Spacelog Apollo 11

Columbia, Columbia, good morning from Houston.

Hi, Ron.

Hey, Mike, how's it going this morning?

How goes it?

Hey, real fine. While you're —

I don't know yet, how's it going with you?

Real fine here. Columbia, request P00 and ACCEPT. We'll shove the state vector in for you right away.

Okay. It's coming up now, Columbia. We're going to keep you a little busy here. As soon as we get the state vector in, we'd like you to go ahead and do a P52 option 3 on this night pass, and then when you come on around the other side there, we'll give you some landmark tracking information on prime 130.

Okay.

And for your information, we're also going to have Tranquility Base do a P52 when you come around the other time; and I have the P22 information if you're ready to copy.

Go ahead.

Okay. Track landmark 130 prime using P22, and for information, this will properly position your rendezvous radar transponder. T1 is 122 plus 16 plus 05—whoops, okay. Stand by.

Columbia, Houston. The computer is yours.

Okay. And I'd like the grid square of this crater 130 prime. Over.

Columbia, Houston. Say again about 130 prime.

I'd like its grid square, please.

Columbia, Houston.

Go ahead.

Roger. I have the T1 and T2 times and also the longitude of the 130 prime. We're working on the grid squares and we'll get them shortly.

Okay. Ready to copy.

Okay. T1: 122 plus 16 plus 05. Tango 2 is 122 plus 21 plus 11, and 6 miles north of track. And do you want your NOUN 89 values?

Yes, please.

Roger. Latitudes, plus 01.243. Longitude over 2, plus 11.844. Altitude, minus 001.46. Over.

Copy T1: 122 16 05. T2: 122 21 11, 6 miles north, NOUN 89 is plus 01243, plus 11844, minus 00146.

Columbia, affirmative. And at the T1 time, put your rendezvous radar transponder switch to OPERATE.

All right.

And this 130 prime is the same one that you tracked prior to descent. Over.

Okay. You've updated your information as to the LM's position and this is your best estimate of where the LM is, is that correct?

Columbia, that's negative. This 130 is the little bitty crater there that you tracked—John Young's crater—that you tracked prior to descent. And we want that —

Fine. Okay. You've given up looking for that.

Affirmative. We want this for one last fix on your plane.

All right. Fine. Understand. Thank you.

And when the LM does his P22 on your transponder, well then, that'll be our last shot at the LM's position.

Roger. Understand. Do you care whether my transponder is on before T1?

Roger. It'll be on WARMUP prior to that time, and you can go to OPERATE anywhere around that time.

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.
