030:22:29 Borman: Houston, this is Apollo 8.
030:22:33 Mattingly: Go ahead, Apollo 8.
030:22:37 Borman: Oh, hi, Ken. How are you doing?
030:22:39 Mattingly: Roger. Fine. How you been?
030:22:41 Borman: Is this Jerry?
030:22:42 Mattingly: This is Ken.
030:22:44 Borman: Hey, listen, we still have this TV coming up here - let's see - 31:20?
030:22:52 Mattingly: Affirmative. [Pause.]
030:23:00 Borman: 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?
030:23:18 Mattingly: Okay. Stand by on that.
030:23:23 Borman: Okay
030:30:25 Anders: Houston, Apollo 8. Over.
030:30:27 Mattingly: Go ahead, Apollo 8.
030:30:33 Anders: Roger. Could you ask the GNC to give us an update on our prop[ellant] quantity, please?
030:30:41 Mattingly: Wilco. You're referring to the RCS?
030:30:46 Anders: Roger. [Pause.]
030:30:53 Anders: If you'll give it to me kinda slow, I'll plot it.
030:30:56 Mattingly: Roger. It's coming now
030:35:13 Mattingly: Apollo 8, Houston.
030:35:19 Borman: Go ahead, Houston. Apollo 8.
030:35:20 Mattingly: Okay. In reference [to] 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 [a] 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.
030:35:53 Borman: Thank you
030:41:50 Mattingly: Apollo 8, Houston.
030:41:53 Borman: Go ahead, Houston. Apollo 8.
030:41:54 Mattingly: 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.
030:42:38 Borman: Go ahead.
030:42:40 Mattingly: Okay. On the TLI plus 35 PAD, the update I want to give you is the last three lines in the block: the EMS range to go, 1308.4, 35985, 098:42:17. Over
030:43:11 Borman: Understand. Range to go 1308.4, 35985, 098:42:17.
030:43:21 Mattingly: Affirmative
030:44:54 Mattingly: Apollo 8, Houston. We are about to have a handover to Goldstone, and our downlink isn't improved then. I don't know if you'll notice any difference in the uplink or not. [Long pause.]
030:45:52 Mattingly: Apollo 8, Houston. [No answer.]
030:46:44 Mattingly: Apollo 8, Houston.
030:46:48 Borman: Go ahead, Houston. You are loud and clear.
030:46:51 Mattingly: Okay. We have switched sites over to Goldstone now. I don't know if you can tell any difference in our uplink.
030:47:01 Borman: Negative. You're about the same.
030:47:03 Mattingly: Okay. You have cleared up quite a bit. Sounds a lot better to us.
030:47:08 Borman: Okay
030:49:35 Mattingly: Apollo 8, Houston.
030:49:38 Borman: Go ahead, Houston. Apollo 8.
030:49:40 Mattingly: I have some RCS quantity data for you. We are all set up to receive the TV whenever you get [the] High Gain [Antenna] looking at us. [Expected to be in about 16 minutes.]
030:49:51 Borman: Okay. Let me get the [RCS Propellant usage] chart out here. [Long pause.]
030:50:20 Borman: Go ahead with the quad propellant quantities, please.
030:50:25 Mattingly: Okay, Apollo 8, Alpha, I have 225 pounds, 74 percent; Bravo, 240...
030:50:41 Borman: Slower, please.
030:50:42 Mattingly: Roger. I will repeat. Alpha, 225, 74 percent; Bravo, 240 pounds, 79 percent; Charlie 236, 78 percent; Delta, 238, 79 percent. I would like to remind you on the TV that we need narrow beam width when you get up in High Gain. Over.
030:51:45 Borman: Roger. Understand.

This is Apollo Control at 31 hours, 5 minutes into the mission. We are standing by at this time to receive the first television transmission from the spacecraft. Now there is a certain amount ot uncertainty just as to when that signal will be received at the station at Goldstone and transmitted to Houston. Now the spacecraft at the present time is in a slow roll as part of the Passive Thermal Control program to maintain temperatures, and as soon as the High Gain Antenna is in the proper position we expect to begin getting pictures. We will stand by and pick up the picture as soon as we have any solid video lock on them. At this time our estimate is that it will be about one minute before we pick up our TV transmission. When we begin this television transmission the spacecraft will be at a range from Earth of about 120,623 nautical miles [223,393 km]. We will be traveling at a velocity of about 4,668 feet per second [1,423 m/s]. We are still standing by to receive the first indications that a picture is about to come through. We now estimate about 15 more seconds. As I said before there could be some variation in that depending on the position of the High Gain Antenna. We have gotten a call from the crew. We will pick that up and then stand by for pictures. That sounded like Bill Anders putting in a call to the Control Center here. We still do not have pictures. We will continue to monitor. We are getting a good signal through from Goldstone, but we still have not received any video from, from the spacecraft. Now we will continue to monitor and also to monitor the audio loop for any conversations from the crew.
031:07:18 Borman: Houston, how do you read? Apollo 8.
031:07:20 Mattingly: Loud and clear, Apollo 8.
031:07:24 Borman: Okay. Thank you
031:09:57 Borman: Houston, Apollo 8. How do you read?
031:09:59 Mattingly: Apollo 8. Loud and clear and standing by.
031:10:04 Borman: Say again.
031:10:05 Mattingly: We read you loud and clear, and we're standing by.
031:10:09 Borman: Okay. [Long pause.]
Are you receiving television now? [Pause.]
031:10:36 Mattingly: Apollo 8, Houston. We just got it.
031:10:43 Borman: You are getting it? [Pause.]
031:10:52 Mattingly: Okay, Apollo 8. We have a good picture.
031:10:54 Borman: We're rolling a...
031:10:57 Borman: Okay. We're rolling around to a good view of the Earth, and as soon as we get to the good view of the Earth, we'll stop and let you look out the window at the scene that we see. Jim Lovell's down in Lower Equipment Bay preparing lunch, and Bill is holding a camera here for us both.
031:11:29 Borman: Bill's going to take the camera down to the Lower Equipment deck with Jim:
031:11:34 Mattingly: Roger.
031:11:37 Mattingly: Okay. We're getting a pretty good picture, but if you'd move it a little slower - every time you move it around, it breaks up the scan.
031:11:47 Borman: We gotcha.
031:11:49 Mattingly: [Laughter.]
031:11:54 Lovell: This is known as preparing lunch and doing P23 at the same time. [Pause.]
031:12:18 Mattingly: You've got everybody standing on their heads down here.
031:12:23 Borman: How go - Has he got it turned upside down? You've got the wrong REFSMMAT
031:12:31 Mattingly: Well, we all have our problems. [Pause.]
031:12:44 Borman: How is the picture now, Houston?
031:12:46 Mattingly: That's really good.
031:12:52 Borman: Okay. Now we are coming up on the view that we really want you to see. That's the view of the Earth, and if you will break for just a minute, Bill is going to put on the large lens. So we will be right back with you.
031:13:03 Mattingly: Okay. Thank you. [Long pause.]
And we momentarily lose our picture while this lens change is in progress. We will stand by for that shot of Earth.
031:13:54 Borman: Houston, we are now showing you a view of the Earth through the telephoto lens
031:14:00 Mattingly: Okay. We're not receiving a picture right now. [Pause.]
031:14:08 Borman: How about now? [Pause.]
031:14:14 Mattingly: Okay. We don't have a picture yet. [Pause.]
031:14:27 Borman: You seeing anything at all, Houston? [Pause.]
031:14:36 Mattingly: Okay, Apollo 8. We don't have a picture yet.
031:14:46 Borman: Alright. We'll put the other lens back on, and we will show you that.
031:14:50 Mattingly: Apollo 8, how about standing by on that for just a minute. Let's check our ground link. [Pause.]
031:15:06 Mattingly: Apollo 8, we have a picture now.
031:15:10 Borman: Okay. Let's try the other lens again then, once again.
031:15:13 Mattingly: Okay. Thank you. [Long pause.]
031:15:30 Borman: Do you have a picture now?
031:15:31 Mattingly: That's negative. [Long pause.]
031:15:45 Mattingly: Apollo 8, [garbled.]
031:15:54 Borman: Okay. Do you have anything. Houston? We have it on the Earth.
031:15:58 Mattingly: We are having no joy.
031:16:02 Mattingly: Okay. Stand by.
031:16:04 Borman: Okay. How about now, Houston?
031:16:10 Mattingly: Still no joy. [Pause.]
031:16:18 Mattingly: You don't have a lens cover on there, do you?
031:16:22 Borman: No, we checked that, as a matter of fact. [Pause.]
031:16:30 Borman: Anything?
031:16:32 Mattingly: Still no joy. [Long pause.]
031:16:56 Borman: How about now?
031:16:57 Mattingly: Still no joy. [Pause
Mattingly (continued): There is a picture
Mattingly (continued): We have a picture. Okay. It is a little difficult to see what we have.
031:17:17 Borman: That's the Earth, but it is not the telephoto lens, unfortunately. It is just a regular inside lens.
031:17:23 Mattingly: Okay. It is coming in as a real blight - a real bright blob on the screen. It is hard to tell what we are looking at.
031:17:31 Borman: You are looking through some haze on the windows too, unfortunately.
031:17:37 Lovell: And the Earth is very bright, besides
031:17:41 Mattingly: Okay. We got the Earth in about the center of the screen and a little bit low, and it looked like there were some objects that moved across it - the screen at the same time. Do you have any comment on those?
031:17:54 Borman: That's some water - some water ice coming off the vent nozzle.
031:17:59 Mattingly: Roger. [Pause.]
031:18:05 Borman: How does it look now?
031:18:06 Mattingly: Still the same thing; it is - the target is extremely bright, and it is very difficult to make out what we are looking at.
031:18:16 Borman: It is unfortunate that we do not have - we can't make the other lens work here. I don't know what the problem is
031:18:24 Mattingly: Okay. Apollo 8, would you verify that the ALC is on?
031:18:33 Borman: We have tried it both ways.
031:18:35 Mattingly: Oh, okay; thank you. What we are getting now is a good picture.
031:18:39 Borman: Say again. [Pause.]
031:18:44 Mattingly: Okay. That's a - that's a real good picture. That is the best one that we have had. And how about going ahead and just leaving your pictures inside until we can think some more of what we can do to adjust for that light?
031:18:58 Borman: Roger. [Pause.] Jim, what are you doing here? [Pause.] Jim is fixing dessert. He is making up a bag of chocolate pudding. You can see it come floating by. Bill is coming up from the lower equipment bay. [Long pause.]
Borman (continued): It is unfortunate that this telephoto lens doesn't work. Show them the lens that's the culprit here, Jim. This lens doesn't seem to be working; I can't understand why we're not - perhaps it's a problem of light transmission through it
031:19:56 Borman: This transmission is coming to you approximately halfway between the Moon and the Earth. We have been 31 hours and about 20 minutes into flight. We have about less than 40 hours left to go to the Moon. You can see Bill's got his toothbrush here. He's been brushing his teeth regularly. To demonstrate how things float around in zero g. It looks like he plays for the Astros, the way he tries to catch that thing. [Pause.] I certainly wish that we could show you the Earth. It is a beautiful, beautiful view, with predominantly blue background and just huge covers of white clouds, particularly one very strong vortex up near the terminator. Very, very beautiful. Perhaps we'll get some assistance from the people on the ground and be able to deter - to determine why this other lens is not transmitting properly.
031:21:11 Anders:Houston, did you get any light at all coming through that telephoto lens?
031:21:18 Mattingly: Apollo 8, we were getting what you were showing us on your normal lens, and I don't think we got anything on the telephoto. We are working on this now. One of the problems seems to be that it is a low light level lens; we're afraid that you might burn it out pointing it at something too bright
031:21:40 Borman: Well, the Earth is very, very bright. There is nothing in the lens you can burn out. The camera still seems to be working. We can give you a lumens reading of the Earth right now if you like.
031:21:54 Mattingly: Hey, Frank, how about a couple of words on your health for the wide world
031:22:03 Borman: Well, we are all in very good shape. Jim is busy working preparing lunch. Bill is playing cameraman right now, and I am about to take a light reading on the Earth. We all feel fine. It was a very exciting ride on that big Saturn, but it worked perfectly, and we're looking forward now, of course, for the day after tomorrow when we will be just 60 miles away from the Moon.
031:22:33 Mattingly: Roger. You all look great on candid TV [Pause.]
031:22:44 Borman: Okay. I just got a reading on the Earth, Houston. It is 320. The Earth is showing 320 lumens now. [Pause.]
Borman (continued): If you get a close-up of Jim Lovell, Bill, you can let everyone see he has already outdistanced us in the beard race. Jim has got quite a beard going already. [Pause.]
031:23:28 Lovell: Happy birthday, Mother. [Long pause.]
031:23:49 Borman: Okay. Jim is going to take a shot of us from the Lower Equipment Bay, and then we have to get back to our Passive Thermal Control in the barbecue mode so that we don't get one side of the spacecraft too hot for too long at a time. So we will be signing off here, and looking forward to seeing you all again shortly.
031:24:10 Mattingly: Roger.
031:24:13 Borman: Goodbye from Apollo 8.
031:24:17 Mattingly: Thank you. That's a good show.
We have had our picture cut off now after that television transmission. Total duration of some 20 minutes. During that TV transmission we got some very enthusiastic comments from the crew on the view from some 120,000 miles [220,000 km] from Earth. Borman described the Earth [as] very beautiful, looking blue, covered with white clouds. He also reported that all three crewmen at this point are in very good shape and all feel fine. At 31 hours, 24 minutes into the mission, this is Apollo Control.
031:24:24 Borman: I hope we can get that other lens fixed or some reading on it.
031:24:31 Mattingly: Roger. We are going to work on that one. The one that is sensitive to light is the lens that you were just using. You want to be careful about pointing that at some bright object.
031:24:43 Borman: Roger. We are starting PTC again.
031:24:45 Anders: I believe that's only if it hasn't been used for quite a while, Ken
031:40:04 Mattingly: Apollo 8, Houston.
031:40:08 Borman: Go ahead Houston, Apollo 8.
031:40:10 Mattingly: Okay, I've got a few items for you I'd like to clear up and then we'll let you alone for a while. The first thing is we would like for you to confirm that your spotmeter had an ASA setting of 100.
031:40:27 Borman: That is confirmed.
031:40:30 Mattingly: Okay, we thank you. That's one of the first questions that came to mind. We are ready for a cryo fan cycle at any time and use your normal procedures
031:40:47 Borman: Okay.
031:40:49 Mattingly: Alright. You can anticipate a fuel cell purge at 35 hours, and we ought to be through with battery A charging somewhere after 34 hours; and looks like you'll have just about a full battery there. And we will give you a call on the exact time to cut it off. We would like to get some confirmation from you on the chlorine procedures. Did you get some in last night or not? Just a quick summary of how much sleep you got on Lovell and Anders?
031:41:26 Borman: Okay. We got the chlorine in and the water has been chlorinated and just a minute I will check with them on their sleep.
031:41:40 Mattingly: I am sorry I didn't copy that sleep.
031:41:44 Borman: Say again, Ken.
031:41:46 Mattingly: I am sorry I didn't copy your last, Frank.
031:41:50 Borman: I was asking you to say to say what you said [sic]. Jim had about 4 hours sleep, and Bill had about 3 hours sleep.
031:42:07 Mattingly: Okay. Thank you very much.
031:42:12 Borman: We feel pretty good today. We would like to see, in looking over the Flight Plan - perhaps we ought to put the rest periods a little bit shorter and more frequent. It seems it might work out better. We got all out of kilter on it yesterday. We are sort of trying to get back in a normal cycle
031:42:32 Mattingly: Okay. We will look into that. [Pause.]
031:42:44 Borman: You all are doing good work. Keep it up.
031:42:46 Mattingly: Okay. Thank you. Looks like the only other thing we have left over is a comm check and if we can work that in without interrupting your present schedule we would like to.
031:42:58 Borman: Okay. Right now we are stopping for a break, but we will go ahead and do that. What does it involve?
031:43:06 Mattingly: Okay. We will need the High Gain Antenna, and there should be no comm loss during this mode. [Pause.]
031:43:22 Borman: Okay. Ken. I think we are going to lose the High Gain here shortly. Why don't we pick it up next time it comes around?
031:43:27 Mattingly: Real fine.
031:43:31 Borman: Remember, the most important part of the trip occurs in two days when we start back. So you all get better rested too.
031:43:40 Mattingly: We'll do that.
031:43:41 Mattingly: Affirmative, Apollo 8
031:52:41 Borman: Houston, we're starting the H2 fan now.
031:52:51 Mattingly: Roger, thank you
031:54:48 Borman: Houston, you just wanted 2 minutes cycling on those fans don't you? Two minutes each?
031:55:04 Mattingly: That's affirmative, Apollo 8.
031:55:08 Borman: Roger
At this time it is quiet. We have had no further communications with the crew. We expect that it will remain quiet for the next hour or two. At the present time, Apollo 8 is at an altitude of 123,768 nautical miles [229,218 km], and our current velocity reading here at Mission Control is 4,568 feet per second [1,392 m/s]. I believe this is in conflict with a figure given earlier on the velocity in our previous announcement. I recall it being reported at about 4,400 feet per second. I would like to point that the spacecraft is continuing to decelerate and the reference to 4,400 feet per second in a previous announcement would be incorrect. The current read - as I said 4,568 feet per second on the velocity. At 31 hours, 57 minutes into the mission; this is Apollo Control.
032:06:07 Borman: Houston, Apollo 8 on High Gain. Stand by for your communications check.
032:06:12 Mattingly: Okay, standing by
032:11:26 Borman: Apollo 8, Houston.
032:11:31 Borman: Go ahead Houston, Apollo 8.
032:11:33 Mattingly: Okay. Apollo 8. Looks like we're going to have to put this comm test off because of some tracking requirements. We can do it in about an hour if this will not interfere with your present operations too much. It'll take maybe 15 to 20 minutes, and it will involve some conversation on the part of the people onboard the spacecraft. So if that's going to interfere with your sleeping and all, why go ahead and we'll defer to that and we'll pick these requirements up at another time. And, I've got a score here, looks like Baltimore 21 to nothing.
032:12:16 Borman: Who were they playing? [Pause.]
032:12:26 Mattingly: How about Minnesota.
032:12:30 Borman: That's from that other league.
032:12:33 Lovell: How did last year's Army-Navy game come out?
This is Apollo Control at 32 hours, 14 minutes into the flight now. Apollo 8 is currently at an altitude of 124,506 nautical miles [230,585 km], traveling at a speed of 4,546 feet per second [1,386 m/s]. And we are in touch with the spacecraft at this time. We'll pick up communication and follow it along as it develops.
This is Apollo Control, we don't appear to have any more conversation developing with the spacecraft. [A] check with the Flight Dynamics Officer down here in Mission Control Center indicate that the spacecraft will continue to decelerate until about 55 hours, 38 minutes Ground Elapsed Time. At that point, our estimate is that it will come into the Moon's sphere of influence or perhaps more accurately the Moon's gravitational attraction will become the dominant force acting on the spacecraft, and the spacecraft will begin to accelerate again. At this point its altitude will be about 176,000 nautical miles [326,000 km]. It will be about 30,000 nautical miles [56,000 km] from the Moon. At 32 hours, 20 minutes into the flight; this is Apollo Control.
032:22:47 Anders: Houston, Apollo 8. Over.
032:22:49 Mattingly: Go ahead, Apollo 8.
032:22:53 Anders: Roger. We've stirred up all the cryos. Could you give me your quantities, please?
032:23:00 Mattingly: Okay. Stand by.
032:23:04 Anders: Roger. Be advised the CMP just hit the hay for a while, and the LMP will go down in a little while
032:23:12 Mattingly: Okay. And our guys down here are watching [the] High Gain Antenna pointing program, so anytime you're not using the DSKY for anything else, they'd like to watch it for a couple of cycles, so if you would leave that Noun 51 on the display it will help a lot down here
032:23:31 Anders: Okay. Why don't you give us Reacq[uire] angles, and we'll try that for the next time.
032:23:44 Mattingly: Okay. [Long pause.]

032:24:37 Mattingly: Apollo 8, are you ready to copy some cryo quantities?
032:24:45 Anders: I'm ready. How about O2 first.
032:24:47 Mattingly: Okay. O2 tank 1, I show 88.1 percent.
032:24:55 Anders: Okay. Could you give it to me in pounds, please?
032:25:02 Mattingly: Okay. You'll have to stand by while we convert that.
032:25:05 Anders: Thank you. [Pause.]
032:25:15 Anders: That's okay, Gene [means Ken], go ahead, I'll take the percent.
032:25:19 Mattingly: Okay. We will try and get the pounds for you, too, Bill. Tank 1, oxygen 88.1.
032:25:29 Anders: What time is that for?
032:25:30 Mattingly: This is present.
032:25:34 Anders: 32:30, okay.
032:25:38 Mattingly: Okay, I've got 32:35. And O2...
032:25:45 Anders: In weight, not percentage
032:25:46 Mattingly: Okay, O2 tank 1, 88.1; O2 tank 2, 87.37.
032:26:14 Anders: Is that 0.37 or 0.36?
032:26:17 Mattingly: 0.37.
032:26:22 Anders: Roger, 2. Got it
032:26:23 Mattingly: Okay, H2 tank 1, 75.97. Tank 2, 78.06. Over.
032:26:50 Anders: Okay, thank you very much. It looks good.
032:26:52 Mattingly: Okay, thank you
032:40:03 Mattingly: Apollo 8, Houston.
032:40:07 Borman: Go ahead, Houston, Apollo 8.
032:40:10 Mattingly: Okay. I've got a couple of things we need from you. I would like to get a battery C voltage. I would like to check a battery manifold pressure. Your High Gain...
032:40:25 Borman: Battery C is 37 volts.
032:40:28 Mattingly: Understand 37 volts on battery C. Is that affirm?
032:40:32 Borman: 3, 7.
032:40:34 Mattingly: Okay, thank you. And if you can get to the battery manifold pressure, like to read that one.
032:40:42 Borman: 0.6 volts
032:40:44 Mattingly: Alright understand 0.6 volts. The angles you asked for on the High Gain Antenna are pitch, minus 45; and yaw, 90. [Long pause.]
032:41:43 Borman: Okay. Houston, this is Apollo 8. I'm going to just go into High Gain now, and we're about ready to pick you up [garble] works on Reacq
032:41:50 Mattingly: Okay, and I have a scanning telescope star visibility item for you to pick up, when you're ready to copy that.
032:42:06 Borman: Roger, we'll get that on High Gain when we get back to you.
032:42:10 Mattingly: Okay, thank you.
032:42:11 Borman: We'll come back on High Gain.
032:42:12 Mattingly: Roger. [Pause.]
032:42:23 Borman: That's not fair, we're there already
032:42:28 Mattingly: That's pretty good acquisition, huh?
032:42:34 Borman: You guys are reading the DSKY. Go ahead Houston.
032:42:40 Mattingly: Okay, Apollo 8. Maybe we ought to try that one again next time, and the scanning telescope star visibility is scheduled for a 34:10 in the Flight Plan, and it'll be star number 31. The angles are roll, 184.7; pitch, 23.4; yaw, 14.3; shaft and trunnion zero. Over
032:43:28 Borman: Understand; star 31; roll, 184.7; pitch, 23.4; yaw, 14.3; and star shaft and trunnion at zero.
032:43:38 Mattingly: That's affirm, and that's copy star 31.
032:43:45 Borman: That's Roger, 31.
032:43:47 Mattingly: Okay, thank you. [Long pause.]
032:44:18 Borman: Houston, Apollo 8.
032:44:20 Mattingly: Go ahead.
032:44:24 Anders: The LMP would like to take a Seconal and hit the hay. [Pause.]
032:44:36 Mattingly: Okay. That's a Go.
032:44:41 Anders: Okay, thank you. [Pause.]
032:44:45 Anders: And that [garbled]
This is Apollo Control at 40 - rather 32 hours, 45 minutes. At the present time the spacecraft is at an altitude of 125,723 nautical miles [232,838 km], traveling at a speed now of 4,590 feet per second [1,399 m/s]. We've been in coversation with the crew for the last couple of minutes. At the present time Lunar Module Pilot Bill Anders and Command Module Pilot Jim Lovell are attempting to get a little bit of sleep. Anders requested a few moments ago that he be given a go ahead to take a Seconal tablet. This is one of the short acting sleeping pills carried aboard the spacecraft, And the medics have given him the go ahead to take the Seconal tablet. We'll ... stand by for further conversation with the crew.
032:50:06 Mattingly: Apollo 8, Houston.
032:50:10 Borman: Go ahead, Houston.
032:50:12 Mattingly: Okay. We'd like to go ahead and get into this comm check here, on the last of this High Gain period. If you're ready to go on it, I'll read you some switches
032:50:27 Borman: Stand by. We're ready. Go ahead.
032:50:29 Mattingly: Okay. Number 1. S-band Normal, Mode, Voice, to Voice.
032:50:43 Borman: Go ahead - keep going.
032:50:44 Mattingly: Uptelemetry, Data to Data. [Long pause.]
032:51:08 Borman: Normal, Mode, Voice, to Voice. Uptelemetry Data, to Data.
032:51:12 Mattingly: Okay, Uptelemetry Command, to Normal.
032:51:17 Borman: Normal.
032:51:18 Mattingly: High Gain Antenna, Track, Auto.
032:51:25 Borman: Roger. Going Auto.
032:51:27 Mattingly: High Gain Antenna, Beamwidth, to Narrow.
032:51:30 Borman: Beamwidth, Narrow.
032:51:33 Mattingly: Okay, this will be our baseline data check. This will be a full uplink voice with ranging and full downlink
032:57:53 Mattingly: Apollo 8, Houston. We are going to have to delay the comm check again
033:01:09 Borman: Houston, Apollo 8. How do you read?
033:01:13 Mattingly: Apollo 8, Houston. Did you call?
033:01:18 Borman: Roger. We lost you for a while there. Are you reading us there now?
033:01:20 Mattingly: Loud and clear now.
033:01:24 Borman: Okay. Thank you. So are we. [Pause.]
033:01:36 Mattingly: Okay, Apollo 8. Do you want to try that Auto, Reacq? 33 plus 24 looks like a good time and the angles are the same. And the late ball scores is 24 to 14..
033:01:48 Borman: [Garbled.]
033:01:51 Mattingly: Alright.
033:01:53 Borman: Say it again.
033:01:54 Mattingly: I say a late ball score there is...
033:01:55 Borman: [Garble] the ball score?
033:01:56 Mattingly: 2, 4 to 1, 4.
033:02:02 Borman: Baltimore over the Vikings?
033:02:05 Mattingly: Affirm
033:05:56 Borman: Houston, Apollo 8.
033:05:58 Mattingly: Go ahead, Apollo 8.
033:06:02 Borman: We have reached the scan limit on the High Gain. What do you want us to do about it now? [Long pause.]
033:06:39 Mattingly: Apollo 8, what we would like to do with these angles is to set it in Auto Reacq over on panel 2, and it is under the Tracking for the High Gain Antenna, and it'll - the lower position will say Reacq, and on the position dials we would like to set pitch to minus 45 and the yaw to 90.
033:07:08 Borman: Pitch, minus 45; yaw, 90.
033:07:10 Mattingly: Okay. Stand by one.
033:07:15 Borman: Roger. If we could leave it in Reacq if you want to use the High Gain, it would keep from waking us up every rev
033:10:32 Mattingly: Apollo 8, Houston. I think we may have gotten off on a tangent. These pitch and yaw angles that we called up to you for the High Gain Antenna were in response to Bill's request to know what positions we could put on there for a - for the Auto Reacq position. The constraint still remains if we don't want to be on an Omni antenna at the same time. We are in the Auto Reacq position; we should be in one or the other. So you can use that information if you want to try it out. Otherwise, the procedures you've been using all along will be just fine. Over
This is Apollo Control at 33 hours, 13 minutes. At the present time we are involved in a series of communications checks with the spacecraft. We will ... continue to monitor live.
033:15:41 Mattingly: Apollo 8, Houston. I am transmitting in the blind right now. Our downlink isn't working so well; I'm just going ahead on an uplink
AS08-16-2604 - Earth at approximately 226,000 km (based on photo analysis) at about 033:20 GET, and using the 80-mm lens. South is to the lower left and the Americas run up the terminator. The planet was evidently imaged through one of the fogged windows.
033:20:00 Borman: Houston, do you read? Apollo 8.
033:20:03 Mattingly: Apollo 8, read you weak but clear now.
033:20:08 Borman: Roger. Thank you.
033:20:10 Mattingly: Okay. Looks like we had a growl problem there.
033:20:18 Borman: Roger
033:33:31 Mattingly: Apollo 8, Houston.
033:33:34 Borman: Go ahead.
033:33:38 Mattingly: Okay. Looks like we're...
033:33:39 Borman: Go ahead, Houston. Apollo 8.
033:33:40 Mattingly: ...Looks like we're in a good attitude to try this High Gain Antenna on the comm check one more time. I believe you're still on an Omni. Is that correct?
033:33:52 Borman: Roger.
033:33:55 Mattingly: Okay. If we could try the High Gain and maybe we can get started on this comm check. I'd also like to verify that you've got the LMP and the CMP trying to get some sleep here, and we could use an oral temp from you, too.
033:34:16 Borman: Roger. My temperature is 97.5 [degrees Fahrenheit].
033:34:20 Mattingly: Okay. Thank you.
033:34:24 Borman: That's what it was this morning when I felt badly.
033:34:26 Mattingly: Alright; thank you. [Long pause.]
033:35:24 Borman: Do you want me to go to Omni now, Ken?
033:35:26 Mattingly: I'd like for you to go to High Gain.
033:35:28 Borman: High Gain?
033:35:29 Mattingly: Yes, sir.
033:35:33 Borman: High Gain. [Pause.]
033:35:40 Borman: This is Apollo 8 on High Gain.
033:35:44 Mattingly: Roger. Reading you kind of weak now, but we're gonna take a look at it. [Long pause.]
033:36:24 Borman: Houston, Apollo 8 on High Gain.
033:36:27 Mattingly: Okay. I'm reading you loud with just a little background noise.
033:36:33 Borman: Roger
This is Apollo Control at 33 hours, 38 minutes. Spacecraft, at this time, is 128,179 nautical miles [237,387 km] from Earth and our velocity is 4,434 feet per second [1,351 m/s]. We're still involved from time to time with the communications checks with the spacecraft. One of those is in progress at this time and we'll pick up ... and continue to follow along.
033:39:24 Mattingly: Apollo 8, Houston. We're not getting a good lock. I wonder if we could try making sure that we're in Auto on the track, and that we're in narrow beamwidth?
033:39:39 Borman: Standby. [Long pause.]
033:40:00 Borman: How's that, Houston?
033:40:04 Mattingly: Okay. That works real good
033:42:07 Mattingly: Apollo 8, this is Houston. What we're doing right now is collecting baseline data, and we'll be in this mode for another couple of minutes and then we'll be moving out to the second signal.
033:43:55 Mattingly: Apollo 8, Houston. How do you read? [No answer.]
033:44:22 Mattingly: Apollo 8, Houston.
033:44:27 Borman: Houston, Apollo 8. Read you five-by.
033:44:30 Mattingly: Okay. We are [garble] we have some ground problems, and we're reading you weak but clear. We're ready to start into our test. We're going to be changing our modes so you'll probably hear a burst of noise as we make the change. This will be a noise that sounds like an S-band onlock. However, your AEC leader will lock that off. This is due to the loss of modulation on the uplink. There will be about 2 minutes, and during this time, you will hear one burst of noise. [Long pause.]
033:45:39 Mattingly: Apollo 8, Houston. Voice check. Over. [No answer.]
033:45:57 Mattingly: Apollo 8, Houston. Ready to check. [No answer.]
033:46:20 Mattingly: Apollo 8, Houston. [No answer.]
033:46:38 Mattingly: Apollo 8, Houston.
033:46:43 Anders: Go ahead, Houston.
033:46:48 Mattingly: Apollo 8, this is Houston. Do you read?
033:46:53 Anders: That's affirmative.
033:46:54 Mattingly: Okay. Thank you. Were you reading all along? We just - This is the first time we've heard you call back.
033:47:02 Anders: We've been reading you; we're trying to hold the noise down so we can get some sleep.
033:47:09 Mattingly: Roger. We'll be through with this in just a minute, I think.
033:47:13 Anders: Roger. I will answer you, but I'll try to do it quietly.
033:47:18 Mattingly: Okay, Bill. [Long pause.]
033:47:45 Mattingly: Okay, Apollo 8. The next portion of our test is like we did yesterday; We'll be changing the uplink modes to uplink command and ranging with no upvoice. We'll be in this mode for approximately 2½ minutes and send two test messages. During this time, we will not have uplink. We are going to this mode at time 33:48:30, and we'll be back in this configuration at 33:50:00. Over.
033:50:59 Mattingly: Apollo 8, Houston. Radio check.
033:51:05 Anders: Loud and clear, Houston.
033:51:07 Mattingly: Okay, fine. How about telemetry inputs PCM [Pulse Code Modulation] switch to Low [bit rate], please? [Pause.]
033:51:17 Anders: They're in Low [bit rate], Houston. [Pause.]
033:51:24 Mattingly: Roger
033:52:53 Mattingly: Apollo 8, we've completed the third test; we're going into the final test now. PCM switch to High, please. [Long pause.]
033:54:01 Mattingly: Apollo 8, Houston. We're going to switch uplink to the upvoice backup for about 2 minutes, and may take a few seconds to link the transition. And we'll be back up at 33:56 in our normal mode to place the uptelemetry data switch to upvoice backup at this time. Over.
033:54:28 Anders: Roger
033:55:54 Mattingly: Apollo 8, Houston on backup voice.
033:56:00 Anders: Loud and clear, Houston.
033:56:02 Mattingly: Okay, fine; thank you. [Long pause.]
033:56:21 Mattingly: Apollo 8, let's go back uptelemetry data switch to Data. [Long pause.]
033:57:12 Mattingly: Apollo 8, Houston. [No answer.]
033:57:29 Mattingly: Apollo 8, Houston. [No answer.
033:58:56 Mattingly: Stand by; guess we've got 85-foot site voice back now; the noise went away.
033:59:02 Mattingly: Apollo 8, Houston. [Pause.]
033:59:10 Anders: Go ahead, Houston. [No answer.]
033:59:17 Anders: Go ahead, Houston.
033:59:19 Mattingly: Okay, Apollo 8. That completes our comm test. Thanks for your cooperation. And I've got a change here to Nav sightings that will come up at 32:20 [means 34:20]. And we want to change your star a little bit there. Are you ready to copy?
033:59:38 Anders: Ready to copy.
033:59:40 Mattingly: Okay.
033:59:41 Anders: Ready to copy.
033:59:43 Mattingly: Okay, Apollo 8. We would like to change the Nav sighting as follows: we would like to use star 26, that is, two-six; we would like to make it Earth-near horizon for two sets, two sets. Then we would like to take star 16 Earth-far horizon, one set. If star 26 Earth-near horizon is not possible, star 16 Earth-far horizon, one set, and star 22 Earth-far horizon, one set. Over.
034:00:36 Borman: Roger, Houston. Be advised the CMP is asleep [garble] putting those off for a while.
034:00:45 Mattingly: Okay. Stand by. [Long pause.]
034:01:34 Mattingly: Apollo 8, okay; we can put this off. What we will probably need from you is some kind of an estimate of when you think somebody will be available to work on it, and we are working on how much lead time we need now. [Pause.]
034:01:56 Anders: Stand by [garble].
034:01:58 Mattingly: Roger. [Pause.]
034:02:08 Borman: Houston, why don't you figure the CMP will sleep another couple of hours, then the LMP, and then the CDR up to about 43 hours equally. Over.
034:02:20 Mattingly: Okay.
034:02:25 Borman: Then we will start off with the CMP again at about 44
034:06:58 Mattingly: Apollo 8, Houston.
034:07:03 Borman: Go ahead, Houston.
034:07:05 Mattingly: Okay. We can put off this Nav sighting. It was scheduled here at 34:20, and we can put it off, judging from your comments about sleeping, we would like to get it as soon as we can, and right now, our plans are to slide it 2 hours. We will do the P52 by sliding it back to the same thing since it is associated with the P23. So if that's a convenient time for you, why we will plan on that
034:07:38 Borman: We are doing the P52 now. Do you want us to continue?
034:07:43 Mattingly: Well, as far as we are concerned, that isn't going to help us any. We will have to do it over again anyhow
034:07:54 Borman: Okay. And what time do you want to do it?
034:07:57 Mattingly: Well, if you think Jim's going to be up in a couple of hours, why, that will slide us 2 hours to 36:20.
034:08:08 Borman: Okay. We will go ahead and make another one there and pick it up then if that's okay.
034:08:12 Mattingly: Okay. That will be real fine. Thank you.
034:08:17 Borman: What we are going to try to do is get back on the sleep cycle to those sleep periods just prior to LOI [Lunar Orbit Insertion] by taking shorter cycles for each man.
034:08:29 Mattingly: Real fine
This is Apollo Control at 34 hours, 10 minutes. As you heard in that conversation with Commander Frank Borman, we will be rescheduling part of the Flight Plan activity in order to allow Jim Lovell to continue sleeping. That is the mid-course activity scheduled to occur between 34 and 35 hours in the Flight Plan. Current plans are to move that back about 2 hours. Do it after Lovell has had a chance to get some rest. Borman also advised that following Lovell's sleep period, Anders would attempt to get a few hours of rest [and] that he himself would try and get some rest. At 34 hours, 11 minutes into the flight, this is Apollo Control.
034:13:52 Borman: Houston, Apollo 8.
034:13:57 Mattingly: Apollo 8, go ahead.
034:14:01 Borman: How about giving us some Reacq angles, and we'll stay in Reacq.
034:14:05 Mattingly: Say again, please.
034:14:11 Borman: Could you give us some Reacq angles?
034:14:14 Mattingly: Wilco. [Pause.]
034:14:24 Borman: Say again. [Pause.]
034:14:29 Mattingly: Apollo 8, this is Houston. I hadn't said anything at that time. We're digging some angles out for you now. In reference to your earlier question about the sleep cycle juggling and so forth: we agree with your comment. We would like to get back on the flight plan as far as the sleep cycles and so forth are concerned by the time we get into lunar orbit. So we'd like for you to use your own judgment about the most efficient way to accommodate the sleep cycles and proportion it up among yourselves. We would like to have you keep us informed of who's doing what and what your plans are. We have the one P23 that we had slipped 2 hours. We'd like to get the other one in. We can also adjust the time for the other P23, if it's going to conflict - I guess that's two more P23s. We can adjust the time for those if you'll let us know what your forecast is for when Jim will be available to take some sightings. So the big message is that we'd like to work around whatever your desires are. If you'll let us know, we'll pick some stars and some angles and have them ready for you.
034:15:44 Borman: Okay, Houston. The CMP will be up at 36 hours. The LMP is going to sleep now, and he'll sleep through until 40 and then I'll stagger that in and try to go to sleep around 30 to 37 so that by the time we get to day 3 we'll all be back on the same direct sleep cycle.
034:16:12 Mattingly: Okay, real fine. Thank you. [Long pause.]
034:16:28 Mattingly: Apollo 8, Houston. Reacq angles look like minus 45 in pitch, plus 90 in yaw, and 34:23 for the time.
034:16:41 Borman: Roger. Copy. This is good using Reacq because it keeps the Caution and Warning from going off again
034:16:48 Mattingly: Roger. I understand that. Are you leaving the High Gain Antenna on after it swings over to the reset position?
034:17:04 Borman: Do you have any reason for us to use the High Gain Antenna?
034:17:10 Flight: EECOM, do you think we need that, really, very much.
034:17:13 Mattingly: Stand by.
034:17:15 Flight: Why can we just not use the High Gain Antenna for a while? Getting high bit rate on the Omnis. Okay, let's tell them that we'll just not worry about the Omni for a while. [Long pause.]
AS08-16-2605 - Earth at approximately 237,000 km (based on photo analysis) at about 034:20 GET, and using the 80-mm lens. South is to the lower left and the Americas run up the terminator. Baja California is visible at the top right.
034:18:30 Anders: Houston, this is the LMP. Before I hit the sack, could you give me a rundown on our systems the way you see them?
034:18:37 Mattingly: Okay, we'll put that together for you and we were just talking about the redundant ECS components check and we were going to put that off until everybody's had a chance to get some sleep. Trying to keep you from having to go to the left-hand couch.
034:18:54 Anders: Oh, that would be nice. I sent Lovell under the couch, though. I've got one man sleeping under the left couch here - right couch and one man sleeping on our right couch.
034:19:33 Mattingly: Okay. I understand you've got one under and one on the right couch.
034:19:39 Anders: Roger. That's affirmed.
034:19:41 Mattingly: Okay. And in reference to the Omni versus the High Gain, it looks like we can live with the Omni antennas here for several more hours, if you would like to delete the use of the High Gain.
034:20:10 Anders: Okay. Goodnight, Houston
034:20:16 Mattingly: Okay. Before you pitch your eyeballs there, we'd like to terminate the battery charge.
034:20:25 Anders: I knew you guys would get me.
034:20:27 Mattingly: Got you. [Pause.]
034:20:35 Anders: Okay. The battery A charge is terminated at 37.3 volts
034:20:41 Mattingly: Okay. Thank you. [Long pause.]
034:20:54 Anders: Standing by for your systems status.
034:20:56 Mattingly: Okay. We're pulling that together now.
034:21:01 Anders: How are the PU (Propellant Utilization) valve and SPS (Service Propulsion System) line temps looking?
034:21:05 Mattingly: Okay, I'll test that.
034:21:06 Anders: We just had [garble] I understand
This is Apollo Control at 34 hours, 23 minutes. And the past few minutes we've been in conversation with the spacecraft, Frank Borman and Lunar Module Pilot Bill Anders. And Bill advised that he was preparing to join Jim Lovell in getting a little bit of sleep, and Frank Borman advised that when one of the two wakes up a little later on, he'll try and get a few hours of rest, also. We'll ... continue to follow on any conversation live.
034:25:53 Anders: Systems look okay to you, Houston? [Pause.]
034:26:09 Mattingly: Okay, Apollo 8. All the systems - giving a quick look around the room - look real fine. You've got an RCS quad update on the quantity, so you have that information. The SPS oxidizer feed line temperature and the fuel temperature are both at 73 degrees. The cryo profile is running right on the line: Battery A - our calculations have 39.63 amp hours. Battery B, 37.94, and battery Charlie, 38.46. The comm continues to be running ahead of predictions in quality and circuit margins. Everything else looks like it's real fine.
034:27:06 Anders: Roger. Do you expect to have a low bit rate voice on the DSE off the Omnis at lunar distances?
034:27:23 Mattingly: That's negative on DSE of the Omnis. Not looking forward to that much improvement.
034:27:32 Anders: Roger. We need about a 30-foot dish, I figure, for that on the spacecraft.
034:27:47 Mattingly: Roger. It runs up the fuel required for PTC, though, Bill.
034:27:56 Anders: Roger
This is Apollo Control. There are no further communications with the spacecraft at this point, so we'll take the circuit down and stand by. At the present time, Apollo 8 is at an altitude of 130,368 nautical miles [241,441 km], and velocity is 4,370 feet per second [1,332 m/s]. This is Apollo Control at 34 hours, 33 minutes into the mission.
034:39:36 Mattingly: Apollo 8, Houston.
034:39:40 Borman: Go ahead, Houston, Apollo 8.
034:39:42 Mattingly: Okay. I know you're trying to be quiet, so I'll just read up some information to you. One of the things that we just turned up that might give you some confidence, if you lose [one] oxygen cryo tank now: you have 80 pounds remaining now at CM/SM sep. The limiting factor on single tank operation right now is the hydrogen tank which has a positive margin at CM/SM sep, assuming our standard profile gives you about 143 hours. So it looks like you are over the hill on those
Mattingly (continued): Notice that you're flying in the Rate 2 position for your BMAGs which is fine. Only make sure that you still were maintaining a PTC attitude. Looks like you're pretty close to it
034:40:41 Borman: Roger. We are flying PTC, and I was wondering why it was going out of the deadband; now I know. Thank you.
034:40:47 Mattingly: Okay. Thank you.
034:40:51 Borman: That's what happens when you let Anders fly. He's asleep so he can't defend himself.
034:41:12 Mattingly: Roger. But we've got it on tape though.
034:41:17 Borman: Good. They're both conked out; how about just filling me in on some news, and I'll keep quiet just to give me some words on what's going on in the world.
034:41:34 Mattingly: Okay. Give me a few minutes to collect some data, and we'll do that
This is Apollo Control at Houston at 34 hours, 57 minutes into the flight of Apollo 8. Here in Mission Control Center, Flight Director Milton Windler has just held what he termed a midshift briefing, bringing all the flight controllers here in the center up to date on the lastest developments as they stand in respect to the overall performance of the spacecraft and the status of the crew. In general, Flight Director Windler noted that the crew feels much better and they have been advised to set their own pace as you probably heard in the air-to-ground commentary between the ground and the crew. Lovell is currently sleeping, and he went to sleep at about 34 hours and plans to sleep through until about 36 hours GET. Bill Anders went to sleep about 20 minutes later, and we expect that he will be sleeping till about 40 hours Ground Elapsed Time. Frank Borman advised that he would like to try to get some sleep at about 37 hours Ground Elapsed Time, about 2 hours from now. And we expect that he will probably sleep 4 or 5 hours. All of the spacecraft systems look good at this time. We've also got a preliminary evaluation of the onboard TV performance this afternoon. And perhaps an explanation on the problems the crew experienced with the telephoto lens. The feeling at this time is that perhaps the automatic light control device on the camera was, in effect, fooled by the bright disk of the Earth in the dark background [of space], overcompensating and washing out the picture. We're running some tests to determine if this information was in fact was the case and it maybe possible to correct this on future TV transmission with the use of proper filters. We [will] stand by for any live conversations that develop in the meantime.
This is Apollo Control, we'll continue to stand by for any conversation with Frank Borman aboard the spacecraft. In the meantime, we would also like to perhaps clarify some figures we gave earlier concerning the point at which the spacecraft comes under the dominant influence of the Moon's gravity and begins accelerating toward the Moon. Now that figure we gave you was a time of - Ground Elapsed Time of 55 hours, 38 minutes. At that point the spacecraft velocity, this is inertial velocity, the - with respect to the Earth - is about 3,261 feet per second. And this occurs at an altitude from the Earth of 176,271 nautical miles [326,453 km]. At this point, the point at which the spacecraft passes into the lunar sphere of influence, gravitational influence, here in Mission Control Center will shift our reference point for measuring spacecraft velocity and will no longer be measuring it with respect to the Earth, but will begin measuring it with respect to the Moon. At this point, 55 hours, 38 minutes Ground Elapsed Time, the Earth-referenced velocity will be 3,261 feet per second [994 m/s], and by comparison in reference to the Moon it will be 3,980 [1,213 m/s] feet per second. To give you some indication of what continues to happen to the velocity then as we progress toward the Moon, the speed of the spacecraft with respect to the Earth will reach a minimum point some 65 hours into the flight when we're about 11,000 nautical miles [20,000 km] above the Moon. At this point, the velocity will be 3,083 feet per second [940 m/s] with respect to the Earth. With respect to the Moon, and this will be the figure that we'll be using in Mission Control Center, the velocity at that point, 65 hours into the flight, or 11,000 nautical miles from the Moon, the spacecraft velocity is projected to be about 4,353 feet per second [1,327 m/s] - 4,350 - and it will accelerate rapidly from that point for the next 4 hours until we reach the point of Lunar Orbit Insertion. That, nominally, is set to occur at this time at about 69 hours, 11 minutes. And for that 4-hour period of time, the velocity will increase from 4,350 feet per second to about 8,420 feet per second [2,566 m/s]. And then as we go into orbit about the Moon, that will reduce the velocity by slightly under 3,000 feet per second [900 m/s], taking it down to about 5,300 feet per second [1,600 m/s]. Coming back [to Earth] again, the same thing will apply in reverse. We'll follow the spacecraft velocity with respect to the Moon until the Earth becomes the dominant force - gravitational force acting upon the spacecraft. And then at that point we will transfer back to an Earth-referenced system. At the present time, Apollo 8 is at an altitude of 131,843 nautical miles [244,173 km], and we're traveling at a velocity of 4,327 feet per second [1,319 m/s]. At 35 hours, 5 minutes into the flight, this is Apollo Control.

035:13:30 Borman: Houston, Apollo 8. Houston, Apollo 8. How do you read?
035:13:38 Mattingly: Apollo 8, Houston. Read you loud and clear. We may have some uplink problems; transmitting in the blind, at this time. Over

035:16:23 Comm Tech: Hawaii Network GOSS Conference. How do you read?
035:16:32 Borman: Houston, How do you read? Apollo 8.
035:16:34 Mattingly: Apollo 8, I read you loud and clear. How me? [Long pause.]
035:17:31 Borman: Houston, Apollo 8. How do you read?
035:17:35 Mattingly: Apollo 8, Houston. Over. [Long pause.]

035:18:25 Mattingly: [Unheard by spacecraft] Apollo 8, Houston. Read you loud and clear.
035:18:37 Borman: Okay. Thank you, Hawaii. How do you read?
035:21:15 Network: Hawaii, Houston Network. Voice check on GOSS Conference
035:21:24 Mattingly: Apollo 8, Houston
This is Apollo Control Houston at 35 hours, 22 minutes into the flight. At the present time Apollo 8 is 132,542 nautical miles [245,467 km] from Earth, and our velocity is 4,307 feet per second [1,313 m/s]. At this time here in Mission Control Center we are working on a minor communications problem. We seem to have trouble getting the communications from the Control Center to Hawaii. We are reading the spacecraft loud and clear. No problem with communication across the 132,000 some odd miles between the spacecraft and Earth. The problem appears to be between Houston and Hawaii. Hawaii has been in touch with Frank Borman on the spacecraft and advised him that we are working on the problem at the present time and that we, as I said, do read the spacecraft loud and clear here in Houston. We are in the process at this time of switching to some of the back up routes that we have and checking those out. We expect to have communications restored shortly. This problem first appeared at about 35 hours, 10 minutes Ground Elapsed Time. As I say, we do expect to have it resolved shortly. We will continue to stand by and monitor and we will come back up after we have reestablished communications.
035:26:41 Comm Tech: Hawaii LOS [Loss of Signal]. Unable to find. [Long pause.]

035:28:16 Mattingly: Hawaii, Houston CapCom. I would like to have a voice check.
035:28:18 Comm Tech: Roger. I read you loud and clear
035:28:21 Mattingly: Okay. I'm reading you loud and clear. I understand you have contact with the spacecraft. Is that affirm?
035:28:26 Comm Tech: I have uplink voice to the spacecraft; the downlink is too low in the mud.
035:28:32 Mattingly: Okay. Understand that you have good uplink, but your downlink is in the mud. You don't have any way of copying it either, is that correct...
035:28:40 Borman: Houston, Apollo 8. [Garbled] again. How do you read?
035:28:41 Comm Tech: That is affirmative.
035:28:45 Mattingly: Okay, Hawaii, we can hear Apollo 8, calling down. Would you answer and tell them that we did copy that?
035:28:53 Comm Tech: Roger.
035:28:57 Comm Tech: Apollo 8, Hawaii M&O. Houston reports they copied your last.
035:29:03 Borman: Okay. Thank you.
035:29:08 Mattingly: Apollo 8, Houston. Over. [No answer.]
035:29:30 Network: Hawaii, Houston Network, GOSS Conference.
035:29:37 Network: Hawaii, Houston Network, GOSS Conference. You're Net 2.
035:29:41 Comm Tech: Houston Network, Hawaii.
035:29:43 Network: Roger. Did you copy the CapCom?
035:29:46 Comm Tech: Affirm. We copied the CapCom.
035:29:49 Network: Is he keying the transmitters out there?
035:29:58 Comm Tech: He did key it one time, Network.
035:30:01 Network: Okay. I'm going to ask him to call the spacecraft again, and I would like for you to give me a report if he does not key the transmitters.
035:30:11 Comm Tech: Roger. Network is our NET 1 now conferenced up...
035:30:15 Mattingly: Your NET 2 is conferenced to our GOSS Conference here.
035:30:21 Comm Tech: Roger. How about our GOSS Conference loop?
035:30:23 Mattingly: Your GOSS Conference loop is dead.
035:30:26 Comm Tech: Roger. We are Go for command. We were unable to transmit before.
035:30:31 Mattingly: Understand.
035:30:32 Comm Tech: We transmitted to the spacecraft as per CapCom and they acknowledged our transmission.
035:30:39 Mattingly: Apollo 8. Houston.
035:30:43 Borman: Go ahead, Houston. Apollo 8.
035:30:45 Mattingly: Okay. We got back together again. You're loud and clear. We've been reading you. We have a problem down here on the ground getting our signal from MCC out to remote site.
035:31:01 Borman: Roger. Understand.
035:31:02 Mattingly: Apollo 8. Houston. I've got a ball score for you. It was Oakland 41, Kansas City 6 is the final score. That's 41 to 6, Oakland. We're trying to get some news releases over here for you. I suspect we're going to find that the staged TV show was probably the biggest news of the day
035:31:20 Borman: I'm sorry that the TV lens broke down.
035:31:26 Mattingly: Well, we're working on that some more. I'm not sure that the whole thing is lost yet. It appears that our problem is one where the light intensity which is sensed by our light meter in there is picking up an average field which is much larger than the Earth, and so it's sensing a great deal of deep space environment, which is dark, and we're suspicious that this is probably opening up the lens aperture as wide as it will go, and then when you point the camera at the Earth while the Earth is only filling about 3 degrees of cone angle, whereas lens takes in 9. So it looks like you're probably just saturating the tube. Now we're playing around now with some...
035:33:14 Borman: We just lost you again, Houston.
035:33:16 Mattingly: Say again.
035:33:20 Borman: I just lost your last transmission; you were clipped.
035:33:24 Mattingly: Okay. Did you get any of my comments about the TV tube?
035:33:33 Borman: Roger. Got them.
035:33:35 Mattingly: Okay. What I - what we've got in mind here is that we are looking at some of the lenses you have on board for cameras, and we are going to see if one of them can possibly be used to attenuate some of this light so that you will be able to take one of these pictures, and we are running some tests now, and we'll let you know about those. I also have a maneuver PAD that I need to read up to you whenever it's convenient
035:34:04 Borman: Let me get a pencil. Be fine right now.
035:34:07 Mattingly: Okay. [Long pause.]
035:34:19 Borman: Go ahead, Houston.
035:34:23 Mattingly: Okay. The first one I will give you is a TLI plus 44 maneuver PAD. I will start reading down the left-hand column. TLI plus 44; SPS/G&N; 62970; minus 1.62, plus 1.29; 046:56:04.31; plus 0019.7, plus all zeros, plus 6070.1; 180, 133, 001; November Alpha, plus 0020.3; 6070.1, 7:04, 60451; 12, 137.5, 34.9. Boresight star is Earth, down 03.7, right 2.2; plus 10.68, minus 165.00; 1285.6, 36118, 098:27:17. The GDC alignment stars: the primary star is Sirius, secondary Rigel; 010, 294, 320; no ullage, fast return P37 Delta-V, 8750. This goes to the Indian Ocean and requires a high-speed procedure, that is minus Mike Alpha, and that will refer to your checklist page November Charlie 1. Over
This is Apollo Control in Houston at 35 hours, 37 minutes. We have reestablished our communications from the ground up to the spacecraft directly from Houston, and preliminary assessment of the problem is that it originated at the Goddard Space Flight Center where all of communications are routed through on route to Houston. Apparently we blew a fuse at Goddard and our communications circuit between Goddard and Hawaii was down. We were able to receive the spacecraft communications loud and clear here in Houston, and we were able to relay information through the station at Hawaii through the maintenance and operations people at Hawaii to the spacecraft. The link between Houston and Hawaii was restored after about 20 minutes and we're now in conversation with the spacecraft. ...
035:38:14 Borman: Okay, Houston. How do you read?
035:38:16 Mattingly: Loud and clear.
035:38:23 Borman: TLI plus 44, SPS/G&N; 62970; minus 1.62, plus 1.29; 046:56:04.31; plus 0019.7, plus all zeros, plus 6070.1; 180, 133, 001; [HA omitted] plus 0020.3; plus 6070.1, 7:04, 60451; 12, 137.5, 34.9; Earth, down 03.7, right 2.2; plus 10.68, minus 165; 1285.6, 36118, 098:27:17; Sirius and Rigel. Hello, Houston. How do you read now?
035:40:13 Mattingly: Loud and clear.
035:40:17 Borman: Sirius and Rigel; 010, 294, 320; no ullage, fast return P37 Delta-V 8750, Indian Ocean minus MA, checklist NC 1.
035:40:36 Mattingly: That's affirmative, Apollo 8. And I have a flyby PAD for you, also.
035:40:46 Borman: Go ahead.
035:40:48 Mattingly: Okay. This flyby PAD is an update to one that we gave you yesterday so you might want to note that this is the second one. And it will be a flyby; SPS/G&N; 62970; minus 1.62, plus 1.29; 060:59:48.07; plus 0096.6, plus 0055.2, minus 0207.9; Roll, pitch, and yaw are all zeros; November Alpha, perigee height plus 0020.2; 0235.8, 0:22, 0228.1; 03, 040.7, 31.7; 013, up 04.7, right 3.9; plus 14.18, minus 165.05; 1290.4, 36160, 146:29:12. Primary star Sirius, secondary Rigel; 136, 310, 340; no ullage; requires realignment to preferred REFSMMAT. This burn will raise perilune to 550 miles. Over
035:44:11 Borman: Okay. Houston. The second flyby SPS/G&N. Are you with me?
035:44:15 Mattingly: Yes sir.
035:44:21 Borman: 62970; minus 1.62, plus 1.29; 060:59:48.07; plus 0096.6, plus 0055.2, minus 0207.9. Next three are all zeros; N/A, plus 0020.2; 0235.8, 0:22, 0228.1; 03, 040.7, 31.7; 013, up 04.7, right 3.9; plus 14.18, minus 165.05; plus 1290.4, plus 36160, 146:29:12. Sirius, Rigel; 136, 310, 340; none, requires realignment to preferred REFSMMAT. Pericynthion to 550 miles.
035:45:47 Mattingly: That's correct, Apollo 8.
035:45:52 Borman: Thank you
035:48:26 Borman: Houston, Apollo 8.
035:48:29 Mattingly: Go ahead, Apollo 8.
035:48:32 Borman: Okay. The CMP is now up. We'll proceed with the 52 option and start on the cislunar navigation.
035:48:43 Mattingly: Okay. Thank you, and we'll start looking for some star data
035:53:58 Mattingly: Apollo 8, Houston.
035:54:02 Borman: Go ahead, Houston. Apollo 8.
035:54:05 Mattingly: Okay. When you pick up your activities, I have a preferred alignment here that I want you to be in when you do your P52. And I'll have about four items to change on your timelines, so if you give me a call when you're ready for it.
035:54:23 Borman: We're ready right now. We were doing the P52. You want to hold off and go to a particular alignment, is that right?
035:54:32 Mattingly: Affirmative
035:54:33 Borman: Alright. I'm ready.
035:54:35 Mattingly: Okay. The attitude is pitch, 23.4; roll, 184.7; yaw, 14.3. And the reason we're doing the alignment in this attitude is, the next thing we'll be coming up with is the scanning telescope visibility test and that will be 70 degrees, Sun and Arcturus, with a shaft and trunnion of zero. And then we can go ahead with the P52 and then a trunnion bias followed by P23 with the same stars we read to you before.
035:55:24 Borman: Okay
036:00:32 Borman: Houston, Apollo 8. We're maneuvering to the angles you - you gave us.
036:00:35 Mattingly: Alright. Thank you
This is Apollo Control. We don't appear to have any more communications developing between the ground and the spacecraft at this time. During that previous conversation part of the information that was passed up to the crew from the ground were routine updates to the backup information that is carried onboard the spacecraft to allow the crew to return to Earth at various points in the flight should it become necessary, and should at that point not be able to get updated information from the ground. This includes returns at 25 hours after, rather 35 hours after Translunar Injection, another point at which we pass up this so called block data. That's for 44 hours after Translunar Injection. And the crew has also been updated with the information they would need if they elected not to go in orbit around the Moon, but rather to do a flyby. This type of information is passed up routinely at certain specified periods during flight. At 36 hours, 4 minutes into the mission, Apollo 8 is now at an altitude of 134,264 nautical miles [248,656 km] from Earth, and the velocity is 4,258 feet per second [1,298 m/s].
036:09:45 Borman: Houston, we've reached the preferred attitude, and we're proceeding with the P52.
036:09:49 Mattingly: Okay. Real fine, and I'll pass up some advice from your friendly flight surgeon. He says you're supposed to take one more Lomotil.
036:10:03 Borman: Okay. Everybody, or just me?
036:10:07 Mattingly: Just Frank.
036:10:10 Borman: Thank you
036:13:20 Lovell: Houston, the P52 is completed. We're ready for your other data.
036:13:28 Mattingly: Okay. Understand that you've done the P52. The next item on the Flight Plan should be a scanning telescope visibility test, and this is the same one that was on your Flight Plan previously at 34 hours and about 12 minutes, and we'll be checking that 70 degree Sun's on Arcturus. Following that, we need to make a trunnion bias check, and then we'll go into a P23, and I can read you those star numbers and sets if you don't have them from the last time I read them up
036:14:13 Lovell: Okay. Standby. [Pause.]
036:14:20 Lovell: Houston, Apollo 8.
036:14:22 Mattingly: Go ahead.
036:14:26 Lovell: Roger. With such good visibility - or such good communications, we'll just give you a verbal description without seeing the scanning telescope right now. Your angles for maneuver to Arcturus were quite good. I've got Arcturus centered in the scanning telescope. At this Sun angle, there is a shaft of light directly across the center of the scanning telescope and - band of light. It precludes seeing a lot of stars around us, and although I kept my eye glued to the telescope now for some time, it's very difficult to see any star patterns or anything. I couldn't recognize that with Arcturus unless I - the optics just drove me there. Now, because I'm near zero shaft and zero trunnion, I'm getting quite a bit of shaft movement. Every time the shaft moves, more particles leave the optics, and they're just as bright as the surrounding stars. And they mingle in the stars, and you can't tell star patterns or constellations. With this particular attitude, the shaft of light precludes any identification of constellations or individual stars
Okay. Copy that. Can you tell us something about the orientation of this band? You mentioned that last night also
- that you also had a band about 10 degrees wide that ran across. Is there an orientation that we can tie that to?
036:16:05 Lovell: I believe so, Ken. This band is parallel to the M-line [a horizontal line in the reticle], and I think it has something to do with the design of the optics, where we have that shaft or the rectangular entrance of the optics from the outside. At this particular Sun angle, it cuts right across. Now I noticed that both the Earth and the Sun do this to the scanning telescope. In the sextant, the same light band is there, although it covers the entire sextant's field of view. However, the magnification brings out the stars quite well, and it is possible to mark on it. But it's the identification of the stars with the scanning telescope that makes it very difficult. Now the attitude I found that the optics are best at are the attitudes which give the constellations Canis Major and Orion in the scanning telescope. At this, this particular attitude of the spacecraft, the band is gone; we're in a position whereby the Sun is behind us, and I can see quite a few stars. Now yesterday I could also, after getting dark-adapted, see quite a few stars around the constellation Cassiopeia which at first I couldn't. But right now this band precludes you see anything at all except Arcturus which, of course, I know we're aiming at right now.
036:17:34 Mattingly: Okay. Thank you very much. [Long pause.]
036:18:08 Borman: Ken, what stars did you want to use [for the navigation exercise]? Did you want to read them off?
036:18:12 Mattingly: Okay. First star will be 26, and we'll be making two sets of measurements, Earth near-horizon using star 26. Then we would like to have one set [interrupted by noise from spacecraft] - we'd like to have one set on star 16 [Procyon, Alpha Canis Minoris], that's 16, using the Earth far-horizon. If it turns out that star 26 [Alpha Virginis] Earth near-horizon is not possible, then we'd like to have star 16 on the Earth far-horizon for one set, and star 22 [Alpha Leonis], Earth far-horizon, one set. Over.
036:19:04 Borman: You want star 26, Earth near-horizon, two sets; star 16, Earth far-horizon, one set; and star 22, Earth far-horizon, one set.
036:19:18 Mattingly: Okay. That's star 22 is only in the event that 26 on the Earth's near horizon is not possible? Over.
036:19:27 Borman: We won't even do star 22 then unless we can't get 26 on the near horizon.
036:19:31 Mattingly: That's affirmative. [Long pause.]
036:20:25 Anders: Comm sure is good all of a sudden, isn't it?
036:20:28 Mattingly: Yeah, this is outstanding
This is Apollo Control, Houston, at 36 hours, 23 minutes into the flight. Apollo 8, at this time, is at a distance from the Earth of 134 rather 135,042 nautical miles [250,097 km], and the current velocity is 4,236 feet per second [1,291 m/s]. Jim Lovell, who had been asleep for what appears to have been about 2 hours, is now up and we've heard from him aboard the spacecraft. At the present time, Lovell is involved in some midcourse navigation using the onboard Guidance and Navigation system. ...
This is Apollo Control. It appears we will have no further communication with the crew for the moment anyway. Shortly we would expect that Frank Borman would attempt to get a few hours rest. He indicated earlier that as soon as either Lovell or Anders awoke that he would attempt to get several hours of sleep. At the present time, Apollo 8 is at an altitude of 135,442 nautical miles [250,838 km] and our velocity is 4,225 feet per second [1,288 m/s]. This is Apollo Control at 36 hours, 33 minutes into the flight.
036:50:52 Borman: Houston, Apollo 8.
036:50:54 Mattingly: Go ahead, Apollo 8.
036:50:57 Borman: Okay, we have completed two sets on 26 and one set on 16.
036:51:02 Mattingly: Rog. You're getting pretty speedy there.
036:51:08 Borman: Yeah, Jim - Jim is getting to know the optics.
036:51:11 Lovell: Are you receiving the data, Houston?
036:51:13 Mattingly: Affirmative.
036:51:16 Lovell: Okay.
036:51:19 Mattingly: Keeping you honest.
036:51:23 Lovell: Right. [Long pause.]
036:51:40 Mattingly: Okay, Apollo 8. We have looked at the data and it looks good and they feel like you can go back to PTC attitude anytime you're ready to. And if you can [interruption from spacecraft] - go ahead.
036:51:56 Borman: What attitude do you want to use? The same one?
036:52:00 Mattingly: That's affirmative.
036:52:04 Borman: Thank you.
036:52:05 Mattingly: Okay, if you can reach over Bill there and get to panel 3, I believe we would like to cycle the oxygen fans. And also like to get the Biomed switch over to CMP.
036:52:24 Borman: Okay.
036:52:27 Mattingly: If you have to bother Bill to do that, why, we can hold off on the cryo fans.
036:52:31 Borman: No, he moved. We already chased him under the seat. Okay, now you want just the oxygen fans on?
036:52:38 Mattingly: That's affirm. Turn one on for about 2 minutes and when we turn it off, then we will turn the next one on. We don't want to turn them on simultaneously though.
036:52:49 Borman: Yeah, I know that. I mean you don't want hydrogen though?
036:52:53 Mattingly: That's affirmative. Just the oxygen
036:54:12 Lovell: Houston, Apollo 8.
036:54:16 Mattingly: Go ahead.
036:54:20 Lovell: Ken, just to recap a little explanation here on your maneuver PAD, something which I'm really not knowledgeable about, the way it was presented to us, you mentioned fast return P37 Delta-V of 8750, just briefly clarify that, will you please?
036:54:42 Mattingly: Okay, stand by
This is Apollo Control at 36 hours, 55 minutes into the flight of Apollo 8. At the present time we are in communication with the spacecraft. Jim Lovell is the only one of the three crewmen who is awake at the present time. Indications at this time are that both Frank Borman and Bill Anders are resting. And here in Mission Control Center as well as onboard the spacecraft, activities have slowed down somewhat and it has become quite quiet here. At the present time, Lovell has just finished a series of star sightings for onboard navigation. And we are in the process of passing up some PAD data to the crew. ...
036:57:43 Borman: Ken, can you give us a little report on how our trajectory looks and the tracking is going and things like that?
036:57:50 Mattingly: Okay, sure will. I will put a summary together here.
036:57:55 Borman: And the pericynthion sign
036:57:57 Mattingly: Roger, we will get all that together for you in just a few minutes.
036:58:01 Borman: And we never did get the news.
036:58:05 Mattingly: You are the news.
036:58:09 Borman: Come off it, come off it. [Long pause.]
036:58:41 Borman: Okay, the fans have been cycled 2 minutes each and they are back off.
036:58:45 Mattingly: Okay, thank you very much
037:06:07 Anders: Houston, Apollo 8 is back in the PTC attitude, reads MHPTC.
037:06:12 Mattingly: Okay, thank you. And in reference to your question about the P37 Delta-V, 8750, that's the number that goes into the option at P37 for your minimum-time return. That gives you a target for the Indian Ocean. And in this case, we are going to have to use the high-speed procedures that were worked out for you to use the minus number for the major axis.
037:06:47 Lovell: Roger. Understand. I'm going to give that a try, Ken, in a run through. I tried it yesterday, I wasn't getting too much in the way of results. I will give it a try today.
037:07:02 Mattingly: Okay. And on the - your tracking that we have now, it still looks like the time we gave you last night for time of pericynthion is still good, 69 plus 10 and right now your flyby pericynthion altitude - 65.8 [nautical miles, 121.9 km]. Looks like the midcourse number 3 is going to be something less than 1 foot-per-second. And all trajectory parameters are just holding real fine.
037:07:36 Borman: That's the things we like to hear. We would like to keep those holding very much.
037:07:45 Mattingly: Rog
This is Apollo Control. There appears to be no further conversation with the crew at this time, so we will take the circuit down for the time being. At the present, the mission appears to be going very well. Right on the Flight Plan, in most cases, and our crewmen reported earlier that they were feeling much better. A short while ago, the medics advised Frank Borman to take one additional Lomotil tablet. This is a pill to reduce bowel activity. We've heard no word from the crewmen of any physical problems they're having and the feeling here on the ground is that their condition is improving. We're at a quiet period in the Flight Plan. Frank Borman had indicated earlier that he planned to get some sleep beginning at about 37 hours Ground Elapsed Time. We heard from him at the beginning of the last transmission and deduced from that that he had still not, at that time, gone to sleep. However, it has been quiet now for sometime so perhaps he is getting some rest, at this point. At the present time, Apollo 8 is 137,127 nautical miles [253,959 km] from Earth and is traveling at a speed of 4,178 feet per second [1,273 m/s]. At 37 hours, 14 minutes into the flight, this is Apollo Control.
037:21:00 Borman: Houston, Apollo 8.
037:21:04 Mattingly: Go ahead.
037:21:08 Borman: Roger. We're getting near - we're going to need to dump some urine overboard here. I wonder if that's going to foul your trajectory up. Or can we go ahead and do it?
037:21:18 Mattingly: No, that's okay. Something that is kind of interesting though is that the last time you had your water dump, they noticed a change in the trajectory tracking at the same time and when they got through correlating it, they found some fellow that thought he knew the characteristics of a nozzle and how much water you're dumping and his estimates of the effect on the trajectory seemed to coincide with the tracked results. So I guess you have to stay honest on those things.
037:21:51 Borman: Roger. Okay. We'll go ahead and dump it.
037:21:55 Mattingly: Okay
037:23:29 Lovell: Houston, Apollo 8.
037:23:31 Mattingly: Rog. Go ahead.
037:23:35 Lovell: You planning on using our computer any time in the near future, I thought I'd do a little P37
037:24:50 Mattingly: Apollo 8, Houston. You can go ahead and run that 37 and we're going to kind of watch that from the ground, too, and see how it works out. A couple of items that are just of general interest in the trajectory world. Looks like the uncertainty in position is about 12 miles. Your uncertainty in velocity is about a quarter of a foot per second. And the perigee [means pericynthion] altitude uncertainty is 5 miles
037:25:26 Lovell: Roger. Understand. Just for information, perhaps you read it out on the ground. I ran our pericynthion altitude determination using first of all, P21 with our star state vector that we navigated with, we have plus 84.7 [nautical] mile altitude and then we ran out your state vector that you updated with us the last time. We got 64.2 and then I ran P30, using our state vector and got 82.6 nautical miles. These are all plus.
037:26:06 Mattingly: That's good. [Long Pause.
037:26:14 Lovell: What I'm going to attempt to do on P37 is to input your Delta-V on your TLI plus 44 and use that 44 burn time. I notice that the entry velocity is a little high. I think we might not be able to do a normal P37, but I'll give it a try
037:26:35 Mattingly: Roger
037:27:36 Lovell: Houston. One more question then before I start. Did you notice on this last update PAD, this minus MA, NC-1. Was that referring to the P37 fast return or the nominal maneuver which you gave me?
037:27:52 Mattingly: Apollo 8, that's referring to the fast return procedures.
037:27:58 Lovell: Okay. Thank you
037:31:55 Lovell: Houston, Apollo 8.
037:31:57 Mattingly: Go ahead.
037:32:00 Lovell: Are you following my procedure [That is, are you watching the DSKY displays as Jim is running P37]?
037:32:02 Mattingly: That's affirmative.
037:32:06 Lovell: Okay. This happened yesterday, too. I'm trying to load the Delta-V you gave us in the maneuver TLI plus 44 in P37, but I keep getting an operator error every time I try to load zeros for the termination of the middle and corner [R2]. Do you know what I'm doing wrong in my procedure?
037:32:31 Mattingly: Okay. Stand by
037:35:24 Mattingly: Apollo 8, Houston.
037:35:28 Lovell: Okay, go ahead. I can take it
037:35:31 Mattingly: Okay, looks like the decimal point in R2 under Noun 60 is on the extreme right-hand side so the proper load will be 06070. Over
037:35:46 Lovell: Ah, so. Okay, fine. Thank you. [Pause.] I'll update my checklist. Don't know what I want to update it for. I can't read
This is Apollo Control, Houston at 37 hours, 42 minutes into the flight of Apollo 8. At this time, the spacecraft is 138,226 nautical miles [255,994 km] from the Earth and traveling at a speed of 4,148 feet per second [1,264 m/s]. It's continued to be relatively quiet here in Mission Control and the Flight Plan also shows relatively little activity onboard the spacecraft for the crewmen. Both Frank Borman and Bill Anders are scheduled to be sleeping at this time. The crew are following the ground advice that was passed up earlier from Mission Control Center that they pace themselves and set their own work/sleep cycle to fit in with their own feelings and they appear to be following that advice. ... We'll ... stand by for any live conversation with the spacecraft.
037:54:24 Mattingly: Apollo 8, Houston. We are about to hand over to another site so you may lose lock momentarily
037:54:36 Lovell: Roger, Houston. Did you receive the results of the P37?
037:54:40 Mattingly: Sure did. Looks pretty good here.
037:54:45 Lovell: I concur
037:57:14 Mattingly: Apollo 8; Houston through Honeysuckle. The [ground station] switch is completed.
037:57:19 Comm Tech: You are loud and clear.
037:57:21 Mattingly: Roger
037:58:23 Lovell: Houston. Apollo 8.
037:58:25 Mattingly: Go ahead.
037:58:28 Lovell: Another comment on the optics. We're in PTC right now. We're passing the - we have the - a roll of about 182; we're about in 226 pitch and 18 in yaw. I can rotate the shaft all the way around at this particular attitude, and I get this band of light at about 10 degrees either side of the M-line. It - it varies in intensity with the shaft position. However, it's there at this particular attitude
037:59:06 Mattingly: Okay. Thank you. [Long pause.]
037:59:32 Mattingly: Jim, we have just been looking at your marks with respect to accuracy and they figure they are within a couple of thousandths of a degree of the theoretical optimum. And I guess the integrator seems to bear that out
037:59:53 Lovell: Well, I hope they're enough to get us home if we have to use them.
037:59:57 Mattingly: Well, I am getting a lot of confidence in your ability to run that mystery show now.
038:00:06 Anders: Hey, Jim [means Ken]. We have to spend four more days up here with him. Will you take it easy. [Pause.] He is already talking about going back to MIT as a professor.
038:00:08 Mattingly: [Laughter.
This is Apollo Control, Houston at 38 hours, 6 minutes into the flight of Apollo 8. At the present time the spacecraft is 139,151 nautical miles [257,707 km] from Earth and traveling at a speed of 4,122 feet per second [1,256 m/s]. In the last few minutes we had a conversation with Jim Lovell aboard the spacecraft. Lovell gave us another of the periodic updates that he has been passing down on the optic system used in conjunction with the onboard guidance and navigation equipment. Lovell again noted, as he has in the past, that he is getting a band of light through the field of view of his scanning telescope. This is a multiple use device. One of the uses that the crew would make of it is to locate and identify a particular constellation that they would be looking at through the sextant which is a 28 power device, giving them much greater magnification. The sextant would be pointing at a particular star in a constellation. The use of the scanning telescope is to identify the constellation that the sextant star is located in and then confirm that they are in fact on the proper star. It has been our observation here on the ground that the crew has been able to carry out the required sighting maneuvers, but Lovell has on occasions remarked that there appears to be some light scattering back into the field of view of the scanning telescope and obscuring part of his visibility. We will ... stand by for any live communication with the spacecraft.
This is Apollo Control, Houston at 38 hours, 41 minutes into the flight of Apollo 8. We have had no communications with the crew in the past 20 minutes since our previous announcement. At the present time, Apollo 8 is in an altitude of 140,600 nautical miles [260,400 km], traveling at a speed of 4,083 feet per second [1,244 m/s]. We continue to have a very quiet period, both here in Mission Control Center and on the Flight Plan. We have gotten a call from the spacecraft and we will pick that up now.
038:41:37 Borman: Hello, Houston. How do you read Apollo 8?
038:41:40 Mattingly: Oh, loud and clear. [Pause.]
038:41:45 Mattingly: You sure do sound wide awake. [Long pause.]
038:42:34 Borman: Hello, Houston, Apollo 8. How do you read?
038:42:36 Mattingly: Apollo 8, Houston. Read you loud and clear. How me? [No answer.
038:44:05 Network: Honeysuckle network, GOSS Conference. How do you read?
038:44:07 Borman: Houston, this is Apollo 8. How do you read?
038:44:11 Mattingly: Loud and clear, Apollo 8. [Long pause.]
Dinn (presumed comm): Apollo 8, Honeysuckle.
038:44:53 Borman: Go ahead Honeysuckle. How do you read?
Dinn (presumed comm): Loud and clear. We have comm problems to Houston at the moment.
038:45:03 Borman: Well, I would like to say hello to all of you in Australia. How is everything down there?
Dinn (presumed comm): Fine, and how's everything up there?
038:45:18 Borman: Pretty good so far.
038:45:25 Borman: Thank you. [Pause.]
038:45:27 Network: Honeysuckle, Houston network, on GOSS Conference. How do you read?
038:45:33 Comm Tech: Houston network, this is Honeysuckle reading at 5, 5.
038:45:38 Network: Roger. [Pause.]
038:45:45 Mattingly: Apollo 8, Houston. [No answer.]
038:45:53 Mattingly: Apollo 8, Houston. [No answer.]
038:46:18 Mattingly: Apollo 8, Houston. Over. [No answer.]
This is Apollo Control. We are apparently having some problems with direct communication from Houston to the spacecraft. We are reading them loud and clear. But at the present time we are having to relay information through the Honeysuckle maintenance operation personnel to the spacecraft and we are checking into the lines between here and Honeysuckle, Australia to determine just where the problem lies.
038:47:16 Mattingly: Apollo 8, Houston.
038:47:21 Borman: Roger, just checking with you. Hey, if you all start having ground switching problems, how about having some site that has Comm come in and tell us about it. Will you please?
038:47:35 Mattingly: Roger. Apollo 8. That's what we have been trying to do. Some of our problem seems to be getting from here to that site.
038:47:42 Borman: Houston. Apollo 8. How do you read?
038:47:45 Mattingly: Apollo 8, Houston. Loud and clear. How me? [Long pause.]
038:47:59 Borman: Houston, Apollo 8.
038:48:03 Mattingly: Apollo 8, Houston. Read you loud and clear. [Long pause.]
038:48:36 Mattingly: Apollo 8, Houston.
038:48:40 Borman: Roger. Go ahead Houston. Apollo 8.
038:48:43 Mattingly: Roger. We read you loud and clear and copy your remarks about having our remote site talk to you. Some of our problem has been in going from MCC to the remote site. We will attempt to do that anytime we can.
038:49:01 Borman: That's right. Just tell them you are having problems.
038:49:04 Mattingly: Rog.
AS08-16-2606 - Earth at 244,000 km (a very approximate figure based on photo analysis) taken using the 80-mm lens. Comparison with Celestia indicates a time of exposure of approximately 39 hours GET. South is to the top and Australia has appeared around the limb on the right. The planet was imaged through one of the fogged windows.
This is Apollo Control. Having reestablished two-way communication with the spacecraft, it appears that we won't hear anymore from the crew at least for the time being. We did hear from Frank Borman at the time that indicates that he is no longer resting, at least is not asleep. Frank had indicated earlier that he would attempt to get some rest beginning in about 37 hours Ground Elapsed Time, and we heard from here they're at about 38 hours, 45 minutes into the flight. We do not have an evaluation as to what the problem was with the uplink. The problem appeared to lie between Houston and the site at Honeysuckle. We were able to relay messages from Honeysuckle to the spacecraft, but we were not able to talk directly with the spacecraft from Houston. That problem, as we timed here, began 38 hours, 42 minutes, and we had calm reestablished at about 38 hours, 48 minutes - about 6 minutes after the call was first put in. At the present time Apollo 8 is at an altitude of 141,197 nautical miles [261,496 km], and its velocity is 4,067 feet per second [1,240 m/s]. I believe CapCom Ken Mattingly is preparing to put in another call to the crew. We'll stand by briefly for that.
This is Apollo Control at Houston; 39 hours, 10 minutes into the flight of Apollo 8. We've had no further communications with the crew since our previous report, and we do have a preliminary report on the cause of our communication problem through Honeysuckle. And it appears that the problem was with a control monitor panel at the Honeysuckle, Australia site. The exact nature of the problem with this piece of electronic equipment is not known at this time. It is associated with the unified S-band system at Honeysuckle. The problem, as we said, occurred at about 38 hours, 42 minutes Ground Elapsed Time and was corrected some 6 minutes later. And its effect was to prevent direct communications from Houston to the spacecraft; it did not effect communications from the spacecraft to Houston. And we were able to relay information to the crew through the maintenance and operation people at Honeysuckle. At the present time here in Mission Control, we are going through a change in shift. Flight Director Glynn Lunney and his black team of flight controllers are coming to replace Milton Windler. Gerald Carr will be the Astronaut Capsule Communicator replacing Astronaut Tom Mattingly. And at the present time the shift going off is briefing the oncoming shift on activities during the shift that is concluding at this time. At the present time Apollo 8 is at an altitude of 141,777 nautical miles [262,570 km], and the velocity continuing to drop down slowly, now down to 4,052 feet per second [1,235 m/s]. At 39 hours, 12 minutes into the flight; this is Apollo Control.
