Spacelog Apollo 13

Yes, sir. Loud and clear.

Okay. It's perform CM—CSM RCS preheat, and could you say again all after?

Okay. I'm referring to the entry checklist, page E/1-5, steps 35 and 37.

Okay. Perform CSM RCS preheat per entry checklist, page 1-5, steps 35 and 37.

That's affirmative. Now back to panel 5: circuit breaker CAUTION AND WARNING, MAIN B, closed.

CB CAUTION AND WARNING, MAIN B, closed.

That's affirm. On panel 2: CAUTION AND WARNING POWER to 1.

Panel 2: CAUTION AND WARNING POWER to 1.

That was POWER to number 1, Jack.

CAUTION AND WARNING POWER to 1.

Okay. On panel 5: circuit breaker EPS SENSOR UNIT, DC BUS A and B, closed.

Okay, Ken. The COMM from you is awful weak—awful weak, I—I can't—it's CB EPS SENSOR UNIT. Say again, after that.

All right, Jack. That's CB EPS SENSOR UNIT, DC, that's Delta Charlie, BUS A and B, closed.

Okay. CB EPS SENSOR UNIT, DC BUS A and B, close. And I'll give you the volts and amps.

Okay, that's correct. Go ahead.

Okay. Volts are 39.1; amps, 1.5.

Okay. On panel 3: MAIN BUS A and B, go to RESET and leave it in the center.

Okay, panel 3—Stand by; got to change OMNI's.

Okay. MAIN BUS A and B, RESET, then center.

That's affirmative. Okay, now we're at EI minus 5 plus 05. And, as far as you're concerned, Jack, the command module is using this for information only. This will be the LM doing an Earth-terminator AGS alinement; and at the time of 5 plus 05 is the time they'll be going ahead and releasing their ball. And this will be covered in the LM checklist; it'll be uplinked after this one. At EI minus 5, we perform midcourse number 7. Over.

That's correct. At the completion of midcourse 7, the LM will maneuver to a separation attitude. And this attitude will be sent up on one of the pads that you're going to get before all the sequence starts. And it'll be flown to the LM ball angles on that pad.

Okay. Understand.

All right. At EI minus 4 plus 40, we want to perform page 1-6, step 39 of the entry checklist.

Ken, I—I didn't get it. We had to change OMNI's again. Could you say it—the EI minus 4 dash—or 04:40, we do something.

Okay. And at that time, you'll want to perform step 39 of page E/1-6. Over.

Okay. Perform step 39 of entry checklist page E/1-6.

That's correct. Okay. The next is the command module RCS activation, and that's step 4-1 of page E/1-6.

Okay. The next is perform CSM—or CM RCS activation for step 4-1 of page E—E/1-6.

That's correct.

All right, Jack. The next is at EI minus 4 plus 30. We want to verify that the LM is configured for command module RCS hotfire.

Okay. Verify LM configure for RCS hotfire at EI minus 04:30.

That's correct. Now to panel 5: circuit breaker G&N IMU HEATER, MAIN B, closed.

Okay. Panel 5: CB G&N IMU HEATER, MAIN A and MAIN B, closed.

That's negative, Jack. That's MAIN B only.

Okay. MAIN B only.

I'm sorry; I lost you that time. Say it again.

Okay. Let's repeat it. Stand by. Cut out. We've really got a strange attitude, so this is why we are having the COMM problem. Panel 5: CB G&N IMU HEATER, MAIN B, closed.

That's affirmative. On panel 1: ROTATION CONTROL POWER, NORMAL. That's two of them, to AC/DC.

Okay, panel 1: RHC, NORMAL, two to AC/DC, two controllers.

That's correct. On panel 7: SCS, LOGIC POWER 2/3, ON.

SCS, LOGIC POWER 2/3, ON, panel 7.

That's affirm. Back to panel 2: RCS COMMAND, ON.

Panel 2: RCS COMMAND, ON.

That's correct. Now the command module RCS check per step 4 of page E/2-1.

Okay. Perform the command module RCS check per step 4, page 2-1.

That's correct. Okay, at this point, we want to lock the rotation hand controllers.

Okay. After that, lock both rotation hand controllers.

That's affirm. On panel 8: SEQUENTIAL, PYRO ARM, two to ARM.

Okay. Panel 8: set PYRO ARM, two, to ARM. Do I get a MSFN GO for that?
