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.

Gus Grissom

Roger.

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.

Gus Grissom

Guaymas, Molly Brown.

Guaymas CapCom

Guaymas standing by.

Gus Grissom

Roger.

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

Roger.

Gus Grissom

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

John Young

Roger.

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.

John Young

Okay.

Roger Chaffee (CapCom)

Molly Brown, Texas CAP COM.

Gus Grissom

Read you loud and clear, Texas.

Roger Chaffee (CapCom)

Roger. Texas standing by for your maneuver.

Gus Grissom

Roger.

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?

John Young

Fine.

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

I will.

John Young

Okay.

Gus Grissom

Twenty seconds to burn. You got that, Texas?

Roger Chaffee (CapCom)

Roger.

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.

Gus Grissom

How much time to go?

Roger Chaffee (CapCom)

Molly Brown, how are your attitudes holding?

Gus Grissom

Perfect.

John Young

44 seconds to go.

Roger Chaffee (CapCom)

Roger.

John Young

MARK. 44 seconds to go.

John Young

I think I'd do it on the IVI's.

Gus Grissom

They sure blurp a lot, don't they? That may be attitude control thrusters though. Probably what it is.

John Young

Okay.

John Young

Coming up on—coming up on a minute.

John Young

MARK.

Gus Grissom

7 ft/sec to go.

John Young

A minute, five.

Gus Grissom

What did we do? Burn down an—give me a mark.

John Young

Okay. 4—3—2—1 -

John Young

MARK!

Gus Grissom

Thrusting complete.

Roger Chaffee (CapCom)

Roger. Confirmed maneuver complete.

John Young

That burn was 1 minute and 14 seconds by our watches.

Gus Grissom

And when we started out, the IVI's were reading 51 ft/sec, and I burned them down to 2 ft/sec aft.

Roger Chaffee (CapCom)

Say again, Molly Brown.

Gus Grissom

As we started to burn my IVI's read 51 ft/sec, and we burned them down to the place where they read 2 ft/sec.

Roger Chaffee (CapCom)

Say again that last number.

Gus Grissom

Two. Zero, zero, two.

Roger Chaffee (CapCom)

Roger.

John Young

What have you got on your propellant, Gus?

Gus Grissom

Propellant quantity is 65 percent.

John Young

Hey, we're in good shape.

Gus Grissom

Yes.

Gordon Cooper (CapCom)

Molly Brown, Cape CAP COM.

Gus Grissom

Go ahead, Gordo.

Gordon Cooper (CapCom)

Roger. Do you want to get your transmitter up to start your tape dump?

Spoken on March 23, 1965, 3:54 p.m. UTC (59 years, 7 months ago). Link to this transcript range is: Tweet

John Young

Yes, it's on. The transmitter is now DELAYED-TIME.

Gordon Cooper (CapCom)

Ready for your tape dump?

John Young

Understand. Going tape playback CONTINUOUS.

John Young

Tape playback is on CONTINUOUS.

Gordon Cooper (CapCom)

Okay, Molly Brown. Looks like your OAMS has leveled out before your burn. Can you give us an OAMS source pressure and temp again now?

John Young

Roger. Source pressure is 2050, temperature is 56.

Gordon Cooper (CapCom)

Molly Brown, Cape CAP COM.

John Young

Oh, that record switch!

John Young

This source pressure is 2050. Source temperature is 56.

Gordon Cooper (CapCom)

Roger. it looks like that pressure switch on that O2 is failed. You probably better bring that O2 heater from AUTOMATIC to OFF, and then manually control the temp from then on—the pressure from then on.

John Young

If I go into High Rate you can break it off the peg. Over.

Gordon Cooper (CapCom)

Okay, you can bring it off the peg by going to High Rate. Is that affirm?

John Young

Roger, but—

Gordon Cooper (CapCom)

Okay. I have a time for you, where you will be nearest to the booster. Would you like to have that so you can look for it?

John Young

Roger.

Gordon Cooper (CapCom)

Roger. 02 + 08 + 52. Will be dead ahead at an elevation of plus 80° at 190 miles. This will be just prior to darkness. It should be very bright. Proceed to see if you can rendezvous.

Gus Grissom

Roger.

Gordon Cooper (CapCom)

We are sending you a load now.
