Spacelog Apollo 13

Jack, we're going to give you three coarse aline angles, and then you can go right to your checklist as we're giving it, and start in with the VERB 40 NOUN 20.

And, Jack, how do you read?

Fine—square.

I was around shooting pictures of all the debris inside here, before we left, and I inadvertently changed the settings on the DC command module Reseau camera that we need for the service module pictures. I wonder if FAO can dig them out again—what we need, f-stop and speed.

Okay, Fred. Stand by.

Fred, in regards to the camera settings, for black-and-white 3400 film, the settings were f:5.6 at 1/250th. Over.

Aquarius, Houston. Over.

Go ahead, Houston.

Okay, Jim. I got MCC-7 pad when you're ready to copy. Over.

Okay. Stand by.

Okay. We're in luck, I got one pad left.

Okay. We'll take care not to change this one. Ready to go?

Go ahead, Joe.

MCC-7: 137:39:48.39, minus 0003.1, plus all zeros, plus 00001, N/A, plus 0020.5, 0003.1, 0:23, 008, 359; the rest is N/A. Remarks: plus-X, four jets, RCS; and your weights for the DAP load: LM weight, 25181; CSM weight, 62468. Over.

Okay, Joe. MCC-7: 137:39:48.39, minus 0003.1, plus all balls, plus 0000.1, N/A, plus 0020.5, plus 0003.1, 0:23, 008 359; the rest of pad N/A. Remarks: plus-X, four jets, RCS, ullage; the LM weight, 25181; CSM weight, 62468. Over.

Okay. Readback correct.

And, Aquarius; Houston. I have a service module SEP pad if you want to copy that, now. Over.

Say again, Joe.

Roger, Fred. I have a service module SEP pad with the attitudes. You don't need a pad sheet for it; just any old blank sheet will do.

Okay. I was going to say I don't—We don't hardly carry a service module SEP pad.

Yes, we'll have to change that.

Okay. I'm using a P27 here. Go ahead.

Okay. The pad reads as follows and then I'll repeat the angles for you, so you can copy them. The following MCC-7, maneuver the LM to the following FDAI attitudes: roll, 000; pitch, 91.3; yaw, 000. Now do you want those attitudes repeated, Fred?

Okay. Following MCC-7 we're to maneuver to the following attitudes: roll, 000; pitch, 091.3; yaw, 000.

Okay. That's correct. And the last part of the pad is at GET 138:10:00, which is EI minus 4.5 hours, execute a push of 0.5 feet per second, four jet, plus-X; perform SM SEP; then execute pull, 0.5 feet per second, four jet, minus-X. Over.

Houston, Aquarius. Jack's entering the command module, now.

Okay, Jim.

Okay. That last Joe was execute at the GET at 138:10:00 which is EI minus 4-1/2 hours; execute a push of 0.5 feet per second, four-jet ullage; then execute SM SEP followed by a pull of 0.5 feet per second, with respect to a nomenclature on the TTCA; I think we really need an up of 0.5 and then a down of 0.5.

That's correct, Fred.

Okay, Aquarius. The last pad I had for you right now is the LM jettison pad. Similar to the—Stand by 1, Aquarius.

Okay, Aquarius; Houston. Request P00 and DATA for a data load. Over.

You got it.

Okay. And I was about to say the LM jettison pad is similar to the SM SEP pad, Fred, when you're ready to copy.

Just about the same number of lines?

Yes.

Okay. Go ahead, Joe.

Okay, Fred. Prior to 141:40:00, which is EI minus 1 hour, maneuver the LM to the following FDAI angles: roll, 130; pitch, 125; yaw, 012.4. The corresponding CSM gimbal angles will be roll, 291; pitch, 196; yaw, 045, and that's the pad. Over. And the computer is yours, Aquarius.

Thank you.

Okay. A LM SEP pad prior to 141:40:00, EI minus 1 hour, maneuver to following attitudes: roll, 130; pitch, 125; yaw, 012.4. The corresponding CSM gimbal angles are roll, 291; pitch, 196; yaw, 045.

Readback correct.

Aquarius, Houston.

Go ahead, Joe.

Okay. We're so efficient down here that we got an entry pad ready, Fred. Do you want to copy that for Jack? Over.

Stand by. I'll have to try to borrow his book from him.

Roger.

Can we hold off on that a little bit, Joe?

Oh, absolutely, Jim. We're well ahead. I just wanted to let you know that we had it.

Okay. I hope that when you send up all those uplinks to Jack that you could get them up to him quickly.

We're shooting for less than 5 minutes.

Sounds good.

And are you still using the computer?

That's a negative, Fred. The computer is yours.

And, Fred, the computer has your target load in.

Okay.

Houston, Aquarius.

Go ahead, Aquarius.

Okay. I just want to clarify one thing on the LM SEP pad. It appears to me that in my configuration, I could probably use a VERB 49 loading in 622, yaw, pitch, and roll, in that order; and then being able to fly out at 5018 in roll, pitch, and yaw. Is that correct?

Stand by; I'll verify it, Jim.

Okay, Joe. And while you're doing that I've got a question about the command module checklist.

Okay, Jack. Go ahead with your question.

Okay. Either I copied the circuit breaker wrong, or—I can't read it. Comes down just about the—oh, about the 20th one down, after panel 276, where it says CB INSTRUMENTATION POWER CONTROL 3 and 4, open. The next circuit breaker on panel 5—I—Would you give that to me again?

Roger. That's CB ESSENTIAL INSTRUMENTATION POWER, MAIN B. Over. And it's, closed.

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

That's affirmative.

Aquarius, Houston.

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.
