CDR: Yes. One little problem we ought to discuss with you before we go on. It seems that somewhere along the way, the outer pane of glass on the tape meter has been shattered. I don't know whether you can get a picture of it on the TV or not; we'11 get A1 to try and zero in. But about 70 percent of the glass is gone. The inner pane of glass seems to be okay. There's no apparent damage to the tape meter itself. It's sitting on 520 and 482. But, I don't know whether you can see it or not, but I'11 trace the area which is missing with my finger here. And it looks like the pieces we found - I found one piece that's almost an inch in size, and there's some smaller ones around. We'11 try to pick it up with the tape, and then get the vacuum cleaner later on - to get it all up. So far that's the only obvious discrepancy we've found.
CC: Roger. Dave, we're reading you loud and clear.
CDR: - - ... you want to go back? Okay; back to LO bit rate. Let's try that.
LMP: Yes. Camera's configured, Dave.
LMP: Except for the MAG.
LMP: Okay; we're in LO bit rate. Houston, how do you read Falcon on low bit rate?
CC: Falcon, Houston is reading you loud and clear on LO bit rate.
LMP: Roger. We read you the same.
CDR: Okay; lets go back BIOMED, RIGHT and HI bit rate.
LMP: Okay. HI and RIGHT. Houston, this is Falcon on HI bit rate, with BIOMED, RIGHT. How do you read?
CC: Roger, Falcon. We're writing - we're reading you loud and clear.
LMP: We're reading you the same.
LMP: Houston, this is Falcon again. BIOMED, RIGHT and LO bit rate.
CC: Roger, Falcon. We're reading you loud and clear on BIOMED, RIGHT and LO bit rate.
CC: Endeavour, we're not reading Falcon at the present time, and we've had loss of signal.
CMP: Houston, Endeavour. Roger; understand. And wonder if you Just got that last piece on the TV there. It was a piece of gray tape with some glass on it that came out of the tape meter.
CC: We're getting a very good picture of it, thank you.
CC: Falcon, this is Houston. Reading you loud and clear. How us?
LMP: Houston, we caught the first part of your trans- mission, and then you were cut out.
CC: Roger. Falcon, this is Houston. How do you read us?
LMP: Okay, Houston. We're in PCM HIGH. How do you read?
CC: Roger. Houston is reading you loud and clear. And did I understand PCM HIGH?
LMP: That's affirm. 23/7 Tape
LMP: Houston, this is Falcon. Standing by for a voice and range check.
CC: Roger, Falcon. We're ready for step 8.
LMP: Houston, we're configured for step 8.
CC: Roger, Falcon. We're reading you loud and clear. How us?
LMP: ED VOLTAGE reading 37 on both.
CC: Roger, Falcon. We copy that.
CC: Falcon, this is Houston.
LMP: Go ahead Houston, Falcon.
CC: Roger. We'd like to tell you that the initial problem with and - with the S-band was a ground problem, and it looks as though all of the comm checks are GO. And, we would like to ask if our VHF uplink was okayl
CDR: Okay, VHF A and B both checked out, with Endeavour, loud and clear. And since we don't have anything other than the sequence camera to check out here, we're going to check that out and then powerdown and take care of the rest of the housekeeping without the power.
CC: Roger, Falcon.
CC: Be advised that we have - had an excellent TV show here, and that you can secure it, as you like. And I'd like to remind you that we have a - an update to the LM Contingency Checklist that we need to make before you leave - leave the LM.
CDR: Okay, we'11 take that over in the command module, Karl. We'11 go ahead and power the LM down now and clean up the housekeeping, and see you on the other side.
CC: Falcon, stand by. We're interested in the OPS checkout.
CDR: Roger. We can give you that from the command module.
CDR: We'11 do all the housekeeping. We'11 Just give you report from Endeavour.
CC: Falcon, that all sounds good, and only one other mat - matter, and that's the docking index angle as you go back through.
CDR: Roger. We checked that. It was plus .1.
CDR: Hey, Houston, correction. That's a minus .1.
CC: Correction received.
CDR: It's so close to zero it's hard to tell.
CMP: Okay, Karl. I'11 go ahead and secure the TV now.
CMP: Okay, Karl. I've got the OPS checkout numbers for you if you want them.
CC: Very good. Go ahead.
CMP: Okay. Commander's OPS had a source pressure of 5800, 5800, and a regulated pressure of 3.8. And the LMP's source pressure was 5800, and regulator pressure was 3.85.
CC: And, 15, when Jim has a couple of minutes, we'd like to ask a few questions about the high-gain antenna.
CMP: Okay; he's off the headset right now, Karl. I'11 get him as soon as I can.
CC: Okay. Tape24/1 APOLLO 15 AIR-TO-GROUnD VOICE TRANSCRIPTION
CMP: Hi, Karl. Hey, listen; we're start - going to start up PTC here pretty soon. Do you want to up- date which RCS Jets you want me to use?
CMP: Okay. I'11 go ahead and do the VERB 49 maneuver and start damping rates.
CC: Negative, Al. We want to stand by in this attitude.
CC: We - we are thinking real hard down here about your AC glitch and its possible connection to the loam of corem.
CC: Whenever Jim is available, we would be pleased to ask a couple of questions.
CMP: Roger, Karl. You have to stand by on that. He's finishing up over in the LM right now.
CC: Al, if you are looking for a Job, I could read you up a flyby pad.
CMP: Okay, Karl. Be a moment.
CMP: Okay, Houston; this is 15. Go ahead with the pad, Karl. SPS/G&N;
CC: Roger. Purpose is flyby, 66655; plus 1.24, minus 0.11; 07B:BO:56.80; plus 0257.2, plus 0230.9, minus 0312.9; BB1, 109, 079; NA, plus 0020.8; 0467.6, 1_.11, 0463.0; sextant star is 02, 148.5, 26.2; boresight star is NA; latitude, plus 1B.32, minus 174.02; 1098.7, B6170; 170:59:57. GDC aline stars, Vega and Deneb; 209; 009; B49. No ullage comments. The burn is SPS docked. Number 2, use onboard preferred REFBMMAT, because of yaw gimbal angle. Number 3, LM weight is 36220. And that's all.
CMP: Roger; understand. Purpose is flyby, that's SPS/ G&N; and pad's as follows: 66655; plus 1.24, minus 0.11; 073-30:56.80; plus 0257.2, plus 0230.9, minus 0314.9; 331, 109, 079; and the next is NA; and I missed a couple in there. Picking up that sextant star would be 02, 148.5, 26.4; boresight star is NA; latitude is plus 13.32, longitude, minus 174.04; 1098.7, 36170; 170:59:57. Vega and Deneb are set stars; with angles of 209; 009; and 349. No ullage. And the SPB docked burn, use a preferred REFSMMAT because of the yaw gimbal angle, and the LM weight is 33260.
CC: The LM weight is 36220.
CMP: Okay, Karl. Understand; 36220.
CC: That's correct. And down in NOUN 44, Hp is plus 0020.8; DELTA-VT, 0467.6, burn time, l:11, DELTA-Vc, 0463.0.
CMP: Roger, Karl; understand. HA is NA, Hp is plus 0020.8; DELTA-V T is 0467.6, with a burn time of l:11, DELTA-Vc, 0463.0.
CC: Roger. Tham's all correct.
LMP: Houston, this is - Endeavour.
LMP: Houston, this is Apollo 15. Over.
CC: 15, this is Houston. This is Houston; go ahead.
LMP: Yes, Karl, this is Jim. I'm back in and on comm. As far as that AC and main bus undervolt, I have not much more to add than what I said before. Do you have any other questions?
CC: Roger. Stand by Just about 30 seconds, and we'11 come up with a couple.
LMP: Go ahead, Karl.
CC: Jim, we've been doing a lot of thinking about that AC glitch down here, and - the coincidence of time - makes us guess that there is a connection with that power loss, but we don't see how. We'd like to start off with a couple of questions. The first one is, when you - reacquired on the high gain antenna, did you possibly notice that the high gain angles were different from what you'd set on the knobs?
LMP: Yes; as a matter of fact, they were.
LMP: I - I did nothing up here to reacquire on the - the high gain. It came back automatically.
CC: Okay; that's interesting information. Were there any talkbacks noted changing state at the time of the glitch?
LMP: No change that I noticed.
CC: Okay. Was anyone in the tunnel at the time of the glitch?
LMP: Say again about the tunnel, Karl.
CC: Was anyone in the tunnel at the time of the glitch?
LMP: Okay, Karl. A1 was in the tunnel, but there were no electrical connections being made at the time.
CC: Roger. I - I guess a follow up question then -- and you've probably answered it is, was there any unusual activity associated with the tunnel umbilicals?
LMP: Don't think so - we don't think so_ Karl, not at that time.
CC: Okay. And another question on this line is, what was and what is the position of the LM power 1 main B and 2 main B circuit breakers on panel 5?
CC: Okay. If you have some minutes to spare up there, we'd like to go through a cockpit check for open circuit breakers connected with main B and AC 2, on the theory that whatever happened might have blown a circuit breaker that wasn't obvious to you.
LMP: Okay. I'11 - I'11 do that now.
CC: We suggest - that - well, you know, this - figures 3-1 and 3-2 are a good guide to that for the nor- mally open circuit breakers.
LMP: I'11 check all circuit breakers.
CC: Jim, I've got the diagrams down here, if there's anything I can do to help you.
LMP: Okay; we'11 look around.
LMP: Karl, this is Jim.
LMP: Roger. On 226, under LIGHTING, NUMERICS/INTEGRAL, LEB AC 2 has been popped, or I believe it's popped. I would think it'd normally be closed now.
CC: Roger, Jim. We confirm that that is normally closed.
LMP: Okay; it looks like it might be the problem.
CC: 15, this is Houston. 24/5 Tape
CC: When you're through checking the circuit breakers, we have a little procedure we'd like to go through here as - as a further check.
LMP: Okay. Did you want me to continue checking? I figured after I - Stand by.
CC: Roger, Jim. We - we'd like to have a - a complete check there, and don't - don't reset that circuit breaker, incidentally.
LMP: Okay, Karl. I've checked all circuit breakers, and that's the .0nly one that seems to be out of configuration.
CC: Okay; very good. What we're going to do, Jim, is to drop the up-link and see what happens. And just to clarify the communications glitch that we had, the ground _tation lost the power amplifier, and we lost up-link to you. There was apparently no loss of down-link. So what we want to do now is to - is to drop the up-link and see if it creates the same glitches that - as you got on the AC bus that time. In view of your circuit breaker being out, we donlt think there's a connection, but we'd just like ta have this final confirmation. And - -
LMP: Okay; we're standing by.
CC: - - to start the procedure here, we'd like to just double check that you - that the dials for the HIGH GAIN ANTENNA are setting at PITCH, minus 30; YAW, 276.
LMP: Yes, that's correct.
CC: Roger. And verify that we have - -
LMP: YAW - YAW is really - -
CC: We - we'd like to have AUTO and NARROW.
LMP: YAW is - -
LMP: PITCH is minus 30, YAW is 270, and TRACK is AUTO.
CC: Roger, Jim. And what we're going to do now is to and drop up-link for 20 seconds, you are to read and record the high gain antenna dials and any changes that occur there. Then we'11 bring up the up-link; and, at that time, we want you to require - reacquire HIGH GAIN ANTENNA on - on AUTO, NARROW. Okay?
LMP: Okay. Right now the YAW indicator is reading about 280.
CC: What does your dial say?
LMP: The dial is 280. The thumbwheel is 270.
CC: That's okay. And are you ready for us to drop the up-link?
LMP: Go ahead. Yes, go ahead.
CC: Okay. We'11 be dropping - dropping the up-link for 20 seconds. Here we go.
CC: 15, this is Houston. How do you read?
CDR: This is 15. I read you loud and clear.
CC: Roger. Did you observe anything special up there?
CDR: Nothing other than the - the PITCH went to 0, and the YAW decreased Just very slightly. And, of course, when you reacquired, it went back to - PITCH went back to 30.
CC: 15, this is Houston. That's enough troubleshooting, and we' re ready to go to PTC now. And we' d like to have you use the A and D quads for damping. And use the B and D quads for spinup. And we'd like to confirm that we are using a spin rate of .375 this time.
LMP: We copied all that, Karl. A and D for damping, B and D for spinup. And .375 for the rate.
CC: Roger. Page ll3 APOLLO 15 AIR-TO-GROUND VOICE TRANSCRIPTION
CC: 15, this is Houston. Your rates look low enough to go into spinup, if all of your vents have been closed.
CDR: Okay, Karl. I think we got everything closed, and we'11 go ahead and spin her up.
CC: 15, could you please confirm that you're on OMNI Bravo.
CDR: That's affirm; Karl. We're on OMNI Bravo.
CC: 15, this is Houston. We have a read-out down here that A-1 Jet is on - could you confirm that? And if it is on, let's turn it off.
CMP: Roger, Houston; 15. Your read-out is correct and it's now o_f. Sorry, Karl, I overlooked that one.
CC: 15, this is Houston. Your spinup is looking very good to us, and when you have a couple of minutes to listen, we have a brief status report to send up to you.
CDR: Okay; go ahead, Houston. We're standing by.
CC: Okay. In regards to your range rate tape meter - That is normally sealed in a helium atmosphere at 15 psi, and with that outer glass broken, this seal is broken and the meter is now operating in 0 to 5 psi in an oxygen environment. We don't know that this has any effect on it, but Grumman is doing tests to show whether or not it's okay. Concerning the SPS - -
CC: Yes, go ahead.
CDR: I was Just going to say, it would be interesting to hear what they find out.
CC: Roger, we'11 let you w_ow. Concerning the SPS, we're still reviewing the LOI procedures that we'11 use, but it's probable that we'11 want to start automatically on bank B and bring on A 5 seconds later, using the circuit breaker, and then turning it off at 6 minutes and finishing up the burn on bank B. It's probable that the other burns, except for TEI, will be done on bank B only. Any comments on that?
CDR: No, that!s Just about what we were thinking too, Karl.
CC: Okay. In the LM, the batteries and the SHe look in perfect shape, and concerning the lighting circuit breaker problem, we're still getting in the data in down here, and we'11 review the situation with you tomorrow. We see no problem with the high gain antenna. And other than your - and other than your crew status report and your onboard read-out, that just about wraps up the evening. We'd still like to have your PRD read- outs, and I guess we have a battery charge in progress that will need to be cut off.
CDR: Okay, Karl; we'11 finish up the rest of the items here and bring you up to date on all the read-outs, and - Sorry about the PRDs, but since ... tonight.
CC: Okay. No problem on that. And I have a - I have the update to the LM Contingency Checklist, and if you want to take it this evening, I can give it to you; otherwise, it can be put off until tomorrow.
CDR: ... notes you have ... Contingency Checklist.
CC: 15, this is Houston. I heard you trying to come through but we were noisy Just then. Hold off Just a minute. 'Tape25/3
CDR: ... Houston, 15.
CC: Reading you better now; go ahead.
CC: 15, this is Houston. I'm reading you loud and clear.
CC: 15, this is Houston. How do you read me?
CDR: ... clear.
CC: Roger. Did I understand that you were ready for the LM Flight Plan - Contingency Checklist update?
CDR: Yes, I am, Karl.
CC: Roger. On page l-l, down under "Power Transfer and RCS Heater Activation."
CC: At the end of step 2, add the following line: "Circuit breaker 16, STABILIZATION/CONTROL, ASA, close. ?
CDR: Okay; I copy that.
CC: Roger. On page 1-7. Under "AGS Activation."
CC: Okay?
CDR: I was standing by.
CC: Add before 3tep l: "Verify ASA circuit breaker - has been closed for 10 minutes."
CDR: Roger. Understand before step l, "Verify ASA circuit breaker's been closed for 10 minutes."
CC: Roger. The next one is page 2-5.
CC: And on that circuit breaker configuration, in the second row down, put a black dot under the ASA circuit breaker.
CDR: Okay; I understand.
CC: And on page 2-13. Under "AGS Activation and Self Test," add before step l: "Verify ASA circuit breaker - has been closed for 10 minutes."
CDR: Okay; I copied all of that.
CC: Very good. That's all of the update.
CDR: Okay; thank you, Karl.
CC: 15, this is Houston. How are you enjoying dinner ?
CDR: It's Just fine, Karl.
CC: Great, glad to hear it. Hey, we'd like to ask a question about that glass breakage in the LM. Did it shatter into little bits or Just a few big hunks? How well do you think you got it cleaned up?
CDR: I think we probably got about - maybe 50, 60 percent of what was broken, and it was broken into - some pieces on the order of three-quarters to an inch and other little - millimeter-type pieces. Tape
CC: Okay. I guess that gives us a picture of the situation. We're somewhat concerned about that having drifted into equipment or - yes, into equipment.
CDR: Okay. Well we looked around and picked up what we could with tape, and we took the vacuum cleaner over and ran it for quite a while to try and pull up what we could.
CDR: We don't have any idea why it broke. It didn't look like there was anything in the ISA which could have done that to the - Just the face of that meter. The ISA had mostly soft equipment. It was pretty well padded.
CC: 15, this is Houston. We're ready to terminate the charge on BAT A now.
CDR: Roger. Terminate charge on BAT A.
CC: And incidentally, we see a - an off-nominal drain on BAT A, and we'd like to verify that the PITCH 1 and the YAW i circuit breakers on panel 8 are open. If not, we'd like to open them.
CDR: Okay. Stand by. Circuit breakers are verified open.
CC: Thank you. And, let's leave them open.
CC: 15, this is - 15, this is Houston. I want to correct a false impression I gave you. We don't see any off-nominal drain on battery A.
CDR: Alright, Fred. Thank you.
CDR: Okay; Houston, 15.
CDR: Okay. We have a presleep checklist when you're ready to copy.
CC: Roger, 15. Go ahead.
CDR: Okay. Crew status report, everybody's in good shape. No medication today. The onboard readouts: BAT C, 37; PYRO BAT A, 37.2; B, B7.2; RCS A, 90; B, 89; C, 91; and D, 89. The fans are being cycled now. The water has been chlorinated. All the valves are closed. We're getting ready to pump up the cabin. And we'11 give you a E-memory dump whenever you are ready.
CDR: And one more thing, we've - I've got the PRDs for you.
CC: Great. Go ahead.
CDR: Okay. CDR is 23020, the CMP is 5008, and the LMP is 8008,
CC: Thank you, Dave. And incidentally, if you'd like to get rid of that biomed harness, you can change off now_ you know?
CDR: Oh, that should work, right now.
CC: 15, this is Houston. We're ready for the E-memory dump.
CDR: Roger. And here it comes.
CC: And, Dave, a - we - our telemetry says that the optics power is still on, and I'd like to remind you to turn it off.
CDR: Hey, I thought we Just got that off.
CDR: Well, Karl, does your telemetry tell you it's on or off now? Page ll9
CC: They were Just telling me that - hey, it was off about the time that I called you.

CC: No, I agree; he should be aware of it. I'11 stand by.
CMP: Joe, Jim's awake here. Ready to listen.
CC: Okay, Apollo 15. This is your friendly news reporter with the morning news. Apparently the Houston Post reported, yesterday, that the Falcon's checkout went smoothly, and the mission is proceed- ing on schedule. The inside pages show drawings of how you will deploy the lunar roving vehicle. They didn't tell us anything I think we don't already know so I won't go into the details of the drawings. In national news - Now, we may be use - losing communications now; I'11 stand by a minute.

Moving right along, now, the national news, Secretary of Labor Hodgson has asked the United Transportation Union and the rail industry to put their dispute before a neutral panel for settlement. U.S. Benate will vote today on an amendment to delay a federally guaranteed loan to Lockheed. The vote is expected to be very close. In local news, a Texas Animal Health Commission employee said that he thinks that the Harris County vaccination program against sleeping sick- ness is almost at an end. I don't know if they're going to institute preflight quarantine on the anita-is or not.

And the Houston Astros split a twilight double header last night with the Phillies, 8 to 3 and 5 to 1. Muhammad Ali announced that - and I'11 stand - all right, Mubammad Ali announced that he will fight Jerry Quarry, Sel_tember, in the Astrodome and Ali also wants a rematch with Joe Frazier sometime in March, 1972. The Oilers have trimmed their roster to 59 players by placing two of the players, Johnny Peacock and Tom Smiley, on waivers. Four golfers were inducted into the American Golf Hall of Fame last Bight. They are Julius Boros, Cary Middlecoff, Jock Hutchinson, and the late Walter J. Travis. And we hate to tell you this, but Elizabeth Taylor is a grandmother, at age 39 when _ her 19-year-old daughter-in-law gave birth to a 6-pound_2-ounce girl yesterday.

CMP: Okay, Joe; stand by 1.
CMP: Houston, this is 15. We are ready to copy the consumables updates ...
CC: Al, stand by. We're not receiving you clearly.
CMP: Okay. We'11 stand by.
CC: Roger; it's very weak and severe noise in the background, 15. We're standing by for better COID_n.
CMP: We understand.
CC: Al, this is Houston. The noise seems to have quieted down again. Why don't we give it another try._
CC: Okay, Joe. Would you like to copy our consumables and then you can pass up S-band.

LMP: Okay, I copied all those. As far as sleep, Dave figures 8 hours in two segments; A1 was 8 hours for two; and I figure I got 9 hours in about three segments.
CC: Sounds
UNKNOWN: we copy that. like that's the most sleep you've had in several months. Out of curiosity, since we're coming up on this eye-flash experiment, I wonder if any of you has noticed any of the flashes yet?
LMP: Yes, we have noticed them both nights, Joe.
UNKNOWN: guess we'11 talk more about that a little -_ later on. I have a number of other things to rea_ up to you, in whatever order you'd like. They include a fairly extensive Flight Plan update, nothing profound but it will require some - certain amount of writing and then a few miscellaneous questions which we'd like to ask you. can
UNKNOWN: Ok - okay; I guess I start on the - these Flight Plan bit.
CC: Okay, Jim. And are you the recording secretary this morning?
CC: Okay, Jim. Before we start, did you get the radiation dosimeter readings for us?
CC: We reported them last night. Do you want them again this morning?
CC: Apparently, we'd like them again the - the - this morning on the schedule.
LMP: Okay, Joe. I have a radiation report for you.
CC: Go shead.
LMP: Okay, radiation. On Dave is 23023_ Al, 25009; and mine is 08010.
CC: We copy those, Jim_ thank you. And normally, I guess, we'd like those in the postsleep period as opposed to presleep, which is when we got them -_ yesterday. I guess it's in the checklist that way
CC: Okay, we'11 - okay, we'11 normally do it that way.
CC: Okay; fine, and I'm ready to start with the Flight Plan update. When you're set up to copy up there, I'11 start at about 54:50.
CC: Okay, let me get to 54:50.
CC: Fine, Jim. And we're coming up on an OMNI switch. When we're on the new antenna, I'11 start to read. You might want also your L_ Activation Checklist handy because we'11 be using it later on.

Before I start into it step by step, let me change just say that it's basically - the - the is basically moving some of the items around in time, changes and there's not many in procedures involved. The one main thing is we're going to ask you to go into - into the LM a little early, I guess, earlier than you had planned. And we're going to also re- quest that you give us enough - you bring enough of the telemetry on line so we look at the - can look at the LM batteries. And there's no particular reason we want to do this today. Nothing that we suspect is wrong, but rather, apparently, the sys- tems people are interested in a better granularity in data points that they're taking on these bat- teries. That's the reason for this particular addition. Other than that, I think there's no - nothing at all very - very different about this Flight Plan update, other than a few minor changes. and And I'11 go ahead start if you're ready.
LMP: Okay. I'm ready: Joe. And we understand. LM/CM
CC: Okay; 54:50, the step "If DELTA-P less than 2.7 psid, LM TUNNEL VENT valve, panel 12, vent until DELTA-P greater than 2.7 psid." LM/CM
LMP: Okay. I have "If DELTA-P, is less than 2.7 psid, LM TUNNEL VENT valve on panel 12, vent until DELTA-P greater than 2.7 psid."
CC: That's correct. Now turn one page to 55 plus 15.
LMP: Okay; I'm there.
CC: Okay. Insert "Stop PTC at roll 50 degrees. HIGH GAIN ANTENNA angles: PITCH, minus 48; YAW, plus 82."
LMP: Roger. "At 55:15, stop PTC roll 50 degrees; HIGH GAIN ANTENNA: PITCH, minus 48; YAW, plus 82."
CC: That's correct. Now, turn back several pages to 3-54_ please. And that's the "Cycle Film in Pan and Map Cameras" page - procedures page.
LMP: Okay; I have it.
CC: Okay. Down near the bottom, delete the line "SM SECTOR l, SM/AC POWER, OFF." And add in its place "MAP CAMERA on - that should read "MAP CAMERA on STANDBY/t alkb ack gray." Over.
LMP: Okay; understand. Delete "SM SECTOR l, SM/AC POWER, OFFs" and add "MAPPING CAMERA on to STANDBY/ talkb ack gray.
CC: That's correct. Now, turn back to 55 plus 50, and there's a long series of deleted activities that will follow-. These - All because we're not going -- to do a midcourse 3, as you're well aware. And I'11 call them out line by line, and they'11 carry through for - I guess about a page and a half here. At 55:00.
CC: Delete "P30 external DELTA-V" and "V49 maneuver to pad burn ATT." Turn the page. Jim, I've apparently made a mistake on that. That should have been 55:50. I think you're at the right - the right place. Con- tinuing on over to 50 - -
CC: Yes; I got it.
CC: Roger. Continuing to 56 plus 00, delete the next seven lines up to the two lines which you should leave in: :'02 FUEL CELL PURGE" and "WASTE WATER DUMP."
LMP: Okay; I have that.
CC: Okay. Continuing - continue deleting the lines below that, down to 57 plus 00.
LMP: Okay. So the only two actions we have on that page, 56 hours, is the "0o FUEL CELL PURGE" and the "WASTE WATER DUMP."
CC: That's affirm. Now, once again backing up to the time, 55 plus 50. That should read "VERB 49 maneu- ver to DM checkout attitude," and that attitude is "305, 090, 000. HIGH GAIN angle: PITCH, minus 30; YAW, 276."
LMP: Okay. "VERB 49 maneuver to DM checkout attitude" at 55:50; the attitude "305, 090, and 000; HIGH GAIN: PITCH, minus 30; and YAW, 276."
CC: Readback's correct, Jim. I'11 stand by until we get another OMNI change.
CC: 15, Houston. Our comm's quieted down again, and I'11 continue if you're ready.
LMP: Okay. I'm ready, Joe.
CC: Roger, Jim. At 56 plus 50, start "CSM Systems Checklist, IVT to DM," and this is an item that's moved up from 57:20, by the way.
LMP: Okay. At 56:50, start "CSM Checklist, IVT to I_M."
CC: That's correct, and you are to start that checklist from the beginning. And at 57 plus 00, you move the CSM PTC procedures to completion of our DM battery checkout. And I guess that's an item for Al.
LMP: Okay; understand. We'11 move all that there for the PTC until after we complete the battery checkout.
CC: That's correct, and that should come around 57 plus 50 or perhaps a little later. But, once again, not time critical. We're coming up on 57 plus 30. And, if you'11 take out your LM Activation Checklist, page l-l, please.
CC: Okay. And this is to start at 57 plus 30. Perhaps you should put a mark in your time line, but then on - on the checklist from page 1-1, delete "Comm r-_ carrier, CWG connector." Delete step 2. Delete step 5.
LMP: Okay. On 1-1, I delete "Corem carrier, CWG con- nector;'' step 2; and step 5.
CC: That's affirm. Do page 1-13. And if you'11 turn to that, do 1-13, except in step 2.
CC: In step 2, delete "VHF B TRANSMITTER, close; VHF A And RECEIVER, close; CDR AUDIO, close." add the instruction "CB 11, ECS CABIN FAN, close." under
LMP: Okay, Joe. On 1-13, step 2, to delete "VHF B TRANSMITTER, close; "VHF A RECEIVER, close; COM- MANDER AUDIO, close." And add "CB 11, ECS CABIN FAN, close."
CC: That's correct, Jim. Do page 1-14, except in step 5. Delete "VHF A TRANSMITTER, close; VHF B RECEIVER, close;" and delete step 6.
LMP: Okay. On 1-14, we'11 do all that, Under step 5, we'11 delete "VHF A TRANSMITTER, close; VHF B RE- CEIVER, close;" and want to delete step 6.
CC: Readback's correct, and add step 7. Your comm S-BAND configuration is "PM, SECONDARY, PRIMARY, OFF; PCM, OFF/RESET, OFF, and HI."
LMP: Okay. The S-BAND configuration is "PM, SECONDARY, PRIMARY, OFF; PCM, OFF/RESET, OFF, and HI."
CC: That's correct. We'11 want you to stay in the con - configuraticn for 15 minutes while we take the data. After that time, do page 1-18 and 1-19.
LMP: Understand to stay in that configuration for 15 min- utes, then do 1-18 and 1-19. Page lB3
CC: Okay, Jim. Sounding fine. Now, back into your time llne. At 57 plus 45, proceed with LM house- keeping. And we've got some words here on the housekeeping. I'11 read them to you, and I guess - Copy down whatever you think you haven't done yet.
LMP: Okay; understand. At 57:45, we're to proceed with LM housekeeping, and go ahead with the - your steps, Joe. I'11 note them down.
CC: Okay. Vacuum cabin fan filter. And as a subgroup under this, you unsnap netting around cabin fan filter.
CC: Then you vacuum the filter. But do not scrub bristles of the vacuum cleaner over the surface of filter. Then, you remove the remaining parti- cles on cabin fan filter with sticky tape, using care not to dislodge filter material.
CC: Then, you remove the particles on the inlet screen of the vacuum cleaner with sticky tape; and, finally, replace the netting.
CC: And, Jim, that's the end of that procedure. Our comm's starting to fade out on us, so we may not be able to copy you. Hopefully, you're copying us clearly still.
LMP: Yes, we are, Joe. I got that ...
CC: Okay, Jim. And Just an added note on that. As you're well aware, we're interested in cleaning up as many of those fine glass particles as we can, which is primarily the reason for - for this procedure.
UNKNOWN: Yes; we quite agree, Joe.
CC: Okay. At the time 57 plus 45, the steps "S-BAND AUX, TV to SCIENCE, PAN CAMERA POWER to on," and then in parenthesis, "for 5 minutes/OFF." and finally, "S-BAND AUX, TV to off."
LMP: Okay, Joe. At 57:45, understand you want the "S-BAND AUX, TV to SCIENCE." Then I missed the information after - after that, and then, finally, --_ the last one was "S-BAND AUX, TV to off."
CC: Okay, Jim. What we're interested in here is look- ing at the pan camera temperature. And the center step, the one you missed, reads "PAN CAMERA POWER to on for 5 minutes and then OFF."
LMP: Okay; understand. "PAN CAMERA POWER to on for 5 minutes and then to OFF."
CC: That's correct. At 57 plus 50, "CSM proceed with PTC activation."
LMP: Okay. At 57:50, "CSM proceed with PTC activation."
CC: Roger. And turning over a page to 60 hours. After the step "S-BAND AUX, TV-off," add "PAN CAMERA SELF TEST to off." And - -
LMP: Roger, Joe.
LMP: Joe, do you read me now?
CC: Okay, Jim. Reading you loud and clear.
LMP: That last information you gave me on S-BAND AUX, TV. I add %hat - I added that in at 57:45. Is that correct?
CC: Jim, no; negative. Turn over the page to 60 hours, 60 plus 00.
LMP: Okay; I have 60 hours.
LMP: Okay, Joe. I'm at 60 hours.
CC: Okay, Jim. This is a new step completely at 60 hours. We did say something at 57:45. I'11 come back to that in a minute to make sure that's straightened around. But at 60 hours, after the step in the Flight Plan, S-BAND Al/X, TV to off, add two steps. And they are "PAN CAMERA. SELF TEST to off" and ,'MAP CAMERA, ON to OFF." Over. Tape .$3/7
LMP: Okay; understand. Two steps there after "S-BAND AUX, TV-off." "PAN CAMERA, SELF TEST, off" and
CC: That sounds - that sounds good, Jim.
UNKNOWN: Let's go back to 57:45.
CC: Okay, Jim. At 57:45, the three steps you added in there should be "S-BAND AUX, TV to SCIENCE; PAN CAMERA POWER, on for 5 minutes and then off; and S-BAND AUX, TV, off."
LMP: Okay; understand that. I guess I got a little confused there, Joe, when you said turn the page, and you turned several pages to get to 60 hours.
CC: I think you caught me in that. I guess I did. Sorry.
LMP: Okay. I'm ready to go on to the next one, Joe.
CC: Okay, Jim. That completes the Flight Plan update, and you should know by now that you have to take me for what I mean, not for what I say. I do have - -
LMP: We did.
CC: Roger. I 4o have a note, which you can put down in the margin or wherever, and it involves sub- sequent P23 sightings as required.
CC: And the note is "Reduce trunnion to less than 10 degrees before zeroing optics." And then, "Always do optics calibration after optics zero in P23."
LMP: Okay, Joe. For subsequent P23 sightings, we're to reduce the trunnion to less than 10 degrees before zeroing optics, and always do the optics CAL after the optics zero in P23.
CC: That's exactly right, Jim. And that is all I have on my Flight Plan update. I guess we've got an afterthought here. I'11 get with you in a minute. _ I do have - some other questions which I'd like to ask, but let - let me give you this addition while you have the Flight Plan there on your lap. And it involves the time 56 plus 20. I'11 stand by when you' re there.
LMP: Okay. I'm at 57 - 56:20.
CC: Okay. The step is "Direct 02 open until cabin pressure equals 5.7 psia."
LMP: Okay; understand. At 56:20, "Direct 02 open until cabin pressure equals 5.7 psia."
CC: And, Jim. I'm going to wait until the comm gets a little better before I continue on here. Be a - -_ a minute or so.
CC: Apollo 15 _ Houston.
CC: Jim, we've got about three or four small questions for you. Your choice whether you'd like to talk about them now or proceed on with the light-flash experiment.
LMP: No. We're going to delay that light-flash experi- ment anyway until we get cleaned up here and have breakfast. So you can ask - ask the questions. We'11 be thinking about it while we're cleaning up.
CC: Okay. That sounds good. Our first one, we noted a very small load change on battery bus A yester- day, several minutes prior to your SP$ burn, and we're trying to - to chase down what may have caused this. We suspect that you may have - have closed two circuit breakers that should have been closed and Just are curious to know if you did close them, or if when you looked to verify them, they were already closed. And, the circuit breakers in question are the SPS PITCH 1 and YAW 1 circuit breakers that feed BAT A.
LMP: Okay. We - we closed those per checklist, Joe.
CC: Jim, I understand you closed them per the check- list. By that do you mean that you - when you looked at them, you found them open and closed them?
LMP: Okay. That's firm, Joe. They were open, and we closed them per the checklist.
CC: Okay. The guys in the back room here psyched that out pretty well, I guess. Thank you. That - I guess that was a question mostly of academic in- terest. Al, the circuit breaker in the lower equipment bay, AC 2, is still out as you're well aware, and it affects a number of EL and DSKY lights and so on, and we'11 want to talk to you later on today about this. It should be no prob- lem in any way, but we do want to talk about - discuss ramifications of the - of the various workarounds which this may involve. And, finally, we've been noting during the night some small oscillations in accumulator quantity, and we'd like for you, please, to check your SECONDARY RADIATORS. Verify that 's in BYPASS. That 's panel 377.
LMP: Okay. We're checking panel 377 now.
LMP: Okay, Joe. On that - on that valve on 377. It was in BYPASS, and Dave just cycled it to - cycled it to NORMAL and then back to BYPASS.
CC: Okay, Jim. Thank you. And that's all we have down here for the time being. I've been reading the Apollo 15 Status Report that's put out every 2 hours. What's normally several pages is just a page today. And - with very few words on it, the most prominent one being the word nominal, the meaning of which I'm going to look up as soon as I get off this shift.
LMP: Very good. --_
CC: And, Jim, unless you have any questions, why don't you proceed on with a comfortable breakfast, and we'11 be standing by for a eallout of when you're ready to continue.
CDR: Okay, Houston. We're getting ready to do the light-flash experiment, and we'd like to run the tape recorder so we can get the voice marks on it, if that won't interfere with any of your ...
CC: Okay, Dave. Stand by. I'11 inquire.
MCC: TUNNEL VENT valve.
CC: Roger. In answer to your question on the DSE, we'11 handle the DSE from down here when we start the eye-flash experiment. We do have a - a request of you before you start the experiment, though. We don't have the necessary oxygen purity in the LM yet that we think that we're going to need for the surface EVAs several days from now. And - consequently, we want you to start to vent the LM once again. We're going to drain it out and fill it with oxygen again later on today. So, if you would please, turn the TUNNEL VENT valve to the VENT position before we start the eye flash.
CDR: Okay, Joe. That's in work.
CDR: Okay, Houston. And we'11 take a couple of minutes here and run a hatch-integrity check and make sure it's all fixed up, and we'11 be with you in about 5.
CC: Roger, Dave. Sounds good.
CDR: Okay, Houston; 15. The TUNNEL VENT ... pretty good, so we can go ahead and start the experiment.
CC: Okay, Dave. We're stand by. And I could give you a few reminders on the experiment here, if you'd like them.
CC: Roger. We're just interested - in primarily a mark from each of the three of you when you notice a - a flash. And then, you might indicate who it is calling it out and then a description, as you see it: position, color, et cetera, et cetera. And - if - any - if another one of you notices one in the meantime during the description, call mark, and that one then takes precedent [sic]. Over.
CDR: Okay. That's about the way we t_lked it over, Joe. We're all set. Thank you.
CC: And, Dave, we'11 be standing by for when - -
CDR: Okay. If you'11 start the tape recorder, we'11 start.
CDR: Okay; Houston, 15. We're starting.
CC: Dave, this is Houston.
CC: Roger, Dave. And, just wanted to make sure you - understood you that we'd also prefer the mark on real time comm, as well.
CDR: Well, all right.
CC: Roger, Dave. Since I haven't heard anything, I'11 assume you haven't noticed anything yet. And I'm assuming, also, that you are wearing your eye masks.
CDR: ..., message, Joe. And the window shades are up, and the cabin is dark.
CDR: And we're concentrating pretty hard.
LMP: MARK LMP.
CC: And, Al, any sensation other than Just a flash?
CMP: Negative, Joe.
LMP: LMP MARK.
CDR: MARK CDR.
CC: Roger, Dave. And is it a - just a pinpoint, or a streak, or what?
CDR: All coming on the DSE, Joe.
CDR: We can give you that, but it might get confusing.
CDR: Houston, so far we've all seen just point sources of light, rather than streaks.
CC: Okay, Dave. And some of us are a bit - -
CMP: MARK CMP. _
CC: 15, this is Houston. If you see something signif- icantly different from the point source, we'd like a real-time voice description of it, as well as DSE recorded.
CDR: Okay, Houston. Fine. It's just that when we're trying to talk back and forth with the time delay, it's going to get confusing on the comm for us to try and record mark CDR.
CC: Understand, Dave.
LMP: MARK LMP. And this one did have a - a streak nature to it. Like it went from 8 o'clock over to - the plus-X position.
CMP: MARK cml°.
CMP: MARK CMl:'.
CC: 15, this is Houston. Are you still with us?
CDR: That's for sure. Still here. _
CC: 15, Houston. Are you still with us?
CC: Roger, Al. And we're coming up on about 10 minutes remaining.
CDR: Okay, Houston. We've got 60 minutes up here. How's your clock look?
CC: Dave. We're coming up on 60 minutes here too. And I've - I think that's certainly an adequate period. A couple of quick questions, though. Could you de- scribe for us briefly your positions in the space- craft during this time?
CDR: Okay. We've got it - several comments for you, Joe. Let us un - uncouple here, and we'11 talk to you for a while about this.
CDR: Okay. Houston, 15. I guess - we realize the in- terest behind this and the significance of the thing and - and we'11 each try and describe what we saw in the way of the flashes. And I think - because of the randomnum - randomness of the flashes, it was probably better to let us go ahead and work out the events on the DSE. And I think, also, you'11 find on the DSE, when you review the tape, that we've come up with a little scheme to give you some quantitative data, which may or not- may not be the best. And if you have any suggestions on future tests or how we can make it a little better for you, we'd be glad to hear that. As to our po- sitions in the spacecraft, we're in our launch - regular and launch positions; I'm in the left, and you still copy?
CC: Roger, Dave. Loud and clear.
CDR: Okay, I guess - as far as my impressions, I would say 90 percent of what I'd call a point source of light. And to give you perhaps an analogy, you might picture yourself sitting high in the stands of the - of the Ice Capades with the arena darkened and some single figure on the - on the ice, like Peggy Fleming, doing a nice thing. And you look across at the other side of the - the dark arena and somebody shoots a flashbulb out of their Instamatic or something, and that would be what I'd call a - a typical flash of intensity 5 on a scale i to 5, and we tried to sort these out relative to their intensities. And that - that would be my impression of 90 percent of what I saw.
CDR: Okay, let A1 give you his impressions.
CMP: Okay, Joe. I guess I didn't see the same thing that Dave did - and - talking about the intensity, I guess that's a very subjective thing. But I guess the analogy with the flashbulb ... was very good for the brighter intensities, and it seems like there was - there was one flash maybe that was of ... an intensity in the majority of the ...
CC: Hey, A1 - Stand - Al, stand by. Stand by.
CC: Al, we're starting to lose you because we're changing our OMNIs now. Could you stand by a second, and I'11 give you a call back?
CC: 15, while you're standing by waiting for the OMNI to come around where we can read you more clearly - Dave, that was a very, very nice description of the flashes. Of course, we're very pleased with the - apparently, the intensity values that you put on the - on the DSE. And I think our comm - eomm is starting to improve here, Al, so I'11 be standing by for your continued description.
CMP: Okay, Joe. I guess in addition to - to what's been said already, most of the light flashes seem to be of the order of flashcubes or maybe star- --_ bursts that you've seen in the s_mmertime. I saw very few streaks or radial paths of light. They all seem to be Just point sources of light, and - and I guess that's really about all I've got to add, Joe; I'11 - I'11 see if Jim's got something.
LMP: Joe, I just have one comment, ... that's on the tape. And that is, Just after the timing ... ended, we were taking - about to take our masks off, I had one - very brilliant streak .... - -
CC: Stand by - stand by.
LMP: - - ... at 9 o'clock - -
CC: Jim, stand by a second. Our comm's starting to - drop out 'again, and it may be a partial problem with your microphone position. Stand by just a second though, please.
CC: Okay, Jim. We have comm again. Proceed on.
LMP: Roger. I wanted to comment on one brilliant streak that I had just after the timing period had ended, and I was about - I was in the process of taking the mask off, and there was a brilliant streak, intensity 5, that went from the 9 o'clock position - through 12 o'clock - and out the $ o'clock.
CC: Roger, Jim. We copy that. And could you tell us which eye that one was in?
LMP: Well, it seemed like it went from the left eye to the right eye.
CC: Okay; very interesting. Endeavour, the principal investigators on this, Dick Benson and Larry Pinsky, have followed it closely and are quite pleased, I think, with the data you've given us, they'11 be looking at the DSE information in detail and may have a - sc_e definite procedure changes to give to you later, based on the information you've given us so far. And I guess as far as we're concerned, we have no more questions.
CDR: Okay; fine, Joe. We'11 be standing by and I - I guess another that - that you've picked up - interesting thing, is that the - the flashes are quite easily located relative to either eye or the position within either eye, which I think we found rather interesting.
CC: That's remarkable, Dave. Right; thank you.
CC: 15, when you get squared away there, we'11 be looking for - your starting to charge battery B, battery Bravo.
CDR: Roger. Understand. And I might add one more comment that - in discussing that - that last one, why, Jim didn't quite have that impression of localization within each eye, although A1 and I both do.
CC: Jim, this is Houston again. I have a small addition to your Flight Plan update which I can give you wheneyer convenient for you.
CC: Roger; whenever convenient, Jim. No hurry on it at all.
LMP: Battery charge B is in process.
LMP: Okay, Joe. I'm ready to copy these additional comments you have for the Flight Plan.
CC: Roger, Jim. The first one is at 53 hours exactly, and it's just a note for your information.
LMP: Ail right, go ahead.
CC: Roger. In the left-hand side of the Flight Plan there, the "Lift-off time (if required)." Note that it is not required in this case so we don't have to worry about that. The - second change - is possibly not a change: at 60 hours, 6 0 hours, I wanted to doublecheck your readback of the addi- tion which I gave to you earlier. And it should read, at 60 hours: "PAN CAMERA SELF TEST, off," and "MAP CAMERA ON, to OFF." Wanted to double- check that last step.
LMP: Roger. I have both of those, Joe, and they occur after the S-BAND AUX TV, OFF.
CC: Okay; thank you very much, Jim. The third change is an addition to t_e LM Activation Checklist changes which I gave you earlier.
LMP: Is it in the Activation Checklist or is it in the Flight Plan?
CC: I think you copied it in the LM Activation Check- list on pa4e 1-13.
