Roger. We copy, and we are reading you loud and clear now, Bill. On your map update, did you copy that that I gave you previously?
-
Mike Collins (CAPCOM)
-
This is a map update for REV's 4/5: LOS 76:59:59, sunrise 77:09:06, prime meridian 77:15:47, AOS 77:45:50, sunset 78:22:03; remarks: IP-1, acquisition time for CP2 is 77:29:42, IP-1 time closest approach for target B-1 78:10:25. Over.

Roger. LOS 76:59:59, sunrise 77:09:06, 77:45:47, 77:45:50, 78:22:03; IP-1, CP2 77:29:42, IP-1 TCA for B-1 78:10:25.
-
Mike Collins (CAPCOM)
-
That's right, and the prime meridian time is 77:15:47, and you got your computer back. We've got a good P27 update.
-
Mike Collins (CAPCOM)
-
Roger. On your back pressure valve, we would like to know how long after you closed the back pressure valve the first time—how long it was from the time you closed it until the time you started the reservicing? We would like for you to wait about 15 minutes to prevent any ice from forming due to flash freezing. Over.

Apollo 8, Houston. We show that you closed it this last time about 4 minutes ago, so we would like you to wait another 15 minutes and then try to reservice it again at that time and then go to AUTO. Over.
-
Mike Collins (CAPCOM)
-
Roger. Thank you. The TEI 4 PAD which you have is still valid. We will have a TEI 5 PAD for you shortly.
-
Bill Anders (LMP)
-
Roger. Be advised we are presently in steam pressure MANUAL, and we're in H2O flow AUTO, and are now in H2O flow OFF, as of about 5 seconds ago.
-
Mike Collins (CAPCOM)
-
Apollo 8, Houston. On your television update, we propose that you start the TV at the flight plan time of 85 hours 37 minutes and simply extend the stop time a few minutes. You're currently scheduled to stop at 86 hours, and we would like to keep it going until the terminator, which should be approximately 86:14. Over.
-
Mike Collins (CAPCOM)
-
Frank, I know you are busy up there. We've got the daily news for you whenever and if ever you'd like to hear it.
-
Mike Collins (CAPCOM)

Okay. TEI 5, SPS/G&N: 47 correction—45701, minus 043, plus 116 079:21:26.03. Are you with me so far?

Roger. Here we go: TEI 5, SPS/G&N 45701, minus 043, plus 116 079:21:26.03, plus 31171, minus 00767, minus 00214 180 017 001, NA, plus 00188 31181 259 31003 40 2711 398 033, down 043, left 23, plus 0832, minus 16500, plus 12956 36208 146:39:44. Set stars are the same; ullage—we'd like—do you have any objection to using four quads for 15 seconds?
-
Frank Borman (CDR)
-
Okay. We'd like to just go ahead and use four quads all times, unless we get a lot shorter on fuel than we are now.
-
Mike Collins (CAPCOM)
-
That readback is correct, Frank, and we'd like to advise that the voice quality on that high bit rate is excellent. Over.
-
Mike Collins (CAPCOM)
-
Roger for Bill. He can go ahead and do his standard reservice on the water now. It's looking good.
-
Mike Collins (CAPCOM)
-
Roger. We are still dumping your tapes. The voice quality on high bit is coming through superb, and you are GO for the next rev. And we would like to get a brief status report on your rest between 60 hours and LOI 1, just to fill in some information for us.
-
Frank Borman (CDR)
-
We're tired right now, but we will have to wait until TEI before we get back to the regular cycle.
-
Bill Anders (LMP)
-
Okay, Houston. The water boiler has been reserviced, back pressure valve CLOSED for 1 minute, water ON for 2, and it's now steam pressure AUTO, H2O flow AUTO.
-
Bill Anders (LMP)
-
If we have a problem, a similar problem, again on the back side in the sunlight, might be a good idea to crank the secondary loop until we have AOS. What do you think about that?
-
Mike Collins (CAPCOM)
-
Roger, Jim. In regard to your evaporator, we feel that if you do have a similar problem next time on the back side in sunlight, check the evaporator outlet temperature, and if it gets above 60, we concur that it would be a good idea to bring up the secondary loop. Over.
-
Mike Collins (CAPCOM)
-
Apollo 8, Houston. When we say bring up the secondary loop, we mean bring up the evaporator only on the secondary loop. Copy?
-
Mike Collins (CAPCOM)
-
Roger. We got the Interstellar Times here, the December 24 edition. Your TV program was a big success. It was viewed this morning by most of the nations of your neighboring planet; the earth. It was carried live all over Europe, including even Moscow and East Berlin, also in Japan and all of North and Central America and parts of South America. We don't know yet how extensive the coverage was in Africa. Are you copying me all right? Over.
-
Frank Borman (CDR)
-
You are loud and clear.
-
Mike Collins (CAPCOM)
-
Good. San Diego welcomed home today the Pueblo crew in a big ceremony. They had a pretty rough time of it in the Korean prison. Christmas cease-fire is in effect in Viet Nam, with only sporadic outbreaks of fighting. And if you haven't done your Christmas shopping by now, you better forget it.
-
Jim Lovell (CMP)
-
Mike, I think I can say it without contradiction, it's been a mighty long dry spell up here.
-
Mike Collins (CAPCOM)
-
We will get you the number after a while on your water dump. It looks like the quantity isn't increasing very slightly, and we're considering not only the quantity in regard to the dump, but also its effects on the trajectory relative to TEI and so forth, but we will have a good answer for you shortly.
-
Frank Borman (CDR)
-
We are not just thinking about the waste water tank: we're thinking about some other kind of water that has to get dumped out of the spacecraft, slightly used water.
-
Mike Collins (CAPCOM)
-
Roger. We have about three and a half minutes to LOS. We give you back the DSE under your control, and in regard to your water dump, we are tentatively predicting a waste water tank dump at about 80 hours GET and any other dumps are at your discretion, any time you would like to make them.
-
Mike Collins (CAPCOM)
-
People listening to the high bit rate down here say it's like sitting in your living room listening to good hi-fi.
-
Mike Collins (CAPCOM)
-
Apollo 8, Houston. Coming up on 2 minutes to LOS. We got a good reservice on the primary evaporator, and everything is still looking very good down here.
-
Mike Collins (CAPCOM)
-
Apollo 8, Houston. One minute to LOS. Are you still reading us loud and clear?
-
Mike Collins (CAPCOM)
-
Okay, fine. We've been noticing a little bit of increase in our background noise as you approach backside.
-
Bill Anders (LMP)
-
Roger. Looks like the evaporator—looks like the evaporator is holding okay, or at least it is trying to. It dropped the temperature down to about 32, and now it's come back up again and stabilized at about 42 degrees.
-
Jim Lovell (CMP)
-
Roger. Houston, this is Apollo 8. What we are doing on the control point tracking—I managed to look for a CP-1 at the same time we were trying to do a CP-2 on this rev. I picked up two marks which are just as small, but more easily recognizable, than the ones that were given to me. I know that I can repeat the process and pick the same small point on the next rev. Now I can try to look for the control points that are written down, but I think that I have better control over the ones that we have.
-
Jim Lovell (CMP)
-
Roger. One more point: the control point times which you have given me are a little bit off, and I can notice by comparing these maps that these maps are not too well aligned either.
-
Mike Collins (CAPCOM)
-
Roger. These two small points that you can repeat your marks on: will you be able to identify those precisely on a map? Over.
-
Jim Lovell (CMP)
-
That's affirmative; that is why I picked them. They are both—they're both very prominent features, and they are both very small craters about the same size as the ones we are looking for, but I can pinpoint them on a map.
-
Jim Lovell (CMP)
-
Roger. One more comment: as it offered a lot of controversy at data priority meetings, it looks like 10 degrees pitch up is the best attitude to obtain the horizon so that you can follow the landmark down through the scanning telescope. If you pitch down any more, full up trunnion will not get the horizon, and the horizon is a great help in leading yourself into the control point.
-
Mike Collins (CAPCOM)
-
Jim, we concur with your use of the two small craters which you can repeatedly mark on and find on the map; and also if you will give us your new latitudes and longitudes, we can compute for you a time of closest approach to those points with the spacecraft 10 degrees pitched-up. Over.
-
Jim Lovell (CMP)
-
Roger, Houston. CP-1 latitude minus 606269, longitude over 2, minus 78954, altitude plus 00152; for CP-2 latitude minus 09638, longitude over 2, plus 81691, altitude minus 00007. I tried to get CP-3 at the same pass, but I let it go by to get set up for this first track at the landing site.
-
Mike Collins (CAPCOM)
-
Roger, Houston. CP-1: would you say again the latitude, and on CP-2, say again the longitude CP-2, please?
-
Jim Lovell (CMP)
-
Roger. CP-1 latitude minus 06269; that is the latitude; and for longitude over 2 for CP-2, plus 81691.
-
Jim Lovell (CMP)
-
And it appears so far, Houston, that no spacecraft pitch motion is required to get five marks on the target in plenty of time.
-
Mike Collins (CAPCOM)
-
Roger. I am about 15 minutes early with the TEI fix update and the map update. I will have them here whenever it's convenient for you to copy.
-
Mike Collins (CAPCOM)
-
Roger. We would like to ask you to stop using AUTO OPTICS on the pseudo landing site. It's necessary that we send you up a P27 to update the RLS values stored in the computer. Over.
-
Mike Collins (CAPCOM)
-
Roger. If you would go to P00 and ACCEPT, please, we are going to send you a P27 load which will update an RLS value which will be followed by a procedural change, Jim, we will give you later; and AUTO OPTICS should be working shortly.
-
Mike Collins (CAPCOM)
-
Apollo 8, Houston. We are also sending you up a state vector update at the same time.
-
Mike Collins (CAPCOM)
-
Apollo 8, Houston. Roger. I have updates, a map update for REV 5/6, and TEI 6 update. Which would you like first?
-
Mike Collins (CAPCOM)
-
Okay. Map update for REV 5/6. LOS 78:58:49, sunrise 79:08:07, prime meridian 79:14:30, AOS 79:44:36, sunset 80:21:05; IP-1, time of closest approach to target B-1 80:09:00. Now your two new control points that Jim gave us: control point number 1, acquisition 79:10:32, control point number 2, acquisition 79:23:14. Over.
-
Mike Collins (CAPCOM)
-
Okay, Bill. Before we read the big TEI update here, I'd like to give Jim briefly a procedure for P22. When he comes to NOUN 89, we request that he do a VERB 34 ENTER. Do not proceed, and by so doing then, he will not incorporate the lat and longitude from his mark, and he will not change the reference value of the landing site, and we will solve this AUTO OPTICS problem. Over.
-
Bill Anders (LMP)
-
Let me see if I have this correct, Mike. When flashing 0689 comes up with the latitude and longitude information, I will not proceed but will go to VERB 34 and terminate. Is that correct?
-
Mike Collins (CAPCOM)
-
Yes, that is affirmative. Do a VERB 34 ENTER instead of a PROCEED. And that will -
-
Jim Lovell (CMP)
-
Houston, is this technique true for both the node control point AUTO OPTICS on P25?
-
Jim Lovell (CMP)
-
Okay. Roger. True for the code AUTO OPTICS and no landmark. I'll proceed instead of going on—or I'll use 34 instead proceeding on 89.
-
Mike Collins (CAPCOM)
-
Roger. Thank you, Jim, and I have the TEI 6 hour when you are ready—or TEI number 6.
-
Mike Collins (CAPCOM)
-
Roger. I'm glad you are ready to copy TEI number 6. I've got one last comment for Jim before you do so. The VERB 89—or correction—the NOUN 89 we are talking about is the one that he gets after marking. There are two NOUN 89's, one prior to marking and one after, and our procedure references NOUN 89 after marking. Over.

Bill Anders (LMP)

Thank you, Michael. As a matter of interest, these side windows are so hazy that when the sun shines on them, they just about—they are real poor for any visual observation or photography—heads-up.
-
Mike Collins (CAPCOM)
-
Roger. The last state vector updates we sent you, Jim, was to the LM slots, and you will have to transfer that over to the CSM slots using VERB 47 ENTER. Over.
-
Mike Collins (CAPCOM)
-
Roger. Bill has got his tape recorder back, and we noticed during that last dump, it was all in low bit rate. We wonder whether that was intentional or not? Over.
-
Bill Anders (LMP)
-
Roger. We didn't have much to say; we couldn't see out of the windows very well, Mike.
-
Mike Collins (CAPCOM)
-
Roger, Bill. This next time around into the sunlight, we do not expect any problem with the primary evaporator. If it does start drying out, we think it is best just to close the back pressure valve, and there is no need to activate the secondary boiler. Over.
-
Mike Collins (CAPCOM)
-
Apollo 8, Houston. We are suggesting you disregard the 60 degree limit, and let it go ahead and rise up above 60. There is no need to activate the secondary. Over.
-
Mike Collins (CAPCOM)
-
Roger. We have about 4-1/2 minutes left before we have LOS; we'd like your last PRD readout. Over.
-
Jim Lovell (CMP)
-
Stand by. The commander is asleep; we'll get his when he wakes up. The LMP is still 6 … 0.64, C is 9, CMP is 0.09.
-
Mike Collins (CAPCOM)
-
Apollo 8, Houston. About 40 seconds to LOS, and everything's looking good down here.
-
Mike Collins (CAPCOM)
-
Reading you very weak but—a lot of background noise. Welcome back around. How are you reading us?
-
Jim Lovell (CMP)
-
Roger, Houston. A few words on our optics tracking system. I used AUTO OPTICS for control points 1 and 2 on the backside, and they worked beautifully, tracked both the targets for me. And I went to the control point 3 as designated in our orbital control book to see the latitude and longitude that was given to me and used AUTO OPTICS to track that particular coordinate system, and it was very close to the actual tracking plot. I picked the mark there where I did a final marking and recorded latitude and longitude. I'm now about to come up on the landing site and using AUTO OPTICS in the coded input to see how that works.
-
Mike Collins (CAPCOM)
-
Roger. We know you're busy so we are not going to bother you. We are watching your progress on the DSKY. You are looking good; all your systems are looking good, and we have maneuver PAD's for you any time at your convenience.
-
Jim Lovell (CMP)
-
Mike, there are an awful lot of objects down on the landing site. It would just warm up Jack Schmidt's heart. The AUTO OPTICS are tracking perfectly on the target, and the two high peaks stand out beautifully. I have a beautiful view of it. The first I've seen just barely beneath the vertical now, and the second one coming up—It's just a grand view!
-
Bill Anders (LMP)
-
Jack, the information—The triangles that we see now are from the first IP, second IP, and the B-1 are just right, I think, for landing conditions. The shadows aren't too deep for you to get confused, but the land has texture to it, and there are enough shadows there to make everything stand out.
-
Bill Anders (LMP)
-
If Jack's listening, tell him that the optical may be doing all right, but the eyeball is having a little trouble looking through all this smear on the windows.
-
Mike Collins (CAPCOM)
-
Roger. Understand the optics are doing better than the eyeballs. How about the cameras?
-
Bill Anders (LMP)
-
We always have the same smear to look through. The rendezvous windows are okay, but they're so small and looking in the wrong directions here so far.
Expand selection down Contract selection up -
Bill Anders (LMP)
-
It certainly looks like we're picking the more interesting places on the moon to land in. The backside looks like a sand pile my kids have been playing in for a long time. It's all beat up, no definition. Just a lot of bumps and holes.
-
Bill Anders (LMP)
-
The area we're over right now gives some hint of possible volcanic, though I really can't eyeball it at the moment to pin that down. There are some craters and buildups that just definitely suggest volcanic activity.
-
Mike Collins (CAPCOM)
-
Roger, Jim. We have you on the high-gain antenna. We'd like you to take the DSE and dump it over.
-
Mike Collins (CAPCOM)
-
That's affirmative, Jim. We'd like to—stand by one, and I'll tell you when to go to P00 and ACCEPT.
-
Mike Collins (CAPCOM)
-
Jim, would you please go to P00 in ACCEPT, and we'll send you a P27 and run a state vector update.
-
Jim Lovell (CMP)
-
Houston, this is Apollo 8. We have a little piece of useful information if you're interested in deliberating over it.
-
Jim Lovell (CMP)
-
Roger. Our first control point is very near the terminator, and as the optics were tracking it, I had occasion to watch the sun come up. And at about 2 minutes before sunrise, you get—the limb begins to brighten up into sort of a fine white haze, a fine glow completely over the space just behind the limb.
-
Mike Collins (CAPCOM)
-
Roger. I understand. About 2 minutes before the sun comes up, you get a fine white haze radiating out from behind the limb. How far out does it extend?
-
Jim Lovell (CMP)
-
It goes up quite a ways. It takes a fan shape, unlike the sunrise on earth where the atmosphere affects it. This just sort of is a complete haze all over the local area. It's concentrated at the exact spot where the sun comes up at ignition and then goes away from the sun spots. Very interesting.
-
Mike Collins (CAPCOM)
-
Okay. When you get your—before you get your map book out, the Houston COMM TECHS have got a little word for an old ex-CAP COMM. They say they consider you in NONREMOTE. Over.
-
Mike Collins (CAPCOM)
-
Okay. Your map update for REV 6/7: LOS 80:57:24, sunrise 81:06:57, prime meridian 81:13:02. Are you with me?
-
Mike Collins (CAPCOM)
-
AOS 81:43:05, sunset 82:13:54. Remarks: IP-1 TCA for B-1 82:07:39, and now I've got four more times for you which—acquisition times for when various things come over the horizon. Over.
-
Mike Collins (CAPCOM)
-
Okay. Control point 1, acquisition time 81:09:05; control point 2, acquisition time 81:21:48; control point 3, acquisition time 81:43:17. B-1 acquisition time 82:03:54. And I say again all those ACQ times are when they first come over the horizon. Over.
-
Bill Anders (LMP)
-
Just a matter of general interest, Houston: everybody is feeling good, and the CDR is taking a snooze.
-
Mike Collins (CAPCOM)
-
Roger. Glad to hear it. We were just talking about a water dump down here. We've got one coming up, and it looks like on this REV prior to the time around LOS or just prior to LOS, would be a convenient time to do it. Do you concur?
-
Mike Collins (CAPCOM)
-
That's affirmative, and we'd also be interested in any comments about what these various dumps have done to your optics, if anything, and how long the effects last after a dump.
-
Bill Anders (LMP)
-
Don't seem to have done anything to the optics, but they've definitely got in some of the windows. There are a few little chunks of ice on window number 1, which is nearest the vent, and also on window number 5 a little bit; windows 2 and 4 remain amazingly clear.
-
Mike Collins (CAPCOM)

Alright. Weight 45701, minus 040, plus 157 083:18:20.80, plus 32346, minus 01168, plus 05730. Are you with me so far? Over.
