Spacelog Apollo 13

Okay.

My shorthand is rather poor today.

Okay I'm now up to circuit breaker panel 11, INVERTER 1, CLOSED.

Houston, 13. How do you read?

13, Houston. You're coming through. We still have some background noise. Do you want to read back step 7?

Hello, Houston; 13.

13, Houston. Go ahead.

Okay, Joe. The last thing I got was HELIUM MONITOR to SUPERCRIT PRESSURE.

Okay. The last part of step 7 is, “Report SUPERCRIT PRESSURE to MCC,” and read back step 7.

Okay. Step 7. Circuit breaker panel 11, AC BUS B, HELIUM PQGS DISPLAY, CLOSED. Main—Circuit breaker panel 11, AC BUS B, NUMERIC LIGHTING, CLOSED. CD panel 11, AC BUS—Is that AC BUS B? BUS TIE INVERTER 1, CLOSED?

That's affirmative.

And CB—CB EPS INVERTER 1, panel 11, CLOSED. CB panel 16, INSTRUMENT SIGNAL SENSOR, CLOSED. INVERTER 1, SELECT. HELIUM MONITOR to SUPERCRIT PRESSURE. Report pressure to MSFN.

Okay. That's correct. Now step 8 is, “On MCC request, perform step 9.” In other words, you wait for us to decide what to do and that's according to the gouge we've already given you. And step 9, I'll give you now, is “HELIUM MONITOR to OFF, INVERTER to OFF.” Over.

Okay. Step 8 says, “Set in an MCC hold.” Step 9 says, “On MCC' s words, HELIUM MONITOR OFF, INVERTER OFF.”

Roger. That's correct. Step 10 is, “Configure circuit breaker panels per Activation 3 and 4.”

Okay. Configure—step 10, “Configure circuit breakers per Activation pages 3 and 4.”

Roger. That's correct. Step 11 is, “Deactivate the utility lights if you activated them,” and step 12 which is the last one is, “Transfer to CSM power, usual observations, and report time to MCC.”

Okay. Step 11, “Deactivate utility lights.” 12, “Transfer to CSM power and note the usual observations and report the GET.”

Okay. That's it. And, of course, Houston will be requesting you to go to step 9 if the pressure is less than 770. If the pressure is between 770 and 800, we will be asking you to do the following, if you're ready to copy.

Okay. Go ahead with TLC-3.

Okay. Stand by 10 seconds, Fred.

Fred, Houston.

All right. Go ahead.

Roger. We'll hold off on that. It was a short three-step procedure which said, “Repeat activation pages 1, 1A, and 2,” but there was another step in it that nobody understands. So, essentially what we'd recommend in that case would be that you would repeat the procedure that we just passed up for reading the SUPERCRIT pressure. If we need to, we'll clarify it later on. And that's all we've got.

Houston, 13.

13, Houston. Go ahead.

Okay. One thing, Joe; I just want to doublecheck again. All the stuff that normally was going to start at 57 hours, which the first item was pressurize CSM to 5.7 psia, we're going to move that up to 64 now, so we have our LM entry which was nominally at 58 at 55. Is that correct?

That's correct, Jim.

Apollo 13, Houston.

Go ahead, Houston.

Roger, 13. Because of the O₂ tank 2 quantity sensor drop out, EECOM wants to keep a little closer track of the cryo quantities, and he's going to be asking you to stir all the cryo tanks at slightly more frequent intervals than had been planned, and the first time is now, and we will be calling you probably every 5 or 6 hours, except during sleep period and high activity periods. We'd like you to do it now. Over.

Okay. We'll start it … now.

Thank you.

Apollo 13, Houston.

Go ahead, Houston.

Jim, just an advisory; expect a CAUTION AND WARNING on H₂ tank 1 pretty quick. No problems; Just warning you about it.

Okay. A zero pressure light on H₂ tank 1 coming on shortly, huh?

Right.

Okay. Well, you're pretty close. It just came on.

Any other predictions you'd like?

Well, there's—I guess there's all sorts. Could you go to the horse races with me?

I'm sorry; you were garbled. Say again?

I said I'd like to invite you to the horse races with me.
