Spacelog Apollo 13

And, Joe, do you have the … out for the …?

I'm not sure I copied that, Fred. If you asked me whether I had that powerup procedure, I don't have it for you, yet. Over.

No. The question was, do you have a … from the Moon burn.

Still didn't understand, Fred. I'm sorry.

Okay. We'll be able to get better COMM.

Roger.

Okay.

Fred, Houston. You want to try it, now?

How do you read, Houston?

That's pretty good, Fred.

Okay. Two things: first of all, we noticed a …

Gol darn it. Just as you started talking, it got noisy again, Fred; try it again.

Okay.

Try it now, loud and slow.

Okay. Jack had a question on how far out from the Moon are we now?

On how far out what?

From the Moon we are now?

Oh. Our little plot shows you just touching the 180-thousand-mile line. So you're about 40 K out from the Moon.

Okay. Okay. And the other thing is, we've noticed some fresh new particles floating around outside, so possibly the service module is starting to vent a little bit again.

Okay. Copy that, Fred. On the O₂ flow thing, we clearly saw the DEMAND REGULATOR go to OFF and back to CABIN. TELMU thinks that it's no big thing that you've seen a little change in flow due to the different resistance we've got in the circuit.

Roger.

Aquarius, Houston.

Go ahead.

Okay, Fred. Recommend you go to OFF on the BIOMED switch. We never did get any BIOMED and it might clear up the COMM a little bit.

Okay. How you read now?

Okay, Fred. That might be a little better.

We're on the 180—K line, right now.

…?

We're about 40 050.

… It's 550 over there.

Okay. It's … there.

Just split the difference.

Yes.

Okay. I got a copy of the … K …

Is that right?

EECOM.

That midcourse should be interesting. You know, the mode we're going to do it in.

Manual AGS … DPS burn. We're controlling … TTCA attitude. …

… down under …

Fortunately.

We can't help them too much. Actually it isn't bad … but … … goddamned unfortunate. In part, I get a feeling … now when I get … Just before … goes to zero in 1 second I'm going to pull them out …

Another burn that's never been done.

Go to the—Go to the technique for a lash and … it's the burn technique.

I'm sure they got something written out, maybe …

A what?

Well, hell, Jack. All you—you don't use a very good one … Just if you'll go … at your attitude reference for … and the g-meter backup. Because, really, you can almost … The command module and your odds are 60 to 40 that you're going to hit Earth blunt-end first, without any reference.

… I didn't realize that. That proves you've got a little bit above 50-percent odds that you're going to enter blunt end, and -

We made an entry like that in Apollo 8 in a … with Houston, ol' Buzz went and turned on the command module heaters and left them on. The activators, they went, “Shooo!” both tanks; we had no gas. Just had a real slow rate … We actually went out in the console and started debriefing, but left it running and watched it; and the son of a bitch did a hop-skipout, a hopout, underneath …, but not much, and then we did a long hop … but—The second reentry, also, it did one … both times. It lucked out twice and made a real peculiar … They went to zero g …

Yes.

Hey, Aquarius; Houston. How do you read me?

Aquarius, Houston. Okay. Go ahead.

Okay, Joe. It—Our wobble in this PTC has picked up where the Moon is running by pretty high in the window and the Earth pretty low; so I expect—On the side where the Moon's present, we're having a little bit of trouble with the COMM … breakout there in a couple of places.

Okay. Roger that, Fred.

… pressure gage as far as the noise … get the thing from the AFT. …

Houston, Aquarius.

Aquarius, Houston. Go.

Okay, Joe. I'm all set to copy that procedure for powering up the command module from the LM, whenever you want to give it to me. When did you, I guess you want to put battery A out of the CHARGE, huh?

Jack, we're not certain when the best time is to implement this procedure, and what we want to do at this time is read it up to you, so you'll have it and understand it and we'll—We'll be able to do it quickly when the time comes. And I don't have it for you quite yet. Over.

(Laughter) Okay. All right. I'll be standing by to copy it whenever you get it.

Okay, Jack.

Aquarius, Houston. Over.

Joe, I got to switch antennas here. Okay, Joe, I read you on the FORWARD antenna.

Okay, Jack, I have the procedure now to read up to you. Before I do, I want to mention something that will be of interest to Fred. We are looking at the SHe tank pressure rise and we expect it to blow. We don't know exactly what time it will go, somewhere around 105 hours or perhaps later than that. We've got plenty of blowdown capability. We just thought you ought to be informed.

Okay. Stand by. I'll tell him, now.

Okay.

Fred, they said they're looking at the SHe tank pressure rise, and they expect it to blow somewhere around 105 hours … Okay. Fred thought they did. …

Okay. Real fine. Are you ready for the procedure, now, Jack?

Yes. Joe, how long is it? Is it a big long one, or a short one, or a medium sized … about how many pages?

It's about—I'd say 15 to 20 steps, Jack. Some of it is LM stuff, and the rest of it is in CSM.

Okay. I got a fresh page here, and I'm ready to copy.

Okay. I'll give you the LM steps first. They have to be done first, and the first step is on panels 11 and 16, circuit breakers ASCENT CA, ASC ECA, two to close.

Okay. Panels 11 and 16 CBs ASCENT ECA to closed.

Okay. Next step: panels 11 and 16 CB ASCENT ECA CONTROL, two, to close. Over.

Okay. On 11 and 16 CBs ASCENT ECA CONTROLs to close.

Okay. That's correct. The next step is BAT 5 and 6 NORMAL FEED to high; those are switches.

Okay. BATs 5 and 6 NORMAL FEED, ON.

That's correct. Next step: BATs 1 and 3 to OFF slash RESET. Over.

BATs 1 and 3 to OFF slash RESET.

That's correct. Next step: wait 30 minutes for preconditioning.

Okay. That's wait 30 minutes for preconditioning.

That's correct, and the last LM step for now is BATs 2 and 4 to OFF/RESET.

Okay. BATs 2 and 4 to OFF/RESET.

That's correct. Now we'll go to the CSM, and the first step there is connect LM/CSM umbilical. Over.

Okay. Connect LM/CSM umbilical.

Okay. The next step, on panel 5, CB LM POWER-1 MAIN B and LM POWER-2 MAIN B, both, closed. Over.

Okay. On panel 5, CB LM POWER-1 MAIN B and 2 MAIN B, both, closed.

That's correct. On panel 5, CB EPS SENSOR SIGNAL MAIN B to close. Over.

EPS SENSOR SIGNAL MAIN B closed on panel 5.

That's correct. Next step, panel 250: CB BAT C POWER ENTRY/POSTLANDING; closed. Over.

Okay. On panel 250: CB BAT B POWER ENTRY/POSTLANDING, closed.

That's Charlie. Verify MAIN BUS voltage; then, LM POWER switch on panel 2 to CSM. Over.

Okay. That's verify the MAIN BUS voltage, and switch LM POWER to CSM.

Okay. That's correct. Then go back to 275, CB MAIN B BAT BUS B to open. Hey, Jack, that's the step I skipped for you, I'm afraid. Before verifying MAIN BUS voltage, you have to, on panel 275, close CB MAIN B BAT BUS B. Over.

Okay, Joe. How are you reading on the AFT OMNI.

You're okay now. Go ahead.

Okay. After putting the BATTERY B POWER ENTRY/POSTLANDING on, then I want to push the—on panel 275 MAIN B to BAT BUS B in, huh?

That's right. Then you go to verify MAIN BUS voltage, LM POWER to CSM, and then, on panel 275, circuit breaker MAIN B BAT BUS B to open. Over.
