Spacelog Apollo 11

Roger. Standing by.

Okay, I'm ready to copy.

Okay, Ron, For MIDPAC: 000, 152, 001, 194, 46 06, 267, plus 1332, minus 16917, 064, 36194, 649, 14045, 36275, 195 03 06, 0028, 154, 084, 2240, 180, 400, 02 13, 00 17, 03 51, 09 02, 45, 0189, 277, none available, lift vector up, GDC align, Vega and Deneb, roll 078, pitch 223, yaw 340. Use nonexit EMS. EI minus 30, horizon check 194 33 06, pitch 298. Initial bank angle in P67 may not be full lift, and we will get P65 but no P66.

Apollo 11, Houston. Roger. On your GDC align pitch, it should be 233, 233 in the pitch. Over.

Okay. I've got a 233.

Also your DL and MAX and MIN, I'm sure. are 22 400 and 18 000. Over.

Yes. That's right.

Okay. If you'll dig out your entry checklist there on page E6 1, I'll update your RETRO times there for the various altitudes. Over.

Okay. Go ahead.

Okay. On page E6 1, your RRT is 07 20, your 50K is 08 16; 40K is 08 30; your 24K is 09 02; and your 10K is 09 51. Over.

Okay. RRT, 07 20, 50 000, 08 16. That's—07 20 is—is the time of steam pressure peg from RRT; and 40 000, 08 30; 24 000, 09 02; 10 000, 09 51.

11, Houston. You started out right, and then the numbers you read back were correct; but I didn't get your comment in between there.

I assume that—all I wanted to know is that first time, 07 20, that's the time of steam pressure peg. Right?

That's affirmative.

Houston, Apollo 11. Ron, I'm ready to copy your message about the constant drag level.

Okay, Mike. Of course, this is in the event the G&N and the EMS quits and you have to fly the constant g; and what we're trying to do is extend the constant g range from 1100 to 1500 miles. We've run this procedure in the simulator, and it works fine. Basically, I'll go through it—just go through it, and then if you have any questions come back. But it's the same lift vector up until MAX g, and then lift vector down, and then modulate the lift vector until g dot goes to zero. Okay. This procedure is essentially the same so far. And then hold g dot zero until you pass the RETRO elapsed time of V circular; and then after you pass this RETRO elapsed time of V circular, roll to a gimbal angle of 45 degrees, and then hold this constant bank angle of 45 degrees until you come to the RETRO elapsed time of drogues. Over.

Okay. It sounds straightforward enough. Understand constant g backup backup procedure, lift vector up until MAX g and then lift vector down; then modulate until bank angle until g dot equals zero. Maintain g dot equals zero until subcircular, then roll 45 degrees and hold until drogue time. Over.

Okay. That's mighty fine, Mike. That's correct.

This entry time line is my kind of time line. Nice and slow.

Okay, 11. Houston. Roger. It sure is. EECOMM is anxiously awaiting his big moment here for the logic sequence check whenever you're ready.

Okay. We'll be ready for that in just a flash.

Roger.

Apollo 11, Houston.

Go ahead, Ron.

This is Jim, Mike. Backup crew is still standing by. I just want to remind you that the most difficult part of your mission is going to be after recovery.

Well, we're looking forward to all parts of it.

Please don't sneeze.

Keep the mice healthy.

The Earth is really getting bigger up here and, of course, we see a crescent.

Yes.

Houston, Apollo 11. We're ready for the logic check whenever you are. We're standing by to arm the logic. We've got ELS logic on, ELS AUTO, and all the circuit breakers in.

Apollo 11, Houston. Roger. You can press on with the SECS logic.

Okay. Logic 1 coming on.

MARK it.

Logic 2 coming on.

MARK it.

Apollo 11, Houston. Logic checks good. You're GO for PYRO ARM.

Thank you, sir.

Houston, Apollo 11 has got VHF A Simplex on whenever you want to make a COMM check.

Apollo 11, Houston. Roger. You faded out a little bit there, Buzz. I understand you have the VHF Simplex A on now. Is that correct? Over.

That affirmative. VHF Simplex A and we're TR on VHF.

Roger. Mighty fine. We'll watch it as you are coming on in and let you know when the intelligibility is up. We'll make a voice check with you at that time.

Houston, Apollo 11. I've been holding here in SCS control MINIMUM DEADBAND RATE LOW with the limit cycle on, just as a matter of curiosity, if you guys wanted some fuel numbers from that.

Go ahead.

Roger. Just to get a little downlink here to check out our VHF: I show us about an hour and 37 minutes, approximately, from entry interface. Over.

Okay. That's about right.

Okay. Looks like we're together on that, and I guess we're standing by for you to whip into the entry attitude.

Okay. We've just been taking a couple of last minute pictures. We've finished the EMS entry check, primary water EVAP activation.

Apollo 11, Houston.

Go ahead.

Roger, Mike. We recommend the left VHF antenna for VHF.

And this is your friendly backup CMP. Have a good trip, and may—remember to come in BEF.

You better believe. Thank you kindly.

We can see the Moon passing by the window and it looks what I considered to be a correct size.

Houston, Apollo 11. Like to switch to S band OMNI C. I just did a minute ago, and noticed a loss of signal strength, over.

Roger, Apollo 11. Go ahead and try it again now that you're in attitude.

Apollo 11, Houston.

Apollo 11, Houston.

Go ahead, Ron.

Roger. Faces are red here. We lost data with you there for a while. Did you do the P52? Over.

That's affirmative, we completed the P52. We'll give you the data from it in just a second. We passed our sextant star check at entry attitude, and right now we're maneuvering to our first horizon check pitch attitude of 298 degrees.

Apollo 11, Houston. About 4 minutes to 1 hour, and I'll give you a mark at 1 hour. Was a command module preheat necessary? Over.

Negative that.

Apollo 11, Houston.

Go ahead.

Roger. We don't want to jettison the hydrogen tank that stratified, so could you cycle the fans in tank 2 please? Hydrogen tank 2.

You better believe, that old service module has taken good care of us. We want to take good care of it.

It sure has, hasn't it.

11, Houston. I'll give you a time hack at 58 minutes to go. It's about 15 seconds yet.

Thank you.

Stand by.

MARK.

58 minutes.

Apollo 11, Houston.

Go ahead, Houston. Apollo 11.

Roger. We have our update at the state vector out there for you. Request P00 and ACCEPT. Over.

Okay. You've got it.

Okay. Here it comes.

Apollo 11, Houston.

Go ahead.
