Roger, Bill. We are reading you loud and clear now. We had an antenna problem down here. We had an unexpected switch of antenna, which probably caused your high gain to quit.
-
Mike Collins (CAPCOM)
-
Roger, Jim. When we lost our antenna down here, we interrupted your tape dump, so we are in the process of doing some rewinding and continuing the dump, in case Bill is wondering what is going on with the tape recorder.
-
Mike Collins (CAPCOM)
-
Roger. At 26 hours GET, we'll be switching our antennas back again at Madrid, and you can expect a glitch on your COMM system.
-
Jim Lovell (CMP)
-
I noticed that you skipped the IMU alignment for about 26 hours because we were still asleep. Do you want to include that again, or do you think it is required?
-
Mike Collins (CAPCOM)
-
Roger, Jim. We think it is going to be required prior to the next set of P23 sightings, and we're suggesting that it be put in at 27:45. We'll have a flight plan—a more complete flight plan update in here shortly.
-
Mike Collins (CAPCOM)
-
The tape dumps are complete; it's rewound. You can go ahead and record in low bit rate if you …
-
Mike Collins (CAPCOM)
-
Roger, Jim. We would like to take control of the tape for a few minutes to make sure that we got all that last dump. Over.
-
Mike Collins (CAPCOM)
-
Okay, Bill. This will be on page 2 dash 22 of your flight plan. For the command module pilot—I've already mentioned it to him—but at the top of the page, at about 27:45, actually, we would like him to do a P52, an IMU alignment, and then the P23 should be done as scheduled. Those four stars, Procyon, Regulus, Alphard, and Spica: we realize Alphard may not be too good a star, Regulus is about 3 degrees above the horizon, and Spica is at a 48-degree trunnion angle; so I guess what we are saying is if Jim has difficulty doing one set on each of those four stars, we suggest that he omit whichever one he is having difficulty with and pick it up by doing two sets on some other star that he likes. Over.
-
Mike Collins (CAPCOM)
-
All right. In the lower right hand corner of page 2-22, the passive thermal control attitude should read “pitch 224 degrees, yaw 020.”
-
Mike Collins (CAPCOM)
-
And on the next page, at about 29 hours, you can resume the normal flight plan. We would like to make one addition; at 29:30, add a waste water dump. Even though one is not really required at that time, we would like to get the dump out of the way so we can track you uninterruptedly without any dumping, you know, as we are coming up on midcourse correction number 3. Over.
-
Bill Anders (LMP)
-
No, it looks pretty good. We've been saving up some water of our own to dump here, so that will work out all right.
-
Mike Collins (CAPCOM)
-
Roger. We would like P00 in ACCEPT, please. We would like to send you up a P27. It's a LM state vector, going into the LM slot only, and we do not want you to transfer it over to the CSM.
-
Mike Collins (CAPCOM)
-
Okay. We got it. We're sending you a LM state vector, and we would like you not to transfer that vector over to the CSM slot.
-
Mike Collins (CAPCOM)
-
Stand by one, Bill. Bill, negative. Now that midcourse correction number 2 has been cancelled. Its magnitude was less than 1 foot per second, so we decided not to do it. Over.
-
Mike Collins (CAPCOM)
-
Apollo 8, Houston. Your 6910 pericynthian is still good plus or minus a minute, and we will get it down to a fine map measurement …
-
Mike Collins (CAPCOM)
-
Okay, Bill. We just got your readout on your voice tape, and we will be back with you on it shortly. Over.
-
Jim Lovell (CMP)
-
Houston, I'm going to be doing my alignment at this time. I'm in a good position for viewing the stars.
-
Mike Collins (CAPCOM)
-
Oh, good. Reading you loud and clear. One, two, three, four, five, five, four, three, two, one. Am I cutting in and out still? Over.
-
Mike Collins (CAPCOM)
-
Apollo 8, Houston. We are going to switch antennas at 28:20. Stand by for our blitz.
-
Frank Borman (CDR)
-
Roger, Houston. And we will start passing thermal control, and we are maneuvering to P23.
-
Jim Lovell (CMP)
-
Roger. Cislunar NAV accomplished. We did two sets on star 16, two sets on 22, and one set on 21.
-
Mike Collins (CAPCOM)
-
Roger, Bill. The one that we updated an hour or so ago, (i.e., pitch 224, yaw 020) is a good one.
-
Mike Collins (CAPCOM)
-
Apollo 8, Houston. We will change antennas in about 2 minutes. You can expect a glitch in your COMM.
-
Frank Borman (CDR)
-
Roger. We are dumping some water we collected here, and we are ready to dump the waste water down to 25 percent. Do you concur?
-
Mike Collins (CAPCOM)
-
Roger. We are getting geared up down here to do the first of the COMM checks. We will be doing an OMNI COMM check, which is on your flight plan, listed mode 7.8, and we will let you know when we are ready to proceed.
-
Mike Collins (CAPCOM)
-
Well, did you get the intergalactic news summary we sent up to you a couple of hours ago? It might have been during your rest period. We gave you a couple of football scores. One of them in particular was—I don't know if you copied that—Army 21, Navy 14. Over.
-
Mike Collins (CAPCOM)
-
Roger. The Cowboys were destroyed by the Cleveland Browns yesterday. The Pueblo crew is expected to be released. And I now hear our air-to-ground has got a lot of background noise. Stand by; we are going to go through these COMM test modes on page 223 of the flight plan. Over.
-
Frank Borman (CDR)
-
Houston, be advised that it looks like your Quindars are clipping your voice during your transmission.
-
Mike Collins (CAPCOM)
-
Roger, Understand. Are we still experiencing this intermittent condition that was there a few minutes ago?
-
Mike Collins (CAPCOM)
-
Apollo 8, Houston. We understand you are copying us. While we are trying to reestablish contact with you, would you put your optics switch to zero? We show you are drifting off in trunnion and request that you zero your optics.
-
Mike Collins (CAPCOM)
-
Apollo 8, Houston. We copy your optics zeroed, and how are you reading us now? Over.
-
Mike Collins (CAPCOM)
-
Apollo 8, Houston. We are down to 25 percent on your waste water dump and ready to terminate. Over.
-
Mike Collins (CAPCOM)
-
Roger, Our next COMM test is ranging only test. I have four switches I would like you to throw, which will cause you to lose voice communications for approximately 3 minutes. Over.
-
Mike Collins (CAPCOM)
-
Alright. The first one is S-band NORMAL mode voice, OFF; the second, S-band NORMAL mode PCM, OFF; the third, S-band NORMAL mode RANGING switch to RANGING; and fourth, the S-baud AUX tape switch, OFF. Over.
-
Mike Collins (CAPCOM)
-
Apollo 8, Houston. Request S-band NORMAL mode RANGING to OFF and S-band NORMAL mode PCM to PCM. I say again. S-band NORMAL mode RANGING, OFF; S-band NORMAL mode PCM to PCM.
-
Mike Collins (CAPCOM)
-
Apollo 8, Houston. Three communication switch positions. First, S-band AUX tape to DOWN-VOICE BACKUP; S-band NORMAL mode PCM, OFF; TELEMETRY INPUTS PCM, HIGH. I say again, S-band AUX tape to DOWN-VOICE BACKUP; S-band NORMAL mode PCM to OFF; TELEMETRY INPUTS PCM to HIGH.
-
Mike Collins (CAPCOM)
-
Apollo 8. Houston. Unable to copy. After about a minute of this configuration, we're going to return to normal voice, and at that time we should be able to hear you better.
-
Mike Collins (CAPCOM)
-
Apollo 8, Houston. Three switch positions. TELEMETRY INPUTS PCM switch to LOW; S-band NORMAL mode VOICE to VOICE; S-band NORMAL mode PCM to PCM. I say again, TELEMETRY INPUTS PCM switch, LOW; S-band NORMAL mode VOICE to VOICE; S-band NORMAL mode PCM to PCM. Over.
-
Mike Collins (CAPCOM)
-
Apollo 8, Houston. Requesting S-band NORMAL mode ranging to RANGING. I say again. S-band NORMAL mode ranging to RANGE. Over.
-
Mike Collins (CAPCOM)
-
Roger.

Apollo 8, Houston. Requesting S-band OFF state to OFF. This should put us back in the normal configuration. Over.
-
Mike Collins (CAPCOM)
-
Okay. S-band OFF state to OFF. That returns us to normal configuration, and we need a couple or items from you. First, the CMP and LMP status report (including PRD readings on all three crewmembers), and we'd like to know did you chlorinate the water after your last meal. Over.
-
Mike Collins (CAPCOM)
-
Apollo 8, Houston. We've switched on all the communications switch; functions are operating normally, Bill.
-
Frank Borman (CDR)
-
Mike, the PRD readings for the CDR are 4—that's 0.04, for the CMP is 0.64, and for the LMP is 0.25.
-
Frank Borman (CDR)
-
We're about in the right position for high gain; we wondered if you wanted to take a trial run and see if it will work. Or do you just want to wait and try it when they're supposed to go on the air with it?
-
Ken Mattingly (CAPCOM)
-
Okay. In reference the early TV, we're losing the high-gain antenna now, and it looks like the only way we would have gotten the early TV pass in anyhow was to send it to remote site and look at it there. So we're going to scrub that idea and we'll just pick up with the scheduled TV. The COMM checks that are remaining are the high-gain dependent type, and we'll put those off until the TV session is completed, and we are working on the fuel propellant curve for you now.
-
Ken Mattingly (CAPCOM)
-
Okay, Apollo 8. What we're going to do on the TV is to go ahead and let you crank it up as soon as we get back on the high-gain antenna, and it looks like—my guess is that this will be about 31:07, and we'll just use this to—as long as we have the coverage there. I have an update to your TLI plus 35 PAD. Now we have to correct a couple of times on there. So when you get that out, let me know and I'll read it to you.
-
Ken Mattingly (CAPCOM)
-
Okay. On the TLI plus 35 pass, the update I want to give you is the last three lines in the block: the EMS range to go 13084 35985 0984217. Over.
