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.
-
Jim Lovell (CDR)
-
Okay. You might think about this. You know we lost our oxygen pressure in the command module.
-
Jack Lousma (CAPCOM)
-
Aquarius, we're finished with the uplink. The computer is yours, and you can open the UPDATA LINK circuit breaker.
-
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.
-
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.
-
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.
-
Jack Lousma (CAPCOM)
-
That's a good thought. Let us bounce that around a little.

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.
-
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.
-
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.
-
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.
-
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.
-
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.
-
Jack Lousma (CAPCOM)
-
Aquarius, if you can shake Jack loose there, I've got a—some procedures for him to write down.
-
Jack Lousma (CAPCOM)
-
Oh, it's about 12—15 lines. It's a matter of verifying some valves and so forth.
-
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.
-
Jack Lousma (CAPCOM)
-
That's it, Jack. And another note on taking water; if you don't drain enough water so that —
-
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.
-
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.
-
Jack Lousma (CAPCOM)
-
Okay. We just want you to turn off the water accumulators and not the glycol accumulator. Over.
-
Jim Lovell (CDR)
-
Roger, Jack. We're asking whether P51 and a P52 are required in the back side of the Moon.
-
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.
-
Joe Kerwin (CAPCOM)
-
Roger, Jack. We're still looking at 137 miles and Doppler's confirming it. We will have a good update after 67 hours.
-
Joe Kerwin (CAPCOM)
-
Okay, Jim. We've come up with a COMM recommendation which we hope will save some power by powering down the power amplifier, if it works. And I'd like to read up the steps to you and have you think about them for a minute, and we recommend trying it before the first yaw maneuver. Over.

Joe Kerwin (CAPCOM)
-
Okay. Step 1, BIOMED off; step 2, go to LOW BIT RATE; step 3, go to DOWNVOICE BACKUP; step 4, POWER AMP to PRIME; step 5, panel 16, POWER AMP CIRCUIT BREAKER open; step 6, RANGE FUNCTION switch, off. Read those back to me, and then I'll have a remark.
-
Jim Lovell (CDR)
-
Okay. BIOMED, off; LOW BIT RATE; DOWNVOICE BACKUP; POWER AMP to PRIME; circuit breakers, panel 16, POWER AMP CIRCUIT BREAKER, open. RANGE FUNCTION switch, off.
-
Joe Kerwin (CAPCOM)
-
Okay. And the note says that you should be able to hear us. If we can't hear you in a couple of minutes, you should close the POWER AMP circuit breaker on panel 16, and we expect to save an amp or more on this. It should work in the present attitude. When we go to the new yaw attitude, we're thinking about powering up the steerable, leaving the POWER AMP off and, if we can get good COMM in that mode, we'll still save some power. So if you concur, why don't you go ahead.
-
Jim Lovell (CDR)
-
Okay. In this mode, you should hear us—or we should hear you, but if you can't hear us, then we ought to close POWER AMP circuit breaker again. Is that right.
-
Joe Kerwin (CAPCOM)
-
That's affirm. We'll just run a little COMM check after you get done and see how we're doing.
-
Jim Lovell (CDR)
-
Okay. Circuit breakers 16, POWER AMP circuit breaker, open; COMM; POWER AMP circuit breaker, open.
-
Joe Kerwin (CAPCOM)
-
Aquarius, this is Houston. We read you with a lot … static. How do you read us? Over.
-
Joe Kerwin (CAPCOM)
-
I didn't copy your last remark, Jim. I heard that you had a lot of noise in the background also.
-
Jim Lovell (CDR)
-
Okay. I'll tell you what we need, Jack. Try to get this squared away again. We—See if you can't report the right procedures here. … the procedures, the whole works, before we get all balled up here.
-
Fred Haise (LMP)
-
Why don't you put that right up there, just like that. Is that all you've got on it? There you go.
