Gus Grissom

Yes, it's holding.

Gus Grissom

50—30—40. Those readings are right. You get 56?

John Young

Yes, 56 and 57 are right on the money. I copied them.

John Young

Okay, there it is — 10—20—30.

John Young

Okay, what time is it now?

Gus Grissom

70 minutes.

John Young

Huh?

Gus Grissom

Elapsed time of 70 minutes.

John Young

How many?

Gus Grissom

70.

John Young

Right now?

Gus Grissom

1:10. Yes.

John Young

Okay, at 70:18 give it to me.

Gus Grissom

MARK!

John Young

Okay, Blood Experiment deactivated.

Gus Grissom

Okay, that's exactly — that's 39° pitched down.

John Young

Okay, and you've got the sea urchin eggs coming up at 1:15, too.

Gus Grissom

Okay.

Gus Grissom

Pulse control is real good.

John Young

Yes.

Gus Grissom

It sure lights up all around though, doesn't it?

John Young

Sure does.

Gus Grissom

Okay, we're just about to get it all in one window.

John Young

Okay.

Gordon Cooper (CapCom)

Molly Brown, Cape CAP COM.

John Young

Okay, reading on the Catch-Up mode Check was 69 000 00.

Gus Grissom

Cape CAP COM, Molly Brown. Go ahead.

Gordon Cooper (CapCom)

Roger, Molly Brown, Cape CAP COM. We're going to have you leave your propellant switch on and do the Texas burn, and we will watch your fuel usage then across the States. If it continues, we'll have you turn your propellant switches off, then, when you're over the Cape next time, except when you need to use the fuel.

Gus Grissom

Leave the propellant switch on for the Texas burn, and then watch for leakage?

Gordon Cooper (CapCom)

Roger. Leave it on till after the Texas burn, and then we will watch your leakage. If it continues to leak, we will have you turn them off over the Cape.

Gus Grissom

Roger. We can't tell that we're using any fuel.

Gordon Cooper (CapCom)

Okay, fine. We are not overly concerned. It's just that we'd like to get a handle on what is causing it here.

Gordon Cooper (CapCom)

Your O2 pressure is off the scale on the high side by telemetry.

John Young

Say again, Gordo.

Gordon Cooper (CapCom)

Your oxygen pressure, your O2 pressure, is off the high side of the scale. You may have had that switch failure in there. you may have had a telemetry failure in there that failed to the high side.

John Young

Roger. We'll go to High Rate and see if it comes down, Gordo.

Gus Grissom

Roger, and Gordo we have lost our primary scanners.

Gordon Cooper (CapCom)

Roger. Did you say primary scanners?

Gus Grissom

Affirmative.

Gordon Cooper (CapCom)

Okay. Can you give us a helium source pressure?

Gus Grissom

Say again.

Gordon Cooper (CapCom)

What is your helium source pressure?

John Young

Roger. It's 2350, Gordo.

Gus Grissom

Look at the sunrise.

John Young

Yes.

John Young

Our source pressure is 2350, Gordo.

John Young

Let's see if I can bring that pressure down, using O2 High Rate, if it is all right with you, Gus.

Gus Grissom

Okay.

John Young

We can try manual actuation of O2 High Rate. I never did the Suit Integrity Check.

Gus Grissom

We probably drove it overboard using that heater switch when we thought the pressure was down.

John Young

Yes. That's right.

Gus Grissom

We have got to get ready for this Texas burn.

John Young

Yes.

Gus Grissom

What time is that Texas burn?

John Young

1:33.

Gus Grissom

1:33.

John Young

Now see, it is coming down.

Gus Grissom

Okay.

John Young

Now, we'll just recock it.

John Young

That was O2 High Rate for about two minutes to bring the pressure off the peg. it's now reading 985, and cabin pressure is holding at 5.6.

John Young

Here comes the sunrise. Is that beautiful!

Gus Grissom

Isn't that pretty?

Gus Grissom

Aren't you going to take any pictures?

John Young

I hadn't planned to on this pass. I'll get the camera out.

Gus Grissom

Let's see, I want circuit breakers 9 and 10 off, don't I?

John Young

Yes. That sun's bright, isn't it?

John Young

Look at that! Where do you suppose that came from?

Gus Grissom

What?

John Young

I know you shouldn't let those things float around, but I don't know what to do with them.

Gus Grissom

What did he say that burn was on that … net? It's 48 ft —

John Young

48 feet and 73 seconds.

Gus Grissom

Okay. you put that in, don't you?

John Young

Yes.

Gus Grissom

Do I have to be in CATCH-UP when you put it in?

John Young

What?

Gus Grissom

Do I have to be in CATCH-UP when you put it in?

John Young

For me to enter it, yes. I'll just put in on the MDIU indicators here.

Gus Grissom

Looks like the velocity is about perfect. You can really tell you're moving on. You know that?

John Young

You sure can!

John Young

I can see some interesting cloud formations down there.

Gus Grissom

We'll be coming up for Guaymas, I guess, next.

John Young

Okay, what elapsed time are we in the flight plan, Gus?

Gus Grissom

1:19

John Young

1:19

Gus Grissom

RKV we get at 1:24.

John Young

Okay.

Gus Grissom

I'd say my alinement is perfect.

John Young

Okay. That's what we want to burn. I've got to change this tape cartridge. The camera is set for f11 at 250.

John Young

The first command load is valid. The DCS at Carnarvon inserted it properly.

Gus Grissom

Okay.

John Young

That's beautiful!

John Young

I'll bet the debris filter really clogs up.

Gus Grissom

What?

John Young

The oxygen pressure has climbed right up back there off-scale.

Gus Grissom

What is?

John Young

The oxygen pressure.

John Young

I've got to change this cartridge.

Gus Grissom

We're at 1:21.

John Young

Tape change at 1546. Tape cartridge No. 2 was replaced by tape cartridge No. 28.

John Young

The red light did not come on.
