Buzz Aldrin (LMP)

Houston, Apollo 11. I'd say that the secondary loop was actuated about 15 to 20 minutes ago. Over.

Charlie Duke (CAPCOM)

Roger. Copy. Columbia. Thank you very much.

Charlie Duke (CAPCOM)

Columbia, Houston. It looks like you guys are so speedy on us that we're thinking about moving up jettison time to about a GET of 130 plus 30, if that's okay with you all. Over.

Michael Collins (CMP)

That's fine. I've still got to get a P30 PAD from you.

Charlie Duke (CAPCOM)

Roger. We want to talk to you about that. Mike, we can—for your druthers, we can do it either way. We can either let you do it in the jettison in P30—correction P47, or we can send you a P30 target load up and then you—let you call P41, whichever you want to do. Over.

Michael Collins (CMP)

Yes, I see. Ron was going to give me a P30 PAD and the flight plan says P47. Out of the two, I prefer to go to P30, P41 route.

Charlie Duke (CAPCOM)

Roger. Beautiful. We've got the load. If you'll give us P00 and ACCEPT, we'll send you a load up. Stand by.

Charlie Duke (CAPCOM)

Columbia, Houston. We'd like you to terminate direct O2 flow, and stand by on your P00 and ACCEPT. We'll have to generate a new load due to the moveup on time. Over.

Charlie Duke (CAPCOM)

Columbia, Houston. Over.

Charlie Duke (CAPCOM)

Roger, Mike. It looks like if we move up this jettison time and give you a new load, it would require a new attitude, and we can't do that due to the LM already closed out, and it would fight us all the way around and we'd lose COMM with it. We're thinking separating in P47 in about 10 minutes. We're looking at trajectories and we'll be right with you momentarily. Over.

Michael Collins (CMP)

Okay. It's no big thing with me either way.

Charlie Duke (CAPCOM)

Hello, Columbia. Houston. We'd like you to start down your jettison checklist. We recommend picking up page F11—12 and we'd like to jettison at 10 minutes. That'll be 130 14 15. Over.

Charlie Duke (CAPCOM)

Columbia, Houston. If that's not satisfactory, let us know. Over.

Neil Armstrong (CDR)

Houston, Columbia. How about a GO for logic BUS ARM.

Charlie Duke (CAPCOM)

Columbia, Houston. You've got a GO.

Charlie Duke (CAPCOM)

Columbia, Houston. You can undock at your convenience, correction, jettison at your convenience. We would like you to jettison Eagle and stationkeep—in P47 and stationkeep, and we'll have another attitude and a maneuver for you so we'll be okay for TEI. Over.

Michael Collins (CMP)

And I'm standing by to go to P47 just as soon as you give me a go for PYRO ARM.

Charlie Duke (CAPCOM)

Roger. I thought we gave you that. Mike, you're GO for PYRO ARM and you're GO for jettison.

Michael Collins (CMP)

Okay. Let her go in 10 seconds.

Michael Collins (CMP)

NOUN 83 reading minus four balls, minus three balls, 3 or—correction—minus—both register 1 and register 2 are reading minus four balls 3, register 3 is zeros, the EMS remained on 100.00. A fairly loud noise, and it appears to be departing—oh, I would guess several feet per second.

Charlie Duke (CAPCOM)

Roger, can you kind of stationkeep with it, Mike? Just stand by now.

Charlie Duke (CAPCOM)

Columbia, Houston. Don't try to chase it, just hold what you've got.

Buzz Aldrin (LMP)

Charlie, did it hold cabin pressure this time?

Buzz Aldrin (LMP)

Okay. I thrusted back—I thrusted back toward it a little bit, Charlie, and I'm now reading NOUN 83, plus four balls 4, minus four balls 8, and you want me to kill average D. Right?

Charlie Duke (CAPCOM)

Stand by. That's affirmative. You can exit P47.

Charlie Duke (CAPCOM)

Roger dodger. We got Eagle looking good. It's holding cabin pressure and it picked up about 2 feet per second from that jettison.

Buzz Aldrin (LMP)

I believe that. I can see some cracks on the outer coating around the tunnel. In the thermal protective covering, I don't think it has anything to do with the structure.

Charlie Duke (CAPCOM)

Hello, Columbia, Houston. We'll have an attitude and a little blip burn for you in about 130 30, so we can separate from Eagle. Over.

Charlie Duke (CAPCOM)

Columbia, Houston. Would you start a maneuver to a pitch of 230 for this little tweak burn? Over.

Charlie Duke (CAPCOM)

Roger, Mike. And verify track mode in AUTO for the high gain.

Michael Collins (CMP)

We're in REACQ. Is that all right?

Charlie Duke (CAPCOM)

Say again. We need AUTO.

Michael Collins (CMP)

Say again. We're in REACQ—AUTO REACQ.

Charlie Duke (CAPCOM)

Roger. We need AUTO, please, sir.

Michael Collins (CMP)

Roll zero, pitch 320, yaw zero?

Charlie Duke (CAPCOM)

Right now that's what we're looking at. Stand by. We might have you roll so we can keep the high gain. Stand by.

Charlie Duke (CAPCOM)

Columbia, Houston. Over.

Charlie Duke (CAPCOM)

Oh, Roger, Apollo 11. We got you going to a posigrade attitude and we want you—this burn will be using minus X thrusters at about 2 or 3 feet per second, and we got a load for you. We'll send it up momentarily. Over.

Michael Collins (CMP)

Okay.

Charlie Duke (CAPCOM)

Apollo 11, Houston. Would you give us P00 and ACCEPT? We have a load for you. Over.

Charlie Duke (CAPCOM)

Roger, Mike. And our pitch attitude's a little wrong here. If you're ready to copy, I'll give you the SEP PAD. Over.

Michael Collins (CMP)

Go ahead. Ready to copy.

Charlie Duke (CAPCOM)

Roger. Starting with NOUN 33: 130 30 0000, plus 00020, plus all zeros, plus all zeros. Roll all zeros, pitch 230, yaw zero. NOUN 44 is NA. DELTA-VP 00020, burn time 007, DELTA-VC 00020. We have—The rest of the PAD is NA.

Michael Collins (CMP)

Roger. GET 130 hours 30 minutes, DELTA-VX 2.0, roll zero, pitch 230, yaw zero, DELTA-VC, 2.0.

Charlie Duke (CAPCOM)

That's affirmative, Apollo 11. And, Mike, it's similar to the SEP burn prior to flight after the undocking here. And the P41 you should see on register 1—2, and then you burn minus X until you read 4. Over.

Charlie Duke (CAPCOM)

Apollo 11, Houston. Computer's yours. Over.

Michael Collins (CMP)

Roger, Charlie. We switched our OMNI D—Delta, and I lost that last transmission. Would you say again, please? The thing I'm wondering about specifically is that earlier you said it would be minus X thrusters and the PAD indicates plus X. Do you want me to null that to zero or do you want to add 2 and leave it as a 4?

Charlie Duke (CAPCOM)

Roger, Apollo 11. The way we gave it to you in the attitude we're in, it'll be just like the SEP burn that you had yesterday. You'll see—NOUN 85 will give you a plus 2 and then you just burn minus X until you read 4. Over.

Charlie Duke (CAPCOM)

Apollo 11, Houston. We see you in P41 now. It might take you a couple of minutes to integrate these vectors that we gave you and if you don't make TIG, it's pretty insensitive. You can just let P41 bring you up to TIG, and when you get to zero, you can burn on that. Over.

Michael Collins (CMP)

Okay. Burn complete. Residuals: plus three balls 40, plus four balls 7, plus four balls 2, DELTA-V counter 102.1. Over.

Charlie Duke (CAPCOM)

Copy, Apollo 11. Looks good to us. Over.

Michael Collins (CMP)

Houston, Apollo 11. How about coming up with a good communications attitude for us to go to between now and the time we maneuver at TEI attitude.

Charlie Duke (CAPCOM)

Hello, Apollo 11, Houston. A couple of things for you. Over.

Charlie Duke (CAPCOM)

Okay. Mike, you can maneuver to your preliminary TEI attitude as shown on page 398 of the flight plan, and the high gain angles are good as shown in the flight plan, and we'd like you to dump the waste water at 131 05 down to 10 percent. Over.

Michael Collins (CMP)

Okay. Understand. I'm going to go to roll 1.1, pitch zero—or 52.6, and yaw 13.8, and you want a waste water dump 10 percent starting at 131 05.

Charlie Duke (CAPCOM)

That's affirmative. Right out the LOS.

Michael Collins (CMP)

Maneuver is in progress, Houston.

Charlie Duke (CAPCOM)

Apollo 11, Houston. Over.

Michael Collins (CMP)

Apollo 11 under high gain. How do you read?

Charlie Duke (CAPCOM)

Five by, 11. How me? Over.

Michael Collins (CMP)

You're loud and clear, Charlie. What—What numbers are you looking at for TEI TIG preliminary; 135 hours 23 minutes, something like that?

Charlie Duke (CAPCOM)

That's affirmative, Mike. We're looking at about nominal time. We've considered kicking it up a REV, but we don't think this REV track is going to be any good since we had the RCS burn and we need some more tracking to get you a good TEI. Over.

Michael Collins (CMP)

That's what we're looking for.

Charlie Duke (CAPCOM)

11, Houston. Looks like it's going to be pretty relaxed time here for the next couple of hours. We'll have you a PAD, of course, the next REV or so, and we'll keep you posted on TEI. Looks like nominal time. Over.

Charlie Duke (CAPCOM)

And your little maneuver back here a moment ago will put you about 20 miles ahead of the LM at TEI.

Michael Collins (CMP)

Imagine that place has cleared out a little bit after that rendezvous. You can find a place to sit down almost, huh?

Charlie Duke (CAPCOM)

Roger. Our MOCR's about empty right now. We're taking it a little easy. How does it feel up there to have some company?

Michael Collins (CMP)

Damn good, I'll tell you.
