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.

Fred and Jim are in the LM.

Okay, Jack. Thank you.

And, Jack, I got LM power on.

Okay. You still with us, Houston?

Okay, Houston. You read 13?

Reading you loud and clear, Jack. I've got a procedure for —

Okay.

— the guys in the LM.

You got another one?

I have an activation procedure. I'd like you to copy it down.

How long is it, Jack?

That's go all the way down to step 3, Jim.

Activation 1 to step 3. Roger.

Houston, Apollo 13. Never mind.

13, say again, please.

Oh, we were curious about Activation 11 on the VHF.

Omit the VHF.

— … Jack. It's got—Okay.

Jack, this is Houston. We want you to keep the IMU up and keep the lights on so you can see in there, and leave battery off—battery A off and, at the appropriate time, we'll put it on MAIN A. And we're going to keep the IMU up so's we can get a coarse aline in the LM.

All right. Real good. Right now, we're charging battery A. Do you want to discontinue that?

Discontinue the charge on battery A, Jack.

Okay, Jack. I discontinued charge on battery A. You give me the call and I'll turn BUS TIE AC on.

Roger. And we want you to keep the lights up and the IMU on.

Okay.

And, Jack, we'd like you to leave the COMM configuration as is until we get COMM with the LM.

Okay.

And, 13, this is Houston. I've got another procedure for the LM. A short one.

Okay. Ready to copy, Jack.

Okay. On panel 11, we'd like you to close the LGC DSKY circuit breaker. Then we want you to go to Activation 25; do steps 1, 2, and 3. Then go to Activation 30, and that will give us a docked IMU coarse aline. Over.

Roger. Panel 11, close LGC circuit breaker. Activation 25, do steps 1, 2, 3, and then do complete Activation 30. Is that correct?

That's affirmative. On panel 11, LGC DSKY circuit breaker closed.

And in the LM, let's go to panel 11 and close the SUIT FAN circuit breaker and get suit fan 1 cranked up.

Okay. Panel 11, close SUIT FAN circuit breaker, and we'll get the suit fan cranked up.

That's affirm.

And, Jack, in the CSM, go to BYPASS on the radiators and turn your GLYCOL PUMP off.

Okay. Pull the BYPASS; GLYCOL PUMP going off.

Roger.

And, 13, in the CSM, we want to verify that all the fuel cell pumps are off, and we want to have you turn off the O₂ fans in the tank 2.

Okay. Tank 2 fans going off. Okay. That leaves me with tank 1 fans on the tank 1 heaters on.

That's affirm.

Fuel cell 2 pump going off now.

Jack, leave them both on in tank 1.

Okay.

13, Houston. We've got AOS on the LM here.

Okay.

And, 13, this is Houston. In the LM, we'd like to have 12, step 3, which is get the batteries on high taps. Over.

Okay.

How you going there? Activation 12, step 3.

Okay. And, Jack, how do you read from Aquarius?

Aquarius, Houston. Say again, please.
