Spacelog Apollo 13

Roger.

13, Houston. Level sense arm time 8 plus 38 nominal; S-II cut-off time 9 plus 48. Over.

Roger. Nominal on the level sense arm, 9:48 on the S-II cut-off.

That's affirmative, and stand by for S-IVB to orbit.

MARK.

You have S-IVB to orbit, Jim.

Roger. We have S-IVB to orbit.

13, Houston. Looking good at 8 minutes.

13; Roger.

Apollo 13, Houston. Mark level sense arm.

Mark level sense arm. Roger.

Apollo 13, Houston. At 9 minutes, you are GO; the CMC is GO.

Okay, Joe.

13; Roger.

13, Houston. You are GO for staging.

13; Roger. GO for staging.

Apollo 13, Houston. Stand by for mode IV capability.

MARK.

You have mode IV, Jim.

Mode IV. Roger. Staging.

Roger. Staging.

And S-IVB ignition, Houston.

Roger that, Jim. Thrust looks good.

Roger.

13, Houston. You're looking good. Trajectory, guidance, CMC are all GO.

Thank you, Joe.

13, Houston. At 11 minutes, you're GO. Predicted cut-off on the S-IVB is 12 plus 34. Over.

Apollo 13, Houston. You're GO at 11-1/2, and predicted cut-off time is 12 plus 34. Over.

Understand; 12 plus 34 predicted cut-off time.

That's affirm.

SECO.

Copy SECO, Jim. We're looking at the DSKY.

Roger.

Apollo 13, Houston. You have a GO orbit all sources, and the booster is safe. Over.

GO orbit and the booster is safe. Thank you, Joe.

Don't mention it.

13, Houston. We copy your NOUN 44.

Okay, Joe.

Apollo 13, Houston. Your preliminary orbit down here is 102.5 times 100.3, and everything is looking good.

Roger, Houston. And it looks good to be up here again.

I'll bet.

13, Houston. I have your Z torquing angles. You ready?

Jack is ready to copy, Joe.

Okay. It's plus 0.26. Over.

Okay, Joe. Plus 0.26.

Apollo 13, Houston.

Go ahead, Houston.

Okay. Couple minutes to LOS, Jim. Everything is looking real good. Your AOS time at Carnarvon will be 52:36, and we don't have too much of a handle on why the inboard cut off early except that it apparently was an engine problem and not a switch-select function. But we are certain that you'll be able to make TLI based on what we are looking at now.

Roger. There's nothing like an interesting launch.

That's right.

Apollo 13, Houston. Canary LOS in 30 seconds. Request COMMAND RESET, please.

Roger. COMMAND RESET coming on.

Thank you.

Apollo 13, Houston. Request LOW BIT RATE, please. Over.

Houston, how do you read 13?

13, Houston. Loud and clear.

Okay, Joe. Everything's going good. We're proceeding on the time line in good fashion. I've got a P52 done. I can give you the torquing angles.

I'm ready for them, Jack.

Okay. Use NOUN 26; stars 26 and 33. The star angle difference was all balls. NOUN 93: minus 067, minus all balls, plus 0.162. The time of torquing was 45 minutes 35 seconds.

Well, that sounds marginally acceptable.

For a new CMP, it ain't too bad.

Apollo 13, Houston. LOS Carnarvon in about 30 seconds. Honeysuckle on the hour, and verify your S-band is up for Honeysuckle. Over.

That's verified.

Roger.

And, Houston, we're beginning to see a beautiful sunrise here.
