Okay. On panel 3: the first three steps we took care of; MODE, VOICE, to VOICE; POWER, SCE, OFF; POWER PMP to OFF; and S-BAND OMNI would go back to Bravo. Panel 225: FLIGHT BUS, MAIN B, will go open; and CB CTE, MAIN B, will go open.
-
Vance Brand (CAPCOM)
-
That's affirm. The two circuit breakers on panel 250 will go open; the two circuit breakers, panel 275, will go open. Okay, the circuit breakers on panel 250, we took care of already. Panel 3: AC INVERTER, 2, we took care of. AC INVERTER 2, AC BUS 1 should now go OFF. And the remaining two switches on panel 3 we took care of. And “Select best OMNI” remains the same. Okay. Read back.
-
Jack Swigert (CMP)
-
Okay. The two switches—two circuit breakers on panel 250 will go back to open; the two circuit breakers on panel 275 back to open; the POWER ENTRY/POSTLANDING circuit breaker, we already took care of earlier; AC INVERTER 2; we took care of earlier; AC INVERTER 2 to AC BUS 1 will go to OFF; and AC INVERTER, AC BUS 1, we took care of—No, that'll go to OFF; and UP TELEMETRY, COMMAND RESET will go OFF.
-
Vance Brand (CAPCOM)
-
That's correct, Jack. Okay, that's it. And I think we're about ready to go with this procedure whenever you are.
-
Jack Swigert (CMP)
-
Okay. First we got to go through that procedure to power the CSM from the LM, is that Charlie?
-
Vance Brand (CAPCOM)
-
No. No, this is independent of power from the LM. This is a—this is purely a CSM —
-
Vance Brand (CAPCOM)
-
This is purely a CSM powerup so we can take a look at your telemetry and see how cold the vehicle is and that sort of thing.
-
Jack Swigert (CMP)
-
Okay, now I won't—I won't have any voice with you, so—Is that right? You don't want me to get connected up—you want me to just take these readings and come back and tell you what I have, huh?
-
Vance Brand (CAPCOM)
-
I—we presume, though, that there'll be somebody in the LM that we can call if we have to get word to you.
-
Jack Swigert (CMP)
-
Oh, yes. There'll be somebody to be standing by, they'll run up into the bedroom and tell me to stop what I'm doing.
-
Jim Lovell (CDR)
-
Okay, Houston; Aquarius. Switching watches, and Jack's going up into the command module.
-
Vance Brand (CAPCOM)
-
Okay, Jim. We have four steps here to give you to request that you get back on DOWN VOICE BACKUP, if you're ready to copy?
-
Vance Brand (CAPCOM)
-
Okay. Bit rate to LO bit rate. VOICE, FUNCTION switch to DOWN VOICE BACKUP. POWER AMPs CB, open; RANGE FUNCTION switch in RANGING; that's verify.
-
Jim Lovell (CDR)
-
Okay. Bit rate, LO; VOICE FUNCTION, DOWN VOICE BACKUP; POWER AMP S-BAND, open; and RANGE FUNCTION to RANGE; and that's a verify. And I still have the BIOMED on RIGHT here, so we don't have hot mike.
-
Jim Lovell (CDR)
-
And I'm copying down the reestablishing—PTC maneuver that Charlie gave me. Step 5 was, “When rates are less than 0.05 degrees per second, ATTITUDE CONTROL YAW to PULSE.” And just how am I to get my rates down to 0.05 degrees per second. My—My rate indicator, at the best, is 0.1 of a degree.
-
Vance Brand (CAPCOM)
-
Jim, this has been tried in the simulator by Charlie and others, and what they recommend is that you null your rates on the error needles until you see no movement whatsoever, and then wait another couple of minutes, and that should do it. That's the only way we can tell. Over.
-
Vance Brand (CAPCOM)
-
Okay. And if you can't attain that, why, of course, just the best you can do. We'll have to give it a try. Maybe it won't be quite like the simulator.
-
Jack Swigert (CMP)
-
Okay, Vance. I've gone all the way through your procedure—all the way down to “Select best OMNIs,” but I'm not getting any MAIN BUS B voltage and this I don't understand.
-
Vance Brand (CAPCOM)
-
Okay. You faded out due to noise in the orientation. If you close the POWER AMP circuit breaker, we can hear you better. Over.
-
Vance Brand (CAPCOM)
-
Okay. You faded out at the very beginning, so please go through that again. We understand you don't get anything on MAIN B.
-
Vance Brand (CAPCOM)
-
Okay, Jack. Please, repeat back now your conversation. You were cut out for—a while ago.
-
Jack Swigert (CMP)
-
I don't have any idea where we cut out, Vance. I just said that we performed the procedure exactly as you say. We're down into the SEP critical portion to where I said, “select best OMNI.” However, we're not getting any MAIN BUS B voltage reading. I can read BAT BUS B, Baker, at 36.5; BAT Charlie at 37.0, but I have negative MAIN BUS B readings.
-
Vance Brand (CAPCOM)
-
Okay, Jack. There are two—There's a switch and a circuit breaker that were positioned this morning that we'd like to have you check—Correction, just the switch. Panel 5, check your bus tie. MAIN BUS TIE BAT B/C on.
-
Vance Brand (CAPCOM)
-
Okay. We're getting data from you, Jack, so that much looks good. On panel 5, request verification that EPS SENSOR SIGNAL circuit breaker is MAIN B. Over.
-
Jack Swigert (CMP)
-
Well, Vance, if you're getting data from them, let me go back up there and finish the …
-
Jack Swigert (CMP)
-
Okay, Vance. Okay. We just changed OMNIs here. I say, if you're getting data from us, that's the important thing. Let me go back up into the bedroom there and get the readings you wanted, so we can get this stuff powered down. Is that okay?
-
Jack Swigert (CMP)
-
Okay, Vance. We'll go back up—We've got voltage now, and we'll go back up and take the readings that you want.
-
Jack Swigert (CMP)
-
Okay. I'm going back up to the bedroom. We'll select best OMNI and continue on with the procedure.
-
Jim Lovell (CDR)
-
And, Houston, I noticed through the AOT and through the overhead docking window that we are venting again.
-
Vance Brand (CAPCOM)
-
Jim, would you holler into the bedroom and tell Jack that when he has his onboard readouts that we wish he'd back—use the backout procedure and shut down again—per the procedure we gave him.
-
Jim Lovell (CDR)
-
Roger. As soon as he—As soon as he gets his onboard readouts to use the powerdown procedure and shut down. Is that right?
-
Jim Lovell (CDR)
-
Okay. Jack just—Jack just told me that he's through, and he's going to go through the backout procedures again, the first one he's got is the shutdown.
-
Jack Swigert (CMP)
-
BAT Charlie, 37.0; pyro A, 37.0; pyro B, 37.0; SPS helium pressure, 3450; and just for kicks, nitrogen A, 2300; nitrogen B, 2400; CM RCS injector temperatures: 5 Charlie, 4.5; 5 Dog, 3.5; 6 Alfa, 4.0; 6 Baker, 4.6; 6 Charlie, 4.0; 6 Dog, 3.8; battery manifold pressure, 4 Alfa, 1.4.
-
Jack Swigert (CMP)
-
I'll tell you, Deke, it's cold up in there. I don't know whether we'll be able to sleep up there tonight; it must be about 35 or 40 degrees.
-
Vance Brand (CAPCOM)
-
Jim, two items: in the command module, we wish to verify that the PYRO BATTERY selector was left in the main position. And we're ready to have the POWER AMP circuit breaker on panel 16 pulled, whenever you are ready.
-
Jim Lovell (CDR)
-
Okay, Vance. Fred just tells me that he put it there, and we're checking that again about the PYRO BATTERY selector in the main position.
-
Jim Lovell (CDR)
-
Houston, Aquarius.
Expand selection down Contract selection up -
Vance Brand (CAPCOM)
-
Jim, it looks like it was probably a sensor problem; the battery number 2 is load-sharing well. And we see no indications of higher temperatures in the glycol loop or anything that would make us think that it is heating up.
-
Jim Lovell (CDR)
-
I just want to talk over a little philosophy here. Fred told me that at one time you came up and told him that we were a little steep on the entry angle, and now our burn is going to make us—give us a steeper angle. I just want to make sure that we're all talking about the same thing, that, in essence, at this particular situation, we're shallow, are not steep, and we are going to increase the angle.
-
Vance Brand (CAPCOM)
-
Jim, the situation is that, at the moment, we're a little bit shallow, and retrograde midcourse is going to put us more in the center of the corridor. Over.
-
Jim Lovell (CDR)
-
Okay; fine. I just wanted to make sure. Fred had written down some time ago, that—that our angle now was about 71 and we were going to do a midcourse of 7 feet per second because its appears that we're going to shallow it out. I think we're all talking the same language now.
-
Vance Brand (CAPCOM)
-
Roger. And, I guess it follows, but your perigee is a little bit high right now, too; so that will be bringing it back—back down, that is.
-
Vance Brand (CAPCOM)
-
One other question, Jim. Our readings down here say your LM cabin's about as cold as the command module cabin. Is that right?
-
Jim Lovell (CDR)
-
Well, we really don't know. There's usually two people in the LM cabin, and it's a lot—It seems to be a lot more compact, and so we don't notice the coldness down here as we do in the command module.
-
Jim Lovell (CDR)
-
Some time ago, I copied down a long COMM midcourse-7 corridor control burn at a GET of 134:59:42.98. Is that burn pad still valid?
