Spacelog Apollo 13

Apollo 13, Houston. We'd like to charge battery A now.

Charge battery A. Roger.

And, Jack, in regard to your question about the P52 and LM platform, it's—There's no need to worry about that now. We wouldn't be using the LM platform for—until about 79 hours, so let's go as is on the platform for now. Over.

Okay. We understand.

And, Jack, we've turned off the waste dump heater. If you're going to consider dumping any more waste water, we probably ought to do it while the duct is warm there.

Roger. Stand by, Jack.

Okay.

Okay, Jack. Let's keep the water; no need for a dump right now.

All right.

13, Houston. We see the PROP ISOL valve on RCS quad Charlie closed, so we'd like to also disable AUTO RCS feature in quad Charlie.

You want to isolate the AUTO RCS features in quad Charlie?

Affirmative.

Okay, Jack. I didn't plan to reset that quad Charlie DROP ISOL valve. Do you want me to do that? Okay. We just tried it and quad Alfa and Charlie barber poles are showing.

Stand by, Jim.

Okay, Jack. That's the sec—secondary propellant barber poles on Alfa and Charlie.

13, Houston. It won't do any good to try to power the propellant valves on A and C, so we want you to disable the AUTO on RCS Charlie. And we have a procedure for getting power from the LM we'd like you to copy down.

Okay.

Stand by, Jack.

That sounds like good news.

Okay, Jack. About how long is it?

It's not a very long procedure, Fred. We figure we've got about 15 minutes' worth of power left in the command module, so we want you to start getting over in the LM and getting some power on that. And, you ready to copy your procedure?

Okay.

Okay. In the CSM.

Stand by.

Go ahead.

Okay. In the CSM on panel 5, circuit breakers LM POWER 1 and 2, OPEN. Then LM POWER switch, reset and release. In the LM, on panel 11 and panel 16, TRANSLUNAR BUS TIE. Both circuit breakers CLOSE. On panel 16, circuit breaker ASCENT ECA CONTROL, CLOSE. On 16, DESCENT ECA CONTROL, CLOSE. On panel 14, put your BAT 5 NORMAL feed ON. BATs 1, 2, 3, and 4 LOW VOLTAGE taps, ON. BAT 5 NORMAL feed, OFF. ASCENT ECA CONTROL, OPEN. You copy?

Stand by 1.

Okay. In the CSM, on panel 5, we want CB LM POWER 1 and 2, OPEN. Then the LM POWER switch to reset, release. In the LM, panels 11 and 16, X LUNAR BUS TIE breakers closed. On panel 16, the ASCENT ECA CONTROL closed; the DESCENT ECA CONTROL closed. On panel 14, BAT 5 NORMAL feed ON, followed by BATS 1, 2, 3, and 4 LOW VOLTAGE taps ON. Then BAT 5 NORMAL feed OFF. Then ASCENT ECA CONTROL breaker OPEN.

That's a good readback, Fred.

And, 13, Houston. As a final effort here, we would like you to turn on the fans in tank 2. Over.

Roger. Understand. Turn on the fans in tank 2.

You want the O₂ fans in tank 2, Jack?

That's affirmative, Jim.

O₂ tanks—fans in tank 2 are on.

Roger.

13, Houston. We'd like you to start making your way over to the LM now.

How long is it, Jack?

It's just four lines. Go to Activation 1, do step 3. Go to Activation 11, omit step 1. Do Activation 12, and then go to Activation 13 and do step 1. Do you copy?

Okay. Is that Activation 1? Do step 3. Is that correct?
