Ken Mattingly (CAPCOM): Apollo 8, Houston.
03 19 20 41
Ken Mattingly (CAPCOM): Apollo 8, Houston.
03 19 21 46
Ken Mattingly (CAPCOM): Apollo 8, Houston.
03 19 22 17
Ken Mattingly (CAPCOM): Apollo 8, Houston.
03 19 24 56
Ken Mattingly (CAPCOM): Apollo 8, Houston.
03 19 28 16
Ken Mattingly (CAPCOM): Apollo 8, Houston. Copy that you are now in PTC attitude, and we're watching your gimbal angle. We apparently do not have a downlink voice, but the data is good.
03 19 28 53
Bill Anders (LMP): Houston, Apollo 8. Over.
03 19 28 55
Ken Mattingly (CAPCOM): Loud and clear, 8.
03 19 29 07
Bill Anders (LMP): Okay. We're establishing PTC. We took one last look at the moon and on our way back.
03 19 29 13
Ken Mattingly (CAPCOM): Roger.
03 19 32 17
Ken Mattingly (CAPCOM): Apollo 8, Houston.
03 19 32 23
Bill Anders (LMP): Go ahead, Houston.
03 19 32 25
Ken Mattingly (CAPCOM): Okay. In order for us to handle the antenna switching, I guess we'd like to have the AUX tape switched to OFF, and the tape FORWARD switch OFF; and we'll be switching between OMNI's Bravo and Delta.
03 19 33 01
Bill Anders (LMP): Between what and what?
03 19 33 05
Ken Mattingly (CAPCOM): Okay. We are going to be switching between OMNI's Bravo and Delta.
03 19 33 14
Bill Anders (LMP): Okay.
03 19 33 17
Ken Mattingly (CAPCOM): Alright. And I'm gonna—you bug me when you get over 50 degrees of yaw, so I'll probably be watching that number pretty closely. We'd like to have the BIOMED switched to the right position. Okay. And for your own information: the fuel we show in the different quads I have here if you would like to copy it.
03 19 34 07
Bill Anders (LMP): Stand by.
03 19 35 50
Bill Anders (LMP): Okay. Ready to copy.
03 19 35 54
Ken Mattingly (CAPCOM): Okay. I'll give you the percentage on Alfa 60, Bravo 57, Charlie …
03 19 36 11
Bill Anders (LMP): Wait a minute. It asks for present time, and I can't plot that fast, Ken.
03 19 36 15
Ken Mattingly (CAPCOM): Okay. I'm sorry. Alfa is 60.
03 19 36 22
Bill Anders (LMP): For what time?
03 19 36 26
Ken Mattingly (CAPCOM): 91:36.
03 19 36 35
Bill Anders (LMP): Okay. Stand by.
03 19 36 44
Bill Anders (LMP): Okay. What's Bravo?
03 19 36 46
Ken Mattingly (CAPCOM): Okay. That's 57.
03 19 36 59
Bill Anders (LMP): Okay.
03 19 37 00
Ken Mattingly (CAPCOM): Charlie 62.
03 19 37 19
Bill Anders (LMP): Okay.
03 19 37 20
Ken Mattingly (CAPCOM): And Delta 57.33842.
03 19 37 33
Bill Anders (LMP): That's a coincidence. That's just what I worked out on Lovell's slide rule.
03 19 37 46
Bill Anders (LMP): How are we doing on the cryos?
03 19 37 52
Ken Mattingly (CAPCOM): Oh, you've got some pretty good numbers on that that I sent up yesterday, and you had about 160 hours. Well, I'll check that out, but you were fat on cryo. I've got some SPS DELTA-V. You've got 33:20. You fly the service module RCS through the DAP. You have 142; and through SCS, it's 121.

Bill Anders (LMP): Roger.
03 19 39 55
Ken Mattingly (CAPCOM): Apollo 8, Houston. We can't monitor on low bit rate whether you started your fuel cell purge. If you haven't, we can still go ahead and start now; and if you can, keep us posted as you go through it.
03 19 40 08
Bill Anders (LMP): Roger. You want an O₂ and an H₂ purge, Ken?
03 19 40 12
Ken Mattingly (CAPCOM): That's affirmative.
03 19 40 18
Bill Anders (LMP): You shall have it.
03 19 40 19
Ken Mattingly (CAPCOM): Thank you.
03 19 51 59
Ken Mattingly (CAPCOM): Apollo 8, Houston —
03 19 52 05
Bill Anders (LMP): Go ahead.
03 19 52 07
Ken Mattingly (CAPCOM): It looks like you may be in OMNI Alfa. Can you confirm that we're set up to switch between Bravo and Delta?
03 19 52 29
Bill Anders (LMP): You are now.
03 19 52 31
Ken Mattingly (CAPCOM): Okay. Thank you very much. And you are in the fuel cell purge?
03 19 52 39
Bill Anders (LMP): It's complete.
03 19 52 41
Ken Mattingly (CAPCOM): Okay. Understand the purge is complete. Thank you. And in reference to your cryo, it looks like we'll have 180 pounds in each oxygen tank at SEP and 11 pounds in each hydrogen tank. And you're well above the single tank capability.
03 19 53 16
Bill Anders (LMP): Okay. Thank you.
03 20 22 22
Jerry Carr (CAPCOM): Apollo 8, Houston in the blind. Select OMNI Charlie. Over.
03 20 24 29
Jerry Carr (CAPCOM): Apollo 8, Houston. Apollo 8, Houston in the blind. We've lost all data on you and request you select us a good OMNI antenna; try Charlie. Over.
