Spacelog Apollo 13

Okay. That's all for the time line, Fred. Now the contingency checklist, if it's handy.

Okay. Which page?

Turn to 30-minute activation on page 24.

Okay. I'm there.

Okay. Now, at this point, you have this section marked up already, so what I give you now represents additional DELTAs to your previously marked up checklist.

Okay. That's all right. I've got a different color pen, so it'll show up nicely. Go ahead.

Okay. Okay. Go down to item 4.

Roger.

Verify ACS STATUS switch, OFF. That's an addition.

Do you mean, under IVT to the LM, number 4, RCS SYSTEM A/B-2, QUADs 4, AUTO? That 4?

That's affirm. Yes. It's the—the only 4 on that page 24 and it's a—presently has after it RCS SYSTEM A/B-2, QUADs, 4, to AUTO. Under that put —

Roger.

— put verify AGS STATUS switch to OFF.

Okay. Verify AGS STATUS switch OFF.

Okay. At the bottom of the page—Okay. You already have that. MODE CONTROL, both, OFF.

Okay. Next, page 26, circuit breakers.

Okay. Go ahead.

Okay. First row is okay as is. Second row, under FLIGHT DISPLAYS, GASTA should be closed.

Okay.

Under AC BUS A, close GASTA.

Okay. GASTA FLIGHT DISPLAYS and AC BUS A will be closed.

Roger. That's all on the second line. Now the third line, under STABILITY and CONTROL, ATCA (PGNS) to closed.

Okay. ATCA (PGNS) to close.

That's all on that line. Fourth line, near the right side, LGC STANDBY to close. And —

Wait a minute. You mean LGC/DSKY.

LGC/DSKY. I'm sorry.

Okay.

And IMU OPERATE, close.

Okay. IMU OPERATE, close.

Okay, Vance. IMU OPERATE, close.

That's correct. Okay. Fourth row is okay as is. Now we would like to add—add in a late arrival to row two. Under —

Go ahead.

Under FLIGHT DISPLAYS, MISSION TIMER, closed.

Okay. FLIGHT DISPLAYS, MISSION TIMER, closed. We can look at the ghosties right to the end.

Yes, that's right. Okay. That's all for that page, Fred. That should add up to six circuit breakers all closed, on that page.

Vance, Jim.

Go ahead, Jim.

Have we looked seriously now at just the essential things required to make a safe LM jettison? We're not—I don't think we have the time to really do any engineering data that people might want to look at as this thing goes into the atmosphere.

Well, Jim. I—I think that that was what everybody aimed for, and people down here feel that it's the essentials, that it's what you need.

Well, we'll do everything you think is essential, but I just don't want to be throwing switches at the last minute. What we're really thinking about, getting that command module in good shape.

Hey, Jim. This is Tom. The only reason we're bringing up the PGNS is to have another reference system just to control the LM when you jettison the thing. Over.

Okay. Okay, Tom. It's—I thought the—an AGS ATT HOLD would have been sufficient for this, when we first thought about this.

Yes. I agree. But we decided just in case we have any glitch with the AGS, we want to make sure we get that LM off in a good shape. And I agree with you on keeping out all the garbage on it.

Okay, Tom.

Hey, would you like to have —

Good night.

Okay.
