You know, somehow, everytime I do a set of P23s, you guys uplink me a state vector. I don't think I do too well.
- Vance Brand (CAPCOM)
-
No. You know—you know how the FIDOs are. They like to load in their own data, no matter what.
- Vance Brand (CAPCOM)
-
And as a matter of interest, understand that the downrange comparison between the MCC and the computer is within 35000 feet, and that's on the last sighting, which people think is pretty good.
- Jack Swigert (CMP)
-
Okay. Maybe that gives us a little more confidence that if we had to do P23s on the way home, we'd make it.
- Vance Brand (CAPCOM)
-
Just info on your PTC, Jim. It's looking very good. Just—excursions in pitch and yaw are very low.
- Vance Brand (CAPCOM)
-
Well, a minute ago, he said that to tell you that he was pacified now after your past comments on his trajectory and so forth, and he hadn't seen any waste water dumps or anything and he's pretty happy.
- Jack Swigert (CMP)
-
Okay. BAT C 37, PYRO BAT A 37, PYRO BAT B 37, RCS A 97 percent, B 97 percent, C 96 percent, D 97 percent.
- Vance Brand (CAPCOM)

Jim, just an item for you and Fred to be thinking about in case you haven't been briefed on this, something that's now being talked about a little bit. These conservative people would like to have you read the SHe tank pressure when you go into the LM for the LM familiarization at 58 hours. If there's no midcourse-3, and it looks like there's a good chance that there will not be, why, they might want to move the LM familiarization up from 58 to 55 hours. Over.

Okay. If we don't have a midcourse-3, then we'll probably move LM FAM up to 55 hours, in which case we'll go in there and read SHe tank pressure.
- Vance Brand (CAPCOM)
-
Roger. Along with the other FAM stuff, and it's not certain that we want to do this, it's just being talked about, so this is just the information for you.
- Fred Haise (LMP)
-
Oh, we just finished eating and cleaning up a bit afterwards. Jim's going around collecting debris off of all the inlet hoses. And, I guess you might say we're kind of thinking about getting ready to go to sleep.
- Vance Brand (CAPCOM)
-
Sounds like you guys are really living it up up there. All that music, food. I didn't say drink.
- Fred Haise (LMP)
-
Yes, it is pretty nice. Not bad at all. You're right; you didn't say it. This PTC we're in is a pretty—pretty nice merry-go-round, Vance. Every 10 minutes alternately I get to look at the Earth and the Moon.
- Fred Haise (LMP)
-
No, it's a lot—a lot better. I remember from 8 when they didn't hardly ever get to look at either one.
- Fred Haise (LMP)
-
It's pretty cloudy down there tonight. About the only land I can see again is a portion of Australia and Korea and looks like a part of China. Just about clouds covering everything else.
- Vance Brand (CAPCOM)
-
Can you still see that clearly with the naked eye, or do you have to look through a glass?
- Fred Haise (LMP)
-
I can see Australia with the naked eye and the China landmass, but I—It took the monocular to pull out the Korean Peninsula.
- Vance Brand (CAPCOM)
-
I understand that they're estimating your pericynthion—lunar pericynthion is now 62 miles.
- Jack Swigert (CMP)
-
Okay. We're into the presleep checklist now. As far as the crew status report, as far as medication goes, we've had no medication. And we're all feeling really good. I've given you the onboard readouts. Jim is chlorinating the potable water now. I'm ready for an E-memory dump whenever you're ready.
- Vance Brand (CAPCOM)
-
Stand by 1 on the E-memory dump, Jack. I think we'll be ready in about a minute.
- Vance Brand (CAPCOM)
-
And EECOM says that as soon as you stir your cryos, request you go back to AUTO on that one tank.
- Jack Lousma (CAPCOM)
-
Roger. We saw the downvoice subperiod come on. We thought maybe you were trying to call. Sorry. I hope we haven't disturbed you and from where I sit, it looks like you're running a rest home up there. Good night.
- Jim Lovell (CDR)
-
We're all going to bed now just after we play the last rendition of “With Our Eyes on the Stars.”
- Jack Lousma (CAPCOM)
-
Okay, Jim. If we need you, we'll send a crew alert, and we'd like to know who's got the duty tonight on the BIOMED. Is that you?
- Jack Lousma (CAPCOM)
-
Okay. We copy, and you're spoiling my good record of two watches without saying anything.
- Jim Lovell (CDR)
-
Ah so. I just thought I'd be waking up. And we are awake and getting the spacecraft shipshape. …
- CapCom
-
Roger. Spacecraft is in real good shape as far as we're concerned, Jim. We're bored to tears down here. We do have a few little items for you, like a P37 update and a couple of flight plan updates. But there's no rush about them. Over.
- Jim Lovell (CDR)
-
Okay. Gig us again in a few minutes. We're breaking out some food, and we'll copy them then.
- Jim Lovell (CDR)
-
Righto. If he's listening, LMP had a solid 9 hours of sleep; I couldn't wake him up this morning. The CMP had 6 hours, and the commander about 5 intermittent.
- Jim Lovell (CDR)
-
It might be interesting that just after we went to sleep last night we had a MASTER ALARM and it really scared us. And we were all over the cockpit like a wet noodle.
- CapCom
-
(Laughter) Sorry it wasn't something more significant. I've also got a procedure for you on that H2 tank; simple thing after you get done stirring up the cryos.
- Joe Kerwin (CAPCOM)
-
Okay. Got it right here, Jim, and it follows. This is the P37 pad for lift-off plus 60. The reason for the update is for weather avoidance in the MPL at 119 hours. It's the same one we passed you yesterday, and it's the same weather, but we still don't expect a problem at the end of the mission. GETI is 060:00, DELTA-VT 6079, longitude minus 153, GET 400K 118:04. Over.
- Joe Kerwin (CAPCOM)
-
Roger. That's correct. I've got a consumables update for you, Jim, if you're ready for that.
- Joe Kerwin (CAPCOM)
-
Okay. As of 47 hours, RCS total 1096, quad Alfa 270, Bravo 278, Charlie 270, Delta 278, and the H2 — They gave me the H2s in percent, 76 percent; and on the O2 we have 81 percent. However, we show the O2 tank 2 reading off-scale high now. We're quite sure it's a sensor failure. We'd like you to verify it with your onboard reading.
Expand selection down Contract selection up - Jim Lovell (CDR)
-
Joe, we confirm. Our gage reading is—on the number 2 O2 tank is reading off-scale high now, but Jack just tells me that it was okay when we first looked at it this morning.
- Joe Kerwin (CAPCOM)
-
We verify that. At 46:45 we had 82 percent and apparently when he stirred the, the cryos, the sensor broke.
- Joe Kerwin (CAPCOM)
-
So it's no problem. You're above nominal on all your consumables. On the H2 tank problem, we have a procedure that we'd like you to carry out which is simply turning the H2 tank 2 heaters to OFF at this time, and we want to see whether that won't solve the problem of the tank pressure setting off caution and warning. We want to look at it that way for a few hours.
- Joe Kerwin (CAPCOM)
-
Okay. Good deal. That's been the high tank and apparently while waiting for that pressure switch to close, to start the heater cycle, the tank 1 pressure has been dropping even a little bit lower and just setting off caution and warning, so we feel if we turn off the tank 2 heater and let tank 1 activate the heater cycle, we won't get into the caution and warning range.
- Joe Kerwin (CAPCOM)
-
Okay, Jim. At your convenience we'd like P00 and ACCEPT. We're ready for—to uplink your state vector now since we will not do midcourse 3. Over.
- Jim Lovell (CDR)
-
Roger. You're in P00 and ACCEPT, no midcourse 3, and we're all set for a state vector update and I'm giving you the LM/CM DELTA-P here shortly.
- Joe Kerwin (CAPCOM)
-
Okay. Good deal. And I have flight plan updates for you later, at your convenience.
- Joe Kerwin (CAPCOM)
-
Okay, 13. To start off with, got a minor procedural change for Jack on his next P52, if he's ready to listen to that.
- Jim Lovell (CDR)
-
Okay. Jack's still off COMM. We'll hold off on that a little bit and then we'll pick it up when he gets on COMM.
- Joe Kerwin (CAPCOM)
-
Okay; fine. I've got two updates for you, Jim. One is a procedure for looking for Comet Bennett at about 49:45, and I'll wait till Jack gets up before passing you the details on that. The other update is concerned with going into the LM 3 hours early, and I think Vance mentioned to you last night that this was a possibility, that we'd like to look at the SHe tank pressure early. And since we're not going to do midcourse 3, we'd like LM entry at 55 hours. Is that okay with you?
- Joe Kerwin (CAPCOM)
-
Okay. I've got some details on the flight plan for you as follows. Of course, since there's no MCC-3 you'll be deleting all the midcourse 3 stuff including the—the P52, which is called out at about 54-1/2, and we'll be slipping that until later, which I'll—which I'll tell—which I'll tell—which I'll tell you in a minute. Okay. Then you—we want to move the battery charge up 3 hours to about 52:30. And we want to move the—moving the LM tunnel vent valve to LM/CM DELTA-P up 3 hours to 52:45, and at that point you can simply go to the 57-hour point in the flight plan and change your number from 57 hours to 54 hours and start through that. In the remarks section at about 57:50 it says, “O2 fuel cell purge and waste water dump,” here. If not performed earlier, we want you to do that at 54 hours and 50 minutes. The TV pass then, will be at 55 hours to 55:30. You'll go right through the LM Activation checklist stuff. I'm losing you; let's wait a minute.
- Joe Kerwin (CAPCOM)
-
Okay. I've gone through the battery charge, the LM vent valve, the fuel cell purge, and then stop PTC at 55 hours, and your roll attitude there will be 285 degrees, which is per the flight plan. The high gain antenna angles are slightly different, pitch 23 and yaw 267 degrees. The TV pass till 55:30, the standard LM activation except for some special steps we'll give you to take a look at SHe tank pressure, which I don't have yet. Restart PTC at about 56:30 or whenever you're through with the LM activities, and after that, at your convenience, we'd like you to—to do the P52 option 3 that we cancelled at 54-1/2 hours. Over.
- Jim Lovell (CDR)
-
Okay. That last comment was that we'll do the P52 after we start PTC at about 56:30.
- Jim Lovell (CDR)
-
Okay. Let's see if I have some of this, Joe. Around 52:30 we're to do the battery charge on BAT—battery B.
- Jim Lovell (CDR)
-
And then about 52:40 we're going to do the LM tunnel vent valve, and the LM/CM DELTA-P which has been written up at 55:40.
