Phase 8: Towards Earth

Charlie Duke (CAPCOM)

Hello Apollo 11. Houston. How did it go? Over.

Michael Collins (CMP)

Time to open up the LRL doors, Charlie.

Charlie Duke (CAPCOM)

Roger. We got you coming home. It's well stocked.

Neil Armstrong (CDR)

Okay, Burn status: DELTA-TIG was zero, burn time was 2 plus 30. PAD angles: DELTA VGX after trim was 0.1, VGY 0.9, VGZ 0.1. DELTA-VC minus 17.9, fuel 10.6, OX 10.4, unbalance minus 50.

Charlie Duke (CAPCOM)

Roger. Copy, Neil. Sounds good to us.

Charlie Duke (CAPCOM)

And Apollo 11, Houston. All your systems look real good to us. We'll keep you posted.

Neil Armstrong (CDR)

Hey, Charlie boy, looking good here. That was a beautiful burn. They don't come any finer.

Charlie Duke (CAPCOM)

Apollo 11, Houston. I wondered if you've compared your state vector accuracy with the one in the LM flights? Over.

Neil Armstrong (CDR)

Yes, sir, and it looked very nice. VERB 83 was plus 00070 and minus 00008.

Charlie Duke (CAPCOM)

11, Houston. I was looking at your bank Bravo nitrogen tank. It didn't leak a bit—correction—didn't leak a bit this time. Over.

Neil Armstrong (CDR)

Roger. Looked good here.

Michael Collins (CMP)

Chamber pressure was hanging in there around 100. The latter part, of the burn it started oscillating a little bit and got down a little bit below 100.

Charlie Duke (CAPCOM)

Apollo 11, Houston. Would you give us P00 in ACCEPT? We've got a REFSMMAT for you. Over.

Charlie Duke (CAPCOM)

Hello, Apollo 11. Houston. We've got the load in. You can go back to BLOCK. Over.

Michael Collins (CMP)

Your command module film seems to be working out pretty well, Charlie, the amount we carried. Looks like we carried just about what we needed.

Michael Collins (CMP)

We have one 16 millimeter roll on the ASA 1000 color interior film. We were thinking of shooting that during the entry, out window number 4 on a bracket, and you might get the camera guide sometime in the next couple of days and give us all the good settings for that.

Charlie Duke (CAPCOM)

Hello, Apollo 11. Houston. I wondered if during the TEI burn you utilized the oxidizer flow valve on the PUGS. Over.

Buzz Aldrin (LMP)

Yes, we did. Based on your very excellent briefing I was expecting the thing to continue desiring increase for the whole time, so we started out with it in INCREASE. I saw that we pretty quickly crossed the line and started falling about 6 or 7 percent behind, so I was still expecting it to move up, and then I went down to FULL DECREASE and brought it back down to a difference of 2 percent. Over.

Charlie Duke (CAPCOM)

Roger. Thank you very much, Buzz.

Buzz Aldrin (LMP)

Two tenths of a percent, I'm sorry.

Charlie Duke (CAPCOM)

Apollo 11, Houston. You can go to PTC attitude and torque at your—and do the P52 and torque at your convenience. Over.

Michael Collins (CMP)

Hey, we got to take some more pictures, Charlie. Is there any constraint, normally, in staying here for awhile?

Michael Collins (CMP)

How does that tracking look, or is it too early to tell?

Charlie Duke (CAPCOM)

Apollo 11, Houston. FIDO's are looking at the data. It's too early to tell yet exactly. It's looking real good so far. We'll have you some answers shortly on trajectory. Over.

Michael Collins (CMP)

Okay. What FIDO is that?

Charlie Duke (CAPCOM)

11, Houston. We have a DAP CSM update for you.

Charlie Duke (CAPCOM)

Roger. CSM weight, Mike: 26370. Over.

Charlie Duke (CAPCOM)

Apollo 11, Houston. We've taken your onboard vector and propagated it forward, and it's looking real good. We only got about 24 minutes of tracking now. Really too early to tell on the radar. Over.

Charlie Duke (CAPCOM)

Hello, Apollo 11. Houston. Mike, did you notice any transients at ignition on TEI? Over.

Michael Collins (CMP)

Yes. The transients were more noticeable than on the previous burns, Charlie. I just wrote it off on the fact we had a light command module, but there was considerable roll activity which dampened down after the first 20 seconds, I would guess, of the burn; but then there was also some pitch and yaw activity. I don't believe it was abnormal, and it seemed to be deadbanding ratherly crisply in roll plus or minus about 8 degrees either side of the center line; and after the first couple of—oh, after the first 20 seconds or so, the gimbals were quiet, and pitch and yaw were relatively quiet. Before that, there was some oscillation but mostly just in rates. Total attitude hung in there pretty well.

Charlie Duke (CAPCOM)

Roger. Thank you much. We were looking at the playback, and we saw some things that—right at start up. We'll be back with you later on that.

Charlie Duke (CAPCOM)

Apollo 11, Houston. Have you finished taking pictures? Over.

Michael Collins (CMP)

We're just finishing up, Charlie.

Michael Collins (CMP)

About to get started on the P52 here pretty soon.

Michael Collins (CMP)

Another eight or nine of them.

Charlie Duke (CAPCOM)

Hello, Apollo 11. Houston. You can crank up on the PTC at any time. Over.

Deke Slayton

Apollo 11, Houston.

Deke Slayton

Roger, 11. This is the original CAP COM. Congratulations on an outstanding job. You guys have really put on a great show up there. I think it's about time you powered down and got a little rest, however. You've had a mighty long day here. Hope you're all going to get a good sleep on the way back. I look forward to seeing you when you get back here. Don't fraternize with any of those bugs enroute except for the Hornet.

Neil Armstrong (CDR)

Okay. Thank you, boss. We'll—We're looking forward to a little rest and a restful trip back. And see you when we get there.

Deke Slayton

Roger. You've earned it.

Charlie Duke (CAPCOM)

Hello, Apollo 11. Houston. We'd like you to turn off O2 tank number 1 heaters. Over.

Charlie Duke (CAPCOM)

Hello, Apollo 11. Houston. For your information, the LGC in Eagle just went belly up at 7 hours. Over.

Neil Armstrong (CDR)

Okay. Very good, … death of a real winner, there.

Michael Collins (CMP)

Charlie, we're going to rotate about pitch 270 degrees on the way home vice 1—or 090 on the way out. Right?

Michael Collins (CMP)

Okay. VERB 49 maneuver to that attitude is in progress.

Neil Armstrong (CDR)

Houston, crew status report. Radiation: CDR 11017, CMP 10019, LMP 09020. No medication.

Charlie Duke (CAPCOM)

Say again, please, Neil. We—you were breaking up. We missed that. Over.

Neil Armstrong (CDR)

Okay. This is crew status report. Radiation: CDR 11017, CMP 10019, LMP 09020. No medication.

Charlie Duke (CAPCOM)

And we didn't get any crew status report from you this morning. Wondered if you could give us an estimate of sleep last night. Over.

Neil Armstrong (CDR)

Okay. We'll take a guess, Charlie, and try to give an equivalent amount. Oh, it's CDR 3, and LMP 4.

Charlie Duke (CAPCOM)

Roger. Thank you very much.

Neil Armstrong (CDR)

And, Charlie, you want the fans cycled … Right?

Charlie Duke (CAPCOM)

That's affirmative, and we'd like you to disable quads Charlie and Delta. Over.

Michael Collins (CMP)

Okay. Charlie and Delta.

Charlie Duke (CAPCOM)

Apollo 11, Houston. If it's convenient, we'd like to go through your onboard readout. Over.

Charlie Duke (CAPCOM)

Oh, excuse me. It's on the flight plan, 3102. We'd like BATTS and RCS. Over.

Michael Collins (CMP)

BATT Charlie 370, PYRO BATT A 370, BATT B 370; RCS, 55, 65, 64, and 62. Over.

Charlie Duke (CAPCOM)

Roger. We copy all that. Thank you much.

Charlie Duke (CAPCOM)

Apollo 11, Houston. A couple of questions for the Moon walkers, if you got a second. Over.

Charlie Duke (CAPCOM)

Roger, Neil. We're seeing some temperature rises on the passive seismic experiment that are a little higher than normal and were wondering if you could verify the deployed position. We understand it's about 40 feet from the LM in the eleven o'clock position. Over.
