Spacelog Apollo 13

Okay. I just can't, right—I just can't read my writing, ESSENTIAL INSTRUMENTATION POWER MAIN B, closed.

That's affirmative.

Go ahead, Joe.

Roger. The word we have is that you can't make a VERB 49 maneuver to the LM jettison attitude because those are FDAI angles we gave you, they don't correspond to the gimbal angles for the load; it'll have to be a manual maneuver. Over.

Okay.

And mind out for gimbal lock.

Aquarius, Houston.

Go ahead, Houston.

Roger. We're looking at LM current, to see if Jack has started his preheat, and we haven't seen it yet. Is he doing okay down there?

Houston, Jack said he's already started it, and he said that in 1 more minute, he'll be up to 20 minutes.

Oh. Roger that.

Jim, Houston. Have him let us know what his test meter reads when he's done.

He says that he had a battery A voltage drop of 2 volts, and he'll try to look at the test meter for you right now.

Okay.

He's been looking at them, but they haven't been coming up, so far.

We copy.

Do you see a current now, Houston?

Stand by 1 on that, Jim. That's affirmative, Jim; it looks like we are seeing one now.

Okay. And thanks for keeping us on it.

Aquarius, Houston.

Go ahead.

Roger. Reminder P41 for the RCS burn.

Thanks for keeping us honest.

We got to protect our jobs, Jim.

We've been DPS-ing so long here.

Okay, Houston. I finished up the maneuvers, the AUTO maneuver in 41, but only roll and yaw needles seem to be offset. Pitch is okay.

Okay, Jim. We copy. Stand by. Aquarius, Houston. We recommend PGNS MODE CONTROL to ATT HOLD. Save a little gas and stand by on the error needles.

Houston, Aquarius.

Aquarius, Houston. Did you call?

Roger, Joe. Figured, if we're going to do this burn in PGNS now, I ought to give you an update on the contingency book pages 32, 33, and 34, because the last time we went through this portion, we were burning it in ACS.

Okay, Fred. Stand by. We've been talking about possibly having you do it in ACS. We recommend at this time that you do an ACS to PGNS aline, the 400 plus 3 procedure only. Over.

Okay.

And, Aquarius, Houston

Go ahead, Houston.

Roger. We recommend that you perform this burn in AGS, as you did the last midcourse manuever; we think it will save gas. Over.

Okay. Joe, do you want me to line up the same way we did the last one, too?

Stand by on that.

And, Joe, Jack just handed me some injector temperatures, if you want to read these on … so I can plug them in.

Roger. Go ahead with those.

Okay. 5 Charlie, 14.0; 5 Dogs, 3.7; 6 Able, 3.5; 6 Bravo, 4.1; 6 Charlie, 4.2; 6 Delta, 3.8.

Okay. Copy those, Fred.

Aquarius, Houston.

Go ahead, Houston.

Okay, Jim. Our recommendation on this burn is that you maneuver to the burn attitude, in PGNS MIN IMPULSE, then do a body-axis aline, 400 plus 5, followed by 400 plus 0, and then do the burn in AGS. Over.

Okay. Now we're spinning it with the PGNS, what you gave us for a PGNS attitude. Is this the wrong one? Do you want me to just to aline up the Earth as I did before in the last midcourse?
