04 12 24 02
Jack Lousma (CAPCOM): Okay, Jim. We got it. The Earth went by at a minus 8 degrees. On a basis of the data —
04 12 24 08
Jim Lovell (CDR): That's right.
04 12 24 09
Jack Lousma (CAPCOM): On the basis of the data we have so far, your entry angle is 5.99. The block data we gave you on the pad for a no-COMM midcourse-7 last night is no longer valid because we made this midcourse.
04 12 24 38
Jim Lovell (CDR): Okay. Understand, the no-COMM pad is no longer valid because of the midcourse. Entry angle based on the last 2 hours' tracking is 5.99, and I take it you're going to keep tracking for some time now to see whether we need another midcourse or not.
04 12 24 55
Jack Lousma (CAPCOM): That's affirmative.
04 12 25 05
Jim Lovell (CDR): Are you planning any no-COMM midcourse at 134 and change anyway right now, or are you going to wait?
04 12 25 14
Jack Lousma (CAPCOM): We're discussing that now, Jim, and it looks like we're going to wait on the tracking. For the time being, since you're in the corridor, why, there's no need to pass it up. But we're going to keep looking at the tracking, and we'll probably come up with one.
04 12 25 34
Jim Lovell (CDR): All right. I'm not too sure what the venting is going to do to us so—when this SHe tank ruptures, what it's going to do for us.
04 12 25 47
Jack Lousma (CAPCOM): Roger. We don't presently expect the SHe tank to have any effect on your trajectory, and the pressure's up to 1921 now.
04 12 25 59
Jim Lovell (CDR): Hey, it's going a lot better than we ever expected. What a way to get a data point.
04 12 26 35
Jim Lovell (CDR): And, Jack, just think. You thought you were going to sleep through all your watches.
04 12 26 41
Jack Lousma (CAPCOM): Say again, Jim.
04 12 26 48
Jim Lovell (CDR): I said, you thought you were going to sleep through all you watches.
04 12 26 58
Jack Lousma (CAPCOM): Well, you keep waking me up.
04 12 27 04
Jim Lovell (CDR): Sorry about that.
04 12 54 31
Jack Lousma (CAPCOM): Aquarius, Houston. You notice anything?
04 12 54 37
Jim Lovell (CDR): Yes, Jack. I was just about ready to call you. Underneath quad 4, I noticed a lot of sparklies going out.
04 12 54 50
Jack Lousma (CAPCOM): Can you hear or feel anything?
04 12 54 54
Jim Lovell (CDR): No, I sure can't, but I think it changed our—it changed our PTC. Let me check and see what the drift is.
04 12 55 09
Jack Lousma (CAPCOM): Okay. She's going down through 600 now.
04 12 55 18
Jim Lovell (CDR): I think we're probably going to have to reestablish PTC. Yes, we got pretty fast yaw drifting, Jack.
04 12 55 57
Jim Lovell (CDR): Houston, Aquarius. What are your plans?
04 12 56 01
Jack Lousma (CAPCOM): We're thinking about them right now. Did you say it yawed some?
04 12 56 08
Jim Lovell (CDR): Yes, I was in a right yaw and now I'm in a left yaw; at a much faster rate than the one we put in PTC.
04 12 56 28
Jack Lousma (CAPCOM): Okay, Jim. We're talking it over. Stand by.
04 12 57 20
Jim Lovell (CDR): What's the SHe tank down to now, Jack?
04 12 57 24
Jack Lousma (CAPCOM): Okay, Jim. It's going through 125 pounds now. And we understood you to say —
04 12 57 30
Jim Lovell (CDR): Okay.
04 12 57 31
Jack Lousma (CAPCOM): — that it reversed your yaw. Is that affirmative?
04 12 57 37
Jim Lovell (CDR): Sure did, Jack. It reversed my yaw completely and put in a little pitch, I think.
04 12 57 53
Jim Lovell (CDR): But more than anything, it reversed my yaw.
04 12 57 56
Jack Lousma (CAPCOM): Roger. Have you effectively established PTC in the opposite direction then?
04 12 58 04
Jim Lovell (CDR): Well, you could say that. I'm not too sure just what kind of pitch or roll I've got, coupled with the yaw. I just saw the Earth go by the LMP's window here, not too long ago at a rather faster rate than we had going the other direction.

04 12 58 38
Jim Lovell (CDR): Perhaps you can tell how fast I'm having to shift OMNIs.
04 12 58 42
Jack Lousma (CAPCOM): Yes, we can tell the COMM cycling back and forth.
04 12 58 52
Jim Lovell (CDR): Is that what they call a nonpropulsive vent?
04 12 58 56
Jack Lousma (CAPCOM): Right. I'd hate to see a propulsive one.
04 12 59 01
Jim Lovell (CDR): You and me both.
04 12 59 04
Jack Lousma (CAPCOM): It's going through 50 pounds now. So, are you seeing fewer sparklies?
04 12 59 12
Jim Lovell (CDR): Yes. Much fewer. Not any at all, now. I'm not sure whether that vent gave me reverse yaw and roll—left roll—that's—if that's what it gave me.
04 12 59 34
Jack Lousma (CAPCOM): You say you think it might have given you some left roll as opposed to opposite yaw.
04 12 59 45
Jim Lovell (CDR): I'm sure it gave me the yaw, Jack, but I'm not too sure …
04 12 59 50
Jack Lousma (CAPCOM): Okay. We'd kind of like to watch it, see what happens for a little while before we make a recommendation. However, we'll need some inputs from you on that.
04 13 00 02
Jim Lovell (CDR): Well, we're in no trouble up here as far as—as far as the yaw goes. Everything's fine. It's faster than we had set up before. We just wanted to get into proper thermal constraint, and it's going to take me 15 minutes to get the thrusters up anyway.
04 13 00 58
Jack Lousma (CAPCOM): Okay, Skipper. We don't see any thermal problems as a result of this change. If we see some communications problems, we may have to do something different, but so far, so good. And we'd kind of like to hear from you on LPD numbers, if you get anything going by the window.
04 13 01 28
Jim Lovell (CDR): Okay. Will do.
04 13 02 03
Jack Swigert (CMP): Okay, Jack. The Earth just went through at an LPD of 26 degrees.
04 13 02 09
Jack Lousma (CAPCOM): Okay. The Earth went through at 26 degrees going the opposite direction this time—left to right. Is that right?
04 13 02 17
Jack Swigert (CMP): From left to right. That's affirmative.
04 13 02 32
Jack Lousma (CAPCOM): Of course, the only other thing that we'd be concerned about is what change in your velocity this might have had and what DELTA-V it imparted, and we'll have to look at that for a while before we are able to determine it. And, if there is no significant change, why, we prefer just to leave it the way it is.
