Spacelog Apollo 11

Apollo 11, this is Houston. Over.

Go ahead, Houston.

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

Go ahead. Ready to copy.

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.

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

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?

Stand by.

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.

Houston, Apollo 11. Over.

Go ahead, 11. Over.

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

Houston, Apollo 11. Over.

Roger, 11. Do you read me? Over.

Hello, Apollo 11. Houston. Over.

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.

That sounds fine to us. Over.

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

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

Roger.

I read it 158 right now, Charlie.

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

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

Houston, Apollo 11. Do you read?

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

11, how do you read me? Over.

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?

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.

Okay, fine.

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

Roger. Copy.

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.

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

Roger. Copy.

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

11, Houston. Say again. Over.

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.

Roger. Copy. Thank you.

Makes you almost glad to get master alarms.

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

Roger, 11. We copy that here. Over.

Okay.

Boy, that transducer's working somewhat.

Roger.

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.

Stand by, Charlie.

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?

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.

Roger.

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.

Roger.

Our flow is stabilized now at 0.6.

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

Okay.

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

Roger.

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

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

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.

Roger.

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.

Ready to copy.

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.

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.

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.

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

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

Yes, it's loose now.

Can you see that?

Roger, Neil. It's really good.

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

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.

I think those are the tunnel lights.

…

Oh, Okay. You're right.

Okay. It's loose now. Coming down.

Roger.

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

You bet. This is the only way …

You have to take it easy.

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

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.

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

Roger.

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

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.

Roger.

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

Roger.

Okay. Drogue removal's coming next.

Roger. As we suspected.

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

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