Jack Lousma (CAPCOM): Two things, Jim. We want you to know that there's some pretty big attitude errors in, so if you go to AUTO, the computer is going to try to crank you around, and the other thing is don't drink water out of the LM.
02 15 50 54
Jim Lovell (CDR): Okay. You might think about this. You know we lost our oxygen pressure in the command module.
02 15 51 56
Jack Lousma (CAPCOM): Aquarius, we're finished with the uplink. The computer is yours, and you can open the UPDATA LINK circuit breaker.
02 15 52 18
Jim Lovell (CDR): Okay. We've opened up the UPDATA LINK, and we've gone OFF of DATA, and I've got 16 20 in the computer.
02 15 52 28
Jack Lousma (CAPCOM): Roger, Jim. I guess we're going to just kind of perk away here now.
02 15 52 37
Jack Swigert (CMP): Okay, Jack. One more question about Odyssey here.
02 15 52 45
Jack Lousma (CAPCOM): Go ahead, Jack.
02 15 52 50
Jack Swigert (CMP): Okay. How about the service module O₂ supply valve? Do you want that off?
02 15 53 01
Jack Lousma (CAPCOM): Affirmative. Service module O₂ supply off, Jack.
02 15 53 06
Jack Swigert (CMP): Okay. On the way.
02 15 53 17
Jack Lousma (CAPCOM): And, Jim, we see a PROGRAM ALARM in there. We think it's just got to do with pulling the UPDATA LINK circuit breaker—UPLINK too fast.
02 15 53 30
Jim Lovell (CDR): Roger. I don't see it. Should I reset?
02 15 53 40
Jack Lousma (CAPCOM): Go ahead and reset, Jim.
02 15 56 11
Jim Lovell (CDR): Houston, Aquarius.
02 15 56 16
Jack Lousma (CAPCOM): Go ahead, Aquarius.

Jim Lovell (CDR): One thought that might occur here is that if we have low descent water pressure, we might consider taking the PLSS water and fill it in reverse. If that works, you might look at a procedure for that.
02 15 56 34
Jack Lousma (CAPCOM): That's a good thought. Let us bounce that around a little.
02 15 57 12
Jack Lousma (CAPCOM): Okay, Jim. That's a good thought, and we've looked at that, and it looks like that's feasible. So if and when we need to do that, we will.
02 15 58 11
Jim Lovell (CDR): And, something else, Jack. When it's time for me to make my 90-degree yaw, what I planned on doing was going to NOUN 76 hold and just pulse and yaw several times until the yaw start and hope that pitch and roll stay within the limit.
02 15 58 37
Jack Lousma (CAPCOM): Roger. It sounds like a good plan and you can use your TTCA in MIN IMPULSE to take care of pitch and roll.
02 15 58 47
Jim Lovell (CDR): Okay.
02 16 00 21
Jack Lousma (CAPCOM): Aquarius, Houston. We see ASCENT O₂ tank number 2 building up again, so we'd like to use something out of it, so turn on ascent O₂ tank number 2 and turn off descent O₂.
02 16 00 39
Jim Lovell (CDR): Roger. Opening up ascent O₂ tank number 2, and turning off descent.
02 16 03 01
Jack Lousma (CAPCOM): And, Aquarius, Houston. We're starting to think about CO₂ buildup up in the command module there so we've got a recommendation, and what we're recommending is that you take the commander's hoses in the LM and put a cap over the red return hose and then figure out a way to fasten those hoses so they blow up into the CSM by extending them up through the tunnel as far as possible. And we'll get some flow out the blue side, circulate up and around the command module and to keep the CO₂ level down.
02 16 03 43
Jim Lovell (CDR): Roger. We're thinking of that too, and one problem is that the COMM is connected securely to the hose, so we've got to get the COMM cable off somehow to get that—So we'll still have COMM down here in the LM and you have the hose up there.

02 16 05 10
Jim Lovell (CDR): Houston, we're trying to extend that commander's hose by use of the vacuum hose.
02 16 05 22
Jack Lousma (CAPCOM): Sounds like a good plan if you can work that out, Jim.
02 16 06 58
Jack Lousma (CAPCOM): Aquarius, if you can shake Jack loose there, I've got a—some procedures for him to write down.
02 16 07 09
Jim Lovell (CDR): Okay. Stand by.
02 16 07 33
Jack Swigert (CMP): Okay, Jack. Is this a long one?
02 16 07 37
Jack Lousma (CAPCOM): Oh, it's about 12—15 lines. It's a matter of verifying some valves and so forth.
02 16 07 50
Jack Swigert (CMP): Okay. Go ahead.
02 16 07 53
Jack Lousma (CAPCOM): Okay. We want you to go in when you can and verify the following valves and leave them as we outline here. REPRESS PACKAGE valve, off; EMERGENCY CABIN PRESSURE, off; DIRECT O₂, off; DEMAND REG, off; both WATER ACCUMULATORS, off; MAIN REG A and B, open; WATER GLYCOL—correction—WATER and then GLYCOL TANK INLET and OUTLET, both. Now if you want to get some water, we recommend that you momentarily turn the SURGE TANK on to pressurize the system and then turn it off and take out water as required. Over.
02 16 09 33
Jack Lousma (CAPCOM): That's it, Jack. And another note on taking water; if you don't drain enough water so that —
02 16 09 49
Jack Lousma (CAPCOM): Say again, Aquarius.
02 16 09 53
Jim Lovell (CDR): That wasn't us, Jack.
02 16 09 58
Jack Lousma (CAPCOM): Okay. One more note on the water, Jack. If you don't bleed the pressure off when you—don't take enough water to bleed the pressure off completely, the pressure that's left on there is going to drain away in a period of 1 to 3 hours. So it's a small amount of oxygen, but we might as well save it. So if you want to eliminate that problem you could completely drain the pressure off by putting the water in a water bag and saving it that way.
02 16 10 36
Jack Swigert (CMP): Okay. That's a good idea.
02 16 10 38
Jack Lousma (CAPCOM): So that's the end of my —
02 16 10 39
Jack Swigert (CMP): What I'll do—let me repeat—Okay. Let me repeat it all back to you. REPRESS PACKAGE VALVE, off; EMERGENCY CABIN PRESSURE, off; DIRECT O₂, off; both the DEMAND REGs, off; both H₂O ACCUMULATORS, WATER GLYCOL ACCUMULATORS, off; MAIN REG A and B, open; WATER and GLYCOL TANK INLET and OUTLET, open; for water, momentarily pressurize the SURGE TANK, take out water as required. You're recommending drain out all the water until I can't get any more water out of it in order to conserve the oxygen.
02 16 11 34
Jack Lousma (CAPCOM): Okay. We just want you to turn off the water accumulators and not the glycol accumulator. Over.
02 16 11 49
Jack Swigert (CMP): Okay. These are the water accumulators on 382, right?
02 16 11 57
Jack Lousma (CAPCOM): That's affirm. The accumulators on 382.
02 16 37 40
Jim Lovell (CDR): Houston, Aquarius.
02 16 37 43
Jack Lousma (CAPCOM): Aquarius, Houston. Go.
02 16 37 48
Jim Lovell (CDR): Roger, Jack. We're asking whether P51 and a P52 are required in the back side of the Moon.
02 16 37 56
Jack Lousma (CAPCOM): I think so, Jim, but stand by while I verify it.
02 16 38 23
Joe Kerwin (CAPCOM): Aquarius, Houston.
02 16 38 28
Jim Lovell (CDR): Go ahead.
02 16 38 30
Joe Kerwin (CAPCOM): We think we know where the platform is, Jim. The tracking looks real good from the last burn. We feel just a P52 will be required.
