Spacelog Apollo 13

Okay. TLI: 2 plus 26 plus 05, 179, 108, 000, 5 plus 47, 10416.9, 35587, 358, 139, 320, 302, 319, 040, and ejection time, 4 plus 01 plus 00.

Apollo 13, Houston. We've had LOS MILA now. Thank you very much.

Apollo 13, Houston. Request P00 and ACCEPT for a state vector. Over.

Roger, Houston. We're in P00 and ACCEPT.

Apollo 13, Houston.

Go ahead, Houston.

Okay. The computer is yours, Jim.

Thank you, —

And you are GO for TLI. Huntsville reports that you have a 6-second propellant pad which is 3 seconds more than a 3-sigma case; so you're good on consumables. The IU is so good that we're not going to update it. The only change we have for you is in the TLI checklist. At 57 minutes where you slew the FDAI to 18 degrees, we recommend 20 degrees there, and we recommend that you look for 8 degrees instead of 6 degrees at ignition. The S-IVB is riding on the top of its deadband.

— Understand; and just out of curiosity, was that engine out to use up more S-IVB fuel?

The engine out did cause you to use more S-IVB fuel—about a 10-second-longer burn; but you're still GO.

Okay. Thank you.

And, 13, Houston. We're ready to support pyro arm and docking probe extension whenever you're ready.

Okay, Houston. Docking probe has been extended and all indications are nominal. We're down to PYRO ARM now and we're getting ready.

Okay, Jim.

Okay, Houston. My circuit breaker's armed—or closed; SEQUENTIAL LOGIC, two, on and up and we're …

Okay, 13. You are GO for pyro arm.

And, Houston, 13. Were you reading us?

Roger, 13. Go ahead.

Roger. We have our SEQUENTIAL ARM circuit breakers in and our SEQUENTIAL LOGIC, two, on and up and we are just standing by for your confirmation for a GO.

Sorry, 13. You didn't copy. You are GO for pyro arm. Over.

Apollo 13, Houston.

Go ahead, Houston.

About 2-1/2 minutes to LOS, Jim, and your AOS at Carnarvon will be 2 plus 25 plus 50. Over.

Roger. AOS at Carnarvon 2 plus 25 plus 50.

That's affirm.

Apollo 13, Houston. LOS in about 1 minute. At LOS we would like COMMAND RESET and then NORMAL.

Apollo 13, Houston through Carnarvon.

Okay, Joe. Read you loud and clear. We are sitting here monitoring time base 6 … countdown; we're 20 seconds away.

Okay. We're just starting to get data, and everything still looks good to us.

Hey, Joe. At 2 hours and 12 minutes, the O₂ FLOW HIGH light came on, and it's been pegged high ever since, so it's been on about 14 minutes now.

Roger, 13. We're looking at it.

Time base 6.

Copy. Time base 6.

Okay. Apollo 13, Houston. You have a GO for all systems, and the O₂ FLOW HIGH check is nominal with the WASTE TANK VENT open at this time, and it's no sweat.

Okay. Just wanted you all to check it for me.

Apollo 13, Houston through Hawaii. Over.

13 through Hawaii. How do you read?

13, Houston. You're weak but clear; it will probably get better in a second. We're standing by for the burn report.

Roger.

13, Houston. The booster reports that everything looks good with the S-IV.

Sounds good, Houston. The ride was very nominal. We a little vibration, though, during most of the run.

Okay. We copied your call on that, Jim.

Okay, Joe. the DSKY read 35560, plus 04445, plus 01769, and DELTA-V_C was minus 3.0.

Roger. You can't ask for much better than that. How about the burn time? Did you notice?

Okay. On my trusty watch, I had about 3-3/4 seconds long.

Okay. Copy that.

Apollo 13, Houston.

Roger, Houston; 13 here.

Okay. We have the S-IVB maneuver to SEP attitude commencing at 2 plus 56 plus 37. Duration of the maneuver: 4 minutes. SEP time, 3 plus 06 plus 37. Over.

Okay. If I heard those right, Joe, the S-IVB maneuver was 2 plus 56 plus 57. SEP time is 3 plus 06 plus 27.

Correction on the second; 2 plus 56 plus 37, and 3 plus 06 plus 37.

Okay. 2 plus 56 plus 37, with the maneuver time and the SEP time, 3 plus 06 plus 27?

That's plus 37, too. Exactly 10 minutes later, Fred.

Apollo 13, Houston.

Go ahead.

We see the booster doing all the right things, and FIDO says your trajectory looks good, and it looks like we'll stick with a pretty close to nominal midcourse, too. We'll have some numbers for you later.

Okay. And we concur. The S-IVB is maneuvering at this time.

Roger.

And, Apollo 13, Houston. We'd like OMNI Alfa. Over.

13, Houston. Now request OMNI Charlie.

Roger. OMNI Charlie.

And, 13, we'll be doing a handover, now.

Okay.

Apollo 13, Houston. You are GO for T&D.

Okay, Joe. Thank you.

And, 13, Houston. Check your NOUN 17 for extraction pitch attitude. It should be 319 degrees. Over.

Okay, Houston; 13. Do we have a GO for pyro arm?

13, Houston. Affirmative. You're GO for pyro arm, and recommend you secure the cabin pressurization.

We did. We closed the waste management vent valve, there. Or waste stowage valves —

Okay. We're reading 6 psi on the cabin, Jack.

Roger, Joe. Thank you very much.

Yes, that's quite a bang, Joe. We've separated, and we've pitched around about 60 degrees now.

Roger, Jack. We see you pitching.

Okay. We got the SLA panels—one of them is out front now.

Ah, so.

Got the S-IVB. I guess we're about 80 feet.

Good deal.

Okay. I'm going to come on with the TV now, Joe.

Okay, Fred. We're waiting for it.
