CapCom

Apollo 11, this is Houston. Over.

CapCom

Roger. We have a TV attitude for you if you're ready to copy.

Michael Collins (CMP)

Go ahead. Ready to copy.

CapCom

Okay. We recommend stopping PTC at GET of 54 45 00, and this should put you at just about the right roll angle. The attitude we recommend is roll 263, pitch 090, yaw 000. This gives you the Earth out of window number 1 in the command module and places the high gain antenna in the CSM window for TV at your convenience. You will also have the Sun shining in—or shining at the hatch on the LM, and if you take down the window shades you should get some sunlight in. We're recommending wide deadband. Over.

Michael Collins (CMP)

Roger. Thank you, Houston. We'll look at that.

Michael Collins (CMP)

Houston, Apollo 11. When we pass the proper roll angle, we're not going to be anywhere near zero degrees yaw. Do you want us to just stop and try until we find ourselves in and then VERB 49 the three angles you gave us?

CapCom

Hello, Apollo 11. Houston. We'd like you to stop at the proper roll angle, then do a VERB 49 to the roll and pitch. Over. Correction, roll and yaw.

Michael Collins (CMP)

Houston, Apollo 11. Over.

CapCom

Go ahead, 11. Over.

CapCom

Hello, Apollo 11. Houston. Do you read? Over.

Michael Collins (CMP)

Houston, Apollo 11. Over.

CapCom

Roger, 11. Do you read me? Over.

CapCom

Hello, Apollo 11. Houston. Over.

Michael Collins (CMP)

Stand by, Charlie. Yes, we're going to come out of PTC here at 263 roll and then do VERB 49 to the recommended attitude.

CapCom

That sounds fine to us. Over.

Charlie Duke (CAPCOM)

Hello, Apollo 11. Houston. Before you open the pressure equalization valve, we'd like the LM/CM DELTA-P. Over.

Michael Collins (CMP)

Okay. Let me check it again. It was about 155.

Michael Collins (CMP)

I read it 158 right now, Charlie.

Michael Collins (CMP)

Houston, Apollo 11. We're stopping PTC at 263 … 0.

Charlie Duke (CAPCOM)

11, Houston. You're about one-by on this transmission. Say again. Over.

Michael Collins (CMP)

Houston, Apollo 11. Do you read?

Michael Collins (CMP)

Houston, Apollo 11. How do you read on the high gain?

Charlie Duke (CAPCOM)

11, how do you read me? Over.

Michael Collins (CMP)

Read you loud and clear, Charlie. We just switched to HIGH GAIN, and we stopped PTC at roll 263, pitch 90, yaw 0. How do you read?

Charlie Duke (CAPCOM)

Roger, Mike. You're five-by now on the high gain. We're right between the OMNI antennas and pretty horrible COMM on the OMNI's. We got you five-by on the high gain, and we copy the PTC stoppage. Over.

Michael Collins (CMP)

Houston, we're going to open the DIRECT O2 valve and start pumping up the cabin.

Charlie Duke (CAPCOM)

Apollo 11, Houston. We're going to hand over to Goldstone for uplink in about 2 minutes. We might have a momentary dropout of COMM. Over.

Michael Collins (CMP)

Alright. Can you hear our master alarm in the background? That's O2 FLOW HIGH coming through this amplifier.

Michael Collins (CMP)

That photoelectric cell is a good device. It's worked very well.

Charlie Duke (CAPCOM)

11, Houston. Say again. Over.

Michael Collins (CMP)

I say that photoelectric cell amplifier for the master alarm is a good device. It's working very well, and it's a nice pleasing tone.

Michael Collins (CMP)

Makes you almost glad to get master alarms.

Michael Collins (CMP)

Houston, Apollo 11. As a matter of curiosity, our O2 flow meter is pegged FULL-SCALE HIGH.

Charlie Duke (CAPCOM)

Roger, 11. We copy that here. Over.

Michael Collins (CMP)

Boy, that transducer's working somewhat.

Charlie Duke (CAPCOM)

11, Houston. We'd like to try to attempt to correlate your O2 flow in transducer with the flow valve that you've got open. How far—How far open would you say you have the REPRESS O2? Over. Correction, the DIRECT O2.

Michael Collins (CMP)

Okay, Charlie. It's not open very far. It's hard to give you a good reading without shunting it again, but the arrow is at about the one o'clock position. Now I reduce the flow, and I'll let it stabilize here. Right now our onboard reading is about 0.4, and that's with the arrow in the O2 valve at the two o'clock position. Would you rather have comparisons of O2 flow readings or would you rather have valve position comparisons?

Charlie Duke (CAPCOM)

EECOMM's say they'd like to look at valve positions. Over.

Michael Collins (CMP)

Okay. Well, we're holding steady now at 0.3 pound per hour, and our cabin pressure is about 54; and I'll close the valve momentarily and then open it again to this position and tell you how much travel is required.

Michael Collins (CMP)

It's about 30 degrees of travel, Charlie, from the closed position, which is with the arrow pointing at about three to three-thirty, four o'clock.

Michael Collins (CMP)

Our flow is stabilized now at 0.6.

Charlie Duke (CAPCOM)

Roger. We copy. We're reading the same.

Michael Collins (CMP)

Yes, open it back to the one o'clock position.

Michael Collins (CMP)

Is that enough different positions, or you want more, Charlie?

Charlie Duke (CAPCOM)

Mike, that's good—good enough. We're satisfied now. Over.

Michael Collins (CMP)

Houston, Apollo 11. We've terminated direct O2, our cabin pressure is 57, and, as a matter of curiosity, when we turn the DIRECT O2 valve OFF, we get a master alarm just like they did in the spacecraft testing.

Charlie Duke (CAPCOM)

11, Houston, we have a little update for you. When you go into the LM, we'd like you to unstow and bring back to the command module the following items. Over.

Charlie Duke (CAPCOM)

Roger. We'd like you to pick up the—out of the flight data file, the surface checklist, the mission rules NO-GO card, the DPS, APS, RCS limit cue card. Over.

Charlie Duke (CAPCOM)

Apollo 11, Houston. The reason we wanted you to bring those three items back, we'll have some updates for you, for those three. Over.

Michael Collins (CMP)

Roger. We figured you would.

Charlie Duke (CAPCOM)

Apollo 11, Houston. We're getting the TV at Goldstone. We're not quite configured here at Houston for the transmission. We'll be up in a couple of minutes. Over.

Michael Collins (CMP)

Roger. This is just for free. This isn't what we had in mind.

Charlie Duke (CAPCOM)

Apollo 11, Houston. It's a pretty good show here. It looks like you almost got the probe out.

Charlie Duke (CAPCOM)

Roger, Neil. It's really good.

Neil Armstrong (CDR)

Not much light up in that area, but apparently the TV set's able to pick it up.

Charlie Duke (CAPCOM)

There are some bright spots shining on the probe. Apparently Sun shafting on it that just gets just about enough for us to make it out. Over.

Neil Armstrong (CDR)

I think those are the tunnel lights.

Unidentified crew member

Neil Armstrong (CDR)

Okay. It's loose now. Coming down.

Charlie Duke (CAPCOM)

Looks like it's a little bit easier than doing that in the chamber.

Neil Armstrong (CDR)

You bet. This is the only way …

Michael Collins (CMP)

You have to take it easy.

Neil Armstrong (CDR)

It's pretty massive, but it goes where you direct it.

Charlie Duke (CAPCOM)

11, Houston. That's a beautiful picture now, we've got. We're looking at a 12-second delay. To us you are just bringing it down by the optics now.

Neil Armstrong (CDR)

Mike must have done a smooth job in that docking. There isn't a dent or a mark on the probe.

Charlie Duke (CAPCOM)

We're really getting a great picture here, 11. Over.

Charlie Duke (CAPCOM)

11, Houston. With a 12-foot cable, we estimate you should have about 5 to 6 feet excess when you get the camera into the LM. Over.

Charlie Duke (CAPCOM)

We can see the probe now. Correction, the drogue.

Neil Armstrong (CDR)

Okay. Drogue removal's coming next.

Charlie Duke (CAPCOM)

11, Houston. Now it's a good view of the storage area under the couch.

Charlie Duke (CAPCOM)

11, Houston. Looks like you're pretty crowded in there with that drogue. Over.
