Spacelog Apollo 13

We just wanted you to open the circuit on fuel cell 1.

13, Houston. We see you getting close to gimbal lock there. We'd like you to bring up all quad Cs on MAIN A, quad C-1, C-2, C-3, C-4 on MAIN A, and also bring B-3 and B-4 up on MAIN A.

13, Houston. Do you read?

Yes. We got it.

Affirm.

Okay. Can you tell us anything about the venting, where it is coming from, what window you see it at.

It's coming out of window 1, right now, Jack, and could you give me the thrusters again?

Okay, the thrusters —

We'd like—on MAIN A, we'd like Charlie 1, 2, 3, and 4. Also Bravo 3 and 4 on MAIN A.

Okay. Got it.

13, we need OMNI Bravo.

OMNI Bravo.

Okay, 13; this is Houston. We'd like you to go to your G&C checklist, the pink pages, 1-5. Do powerdown until we get a Delta of 10 amps. Over.

All right. Roger.

Okay, Jack, say again that—… for the powerdown; it's not in the pink pages, the 1-5.

Okay. We'd like you to go down that powerdown procedure until you get a Delta of 10 amps. Over.

Roger. …

13, Houston. Did you copy our powerdown request?

Roger, Jack. We're—yes, we're doing it right now.

Where did you say that was located, Jack?

That's in your systems checklist, page 1-5.

And, 13, you might also check for those pages in your launch checklist. They're emergency pages; pink pages, 1-5, and we'd like you to power down until you get —

Okay. That was in the launch checklist, Jack.

Roger. Power down until you get an amperage of 10 amps less than what you got now. Over.

Okay. Jack. Are you happy with the amps we have now?

Stand by 1, Fred.

Okay, Jack, and on this page 1-5, we proceeded right down the list, all the way down; we're right now at BMAG number 2 is in WARM UP.

Roger. We copy BMAG 2 in WARM UP. We'll follow you through.

Okay, and something is giving us a reach, Jack, both in pitch and roll, so I'm suspecting that maybe it's whatever it is that's venting back there. I've had to use DIRECT in order to stabilize this, and as soon as I do, we're starting to pick up rates again. Can you pick up any jets firing?

Stand by. What direction are your rates in, Jack?

It's negative pitch and negative roll.

Roger.

13, Houston. We need to get some more instrumentation up. We'd like you to put INVERTER 1 on both AC BUSES. Over.

Okay. Okay, you got INVERTER 1 on both AC BUSES now. And Jack, one of the items that we turned off was the—all the fuel cell pumps. Okay, and you might let us know when fuel cell 2 needs its pump back; we ought to take care of that guy.

Roger. Okay, Fred, we want FUEL CELL 2 PUMPS to AC1, please.

FUEL CELL 2 to AC1. Roger.

Okay, it's on AC1.

OMNI Charlie, please, 13.

OMNI Charlie.

Okay, 13. We've got lots and lots of people working on this; we'll give you some dope as soon as we have it, and you'll be the first one to know.

Oh, thank you.

Okay, Jack, and the weird configuration we're sitting in now is we have the hatch installed, we still have the probe and drogue inside the command module, and we're going to stay in this situation until you—kind of give us an okay to reinstall the probe and drogue.

Roger. We'll give you an answer.

Or, if necessary, to use the LM consumables.

13, we'd like to have you put thruster Alfa 3 on MAIN A, please.

Alfa 3 on MAIN A.
