Jim Lovell (CDR)

Okay. Understand; and do you want some sort of a PTC mode, Jack?

Jack Lousma (CAPCOM)

Affirmative. We'll take whatever PTC mode you can set up, Jim.

Jim Lovell (CDR)

Okay. And since you know our approximate attitude, how about just getting me something to find you on the DSKY for a southerly plus X-direction.

Jim Lovell (CDR)

And one other question, Houston. When you say power down the DSKY or the LGC, do you mean going into 06 or multiple circuit breaker?

Jack Lousma (CAPCOM)

Stand by on powering down the DSKY, Jim. We'll give you the procedure for that. The procedure that we —

Jack Lousma (CAPCOM)

— the procedure that we have is listed in several places. It's in the Contingency checklist under “Power down” on page 1, second paragraph.

Jack Lousma (CAPCOM)

And we'll give you that word when we want you to do that. That's LGC only, not to power down the IMU. But we'd like to have you hold off on that until we send you the word. Over.

Jack Lousma (CAPCOM)

And, Aquarius, while we're working on this, we have a proposed flight plan update for your working and resting cycles. And—You ready to copy?

Fred Haise (LMP)

Okay. Do you want me to write this in the flight plan, per se, Jack?

Jack Lousma (CAPCOM)

You can probably write it on a piece of scratch paper. This is pretty easy.

Fred Haise (LMP)

Okay. Go ahead. We got a lot of scratch paper.

Jack Lousma (CAPCOM)

Okay. We're suggesting that the LMP rest while the CMP and CDR are awake. LMP ought to hit the sack at about 63 hours, coming up in 25 minutes. And you get to rest for 6 hours. You get up at 69 hours. At 70 hours, the commander and the command module pilot sleep for 6 hours until 76 hours. Around 70—76-1/2 to 77 hours, we'll do a P51 and a 52. At 78:30, we'll load P30 and aline AGS to PGNS. Our ignition time for a second burn will be, presently, 79:25:26.5, and we'll have a pad for you shortly. We suggest that all of you eat after the burn. That'll be 81 to 82 hours. Let the CMP and CDR eat while you are sleeping. And that you grab a bite as soon as you can. Over.

Fred Haise (LMP)

Okay, Jack. As I read that, the LMP is to go to sleep at 63:00 for about 6 hours. During that period, the CDR and CMP should try to get a bite to eat. I'm to awake at 69 hours. CDR and CMP sleep at 70 hours, and they are to awake at 76 hours. And we should plan on doing our P51, P52 at 76 hours or 76:30. At 78:30, we're going to load a P30 and aline AGS to PGNS. Second maneuver is to take place at 79:25:26.5 for ignition time. Then we're all to eat at 81 to 82 hours.

Jack Lousma (CAPCOM)

Okay. With a minor modification, your P51, P52 will be about 77 hours, and that's the period of darkness. And the commander and the CMP ought to eat around 68 to 69 hours, and you should eat between 69 to 70 hours just after you get up. We have left an hour in there where everybody is awake together to talk things over. Go ahead.

Fred Haise (LMP)

Okay. I'll eat after I wake up between 69 and 70.

Jack Lousma (CAPCOM)

All right we have additional —

Fred Haise (LMP)

— and I've got the correction to P —

Fred Haise (LMP)

Yes. We got the word the P51, P52 is going to be done around 77 hours, while we're in darkness.

Jack Lousma (CAPCOM)

That's affirmative. And we have a work-rest cycle laid out for further on, which we can relay to you later.

Jim Lovell (CDR)

Okay. And, Houston, you have advice on what attitude you want me to go to.

Jack Lousma (CAPCOM)

Okay. That'll be the next bit of information. I'll get that for you, Jim.

Jack Lousma (CAPCOM)

And, Aquarius, just to get you thinking in that direction, we've run a fairly thorough analysis, and we've found out that it's going to be cheaper to keep the LGC and the DSKY up and turn the inverter and the ball off. It's going to save us 1 amp and also some water, so it looks like what we're going to do. And we'll have to monitor the middle gimbal angle. And we'll get the procedure on that, and it'll also be an easier control mode where we'll be able to use the TTCA through the—through the DAP.

Jim Lovell (CDR)

That sounds great, Jack.

Jack Lousma (CAPCOM)

Aquarius, Houston. We've got a procedure for you. Ready to copy?

Expand selection up Contract selection down Close
Jack Lousma (CAPCOM)

Okay. It's pretty easy. We see you've already got VERB 16 NOUN 20 called up there and so we want you to, in maneuver and PGNS ATTITUDE HOLD, use the TTCA. We want you to, on the commander's ball, pitch to 267.5 and yaw to minus 4.5. And when you do this in VERB 16 NOUN 20, on the DSKY, you ought to read plus 00120, plus 26750, and plus 00450. Go ahead.

Fred Haise (LMP)

Okay. We're to drive the commander's ball to a pitch of 267.5, yaw minus 4.5. And we should have in 16 20 at that time, plus 00120, plus 26750, plus 00450.

Jack Lousma (CAPCOM)

That's a good readback. We'll watch the maneuver.

Jim Lovell (CDR)

Roger. You didn't mention roll on the ball. Do you want roll zero?

Jack Lousma (CAPCOM)

The roll ought to be plus 1.2, Jim.

Jim Lovell (CDR)

Okay. We're just about there in pitch and in … middle gimbal angle, but that other gimbal angle didn't look like it pulled the right way. I tried both methods.

Jack Lousma (CAPCOM)

Yes. I been looking at that, too, and we're asking why, and we'll get an answer for you.

Fred Haise (LMP)

Yes. Houston, I wonder if you're accounting for being a bit off the bellyband here, and I've gone through GASTA.

Jack Lousma (CAPCOM)

And, Fred-o, I know you're supposed to start sleeping here pretty soon, but we got a new PC plus 2 pad, P30 maneuver pad for you.

Fred Haise (LMP)

Okay. Go ahead, Jack.

Jack Lousma (CAPCOM)

Okay, Fred. P30 maneuver purpose is PC plus 2, DPS to this time, we're going to the MPL. And NOUN 33, 079, 27, 4013, plus 08144, minus 00443, minus 02226, apogee is N/A, perigee is plus 00205, 08455, 420, 268, 261, plus 08155, minus 00443, minus 02187, COAS is N/A. Your GDA ought to be okay as it is from the last burn, but pitch ought to be at 5.85; in roll, it's 6.74. Your ullage will be two jets for 10 seconds. Your DPS throttle will be 10 percent for 5 seconds, 40 percent for 21 seconds, and the remainder at full throttle. And for your information, this will put you in the water at 142 plus 47. Over.

Fred Haise (LMP)

Okay. DPS, pericynthion plus 2 into the MPL, 079, 27, 4013, plus 08144, minus 00443, minus 00226, N/A, plus 00205, 08455, 4 plus 20, 268, 261, plus 08155, minus 00443, minus 021, 2187, N/A. GDA should be okay as is, which hopefully is pitch 5.85, yaw 6.74. Two-jet ullage for 10 seconds, the DPS throttle 10 percent for 5 seconds, 40 percent for 21 seconds, 100 percent for the rest of the burn. And this should put us into the water at 142 plus 47.

Jack Lousma (CAPCOM)

Okay, Fred. I have a correction in NOUN 81. DELTA-VZ is minus 02226. Read back.

Fred Haise (LMP)

Okay. DELTA-VZ in NOUN 81 is minus 02226.

Fred Haise (LMP)

Somehow that didn't add up with the DELTA-VX to give a DELTA-VR of that magnitude. It seems like it'd been bigger.

Jack Lousma (CAPCOM)

Okay. We'll take another look at it, Fred.

Jim Lovell (CDR)

Okay, Houston. I'm not having too much luck holding this particular attitude.

Jack Lousma (CAPCOM)

Okay, Aquarius. When you get her pretty much in attitude there, and it looks like you're as close as we need to be, we'd like to try a control mode and see if it will work; sort of a semi-PTC. We'll leave the ball powered up for this, and if this doesn't work, why, we'll have to revert to ATTITUDE HOLD mode. But—Stand by 1, please.

Jack Lousma (CAPCOM)

We'd like you to think about this control mode, Jim, and see if you think it might work from what you know right now. We're a little skeptical, but we'd like to put it to you. So, once you get in a pretty good attitude, monitor in VERB 16 NOUN 20, go to PGNS MINIMUM IMPULSE, VERB 76, as we have, and set up a yaw rate—yaw rate to the right. Monitor the middle gimbal on R3 on the DSKY and see if she'll kind of stabilize out. If not, the only other suggestion we've got is to go to PGNS ATTITUDE HOLD. We'll keep the ball up until you make this evaluation.

Jim Lovell (CDR)

Okay, Houston. You cut out, say again.

Jack Lousma (CAPCOM)

Okay. Where'd you lose me, Jim?

Jim Lovell (CDR)

I lost you when you said try the control mode; you're a little skeptical.

Jack Lousma (CAPCOM)

Okay. From what you say, we have to be a little skeptical of this procedure, but we'd like to have you try it and have you evaluate it. You can monitor the middle gimbal on R3. Before we power down the ball, we want your evaluation. The next best choice is PGNS ATTITUDE HOLD. Over.

Jim Lovell (CDR)

Okay. Go ahead with the control mode procedure.

Jim Lovell (CDR)

Hello, Houston; Aquarius.

Jim Lovell (CDR)

Okay. I'm not … you. I can monitor register 3. I can probably keep it out of …—going into gimbal lock.

Jack Lousma (CAPCOM)

Roger. How are pitch and roll?

Jim Lovell (CDR)

Okay. I think I can control the gimbal angles in 16 20 with the compressors the way they are, but I'll have to try MINIMUM IMPULSE—just a minute.

Jack Swigert (CMP)

Okay, Jack. I've a question—one more question about Odyssey.

Jack Swigert (CMP)

Okay, I still have the PYRO A sequence A and PYRO B sequence B circuit breakers in. Do you want those out?

Jack Lousma (CAPCOM)

Odyssey, Houston. The two circuit breakers you referred to, leave them in.

Jack Swigert (CMP)

Okay. Copy. Leave them in.

Jim Lovell (CDR)

Okay, Houston. I can control yaw in minimum impulse, but stand by on pitch.

Jack Lousma (CAPCOM)

And, Fred-o, the DELTA-VR resultant computes with the components.

Jim Lovell (CDR)

Fred's off the COMM now, Jack.

Jack Lousma (CAPCOM)

Roger. Your PAD is good.

Fred Haise (LMP)

And, Jack, we didn't get that whole sentence there.

Jack Lousma (CAPCOM)

Okay. I said that the DELTA-VR that Fred questioned computes well with the component—its rms.

Jim Lovell (CDR)

Okay, now. Jack, let's go over this once more. You wanted me to try out control of the spacecraft in the PULSE mode. Is that correct?

Jack Lousma (CAPCOM)

That's affirmative. Set up a yaw rate and monitor the middle gimbal angle.

Jim Lovell (CDR)

Okay. I can do that. I'm not too sure whether I can control roll or pitch in pulse, but I can control yaw in pulse—yaw in pulse on the ball.

Jack Lousma (CAPCOM)

Roger. And remember we're not going to have a ball there, so that we're going to be monitoring CDUs on the DSKY, and if we get it off, it will be pretty hard to figure out where to fly back to; and, well, in addition, have to control the OMNIs while we're doing this.

Jim Lovell (CDR)

Without the ball, I still have use of the TTCA for control of the—angles.

Jack Lousma (CAPCOM)

Affirmative. You'll have the TTCA for pitch and roll.

Jim Lovell (CDR)

Okay. I think I can do that without the ball, and if you just give me the TTCAs I think I can control the spacecraft using 16 20.

Jim Lovell (CDR)

I'm going to yaw right.

Jim Lovell (CDR)

Okay, Jack. I am now—The REGISTER 1 is in the DECREASE mode.

Jim Lovell (CDR)

And, Houston, do you see anything wrong with this spacecraft motion?

Jack Lousma (CAPCOM)

We have a data drop on right now, Jim; we'll look at it as soon as it comes up.

Jack Lousma (CAPCOM)

Okay, Aquarius. We're going to dispense with this control mode. We'd like you to fly the machine back to the original attitude that you had, and we'll go PGNS ATTITUDE HOLD, and then we've got to get that ball off the line to save some power. And then, in order to keep even heating, every 15 or 30 minutes, we'll give you a call to give us 90 or 180 degrees of roll—of yaw.

Jim Lovell (CDR)

Okay. You want me to go back to original attitude. I'll be going back to it now.

Jim Lovell (CDR)

Okay, Houston; Aquarius. I'm flying it back over towards the initial angles you gave me of a pitch of 257. I'll get near the bellyband in roll and yaw; then I'll go to PGNS ATT HOLD.

Jack Lousma (CAPCOM)

That's affirmative, Jim. And then we're going to have you go through a powerdown procedure.

Jack Lousma (CAPCOM)

And you'll need VERB 77 with ATT HOLD when you get there.

Jim Lovell (CDR)

Okay, Jack. Have I gotten your 360 on yaw and roll? I'm going to go to ATT HOLD.

Jack Lousma (CAPCOM)

Roger. And then we want to get the ball part down.

Jim Lovell (CDR)

Okay. I'm now in PGNS ATT HOLD. And are you reading my DSKY angles?

Jim Lovell (CDR)

Now, you want me to power down the ball, and if you'll give me the procedure for that, I'll do it right away.

Jack Lousma (CAPCOM)

Okay. We'll buy what you've got on the DSKY there, and we'd just like to go through an overall powerdown procedure, and in so doing we'll catch the ball and inverter and it will only take a few minutes. So are you ready to start on panel 11?

Jim Lovell (CDR)

Roger. Jack will copy, and I'll do the work.

Jack Lousma (CAPCOM)

Okay. Panel 11, top row, open all the circuit breakers.

Jim Lovell (CDR)

All circuit breakers on top row coming open.

Jim Lovell (CDR)

They're all open, top row.

Jack Lousma (CAPCOM)

Okay. Second row, close the first six on the left through the ISOL VALVE and open all to the right of that.

Jim Lovell (CDR)

Okay. First six on the left are closed—That's through the ISOL VALVE, but I opened up every one from there on.

Jack Lousma (CAPCOM)

Okay. Third row, open up the next five—correction—Open up the first five on the left, close AOT HEATER, close SIG CONDITIONER 1. Close ATTITUDE DIRECT, and open the rest on row three.

Jim Lovell (CDR)

Do you want ATCA (PGNS) open?

Jack Lousma (CAPCOM)

Leave ATCA (PGNS) closed; four breakers on the third row must be closed. AOT HEATER, SIG CONDITIONER 1, and ATCA (PGNS), ATTITUDE DIRECT CONTROL. Our mistake, good going.

Jim Lovell (CDR)

Okay. I'm opening up ENGINE START OVERRIDE right now. And that row's taken care of.

Jack Lousma (CAPCOM)

Okay. On the fourth row. Open—From the left, open the first five—correction—Close the first five, and open CABIN FAN 1. Close the three GLYCOL PUMP circuit breakers; open all the COMM breakers, except for COMMANDER'S AUDIO; close it. All the PGNS breakers, open—correction—Open the first three PGNS breakers, close LGC/DSKY, IMU STANDBY, IMU OPERATE.

Jim Lovell (CDR)

That's complete, Jack.

Jack Lousma (CAPCOM)

Okay. And EPS, close BAT FEED TIES, CROSSTIE BAL LOAD, and open the CROSS TIE BUS. Close the next three; open ASCENT ECA CONTROL, ASCENT ECA, and INVERTER 1. Close DC BUS VOLT. Go ahead.

Jim Lovell (CDR)

That's complete, Jack. Panel 11 is configured.

Jack Lousma (CAPCOM)

Okay. Let's go over to panel 16, top row, and starting from the left—Open the first four.

Jim Lovell (CDR)

Okay. Starting from the left, open the first four.

Jack Lousma (CAPCOM)

Okay. And close the ISOL VALVE, keep your TCA breakers closed, close the CROSSFEED, open the next two displays. Close the MAIN SOV and the PROPULSION breakers should all three be open.

Jim Lovell (CDR)

Roger. The main valves are closed, and the DISPLAY ENGINE OVERRIDE LOGIC's coming open, and the PQGS and ASC He REG are open.

Jack Lousma (CAPCOM)

That's affirmative. The second row: they should all be open except for three breakers under instrumentation. Close SIG SENSOR, PCM/TE, and SIG CONDITIONER 2. Over.

Jim Lovell (CDR)

Roger. Do you want SUIT FLOW CONTROL open?

Jim Lovell (CDR)

ENGINE ARM coming open and ASA I guess will be open. Is that correct?

Jack Lousma (CAPCOM)

We just got a change on that. Let's keep the ASA closed.

Jim Lovell (CDR)

How about SUIT FLOW CONTROL and ENGINE ARM?

Jack Lousma (CAPCOM)

Okay, Jim. SUIT FLOW CONTROL can be open, and ENGINE ARM—ENGINE ARM open.

Jim Lovell (CDR)

Okay. Let's go to row 3.

Jack Lousma (CAPCOM)

Okay. Row 3 under COMM. Open DISPLAYS, close SE AUDIO, open VHF A TRANSMITTER and B RECEIVER, close the PRIMARY S-BAND circuit breakers, both of them. Open the S-BAND ANTENNA, PMP closed, TV open, and all the rest of them open under ECS, except CO2 SENSOR, closed.

Jack Lousma (CAPCOM)

Okay. Under row 4: under HEATERS, your RCS QUAD heaters should—four of them—be closed, open DISPLAYS, open S-BAND ANTENNA, open SEQUENCE CAMERA. Under EPS, open DISPLAYS, close DC BUS VOLT, open INVERTER 2, open ASCENT ECA CONTROL and ASCENT ECA, close DESCENT ECA, DESCENT ECA CONTROL, TRANSLUNAR BUS TIE, close CROSS TIE BAL LOADS, open CROSS TIE BUS, close BAT FEED TIES. Over.

Jim Lovell (CDR)

That's been completed, Jack.

Jack Lousma (CAPCOM)

Okay, Jim. And we've already got a change to what we just told you. Under ECS, close the CABIN REPRESS, and insure that the ASA BREAKER is closed under S and C.

Jim Lovell (CDR)

The ASA BREAKER is closed, but I closed the CABIN REPRESS.

Jack Lousma (CAPCOM)

Okay, Jim. Looks like what we have to do is—In order to maintain even heating, we just have to yaw the whole machine about 90 degrees per hour in increments. So we'll give you a call when it's time to yaw 90 degrees.

Jim Lovell (CDR)

Okay. We have to YAW the machine as I understand it, Houston, and you'll give it to me in increments of 90 degrees.

Jack Lousma (CAPCOM)

Okay, Jim. Your present configuration has the following features. We got the electrical BUSES cross tied through the BAL LOAD circuit breakers, and we have AUTO CABIN REPRESS. One thing we'd like to do right now is to give you an uplink, so immediately we have to, on panel 11, close the UPDATA LINK circuit breaker. Go to P00 and DATA. Over.

Jim Lovell (CDR)

Okay. We're going to P00 and DATA. The circuit breaker is closed.

Jim Lovell (CDR)

Houston, Aquarius. Did you say that you had a new pad for us to copy?

Jack Lousma (CAPCOM)

Jim, I passed that newest pad that we have to Fred about 30 minutes ago. That's our latest. It's PC plus 2, and it begins with NOUN 33 of 79 hours 27 minutes and 40.13 seconds. You got that one?

Jim Lovell (CDR)

Okay. We've got that one. What kind of a ATT HOLD MODE do you want us to do? Do you want us to do WIDE DEADBAND? I didn't … on the DAP.

Jack Lousma (CAPCOM)

Jim, the deadband is good the way it is. It's 5 degrees, if you want to stay in it. And stay in the PGNS ATT HOLD mode.
