Spacelog Apollo 13

— you have plenty of water. I'm sorry we cut each other out; say again.

Okay, yes. I was going to say, understand we're going to go on the ascent tanks at 128:30.

That's right; based on the current rate, that's what they predict and you can go ahead and drink the water. No sweat.

Okay, real fine. And I've got the entry checklist out and I'm ready to copy; just give me the page.

Okay. Jack, you're starting to sound like an LMP.

I think I'm probably the only CMP that's ever witnessed an—a LM burn from inside the LM in—in space flight.

(Laughter) I hope it stays that way. Okay, Jack, we're starting on page 1-1.

Go ahead.

Okay, down in the middle of the page on line 9, we're just going to strike out the “Activate VHF for COMM checks,” and line 10, “Verify the DSE.” We're going to leave the DSE OFF, and that's to save power, as is the VHF activation.

Okay.

Okay, on page 1-2. At minus 2 hours, there's a title “Logic sequence” check; and we're deleting that entire sequence; that's included in what I read up to you.

Okay, delete the logic sequence check at minus 2 hours there.

That's correct. And delete lines 23, 24, and 25. That means a maneuver to SUPERCIRC entry attitude. Everything below that is deleted.

Okay. Delete lines 23 through 28.

That's correct. You got ahead of me. All right, on line 29 on page 1-3, we're going to put in a time of minus 00:55. That's the time we gave you for the boresight check.

Okay —

That's your sextant check, really.

Got that.

Okay, on the top of page 1-4; where it said “1 hour and 15 minutes” next to line 32, we're going to change that to “Minus 2 hours and 30 minutes.”

Okay, minus 02:30 opposite item 32.

Okay, down at the bottom of the EMS entry check right there where we are, the bottom line now reads, “EMS MODE to STANDBY.” Well, just above that—like to remind you to put a remark, “Do not initialize the range to go.” This is because you're going to come into the EMS entry check, you're going to run through all these things; then we're going to remove power from the EMS. And just didn't want you to get ahead of yourself and initialize the entry parameters, because you'll lose them when we power up.

Okay.

And, after we go EMS MODE to STANDBY, like for you to add “Circuit breaker EMS, two, to open.”

Okay, “CB EMS, two, to open.”

That's correct. And we want to delete this “Set up camera” that's listed on the bottom of the page. We're deleting that for power reasons. That's line 33 Alfa.

Okay, we're way ahead of you. We already got it stowed.

Okay. On the top of the next page where it says “Secondary water EVAP,” just keep in mind we don't plan to use the secondary evaporators unless the primary fails. On line 35 on page 1-5, next to “Command module RCS preheat,” the time is now “Minus 06:30.”

Okay, “minus 06:30,” and the voltage reading 3.9 still is good, right?

Okay, very good. Under “Final stowage,” the first thing that's listed on line 36, page 1-5, is “Optics.” And if you want to get started on your stowage, we'd like to leave the optics out, because we'll have the star check coming up quite a bit after this. The rest of that stuff can be taken care of at your convenience.

Okay.

All right, still on pace 1-5, line 37; the time is now “Minus 06:10.”

Got that.

Okay, and this is one time it looks like we might actually do the preheat, so that's the reason we want to make sure that we know that not more than 20 minutes of time on the preheat. We may not be able to watch it at that time because you aren't powered up.

Okay. Either 20 minutes or until 3.9 volts DC.

That's correct, Jack. And now let's go to page 1-6. And about one-third of the way down, it shows “Panel 275 CB MAIN A, BAT C, closed,” we want to strike off that line, the next two lines, and we're going to strike out “MAIN A, BAT C, closed; MAIN B, BAT C, closed; and DC INDICATOR, MAIN B.”

Okay. After that step on panel 275, strike out “CB MAIN A, BAT C; CB MAIN B, BAT C; and DC INDICATORS to MAIN B.”

That's correct. Now reader panel 8, it tells you to “Close all circuit breakers EXCEPT,” and I have four additions. The first one is CB SERVICE MODULE RCS HEATERS, QUAD Charlie, MAIN B, open.

SERVICE MODULE RCS HEATERS, QUAD Charlie, MAIN Baker, open.

Okay. And the same thing for SERVICE MODULE RCS HEADERS, QUAD Delta, MAIN A, open.

SERVICE MODULE RCS HEATERS, QUAD Delta, MAIN A, open.

That's correct. And Circuit breaker EMS, that's two of them, open.

Okay, BAT's at volts and amps.

That's affirmed. And let's go back to page 1-6, line 41. Let's put in a time “Minus 04:40.”

Minus 04:40.

That's correct. On page 2-1, line number 2, put in a time of “Minus 55 minutes.”

Okay, minus 55 minutes.
