Spacelog Apollo 13

That's affirm.

Yes, We've transferred that.

Okay. Good deal. Jack, let me mention something about the hatch integrity check. You're going to vent the tunnel until you get a 3-psi DELTA-P. That should take 9 or 10 minutes, and it's our firm feeling that you don't have to wait another 10 minutes after that for a leak check. If it holds pressure for a minute or so or even gets down there, you know you've got a good hatch. Over.

Okay. Copy that.

Okay, Houston. We've got an O₂ FLOW HIGH.

Okay, Jack, are you -

Well, we might be pressurizing a lot of the system that was not pressurized.

Roger. I expect that's the case. Let us check it.

Okay. Take a good look at CABIN.

Will do.

Odyssey, Houston, just verify your DIRECT O₂ is OFF. Over.

Yes, sir. That is verified.

Okay, and —

… It's dropping now, Joe.

Roger. We think that you were just pressurizing the cabin up to that regulator's particular SPEC.

Odyssey, Houston.

Go ahead.

Okay. We're observing middle gimbal angle getting a little bit high. The LM appears to be deadbanding okay within its attitude, but just wanted you to know that we're keeping an eye on it and if it does get too high, we might want you to punch off early.

Okay.

And verify that the hatch is secured and that you are venting the tunnel. Over.

That's verified. We have a DELTA-P of 2.8.

Real good. Real good.

Okay, Joe. Since we're ahead of the time line, can I proceed on and kind of punch off early, or do you want me to punch off at exactly 1 hour?

Jack, when you are comfortably ready to punch off, you can go ahead and do it.

Odyssey, Houston. We just had a formal GO for LM JETT at your convenience. Over.

Okay. Thanks, Joe.

Okay.

Okay, Odyssey; Houston. We're ready for you to bring the BMAGs ON and WARM UP and all other things being equal, we'd like you to go through the LM JETT at—on the checklist you've got. And that is BMAGs 1 —

Okay. Will do.

— 1. That's BMAG 1 now, as you know.

Yes, BMAG 1 is in WARM UP.

Okay, Houston. Do you have a command module weight for me?

Stand by 1, Jack.

Odyssey, Houston.

Go ahead.

Okay. I'm reminded that the entry DAP is all you've got. It'll initialize itself, and you won't have an—you won't have an RCS DAP, so you don't have to fool with it.

Okay.

Okay, Joe. I'm—Have you got your checklist out there on the SPS powerup?

That's affirm.

Okay. I'm coming down here to a step that says FDAI POWER, off. Is that what you want right now, I guess, huh?

Go ahead.

Okay, Jack. That FDAI POWER, OFF, is to stop momentary gliches as you bring up the BMAG to put it on, and you turn right around and put the FDAI POWER right back on 1.

Okay. And I don't have the BMAG TEMP light out yet. Do you want me to go ahead and put the BMAG ON with the TEMP light still ON?

That's affirm. We can go ahead and you'll have a good stable rate.
