Spacelog Apollo 13

Okay. Okay. We want back in again the next step which is “At burn attitude: VERB 40 NOUN 20, ENTER.”

Okay.

Okay. Proceeding on down, delete “At burn attitude” and the step above it, which is 400 plus 5.

400 plus 5 and the “at burn attitude.”

Correct.

Okay. That's all for page 32, Fred. Next, page 33.

Go ahead.

Okay. Under 4 minutes, minus 4 minutes, add back in MODE CONTROL, both, to ATT HOLD.

Okay. MODE CONTROL, both, to ATT HOLD.

Okay. Two steps below that, add back in TTCA COMMANDER THROTTLE MIN DPS, and add in DPS.

Wait a minute.

Stand by 1.

TTC—Yes. Seems like you should be in JETS, since this is going to be—is this going to be RCS or a DPS burn?

Okay. This will be JETS for RCS and THROTTLE for DPS.

What I don't understand is, what is this MCC likely to be? I thought it was going to be an RCS.

Well, we—We expect that, but we're remaining flexible.

(Laughter) Okay. Okay. I'll put in TTCA THROTTLE MIN for DPS, JETS for RCS.

That's correct. Okay. That's all on page 33. Go to page 34.

Okay. Beneath everything on that page, add in the following. Return to “Entry,—LM PREP” check—return to “Entry, LM PREP” checklist —

Hold on, Vance; I don't understand. We want to delete everything on page 34?

No, that's not correct, Fred. What we wait to do is leave everything the way it is on 34, and add this one comment I'm giving you at the—at the bottom of it.

Oh, okay. Okay. I misunderstood. Okay. Go ahead with your added comment.

Return to “Entry LM PREP checklist.”

Add “EI” —

… turn to—return to “Entry, LM checklist?”

That's affirm. At EI minus 5 hours.

Okay. At EI minus 5 hours. Let me take a look and see how that flows, now.

Okay. And also you have a —

Okay. That would be the LM—the LM preentry procedure. Yes. Okay.

That's correct, and, also on that page, you—from our last correct—or addition exercise, you have a section called “Reestablish PTC.” We'd like to scratch all of that, of course.

Roger.

Stand by 1. Fred, we're polling the room for comments here, any last minute thoughts from people. We'll be right back with you.

Aquarius, Houston.

Okay, Go ahead.

Okay, Fred. Just two changes, comments to what we just gave you. The first is near the front at EI—in the section under “EI minus 2-1/2 hours,” power removal from CM LM umbilical." We'll let you turn to that.

Okay, I'm there at “EI minus 2-1/2 hours, power removal CM LM umbilical.”

Okay. Under LM, we have a step, BAT 2, LOW VOLTAGE, OFF/RESET, than ON. Next we have a step BAT 2, HI VOLTAGE. OFF/RESET, then ON. We request that you wait in between these two steps for us to give you a GO. In other words, we'd like to look and see that all the relays closed and all that sort of thing before you throw BAT 2, HI VOLTAGE, to OFF/RESET, and ON.

Okay, After BAT 2, LOW VOLTAGE, OFF/RESET, I'll—then ON, I'll wait for a MSFN GO before proceeding.

Right-o. Okay. Next, at—Under the section of “EI minus 1 hour and 45 minutes”—No, change that. Correction, “EI minus 1 hour, 35 minutes,” refer to the ECS section, and we have a change.

All right. Go ahead, Vance.

Okay, Jim's right. We should cross out all this stuff with a couple of exceptions. FORWARD DUMP valve, closed, the first step, should remain. All other steps should be scratched, except for the last one, which is OVERHEAD DUMP valve, closed. That leaves two steps.

Okay. Under ECS, we delete all except the first step, FORWARD DUMP valve, close, and step 10, which is OVERHEAD DUMP valve, closed, and leave in verify transfer list.

That's affirm. Leave in what follows, which is verify transfer list and IVT and all that.

IVT, of course, meaning CDR transferring to the CM.

We wouldn't forget it.

Okay, Fred-o. That's—That's the changes. Not quite as extensive as the CSM had, but still pretty long. Any comments or questions to the house here?

Okay. Which one?

Okay. Stand by 1.

Is it the one Jack wrote them all in? The big long readout? He also wrote something in the G&N book.

It's in the big, long one he wrote out at about EI minus 02:30. EMS entry check.

Okay. He's coming back down with it.

Meanwhile, Fred, I've got two for you on the LM PREP checklist.

Okay. Jack's here now. I'll hand it to him.

Okay, Houston; Aquarius.

Hello, Aquarius. I've got a couple of changes for you on your CSM checklist.

Okay. Stand by 1.

Okay. Go ahead.

Okay, Jack. The time line between EI minus 02:30 and 1 hour is real crowded, so you're really going to have to hustle, and we've decided to delete the EMS entry check at minus 02:30. That'll give you a little more time in there. What we've decided to do with it is wait until after EI minus 1, just before you initialize the EMS. If you have time, and only if you have time, do the EMS entry check. Otherwise, forget it and go right on into EMS initialization. You understand?

Okay. You're going to delete between 2 hours and 30 minutes and 02:15 there, and you're going to add it, if there is time, only if there is time, at EI minus 1 hour where the EMS initialization occurs .

That's right. You got it correctly. Okay, Jack. One other item. Just before EI minus 2 hours and 15 minutes, we need an E-memory dump VERB 74 ENTER. Over.

Okay. Stand by 1, would you, please?

Okay. Right before 2 hours and 15 minutes, I assume that's before MSFN gives their P27 update, I do a VERB 74. Right?

That's affirmative, Jack.

How much sleep did you get, Jack?

Oh, I guess—Stand by. I guess maybe 2 or 3 hours. It was awful cold, and it wasn't very good sleep.

Roger. You plan to try to get any more?

What GET do you have?

We got 132:37.
