Mike Collins (CAPCOM): Good show. Thank you.
00 03 43 25
Mike Collins (CAPCOM): Apollo 8, Houston.
00 03 43 31
Bill Anders (LMP): Go ahead, Houston.
00 03 43 32
Mike Collins (CAPCOM): we would like to take control of the DSE for a while, Bill.
00 03 43 35
Bill Anders (LMP): Go ahead.
00 03 43 36
Mike Collins (CAPCOM): Thank you.
00 03 43 54
Mike Collins (CAPCOM): Apollo 8, Houston. We would like to get an approximate GET of your SEP maneuver to use for our ephemeris tracking data.
00 03 44 06
Frank Borman (CDR): Roger. It was 3 hours 40 minutes zero seconds.
00 03 44 10
Mike Collins (CAPCOM): Good, 03:40 and a foot and a half—feet per second. Right?
00 03 44 15
Frank Borman (CDR): Roger. About that —
00 03 44 16
Mike Collins (CAPCOM): Okay.
00 03 44 18
Frank Borman (CDR): — We have the—Mike, we have the exact callout here for you and a burn status report.
00 03 44 22
Mike Collins (CAPCOM): Alright.
00 03 44 28
Frank Borman (CDR): Alright, DELTA-V_X minus 00011, DELTA-V_Y plus 0002, DELTA-V_Z minus 0002, roll 0, pitch 180, yaw 0. Over.
00 03 44 46
Mike Collins (CAPCOM): Roger, Apollo 8.
00 03 46 25
Mike Collins (CAPCOM): Apollo 8, Houston.
00 03 46 29
Frank Borman (CDR): Go ahead, Houston. Apollo 8.
00 03 46 31
Mike Collins (CAPCOM): Roger. At your convenience, would you please go P00 and ACCEPT? We're going to update to your W matrix. And also when you get a chance, we would like to know about the SLA panels. Did they all depart? And do you have any comments about the SLA?
00 03 46 43
Frank Borman (CDR): They all departed, and they worked fine.
00 03 46 47
Mike Collins (CAPCOM): Okay. Thank you.
00 03 46 58
Frank Borman (CDR): We are in P00 and ACCEPT.
00 03 47 00
Mike Collins (CAPCOM): Thank you.
00 03 48 26
Frank Borman (CDR): Houston, Apollo 8. Will you give us the information when you want us to stop the venting and so on?
00 03 48 32
Mike Collins (CAPCOM): Apollo 8, Houston. Roger.
00 03 50 39
Mike Collins (CAPCOM): Apollo 8. Houston.

Frank Borman (CDR): Go ahead, Houston.
00 03 50 44
Mike Collins (CAPCOM): Roger. What is the venting information are you inquiring about: the O₂ flow high out through the waste tank or waste compartment, or are you talking about your evaporator?
00 03 50 53
Frank Borman (CDR): Evaporator. We are configuring now to stop boiling.
00 03 50 56
Mike Collins (CAPCOM): Okay.
00 03 50 58
Mike Collins (CAPCOM): We concur in that.
00 03 51 02
Mike Collins (CAPCOM): Apollo 8, Houston. You can go back to BLOCK. We have gotten in the load to the W matrix update.
00 03 51 10
Frank Borman (CDR): Roger.
00 03 51 58
Frank Borman (CDR): Houston, Apollo 8. The back pressure valve is closed, and the water flow is OFF.
00 03 52 03
Mike Collins (CAPCOM): Back pressure valve closed, and water flow OFF. Thank you.
00 03 53 04
Frank Borman (CDR): Houston, Apollo 8 here.
00 03 53 05
Mike Collins (CAPCOM): Apollo 8, Houston. Go ahead.
00 03 53 07
Frank Borman (CDR): Roger. It looks like I might have to do a couple more small maneuvers to stay away from the front of this S-IVB, the way we are ending up now. Do you want me to do these with our P47 if we have to do them?
00 03 53 19
Mike Collins (CAPCOM): Standby one, Frank.
00 03 53 28
Mike Collins (CAPCOM): That's affirmative, Frank, on this P47.
00 03 53 30
Frank Borman (CDR): Okay. And give me the time again when it starts to dump, please.
00 03 53 35
Mike Collins (CAPCOM): Roger. We're working on an exact GET of that, Frank.
00 03 53 48
Frank Borman (CDR): Roger.
00 03 54 54
Mike Collins (CAPCOM): Apollo 8, Houston.
00 03 54 57
Frank Borman (CDR): Go ahead.
00 03 54 58
Mike Collins (CAPCOM): I'd like to give you some idea about your trajectory. It looks like a midcourse correction number 1, projected out to TLI plus 6 hours, would be only 7 feet per second. So, of course, any further maneuvers you do would add to that, which is probably good.
00 03 55 24
Frank Borman (CDR): I just want to stay from away from in front of this thing.
00 03 55 27
Mike Collins (CAPCOM): Roger. We concur. Looks like it is chasing you, huh?
00 03 55 32
Frank Borman (CDR): Yes.
00 03 55 53
Bill Anders (LMP): OMNI D.
00 03 56 01
Frank Borman (CDR): Boy, it's starting to vent now, blowing down.
00 03 56 07
Mike Collins (CAPCOM): Apollo 8, Houston. Say again.
00 03 56 09
Frank Borman (CDR): The S-IVB is really venting.
00 03 56 13
Mike Collins (CAPCOM): Roger. Understand; that is supposedly a non-propulsive vent. The big blowdown maneuver, it starts maneuvering to blowdown attitude at 04:44:55, and the vent occurs at 05:07:55.
00 03 56 32
Frank Borman (CDR): 05:07:55.
00 03 56 34
Mike Collins (CAPCOM): Roger.
00 03 56 35
Frank Borman (CDR): That is the nonpropulsive vent, but it's pretty spectacular. It's spewing out from all sides like a huge water sprinkler.
00 03 56 45
Mike Collins (CAPCOM): Roger. Get some pictures of it.
00 03 56 48
Frank Borman (CDR): We are.

00 03 57 07
Frank Borman (CDR): Say again that big vent time, so I can write it down please, Houston.
00 03 57 11
Mike Collins (CAPCOM): Roger. Big vent time 05:07:55, and it will start maneuvering to vent attitude beginning at 04:44:55. Bill has got the tape recorder back.
00 03 57 32
Frank Borman (CDR): Thank you. Roger.
00 03 58 31
Frank Borman (CDR): We're receiving VHF music now, Houston. Thank you.
00 03 58 35
Mike Collins (CAPCOM): Yes, you took the words right out of my mouth, Frank, and we would like to know also how far away from the S-IVB you are now.
00 03 58 48
Frank Borman (CDR): I guess we are between 500 to 1000 feet.
00 03 58 51
Mike Collins (CAPCOM): Roger.
00 03 58 57
Frank Borman (CDR): Herb Alpert seems pretty good.
00 03 59 00
Mike Collins (CAPCOM): Roger.
00 04 02 04
Frank Borman (CDR): Houston, Apollo 8.
00 04 02 06
Mike Collins (CAPCOM): Apollo 8, Houston.
00 04 02 10
Frank Borman (CDR): Roger. I believe we are going to have to vent or thrust away from this thing; we seem to be getting closer.
00 04 02 18
Mike Collins (CAPCOM): Roger. Understand, Frank; go ahead whenever—just give us some idea of when you did it and how much.
00 04 02 24
Frank Borman (CDR): Roger.
00 04 02 32
Mike Collins (CAPCOM): Apollo 8, Houston. Could you stand by one? We are working on something here.
00 04 02 37
Frank Borman (CDR): Okay.
00 04 05 10
Mike Collins (CAPCOM): Apollo 8, Houston.
00 04 05 16
Mike Collins (CAPCOM): Apollo 8, this is Houston. Over.
00 04 05 39
Mike Collins (CAPCOM): Apollo 8, this is Houston. Over.
00 04 05 40
Frank Borman (CDR): You are loud and clear, Mike. Go ahead.
00 04 05 43
Mike Collins (CAPCOM): Okay, Frank. On your additional separation maneuver, we recommend that you make a radial burn, point your plus X-axis toward the earth, and thrust minus X for 3 feet per second. Over.
00 04 05 57
Frank Borman (CDR): I don't want to do that; I'll lose sight of the S-IVB.
00 04 06 01
Mike Collins (CAPCOM): Okay. The reason we want a radial burn is to increase your midcourse correction so we can use the SPS. Stand by on it.
00 04 06 33
Mike Collins (CAPCOM): Apollo 8, Houston.
00 04 06 35
Frank Borman (CDR): Go ahead.
00 04 06 36
Mike Collins (CAPCOM): How close to a radial burn can you get without losing sight of the S-IVB, Frank?
00 04 06 41
Frank Borman (CDR): Well, I don't know because I can't see the earth now, Mike.
00 04 06 44
Mike Collins (CAPCOM): Okay.
00 04 06 51
Frank Borman (CDR): We can pitch down some. Jim has the earth in the optics so we could pitch some and get pretty close to one, I guess.
00 04 07 31
Mike Collins (CAPCOM): Apollo 8, Houston.
00 04 07 32
Frank Borman (CDR): Go ahead, Houston. Apollo 8.
00 04 07 34
Mike Collins (CAPCOM): We can give you a pitch gimbal angle on radial direction if that would be a help. It's 181 degrees; pitch gimbal angle would be exactly radial at 4 hours and 10 minutes. I don't know whether that solves your visibility problem or not.
00 04 07 46
Frank Borman (CDR): 181?
00 04 07 47
Mike Collins (CAPCOM): That's affirmative.
00 04 07 54
Frank Borman (CDR): Well, then zero would be just as good, wouldn't it?
00 04 08 05
Mike Collins (CAPCOM): Frank, if you use zero, then make the SEP if possible in the plus X thrusters. That's the direction of the burn we'd like.
00 04 08 13
Frank Borman (CDR): Well, can't do that. I'll thrust right square into that S-IVB.
00 04 08 16
Mike Collins (CAPCOM): Yes, okay. Understand.
00 04 08 22
Frank Borman (CDR): What will he maneuver to as far as the gimbal angle for his blowdown?
00 04 09 03
Mike Collins (CAPCOM): Apollo 8, Houston. At blowdown, that S-IVB should be oriented to perform a retrograde blowdown along the local horizontal.
00 04 09 14
Frank Borman (CDR): Okay.
00 04 09 22
Mike Collins (CAPCOM): Is it still chasing? Does it look like it is closing on you, Frank?
