Okay. Coming up on the 88-hour mark. I'll give you a 2-second delay. Stand by to mark.

Pretty good, Jack. Say, you might have the people look at our DPS burn card to see what changes have to be made on it for the burn.
-
Jack Lousma (CAPCOM)
-
Heard you say look at the DPS burn; you'll have to say what about it again, please.
-
Jim Lovell (CDR)
-
Roger, Jack. You might take a look at our DPS burn card, our checklist card that we have in the LM, and see what changes might have to be put in that checklist.
-
Jim Lovell (CDR)
-
Okay, Jack. It appears that we're going—funny diversion here, the PTC attitude in—in pitch. I'm going to do a LPD check now, but the last time the Moon went around, it was above—way away above the LPD angle and I see the Earth coming around now which is going to be pretty low. They oscillate back and forth, but each time they seem to get a little farther away from the center line. You might think of some procedure to reestablish PTC, if it's necessary.
-
Jack Lousma (CAPCOM)
-
Jim, the only way we know of getting the as good or a better PTC than you've got right now is to crank up the G & N and we—We don't want to do that. So our plan is to just take whatever we get out of this, and later on, it may turn out by the time you get to burn attitude, you'll be right where you want to be.

Jack Lousma (CAPCOM)
-
The only thing we can try to do, Jim, is to get the thing up manually and see what happens. There must be a better answer than that —
-
Jack Lousma (CAPCOM)
-
— and one course of action is to omit the midcourse and make a total midcourse, say, about 8 hours before entry. We haven't decided yet.

Jack Lousma (CAPCOM)
-
Right now we're talking about a 7-foot-per-second midcourse at 104 hours. And extrapolate that down to about 8 hours before entry. We gave you a pad for that—that's about, only 19 feet per second, so if it doesn't change too much—and we can get all kinds of DPS.

Jim Lovell (CDR)
-
Can you think of any normal venting phenomena that might occur like maybe—a hydrogen tank that's over-pressurized relieving in the window?
-
Jack Lousma (CAPCOM)
-
That is one possibility that we've though of, Jim, because—We heated up that tank, and we haven't been using any hydrogen and, therefore, it could be venting in the overboard release.
-
Jim Lovell (CDR)
-
Right. The only other thing I can think of when I look at it through the AOT is—it did appear to be coming from one spot; but that's the only difference although I can't see where it is coming from because it's beyond the curvature of the command module. But, it appears like it might be coming from more than this one spot.
-
Jack Lousma (CAPCOM)
-
Okay. Thank you. We hope that when we crank up the command module tomorrow that we'll be able to—or later on today—that we will be able to identify more closely what it's been coming from. But, the guidance guys say that they haven't been able to see the results of any venting in their data and it would take a very, very small amount to perturb their data.

Jack Lousma (CAPCOM)
-
Jim, we've had you scheduled for an eat period about an hour ago. I suppose you've taken care of that. The other thing is we're kind of interested in knowing how long you're going to be at stick there, or if you're going to go back to bed or what?
-
Jim Lovell (CDR)
-
Okay, Jack. We're—We're going to set up a regular watch and sleep period here. Fred was up for a long time, so I got up a little bit early to relieve him. Jack and Fred are now asleep, so I'm going to let them sleep as long as they can, and then we'll have an eat period and then I'll go back to bed for a bit. And we'll separate the schedule.
-
Jack Lousma (CAPCOM)
-
Okay. We're right at the point now where, according to the flight plan that we had made up for you, that you would have all finished eating and you and Jack would have the duty while Fred went to sleep. So, essentially, according to the plan we've got, you got up about 3 or 4 hours early. And—The next time that we have that as a rest period for you is at 96 hours, which is 7 hours from now, and an hour before that, say at 95 hours, all three of you would eat, and then you and Jack would hit the sack again and Fred would have the duty until 102 hours. We'd be glad to take care of this work-rest cycle for you.
-
Jim Lovell (CDR)
-
Okay. That's good. Let me—Let me wait until they get up, or at least Jack gets up. He should be getting up before Fred. And we'll try to get back on the schedule. I hate to wake everybody up right now though, if they're sleeping.
-
Jack Lousma (CAPCOM)
-
Okay. Your choice on that. As soon as Jack gets up, I'd suggest we go ahead and break up these lithium hydroxide canisters and make a couple of them. Jack could work on that. It's going to take four sets of hands, I think.
-
Jim Lovell (CDR)
-
Okay. We'll make that the project, getting the lithium hydroxide canister squared away.

Hi, Jim. We've got a flight handover in about 2 minutes, and we'll have a temporary loss of COMM. You don't need to switch antennas. Over.
