Spacelog Apollo 13

Okay. Copy that. No complaints.

Okay. We're ready to proceed with hatch closeup.

Okay. Did Jim get the film out of Aquarius?

Yes. We—You mean the film we took this morning?

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.

Watch gimbal lock there, Jack.

Yes, we did.

Odyssey, Houston.

Go ahead.

Okay, Jack. We'll have a pad for you in a few minutes. We're getting data now on the tracking, and although we suspect the changes from your preliminary pad will be very small, we recommend that you hold off on initializing the EMS until we get you the final pad. Over.

Okay. Will do.

Roger.

Okay, Houston. The sextant star check passes.

Houston, copy. Good show. That was some P52, Jack.

Yes. I was kind of lucky, I guess.

Give you a big gold star for that.

Thank you.

Hey, Joe. We're standing by to copy your new pad.

Okay, Jack. It'll be a few minutes yet. We want to get it right up to speed.

Okay. I can proceed with EMS check, can't I, Joe?

Odyssey, Houston. Over.

Go ahead, Houston.

Okay, Jim. Your CABIN is looking real good. We recommend you turn the SUIT COMPRESSOR to OFF now. Over.

Going OFF. Boy, it's nice and quiet in here.

Okay, real good. Incidentally, your power is looking real good also, Jim.

Thank you.

Odyssey, Houston. I have your final entry pad when you are ready.

Okay, Houston. Ready to copy.

Okay. Mid-PAC, 000152, 000; 142:38:19, 178; and you recall that's GET moonset and Moon-check attitude. NOUN 61, minus 21.66, minus 165.37; 05.2; 3621.1, 6.20; 1119.7, 36291; 142:40:46; 00:30; the next four are N/A; D_O is 4.00, 02:20; 00:19, 03:38, 07:59. The rest of the pad is N/A for this one. You are lift vector up at the very bottom. And the remarks all remain the same; if you want me to copy them, let me know; otherwise, you can read back. Over.

Okay. Entry pad as follows: Mid-PAC, 000152, 000; 142:38:19, 178; minus 21.66, minus 165.37; 05.2; 3621.1, 6.20; 1119.7, 36291; 142:40:46; 00:30; all the DLS are N/A. DO is 4.00, 02:20; 00:19, 03:38, 07:59. All the rest are N/A, except lift vector which is up; and I have the the …

Okay, Jim. That's a tiny hair shallower than we had you before, but it's based on solid tracking, and it still is lift vector up comfortably.

Roger. We never did bring that angle up, did we?

Odyssey, Houston. Over.

Go ahead.

Okay, Jack. We'd like P00 and ACCEPT for your final state vector.

You've got it.

And, Odyssey, Houston. We're also sending you a final PIPA bias update and clock increment. Over.

Okay. Fine; thank you, Joe. How does the LM look? Are you still tracking it?

All I've heard was that it's that the cabin was holding pressure. I haven't heard anything more. And, Odyssey, we're ready for you to warm up the BMAG number 2's at your discretion and we're curious whether the Moon check attitude is good. Over.

Yes, Joe, it's coming down. I got just about 45 degrees now and it's coming on down.

Odyssey, Houston. The computer is yours. Over.
