Spacelog Apollo 13

Okay.

And AGS PULSE is the recommendation.

We're having trouble maneuvering, Joe, without getting it in gimbal lock.

Okay. You can —

You picked a lousy attitude, though, to separate.

Well, we apologize. Just take your time. Jim, we've got time now.

Okay.

Houston, why can't I stay in PGNS ATT HOLD for the LM attitude hold?

Stand by on that, Jim.

Aquarius, Houston. Over.

Go ahead.

Okay. Our recommendation is that you stay in AGS for the LM JETT simply because we've thought it through. We've got the right deadbands and all set up. Over.

Okay. It's a lot easier for me to maneuver in PGNS, Joe, than it is AGS.

Yes. You can maneuver in PGNS, Jim. I'm sorry, I thought you were talking about the ATT HOLD and the LM JETT afterward. You can maneuver in PGNS if you want to.

I want to get way over here, Joe. To prevent him into gimbal lock, I have the yaw at about—I'd say about almost 50 degrees.

Roger that. Just stay out of gimbal lock and that 45-degree isn't critical—the out of plane, that is.

Odyssey, Houston. Request OMNI Charlie.

Okay. Going OMNI Charlie.

Thank you.

There.

Okay. Good.

Roger. That's VERB 46. Roger. Aquarius, Houston.

Go ahead.

Okay, Jim. The particular DAP configuration we have set up now is using more fuel than we'd like out of system B. We'd like you to reconfigure the DAP to 30021. Over.

Thank you.

Odyssey, Houston.

Go ahead.

We'd like to have you turn the optics power off until you need them again, and we would like to have you check the RCS ring 1 and 2 temps for us. Over.

Optics power going off.

Okay.

Okay, Joe. Our ring 1 is 50; ring 2 is plus 42.

Ring 1 is 50; copy. What was the other?

42.

Got it. Thank you.

Okay, Houston; Aquarius. I am at the LM SEP attitude and I'm planning on bailing out.

Okay. I can't think of a better idea, Jim.

I'll go to AGS ATT HOLD, if you want me to.

We recommend that, Jim.

Okay, Aquarius; Houston. In AGS ATT HOLD, we recommend WIDE DEADBAND. Over.

I'm in the AGS DEADBAND.

Roger.

Aquarius, Houston. Don't forget the …

You need to relay something downstairs, Jim?

Odyssey, Houston.

Go ahead, Joe.

Okay. Our troops would like to have you go to the SYSTEMS TEST METER and read out the injector temps on RCS for us.

Okay. Okay. In work.

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.
