly (onboard): Our digital-to-analog section has failed, and we can check that by seeing - Let's see - What - what uses the D-to-A's? The gimbals? The gimbal drive unit uses D-to-A's.

240 46 05 Young (onboard): No, don't turn the (garble) gimbals on, Ken.

240 46 09 Mattingly (onboard): Well, John. The - the reason it's important to you is that this is the way you also coarse align the platform.

240 46 14 Young (onboard): I don't want to coarse align the platform . ..

240 46 18 Duke (onboard): Got to get - got to get entry REFSMMAT.

240 46 20 Young (onboard): Oh, I know.

240 46 22 Mattingly (onboard): Okay. But that's...

240 46 24 Young (onboard): (Garble).

240 46 25 Mattingly (onboard): ...that's something you got to start very, very early on.

240 46 28 Young (onboard): I know that.

240 46 29 Duke (onboard): Why don't we do that?

240 46 30 Mattingly (onboard): Yeah, but only if you plan to do it.

240 46 34 Young (onboard): Yeah, that's what I say ...

240 46 35 Mattingly (onboard): Yeah, I mean, that can also ...

240 46 36 Young (onboard): ...in order to finish this loop, we got - we got to fine align the platform.

240 46 38 Mattingly (onboard): Yeah. Well, what I would like to do is to find out if we've lost that loop. Like right now, even if - even if the gimbals (garble), I'm not sure I would be willing to try to get the coarse align.

240 46 46 Young (onboard): Yeah, but we've got 24 hours to find that out anyway.

240 46 50 Mattingly (onboard): Hey, John, the only other thing besides the coarse align loop that I can think of that - that uses the D-to-A section -

240 46 54 Young (onboard): Yeah. That's what it says over there. Is that what you want ?

240 47 02 Mattingly (onboard): No, I don't. It didn't even mention TVC here, hut I'm sure ...

240 47 10 Young (onboard): (Garble) D to A.

240 47 11 Mattingly (onboard): ...that's how it works. Coarse align there. Can't do that. Can't do that, because it will affect the loads. Oh, wait. Yeah, we can try something like that.

240 47 31 Young (onboard): Are you sure we want to stay in this (garble), Ken?

240 47 33 Mattingly (onboard): Beg your pardon?

240 47 35 Young (onboard): Okay.

240 47 36 Mattingly (onboard): Sure I want to stay in what?

240 47 37 Young (onboard): In CMC. Okay, it wasn't flying. It didn't before.

240 47 42 Duke (onboard): Yeah.

240 47 44 Mattingly (onboard): It's a transient condition now anyhow. Maybe it'll get un-transient later on.

240 47 51 Mattingly: Hank, looks like one other thing that would check the D-to-A's would be - how about if I load a - just a Noun 22 of all zeros, and then call up the Verb 62?

240 48 05 Young (onboard): That would give you an attitude 202?

240 48 07 Mattingly (onboard): Yeah.

240 48 09 Young (onboard): That (garble) what he said.

240 48 12 Hartsfield: Ken, we'd like to have you just stand by, just a minute, here, and - while we smoke this over.

240 48 20 Mattingly: Okay.

Public Affairs Officer: This is Apollo Control, Houston; at 265 hours, 35 minutes [240:48] Ground Elapsed Time. Ken Mattingly aboard Apollo 16 continuing to troubleshoot with Mission Control center. His Guidance and Navigation system following a G&N Program Alarm - this alarm goes to 03777, [meaning] the Coupling Data Unit failed, caus[ing] the Inertial Sub-system warning. At present, Mattingly is - is going through a malfunction procedure which involves punching up a variety of Verbs and Nouns into his onboard computer. We have every reason to believe the onboard computer is working properly. It is a phenomena that has developed and [in] the Control Center, we're proceeding with deliberate speed to try to develop a better understanding of the cause for the Program Alarm. We're at 265 hours, 36 minutes [240:49] and this is Apollo Control, Houston.

240 48 25 Duke (onboard): You say it looks like D-to-A is working there, Ken? Or is it gone completely?

240 48 30 Mattingly (onboard): I don't know.

240 48 32 Young (onboard): Nobody knows.

240 48 33 Mattingly (onboard): I can't tell.

240 48 34 Young (onboard): Charlie, (garble) ...

240 48 36 Mattingly (onboard): I can't think of how a D-to-A could have caused that red alarm the way it came up.

240 48 46 Duke (onboard): Yeah.

240 48 47 Young (onboard): If it's in zero gravity, some kind of mechanical bit in there - something could be bouncing up against it, hit it, and then go back ...

240 48 54 Duke (onboard): If it doesn't get it again.

240 48 55 Mattingly (onboard): I'm more inclined to believe that we had a transient warning in the - in the warning circuit.

240 49 03 Young (onboard): Three of them?

240 49 05 Mattingly (onboard): Yeah.

240 49 06 Duke (onboard): I don't believe that.

240 49 07 Mattingly (onboard): What's the difference if three - Whatever causes transients anywhere...

240 49 10 Duke (onboard): Yeah, (garble) ...

240 49 11 Mattingly (onboard): ...why is it most likely in one circuit than another?

240 49 15 Duke (onboard): It's not; I didn't mean that.

240 49 17 Mattingly (onboard): You were just ...

240 49 18 Duke (onboard): I just ...Page

240 49 19 Young (onboard): If you had one and it never reoccurred, I'd agree, but we already had one ...

240 49 22 Mattingly (onboard): No, it - it's a hardware thing that causes ...

240 49 24 Young (onboard): Is this what - is this what you had before?

240 49 26 Mattingly (onboard): No. No.

240 49 28 Young (onboard): You're probably thinking we got something different than what you had then.

240 49 30 Mattingly (onboard): Well, I'd be bored if I didn't.

240 49 33 Young (onboard): I'm bored already, and I'm (garble) ...

240 49 34 Duke (onboard): Anybody got a Pentel or something?

240 49 35 Young (onboard): ...(garble) be back behind...

240 49 38 Mattingly (onboard): (Laughter) (garble) Why, you want to use it to write on, or ...

240 49 40 Duke (onboard): Yeah, I want to write on that I defecated at 200 and whatever it is.

240 49 46 Mattingly (onboard): Hey, Mabel, when you transcribe the tape, will you record that, please?

240 49 52 Duke (onboard): Yeah, I don't have a pencil, so will you tell the doc ...

240 49 55 Young (onboard): Here. (Laughter) That's a heck of a note.

240 49 56 Duke (onboard): ...what belongs to me. (Laughter)

240 49 58 Mattingly (onboard): Charlie?

240 49 59 Duke (onboard): Yeah? Slide her this way.

240 50 00 Mattingly (onboard): There you go.

240 50 01 Duke (onboard): Oh, I got it. Thanks. (Laughter)

240 50 09 Mattingly (onboard): I can't believe we ...

240 50 10 Duke (onboard): You keep losing it.

240 50 11 Mattingly (onboard): ...the dingaling things we're doing on this mission. Oh.

240 50 25 Mattingly (onboard): Was Henry on the night when I got - got all my transients? I'm gonna have that guy fired.

240 50 31 Young (onboard): Heart rate, about 80.

240 50 34 Duke (onboard): Here you go, Ken.

240 50 35 Mattingly (onboard): Yeah, but that was - that had nothing to do with the Exer-Genie.

240 50 39 Young (onboard): (Laughter) The Exer-Genie was your pacifier.

240 50 44 Duke (onboard): Well, I believe you, Ken. If you say that you can make - you can make an entry without the G - G&N. The - the CMC looks good, though, huh?

240 50 52 Mattingly (onboard): Yeah, it looks good.

240 50 54 Duke (onboard): Good.

240 50 56 Mattingly (onboard): But I'll tell you, at 6gs, when that thing comes up with an ISS warning light, even if you're planning for it, it's going to cause your pittypat to titter or whatever it does. We're gonna see - try Gemini-ing this time.

240 51 22 Mattingly (onboard): Hank was on, with my gimbal that didn't work. Hank's on today. I don't think it was Hank that had the first night, though. That guy's gonna get fired. (Laughter)

240 51 40 Young (onboard): Got up to 90.

240 51 43 Mattingly (onboard): I was in here exercising one day and the doc says, "All right, that's real good. You got your heart rate to 90." And I had just finished checking it, 72. (Laughter) Yeah, I wrote in the - I had just finished writing in the Flight Plan. I - I worked really hard, I thought, and I got it up to 72. And the doc says, "Hey, that's real good. You've - got a heart rate of 90." You ding dongs. That shows how crummy your gear is, anyhow. If he had 90 that day, he should have broken his cardiopack yesterday.

240 52 20 Young (onboard): What happened yesterday?

240 52 24 Mattingly (onboard): Every time Charlie would say how black it was, I'd look out there and my pitty-pat would be all rpm and no torque.

240 52 31 Duke (onboard): Well, I guarantee you, it sure was black. (Laughter)

240 52 45 Duke (onboard): That other one wasn't so bad, was it, you guys?

240 52 48 Young (onboard): That was one of your better ones, Charlie. (Laughter )

240 52 51 Mattingly (onboard): Why couldn't you do those during dinner instead of the others?

240 52 55 Duke (onboard): Well, I don't have ISS lights to get me excited (laughter). I been working on that all ...

240 53 00 Young (onboard): (Garble) ISS light experience. Sure. We don't want you to ...

240 53 04 Duke (onboard): I been work - I been working on that all morning.

240 53 07 Young (onboard): (Garble) warning light stuff; we can't afford it. (Laughter )

240 53 22 Mattingly (onboard): I ought to tell Hank. Never believe what Charlie did when the ISS warning light came on.

240 53 30 Duke (onboard): Had a 17-second void. Why don't you log that ...

240 53 34 Mattingly (onboard): Okay.

240 53 36 Duke (onboard): ...along with it. Make it 18 seconds.

240 53 39 Mattingly (onboard): Okay. (Laughter) An 18 seconder.

240 53 48 Duke (onboard): Yeah.

240 53 49 Mattingly (onboard): And the GET is something like 265:39 [240:52].

240 54 06 Mattingly (onboard): You is logged.

240 54 07 Duke (onboard): Thanks. I can't believe it. It's worse than any sim.

240 54 17 Mattingly (onboard): We sure have had our share of sim problems.

240 54 20 Young (onboard): (Garble) Good.

240 54 30 Duke (onboard): Are we in the exercise period now?

240 54 31 Mattingly (onboard): Yeah.

240 54 32 Young (onboard): What do you think I'm doing, Charlie? I fell behind when he gets an ISS light.

240 54 35 Duke (onboard): (Laughter)

240 54 54 Duke (onboard): Does the - does the D-to-A thing look like it's working, Ken? Or does it still have to pass that test?

240 55 00 Mattingly (onboard): No. They - they don't want me to play and find out.

240 55 02 Duke (onboard): Oh.

240 55 03 Young (onboard): That's right. You don't ...

240 55 05 Mattingly (onboard): I'm gonna play just like I did on that sim, though. I'm gonna give them some time and if they don't come up with an answer, I'm gonna go find out.

240 55 12 Young (onboard): (Garble), you know.

240 55 15 Mattingly (onboard): They can complain all they want to. That's the day I ain't running a training course for G&C.

240 55 38 Mattingly (onboard): Quit hogging the exercise period, John.

240 55 39 Young (onboard): Well, (Garble).

240 55 40 Duke (onboard): How much have we got?

240 55 43 Mattingly (onboard): We got another - Charlie's got to get his in there and I got to get in mine in there.

240 55 45 Young (onboard): One more pull and I'll give it to you.

240 55 48 Mattingly (onboard): I was on - I was on about - I was working ten minutes on my arms, ten minutes on my legs, and then ten minutes back on my arms again, and I ...

240 55 55 Hartsfield: Apollo 16, Houston.

240 55 58 Mattingly: Go ahead.

240 55 59 Hartsfield: Roger. What we'd like to do, Ken, is call up Verb 48. And on Noun 46, set the first digit, digit A, to 0 to kill the DAP; do a Verb 46 Enter; and then we want to go back to block 12 and start with a Verb 43. The boys in the backroom here think that the procedure won't work if the DAP is running even though we're in SCS.

240 56 16 Mattingly (onboard): Who's got my pencil?

240 56 28 Mattingly: Okay. I have done this in the simulator, and it didn't work there, but we'll try this in just ...Okay. You want to set the - you to kill the DAP as number 1 step.

240 56 43 Hartsfield: That's affirmative.

240 56 50 Mattingly: Okay, then you want to go back and go through Step 12.

240 56 56 Hartsfield: That's affirmative, Ken.

240 56 48 Young (onboard): Over here, where the (garble) is.

240 56 50 Mattingly (onboard): Okay, and then you want to go back and go through step 12.

240 56 58 Mattingly: Okay. That's in work.

240 56 59 Mattingly (onboard): have 11101, 01111, okay. Zero. That's good. Just - Just hit 1s.

240 57 22 Young (onboard): Pro?

240 57 23 Mattingly (onboard): Pro.

240 57 24 Young (onboard): Pro. Pro.

240 57 28 Mattingly: Okay. I have to do a Verb 46 on this now. That was one of the no-no's we had the other night. Is that okay?

240 57 38 Hartsfield: That's okay now. That was just to protect the EMP.

240 57 43 Mattingly: Okay, just during the EMP. Thank you

Public Affairs Officer: This is Apollo Control, Houston; 265 hours, 44 minutes [265:57] Ground Elapsed Time. The DAP is the Digital Auto Pilot which provides the interface between the brains of the system the computer and the thruster.

240 58 15 Mattingly: Okay. And now that's working like a champ.

240 58 13 Duke (onboard): There it goes.

240 58 18 Young: Yeah, it works just like it's supposed to, now.

240 58 19 Hartsfield: Roger. Somebody just got the same results over in the CMS, I understand.

240 58 27 Mattingly: Okay. Very good.

240 58 29 Mattingly (onboard): I've done this thing in the CMS and I had the DAP on. There must be some other special condition where that.

240 58 48 Young (onboard): That says that D-to-A ain't it.

240 58 54 Mattingly (onboard): Yeah. You can see, this - this ain't at all conclusive because this is all ...

240 58 58 Young (onboard): Okay.

240 58 59 Mattingly (onboard): ...based on - this is all based on assumption up here, that you - that you couldn't get the lights off. We really had a transient condition.

240 59 07 Young (onboard): I know we did.

240 59 08 Mattingly (onboard): So anything we find down here is only suggestive ...

240 59 10 Young (onboard): Okay. Okay, it's suggestive, but in the - in the final analysis ...

Public Affairs Officer: The next procedure will turn the Digital Auto Pilot back on.

240 59 12 Hartsfield: Ken, we'd like for you to activate the DAP again on a Verb 48, and 1 in digit A, and then a Verb 46.

240 59 26 Duke (onboard): In the final analysis what, John?

240 59 28 Young (onboard): You can't tell visually whether the FDAI is - is reading and all that - you can't tell - you can't tell this right here by eyeball. You'd have to run - you'd have to run a P52 to tell that.

240 59 41 Mattingly (onboard): That's right. I agree with you.

240 59 44 Mattingly: Hank, we'd like to - I'd like to run a P52 here and see - see what kind of torquing angles we get. That would tell us whether or not we really had any kind of - of a hang-up in the A to D section. As short as it was, we couldn't have gotten very far off in attitude.

241 00 06 Hartsfield: Roger. We don't think it moved.

241 00 10 Mattingly: Say again. We were in PTC at the time, so there was bound to be some rates going at the time.

241 00 XX Mattingly (onboard): The fact that the Verb 40 didn't change anything shows that ...

241 00 22 Hartsfield: 16, Houston. Our SIM bay's gonna get too cold, if we don't change attitudes. We'd like for you to roll to 280 degrees and then do the P52.

Public Affairs Officer: The P52 is a computer program which aligns the platform.

241 00 34 Mattingly: Okay. I'll roll to 280.

241 00 36 Mattingly (onboard): I'll do a ...

241 00 37 Young (onboard): The first thing you got to do is (Garble).

241 00 39 Mattingly (onboard): They're close.

241 00 45 Duke (onboard): You through with your exerciser, John?

241 00 47 Young (onboard): Yeah, here.

241 00 48 Mattingly (onboard): Okay, 280 is over here.

241 00 54 Duke (onboard): I got it.

Public Affairs Officer: This is Apollo Control, Houston. We now show Apollo 16 at 115,423 nautical miles away from the Earth. We're at 265 hours, 48 minutes [241:01] Ground Elapsed Time.

241 01 24 Duke (onboard): Charlie, you're so strong.

241 01 27 Mattingly (onboard): Who's giving the big sighs? You guys are huffing and puffing like it's on ...

241 01 30 Duke (onboard): I just started.

241 01 31 Young (onboard): What are you supposed to do? You're supposed to put it on ...

241 01 33 Mattingly (onboard): What - what did you set it on, though?

241 01 34 Young (onboard): I don't know. Whatever it took.

241 01 36 Mattingly (onboard): (Laughter)

241 01 39 Young (onboard): Well, (garble) ...

241 01 40 Mattingly (onboard): Is it up all the way?

241 01 42 Duke (onboard): Well, I don't have no idea.

241 01 45 Young (onboard): Well, Charlie, if that's the thing that you were going to do ...

241 01 47 Duke (onboard): How do you do it?

241 01 48 Young (onboard): Well, I did it like that, but I've never done it like you're doing it.

241 01 52 Mattingly (onboard): How'd you do it?

241 01 53 Young (onboard): (Garble) both.

241 01 57 Mattingly (onboard): I don't think it matters.

241 02 00 Young (onboard): Not if you don't care anymore.

241 02 06 Duke (onboard): (Heavy breathing)

241 02 28 Young (onboard): Like if it was one of those 0.15-degree things. That's the only way you gonna tell, is do a ...

241 02 33 Mattingly (onboard): 52.

241 02 34 Young (onboard): ...(garble) I - I forget how that thing is. I forget what the bits are in the CDUs, but they're like ...

241 02 39 Mattingly (onboard): Plus 4 point ...

241 02 40 Young (onboard): ...22½ sticks in my mind, or 11¼, or plus 5¾. We sure didn't have 11¼ when we were ...

241 02 48 Mattingly (onboard): Well, almost. The only one you could tell with the naked eye (garble) degree.

241 02 56 Mattingly (onboard): (Heavy breathing) (garble) degrees in here.

241 02 57 Young (onboard): Yeah, (garble) if you can believe what kind of eight ball you got here.

241 03 02 Mattingly (onboard): (Garble) ...

241 03 03 Young (onboard): The spec value on the eight ball is (garble) ...

241 03 04 Mattingly (onboard): Well, shoot, just 1.

241 03 05 Young (onboard): ...210.

241 03 06 Mattingly (onboard): One and one-half?

241 03 07 Young (onboard): Yeah.

241 03 08 Duke (onboard): (Garble) specs.

241 03 09 Mattingly (onboard): We're doing a lot better than specs, aren't we?

241 03 10 Young (onboard): Yeah.

241 03 11 Mattingly (onboard): We think it's - I've been watching it, and it's just isn't off more than a degree.

241 03 18 Young (onboard): Yeah, that's one thing that hacked me about this whole business. Here we are flying a platform that's accurate to a hundredth of a degree, and we don't have a display to where we can tell it. You know?

241 03 31 Mattingly (onboard): You need a vernier.

241 03 32 Young (onboard): You need - you need - you need fine displays if you're gonna fly something like this, and tell us beforehand.

241 03 36 Mattingly (onboard): Yep.

241 03 38 Young (onboard): Same way we shut down the Saturn.

241 03 40 Mattingly (onboard): (Garble).

241 03 41 Young (onboard): (Garble) could make it (garble) display where you could manually shut the mother off (garble). Just put it on the - in there - little line knocked off, and say shut down. They chew your tail off if you say anything.

241 03 56 Mattingly (onboard): Oh, yeah. Put it in there with - The thing was, when they built those things, they didn't have those kind of uses in mind.

241 04 02 Young (onboard): No, they had some stupid use in mind. You can bet on that (garble).

241 04 06 Mattingly (onboard): Hey! (Laughter)

241 04 08 Young (onboard): It's working, but we got to check it out. It comes up very shortly, I understand. Sometime today.

241 04 13 Mattingly (onboard): Yeah. Let's see what -

241 04 16 Duke (onboard): What comes up very shortly? Check what out?

241 04 31 Young: Houston, we just wanted you to know that the heart rates that you're seeing or not seeing are due to the exercise period - not the ISS light.

241 04 36 Hartsfield: Roger. We copy.

241 04 38 Young: Although, that could be a factor.

241 04 40 Hartsfield: The Surgeon, I think, had come to the conclusion you must be exercising.

241 05 02 Young: He just doesn't know what an ISS light will do to a body.

241 05 08 Mattingly (onboard): (Laughter)

Public Affairs Officer: This is Apollo Control, Houston; at 265 hours, 51 minutes [241:04] Ground Elapsed Time. That was John Young suspecting that some of the people on the ground may have forgotten what the Flight Plan said and the crew was in fact their exercise period. We now show Apollo 16 at 115,248 nautical miles away from the Earth; velocity now reads 5,318 feet per second.

241 05 18 Young (onboard): My PRD is floating.

241 05 20 Duke (onboard): That's mine.

241 05 21 Young (onboard): (Garble) want to defecate. Go down there.

241 05 30 Mattingly (onboard): Yeah, if there's one kind of malfunction that I really don't like, it's these transient things. They keep you all keyed up -

241 05 37 Young (onboard): (Garble) come on all day, you know? (garble) never see them again.

241 05 48 Mattingly (onboard): Yeah, I know. That's what worries you most. That's that engine that burps then runs.

241 06 08 Duke (onboard): Whew!

241 06 10 Young (onboard): Sweating, Charlie?

241 06 11 Duke (onboard): Starting to get hot.

241 06 12 Young (onboard): Yeah, I start sweating; that's my problem. Had to quit because I ain't - we ain't got any room to sweat in here.

241 06 20 Hartsfield: John, the Surgeon says your heart rate hit a peak of 114 during the exercise period.

241 06 28 Young: I've timed it myself, I only got up to 100. Better check his gear.

241 06 35 Hartsfield: Roger. (Laughter)

241 06 39 Mattingly (onboard): Your gear is a cardboard - probably a cardboard table with little tick marks in it. I can't believe, on that last LBNP test that they ran on our last physical, I ended up with a 30 - 38 heart rate laying on this table.

241 07 08 Duke (onboard): Thirty-eight? Mine's never been - I think 48 was the lowest I've ever been.

241 07 13 Mattingly (onboard): Bet I ain't been that low on this flight. I always thought it was probably ...

241 07 19 Duke (onboard): I bet you that - I bet you when you were sleeping, it was that low.

241 07 22 Mattingly (onboard): I wonder. Man, I tell you, every time I turn around I - I'm paying attention to - little battery compartment that reads 2.8.

241 07 41 Duke (onboard): It does?

241 07 42 Mattingly (onboard): Yeah. No, I'm sorry. 2.6. Excuse me.

241 07 45 Duke (onboard): It's all my fault.

241 07 52 Young (onboard): I don't think they got that psyched out, really.

241 07 57 Mattingly (onboard): They think that they do. You got to be careful of that one because that's the one that - We return that gear, and their analysis is subject to checking.

241 08 15 Young (onboard): (Laughter) You know, you'd be wrong about the gimbal motors (garble).

241 08 18 Mattingly (onboard): Right. They'll have a very positive report about the gimbal motors. (Laughter)

241 08 27 Young (onboard): Yeah. There's always three answers to every question. One one guy knows, the one the other guy knows, and the one that's right.

241 08 42 Young (onboard): Charlie ...

241 08 43 Mattingly (onboard): Why don't you whip off a 52, there, John?

241 08 46 Young (onboard): You want me to do it?

241 08 47 Mattingly (onboard): Sure.

241 08 49 Young (onboard): If anybody can do it, I can.

241 08 55 Hartsfield: Ken, our Pitch has got off a little bit. We need about a 120 degrees in Pitch also.

241 09 03 Mattingly: Is that for thermal reasons, Hank?

241 09 04 Hartsfield: That's affirmative.

241 09 09 Mattingly (onboard): You weenie. I don't believe that.

241 09 13 Young (onboard): Well, they got - I think I got data. I don't know that their thermal rationale is right.

241 09 22 Mattingly (onboard): Okay, now it'll be a second here before I get to that attitude.

241 09 42 Young (onboard): Hey, you got you some stick time, Ken? (garble) Charlie.

241 09 57 Mattingly (onboard): He'd be lucky if he can see anything through that telescope. I don't know. The Sun's at our back, so maybe he can.

241 10 03 Hartsfield: Ken, you want to keep an eye on your roll?

241 10 09 Mattingly: Well, how about telling me what attitude you precisely would like.

241 10 15 Hartsfield: 280, 120, and 040.

241 10 21 Mattingly: Okay. I can do that.

241 10 32 Young (onboard): Yeah, I see stars. Why don't you close up the - can you close up the (garble), you guys?

241 10 36 Mattingly (onboard): Yeah, I'll close up the hatch for you. I can't believe the difference in 280 and 284 means a hill of beans - in this big marshmallow.

241 11 22 Young (onboard): Well, I could see stars there for a while.

241 11 34 Mattingly (onboard): Okay.

241 11 45 Duke (onboard): Okay. Say when, Ken.

241 11 47 Young (onboard): If you can take you some shots, well - let me use the DSKY here. It's a better reference. I'll probably go ahead and do it and then I'll probably get a better hack on the attitude here.

241 12 01 Young (onboard): We got two stars out there and I don't know what they could be.

241 12 06 Mattingly (onboard): Probably Alpha and Beta Centauri.

241 12 09 Young (onboard): (Garble) probably right. Is that where we're pointed now (garble)?

241 12 12 Mattingly (onboard): Yeah.

241 12 14 Young (onboard): That's what they are (garble).

241 12 19 Mattingly (onboard): You don't have Atria next to it?

241 12 21 Young (onboard): No, I can't see it. Ken, let me do it. Okay?

241 12 25 Mattingly (onboard): No, wait a minute, John. I - we'll use the DSKY.

Public Affairs Officer: This is Apollo Control, Houston; at 265 hours, 59 minutes [241:12] Ground Elapsed Time. Apollo 16 is now proceeding to an attitude to shine sunlight into the SIM bay. The next step will be to go to Program 52 to align the platform and check the Inertial Measuring Unit. We now show Apollo 16 at an altitude of 114,857 nautical miles. Velocity now reads 5,326 feet per second. This is Apollo Control, Houston. Ken Mattingly has moved the Apollo 16 into Program 52. This the platform alignment program. We're at 266 hours, 1 minute [241:14] Ground Elapsed Time.

241 13 26 Young (onboard): Okay, now I got all kind of stars up here. There's 1, 2, 3, 4, 5, 6, 7. I don't know what any of them are.

241 13 42 Young (onboard): (Garble).

241 13 55 Young (onboard): Say when, Ken.

241 13 57 Mattingly (onboard): I'll give you the program (garble), John.

241 14 08 Mattingly (onboard): He really didn't mean to just fly over to 280 roll.

241 14 12 Young (onboard): He really didn't mean to do that?

241 l4 13 Mattingly (onboard): No. He meant go to a specific attitude. He just didn't bother to say what it was.

241 14 18 Duke (onboard): I thought he gave you 120.

241 14 19 Mattingly (onboard): Yeah, after I asked for it. I could have gone there the first time just as easy.

241 14 27 Young (onboard): Oh, yeah.

241 14 29 Mattingly (onboard): (Sneeze) Excuse me. (Sneeze).

241 14 32 Young (onboard): (Garble) and Beta Centauri?

241 14 34 Mattingly (onboard): It is?

241 14 35 Young (onboard): Yeah, (Garble).

241 14 38 Mattingly (onboard): You can get Menkent (garble) All right. Now we're going to throw ourselves to attitude rate Att Rate 2, Limit Cycle, On.

241 14 49 Young (onboard): (Garble) sort of oriented ...

241 14 52 Mattingly (onboard): (Garble) power must be on.

241 14 55 Young (onboard): Are we - are we oriented up north?

241 14 58 Mattingly (onboard): Towards the south.

241 14 59 Young (onboard): Towards the south.

241 15 09 Mattingly (onboard): Okay, the first one is star 21.

241 15 12 Young (onboard): Star 21. Gonna have to go to Zero Optics, Ken.

241 15 16 Mattingly (onboard): Yep.

241 15 18 Young (onboard): Zero to Off (garble).

241 15 22 Mattingly (onboard): You'll have to turn the Optics power on before you're going to get anything.

241 15 24 Young (onboard): Okay.

241 15 25 Mattingly (onboard): Turn the Optics power on first.

241 15 27 Young (onboard): Yeah; power on.

241 15 28 Mattingly (onboard): Okay; now Zero the Optics.

241 15 31 Young (onboard): They're Zeroed.

241 15 34 Mattingly (onboard): You did it after the Optics power was turned on?

241 15 35 Young (onboard): No, before.

241 15 36 Mattingly (onboard): No, you got to do it after. Because that's the only way the computer gets its discrete.

241 15 48 Young (onboard): You go to Off and then back to Zero, right?

241 15 50 Mattingly (onboard): Yeah. After the power's on. You have an SCS; you can go to Manual when the drive is finished. Whenever you feel like it, as a matter of fact.

241 16 05 Young (onboard): If I go to Off, that program light hasn't been on...

241 16 11 Mattingly (onboard): Huh?

241 16 12 Young (onboard): That program light?

241 16 13 Mattingly (onboard): What about it?

241 16 14 Young (onboard): (Garble) was on. Do I go back to Zero (Garble).

241 16 18 Mattingly (onboard): No, no - as long as you've been in there 15 seconds. And we'll just check it here.

241 16 32 Young (onboard): Okay, that's close enough.

241 16 37 Mattingly (onboard): Okay, it's your computer.

241 16 42 Young (onboard): Twenty-one.

241 16 58 Young (onboard): Want me to do - try one?

241 16 59 Mattingly (onboard): Yes, sir.

241 17 00 Young (onboard): Twenty-one -

241 17 01 Young (onboard): Mark, 21 is now marked. Okay, now I know where I'm at. Yeah, we're down to about - Okay, fine.

241 17 09 Mattingly (onboard): (Laughter) I told you we were pointing south.

241 17 13 Young (onboard): I know you told me that, but I didn't see any stars out there.

241 18 00 Young (onboard): There you go. CMC. Spica.

241 18 09 Young (onboard): Phew! Boy, it's really getting bad, Ken.

241 18 16 Mattingly (onboard): It's right in the ...

[End of CM transcript.]

241 19 10 Mattingly: Okay, Houston; there are the angles. It does look like that middle gimbal is - might be a little large, but it's - it was late last night when we had the last alignment, so that may be - that may be nominal.

241 19 20 Hartsfield: Roger. We agree it has been quite a few hours since the last P52.

241 19 44 Hartsfield: Clear the torque, Ken.
