Ken Mattingly (CAPCOM): Apollo 8, Houston.
05 22 17 35
Frank Borman (CDR): Go ahead, Houston.
05 22 17 37
Ken Mattingly (CAPCOM): Okay. We have checked into your drogue time, and the number of 08:16 on your entry PAD is correct. We'll be giving you an updated entry PAD on the scheduled time of 143:30. At the same time, we'll be giving you an update of your state vectors for the LM and CSM. The midcourse correction number 7 was less than seven-tenths foot per second, and we will not execute it. You have a P52 scheduled at 143:30 which is not required. It's your option. However, if you decide to delete the P52, the CMC self-check and DSKY condition light test are still requirements. Over.
05 22 18 32
Frank Borman (CDR): What do you mean, they are still requirements? We weren't planning to do the CMC self-test.
05 22 20 53
Frank Borman (CDR): On that DSKY check . ..
05 22 21 07
Ken Mattingly (CAPCOM): Apollo 8, Houston. That's my mistake on CMC self-check and DSKY condition light. That's an optional test. Over.
05 22 21 16
Frank Borman (CDR): That's what we thought, Ken. Gosh, if that's been working perfectly for 6 days, I don't see any reason to test it.
05 22 21 24
Ken Mattingly (CAPCOM): I agree.
05 22 21 26
Frank Borman (CDR): Thank you.
05 22 21 36
Jim Lovell (CMP): Morning, Ken. How's Houston this morning?
05 22 21 39
Ken Mattingly (CAPCOM): Just fine. Nice and balmy.
05 22 21 44
Jim Lovell (CMP): Good.
05 22 51 28
Bill Anders (LMP): Houston, Apollo 8. Over.
05 22 51 31
Ken Mattingly (CAPCOM): Go ahead, Apollo 8.
05 22 51 45
Ken Mattingly (CAPCOM): Apollo 8, go ahead.
05 22 51 49
Bill Anders (LMP): I am just—It is my understanding that we are to bring up the secondary loop at 1 hour prior to SEP, isn't that right?
05 22 51 54
Ken Mattingly (CAPCOM): That is affirmative, about page Echo 9.
05 22 52 10
Bill Anders (LMP): Okay.
05 22 52 16
Ken Mattingly (CAPCOM): And Bill, … suggested if we have the water boiler going on the primary loop, that you—you might wait about 5 minutes or so before you initiate the secondary loop.
05 22 52 38
Bill Anders (LMP): Wait 5 minutes from what? From the time the primary loop starts or from 1 hour?
05 22 52 43
Ken Mattingly (CAPCOM): From the time the primary loop starts; this will give you a check to see if it had a chance to dry out or not.
05 22 53 04
Bill Anders (LMP): Oh, I am with you. Okay.
05 22 53 09
Ken Mattingly (CAPCOM): And for your information, we already have a VHF downlink. It's poor quality, but we do have contact.
05 22 53 22
Bill Anders (LMP): Okay. We haven't turned anything over to VHF yet.
05 22 53 25
Ken Mattingly (CAPCOM): Okay.
05 22 53 27
Bill Anders (LMP): We tried to call you on the VHF though, Ken.
05 22 53 30
Ken Mattingly (CAPCOM): Roger. I say, the quality is pretty poor; they may not be able to understand you.
05 22 53 36
Bill Anders (LMP): Roger.
05 22 56 59
Frank Borman (CDR): Houston, Apollo 8. Over.
05 22 57 01
Ken Mattingly (CAPCOM): Go ahead, Apollo 8.
05 22 57 14
Ken Mattingly (CAPCOM): Apollo 8, Houston. Go ahead.
05 22 57 17
Bill Anders (LMP): Ken, we got two things going here which make this suit heat exchanger flow a little different. One of them is we are not doing a coldsoak, and the other one is we are powering down the secondary loop prior to SEP. And I wonder if it is a good idea to have the suit heat exchanger only on a secondary loop in that case. And plus the fact that we haven't got any cabin heat exchanger.
05 22 57 45
Ken Mattingly (CAPCOM): I don't think that was the intent, Bill. What they had in mind, we have the suit heat exchanger on both loops; and if they got too cold, you could use the panel switching to shut down the primary loop through the heat exchanger. But in any event, you would always have something going to the suit heat exchanger. I recognize that we are going to be shutting down the secondary heat exchanger pre-SEP and then turning it back on prior to entry, but the idea was to have both primary and secondary loops on the suit heat exchanger simultaneously.
05 22 58 24
Bill Anders (LMP): Yes, my checklist doesn't reflect that. I think that's a good idea because we are a little suspect of our cabin fans and don't plan to use them.
05 22 58 31
Ken Mattingly (CAPCOM): Roger.
05 23 01 54
Bill Anders (LMP): Houston, Apollo 8. Over.
05 23 01 58
Ken Mattingly (CAPCOM): Go ahead, 8.
05 23 02 08
Ken Mattingly (CAPCOM): Apollo 8, Apollo 8. Go ahead.
05 23 02 12
Bill Anders (LMP): Roger. What's Rod's estimate of our postseparation main bus voltage?
05 23 12 41
Ken Mattingly (CAPCOM): Apollo 8, Houston. We will be making a handover from, Carnarvon to Honeysuckle at 15.
05 23 12 50
Frank Borman (CDR): Roger.

Ken Mattingly (CAPCOM): Apollo 8, go ahead.
05 23 16 24
Bill Anders (LMP): I am still a little bit confused on that- on this activating the secondary loop. You indicated inactivating it at 1 hour or 5 minutes after the primary evaporator comes on the line. My checklist shows that the primary evaporator probably won't come on the line until we bypass the radiators. Have you got something else in mind I don't know about?
05 23 16 56
Ken Mattingly (CAPCOM): Okay, Bill. We passed up an update some time back on page E-9 step 38 right at the beginning, and you have got a final GET drift check. And between there and the step 39 where it says terminate CM RCS preheat, that was the place we wanted to activate the primary loop by putting the glycol evaporator water switch to AUTO and the glycol evaporator steam pressure to AUTO.
05 23 17 41
Bill Anders (LMP): Roger. I don't expect it to boil, though. Do you?
05 23 17 45
Ken Mattingly (CAPCOM): Okay, Bill. We are hoping that it will there. It looks like we will have had a stable attitude for sometime, and we anticipate that it will be warm enough to make it boil. That is the reason it's suggested if it is boiling, that you wait. If it isn't, go ahead and turn on the secondary loop.
05 23 18 04
Bill Anders (LMP): Okay. Well, that's where I was confused. I am waking up. Thank you.
05 23 19 08
Ken Mattingly (CAPCOM): Yes, sir.
05 23 20 06
Ken Mattingly (CAPCOM): Apollo 8, Houston.
05 23 20 09
Bill Anders (LMP): Go ahead, Houston.
05 23 20 11
Ken Mattingly (CAPCOM): Okay, Apollo 8. We would like to update your LM state vector, CSM state vector, and target point. If it is convenient now, why, we will go ahead and do that if you will go to P00 and ACCEPT.
05 23 20 27
Bill Anders (LMP): Roger. P00 and ACCEPT.
05 23 29 20
Ken Mattingly (CAPCOM): Apollo 8, Houston.
05 23 29 22
Frank Borman (CDR): Go ahead, Houston. Apollo 8.
05 23 29 25
Ken Mattingly (CAPCOM): Okay. The loads are in and verified, and the computer is yours.
05 23 29 29
Bill Anders (LMP): Okay.
05 23 29 30
Ken Mattingly (CAPCOM): You can take it back to BLOCK, and for Bill's information, latest guess from the main bus post-SEP voltage to 27.5
05 23 29 41
Bill Anders (LMP): Guess! You mean the EECOM's are guessing?
05 23 29 57
Bill Anders (LMP): At least, they are honest for a change.
05 23 30 02
Ken Mattingly (CAPCOM): That is more than you can say for the computers.
05 23 30 06
Bill Anders (LMP): Or the crew.

Ken Mattingly (CAPCOM): Apollo 8, Houston.
05 23 37 00
Ken Mattingly (CAPCOM): Apollo 8, Houston.
05 23 37 03
Bill Anders (LMP): Go ahead, Houston. Apollo 8.
05 23 37 05
Ken Mattingly (CAPCOM): Okay, 8. We have an entry PAD for you.
05 23 37 10
Bill Anders (LMP): Good. Just a minute.
05 23 37 33
Bill Anders (LMP): Ready to copy, Houston.
05 23 37 38
Ken Mattingly (CAPCOM): Okay. This will be the mid-Pacific, 357 152 359 146:29:00 268, plus 0813, minus 16503 065 36221 645 12122 36301 146:46:14 0028. The next block is November Alfa: D₀ 400 02 12 0025 0334 08 14 16 0590 312; Zeta Persei, up 165, right 34, up. Use nonexit EMS pattern, GDC align; primary star Sirius, secondary Rigel, roll 308, pitch 209, yaw 357; this entry will not involve P65. Over.
05 23 40 25
Jim Lovell (CMP): Houston, Apollo 8. Entry PAD as follows: mid-Pacific, 357 152 359 146:29:30 268 plus 0813 minus 16503 065 36221 645 12122 36301 146:46:14 0028, next block not applicable, 400 0212 0025 0334 0814 16059 312, Zeta Persei, up 165, right 35 up, use nonexit EMS pattern, backup alignment; Sirius, Rigel, roll 308, pitch 209, yaw 357, and we won't need P65.
05 23 41 37
Ken Mattingly (CAPCOM): Okay, Apollo 8. I would like to verify sextant star shaft 0590, and the boresight star.
05 23 41 49
Jim Lovell (CMP): Roger.
05 23 41 50
Ken Mattingly (CAPCOM): The last one is right 34. Over.
05 23 41 56
Jim Lovell (CMP): Roger. Boresight star is right 34. And I have the sextant shaft; that's 0590.
05 23 42 03
Ken Mattingly (CAPCOM): That's correct, Apollo 8.
05 23 59 37
Ken Mattingly (CAPCOM): Apollo 8, Houston.
05 23 59 50
Ken Mattingly (CAPCOM): Apollo 8, Apollo 8, Houston.
05 23 59 56
Jim Lovell (CMP): Go ahead, Houston.
05 23 59 58
Ken Mattingly (CAPCOM): Okay, Apollo 8. Can you tell us if you've done anything with your potable water? We've noticed our readout has gone from 100 percent down to 56 in the last couple of minutes.
06 00 00 17
Jim Lovell (CMP): We're reading about 50 percent right now.
06 00 00 22
Ken Mattingly (CAPCOM): Roger. That correlates with what we see. Have you done anything to change configuration? Over.
06 00 00 44
Jim Lovell (CMP): Yes, we noticed the venting here, too, Houston.
06 00 01 10
Ken Mattingly (CAPCOM): Jim, did you mean you could visually see it?
06 00 01 14
Jim Lovell (CMP): Yes, we're—oh, stand by, Ken. Bill just dumped urine, so that might have been urine we were seeing.
06 00 01 45
Jim Lovell (CMP): Bill just shut the potable inlet, Ken.
06 00 01 48
Ken Mattingly (CAPCOM): Okay. Thank you.
06 00 04 44
Jim Lovell (CMP): Houston, Apollo 8.
06 00 04 47
Ken Mattingly (CAPCOM): Go ahead, 8.
06 00 04 58
Ken Mattingly (CAPCOM): Apollo 8, Apollo 8, go ahead.
06 00 05 01
Jim Lovell (CMP): Roger, Houston. We're still showing about 52 percent, and we had our switch on waste so we don't know whether it dropped from a higher value or not. Has yours been stabilized now?
06 00 05 15
Ken Mattingly (CAPCOM): That's affirmative; ours has stabilized now. It was reading full just a few minutes ago.
06 00 05 25
Jim Lovell (CMP): Roger. I don't think—we can't account for any sudden drop in water.
06 00 05 31
Ken Mattingly (CAPCOM): Okay. We looked in the malfunction procedures, and number 28 doesn't reveal anything very startling.
06 00 05 42
Jim Lovell (CMP): Bill is looking there now.
06 00 08 53
Bill Anders (LMP): Houston, Apollo 8. Over.
06 00 08 57
Ken Mattingly (CAPCOM): Go ahead, 8.
06 00 09 00
Bill Anders (LMP): Okay. I'm looking at malfunction 28, and it takes you to box 6, but I don't really think that's the problem because the waste tank quantity hasn't changed any. Over.
06 00 09 11
Ken Mattingly (CAPCOM): Okay. I concur. We're watching the same thing.
06 00 09 15
Bill Anders (LMP): Look, we don't care about the potable tank, but we do about the waste tank, so just in case there is a problem somewhere, I'm going to shut the potable tank off and leave the waste tank inlet valve open. How does that sound to you?
06 00 09 29
Ken Mattingly (CAPCOM): Stand by. Okay, 8. We concur.
06 00 09 37
Bill Anders (LMP): If I see any water floating around, I'll give you another call.

Ken Mattingly (CAPCOM): Okay. Two fast items: number one, it has been suggested that since Marezine takes some time to take effect, you might consider whether you would be interested in taking some now. And I have an entry PAD which has some very small updates to go on it if you would like to copy that.
06 01 11 22
Frank Borman (CDR): Okay. Stand by. Let me get out the entry PAD.
