Spacelog Apollo 13

All right, sir. Okay, Jack, and they'd like us to stand by just a second.

Jack, would you get the BATTERY CHARGER, OFF, please. And we'll send you —

Okay.

— the rest of that procedure later.

You mean there's more? Okay, in work. BATTERY CHARGER is going OFF.

Right.

Okay, Vance. Okay—I don't think you've given me the backout procedure, have you, for the battery chargers?

That's negative. Wait. All we want to do, Jack, is say BATTERY CHARGE OFF at the moment. We'll complete that procedure as soon as you are through with Ken completely.

Okay, Vance. The BATTERY CHARGER's OFF, and I'm ready to continue with Ken.

Okay, Jack. And we'll get the backout to you after that.

Okay, Jack. It looks like we've closed up the loose ends here. Amazingly enough, out of all that stuff, it looks like we only generated one question on the floor, and we'll research that one. We'll even let you guess what it might have been. If you have any questions, after you mull it over, why, we're always available. Just ask us what you're thinking about.

Okay. That's what we're going to do. We're going to wait until the LM people get theirs, and then we're going to discuss it and coordinate things here, and make sure that—that we don't have any interface problems. And, if we have any more questions, we'll be coming back at you.

Okay. We did run the thing integrated, so we think we've got all the little surprises ironed out for you.

I hope so because tomorrow is examination time.

Roger.

Ken, this is Jim.

Yes, sir.

Appreciate the work you've done, and Jack says that it's going to be hard to beat his record about saving SM RCS fuel all the way there and back.

I can't do much about that.

Some people will do anything to set a record.

Hey, Jim, you even did good on service module fuel this time.

Yes. We're coming back with a full load almost of both RCS and SPS, that's—That's pretty much of a record.

Okay. Did you want to put Fred-o on, or somebody to copy the LM—the LM side of the house.

Hey, Jack. Don't wake him up yet. Stand by 1.

He's—He's awake.

Hey, Jack. We'll give you this battery charging backout procedure, and then Deke says you ought to get some sleep. You're going to need it tomorrow.

Okay. I'm ready to copy the backout procedure.

Okay. Panel 3: BATTERY CHARGE, OFF—you've already done that, Jack—next AC INVERTER, INVERTER 2 OFF: Panel 5: MAIN BUS TIE BAT B/C to BAT B/C. Huh? Yes, it's up—the up position. Panel 250: circuit breaker, BAT A POWER ENTRY/ POSTLANDING to open; circuit breaker, BAT B POWER ENTRY/POSTLANDING, open, Panel 5: CB BATTERY CHARGER BAT B CHARGE, open. Okay. I'll let you read that back, Jack.

Okay. BAT CHARGE, OFF; AC INVERTER 2 to OFF; MAIN BUS TIE, BAT B/C to on, up. Panel 250: BAT A, POWER ENTRY AND POSTLANDING, open; CB, BAT B, POWER ENTRY and POSTLANDING, open. Panel 5: CB BAT CHARGER, BAT B CHARGED, open.

Okay. That's correct. Now, that gets you back to the place where you can back out of the—the big battery charging procedure, which you have. And I—I think you have the backout procedure for that, but I'd like to check with you.

Okay. Stand by here.

Okay, Jack. Do you have that backout procedure in your hand there?

Yes, I do, Vance.

Okay. Just to verify. It starts out panel 3, BATTERY CHARGE switch, OFF; AC INVERTER 2, OFF; panel 5, MAIN BUS TIE, BAT A/C, on, up, et cetera.

Roger. Continues CB BAT A, POWER ENTRY/ POSTLANDING, open; INVERTER POWER 2, MAIN B, open; and then you reverse the steps that you had for entering the procedure.

Yes, that's fine. Okay. And we have one other comment regarding the systems checklist, and stand by 1, and that'll—that'll wrap it up for us. Oh, a new item came in, Jack. We need to switch to ascent water, and I have a three-step procedure for you, if you're ready to copy.

Okay. Jim will copy that.

Okay. DESCENT WATER valve, CLOSE. ASCENT WATER valve to CLOSE, and WATER TANK SELECT valve to ASCENT.

Okay, Vance. DESCENT WATER valve, closed; ASCENT WATER valve, closed; and WATER SELECT TANK to ASCENT. Is that correct?

WATER TANK SELECT valve, ASCENT. That's correct, Jim.

And we'll proceed with that right now, and how about still drinking descent water?

Jim, we understand that you should be able to continue drinking, it.

Okay. We switched to ascent water, but we'll probably have to have the descent water valve back open up again to drink water.

That's affirm. That's the one thing you'll have to do is, whenever you want to drink out of the descent tank, is open the descent valve—the DESCENT WATER valve momentarily.

Okay. And we are now on ascent water.

Okay; okay. And I need Jack back again, please.

Okay, Vance. I'm here, and you have something in the systems checklist.

That's right. Refer to S/2-6. This—Really what we're talking about, Jack, is the hatch integrity check decal. And I think it'll be easiest, if you'll open to S/2-6 and I explain it to you.

Okay, Vance. I'm ready to copy.

That's affirm. And the two lines below “30 seconds.” And actually the part of the fourth line there, which is “8-1/2 minutes.”

Stand by. Can you read okay?

Yes. I hear you now.

Okay. Delete the two lines below that, or the two-and-a-half lines below that, also.

That's affirm. And now, we have an addition to put in place of what we deleted. Stand by 1; the COMM's bad. How do you read?

Roger. Loud and clear.

Okay. We want you to vent—tunnel vent until, and add the following, “Until LM/CM DELTA-P is equal to 3.0 psid.”

Okay. “Until LM/CM DELTA-P equals 3.0.”

Okay. And that means that you'll have a pressure of 1.5 to 2 in the tunnel, absolute. That's —

Okay.

That's a note.

Jack, that's what we want to end up with ultimately is 1-1/2 to 2 there in that tunnel and depending on the gage reading, but that should be about 3.

Okay, Deke.

Okay, then, Jack. Continuing on, everything's okay until you get down to—on the next page, you get through “Verify O₂ FLOW INDICATOR no increase.” We would like to delete everything below that, until the last step, which is TUNNEL LIGHTS, OFF. So starting with “Before undocking only,” delete all lines through “TUNNEL VENT VALVE to TUNNEL VENT.”

Okay. Delete the section that says “Before un-docking only” down to where it says “TUNNEL VENT VALVE to TUNNEL VENT.”

Yes, through that.

Well, through that. Leave “TUNNEL LIGHTS OFF” is the only step remaining.

Roger. And just—That's a verify.

Okay. Got that.

Okay. Really what this does for you, then, is it gives you a pressure—a tunnel pressure integrity—or a hatch pressure integary—integrity check with a DELTA-P of 3 psi between the tunnel and the cabin. And then you never go on to the steps of venting that on out. You just leave it in there for the time that you separate from the LM. And that gives you a shotgun DELTA-V effect.

Okay. Copy that.

Okay. I think that's all, but we're polling the house here to see if there's another comment for you. Stand by.

Aquarius, Houston.

Go ahead, Vance.

Jack, that's it. Unless you have any more questions, why, everyone is hoping you'll hit the sack and get some rest.

Okay. You want that battery backout procedure now to take that—to complete the remaining steps?

That's affirm, Jack. We request that you go ahead and finish out the backout completely until you get to square 1. Over.

Okay.

Houston, Aquarius.

Go ahead, Jim.

Do you have any more updates for us?

We've still got a LM update, but we strongly recommend that you and Jack work as hard as you can sleeping for about the next 5 hours. Fred can handle it.

Okay. That's what we'll do. We'll put Fred on watch here, and Jack and I will take it easy, and if Fred copies the LM update, well, then we'll all start from fresh in the morning.

Aquarius, Houston. Over.

All right, go ahead, Vance.

Okay, Fred. Two—three things. First thing is we need a docking angle check as soon as you can conveniently get it. Second point, you're free to drink all the descent stage water you want, if that wasn't clear before. And the third point, if you have a piece of paper, stand by to get writer's cramps. We have something to give you here.

Okay. You want the—again a look at the docking tunnel index?

Why don't you go ahead and look at that —

… —

Look at that first, yes.

Okay.

Okay. Jim says the docking tunnel index is a plus 2.1 degrees.

Okay. Plus 2.1 degrees, docking tunnel index.

Okay. He corrects himself. He says make that sign a minus. Minus 2.1 degrees.

Okay. We just changed, plus to minus.

Okay. And your second item was, we can drink all of that descent waster that's left—looks like about 5 percent, and I'll get a book here and be ready to start writing.

Okay. Get—This won't be as long as—as the one T. K. read up, but you'll need several pages, probably.

Okay. I've got lots of pages here of Ken's photo log set to go.
