Gus Grissom

I'm going to use them all.

Gus Grissom

Roger. 5 seconds . . .

John Young

Using the aft ones?

Gus Grissom

No, forward-firing ones.

Gus Grissom

9 ft/sec-10. Okay, now 1 second on the others.

CSQ CapCom

Molly Brown, CSQ. Would you give us your IVI readouts before and after the burn?

Gus Grissom

Roger, IVI readouts before the burn were all zeros. After the burn was 10 ft/sec forward.

CSQ CapCom

Roger. Understand. 10 ft/sec forward.

Gus Grissom

That was in the 009° attitude. 10 ft/sec forward.

CSQ CapCom

Roger.

Gus Grissom

That was with a 90° yaw.

CSQ CapCom

Molly Brown, CSQ. Be advised I sent TX twice. I've had spacecraft reject. I'll try again.

CSQ CapCom

Molly Brown, CSQ.

CSQ CapCom

We still cannot get an … back from spacecraft on TX.

John Young

Roger, I'll set the TX for the … Over.

CSQ CapCom

Say again.

CSQ CapCom

Molly Brown, CSQ. How did your attitudes hold during the maneuver?

John Young

Attitudes held very well.

CSQ CapCom

Roger.

CSQ CapCom

Molly Brown, CSQ.

CSQ CapCom

You still look real good from the ground here.

John Young

Okay. Replaced the tape recorder cartridge.

CSQ CapCom

Molly Brown, CSQ CAP COM.

CSQ CapCom

Would you give us a propellant quantity readout before and after the burn?

Gus Grissom

Before the burn it was 66 percent, and now it reads 61 percent.

CSQ CapCom

Molly Brown, say again.

Gus Grissom

66 percent before, 61 percent after.

CSQ CapCom

Roger.

Gus Grissom

I'm not real sure of that before burn.

John Young

At 1645 GMT, changed the tape from No. 28 to No. 10. Okay.

CSQ CapCom

That looks like it's in the ball park.

Gus Grissom

This thing isn't alined, is it?

John Young

I think you're right.

Gus Grissom

Give it one more chance.

Gus Grissom

Let's see — 2:22 elapsed. Carnarvon comes up in about a minute.

Pete Conrad (CapCom)

Molly Brown, Molly Brown, Carnarvon CAP COM. How do you read?

Gus Grissom

Carnarvon, this is Molly Brown. Read you loud and clear.

Pete Conrad (CapCom)

Very good, Gus; we'd like to get a blood pressure on the co-pilot, please, and could I have your status?

Gus Grissom

Okay — blood pressure's coming and our status is green.

Pete Conrad (CapCom)

Very good. We don't have any communications with the Cape at this time, but they have requested for me to run down your flight control problem a little bit. The first thing I'd like to know is what kind of rates are you getting if you just let it yaw?

Gus Grissom

They are very slow, Pete. Probably on the order of a quarter of a degree per second.

Pete Conrad (CapCom)

Okay and you are in a horizon scan mode, is that correct?

Gus Grissom

At the present time I'm in Pulse and alining the platform.

Pete Conrad (CapCom)

Okay. You're in pulse alining the platform. Are your ACME logic yaw rate gryos and attitude drivers and all that stuff still primary?
