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?

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?

Roger. Stand by.
