Spacelog Apollo 13

Okay. It says maneuver in ATT HOLD for Moon view attitude until CM platform release.

That's affirm. Better worded, it would have been maneuver and hold in attitude for Moon view, et cetera.

Okay. That's mainly for Jack to be able to get it in the optics, you mean.

Yes, that's correct. Okay, Fred —

Okay.

Could you give us a readback on everything up to this point?

Okay. I'll go back to NORMAL VOICE. It might—Or is this pretty clear?

It's clear.

Okay. The master title, “Entry, LM PREP, EI minus 6 hours.” First, BAT 5 NORMAL FEED, ON; second, use modified LM DPS/RCS, 30-minute activation checklist. Next, is at TEI minus 5 hours, MCC-7, if required. Now, we have a LM preentry procedure. First, we maneuver to service module SEP attitude. Second, configure for CSM hotfire. Under that, DEADBAND MAX, and ATTITUDE CONTROL, three, to PULSE. Thirdly, perform CSM hotfire. Fourth, we—The LM maneuvers back to SM SEP attitude, with ATTITUDE CONTROLs, PITCH and ROLL to PULSE, ATTITUDE CONTROL, YAW, to MODE CONTROL. Now, you got that so far, Vance?

That's correct so far, Fred-o.

Okay. At EI minus 4-1/2 hours, configure for SM SEP. First, BALANCE COUPLE, ON. Secondly, zero the counters in AGS; 404, 405, 406, plus 0; read out 470. Thirdly, translate plus-X to 0.5 foot per second. Fourth, CM/SM SEP. Fifth, after SEP, null 470 to 0. Sixth, ATTITUDE CONTROL, three, to PULSE. Seventh, pitch to acquire service module for photos. And a note, use the ACA for control. Last, we had—you gave me was TEI minus 3 hours. Maneuver in ATT HOLD for Moon view until the CM platform release.

Okay, Fred. Only—Only a minor point that we just picked up. At the very top, EI minus 6 hours, the title is “power up,” above BAT 5 NORMAL FEED, ON.

Okay. The title above BAT 5 NORMAL FEED, ON, is “power up.”

Okay. And on the last, it was maneuver and ATT HOLD for Moon view attitude until CM platform release. I think that's what you read. Okay. Ready to go on? EI minus—Are you there?

Okay. Next is—Okay. Next is TEI minus what, Vance?

It's—It's EI minus 2-1/2 hours, Fred.

Okay. EI minus 2-1/2.

Okay. The title, “Power removal from CM LM umbilical.”

Okay. “Power removal from CM LM umbilical.”

That's correct. Next, assumes—This assumes all descent batteries on line.

Okay. I'll put that as a note.

And ASCENT BATTERIES 5 and 6 on NORMAL FEED.

Okay. This assumes all descent BATs on line, and ASCENT BATs 5 and 6 on NORMAL FEED. Go ahead.

Roger. Next, CSM CB LM POWER 1, MAIN B to open.

Okay. CSM, CB LM POWER 1, MAIN B, open.

Next. CB, LM POWER 2, MAIN B, open.

Okay. CSM, CB LM POWER 2, MAIN B, open.

CB EPS SENSOR SIGNAL, MAIN B to open.

Okay. CB EPS SENSOR SIGNAL, MAIN B, open.

Okay. Next, the LM. CB, EPS panels 11 and 16, CROSS TIE BALANCE LOADS to close.

Okay. On the LM side now. CB EPS 11, panels 11 and 16, CROSS TIE BAL LOADS, close.

That's correct. Next, CB EPS panel 16, BAT FEED TIE, two of them, open.

Okay. LM, CB EPS, panel 16, BAT FEED TIE, two, open.

Okay. CB EPS 16, ASCENT ECA CONTROL to close.

Okay. CB EPS panel 16, ASCENT ECA CONTROL, close.

Correct. BATTERY 1, HI VOLT—HIGH VOLTAGE to OFF/RESET.

Okay. BATTERY 1, HI VOLT, OFF/RESET.

BATTERY 5, OFF/RESET.

Okay. BATTERY 5, HI VOLT—or, it should be BATTERY 5 NORMAL FEED to OFF/RESET.

Roger. And—Stand by.

Or did you mean battery 2?

Yes. I think that's what he meant.

Okay. We mean BATTERY 5 to OFF/RESET.

Okay.

That's a NORMAL FEED.

BATTERY 5, NORMAL FEED—NORMAL FEED, OFF/RESET. Got you.

Okay. BAT 2, LOW VOLTAGE, OFF/RESET then ON.

Okay. BATTERY 2, LOW VOLT, OFF/RESET, then ON.

Next. BAT 2, HI VOLT, OFF/RESET, then ON.

Verify CM free.

Okay. Next, the COMM configuration. S-BAND, PM, PRIM.

Hold on. Say again now.

Okay. Next, COMM configuration.

This is for the command module?

Negative. The step above for CM free was command module, but the COMM is for LM again.

Okay. Go ahead.

Okay. S-BAND, PM, PRIMARY, PRIMARY again, OFF, PCM, RANGE, OFF, and HI.

Okay. Our S-BAND CONFIG is: PM, PRIM, PRIM, OFF, PCM, RANGE, OFF, HI.

That's correct. Stand by 1.

Do you have any druthers about which OMNI?

Yes. Select best OMNI.

Select—Did you say AFT, or best?

Best. Best in the west.

Okay. I was wondering if that's still going to be best after it leaves—But, okay. Select best OMNI at the time.

That's affirm. Okay. We've covered COMM, Fred. Next, ECS.

Okay. Go ahead.

Okay. Under ECS, FORWARD DUMP valve, close.

Okay. FORWARD DUMP valve, close.
