Spacelog Apollo 13

And I just want to verify one thing, we could —

Yes, I'm sure —

— Go ahead.

I say I'm sure glad we didn't have a LM impact, too.

Right. Just wanted to verify—We had poor reception when I was talking to you before—I wanted to verify that you understand that the Sun check you made earlier in the AOT was good, and that's what we're riding on. Anything that we told you in the past about looking at the Sun in the front left window or looking at stars, like Nunki through the AOT, why, we want to forget.

Roger. Understand, Vance. I think Nunki would be kind of hard to see anyway with the Moon right here.

Right.

And, Vance, we plan to start powering up at 78:12. Is that a good time or do you think we ought to hold off a little longer?

Jim, we think that's very good.

Apollo 13, Houst—Aquarius, Houston.

Go ahead.

Fred, after the burn, we'll get the powerdown instructions, or checklist changes to you. At the same time, we'd like to get a consumables status to you. All I'll say right now is that we think you look in reasonably good shape.

Okay. Very good.

Okay. Houston, Aquarius.

Go ahead.

Okay. One CAUTION AND WARNING light here showing that you didn't call out—it's the PRE AMPS—I suppose because we don't have the ATCA breaker in yet.

Houston, are you planning to give us a state vector update.

That's—That's affirm, Jim. All we need is UPDATA LINK circuit breaker closed on panel 11, and P00 and ACCEPT and we can ship it up to you. P00 and DATA.

Okay, Vance. We're in DATA and P00 and the circuit breaker's in. Go ahead.

Aquarius, Houston.

Go ahead, Houston.

Jim, request verify RANGING FUNCTION switch is in RANGING. We need that, if it's not there now.

You got it, Vance.

Thank you.

Aquarius, Houston. Did you call?

We didn't call, Houston.

Okay.

Aquarius, Houston. Over.

Houston, are you calling Aquarius?

Roger, Fred. I would like to confirm that you are getting drinking water out of, potable water out of the command module and, if you can make any estimates of how much you use as time goes on, and how much you have used, we would appreciate it for our consumables analysis.

Okay.

Okay, Jack. Tried the procedure and out of that pressure, we got 10 drinks made. That's roughly 80 ounces.

Okay, Fred, we had a little static on that one, but I think you said that 80 ounces of water has been used out of the CM. Is that right?

Yes. Jack worked the procedure and filled as many of the drinks as he could, and he made up ten bags of approximately 8 ounces a bag.

Aquarius, Houston.

Go ahead, Houston.

Jim, just a bit of information, if for any reason you had to slip T_ig, our people here feel it wouldn't do much harm if you slipped it up to 30 minutes. The procedure, of course as you know, is not to PRO on the flashing 99 and we thought you might like to be aware that T_ig time isn't all that critical.

Okay, Vance; Aquarius.

Go, Fred.

Houston copies.

One hundred percent.

Roger.

Aquarius, Houston. You're looking good.

Roger.

Aquarius, you were looking good at 2 minutes. Still looking good.

Two minutes. Roger.

Aquarius, you're GO at 3 minutes.

Aquarius. Roger.

Don't forget DESCENT REG 1, off; 10 seconds to go.

SHUTDOWN.

Roger. Shut down.

Are you reading our 1640, Houston?

Roger. We're reading it.

We'll proceed. Here's our residuals.

Roger. Very small.

Good burn, Aquarius.

Go ahead.

I say, that was a good burn.

Roger. And now we want to power down as soon as possible.

Roger. Understand.

Houston, Aquarius.

Go ahead.

Suggest maybe you just read off the circuit breakers you want us to power down. As you did yesterday, for us.

Okay. We have a procedure ready to send up to you here in about 2 minutes. Let us know when you're all ready to take it.

Okay.

Okay. Is it going to be better to write this on a blank page, Vance, or can we use some portion of the powerdown list there in the contingency book that already exists.

Stand by 1.

Aquarius, Houston. Over.

Go ahead.

Slight delay here, Jim. It will be a couple of minutes before we read that up to you, and we're looking at the contingency checklist powerdown and that's on page 5. You might be getting that out while we get all ready to give it to you.

Could you give us that page number again. Page 5 doesn't make sense.

Okay. Make that power 5 in the contingency checklist, Fred. And it's the —

— that's better.

— middle part of the page, it starts emergency powerdown, and we'll mark that up.

Okay. I'm to 5 emergency powerdown.

Okay. But hold off on it because we might have to start PTC up again here. And that's the point that's being resolved right at the moment, so stand by.

Aquarius, Houston. Over.

Go ahead, Houston.

Okay. We're ready to give you the procedure which will power you down a good bit, and after the PTC is going, maybe we can give you further information, are you ready to copy? Starting at the middle of the page, power 5.

Okay. Go ahead, Vance.

Okay. After number 1, first line, cross out “And VHF-A.” Second line, cross out “SIMPLEX operation.” Third line, cross out “Prime.” That refers to PRIME POWER AMP, OFF. That—that “PRIME” should actually be replaced by OFF. And that's the second prime that line. Also in the third line the last word “OFF” should be crossed out and replaced by “PCM.” Fourth line is okay. Fifth line, which is “VHF VOICE, ON, OFF, OFF,” cross out. “Lighting, FLOODS,” which is the next line should be “OFF”, but add the following, “Or OVERHEAD/FORWARD prefer OFF.” Okay. Step 2 remains the same; no change for the moment. Stand by. Skip step 2. Do not do it. Just go on to step 3, which is “Configure circuit breakers per the chart.” That takes us to page power 6. Why don't you give me a readback on what you had on power 5, Fred-o.

Okay. On power 5, emergency powerdown. Item 1, first line, I scratch the “And VHF-A.” Second line “SIMPLEX operation.” Third line, I replace the second prime which is the POWER AMP with an “OFF,” and the last word in that line is “OFF,” replaced it with “PCM.” Fourth line is okay. Fifth line, I scratch the whole line. Lighting, we haven't needed floods yet so we will just leave them off, exterior lighting off. Scratch line 2 and I am now on power 6, wait for your update on the CB panels.

Okay. I disagree on the fifth line. It appears that we ought to have the ASCENT ECA CONTROL open.

Okay. We'll check into that one and while we are listening to the rest of your readout.

Okay. And top row is correct as is. Second row we want the QUAD TCAs 1 through 4 closed. On the third row, we want the ATCA (PGNS), closed. On the fourth row we want the PGNS LGC DSKY, IMU STANDBY, IMU OPERATE, all closed, and you're saying the bottom row as is.

Okay. We'll go along with what you said on the ASCENT ECA CONTROL. That should be open.
