Buzz Aldrin (LMP)

That's it. Got a good lockon, Houston.

Buzz Aldrin (LMP)

Your really think its apogee is 125 21, huh? 25 … That circuit breaker is in.

Buzz Aldrin (LMP)

Engine arm circuit breaker.

Buzz Aldrin (LMP)

Okay. There's a mark. Buy that?

Ronald Evans (CAPCOM)

Eagle, Houston. If you have time, pitch 162, yaw minus 16.

Buzz Aldrin (LMP)

You load the REFSMMAT? Okay.

Michael Collins (CMP)

Eagle, Columbia. Your Y dot is minus 1.0. Over.

Michael Collins (CMP)

Eagle, do you read Columbia? Over.

Michael Collins (CMP)

Eagle, this is Columbia. Over.

Michael Collins (CMP)

Houston, Columbia. Over.

Ronald Evans (CAPCOM)

Roger, Columbia. Loud and clear now. This is Houston.

Michael Collins (CMP)

Roger. Would you tell Eagle his Y dot is minus 1.0. Over.

Ronald Evans (CAPCOM)

Roger. Eagle, Columbia says your Y dot is minus 1.0. Over.

Neil Armstrong (CDR)

Roger, Houston. We got that. Thank you.

Ronald Evans (CAPCOM)

Roger. And you can go high bit rate now. Eagle can.

Michael Collins (CMP)

Eagle, Columbia. How do you read?

Buzz Aldrin (LMP)

AGS agrees very closely, and pointing …

Michael Collins (CMP)

Houston, Columbia is unable to read Eagle on either antenna or on VHF duplex Bravo. You got any suggestions?

Ronald Evans (CAPCOM)

Roger. Columbia, we understand. You are unable to read Eagle. Stand by.

Neil Armstrong (CDR)

Houston, tell Columbia that we read him about strength 2.

Buzz Aldrin (LMP)

Okay. Wide deadband on.

Michael Collins (CMP)

Houston, Columbia. Also my VHF ranging is not working now, and I'd like to know whether you'd like me to continue making sextant marks or do nothing. I'm supposed to be doing VHF marks only, and it's for the next 6 or 7 minutes.

Ronald Evans (CAPCOM)

Columbia, Houston. Roger. We copy. And, Eagle, looks like the best antenna would be forward for the LM. And, break. Eagle, we missed your loading of the TPI TIG and P32. Could you confirm you've done that?

Ronald Evans (CAPCOM)

Columbia, Houston. Recommend you take sextant marks and do not reinitialize. Over.

Michael Collins (CMP)

Roger, Houston. Columbia's got the VHF ranging back now. I'll stick with the nominal. Thank you.

Michael Collins (CMP)

Columbia reading you loud and clear now, Eagle.

Ronald Evans (CAPCOM)

Roger. Mike, you can go ahead and get as many VHF and sextant marks as you can here in this period of time.

Michael Collins (CMP)

Roger. I've just got time for maybe two sextant marks, then get on with the final count.

Ronald Evans (CAPCOM)

Eagle and Columbia, about 1 minute till LOS there on Columbia. It looks like we have about 51.5 for CSI, and we tend to confirm your Y dot. And, break. For Eagle, verify VHF Bravo transmitter is off.

Buzz Aldrin (LMP)

Roger. VHF Bravo is off.

Ronald Evans (CAPCOM)

Eagle, Houston. Recommend aft OMNI and are you GO for CSI, so we can let Columbia know. Over.

Buzz Aldrin (LMP)

Roger. We're GO for CSI.

Ronald Evans (CAPCOM)

Columbia, Houston. Did you copy? Eagle is GO for CSI.

Michael Collins (CMP)

No, I did not copy. I'm reading them only intermittently, but thank you.

Ronald Evans (CAPCOM)

Eagle, Houston. We'll see you coming around the other side. Your AOS time—is 1 minute ahead of the flight plan.

Ronald Evans (CAPCOM)

Columbia, Houston. Heard you talked to Eagle? I assume you have COMM with Eagle now?

Michael Collins (CMP)

Houston, Columbia in OMNI D Delta. Over.

Michael Collins (CMP)

Houston, Columbia. Over.

Ronald Evans (CAPCOM)

Columbia, Houston. You're very weak. Say again.

Michael Collins (CMP)

Roger. Houston, Columbia. CSI nominal; no plane change. Everything's going beautifully, and the LM seems to be …your laser…

Ronald Evans (CAPCOM)

Columbia, Houston. You're about one by, I could just barely make you out. I can't understand.

Michael Collins (CMP)

Houston, Columbia. How now?

Michael Collins (CMP)

Houston, Columbia. Over.

Michael Collins (CMP)

Houston, Columbia. Over.

Michael Collins (CMP)

Houston, Columbia. Over.

Buzz Aldrin (LMP)

Houston, this is Eagle. Over.

Ronald Evans (CAPCOM)

Hey, Eagle. Houston loud and clear. Columbia was very weak. We were unable to read him.

Buzz Aldrin (LMP)

Roger. We saw you come up over the horizon and it looks like you had a laser operating. Could you confirm that?

Ronald Evans (CAPCOM)

Eagle, Houston. Stand by. We'll check it. And, Eagle, Houston. Can you give us a burn report?

Buzz Aldrin (LMP)

Okay. The CSI burn was on scheduled time of 125 19 3470, 51.5 feet per second was our solution. After chasing residuals a little bit, we ended up with a minus 0.2, plus 0.7, and minus 0.1. And in the AGS, at that time, we had plus 0.4, plus 0.9, and plus 0.3.

Ronald Evans (CAPCOM)

Eagle—Eagle, Houston. We copy. Any plane change? Over.

Buzz Aldrin (LMP)

No. There was no plane change on CSI, and CSM had a 2.3 foot per second burn. We had a 2.9, and we elected to postpone that. Over.

Ronald Evans (CAPCOM)

Roger. We copy, Eagle. Thank you.

Michael Collins (CMP)

Houston, how do you read Columbia now?

Michael Collins (CMP)

Eagle, how about asking them for some high gain angles for me, will you, please?

Buzz Aldrin (LMP)

Roger, Houston, do you have some high gain angles for Columbia? Over.

Ronald Evans (CAPCOM)

Roger, Eagle. And, Columbia, stand by. We'll have them for you shortly.

Ronald Evans (CAPCOM)

Eagle, Houston. Could you verify you switched lithium hydroxide canisters? Over.

Buzz Aldrin (LMP)

That's affirmative. We started getting an erratic indication on primary, so we switched to secondary, and it was again erratic and I thought it might have been a sensor. But it's settled down now, and we're on the secondary. Over.

Ronald Evans (CAPCOM)

Roger. We copy. Mighty fine.

Ronald Evans (CAPCOM)

Columbia and Eagle. Request OMNI Delta for Columbia.

Michael Collins (CMP)

Roger, Houston. I've been in Delta the whole time but it doesn't …

Neil Armstrong (CDR)

Houston. Columbia's been on Delta, but he hasn't had much luck with you.

Ronald Evans (CAPCOM)

Eagle, Houston. Roger. We copy.

Michael Collins (CMP)

Eagle, are you ready to copy your Y dot?

Michael Collins (CMP)

Ronald Evans (CAPCOM)

Eagle, Houston. At your convenience, we'd like to go ahead and try your lithium hydroxides on the primary and let us take a look at it down here.

Ronald Evans (CAPCOM)

Columbia, Houston. Over.

Neil Armstrong (CDR)

Houston, Eagle. Columbia's been reading you loud and clear on his OMNI's, but he hasn't had any luck in transmitting to you.

Ronald Evans (CAPCOM)

Roger, Eagle. Mighty fine. We don't hear Columbia though.

Buzz Aldrin (LMP)

We're burning ours, Mike. Minus 1.8.

Ronald Evans (CAPCOM)

Columbia, Houston. Over.

Ronald Evans (CAPCOM)

Columbia, Houston. You can go ahead and go to REACQ in the high gain. We should get you then.

Buzz Aldrin (LMP)

Do you have some angles for him, Houston?

Ronald Evans (CAPCOM)

Roger. Pitch minus 30, yaw 180, for Columbia.

Buzz Aldrin (LMP)

Okay. And what was your CSICDH solution, Mike?

Buzz Aldrin (LMP)

Roger. Copy. Thank you.

Neil Armstrong (CDR)

And, Houston, Eagle. Got an ECS light—a CO2 light. Partial pressure's reading about one half millimeter.

Ronald Evans (CAPCOM)

Eagle and Columbia, Houston. Roger. We copy.

Michael Collins (CMP)

Houston, how do you read Columbia?

Ronald Evans (CAPCOM)

Eagle, Houston. We're sure that's a sensor problem. You can leave it on PRIMARY.
