Going down to 127:11, cross out “Verify DSE ON.” Beneath that a ways, cross out “127:14:20, start visual observations of Fra Mauro.”
-
Vance Brand (CAPCOM)
-
Beneath that, cross out “Continue visual observations,” and cross out “Stop observations.” And beneath that, cross out “Photo target 56 on track f:8, 250, infinity, 5,” et cetera, to the end of that line. Cross out the “5.6” beneath that and the penned-in “E15.”
-
Vance Brand (CAPCOM)
-
Over in the margin, to the left of all that, make a comment: “Delete visual only.”
-
Vance Brand (CAPCOM)
-
Okay. That's still on page 30, on the left-hand side. In the time—in the margin at the left where you have times, just pen in beneath the “127:10” the following: “Delete visual only.” That's only a comment.
-
Vance Brand (CAPCOM)
-
About—on the left-hand side about almost halfway down beneath the “VERB 49, maneuver to TOPO target 54A,” make the comment “Target 54A is optional.”
-
Vance Brand (CAPCOM)
-
And, next, page 35, on the right-hand side. Everything from “Spacecraft control, CMC, AUTO, verify” on down should be given the comment “Zodiacal light photos optional.”
-
Vance Brand (CAPCOM)
-
And, well, where you have the block in the middle of the page that says—the small block that says “Zodiacal light photos,” just put “Optional” in that title, too.
-
Vance Brand (CAPCOM)
-
Okay. First a comment. In the middle of the page is where the zodiacal light stuff ends, just under VERB 48. And then, if you'll go down to the bottom of the page, cross out the line “Photo target 12 on track,” et cetera, and cross out the “E5” that is below that line.
-
Jim Lovell (CDR)
-
We have the CRYO PRESSURE light on now. The H2 has hit its lower bound, so do you want us to go back to AUTO on the H2 HEATER 1?
-
Vance Brand (CAPCOM)
-
They request that you leave that switch in the AUTO position until you go to bed tonight. Stand by. I mean in the ON position. I'll repeat that again. In the OFF position until you go to bed tonight for reasons that you have a 3-percent imbalance, and they'd like to get that more even. So, just before turning in, we'll change the switch to AUTO.
-
Jack Swigert (CMP)
-
Before we get away, would you ask FAO—something I didn't get briefed on—what the penned-in E5 and those letters and numbers mean?
-
Vance Brand (CAPCOM)
-
Okay, new subject. Like to break in to say that request you re-initialize the PTT—PTC. For some reason, it's gone up to 18 degrees in pitch and yaw both. We don't quite understand this. All we can think of is—start it again. Over.
-
Vance Brand (CAPCOM)
-
Okay. We are at the—the end of the changes in the solo book, and I have two pages of changes in the flight plan. Those are pages 3-122 and 3-125. While you're looking that up, we'll put Ken on to answer your question.
-
Vance Brand (CAPCOM)
-
Okay. Okay, about—at time 156:50 on the right—well, on the right-hand half of the page, there's a line which states “Visual target 16, south, 180 plus 1:11, Gassendi, f:15.” Request you cross out that line.
-
Vance Brand (CAPCOM)
-
That's all on 3-122. Next change is 3-125.

Vance Brand (CAPCOM)

Okay, starting from the top of the page, cross out the first five lines, which are “Set up camera for contamination and photography, Betelgeuse, CM4/EL/80,” et cetera, “MAG T,” et cetera, “Install window shades.”
-
Vance Brand (CAPCOM)
-
Okay, then jump down to just about 159:28. Cross out “Maneuver to contamination field photography attitude,” and all other lines below that through “Enable thrusters A3, C4, B3,” et cetera.
-
Jim Lovell (CDR)
-
Okay, so we start with “Maneuver to contamination field photography,” and we cross out everything down to and including “Enable thrusters A3, C4, B3, and D4.”
-
Vance Brand (CAPCOM)
-
That's correct. And those are all of the flight changes—flight plan changes we have. And Ken is coming on now and later sometime when we get PTC squared away, and it's convenient, I suppose you should read all these things back to make sure that we're squared away on them.
-
Jack Swigert (CMP)
-
Yes. I guess I didn't understand what the letter and the number was behind some of these photo targets.
-
Ken Mattingly
-
Yes, sir. That's the map. Each fold is lettered in the lower—or upper right-hand corner if you work your way from east to west and the charts are labeled D, E, and F and the solo stuff will all be the D and E, and they change with the plane change 1. That's the time they change the two maps.
-
Jack Swigert (CMP)
-
Okay. I'm back at the attitude here, and I'll wait for rates to damps and you let me know when we're stable again.
-
Vance Brand (CAPCOM)
-
Roger. Just a reminder you have to disable Charlie and Delta here as you've done in the past. Over.
-
Vance Brand (CAPCOM)
-
Okay. FIDO says he knew it all along. He's—he says he's been very concerned that you've been doing a lot of water dumping.
-
Vance Brand (CAPCOM)
-
It may be awhile before your rates are settled down. We're still observing fairly high rates and deadbanding. Over.
-
Vance Brand (CAPCOM)
-
Okay. We've got about three items. First one is, all of your P23 batch—two marks have been evaluated and—Hey, congratulations. Looks real good; they're very happy with it. You're down to 4 arc-minutes on the substellar-point aspect of it, and that's the first thing to mention. The second is, unless you see a need, I don't see any need for you to read back the information we gave you on the solo book and so forth. Do you concur?
-
Jack Swigert (CMP)
-
Roger. I think I got it. I remembered a lot of it, and so I think with what you gave me and what I remember, I'm pretty sure we got it right.
-
Vance Brand (CAPCOM)
-
Okay, and the third item, I was just about to call that your rates were stabilized to start the PTC, but it looks like they're jiggling around again from a dump, so we'll stand by some more.
-
Vance Brand (CAPCOM)
-
Yes. You really have to watch that pair, all right. By the way, we have a maneuver pad for you, a fly-by pad, whenever you're ready to copy.
-
Vance Brand (CAPCOM)
-
Okay, maneuver pad, purpose: fly-by, SPS/G&N; 63385; plus 0.97, minus 0.23; 072:24:33.08; plus 0212.7, minus 0141.7, minus 0254.8; 148, 316, 050; NA, plus 0022.5; 0360.9, 0:53, 0356.3; 33, 352.7, 15.0; NA, NA, NA. Starting with latitude, minus 23.26, minus 165.00; 1147.7, 36172; 166:54:02. Comments, GDC aline stars are 31, Arcturus; and 23, Denebola. R aline 288, pitch aline 205, yaw aline 034; ullage, none; other, burn is SPS docked. LM weight, 33499. Over.

Our pad as follows: fly-by, SPS/G&N; 63385; plus 0.97, minus 0.23; 072:24:33.08; plus 0212.7, minus 0141.7, minus 0254.8; 148, 316, 050; NA, plus 0022.5; 0360.9, 0:53, 0356.3; 33, 352.7, 15.0; NA, NA, NA; minus 23.26, minus 165.00; 1147.7, 36172; 166:54:02; set stars 31, 23; roll is 288, pitch 205, yaw 034; no ullage; SPS docked; and LM weight, 33499.
-
Vance Brand (CAPCOM)
-
Roger. That's correct. Want to verify under NOUN 81 that DELTA-VX is plus 02127. You cut out right there.
-
Vance Brand (CAPCOM)
-
Okay. And when the computer is available, request P00 and ACCEPT and we'll ship you your state vector.
-
Jack Swigert (CMP)
-
You know, somehow, everytime I do a set of P23s, you guys uplink me a state vector. I don't think I do too well.
-
Vance Brand (CAPCOM)
-
No. You know—you know how the FIDOs are. They like to load in their own data, no matter what.
-
Vance Brand (CAPCOM)
-
And as a matter of interest, understand that the downrange comparison between the MCC and the computer is within 35000 feet, and that's on the last sighting, which people think is pretty good.
-
Jack Swigert (CMP)
-
Okay. Maybe that gives us a little more confidence that if we had to do P23s on the way home, we'd make it.
-
Vance Brand (CAPCOM)
-
Just info on your PTC, Jim. It's looking very good. Just—excursions in pitch and yaw are very low.
-
Vance Brand (CAPCOM)
-
Well, a minute ago, he said that to tell you that he was pacified now after your past comments on his trajectory and so forth, and he hadn't seen any waste water dumps or anything and he's pretty happy.
-
Jack Swigert (CMP)
-
Okay. I just wondered if we're going to need any more midcourse.
Expand selection down Contract selection up -
Jack Swigert (CMP)
-
Okay. BAT C 37, PYRO BAT A 37, PYRO BAT B 37, RCS A 97 percent, B 97 percent, C 96 percent, D 97 percent.
-
Vance Brand (CAPCOM)
-
Jim, just an item for you and Fred to be thinking about in case you haven't been briefed on this, something that's now being talked about a little bit. These conservative people would like to have you read the SHe tank pressure when you go into the LM for the LM familiarization at 58 hours. If there's no midcourse-3, and it looks like there's a good chance that there will not be, why, they might want to move the LM familiarization up from 58 to 55 hours. Over.
-
Jim Lovell (CDR)
-
Okay. If we don't have a midcourse-3, then we'll probably move LM FAM up to 55 hours, in which case we'll go in there and read SHe tank pressure.
-
Vance Brand (CAPCOM)
-
Roger. Along with the other FAM stuff, and it's not certain that we want to do this, it's just being talked about, so this is just the information for you.
-
Fred Haise (LMP)
-
Oh, we just finished eating and cleaning up a bit afterwards. Jim's going around collecting debris off of all the inlet hoses. And, I guess you might say we're kind of thinking about getting ready to go to sleep.
