Spacelog Apollo 11

Yes. I gather it's on its 24 minute warmup now?

Roger.

And, Houston. The computer is yours, you can go to BLOCK anytime.

Roger. BLOCK, going P52, option 3.

Roger. And we'll see you coming around the other side. About 1 minute to go, and all your systems are looking good.

Tranquility Base, Tranquility Base, Houston. Over.

Good morning, Houston. Tranquility Base. Over.

Roger. Loud and clear. And how is the resting standing up there. Did you get a chance to curl up on the engine can?

Roger. Neil has rigged himself a really good hammock with a waste tether, and he's been lying on the ascent engine cover, and I curled up on the floor. Over.

Roger. Copy, Buzz. Got a couple of changes to your surface checklist here, and in general, what we're going to want you to do is P22, tracking the command module for one last hack on your position there. And this will be—in other words, P57, P22, and then to press on with the checklist, and the rest of them are a couple of minor changes in the checklist. The main one being that we do not want the rendezvous radar on during the ascent, and we think that this will take care of some of the overflow of program alarms which we're getting during descent.

Okay. We had the rendezvous radar in SLEW during descent, though.

Tranquility Base, Houston. I missed that. Say again.

Roger. I say again. We had the rendezvous radar switch in the SLEW position, not the LGC position.

Roger. We copy that. But there's a greater duty cycle on—There's a good 15 percent duty cycle on the ascent program there, so just go ahead and leave it off. And I have the changes there if you want to get out your surface checklist, and I can go ahead and start giving them to you.

All right. Go ahead. I've got it out.

Okay. Before we start here, request P00 and DATA, and we'll give you some vectors.

Now you've got P00 and DATA.

Okay. And on Surface 50 will be the first change there.

Okay. And I understand you want us to do a P57 option 3 and then a P22, is that the general idea? Over.

That's affirmative. So on Surface 50 there, down at the bottom of the page, just after PRO after two recycles, stick in a time of 122 plus 15; do P22 as per PGNS 20 of G&N dictionary. Over.

Roger. Understand that's 122 15, do P22 as per PGNS 20, G&N dictionary.

Roger. Okay. Let's skip on over to Surface 59.

Okay.

Okay. This is going to be for one last vent on the DPS tank there, so at the top of the page just after EPS INVERTER 1, CLOSE, add—Okay, after EPS INVERTER 1, CLOSE, add PROP DESCENT HELIUM REG/VENT CLOSE, and then after STABILIZATION/CONTROL AELD, CLOSE, add PROP DISPLAYS/ENGINE OVERRIDE/LOGIC, CLOSE. Over.

Roger. Copy. These are two circuit breakers, right?

Tranquility Base, affirmative. Those are just the circuit breakers at that time.

Tranquility Base, Houston. Did you get those two on the propulsion circuit breakers?

Roger. I have those two.

Okay. Let's go over to Surface 60, and then down the middle of the page, after launch guidance system recommendation from MSFN, then I add the switches there.

Roger. Go ahead then.

Okay. After launch guidance system recommendation from MSFN, add DESCENT PROPULSION FUEL VENT, OPEN; add DESCENT PROPULSION OXIDIZER VENT, OPEN; add verify talkback gray. Over.

Roger. DESCENT PROPELLANT FUEL VENT, OPEN; DESCENT PROPELLANT OXIDIZER VENT, OPEN; verify talkback gray.

Roger. You got that one, so that'll be the last vent and it will continue venting. Skip over to Surface 61 down there at TIG minus 17.

Roger. I'm there. Go ahead.

Okay, at TIG minus 17, delete CB (11). AC Bus A, RENDEZVOUS RADAR, CLOSE, wait 30 seconds; delete PGNS: RENDEZVOUS RADAR, CLOSE; and then add UP DATA LINK switch to VOICE BACKUP. Over

Roger. I have that. We'll leave those two circuit breakers open, and have the UP DATA LINK to VOICE BACKUP; and we'll make the appropriate changes on the following circuit breaker status card.

Roger. And then you might add a little note down there at the bottom of the page—Note:—This is at the bottom of page 61—Note: Do not use tape meter in PGNS, i.e., do not place MODE SELECT switch to PGNS. Over.

Okay. We'll put it in AGS.

Roger. Fair enough. That's some more of that computer load business.

Okay. That's all the changes we have for the checklist here. I've got some—just some general notes, I'll read to you on P22, and just for some information. Over.

Okay. Then it looks to me like we ought to get hopping on this P57.

Roger. We agree wholeheartedly. And while you're starting on that, I'll read—just read these notes on P22. Call P22 possible program alarm 5.6, range greater than 400 nautical miles, and then use the P22 as described on PGNS 20. Take option 1 in NOUN 06, and use the no update mode. The rendezvous radar will lock on at about 25 degrees elevation above the horizon. If 503 alarm occurs, designate fail. Key a PROCEED and allow the rendezvous radar to search for the CSM. And place the range altitude monitor switch in altitude/altitude rate to prevent the tape meter from driving into the stops. And press on.

Columbia, Columbia, Houston. Over.

Columbia, Columbia, Houston. Over.

Houston, Columbia.

Roger, Columbia. We'd like a CRYO stir in all four tanks and the standard 1 minute. Over.

In work.

Roger. And do you have any torquing angles from the P52?

Roger. Stand by one.

Tranquility, Houston. Request ERROR RESET at this time. Over.

Roger. ERROR RESET, and would you tell me when you're satisfied with the LGC self test?

Tranquility, LGC is a GO.

Roger.

Torquing angles when you're ready.

Columbia, Houston. Go ahead.

Roger. Stars 25 and 42; angle difference 5 balls; NOUN 93, plus 00165, plus 00186, minus 00039, time of torquing 121 15. Over.

Columbia, Houston. We copy. Thank you.

And CRYO stir complete.

Houston, Tranquility. Would you like a recycle on the VERB 6 04? Over.

Tranquility, Houston, We copy. Stand by one.

Houston, Columbia. My rendezvous radar transponder is operating.

Spacecraft calling Houston? Say again.

This is Columbia saying the rendezvous radar transponder is operating.

Roger. Copy, Columbia.

Tranquility, Houston. Request rendezvous radar breakers in about now.
