RKV CapCom

Roger. Read you loud and clear. I'm going to update your TR and transmit a maneuver load to you.

RKV CapCom

I've got a reject on my TR. What is your status, Molly Brown?

John Young

Do you want me to tell them about the oxygen pressure being off-scale?

Gus Grissom

Our status is GO. We did bring the ECS O2 back down on the scale with O2 High Rate, and since that time it has returned to off-scale.

RKV CapCom

Roger, and I have transmitted a TR and Gemini load for your maneuver over Corpus. Confirm you were in CATCH-UP. Over.

Gus Grissom

Negative. We're in CATCH-UP, now.

RKV CapCom

Roger. I'll retransmit the load.

RKV CapCom

Roger. You have a load in the CATCH-UP for your maneuver.

Gus Grissom

Got to be in CATCH-UP.

John Young

Okay. There you go.

RKV CapCom

You are GO for the next orbit.

Gus Grissom

Roger. Thank you.

RKV CapCom

Are you ready to copy your maneuver times?

RKV CapCom

Roger.

Gus Grissom

You ready?

Gus Grissom

Okay. We're ready to copy.

RKV CapCom

Roger. Your GMTB…correction, 15 57 00. Your ground elapsed time to burn, 01 33 00. Your ΔV of the burn, 048. Your length of burn, 01:14.

John Young

Roger. We copied 15:57, 01:33, 48ft/sec, at a minute and 14 seconds.

Gus Grissom

Well, 1 minute 14. You want to read it back to them?

Gus Grissom

Did you get him the other one?

John Young

Neg. Wait until I'll get them.

RKV CapCom

Roger. Stand by for a GET time hack.

RKV CapCom

On my mark, it'll be 85 minutes and 45 seconds. Stand by.

RKV CapCom

MARK! You copied?

Gus Grissom

Roger. We copied.

RKV CapCom

Roger. Your clocks looked good on the ground.

RKV CapCom

Will you give me a readout of core 25, 26, and 27? Over.

John Young

26 and 27 are all zeros.

John Young

I wonder if he got it?

RKV CapCom

Molly Brown, RKV CAP COM.

John Young

Go ahead. Over.

RKV CapCom

Will you give me a readout of your computer core — 25, 26, and 27, please?

John Young

Roger. It was: 25 was minus 0480. 26 and 27 were all zeros. Over.

RKV CapCom

That is affirmative. I concur.

RKV CapCom

Molly Brown, can you give me a readout of your OAMS helium source pressure, temperature, and your propellant quantity gage.

Gus Grissom

The propellant quantity gage is 83 percent. Stand by. John will give you the other.

John Young

Roger. Source pressure is 2450. Source temperature is 85°, and fuel and oxidizer regulated at 295 with 68°.

RKV CapCom

Roger. 295 at 68. Say again your propellant quantity, Command Pilot.

Gus Grissom

Propellant quantity is 84 percent.

RKV CapCom

Molly Brown, RKV standing by. Do you have anything else?

Gus Grissom

Roger. We're in good shape.

RKV CapCom

Roger.

RKV CapCom

Molly Brown, RKV. I'm getting an indication of OAMS thrust forward-firing. I have negative OAMS yaw firing on the ground.

Gus Grissom

We're not doing any firing. We're not even in MANEUVER and ATTITUDE and we haven't touched the handle.

RKV CapCom

Roger.

RKV CapCom

Molly Brown, stand by for Guaymas.

John Young

Outstanding! I see the whole of Mexico.

John Young

I wonder what area of Mexico it is?

Guaymas CapCom

Molly Brown, Guaymas CAP COM.

Guaymas CapCom

Guaymas standing by.

Gus Grissom

It's pretty well clobbered, isn't it?

John Young

Yes.

Gus Grissom

We're going to have a hard time with that tracking task.

John Young

Can you see anything up north there?

Gus Grissom

I never got a chance to look for the Salton Sea, but I think we can see up that way.

Gus Grissom

Nothing but high cirrus.

John Young

Oh, man! Oh, man, you can see all the way across Mexico!

Gus Grissom

You must have it clear down there, huh?

John Young

Yes, it's clear down south, here.

Guaymas CapCom

Molly Brown, Guaymas handing over to Texas.

Gus Grissom

It came out 50 feet on my IVI's. You'll give me a mark now on my burn. Right?

Gus Grissom

Okay. It will be about two minutes before we start it. So you punch off your stopwatch and tell me — give me a mark to stop it—just in case it doesn't go to zero.

Gus Grissom

Read you loud and clear, Texas.

Roger Chaffee (CapCom)

Roger. Texas standing by for your maneuver.

Gus Grissom

You got that? The IVI's came out 50 ft/sec aft. Right?

John Young

Yes, but it should have been 48. I don't know why it came out to 50. Should we bring it down to 48?

John Young

Well 25—48 is what is in the—48.3 is what's in the load.

Gus Grissom

How we doing on time?

Gus Grissom

Well, good. I guess maybe we probably slowed down that much.

Gus Grissom

Now, it's 51. See?

Gus Grissom

It came up 48 initially. We're at a different place in the orbit. 30 seconds.

John Young

Okay. Are you going to give—you want me to give Texas a mark when you start burning?

Gus Grissom

Twenty seconds to burn. You got that, Texas?

Gus Grissom

Okay. 3 seconds.

Gus Grissom

Key moment First orbit change of a crewed spacecraft, lowering the orbit into an almost circular one: MARK!

John Young

Okay. They appear to be firing good.

Roger Chaffee (CapCom)

Roger. Texas confirms OAMS thruster firing.

Gus Grissom

A bolt just stuck up against the instrument panel.
