John Glenn

That's affirmative.

CAPCOM

Good in all axes. Over.

John Glenn

That is affirmative

CAPCOM

Can you give status on your ASCS system? Over.

John Glenn

This is Friendship Seven. ASCS started out operating, it would drop into orientation mode in yaw and that would throw the other axes out. It was doing this for a while it world drift off slowly, yaw right and there would be no correction until it went out about 20° . Then it would come rapidly back across and correct itself from a 20° right attitude, would come back across to a left attitude in orientation mode. This continued for a while. I took control, that was right after Guaymas. By the time I had gone over Africa the condition had just reversed, had just reversed. The same thing, only the other direction. Over.

CAPCOM

Roger, I understand.

CAPCOM

Friendship Seven, if you're ready, could we conduct this 30 minute report? Over.

Automatic fuel is still on. Retro-Delay, normal, Landing Bag is off. Everything else on sequence panel is normal. Fuel. …

CAPCOM

Could we have a blood pressure check? Start your button, then exercise the bungee cord, then start your blood pressure check again. Over.

Roger. Friendship Seven. Blood pressure coming on.

CAPCOM

Roger, Friendship Seven. We're reading your blood pressure, what kind of result on your visual acuity test? Over.

Attitudes at present time on manual control are roll 5 [degrees] right, yaw 15 [degrees] right, pitch —34 [degrees] in orbit attitude. My time from launch is 2 plus 33 plus 60, MARK! Correction that would be 2 plus 34 on that mark. Did you receive? Over.

John Glenn

This is Friendship Seven. All these little particles; there are thousands of them; and they're not coming from the capsule. They're something that's already up there because they're all over the sky. Way out I can see them, as far as I can see in each direction almost.

CAPCOM

Roger, Friendship Seven.

John Glenn

Friendship Seven, I have no sensations at all from weightlessness except very pleasant. No ill effects at all, I'm not sick; feel fine. I have had no, no dizziness: I've run the head checks, the head movements and have no problem with that. I've run the oculogyric check and have no problem with that. I haven't been able to use much of the equipment this orbit, however. I've been mainly concerned with this control problem. Over.
