Ronald Evans (CAPCOM)

Eagle, Houston. Aft OMNI, low bit rate, an we'll see you at 127 plus 51.

Ronald Evans (CAPCOM)

Eagle and Columbia, Houston. Standing by.

Neil Armstrong (CDR)

Roger. We're stationkeeping.

Neil Armstrong (CDR)

Okay, Mike. I'll get—try to get in position here, then you got it.

Neil Armstrong (CDR)

How does the roll attitude look?

Neil Armstrong (CDR)

I'll stop. Matter of fact, I can stop right here if you like that.

Ronald Evans (CAPCOM)

Eagle, Houston. Middle gimbal. And you might pass to Columbia, we don't have him yet.

Neil Armstrong (CDR)

Key moment Eagle meets up with Columbia in lunar orbit: I'm not going to do a thing, Mike. I'm just letting her hold in ATTITUDE HOLD.

Neil Armstrong (CDR)

Okay. We're all yours. Roger.

Michael Collins (CMP)

Okay. Okay, I have thrusters B3 and C4 safetied.

Michael Collins (CMP)

I'm pumping up cabin pressure.

Michael Collins (CMP)

That was a funny one. You know, I didn't feel it shock, and I thought things were pretty steady. I went to RETRACT there, and that's when all hell broke loose. Were you guys—did it appear to you to be—that you were jerking around quite a bit during the retrack cycle?

Neil Armstrong (CDR)

Yes. It seemed to happen at the time I put the plus X thrust to it, and apparently it wasn't centered, because somehow or other I accidentally got off in attitude and then the attitude hold system started firing.

Michael Collins (CMP)

Yes. I was sure busy there for a couple of seconds.

Michael Collins (CMP)

Are you hearing me all right? I got a horrible squeal.

Expand selection up Contract selection down Close
Neil Armstrong (CDR)

Yes. I agree with that, but we hear you okay. Over.

Michael Collins (CMP)

Houston, Apollo 11. Over.

Michael Collins (CMP)

Roger. I'm supposed to adjust the oxygen flow in this thing to six tenths of a pound per hour, but being as how this transducer is not working right, could you give me an updated number?

Ronald Evans (CAPCOM)

Affirmative. You want to go ahead and adjust your O2 flow until it just goes off the peg, and then crank the direct O2 valve back down about 5 degrees. Over.

Michael Collins (CMP)

Boy, you were really waiting for that one, weren't you? Okay, Ron. Thank you.

Michael Collins (CMP)

Houston, I did that, and I believe we are flowing oxygen, but the gage is just pegged FULL SCALE LOW.

Ronald Evans (CAPCOM)

Roger. That's fine. That's what we expect.

Michael Collins (CMP)

Okay. I'm going to go ahead with the tunnel leak check.

Ronald Evans (CAPCOM)

Columbia, Houston. I have a new LM weight for you whenever you're ready to copy.

Michael Collins (CMP)

Not right now, Ron. Remind me of it later, would you please?

Michael Collins (CMP)

Houston, Apollo 11. I let P47 run longer than I should. I may have deteriorated our state vector slightly.

Ronald Evans (CAPCOM)

Roger, Apollo 11. That's okay. We'll see later.

Michael Collins (CMP)

Houston, Apollo 11. Go ahead with your DAP up, please.

Ronald Evans (CAPCOM)

Roger. Your LM weight, 5785. For an R1 we'd like to have 61102, R2 01111. Use BD roll. Over.

Michael Collins (CMP)

Roger. I'm configured now at … for BD roll, and I have thrusters C4 and B3 turned off, and I copy register 1 61102 01111 and LM weight 5785. Thank you.

Michael Collins (CMP)

Houston, Columbia has completed the leak check, and proceeding with opening the hatch dump valve.

Ronald Evans (CAPCOM)

Roger, Columbia. Understand you're doing the leak check. I missed anything after that.

Michael Collins (CMP)

I say the leak check is complete, and I'm proceeding with opening the hatch dump valve.

Ronald Evans (CAPCOM)

Eagle—Columbia, Roger.

Michael Collins (CMP)

My hatch is removed. You can open yours, and I'll start passing stuff up to you.

Michael Collins (CMP)

No. Stand by one, first.

Michael Collins (CMP)

Yes, everything is going fine. Be with you in just a second.

Buzz Aldrin (LMP)

Go ahead, Houston, Eagle here.

Ronald Evans (CAPCOM)

Roger. Any time prior to jettison there, we'd like an AGS to PGNS align: 400 plus 30 000. Over.

Buzz Aldrin (LMP)

Okay. Any particular attitude you would like the PGNS in when we do that?

Buzz Aldrin (LMP)

No. We're not getting any. Could you give us some course align gimbal angles to move the PGNS to, and then we will align the AGS to the PGNS. Over.

Ronald Evans (CAPCOM)

Roger. Eagle. We concur. Stand by on the gimbal angles. And also, Eagle, while we've got the command module direct O2 on there, there's a possibility that your cabin relief might relieve if we get up around cabin pressure of about 5.4 or 5.5.

Ronald Evans (CAPCOM)

Roger. All we are trying to do is get PGNS and AGS aligned together. Doesn't make any difference on the gimbal angle.

Buzz Aldrin (LMP)

Okay. We are pretty close to 000. Is that all right?

Ronald Evans (CAPCOM)

Eagle, that's beautiful.

Buzz Aldrin (LMP)

Now, you might want to take into account what will happen when the CSM maneuvers to jettison attitude.

Ronald Evans (CAPCOM)

Eagle, Houston. We don't care what—All we are trying to do is get a drift rate and see how long it takes them to drift apart on the thing after you jettison.

Buzz Aldrin (LMP)

Okay. Will we be jettisoning at about this attitude? That's okay. I'll align the AGS with the PGNS. You can tell me a little later if you need some help.

Ronald Evans (CAPCOM)

Eagle, Houston. That's fine.

Michael Collins (CMP)

Houston, Columbia. You want me to roll over and get high gain or anything like that?

Ronald Evans (CAPCOM)

Columbia, Houston. I can give you some REACQ angles for the high gain on the LM jettison attitude. Then you can go there whenever you want to. The angles are pitch minus 50, and yaw zero.

Michael Collins (CMP)

Houston, Columbia. Say again the jettison roll, pitch, and yaw, please.

Ronald Evans (CAPCOM)

Columbia, Houston. Roll zero, pitch 025, and yaw zero. Over.

Michael Collins (CMP)

Roger. Understand roll zero, pitch 025, yaw zero.

Michael Collins (CMP)

… in progress. We've moving. Houston.

Buzz Aldrin (LMP)

Roger. It doesn't appear as though the red hose is going to be much of a competitor to the leading vacuum cleaner brands. Over.

Ronald Evans (CAPCOM)

There's a little noise there, Buzz. Say again.

Ronald Evans (CAPCOM)

Roger. Just a reminder to be sure to zero the AGS errors before you enable the AGS attitude hold there after you get in burn attitude.

Buzz Aldrin (LMP)

Roger. You mean SEP attitude?

Michael Collins (CMP)

Houston, how do you read Columbia on high gain now?

Ronald Evans (CAPCOM)

Hey, Columbia. Houston. Mighty fine; loud and clear.

Ronald Evans (CAPCOM)

And Eagle, Houston. Your steerable antenna angles for jettison attitude are—Over.

Ronald Evans (CAPCOM)

Roger. Pitch 165, yaw 68. Over.

Neil Armstrong (CDR)

Roger. Pitch 165, yaw 68.

Ronald Evans (CAPCOM)

Eagle, Houston. Correct.

Ronald Evans (CAPCOM)

Roger, Mike. You want to tweak the O2 flow up just a bit there?

Michael Collins (CMP)

Okay. Coming up. Houston, do you have any preferences as to what you want us to do with the probe? Over.

Ronald Evans (CAPCOM)

Columbia, Houston. Stand by one.

Michael Collins (CMP)

Okay. Eagle says they've got a place for it inside there, so no problem.

Ronald Evans (CAPCOM)

Roger. That's all we were assuming.

Ronald Evans (CAPCOM)

Roger. Neil, it looks like your steerable's good. You can put your track mode to slew and high bit rate, please. Over.

Neil Armstrong (CDR)

Okay. Track mode to slew and high bit rate.

Michael Collins (CMP)

Okay. Stand by just one, please.

Michael Collins (CMP)

Okay. Shoot them on down.

Ronald Evans (CAPCOM)

Roger. Neil, just a reminder again, the ACA out of detent to zero; the AGS out of there just in case you go to ATTITUDE HOLD shortly.

Michael Collins (CMP)

You say you wanted the probe now?

Neil Armstrong (CDR)

Houston, Eagle. Go ahead.

Ronald Evans (CAPCOM)

Roger. That ACA out of detent didn't quite do it because the mode control switches were off. Request guidance control to PGNS and then back to AGS, and that will zero the AGS, there. Over.

Ronald Evans (CAPCOM)

Roger. Request guidance control switch to PGNS and then back to AGS. Over.

Neil Armstrong (CDR)

Okay. We still have both mode control switches off. Over.

Ronald Evans (CAPCOM)

That's okay. That's good.

Neil Armstrong (CDR)

And I thought I'd just take about 5 seconds here and see if I could get 000 gone, since we're fairly close to gimbal lock right now.

Ronald Evans (CAPCOM)

Eagle, Houston. That's fine.

Ronald Evans (CAPCOM)

Columbia and Eagle, Houston. About 5 minutes to LOS. Your LM jet time will be 131 plus 52, and I have the rest of the maneuver PAD if you want it now, or I can give it to you on the next time around.

Michael Collins (CMP)

Could you read it around the next time around, please?

Ronald Evans (CAPCOM)

Sure, Mike. That's fine. We'll get it to you then.

Ronald Evans (CAPCOM)

Apollo 11, Houston. About a minute and a half to LOS. You're looking great. It's been a mighty fine day.

Michael Collins (CMP)

Boy, you're not kidding.

Charlie Duke (CAPCOM)

Hello, Eagle. Houston. Do you read? Over.

Neil Armstrong (CDR)

Houston, this is Columbia. Reading you loud and clear. We're all three back inside; the hatch is installed. We're running a pressure check leak check. Everything's going well.

Charlie Duke (CAPCOM)

Roger, Eagle. Correction—Roger, Columbia. We copy. You guys are speedy; you beat us to the punch. We had a couple of things for you.

Charlie Duke (CAPCOM)

Oh, it was just—We wanted you to close the CO2 sensor breaker and give us an RCS onboard readout out of Eagle, but that's all. Columbia, Houston. We've got a state vector for you if you'll give us P00 in ACCEPT. Over.

Neil Armstrong (CDR)

Buzz says the CO2 sensor circuit breaker is IN

Charlie Duke (CAPCOM)

Roger. Thank you very much.

Neil Armstrong (CDR)

The RCS quantity was approximately 60 at A and 45 percent at B.

Neil Armstrong (CDR)

And we're going P00 in ACCEPT.

Charlie Duke (CAPCOM)

Columbia, Houston. Your friendly White Team's going to be on till we get you on the way home, and we'd like to congratulate everybody on a successful rendezvous and a beautiful EVA. It was a great show for everybody. Over.

Michael Collins (CMP)

Thank you, sir. I'll tell Neil and Buzz.

Neil Armstrong (CDR)

Houston, the hatch passes its integrity check. I'm going to go to LM tunnel VENT now, and leave it there.

Charlie Duke (CAPCOM)

Roger, Columbia. We copy. That's good, and we'd like a readout on the TEP of about the time you—that Eagle selected the secondary loop. Over.

Charlie Duke (CAPCOM)

Hello, Columbia. Houston. We got the load in. You can do the VERB 66 and the computer is yours. Over.

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.

Neil Armstrong (CDR)

There she goes. It was a good one.

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.

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.
