Spacelog Apollo 13

Okay. CB LM POWER-2, MAIN B, open; CB LM POWER-1, MAIN A, open; CB EPS SENSOR SIGNAL, MAIN B, open. Stand by 1, Jack.

Jack, I don't think we ever closed CB LM POWER-1, MAIN A. We closed LM POWER-2, MAIN B, and LM POWER-1, MAIN B. Both of them on MAIN B.

Yes, you're right. Both of them should be MAIN B.

Okay. Copy that.

Okay. Ready to copy the LM?

Okay. Go ahead.

Okay. On panel 16 circuit breaker, EPS, BAT FEED TIES, two, open; and now you've got to listen real carefully for high volts and low volts, BATTERY 1, HIGH VOLTS, to OFF/RESET; BATTERY 2, LOW VOLTS, to OFF/RESET and then ON: BATTERY 2, HIGH VOLTS, to OFF/RESET and then ON; BATTERY 1, HIGH VOLTS, ON; and then the circuit breaker on panel 16, EPS: BAT FEED TIES, both of them, closed. Read back.

Okay. On the LM side of the house is on panel 16. CB EPS BAT FEED TIES, two, open; BATTERY 1, HIGH VOLTAGE, OFF/RESET; BATTERY 2, LOW VOLTAGE, OFF/RESET then ON; BATTERY 2, HIGH VOLTAGE, OFF/RESET then ON; BATTERY 1, HIGH VOLTAGE, ON. Panel 16, CB BAT FEED TIES, two closed.

Okay. That's a good readback. It concludes the procedure going both ways and now we just have to stand by.

Okay, when do you plan to start this?

Darn soon.

Did you say not soon?

No, we're going to do it pretty soon, but we want to have high bit rate, and we don't want you to give that to us until we tell you.

Okay. I think I'll go back and try to undamp up there. Do you have anything more for the command module?

We're discussing two items, but we don't have them ready right now.

One of them, I hope, is a foolproof alinement procedure.

Okay, Jack. Just for curiosity's sake, does FIDO have any information as to whether that helium—that helium tank dump affected our trajectory at all?

Okay, Aquarius. Our tracking data shows that since the helium dump, our entry angle has not changed from its value of 6.24 and somebody calculated that if we had a propulsive vent, that helium could roughly, at the maximum, only impart a DELTA-V of a half a foot per second or less, anyway. But we're continuing to track and as soon as we get some more info, we'll pass it along.

Okay. That's swell, Jack. Thank you.

Sure.

Your 6.24 sounds good.

I'm still awake, I guess.

Okay, Aquarius. We're ready. So we want some high bit rate. To do that, go over to panel 16 under COMM and close the PRIMARY S-BAND POWER AMPLIFIER. On your COMM panel -

Okay. Okay, Jack. Wait 1. While—I'd like to get the whole crew up for this if you don't mind.

Okay.

… they're ready to start. Yes, you want to get Fred-o up.

We want to transfer some power—I want to go to high bit rate here first, then want to transfer LM power to CSM, Fred.

Okay, Jim, I'll give you the COMM.

Aquarius, there's no great big rush. If you want to let Fred come up to speed slowly, why maybe that'll help out

Okay. …

And Houston, Jack is showing Fred the procedures before we start up.

Say again, Jim.

…

Aquarius, how do you read?

Loud and clear.

Okay. I'm hearing you now. I think I missed your last transmission, Jim.

Yes. I think if you add up the—Yes—if you add up the operating time, I think the LM beats the CSM by a considerable margin on this flight.

Grumman just hired you.

Yes.

You're out there at 134000, coming in at about 4900 feet a second.

Very good.

The SUPERCRIT tank went off at about 1937, just about like expected.

Yes. It—it also must of not did very much, except the rates. I was asleep then and I didn't hear a thing.

Is the command—service module still venting?

Jack said it was just before he went up. Right now, the Sun's over there, and I can't really tell —

And —

We asked him a long time ago if he was able to see any stars out the optics. I don't think we ever got an answer.

Okay.

That's a pretty good sleep station I had rigged up, Jack. I took one of the sleep restraints out of the command module, zipped up in it, and then hooked the tie, right at the top of the zipper, onto the LM upper hatch handle. So it kind of held me there, and then just drifted up in the tunnel upside down with my face toward the hatch, so the sunlight didn't get in my eyes and that worked pretty good.

Did you sleep pretty well that way?

Yes, no problem at all.

Is Jim sleeping that way now, or is he standing next to you?

He's standing next to me.

About time for him to go to bed.

Okay. The voltage upstairs is 34.3 and the charger is reading 2.5 amps.

Okay 34.3 and 2.5. And … says … —

— pretty cold. Good.

Say again your last.

They came—both came down here rubbing their hands, shivering. It's pretty cool upstairs.

Are you keeping warm in the LM?

Yes. It's pretty reasonable down here.

Okay. And right now, it looks like … right now, it looks like the command module isn't venting, Jack, so I'm going to try to take a look at the optics.

Okay. You say it is not venting?

Yes. That's the word. We've just looked through the AOT and you can't see anything back there.

Okay. And everything's fine in El Lago.

Very good.

Aquarius, we're ready to secure the high bit rate.
