Jim Lovell (CDR)

And, Houston, while you're thinking, see if you can come up with a procedure of perhaps using the command module optics with manual drive to perhaps look for stars.

Jim Lovell (CDR)

And, Jack, Aquarius. While you're thinking—before we had our COMM problems, we were wanting to know what to—whether we should hook up the side hatch urine dump system. So we wouldn't freeze up the normal urine dump system.

Jack Lousma (CAPCOM)

Roger. We gave you a GO on that earlier. Sorry, you must have missed it. Use the side hatch for urine dump.

Jack Lousma (CAPCOM)

And, how are the stars out the window now?

Jim Lovell (CDR)

Well, I'll look again, Jack, but at this attitude, the Sun is reflecting off of—off of quad 4 so bright that it's ruining any night vision and we still got particles floating around us; I'll have to take a long look and see if I can see any star patterns.

Jack Lousma (CAPCOM)

Roger. And Aquarius, we're going to have to hand you over to a different site now, and we think maybe things will work better if this time we turn off the S-band transmitter/receiver, and bring it back up in 5 minutes. You copy?

Jim Lovell (CDR)

Okay. I understand you want us to turn off the S-band transmitter/receiver and bring it up in 5 minutes. Is that correct?

Jim Lovell (CDR)

And you want us to maintain attitude control.

Jack Lousma (CAPCOM)

Affirmative on the attitude control.

Jim Lovell (CDR)

That's auto attitude control. Okay. You maintain auto attitude control.

Fred Haise (LMP)

Okay, Jack, I'm back on the line now. On the S-band, you want me to turn off the transmitter/ receiver and the power amps are off for 5 minutes. Is that—when you give me the word—is that what you want?

Jack Lousma (CAPCOM)

Aquarius, leave the power amplifier the way it is. Turn the transmitter/receiver off for 5 minutes. Now.

Fred Haise (LMP)

Okay. You tell me—you tell me when.

Jack Lousma (CAPCOM)

Okay. Turn it off now. See you in 5 minutes.

Fred Haise (LMP)

Okay. It's gone off. It's gone off for 5 minutes.

Jack Lousma (CAPCOM)

Aquarius, Houston. How do you read?

Fred Haise (LMP)

Okay. You're loud and clear there, Jack.

Jack Lousma (CAPCOM)

Roger. Same here. We're—We're still discussing the next move.

Fred Haise (LMP)

I figured it. Let's just make it a good one.

Jack Lousma (CAPCOM)

We're looking real close at water usage profiles, and right now things are kind of swinging toward leaving the IMU powered up and powering down the LGC, but we'll have more word for you shortly. And we recommend for sleeping that you leave one guy on watch. We recommend you don't make any urine dumps if you can help it, because it'll make the debris problem worse than it is now. And we have some items that you might want to transfer to the LM, some towels, some penlights, fecal bags, UTS. And do you have any more items that we can help you out with at the moment?

Fred Haise (LMP)

Okay. Stand by on your latter list there, Jack. I understand no urine dumps. I guess we'll work through the UCD and all the bags we got; and real quick there, can you give a DAP load that we want in here now to conserve the RCS.

Jack Lousma (CAPCOM)

Okay. For attitude control coordinates, we're recommending manual control VERB 76 and watch your middle gimbal angle. Your DAP load that you have now looks good.

Fred Haise (LMP)

Okay. It's ATT HOLD VERB 76 for the guy on watch. And the DAP load we got right now is okay.

Jack Lousma (CAPCOM)

Aquarius, our decision for the time is to leave the IMU powered up, power down the LGC, and power down other nonessential items. We'll be coming up with a more precise checklist as soon as we can get it. Over.

Fred Haise (LMP)

Okay. The decision is to keep the platform, power down the computer, and we'll be standing by for further word on the powerdown, Jack.

Jack Lousma (CAPCOM)

And, Aquarius, for your information, we now have 136-mile perigee. Confirmed by Doppler.

Fred Haise (LMP)

Okay. 136-mile perigee now. That's very nice.

Fred Haise (LMP)

Oh, wait a minute, Jack. Did you say pericynthion or perigee?

Jim Lovell (CDR)

And, Houston, we pulled out your UPDATA LINK circuit breaker, so if you want to update it for anything, let us know and we'll put it back in.

Jack Lousma (CAPCOM)

Aquarius, AFT OMNI, please.

Fred Haise (LMP)

Houston, do you read Apollo 13?

Jack Lousma (CAPCOM)

This is Houston. Go ahead. Reading you weakly.

Jim Lovell (CDR)

Okay, Jack. We don't want to bug you, but you ought to be thinking—or what your thoughts are concerning what the next burn will be. I got to figure out a watch schedule and the sleep schedule and just how we can meet the next maneuver.

Jack Lousma (CAPCOM)

Roger. We're getting you a flight plan update. We're still computing on your next burn, and we're getting ready to give you a procedure for powerdown.

Jack Lousma (CAPCOM)

Aquarius, one idea on managing the OMNI antennas. It might make it easier on everybody if we disabled the UPLINK SQUELCH and managed the antennas by switching when we hear the noise. Over.

Jack Lousma (CAPCOM)

Okay, Aquarius. Here's what we're going to do. We'd like you to point the LM X-axis either north or south. That's the positive X-axis. It appears to us that it would be closer to orient the LM plus X-axis toward the south. Do that with the LGC powered up using the TTCA. After that, we propose to power down the LGC to save some power. However, this means that we lose the use of the TTCA, and we'll have to control the spacecraft with the hand controller in the DIRECT mode. Request your—your position on these two items.

Jack Lousma (CAPCOM)

Aquarius, Houston. How do you read?

Jim Lovell (CDR)

Okay, Jack. Understand. You want us to point the LM X—plus X-axis to the south using the TTCAs with the LGC powered up. Then, by powering down the LGC, we'll lose a TTCA. I wasn't too successful in controlling the spacecraft in attitude only, but I might be able to keep it out of gimbal lock.

Jack Lousma (CAPCOM)

That's affirmative, Jim. We'd keep your ball powered up and go to DIRECT on the hand controller. And maintain attitude in a DIRECT position.
