Jerry Carr (CAPCOM): Roger. Got some information for you on this PTC that we'll be going to right after this next P23 exercise. We'd like you this time to try the nose north attitude, that's pitch of 180, and a yaw of 315, and also we'd like to give another look at this mode free type of PTC and we think maybe we'll get a little bit of spin stabilization if we try it at 0.3 degrees per second on the roll rate rather than 0.1. So if you figure on doing that at 124:30 we'll see what kind of information we can get out of it.
05 03 23 14
Frank Borman (CDR): Okay. You know what I think of that, don't you? I'll be happy to do it, but I think it's playing games.
05 03 23 22
Jerry Carr (CAPCOM): Roger, Frank, you're burning right now 1.4 pounds per hour with attitude hold in pitch and yaw. We're kind of interested to see if 0.3 degrees per second will reduce your RCS usage due to spin stabilization.
05 03 23 40
Frank Borman (CDR): Yes, I know. I predict that it will not.
05 03 23 45
Jerry Carr (CAPCOM): Okay.
05 03 23 48
Frank Borman (CDR): Jerry, I'm a little concerned about the temperature. We're getting kind of warm in here, and also the evaporator outlet temperature is up around 45 degrees. Do you have any trend that we're getting less efficient operation of the radiators?
05 03 24 15
Jerry Carr (CAPCOM): Frank, EECOM says everything looks nominal down here. You might try a change in your cabin temperature heat exchanger there.
05 03 24 26
Frank Borman (CDR): No, we don't have the fans on, but what we have done is put up a window shade. That seems to help it. We've been getting a lot more sun in the cabin this way.
05 03 24 35
Jerry Carr (CAPCOM): Roger. We'll keep a sharp eye on things and keep you posted.
05 03 24 40
Frank Borman (CDR): Roger. I don't mind playing games because, you guys have been very nice in the five and a half days. If you want to play games in the next half hour, we'll play.
05 03 24 48
Jerry Carr (CAPCOM): Roger, Frank.
05 03 25 09
Frank Borman (CDR): Jim is trying this set with the eye relief optics so we can give you some information on that.
05 03 25 15
Jerry Carr (CAPCOM): Okay.
05 03 25 49
Frank Borman (CDR): I think it would be very difficult to extrapolate anything that you are getting out of this bit business to a LM-command module combination, because the spacecraft handles quit a bit different just with the change of fuel load, including the difference in drifting off and roll.
05 03 26 07
Jerry Carr (CAPCOM): Roger, Frank. We just got finished discussing that, too. We agree with your point of view on that one. I think this is more of a curiosity thing than anything at all.
05 03 26 18
Jim Lovell (CMP): I think it's fine. No sweat. We don't have anything else to do here for about another 10 hours.
05 03 26 20
Jerry Carr (CAPCOM): Okay.
05 03 26 27
Jim Lovell (CMP): Jerry, what I'm kind of curious about is the fuel usage. Now with P23 and what we were doing, we have a lot more fuel.
05 03 26 57
Jerry Carr (CAPCOM): Jim, we'll take a look at that fuel usage bit. Right now, the trend looks like it is getting better as we would expect with a lighter weight.
05 03 27 10
Jerry Carr (CAPCOM): We'll try to get a little more definitive for you here.
05 03 27 14
Jim Lovell (CMP): Okay.
05 03 27 15
Frank Borman (CDR): We really—we shouldn't complain about the fuel usage on that SPS engine though, because we're sure getting a lot of miles per gallon out of it.
05 03 27 27
Jerry Carr (CAPCOM): Roger, Frank. Frank, we'll enter you in the Shell road test on that.
05 03 27 29
Frank Borman (CDR): Yes, we don't have any TCP in it, or what is that, TCP? Yes. That's the problem. If we'd had that, we would have probably used only half the fuel.
05 03 27 47
Jerry Carr (CAPCOM): Oh, you mean Platformate?
05 03 27 50
Frank Borman (CDR): That's right, Platformate.
05 03 28 02
Frank Borman (CDR): If you will get the people to spread out one of those banners around the target area, we'll try to break it, you know, and coast through it.
05 03 28 11
Jerry Carr (CAPCOM): Okay. We'll call some of the paper companies and see if they can find a roll big enough.
05 03 28 17
Frank Borman (CDR): It won't take a big roll, just about 30 feet.
05 03 28 21
Jerry Carr (CAPCOM): Roger.
05 03 28 26
Jim Lovell (CMP): Onboard NAV.
05 03 28 36
Frank Borman (CDR): Tell the doctors that we put William to sleep.
05 03 28 41
Jerry Carr (CAPCOM): Roger. You won't leave any scars will you?
05 03 28 47
Frank Borman (CDR): No. No, he's got his tape recorder with him.
05 03 29 10
Frank Borman (CDR): Bill said to call Valerie and have her to rewind the tape recorder—his tape recorder at home.
05 03 30 55
Jerry Carr (CAPCOM): Apollo 8, Houston.
05 03 30 57
Frank Borman (CDR): Go ahead.
05 03 30 58
Jerry Carr (CAPCOM): I hate to tell you this, Frank, because Jim probably won't even be able to wear his COMM carrier anymore, but that last set of marks put your state vector right on top of the MSFN state vector.
05 03 31 10
Jim Lovell (CMP): Come off that, Jerry. Come on; you promised.
05 03 31 14
Jim Lovell (CMP): I'll get you that bottle of brandy when I get home, Jerry.
05 03 31 19
Frank Borman (CDR): Maybe we can get him to go to PROGRAM 01 again today, too.
05 03 31 24
Jerry Carr (CAPCOM): Roger. That sounds good.
05 03 32 04
Jerry Carr (CAPCOM): Apollo 8, Houston. Also, on the flight plan for 124:30, we would like for you to run an O₂ purge on the fuel cells.
05 03 32 17
Frank Borman (CDR): Okay.
05 03 33 24
Frank Borman (CDR): Hey, Jerry. We were going over the checklist on entry here, you know?
05 03 33 28
Jerry Carr (CAPCOM): Roger, Frank.
05 03 33 30
Frank Borman (CDR): I've got a question. Is John Harpold around?

05 03 33 40
Jerry Carr (CAPCOM): Roger. He is listening.
05 03 33 44
Frank Borman (CDR): John, I can't remember. Is the lift vector up head-down or —
05 03 33 59
Jim Lovell (CMP): Jerry, I'm beginning to worry up here.
05 03 34 03
Jerry Carr (CAPCOM): Roger. It depends on which way your nose is pointing.
05 03 34 08
Frank Borman (CDR): Touché.
05 03 34 16
Frank Borman (CDR): You might note for the people at MIT that the next series of stars will be shot by the master navigator with a space helmet on and long eye relief eyepieces.
05 03 34 32
Jerry Carr (CAPCOM): Roger. That ought to cut his speed down a little bit.
05 03 34 36
Frank Borman (CDR): Right.
05 03 35 25
Jerry Carr (CAPCOM): Frank, while you are talking about the entry checklist, this cold soak—have you decided exactly where you want to do it there prior to entry
05 03 35 37
Frank Borman (CDR): Well, I understood that EECOM talked that over with Bill, and we do it 1 hour prior to entry. We'll do it wherever you say is the best.
05 03 35 43
Jerry Carr (CAPCOM): Okay. One hour is fine. It's just a matter of finding time in the time line to do it.
05 03 35 50
Frank Borman (CDR): I think we can initiate it 1 hour before SEP.
05 03 35 53
Jerry Carr (CAPCOM): Okay. Fine. Sounds like a winner.
05 03 37 06
Jim Lovell (CMP): Really got all zeroes with that helmet on.
05 03 37 09
Jerry Carr (CAPCOM): Roger. We just noticed that.
05 03 37 32
Frank Borman (CDR): Jim's going to leave the helmet off now for the rest of them, I think; it gets a little anoxic in there. These helmets don't have face plates, and we have a difficult time breathing with that on.
05 03 37 44
Jerry Carr (CAPCOM): Roger.
05 04 02 26
Frank Borman (CDR): Okay. Jerry, that completes the P23. Did you have something else you want us to do now? You wanted to check on something from the last set.
05 04 02 37
Jerry Carr (CAPCOM): Roger, Frank. We need to get some numbers that we weren't able to copy down here. Stand by just one. Frank, on your first P23, we missed three marks on star number 2. We missed mark number 3 trunnion.
05 04 03 07
Frank Borman (CDR): Okay. Three trunnion is 05650.
05 04 03 11
Jerry Carr (CAPCOM): Okay, 05650. Then star number 1, mark 2. We need the trunnion on that one, too.
05 04 03 21
Frank Borman (CDR): 04216.
05 04 03 25
Jerry Carr (CAPCOM): And on star number 1, mark 3, the DELTA-R and DELTA-V.
05 04 03 31
Frank Borman (CDR): DELTA-R is 00006, DELTA-V 00001.
05 04 03 38
Jerry Carr (CAPCOM): Roger. Four balls 6 and four balls 1. Okay. Frank, your PTC attitude is pitch 180, yaw 315, and roll rate 0.3 degrees per second. The reason for wanting to point it north is not because we are concerned at all about any changes due to venting, there's been, as we can tell, no effects on your trajectory by venting. We just want to try out that direction on it.
05 04 04 16
Frank Borman (CDR): That's fine. We are going to stay in for about two more seconds while Jim takes the pictures through the sextant for the optics people.
05 04 04 24
Jerry Carr (CAPCOM): Okay, Frank. And then, also, we are looking for a fuel cell O₂ purge when you get a chance.
05 04 04 30
Frank Borman (CDR): That's right. At—I got the word now; it's supposed to be at 124:30.
05 04 04 37
Jerry Carr (CAPCOM): Right.
05 04 04 39
Frank Borman (CDR): Okay. We'll do it.
05 04 11 14
Jerry Carr (CAPCOM): Apollo 8, Houston.
05 04 11 17
Frank Borman (CDR): Go ahead.
05 04 11 18
Jerry Carr (CAPCOM): Roger. For your P37 that's coming up that you are going to run, use a midcourse 7 time of 144:46. Also just a little note here, the trajectory is looking so good, it looks like you can make the corridor without even making a midcourse 7.
05 04 11 37
Frank Borman (CDR): Roger. 144:46 for the P37.

05 04 11 44
Jerry Carr (CAPCOM): Affirmative.
05 04 11 47
Frank Borman (CDR): Thank you.
05 04 13 40
Jim Lovell (CMP): Jerry, this is Jim.
05 04 13 43
Jerry Carr (CAPCOM): Go ahead, Jim.
05 04 13 46
Jim Lovell (CMP): We are going to set this up for the normal PTC mode for a few minutes until Frank gets through with the—another step of the call.
05 04 14 01
Jerry Carr (CAPCOM): Roger, Jim. When the time is auspicious, would you shift the BIOMED switch over to left side?
05 04 14 09
Jim Lovell (CMP): I think we ought to shift it over right now.
05 04 14 12
Jerry Carr (CAPCOM): Okay. No, they say hold it up for a little while.
05 04 14 15
Jim Lovell (CMP): … so you can see, the same data that Dr. Berry got on me in Gemini VII is also good for Frank on Apollo 8.
05 04 14 33
Jerry Carr (CAPCOM): Roger. He heard that.
05 04 19 25
Jim Lovell (CMP): Houston, Apollo 8. —
05 04 19 28
Jerry Carr (CAPCOM): Apollo 8, Houston.
05 04 19 31
Jim Lovell (CMP): Do you see that PROGRAM ALARM we got when we went through P37, 1302?
05 04 19 35
Jerry Carr (CAPCOM): Affirmative.
05 04 19 39
Jim Lovell (CMP): I'll run through it again and see what happens here.
05 04 19 41
Jerry Carr (CAPCOM): Roger. We're monitoring.
05 04 21 33
Jerry Carr (CAPCOM): Apollo 8, Houston.
05 04 21 36
Jim Lovell (CMP): Go ahead.
05 04 21 37
Jerry Carr (CAPCOM): Looks like you loaded the wrong time in P37, You should load 144:46 for your midcourse time; looks like you loaded 146:46.
