Roger. At 96 hours EEP, battery A has 38.95 amp-hours; battery B has 36.35 amp-hours; battery C has 38.46 amp-hours. Your total, 113.76 amp-hours. At 97 plus 50, battery A will be fully charged and will have 40 amp-hours, and you can terminate charge at that time. Over.

We gave you back VERB 64. I wonder if you could have Guidance figure out a corridor correction at 114 hours for us with a minus 648 cabin.
-
Jerry Carr (CAPCOM)
-
Okay, Jim. We copy, and now we see we've got VERB 64 back. We'll be back with you in a minute.

Jerry Carr (CAPCOM)

Okay. Based on your vector, the CMC vector, the ground computes 15.3 feet per second on the midcourse, VEI of 36221, a gamma EI of minus 6.51 so it looks like your P37 program is pretty good. Applying your P37 solution to our MSFN vector, however, we get a gamma EI of minus 10.32. We expect these two solutions to converge with a little more tracking and after you get some earth horizon sightings. Over.

Jim Lovell (CMP)

Roger. How valuable do you think that the lunar we did just after TPIR as compared to your MSFN tracking? Go ahead, Houston.
-
Jim Lovell (CMP)
-
Roger. I was getting curious of the value of onboard tracking in the P23 course close to the moon, in regards to the MSFN tracking that close to the moon. I think there might be a trail-off for onboard navigation, and I think it might be a little bit better than MSFN tracking.
-
Jerry Carr (CAPCOM)
-
Roger. I guess the experts would say that the MSFN data was probably best based or the number of sightings that you have taken. However, that's going to be the subject of quite a bit of evaluation, I think, after the mission. Over.

Jerry Carr (CAPCOM)

Roger, Jim. Be advised that we are beginning to read you very weak, and with a rather loud background noise.

Roger, Jim. Christmas morning around your house was kinda quiet, says Marilyn. She said that they are all thankful the mission has gone so great. They missed having you around the tree this morning, but they wanted to reassure you that your presents are waiting, and the roast beef and Yorkshire pudding will be on the table when you get home.

Jerry Carr (CAPCOM)
-
Yeah, man. Is Frank listening?

Okay. Have Frank give me a holler when he is ready. I've got a message for him, too.

Jerry Carr (CAPCOM)

Real good, Jim. Santa Claus struck last night before I came in here on the shift, and I guess we will finish off the unwrapping this morning when I get back.

Jerry Carr (CAPCOM)

Hi, Frank. Christmas morning has come at the Borman house. And the boys and Susan and your Mom and Dad all send their love. They say for you to stay in there and pitch. Over.

I just worked out an answer to move my landing longitude 6 degrees east. I just want to compare with what they've got based on the same burn time of 114 hours, based on the bias impact longitude determined from the P37 which is wrong. I've indicated that I need 600 foot per second DELTA-VC burn plus, and my DELTA-VX changes from a minus 11.6 feet per second. I'd like to have them verify that if I could.
-
Jerry Carr (CAPCOM)
-
The voice isn't too great right now, and the Guidance troops didn't get all of that. How about waiting about 2 or 3 minutes? We'll swap OMNI antennas, and then we should get good voice transmission from you and then repeat it. Would you, please?
-
Jerry Carr (CAPCOM)
-
Roger. We're reading you much better now. Jim can go ahead with his transmission to the guidance troops. They have one question before he starts. They would like to know what his GERU was at TIG, 114 hours. Over.
-
Jim Lovell (CMP)
-
Okay, Houston. Based on the P37 with minus MA solution, I got an impact longitude of minus 160.95. I biased it to get an impact latitude—longitude of 163.75. I wanted to change my impact point 30 degrees to the east, and I tried to determine what my P30 burn parameters would be to do this, and I got a DELTA-VX burn of minus 11.6 and a DELTA-VC of plus 600, DELTA-VY of zero. Now that changed my previous DELTA-VX burn from minus 50.2. I just want to know whether that meets with their approval.

Roger. At 100 hours 30 minutes, change star number 02 from one set to two set. Over.
-
Jerry Carr (CAPCOM)
-
Roger. Also, set number 2, set number 2, change star number 11 to star number 7. Over.
-
Jerry Carr (CAPCOM)
-
Roger. Then after star set number 3, initiate PTC again; pitch 10, yaw 45. Over.
-
Frank Borman (CDR)
-
Pitch 10, yaw 45.

That's affirmative. The folks here are evaluating the thermal situation. Looks like you will be out of PTC rather at an extended period of time. That's the reason we have you initiating PTC again there around 101 as soon as you finish those three star sightings. We are still working on the—about the next 10 hours after 100 hours. We are looking at the thermal situation, and the star sighting situation, and we will be giving you more updates later on. Over.
-
Frank Borman (CDR)
-
Roger. We don't have a thermal problem at all now, do we? All our indications here are normal in here.
-
Jerry Carr (CAPCOM)
-
Roger. Everything looks okay. I think they're just kinda trying to look down the track aways.
