Friendship Seven, this is Indian Cap Com. Do you have any feelings from weightlessness? Over.

John Glenn

This is Friendship Seven. Negative, I feel fine so far. Over.

CAPCOM

Roger, understand.

John Glenn

This is Friendship Seven. Turning suit water to increase position. I am still running steam temperature of about 60 [degrees.] Over.

CAPCOM

Roger, understand.

John Glenn

I am now on suit temperature setting of 1.7. Over.

CAPCOM

Roger, understand. What is your control mode? Over.

John Glenn

Control mode is ASCS automatic. Over.

CAPCOM

Roger, understand.

John Glenn

Roger. The night side is light enough; I can even see the horizon okay out through the periscope. Over.

John Glenn

Friendship Seven, Roger.

CAPCOM

Friendship Seven, this is Indiana CapCom. We now have IOS. Over.

John Glenn

Roger, understand IOS.

CAPCOM

Your voice transmissions are starting to fade very badly. Over.

John Glenn

Roger. Friendship Seven.

CAPCOM

… clear, IOS Cap Com. Out.

John Glenn

This is Friendship Seven, broadcasting in the blind. Wait a minute. Friendship Seven, broadcasting in the blind, making observations on night outside. There seems to be a high layer way up above the horizon; much higher than anything I saw on the daylight side. The stars seem to go through it and then go on down toward the real horizon. It would appear to be possibly some 7 or 8 degrees wide. I can see the clouds down below it; then a dark band, then a lighter band that the stars shine right through as they come down toward the horizon. I can identify Aries and Triangulum.

Comm Tech

Friendship Seven, Muchea Com Tech. We read you. Would you.

John Glenn

Hello, Muchea Com Tech. This is Friendship Seven, reading you loud and clear. How me?

CAPCOM

Roger, Friendship Seven. Muchea Cap Com. How me? Over.

John Glenn

Roger. How are you doing Gordo? We're doing real fine up here. Everything is going very well. Over.

CAPCOM

John, you sound good.

John Glenn

Roger. Control fuel is 90-100 [percent], oxygen is 75-100 [percent], amps are 22, all systems are still go. Having no problems at all. Control system operating fine. Over.

CAPCOM

Roger. Do you have any star or weather or landmark observations as yet? Over.

John Glenn

Roger. I was just making some to the recorder. The only unusual thing I have noticed is a rather high, what would appear to be a haze layer up some 7 or 8 degrees above the horizon on the night side. The stars I can see through it as they go down toward the real horizon, but it is a very visible single band or layer pretty well up above the normal horizon. Over.

CAPCOM

Roger, very interesting.

John Glenn

This is Friendship Seven. I had a lot of cloud cover coming off of Africa. It has thinned out considerably now and although I can't definitely see the ocean, there is a lot of moonlight here that does reflect off what clouds there are. Over.

CAPCOM

Roger. You had an excellent cutoff, John. Your velocity was 8 feet per second low. V over VR, 1.0002. Can you confirm your retrosequence 1 Easy, Foxtrot, and Hotel from Indian Ocean Ship? Over.

John Glenn

That is affirmative. I did.

CAPCOM

Roger. Your yaw check over ATS was good. Your yaw when you were on fly-by-wire over IOS was excellent.

CAPCOM

Are we clear to send you a Z and R Cal? Over.

CAPCOM

Z Cal coming through now.

CAPCOM

Roger. Shortly you may observe some lights down there. You want to take a check on that to your right? Over.

John Glenn

Roger. I'm all set to see if I can't get them in sight.

CAPCOM

Roger. You do have your visor closed at this time. Over.

John Glenn

This is affirmative. I had it open for a little while; it's closed now. Cabin pressure is holding in good shape. Over.

CAPCOM

Roger, Z Cal is off. R Cal is coming through now.

CAPCOM

Any symptoms of vertigo or nausea at all? Over.

John Glenn

Negative, no symptoms whatsoever. I feel fine. Over.

CAPCOM

Roger. Your 150 VA inverter is 180°. Looks like it's doing pretty well.

John Glenn

That was sure a short day.

CAPCOM

Say again, Friendship Seven.

John Glenn

That was about the shortest day I've ever run into.

CAPCOM

Kinda passes rapidly, huh.

CAPCOM

Okay. Do you have any landmark, any other landmark observations to make? Over.

John Glenn

This is Friendship Seven. I have the Pleiades in sight out here, very clear. Picking up some of these star patterns now. Little better than I was just off of Africa.

CAPCOM

Roger, understand you have Pleiades in sight. Have you sighted Orion yet? Over.

John Glenn

Negative. Do not have Orion in sight yet.

CAPCOM

Within a few seconds, you should have Orion and Canopus and Sirius probably in sight very shortly thereafter. The moon will be off. …

CAPCOM

Do you have time to send us a blood pressure reading? Over.

CAPCOM

Roger. The surgeons are standing by for your blood pressure whenever you're ready.

John Glenn

Roger. I'm already sending it. Did they pick it up? Over.

CAPCOM

Roger. They have it in good shape.

John Glenn

Roger. I do have the lights in sight on the ground. Over.

CAPCOM

Roger. Is it just off to your right there?

John Glenn

That's affirmative. Just to my right I can see a big pattern of lights apparently right on the coast. I can see the outline of a town and a very bright light just to the south of it. On down. …

CAPCOM

Perth and Rockingham, you're seeing there.

John Glenn

Roger. The lights show up very well and thank everybody for turning them on, will you?

CAPCOM

We sure will, John.

John Glenn

Very fine. On down farther to the south and inland, I can see more lights. There are two, actually four patterns in that area. And also, coming into sight in the window now is another one almost down under me. The lights are very clear from up here.

CAPCOM

Roger. Sounds good.

John Glenn

This is Friendship Seven. Opening visor, going to eat. Over.

CAPCOM

Roger, Friendship Seven.

John Glenn

This is Friendship Seven. Having no trouble at all eating, very good. In the periscope, I can see the brilliant blue horizon coming up behind me; approaching sunrise. Over.

CAPCOM

Roger, Friendship Seven. You are very lucky.

John Glenn

You're right. Man, this is beautiful

John Glenn

This is Friendship Seven. Have eaten one tube of food, shutting the visor. I've had no problem at all eating. Oh, the sun is coming up behind me in the periscope, a brilliant, brilliant red. Over.

John Glenn

This is Friendship Seven. It's blinding through the scope on clear. It's started up just as I gave you that mark; I'm going to the dark filter to watch it come on up.

John Glenn

This is Friendship Seven. I'll try to describe what I'm in here. I am in a big mass of some very small particles, that are brilliantly lit up like they're luminescent. I never saw anything like it. They round a little; they're coming by the capsule, and they look like little stars. A whole shower of them coming by.

John Glenn

They swirl around the capsule and go in front of the window and they're all brilliantly lighted. They probably average maybe 7 or 8 feet apart, but I can see them all down below me, also.

CAPCOM

Roger, Friendship Seven. Can you hear any impact with the capsule? Over.

John Glenn

Negative, negative. They're very slow; they're not going away from me more than maybe 3 or 4 miles per hour. They're going at the same speed I am approximately. They're only very slightly under my speed. Over.

John Glenn

They do, they do have a different motion, though, from me because they swirl around the capsule and then depart back the way I am looking.

John Glenn

Are you receiving? Over.

John Glenn

There are literally thousands of them.

John Glenn

This is Friendship Seven. Am I in contact with anyone? Over.

John Glenn

This has been going on since about 1 plus 15. Over. Just after I remarked about the sunset. I looked back up and looked out the window, and all the little swirl of particles was going by. Over.

John Glenn

This is Friendship Seven. This is Friendship Seven, broadcasting in the blind again on HF.

John Glenn

This is Friendship Seven, broadcasting in the blind. Sunrise has come up behind in the periscope. It was brilliant in the scope, a brilliant red as it approached the horizon and came up; and just as the—as I looked back up out the window, I had literally thousands of small, luminous particles swirling around the capsule and going away from me at maybe 3 to 5 miles per hour. Now that I am out in the bright sun, they seem to have disappeared. It was just as the sun was coming up. I can still see just a few of them now, even though the sun is up some 20° above the horizon.

Comm Tech

Friendship Seven, Friendship Seven. This is Guaymas Com Tech, Guaymas Com Tech, transmitting on HF-UHF. Do you read? Over.

CAPCOM

Friendship Seven, Guaymas Cap Com. Say again, please. Over.

John Glenn

This is Friendship Seven. Just as the sun came up, there were some brilliantly-lighted particles that looked luminous, that were swirling around the capsule. I don't have any in sight right now; I did have a couple just a moment ago, when I made the transmission to you. Over.

CAPCOM

Roger, Friendship Seven.

John Glenn

This is Friendship Seven. For the record, number, the number two film that I'm putting in the camera is the number four roll.

John Glenn

Roger, 04 plus 32 plus 40 for Hotel.

CAPCOM

Friendship Seven, Guaymas. If you have a chance, could you give us a blood pressure check? Over.

John Glenn

Roger. Friendship Seven. Will give blood pressure check. I still have some of these particles that I cannot identify coming around the capsule occasionally. Over.

CAPCOM

Roger. How big are these particles?

John Glenn

Very small, I would indicate they are on the order of 16th of an inch or smaller. They drift by the window and I can see them against the dark sky. Just at sunrise there were literally thousands of them. It looked just like a myriad of stars. Over.

CAPCOM

Roger. Are they moving by you or floating with you? Over.

John Glenn

Some of them almost float with me. Most of them appear to be moving at about 3 to 5 miles an hour away from me. I'm going just a little faster then they are. Over.

CAPCOM

Friendship Seven, Guaymas Cap Com. We have a scope retract indication on ground. Believe it's ground failure. Over.

John Glenn

This is Friendship Seven. Affirmative. Seems to be controlling now. There may be some drift to the right, however. Over.

John Glenn

This is Friendship Seven. It drifts about out 20° to the right and then gets a large pulse to kick it back over to the left. It goes in about, the rate runs over to about 3 degrees per second, to the left.

John Glenn

It's drifting again in yaw. Over. And once again pulls through.
