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

Elapsed time of 70 minutes.

John Young

Okay, at 70:18 give it to me.

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

Pulse control is real good.

Gus Grissom

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

Gus Grissom

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

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?

Gordon Cooper (CapCom)

Okay. Can you give us a helium source pressure?

Gordon Cooper (CapCom)

What is your helium source pressure?

John Young

Roger. It's 2350, Gordo.

Gus Grissom

Look at the sunrise.

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.

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.
