Spacelog Apollo 13

We're burning 40 percent.

Houston copies.

One hundred percent.

Roger.

Aquarius, Houston. You're looking good.

Roger.

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.
