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.
- Ronald Evans (CAPCOM)
-
Okay. Before we start here, request P00 and DATA, and we'll give you some vectors.
- Neil Armstrong (CDR)
-
Okay. And I understand you want us to do a P57 option 3 and then a P22, is that the general idea? Over.
- Ronald Evans (CAPCOM)
-
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.
- Ronald Evans (CAPCOM)
-
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.
- Ronald Evans (CAPCOM)
-
Tranquility Base, affirmative. Those are just the circuit breakers at that time.
- Ronald Evans (CAPCOM)
-
Tranquility Base, Houston. Did you get those two on the propulsion circuit breakers?
- Ronald Evans (CAPCOM)
-
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.
- Ronald Evans (CAPCOM)
-
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.
- Neil Armstrong (CDR)
-
Roger. DESCENT PROPELLANT FUEL VENT, OPEN; DESCENT PROPELLANT OXIDIZER VENT, OPEN; verify talkback gray.
- Ronald Evans (CAPCOM)
-
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.
- Ronald Evans (CAPCOM)
-
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
- Neil Armstrong (CDR)
-
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.
- Ronald Evans (CAPCOM)
-
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.
- Ronald Evans (CAPCOM)
-
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.
- Ronald Evans (CAPCOM)
-
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.
- Ronald Evans (CAPCOM)
-
Roger, Columbia. We'd like a CRYO stir in all four tanks and the standard 1 minute. Over.
- Buzz Aldrin (LMP)
-
Roger. ERROR RESET, and would you tell me when you're satisfied with the LGC self test?
- Michael Collins (CMP)
-
Roger. Stars 25 and 42; angle difference 5 balls; NOUN 93, plus 00165, plus 00186, minus 00039, time of torquing 121 15. Over.
- Ronald Evans (CAPCOM)
-
Tranquility Base, Houston. Request you go ahead and start the warmup on the rendezvous radar.
- Ronald Evans (CAPCOM)
-
Tranquility Base, Houston. Columbia will be overhead at 122 plus 22 plus 51. His LOS will be 29 35. Over.
- Neil Armstrong (CDR)
-
Houston, we'd like to check this on the tape meter against the AGS. We'll go back to altitude—altitude rates as soon as the rate starts to build up. Over.
- Neil Armstrong (CDR)
-
On second thought, since that will peg the range rate, I guess maybe we'd better not do that. And for this range that the AGS are showing now, 425 miles with a signal strength of 2.2. It looks like we ought to proceed on this. Over.
- Ronald Evans (CAPCOM)
-
Tranquility, affirmative, and we're saving it. We've got 4 so far, and it's looking good.
- Ronald Evans (CAPCOM)
-
Tranquility, Houston. Stand by on that now. We're getting the data now. We're checking on the VERB 83.
- Buzz Aldrin (LMP)
-
And we expect that we may lose lock when it passes overhead because of the MAX rate that the radar has.
- Ronald Evans (CAPCOM)
-
Roger. We had about 20 some points before you did that. And for your information, the reason the AGS is a little different there—The reason the AGS is a little different is because the K factor is a little bit wrong.
- Buzz Aldrin (LMP)
-
Has he already gone? Over. Okay. Okay. Has he already gone overhead, or do you want us to try and get in lock on again?
- Ronald Evans (CAPCOM)
-
Tranquility, affirmative. Try to lock on again, and you'll lose him at about 29 minutes and 35 seconds.
- Michael Collins (CMP)
-
I say I got five good marks. You got NOUN 49. When you get everything you need off the downlink, let me know.
- Michael Collins (CMP)
-
I'm staying in P22 here a second just to record the NOUN 89 and then over VERB 34.
- Ronald Evans (CAPCOM)
-
Roger. Request S BAND FUNCTION switch to RANGE. We're going to do some ranging on you. Also, I have an updated AGS K factor when you are ready to copy. Over.
- Michael Collins (CMP)
-
This is Columbia. Go ahead. And I'd like to know about this P52 coming up. Is that the one I just completed or do you want a pair of them back to back?
- Ronald Evans (CAPCOM)
-
Columbia, Houston. You do not need to do another P52 unless you want to. Break. And also, Columbia, when you get a chance, request BATT C and the PYRO readouts. Over.
Expand selection down Contract selection up - Michael Collins (CMP)
-
And a crew status report from Columbia. I figure I got about 5 hours' good sleep, although you guys probably know better than I do.
- Ronald Evans (CAPCOM)
-
Columbia, Houston. We've got a couple more vectors to send up to you. They'll be coming up shortly and then you can do the VERB 45 after you get those in. Over.
- Michael Collins (CMP)
-
Okay. That's fine. Just wanted to make sure that we're both in SYNC on the order.
- Ronald Evans (CAPCOM)
-
Columbia and Tranquility Base, this is Houston. In case you haven't noticed, the MSFN relay is not activated, so I can go ahead and relay anything if you want to talk directly.
- Neil Armstrong (CDR)
-
Coming … on schedule — showing red right now. We just put a VERB 77 in. I believe that there's … let me check here.
- Ronald Evans (CAPCOM)
-
Tranquility Base, Houston. We've got a lot of static down here. Could you say again?
- Neil Armstrong (CDR)
-
Roger. We have four out of eight circuit breaker talkbacks indicating red. We still have the circuit breakers out as of right now. I believe at this moment we have just entered VERB 77 on tape 3052 and are ready to proceed with the hot fire. Is it normal to have these four red flags? Over.
- Ronald Evans (CAPCOM)
-
Tranquility Base, Houston. We think that's okay. Go ahead and reset them and press on with the hot fire. Over.
- Ronald Evans (CAPCOM)
-
Columbia, Columbia, Houston. Request P00 and ACCEPT, and we'll send some state vectors up to you.
- Neil Armstrong (CDR)
-
Houston, Tranquility. I used Capella in the last sighting, and it's a good ways near the edge. A good ways away from the center of detent 4. I'm wondering if it would pay any to use Alpheratz, star number 1. It might be a little closer. However, it would delay things a little, since I'd have to designate the radar out of the way. Over.
- Ronald Evans (CAPCOM)
-
Tranquility. Roger. We copy. Stand by 1. And, break, break, Columbia. We're having a little trouble getting the stuff in there. Request high gain, pitch minus 20, yaw plus 150. Over.
- Ronald Evans (CAPCOM)
-
And, Tranquility, Houston. We'd prefer to save the time; press on with Capella. Over.
- Buzz Aldrin (LMP)
-
Houston, Tranquility. Could you give me the fixed portion of the ascent PAD so I can load it in for a P57? Over.
- Ronald Evans (CAPCOM)
-
Tranquility. Roger. Stand by one. We want to wait on that P57 until about TIG minus 50 minutes. Over.
- Buzz Aldrin (LMP)
-
Houston, Tranquility. It turns out that detent 4 isn't usable anyway with the yaw that we have, because the Earth appears in both detent 2 and detent 3.
