Fred Haise (LMP)

Key moment "Houston, we've had a problem.": Okay, Houston —

Jack Swigert (CMP)

I believe we've had a problem here.

Jack Lousma (CAPCOM)

This is Houston. Say again, please.

Jim Lovell (CDR)

Houston, we've had a problem. We've had a MAIN B BUS UNDERVOLT.

Jack Lousma (CAPCOM)

Roger. MAIN B UNDERVOLT.

Jack Lousma (CAPCOM)

Okay, stand by, 13. We're looking at it.

Fred Haise (LMP)

Okay. Right now, Houston, the voltage is—is looking good. And we had a pretty large bang associated with the CAUTION AND WARNING there. And as I recall, MAIN B was the one that had had an amp spike on it once before.

Fred Haise (LMP)

In the interim here, we're starting to go ahead and button up the tunnel again.

Fred Haise (LMP)

Yes. That jolt must have rocked the sensor on—see now—O2 QUANTITY 2. It—was oscillating down around 20 to 60 percent. Now it's fullscale high again.

Jim Lovell (CDR)

And, Houston, we had a RESTART on our computer and we had a PGNCS light and the RESTART RESET.

Jack Lousma (CAPCOM)

Roger. RESTART and a PGNCS light. RESET on a PGNCS, RESET —

Jim Lovell (CDR)

Okay. And we're looking at our S—SERVICE MODULE RCS HELIUM 1. We have—B is barber poled and D is barber poled, HELIUM 2, D is barber pole, and SECONDARY PROPELLANTS, I have A and C barber pole. BMAG temperatures?

Fred Haise (LMP)

Okay, AC 2 is showing zip. I'm going to try to reconfigure on that, Jack.

Fred Haise (LMP)

Yes. We got a MAIN BUS A UNDERVOLT now, too, showing.

Fred Haise (LMP)

It's reading about 25-1/2, MAIN B is reading zip right now.

Jim Lovell (CDR)

And, Houston, Odyssey.

Jack Lousma (CAPCOM)

13, Houston. We'd like you to attempt to reconnect fuel cell 1 to MAIN A and fuel cell 3 to MAIN B. Verify that quad Delta is open.

Fred Haise (LMP)

Okay, Houston. I'm showing—I tried to reset and fuel cell 1 and 3 are both showing gray flags, but they are both showing zip on the flows.

Fred Haise (LMP)

Okay, Houston. Are you still reading 13?

Jack Lousma (CAPCOM)

That's affirmative. We're reading you. We're trying to come up with some good ideas here for you.

Fred Haise (LMP)

Okay. Let me give you some reading … in the interim to help MAIN A voltage, Jack. I've got BUS TIE AC on.

Fred Haise (LMP)

In the interim, to help out MAIN A voltage, I've got MAIN BUS TIE BAT AC on. Or would you rather accept the 25 volts we are seeing on MAIN A?

Jack Lousma (CAPCOM)

13, Houston. We need OMNI Charlie, please.

Jack Lousma (CAPCOM)

13, Houston. We'd like you to verify couple of readings for us. We would like the nitrogen pressure on fuel cell 1. We need the oxygen pressure on fuel cell 2.

Fred Haise (LMP)

Okay. Nitrogen on 1 and oxygen on 2. Is that correct?

Fred Haise (LMP)

Okay. The systems test 1-A says zip.

Fred Haise (LMP)

And 2 Baker, which is 3 oxygen, says 0.6.

Jack Lousma (CAPCOM)

2 Baker says 0.6, and say again the other one.

Fred Haise (LMP)

Fuel cell 1 nitrogen reads zero.

Jack Lousma (CAPCOM)

13, Houston. We'd like you to open circuit fuel cell 1; leave 2 and 3 as is.

Fred Haise (LMP)

Okay. I'll get to work on that.

Jim Lovell (CDR)

And, Jack, our O2 quantity number 2 tank is reading zero. Did you get that?

Jack Lousma (CAPCOM)

O2 QUANTITY number 2 is zero.

Jim Lovell (CDR)

That's AC, okay. Yes, that's good AC and it looks to me, looking out the hatch, that we are venting something. We are venting something out into the—into space.

Jack Lousma (CAPCOM)

Roger. We copy your venting.

Jim Lovell (CDR)

It's a gas of some sort.

Fred Haise (LMP)

Okay. Fuel cell 1, you just wanted it off the line now, Jack, is that right?

Jack Lousma (CAPCOM)

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

Fred Haise (LMP)

Okay. She's off the line.

Jack Lousma (CAPCOM)

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.

Jack Lousma (CAPCOM)

13, Houston. Do you read?

Jack Lousma (CAPCOM)

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

Fred Haise (LMP)

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

Jack Lousma (CAPCOM)

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

Jack Lousma (CAPCOM)

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.

Jim Lovell (CDR)

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

Jack Lousma (CAPCOM)

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

Jack Lousma (CAPCOM)

13, Houston. Did you copy our powerdown request?

Jack Swigert (CMP)

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

Jim Lovell (CDR)

Where did you say that was located, Jack?

Jack Lousma (CAPCOM)

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

Jack Lousma (CAPCOM)

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 —

Jack Swigert (CMP)

Okay. That was in the launch checklist, Jack.

Jack Lousma (CAPCOM)

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

Fred Haise (LMP)

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

Jack Swigert (CMP)

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.

Jack Lousma (CAPCOM)

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

Jack Swigert (CMP)

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?

Jack Lousma (CAPCOM)

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

Jack Swigert (CMP)

It's negative pitch and negative roll.

Jack Lousma (CAPCOM)

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

Fred Haise (LMP)

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.

Jack Lousma (CAPCOM)

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

Jim Lovell (CDR)

FUEL CELL 2 to AC1. Roger.

Jack Lousma (CAPCOM)

OMNI Charlie, please, 13.

Jack Lousma (CAPCOM)

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.

Fred Haise (LMP)

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.

Jack Lousma (CAPCOM)

Roger. We'll give you an answer.

Fred Haise (LMP)

Or, if necessary, to use the LM consumables.

Jack Lousma (CAPCOM)

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