Spacelog Apollo 13

Okay. You want me to delete “For 30 seconds.”

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.

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.
