Spacelog Apollo 13

That's affirmative, Jim.

Activation 11, omit step 1, do the rest. Is that correct?

That's affirmative.

Do Activation 12 and Activation 13, step 1.

That's all correct.

Okay, Jack. Pressure in tank 1 is approaching 100 psi. What's going to be the symptoms of this fuel cell starting to drop off?

Stand by, Jack. We'll get the word on that.

Okay.

And, Jim, when you get to the end of that procedure, we'd also like to have you put the DEMAND REGs to CABIN.

DEMAND REGs to CABIN. Roger.

Jack, was that Activation 1, step 3 only, or all of Activation 1?

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.

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.
