Vance Brand (CAPCOM)
-
Okay. Unanimous opinion is that you're right, and we'll scratch all of this Bennett Comet stuff on the way out, with the hope that conditions will be more favorable after TEI. Over.
-
Vance Brand (CAPCOM)
-
And Apollo 13, you're GO for PTC. Your rates are very low according to what we can read.
-
Vance Brand (CAPCOM)
-
Just something to think about. In about 30 minutes, we can generate the pads that we have yet to send up before the sleep period, so we could support an earlier sleep period if you so desired. And—but, it will take us 30 minutes to get that stuff. The other thing is any time you're ready to copy, I can read up the solo book changes. Over—And, also, two pages in the flight plan.
-
Jim Lovell (CDR)
-
Okay, Vance. We're about ready to copy the solo book changes and the flight plan changes, and whenever your pads are ready, we'll take those. And as far as moving up the sleep period, that's fine, but we'll—if we don't go to sleep right away, we'll use it to get out some of our lunar maps and study them.
-
Vance Brand (CAPCOM)
-
Okay. And we'll get busy getting those pads for you as soon as possible then, and I'll stand by on the copying bit.
-
Vance Brand (CAPCOM)
-
Okay. First, turn to page 12. On the right-hand side of the page, starting from the middle of the page down, everything under “Cycle 5 frames, Replace dark side or dark slide” should be deleted until you get to the very bottom of the page where you have “Acquisition MSFN OMNI D” and that should remain in. Also, leave in “Remove window shades,” which is about the third line down from where you start.
-
Jack Swigert (CMP)
-
Okay. Okay. Then from “Cycle 5 frames, Replace dark slide,” from there on down, delete.
-
Vance Brand (CAPCOM)
-
That's everything from there on down, with the exception of “Remove window shades” and at the bottom “Acquisition MSFN OMNI D.”
-
Vance Brand (CAPCOM)
-
And that includes in the margin to the left, the “DAP load” that's at the very start there and the “0.0507” and “plus 0500,” farther down.
-
Vance Brand (CAPCOM)
-
Okay, in the left margin, just below 105 hours GET, cross out the “0507” and the “plus 0500,” and below that, add in “DAP load” as follows: “10111 and 11111.”
-
Vance Brand (CAPCOM)
-
Okay. Now, next, at about 105:05, there's a “VERB 48.” That should be moved up to 105, and below that, the “VERB 49 maneuver” should be moved up, too.
-
Vance Brand (CAPCOM)
-
Page 14, right-hand side, near the bottom under “Orbital Science,” scratch out “Verify DSE ON,” and also delete “Visual target 3 on track 180 plus 19,” and cross out the penned-in “D5.”
-
Vance Brand (CAPCOM)
-
Next, page 15, left-hand column, or left-hand side, rather, near the bottom, where it says “Configure cameras and tape” and goes down through “Replace dark slide.” Just make the comment there, “Solar corona is optional.” Over.
-
Vance Brand (CAPCOM)
-
Okay, next page, 16. This is a continuation of the same solar-corona thing. On the right-hand side of the page, starting just above 107:40 with “VERB 49, maneuver to solar-corona attitude,” from there on down to 107:55 just beneath “Replace dark slide,” all of this is in an optional category. So you just might line off —
-
Vance Brand (CAPCOM)
-
— starting at 108:00 on the left-hand side, line out “Stop ORB rate at ORB science attitude.” At—Line out in the left-hand column the DAP load of “10101” and “11111.” Going down to 108:10, add in the following: “Stop ORB rate at track attitude,” and, in parentheses, “0, 353, 0.” In the left-hand —
-
Vance Brand (CAPCOM)
-
Okay, in the left-hand column under 108:10, put in a DAP load in parentheses of “10101” and, under that, “11111.”
-
Vance Brand (CAPCOM)
-
Beneath that, scratch out “Spacecraft control dash CMC AUTO verify.” Scratch out the “VERB 79” and all in parentheses after that, like the “Minus 00507,” et cetera. And beneath that, scratch out “PRO to start pitch rate.” In parentheses, “0, 230 slash 018, 0.”
-
Vance Brand (CAPCOM)
-
Okay. Looking to the right, the LM attitude or rather the CSM attitude will be incorrect, so you can cross that off. And beneath the picture of the moon, cross out the—in parentheses, “108.19” and the “0 230/018, 0”
-
Vance Brand (CAPCOM)
-
On the right-hand half of the page, cross out the “Orbital science block,” and under that “Visual target 1 south of track TR.” And under that, the penned-in “D2/3/4.”
-
Vance Brand (CAPCOM)
-
And beneath that, cross out “VERB 49, maneuver to track attitude” by the “'C' 0, 353, 0” and the “HU,SCF.”
-
Vance Brand (CAPCOM)
-
Okay. The information beneath that starting with “Configure camera earthshine photos” down through “Replace dark slides” is optional. So just put in “Earthshine optional” as a comment there, and in the camera settings, in the block that has “f:2.8 125, infinity,” cross out the “125” and put in “one-eighth,” 1 slash 8, in other words.
-
Vance Brand (CAPCOM)
-
Okay. On the right-hand side, from the “VERB 49, maneuver to earthshine attitude,” down through everything up to “MSFN uplink,” this is optional. This is “Earthshine optional.”
-
Vance Brand (CAPCOM)
-
And once again, a camera-setting correction up near the top of that section that we called optional, where you have “bracket MIR f:0.9, 125,” cross out the “125” and put in “1 slash 60.” In other words, one-sixtieth. Over.
-
Vance Brand (CAPCOM)
-
That's correct. And further down at 109:50, where you have “Visual target 17,” et cetera, cross out that line and cross out the penned-in “D17.”
-
Vance Brand (CAPCOM)
-
Okay. At about 114:10, everything under “Altitude set equals 60 miles” should have the comment “Solar corona, optional,” and on that first line of that optional where it says “VERB 49, maneuver to solar corona and limb brightening attitude,” cross out “And limb brightening attitude.”
-
Vance Brand (CAPCOM)
-
Going further down to 114:16, cross out the “14 DAC 18 VHBW limb brightening” line and the line under that which is “BRKT, MIR,” et cetera.
-
Vance Brand (CAPCOM)
-
In the block where it says “Solar corona and limb brightening photos,” cross out “And limb brightening photos” and just put “Solar corona, optional.”
-
Vance Brand (CAPCOM)
-
Going a few lines below that where you see “DAC ON for 4 seconds at about 50 frame rate cover lens,” cross that out.
-
Vance Brand (CAPCOM)
-
And at the very bottom line on that half of the page should be crossed out which is “114:29:56, DAC OFF, SR.”
-
Vance Brand (CAPCOM)
-
On the right-hand side of page 25, where you have the title “Solar corona and limb brightening photography,” cross out “limb brightening photography.”
-
Vance Brand (CAPCOM)
-
And in the figure, where you have the “DAC LOS” line, which is parallel to the X-axis on the horizon, cross out “DAC LOS” parallel to X-axis on horizon.
-
Vance Brand (CAPCOM)
-
And cross out the bottom block on that half of the page which is “DAC magazine percent required 12 magazines, g,” et cetera.
-
Vance Brand (CAPCOM)
-
Okay. Cross out the top line on the right-hand side of that page, which is “DAC on for 4 seconds, 50 frame rate cover lens.” And cross out the block to the right of that and down, which has “Magazine percent.”
-
Vance Brand (CAPCOM)
-
Okay. On the left-hand side of page 28, at the very bottom, cross out “Photo target 5 north, frame f:5.6, 215, infinity,” et cetera. All of that line over to the vertical strip. And cross out the penned-in “E4” below that.
-
Vance Brand (CAPCOM)
-
Okay, and the next page, 29, right-hand side near the top, cross out “Photo target 13, north at 5.6, 250,” et cetera, all of that line. And cross out beneath that the penned-in “E5 slash 6.”
-
Vance Brand (CAPCOM)
-
At the top at 127:01, cross out “Visual target 9 on track, 180 degrees, plus 0.47,” and cross out the penned-in “E11” beneath that.
-
Vance Brand (CAPCOM)
-
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.”
Expand selection down Contract selection up -
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)
-
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.
