Phase 5: Descent to the Moon

Charlie Duke (CAPCOM)

Hello, Eagle. Houston. We're standing by. Over.

Charlie Duke (CAPCOM)

Eagle, Houston. We see you on the steerable. Over.

Neil Armstrong (CDR)

Roger. Eagle is undocked.

Charlie Duke (CAPCOM)

Roger. How does it look, Neil?

Charlie Duke (CAPCOM)

Roger, Neil. We got a—If you will give us P00 and DATA, we've got the loads for you.

Buzz Aldrin (LMP)

Okay. You've got it. P00 and DATA.

Charlie Duke (CAPCOM)

Roger. Let us know when you are ready to copy. We have a DOI PAD, and a PDI PAD. Over.

Neil Armstrong (CDR)

You check our tracking light, Mike?

Neil Armstrong (CDR)

Back off? Okay. I'm ready to start my yaw maneuver if it suits you, Mike.

Neil Armstrong (CDR)

Does it look like you are going to be able to do this without burning thrusters, Mike?

Buzz Aldrin (LMP)

Go ahead, Houston. Eagle is ready to copy.

Charlie Duke (CAPCOM)

Roger, Eagle. Coming at you with a DOI PAD: 101 36 14.07. NOUN 81, minus 00758, plus all balls, plus 00098 plus—correction, 00572, perigee plus 00085 00764 030 000 293. NOUN 86, minus 00759, plus all balls, plus 00090. Rest of the PAD is NA. Stand by on your readback. If you are ready to copy the PDI data, I have it for you. Over.

Charlie Duke (CAPCOM)

Understand you are ready to copy the PDI data, Eagle. Over

Buzz Aldrin (LMP)

That's affirmative. Go ahead with the PDI.

Charlie Duke (CAPCOM)

Roger. PDI PAD: TIG 102 33 04.36 09 50, minus 00021, 182 287 000, plus 56919. PDI abort, less than 10 minutes, 105 12 30.00. PDI abort, greater than 10 minutes, 103 40 00.00 107 11 30.00.

NOUN 37 105 12 30.00. Ready for your readbacks, Over.

Charlie Duke (CAPCOM)

Eagle, Houston. We are through with the computer. You can go, back to BLOCK. Over.

Buzz Aldrin (LMP)

Roger. Back to BLOCK; and REALIGN: 101 36 14.07 minus 00758,plus all zeros, plus 00098 00572, plus 00085 00764 030 000 293, minus 000759, plus all zeros, plus 00090. NA. Over.

Charlie Duke (CAPCOM)

That was a good readback, Buzz. Go ahead. Over.

Buzz Aldrin (LMP)

Okay. PDI PAD: 102 33 04.36, 09 50, minus 00021 182 287 000, plus 56919. PDI less than 10: 105 12 30.00. PDI greater than 10: 103 40 00.00 107 11 30.00. No PDI plus 12 abort: 102 44 27.00, plus 01223, minus all zeros, plus 01889 01520, plus 00110 02250 046 000 190, plus 01187, plus 00000, plus 019011 103 31 07.00 105 12 30.00. Over.

Charlie Duke (CAPCOM)

Roger. Good readback, Buzz. Out.

Michael Collins (CMP)

Neil, I'm maneuvering in roll.

Buzz Aldrin (LMP)

Houston, Eagle. Are you copying the very large numbers for range and range rate in VERB 83? And did you just give us a state vector that changed one of the two vehicles? Over.

Charlie Duke (CAPCOM)

Roger, Eagle. We gave you a LM state vector. We have not changed the CSM state vector, however. Over.

Buzz Aldrin (LMP)

Okay. That explains it. Over.

Charlie Duke (CAPCOM)

Columbia, Houston. On my Mark 9 30 to ignition.

Charlie Duke (CAPCOM)

Eagle, Houston. Would you have Columbia go to the high gain, yaw 0, pitch minus 20. Over.

Neil Armstrong (CDR)

You want him to go to high gain yaw 0? Say again the numbers.

Charlie Duke (CAPCOM)

Roger, Neil. Yaw 0, pitch minus 20, high gain angles. Over.

Neil Armstrong (CDR)

Okay. Yaw 0, pitch minus 20 on the high gain.

Charlie Duke (CAPCOM)

That's affirmative. We've lost all data with him.

Neil Armstrong (CDR)

He says he'll do that as soon as he gets around there.

Charlie Duke (CAPCOM)

Columbia, Houston. How do you read?

Michael Collins (CMP)

I read you loud and clear, Houston. How me?

Charlie Duke (CAPCOM)

Roger, Mike. Five by. On my Mark 7 minutes to ignition.

Michael Collins (CMP)

I agree. Everything's looking real good.

Charlie Duke (CAPCOM)

Apollo 11, Houston. You are looking good for separation. You are GO for separation, Columbia. Over.

Michael Collins (CMP)

We're really stabilized, Neil. I haven't burned a thruster in 5 minutes.

Michael Collins (CMP)

I'll make a small trim maneuver.

Neil Armstrong (CDR)

Mike, what's going to be your pitch angle at SEP?

Neil Armstrong (CDR)

Okay.

Michael Collins (CMP)

Is that close enough for you or do you want it to a couple of decimal places?

Michael Collins (CMP)

I think you've got a fine looking flying machine there, Eagle, despite the fact you're upside down.

Michael Collins (CMP)

Okay, Eagle. One minute until TIG. You guys take care.

Michael Collins (CMP)

Houston, Columbia. My DSKY is reading 4.9, in X, 5.0 …, make it and EMS 105.4. Over.

Charlie Duke (CAPCOM)

Roger. Copy. Columbia, it looks good to us. Over.

Charlie Duke (CAPCOM)

Columbia, Houston. We'd like you to terminate average G. Over.

Neil Armstrong (CDR)

You're going right down U.S. 1, Mike.

Michael Collins (CMP)

Eagle, Columbia. At your convenience, I would like to switch over to VHF ranging modes.

Buzz Aldrin (LMP)

Roger. Let's go to VHF ranging now.

Michael Collins (CMP)

Eagle, Columbia. I am reading you loud and scratchy. Neil is not coming through too well on his VOX. Could you be quiet for 15 seconds while I get this locked on.

Michael Collins (CMP)

I've got a solid lock on. I have you at 0.27 miles.

Charlie Duke (CAPCOM)

Eagle, Houston. We've got a state vector for you. We'd like P00 and DATA. Over.

Charlie Duke (CAPCOM)

Columbia, Houston. We have a CSM rescue PAD if you are ready to copy. Over.

Charlie Duke (CAPCOM)

Roger, Mike. Phasing TIG 103 40 0000, TPI for PDI less that 10, 105 12 3000, TPI for PDI greater than 10, 107 11 3000. Over.

Michael Collins (CMP)

Roger. TIG's follow: phasing 103 40, PDI less than 10, 105 12 30 more than 10, 107 11 30. Over.

Charlie Duke (CAPCOM)

Eagle, Houston. When you are ready to copy, I have a lunar surface data PAD for you. Over.

Charlie Duke (CAPCOM)

We've got the load in, Eagle. You can go back updata link OFF. Over.

Charlie Duke (CAPCOM)

Columbia, Houston. At your convenience we'd like P00 and ACCEPT. We have a couple of state vectors for you. Over.

Michael Collins (CMP)

Okay. Going to P00 and ACCEPT, and I just got some unexplained roll thruster activity. I might have bumped the hand controller.

Charlie Duke (CAPCOM)

Roger. We will look at it. Out

Buzz Aldrin (LMP)

And Eagle is ready to copy lunar surface data PAD.

Charlie Duke (CAPCOM)

Roger, Buzz. Starting with the T2, T2 TIG: 102 54 2900 103 51 5600 106 37 3500 109 10 0000. In the remarks: T2 occurs at PDI plus 2126. T3 time—correction T3, T3 TIG: 104 39 4100 001 58 1500 001 58 5400. NOUN 11: 105 36 2300 107 11 3000. Ready for your readback. Over.

Buzz Aldrin (LMP)

Roger. T2: 102 54 2900 103 51 5600 106 37 3500 109 10 0000, T2 is PDI plus 2126. T3: 104 39 4100 001 58 1500 001 58 5400 105 36 2300 107 11 3000. Over.

Charlie Duke (CAPCOM)

Roger. Good readback, Eagle. Out.

Michael Collins (CMP)

Would you put your tracking light on, please?

Charlie Duke (CAPCOM)

Columbia, Houston. We've got the load in. You can go back to BLOCK. Over.

Charlie Duke (CAPCOM)

That's affirmative, Columbia.

Michael Collins (CMP)

Okay. Thank you, Houston.

Buzz Aldrin (LMP)

Mike, you want to give us a Mark when you're right at 7 miles—I mean seven tenths of a mile?
