John Glenn

Roger, going to UHF.

CAPCOM

Friendship Seven, Muchea Cap Com. How now? Over.

CAPCOM

Friendship Seven, this is Muchea Cap Com. How are read now? Over.

John Glenn

Hello, Muchea. Friendship Seven. Read you loud and clear; how me?

CAPCOM

Loud and clear. You were coming in slightly garbled. Could you give us your fuel, oxygen and amps? Over.

John Glenn

Roger. Fuel, 60-85 [percent]; oxygen, 65-100 [percent]; amps, 22. Over.

CAPCOM

Roger. Exhaust temperature?

John Glenn

Exhaust temperature 50 [degrees]. Over.

CAPCOM

Roger. Are you in fly-by-wire?

John Glenn

Negative, I am on manual at present time. I'm down to 60 [percent] on automatic fuel, so I cut it off and I'm on manual at present time. Over.

CAPCOM

Roger. How is your yaw thruster problem? Over.

John Glenn

This is Friendship Seven. I am getting some erratic indications in all axes. When I align everything on orbit attitude by the instruments I am considerably off where I should be. I'm rolled some 20° to the right; I'm also yawed to the right a little bit. Over.

CAPCOM

Roger, understand. Are you satisfied with the fly-by-wire and manual proportional systems? Over.

John Glenn

Fly-by-wire is not functioning in yaw low right. Over.

CAPCOM

Roger, low yaw right.

John Glenn

That's affirmative. When I first had trouble with it, it was malfunctioning in low yaw left, and now low yaw left is operating okay, but low yaw right is not operating. Over.

CAPCOM

Roger. Have you tried caging your gyros and re-erecting them. What do you think about this? Over.

John Glenn

Negative, have not yet. I want to get an alignment as soon as I get back in daylight and do just exactly that. I think my, I'm probably not—my scanners are probably not working right. Over.

CAPCOM

Roger. Will you confirm the Landing Bag switch is in the off position? Over.

John Glenn

That is affirmative. Landing Bag switch is in the center off position.

CAPCOM

You haven't had any banging noises or anything of this type at higher rates?

CAPCOM

They wanted this answer. Do you have your retrosequence times 2 Dog, Easy, and Golf from Indian Ocean Ship?

John Glenn

Standby one. Yes, 2 Easy, and Golf, yes, I do have those.

CAPCOM

Do you have any, are you ready for Z and R Cal? Over.

John Glenn

Affirmative, go ahead.

CAPCOM

Cal coming through.

CAPCOM

Any comments on weightlessness, etc.

John Glenn

Negative, I have no ill effects whatsoever. I don't even really notice it now. I'm just, very comfortable.

John Glenn

I have the constellation of Orion up here in the window now. I'm holding a position on it.

CAPCOM

Roger, good. Your 150 VA is 200 [degrees]; your 250 VA is 190 [degrees]. Over.

CAPCOM

R Cal, coming now.

CAPCOM

Friendship Seven, Muchea Cap Com. Do you still have high, both high thrusters in fly-by-wire? Over.

John Glenn

That's affirmative, I do.

CAPCOM

Friendship Seven, Woomera Cap Com. We have contact, TM solid and UHF solid. Over.

CAPCOM

Friendship Seven, are you ready to go ahead with this 30-minute report? Over.

John Glenn

Negative, not just at the moment. Stand by.

CAPCOM

Roger, Friendship Seven.

CAPCOM

Friendship Seven, Muchea. Just a reminder to take your exercise after the blood pressure. Over, Woomera.

CAPCOM

Friendship Seven, Woomera Cap Com. Do you read? Over.

John Glenn

Go ahead, Woomera.

CAPCOM

The Cape advises that you conduct this horizon check and cage the gyros, before California.

John Glenn

Say again, please, Woomera, did not understand.

CAPCOM

Cape advises that you conduct this horizon check, and cage the gyros before California contact. Over.

John Glenn

Roger, understand before California contact.

CAPCOM

Roger. Would like to confirm your control systems status, fly-by-wire low yaw right is inoperative.

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.

John Glenn

Friendship Seven. Roger. All switch fuses still same position. Squib is armed. Auto Retrojettison is off. ASCS mode selector is normal, rate command, gyro, normal. Manual fuel handle is pulled. 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.

John Glenn

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.

John Glenn

Roger. Friendship Seven. Visual acuity still good. Can read same lines I did when starting out. Over.

CAPCOM

Roger. Would like to go through this 30-minute report again, starting with the Auto Retro-jett switch. Go ahead.

John Glenn

Auto Retro-jettison is armed. I'm having to break this in the middle because I need to keep looking out the window to control accurately. Over.

CAPCOM

Roger, Friendship Seven. … discussion. Over.

John Glenn

This is Friendship Seven. Auto Retro-jettison is off. ASCS mode selector is normal, rate command, gyro normal. All “T” handles are in except manual, and it is out. I am controlling manually at present time. Landing Bag switch is off. Sequence panel is all normal except for that. The control fuel is 60-82 [percent]. 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

Roger. Cabin pressure is 5.5 and holding. Cabin air is 95 [degrees]. Cabin excess water light is still on. I'm turning it down a little bit more yet.

John Glenn

Cabin relative humidity is indicating 20 [percent]. Coolant quantity is 66 [percent]. Suit is 68 [degrees] on temperature, pressure 5.8 indicated, steam temperature, 50 [degrees] in suit circuit and comfortable. Oxygen is 65-100 [percent] amps 20. Voltages: main 24, 25, 25, 25; standby one is 25, 25; isolated 29; and back on main. Fans is 113, ASCS 113. I have two warning lights on, the excess cabin water and fuel quantity. Over.

CAPCOM

Roger, Friendship Seven. Aeromed would like to know whether you have conducted your exercise on bungee cord. Over.

John Glenn

Negative, I have not done that recently. Will conduct that now as part of this check. You had a blood pressure.

CAPCOM

You are fading now. Standby for Canton in a few minutes. This is Woomera Cap Com, Over and Out.

John Glenn

Okay, exercise conducted. Blood pressure starting.

John Glenn

This is Friendship Seven. Woomera, are you still receiving me? Over.

John Glenn

This is Friendship Seven.

Comm Tech

Friendship Seven, Canton Com Tech.

John Glenn

Hello Canton Com Tech. Friendship Seven. How did you receive UHF-HI? Over.

Comm Tech

Friendship Seven, Canton Com Tech. Reading you loud and clear. Standby for Cap Com.

John Glenn

Roger. Canton Cap Com, Friendship Seven. Fuel 62-75 [degrees], oxygen 65-98 [percent], correction 65-100 [percent], amps 23. My condition is good. The sunrise is coming around the capsule right now. Over.

CAPCOM

Roger, Friendship Seven. This is Canton. We have TM solid; go ahead, Over.

John Glenn

Roger. This is Friendship Seven, and now that the sunrise is starting, I have all these little particles coming around the capsule again, just at sunrise.

CAPCOM

Roger, Friendship Seven.

John Glenn

I also can see the light on my, on steam from the thruster when I operate it. Over.

CAPCOM

Roger, Friendship Seven. Are, are your thrusters working, are all your high thrusters working okay. Over.

John Glenn

This Friendship Seven. Affirmative, operating okay.

John Glenn

This is Friendship Seven. I think my, I can see a little bit of steam spitting against the dark sky here occasionally from my pitch down manual thruster. 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.

CAPCOM

Friendship Seven, this is Canton. Our telemetry here indicates that everything is okay. Over.

John Glenn

Roger, Friendship Seven.

CAPCOM

Friendship Seven, this is Canton. Our Aeromed would like to hear any comments you have on weightlessness, nausea, dizziness, taste and smell sensations. Over.

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.

CAPCOM

Roger, Friendship Seven. Our fuel quantities here agree with yours. Our 150 fans inverter temperature is 200 [degrees]. The ASCS temperature is 190 [degrees]. Out

John Glenn

Roger, Friendship Seven.

CAPCOM

Friendship Seven, this is Canton. Do you have all the retro times that you need? Over.

John Glenn

This is Friendship Seven. I believe so. I have Foxtrot coming up here, I mean Golf coming up, at 03 00 39. Is that affirm?

John Glenn

This is Friendship Seven. I'm trying to get some pictures of these particles that are outside here. Over.

CAPCOM

Friendship Seven, that time we have for Golf is 03 00 39. Over.

CAPCOM

Friendship Seven, this is Canton. We also have no indication that your landing bag might be deployed. Over.

John Glenn

Roger. Did someone report landing bag could be down? Over.

CAPCOM

Negative, we had a request to monitor this and to ask you if you heard any flapping, when you had high capsule rates. …

CAPCOM

… this was. Over.

John Glenn

Well, I think they probably thought these particles I saw might have come from that, but these are, there there are thousands of these things, and they go out for, it looks like miles in each direction from me and they move by here very slowly. I saw them at the same spot on the first orbit. Over.

CAPCOM

Friendship Seven, what control mode are you in presently?

John Glenn

This is Friendship Seven. I am in manual. While on the dark side, I aligned myself with the horizon, when up to 0 0 0, and caged the gyros and uncaged again. Over.

CAPCOM

Roger, Friendship Seven. Will be losing contact any minute now, you have reentry checks to make and approximately 10 minutes, until California contact. Over.

John Glenn

Roger, Friendship Seven.

Comm Tech

Friendship Seven, this is Hawaii Com Tech on UHF and HF. How do you read? Over.

John Glenn

Say again, Com Tech, what station?

Comm Tech

Friendship Seven, Hawaii Com Tech on UHF and HF. How do you read? Over.

John Glenn

Hello Hawaii. Loud and clear; how me? Over.

John Glenn

Hello Hawaii. Friendship Seven. Loud and clear; how me? Over.

CAPCOM

Friendship Seven, this is Hawaii Cap Com, I read you loud and clear. What is your status report? Over.

John Glenn

Roger, Friendship Seven, ah.

G

He has contact, we're putting air-to-ground on.

John Glenn

This is Friendship Seven. Fuel 62-74 [percent], oxygen 64-98 [percent], amps 23. Over.

CAPCOM

Roger, Friendship Seven. The first part of your transmission was broken up; could you say again, fuel?

John Glenn

Roger, fuel 62-74 [percent]. Over.

CAPCOM

Roger. Read 62-74 [percent], Friendship Seven. Cape would like to know if you have made the visual check on the gyros yet?

John Glenn

This is affirmative. During the dark side I went to 0 0 0 as best I could and caged and uncaged the gyros. I'm rechecking this at present time. Over.

CAPCOM

Roger. I'll stand by until you complete your checks and we'd like to get the results.

John Glenn

Roger, Friendship Seven.

John Glenn

Hawaii, this is Friendship Seven. Are we getting scanner ignore? Over.

CAPCOM

There are no ignore indications on the ground as of now, Friendship Seven. Hawaii. Over.

John Glenn

Roger. This is Friendship Seven. When I aligned in, standby one.

John Glenn

This is Friendship Seven. Roll appears to be about 20° off. At present time, I am indicating 20° right roll when I am lined up perfectly with the horizon. Over.

CAPCOM

Roger, Friendship Seven. Understand you still have a 20° error in your attitude indication after caging the gyros.

John Glenn

This is Friendship Seven. That's affirmative. It's drifted off again. It was correct at that time; it apparently has drifted off. It's about 20° off in roll.

CAPCOM

Friendship Seven, could you give us a readout on all three axes; we'd like to compare ground readouts.

John Glenn

Roger, Friendship Seven. Roll indicates 19 [degrees] right, yaw, 2 [degrees] left, pitch —22 [degrees]. Over.

CAPCOM

Roger, Friendship Seven. Read you loud and clear.

John Glenn

Friendship Seven, Hawaii Cap Com. Can you estimate the drift rates you are getting?

John Glenn

This is Friendship Seven. Drift rates are very difficult to pick up for some reason. I have not been able to get real accurate drift rates. I feel that. …

CAPCOM

Do you still consider yourself GO for the next orbit?

John Glenn

That is affirmative, I am GO for the next orbit.

CAPCOM

Roger, I understand. At present time ground concurs.

CAPCOM

Could you, could you give me a readout on exhaust temperature, please?

John Glenn

Friendship Seven. Roger. Exhaust temperature, 47 [degrees].

CAPCOM

Friendship Seven, Hawaii Cap Com. Could you read exhaust temperature please?

John Glenn

Roger. Exhaust temperature 47 [degrees].
