Charlie Duke (CAPCOM)

Apollo 11, Houston. Over.

Charlie Duke (CAPCOM)

Roger, 11. The problem on that initially—starting up the PTC was we failed to do the VERB 49 which—and load the desired initial attitude; so the DAP tried to take it back to the old attitude that we had started up in number of hours to go. That's why we picked up the rates in the other axes. We're going to wait in this attitude for about 20 minutes to dump out the rates again, and than we'll proceed with the VERB 49 and load our attitude that we have at the time—at this time. Over.

Michael Collins (CMP)

Okay. That sounds good, Charlie. When you get to the VERB 49, I'd like for you to give me the three gimbal angles that you want loaded.

Charlie Duke (CAPCOM)

And Apollo 11, Houston. We have your flyby PAD if you're ready to copy. Over.

Buzz Aldrin (LMP)

Houston, Apollo 11. Is that P30 PAD?

Charlie Duke (CAPCOM)

That's affirmative. Over.

Charlie Duke (CAPCOM)

All right, Buzz. It's—flyby is the purpose. SPS/G&N: 62815, plus 097, minus 020 070 54 5944, minus 00028, plus 00023, plus 00069 029 149 312, apogee is NA, plus 00221 00078 001 00034, sextant star 01 2385 227, boresight star is NA NA NA. Latitude is minus 0265, minus 16500, 11899 36228, 144 56 47. In the comments: your set stars are Deneb and Vega, 007 144 068. No ullage. It's a docked burn using the PTC REFSMMAT. Stand by for your readback. Over.

Buzz Aldrin (LMP)

Okay. Would you give me GET of O.05g again, please?

Buzz Aldrin (LMP)

Roger. Flyby SPS/G&N: 62815, plus 097, minus 020 070 54 5944, minus 00028, plus 00023, plus 00069, 269 149 312 NA, plus 00221 00078 001 00034, 01 2185 227 NA, minus 0265, minus 16500 11899 36228 144 56 47, Deneb and Vega, 007 144 068. No ullage; docked, PTC REFSMMAT. Over.

Charlie Duke (CAPCOM)

Roger. Say again your roll angle, Buzz. I copy—I read 029. Over.

Michael Collins (CMP)

Houston, Apollo 11. On the 0.7 rate, the rate loaded into the DAP is 0.1 or 0.2.

Charlie Duke (CAPCOM)

Hello, Apollo 11. Houston. Over.

Charlie Duke (CAPCOM)

Roger, Mike. Would you please copy down your VERB 16 NOUN 20 ICDU angles now, then execute a VERB 49 and load that—those angles, the NOUN 20 that you see on the DSKY into the VERB—into the NOUN 22 slot; and PRO on that, and that will start our 20-minute rate period. Over.

Michael Collins (CMP)

Okay, Charlie. I'll do that right now in just a matter of inches. Those numbers are plus 04511, plus 09021, and plus 35984. Over.

Michael Collins (CMP)

Houston, Apollo 11. I've done that and, of course, I got an immediate 50 18. So I guess we're set up to proceed from here, and I'll start the 20-minute timer.

Michael Collins (CMP)

Houston. I still question that 0.7 rate with 0.2 loaded into the DAP, though. Could you explain that one?

Charlie Duke (CAPCOM)

Roger. We're working on it.

Charlie Duke (CAPCOM)

Apollo 11, Houston. Over.

Charlie Duke (CAPCOM)

Roger. We got a little laser visual experiment we'd like to—for you to do for us. If—if you got the Earth through any of your windows or through the telescope, would you so advise? Over.

Michael Collins (CMP)

At this roll attitude, what should our highgain angles be? Maybe that would help us locate you. We don't see you in the lens.

Charlie Duke (CAPCOM)

Hello, Apollo 11. Houston. Those high gain angles are pitch minus 70, yaw 90. We think the Earth is apparently pretty close to plus z-axis. Over.

Michael Collins (CMP)

Okay, Charlie. I got you in the telescope.

Charlie Duke (CAPCOM)

Roger, Apollo 11. We've got a laser that we're going to—It's a blue-green laser that we're going to flash on and off at a frequency of on for a second, off for a second. It's coming out of McDonald Observatory near El Paso, which is—should be right on the terminator—or right inside the terminator. We are going to activate that momentarily. Would you please take a look through the telescope and see if you can see it. Over.

Michael Collins (CMP)

Okay, I'll try it with the telescope; and if I don't see it there, then I'll try the sextant.

Charlie Duke (CAPCOM)

Roger. We'll give you the word when they've got it turned on. Over.

Charlie Duke (CAPCOM)

11, Houston. They don't have it turned on yet. We'll give you the word when they got it turned on. Over.

Charlie Duke (CAPCOM)

Hello, Apollo 11. Houston. We noticed the CRYO pressure dropped a moment ago. Did you stir up the CRYO's? Over.

Neil Armstrong (CDR)

Roger. We've finished our cycling operations.

Charlie Duke (CAPCOM)

Hello, Apollo 11. Houston. McDonald's got the laser turned on, Would you take a look? Over.

Charlie Duke (CAPCOM)

It's bluish-green.

Charlie Duke (CAPCOM)

11, Houston. We got some shaft and trunnion for you that might tweak it up a little bit. Shaft of 141.5, trunnion of 39.5. Over.

Charlie Duke (CAPCOM)

Apollo 11, Houston. If you see it, it should be coming up—appear to be coming up, through the clouds. McDonald reports that there's a break in the clouds that they're beaming this thing through. Over.

Charlie Duke (CAPCOM)

Hello, Apollo 11. Houston. You can terminate the exercise on the Laser. Our rates are steady enough now for—to commence the PTC. Over.

Buzz Aldrin (LMP)

Okays Houston. Neither Neil nor Mike can see it. Incidentally, those shafts and trunnions just missed pointing at the world.

Buzz Aldrin (LMP)

As we are looking at it through the scanning telescope, it would be about a—oh, maybe a third of an Earth radii high and to the left.

Buzz Aldrin (LMP)

But, we did—but we did identify the El Paso area and it appeared to us to be a break in the clouds there, and we looked in that break and saw nothing.

Charlie Duke (CAPCOM)

Roger. Thank you much. Out.

Michael Collins (CMP)

Houston, Apollo 11. Over.

Michael Collins (CMP)

Were you following that on the DSKY?

Charlie Duke (CAPCOM)

11, Houston. What's your exact question? Over.

Michael Collins (CMP)

I've followed the procedure through step 7 down to the point where I've got 27303 ENTER, and this resulted in an OPERATOR ERROR LIGHT.

Charlie Duke (CAPCOM)

Apollo 11, Houston. Stand by a moment. We'll have an answer for you momentarily. Over.

Michael Collins (CMP)

Okay. Appreciate it, Charlie. Now the light's gone out without any further DSKY action.

Michael Collins (CMP)

Correction. Stand by; that's not so.

Charlie Duke (CAPCOM)

Roger. We've finally gotten concurrence on our problem here with 50 guys looking at it. When we were sitting in the 5018, we attempted to load the erasable before you terminated the VERB 49. So Mike, what we're going to have to do is call up the present CDU's, copy those down, and do a VERB 49, load the present, then do a PROCEED, then an ENTER, and then we can then set up ATTITUDE HOLD in step 6. Over.

Michael Collins (CMP)

Okay. I think that's what we did last time.

Charlie Duke (CAPCOM)

It appeared to us that we attempted to load the erasable prior to entering on the VERB 49 which VERB 49 was still running, and it clobbered the CDU's. Over.

Michael Collins (CMP)

Houston, Apollo 11. We're moving at the proper rate.

Charlie Duke (CAPCOM)

11, Houston. It looks great to us now. Over.

Michael Collins (CMP)

It looks fine here, Charlie. The 0.7 part is the only part I don't find explained yet.

Charlie Duke (CAPCOM)

Roger, Mike. We're working on that one right now. We're coming up with the story soon. Over.

Charlie Duke (CAPCOM)

11, Houston. We're handing over COMM to Goldstone. Over. Correction, from Goldstone to Honeysuckle. Over.

Michael Collins (CMP)

Hello, Houston through Honeysuckle. Ov —

Charlie Duke (CAPCOM)

Apollo 11, Houston. Go ahead. Over.

Michael Collins (CMP)

You sound good to us through Honeysuckle. How do we sound?

Charlie Duke (CAPCOM)

Roger. You're five-by, Mike. We'd like the OMNI configuration as follows. OMNI Alfa place in Bravo, OMNI to OMNI, high-gain track to MANUAL, high-gain yaw 270, pitch —

Charlie Duke (CAPCOM)

Hello, Apollo 11. Houston. How do you read now? Over.

Buzz Aldrin (LMP)

Roger. I'm reading you loud and clear. I'm not sure I got all those. I've got S-band OMNI B, OMNI, track to MANUAL, and beam wide, pitch—you'd better say that again, and yaw 270. Over.

Charlie Duke (CAPCOM)

Roger, Buzz. I broke up at pitch minus 50 at beam wide. Over.

Buzz Aldrin (LMP)

Houston, Apollo 11. Are you ready to copy some numbers on status report, et cetera.
