APPENDIX [77-107]

MA-7 AIR-GROUND VOICE COMMUNICATIONS [4/6]

 

ZANZIBAR (SECOND PASS)

 

Time Speaker Dialogue

02 04 03.5

P

Roger, Zanzibar. Loud and clear. How do you read Aurora Seven?

02 04 17

CT

Aurora Seven, Aurora Seven, this is Zanzibar Com Tech, transmitting on HF/UHF. Do you copy? Over.

02 04 26

P

Roger. Loud and clear. How me, Zanzibar?

02 04 31

CT

Aurora Seven, Aurora Seven, this is Zanzibar Cap Com. Read you weak but readable. Do you have a short report for us?

02 04 38.5

P

Roger. My status is good; the capsule status is good; my control mode is automatic; gyros are normal; maneuver is off. Control fuel is 51 [percent] and 69 [percent]; oxygen is 82 [percent] and 100 [percent]. That's about all except I have, so far, been unable to get my suit steam vent temperature down much below 70 [degrees]. Steam vent, or the water control valve setting at this time is 4 at the prelaunch mark. It may be too high. Turning it off at this time and going to three, which is where the cabin is set. Over.

02 05 40

CC

Aurora Seven, Zanzibar Cap Com. Roger, Roger. Do you have the latest-contingency area times?

02 05 49

P

Roger, I have them.

02 05 51

CC

Very good. Are you going to start your balloon test?

02 05 55

P

The balloon is out. I don't see any reason for not leaving it on through the dark side, and I just saw a particle going by at about 2 or 3 feet per second.

02 06 13

CC

Roger, understand. According to flight plan, you're supposed to go to FBW about now, and he says you're on auto mode and I wondered if you plan to go through with this. Over.

02 06 25.5

P

That is negative. I think that the fact that I'm low on fuel dictates that I stay on auto as long as the fuel consumption on automatic is not excessive. Over.

02 06 39.5

CC

Roger, Aurora Seven. Congratulations on your trip so far and I'm glad everything has gone....

02 06 44.5

P

Thank you very much.

02 06 50.5

P

I now have the wide, blue horizon band. It looks to be, at this time Capsule elapsed 02 0700, to be about the diameter underneath the sun. It seems to be the same thickness underneath the sun as the sun's diameter. North and south it becomes less distinct and lighter. It extends up farther from the horizon.

02 07 29.5

CC

Roger. Aurora Seven. That's a hard one to pronounce, anything that we can do for you....

02 07 38

P

Negative. I think everything is going quite well.

02 07 41.5

CC

Roger. We'll be waiting. Out.

02 07 43.5

P

Roger. See you next time.

 

INDIAN OCEAN SHIP (SECOND PASS)

 

Time Speaker Dialogue

02 07 48

CC

Aurora Seven, this is Indian Ocean Ship. Over.

02 07 50.5

P

Roger, Indian Cap Com. Loud and clear. Flow me?

02 07 54.5

CC

Roger. Loud and clear. We have had transmitter trouble on your previous run. We just got a message from the Cape . . ., to conserve fuel. I monitored part of your transmission to Zanzibar and understand . . . the situation.

02 08 12.5

P

That is Roger.

02 08 14.5

CC

Do you have retrosequence times for 2 Delta, 2 Echo and Golf?

02 08 19

P

That is negative. I have the nominals.

02 08 23.5

CC

Roger 2 Delta and 2 Echo are still nominal. Area Golf is 03 00 29, 03 00 29.

02 08 35

P

Roger. 03 00 29.

02 08 39

CC

Roger, Aurora Seven, I read you loud and clear. Do you have any comments for the . . . Ocean?

02 08 46.5

P

That is Roger. I believe we may have some automatic mode difficulty. Let me check fly-by-wire a minute.

02 09 07

P

All thrusters are okay.

02 09 11

CC

Roger.

02 09 17.5

P

However, the gyros do not seem to be indicating properly.

02 09 25.5

CC

Roger.

02 09 27

P

And that is not correct either. The gyros are . . . are okay; but on ASCS standby. It may be an orientation problem. I'll orient visually and . . . see if that will help out the ASCS problem.

02 10 11.5

CC

Aurora Seven from Indian Cap Com. Your blood pressure on your . . . fairly high and you are supposed to, if possible, give a blood pressure over Indian Ocean Ship.

02 10 23.5

P

Roger. I've put blood pressure up on the air already. Over.

02 10 29.5

CC

Say again, Aurora.

02 10 31

P

Blood pressure is on the air now.

02 10 35

CC

Roger.

02 10 40

S

Blood pressure is coming through fine.

02 10 42.5

CC

your blood pressure is coming through fine.

02 10 44.5

P

Roger.

02 10 58

CC

Aurora Seven, this is Indian Cap Com. We have lost telemetry contact. How do you read me? Over.

02 11 04.5

P

Roger. Still reading you okay.

02 11 07.5

CC

. . . report to Cape you have checked fly-by-wire and all thrusters are okay. Is there anything else?

02 11 13

P

That is negative Except this problem with steam vent temperature. I'm going-I'll open the visor a minute; that'll cool-it seems cooler with the visor open.

02 11 26

CC

Roger. Did you take xylose?

02 11 28.5

P

That is negative I will do so now

02 11 35

CC

Roger.

02 11 45

CC

Aurora Seven, confirm you've checked fly-by-wire and all thrusters okay.

02 11 51.5

P

Roger. Fly-by-wire is checked; all thrusters are okay.

02 11 56

CC

Roger.

02 12 28

CC

Aurora Seven, Indian Ocean Cap Com. I do not read your transmission.

02 12 32

P

Roger. Indian Cap Com, Aurora Seven

02 12 35.5

CC

Out.

02 15 11.5

P

Well, I have-I am in record only, and I am getting warm now.

02 15 34

P

Don't know what to with the cabin.

02 15 45

P

I'll turn it up and see what happens.

02 16 04.5

P

I have gotten badly behind in the flight plan now.

02 17 06

P

Okay, evaluating capsule stability at this time. The capsule is most stable.

02 17 24

P

I seem able to put it at zero rates. All right, I will do that now. At capsule elapsed 02 17 32, I will zero out all rates.

02 17 45

P

That's as close to zero as I can make it. At 02 17 49, my rates are zero and attitudes are zero plus, or at zero, minus 3, minus 48. Let those rest awhile, and I'll see what we can do about suit temperature.

02 18 14

P

Cabin is rising. Suit temperature seems to be rising too. I'm going to let it go out until 02 25 00 to see if this is going to bring it down some.

02 18 49

P

I don't need to exercise. I really don't feel I need the exercise. I would get too warm.

02 19 02

P

We'll be getting to Muchea shortly.

02 19 08.5

P

Have a slight pitch up rate at this time, at 02 19 13. I'll zero that out, now. Fly-by-wire-have a slight yaw left rate-I'll zero out now. Attitudes at this time are minus 30.

02 19 57.5

P

Both busses are okay. All-let's see- number-number two battery is down to 22. One, is 24; three, is 24; standby one and two, are 24; isolated, is 27; main, is 23; main IBU, is 27 Two- two is now up. Main battery number two is up.

02 20 34.5

P

I am over the dark side now. The moonrise has not occurred and although I still see the lighted area from the setting sun behind us..

02 22 16.5

P

Now, I do have the haze layer at this time. It seems to be brighter,than- it's-it's good to open the cabin, open the visor.

02 23 07

P

The reticle now extincts at about 5.6.

 

MUCHEA (SECOND PASS)

 

Time Speaker Dialogue

02 23 21

P

Hello, Muchea Cap Com. Aurora Seven Loud and clear. How me?

02 23 26

P

Read you loud and clear also. What's your status?

02 23 28

P

Roger. My status is good; control mode is fly-by-wire; gyros normal; maneuver off. Fuel is 45-6-70 [percent], that's 45-70 [percent], and oxygen is 84-100 [percent]. I have only one minor problem, and that is my inability to get the suit steam vent temperature down, Deke.

02 23 56.5

P

Roger. What's it running now?

02 23 58.5

CC

Well, I'm reading 70 [degrees]. I'm really a little at a loss as to how to get it down, my suit-water valve is set now past the marks. This doesn't seem to being it down, and neither does putting it . . . negative. That's wrong. The cabin was past the marks The suit temperature is at prelaunch value of about four. I'm going to go to a setting of plus 6 at this time and see if that will bring it down below 70 [degrees]. Over.

02 24 40.5

CC

Okay. Fine. We're indicating 84 [degrees] suit which is a bit high.

02 24 44.5

P

Roger. My gage shows 7,76 [degrees] on the suit.

02 24 50

CC

Rog.

02 24 52

CC

Okay. Let me give you a couple of retrotimes here. You have a 2 Dog nominal; Gold is 03 . . . 29; Hotel 04 32 26.

02 25 10

P

Roger. Understand 26.

02 25 13.5

CC

We're including your clock is still one second slow.

02 25 18.5

P

Roger.

02 25 20

CC

G.m.t. hack of 15 10 42-mark. 3(02 25 25 c.e.t)

02 25 26

P

Roger. I'm right on and so is the backup.

02 25 29.5

CC

Roger. Would you send us a blood pressure, please?

02 25 33.5

P

Starting. Roger. Starting now.

02 25 53.5

CC

What mode of communications arc you using at this time?

02 25 58.5

P

I am on UHF high, Deke.

02 26 01

CC

Fine. Roger. Would you try using your mike button once instead of your VOX. See how this comes in.

02 26 05.5

P

Roger. Soon as I get through the blood pressure. I can do it now.

02 26 11.5

P

This is using the push to talk. 1, 2, 3, 4, 5, 4, 3, 2, 1. How now?

02 26 18

CC

I see no difference. They're identical.

02 26 20

P

Roger, is the modulation pretty good?

02 26 23

CC

Very good.

02 26 24

P

Roger.

02 26 26

P

Capsule stability, Deke, is very, very, good. I've noticed that I can put in a 1-degree-per second rate on the needle just by moving heads and arms,-my head and arms. Over.

02 26 42

CC

Very good, excellent. For your information, there will be no flares at Woomera on this pass, since the cloud cover won't allow you to see them anyway.

02 26 50

P

Roger. I was unsuccessful last pass.

02 26 55.5

CC

Okay, I'm going to send you a Z cal at this time.

02 26 59

P

Roger.

02 27 02.5

CC

Mark!

02 27 15.5

CC

Z cal is coming off.

02 27 17.5

P

Roger.

02 27 18.5

CC

On with R cal.

02 27 20

P

Roger.

02 27 33

P

Blood pressure stop.

02 27 34.5

CC

Blood pressure stop. Okay, we're going to oscillate R cal a couple of times here in attempt to reset our temperature problem.

02 27 41.5

P

Roger.

02 27 47

CC

Okay, R cal off. We suggest you go to manual at this point and preserve your auto fuel. Low at this point.

02 27 53.5

P

Roger. Going to manual now.

02 27 57

CC

Roger.

02 28 00.5

P

At this time I'm reading 45 70 [percent] on fuel.

02 28 04.5

CC

Rog. Understand 45-70 [percent].

02 28 07

P

Cabin temperature is 107 [degrees].

02 28 10.5

CC

Cabin 107 [degrees].

02 28 17.5

CC

I don't believe you've ever received any sunrise, sunset times.

02 28 23

P

Roger. Give me the whole lot of them, Deke, or the ones that are coming. Give me rise, set, and rise.

02 28 32

CC

Roger. Will do. Your next sunrise will be 02 50 00.

02 28 40

P

Roger. Copy.

02 28 41.5

CC

Sunset 03 41 20.

02 28 47

P

Roger.

02 28 48.5

CC

Sunrise 04.19 00.

02 23 54.5

P

Roger. Copy.

02 28 59

CC

Well, it sounds like you're doing real well up there, Dad.

02 29 01.5

P

Roger. It's a little warm.

02 29 04

CC

I suspect so.

02 29 09

CC

Been riding your horse the last couple of days.

02 29 12

P

Good.

02 29 23.5

CC

For your information, Cape informs that if we don't stay on manual for quite a spell here we'll probably have to end this orbit.

02 29 31

P

I'll be sure and stay on manual.

02 29 33.5

CC

Roger.

02 29 35.5

CC

You've got a lot of drift left here yet too.

02 29 38.5

P

Say again.

02 29 40

CC

You've got drift capability left yet, too.

02 29 41.5

P

Roger.

02 29 47.5

CC

Did you see any lights over the Australian . . .?

02 29 50.5

P

I did. That is, Roger. I did see some lights. I couldn't identify them, however.

02 29 57.5

CC

Roger. Understand.

02 30 05.5

CC

Would you give us another readout on your suit steam temp? Has this changed any?

02 30 09.5

P

It may have gone down just a tad. It's about zero now; I mean about 70 [degrees] now. It was a little bit higher. The visor is closed and I'm beginning to feel a little cooler.

02 30 24

CC

Very good.

02 30 27

CC

We indicated 2-degree drop at suit inlet, so it sounds like you're making out a bit.

02 30 30

P

Roger. My control mode now, Deke, is manual; gyros free; and the maneuver is off.

02 30 41.5

CC

Roger. I understand. Manual; gyro free; and maneuver off.

02 30 44.5

P

Roger.

02 31 23.5

CC

Aurora Seven, this is Muchea Cap Com. Are you reading?

02 31 26

P

Still reading, Muchea.

02 31 28

CC

Very good.

02 31 30

CC

We are just kind of leaving you alone. How is your balloon doing, incidentally?

02 31 33.5

P

I haven't found it since it got dark. It's-it's-it rambles quite a bit, Deke. It's not inflated fully, and it doesn't stretch out on the line tight like I expected. It bounces in and out and oscillates up and down and sideways. Have no good tensiometer readings yet.

 

WOOMERA (SECOND PASS)

 

Time Speaker Dialogue

02 32 08

CC

Aurora Seven, Aurora Seven, this is Woomera Cap Com. How do you read? Over.

02 32 12

P

Hello, Woomera. Aurora Seven. Loud and clear. How me?

02 32 17

CC

Roger. You are loud and clear, also.

02 32 20.5

CC

We copied your transmission over Muchea. Understand you still have the balloon on. Is that an affirmative?

02 32 26

P

That is affirmative. I have the balloon on. However, I haven't seen it for some time. It wanders quite a bit and I do not have it in sight at this moment. I believe that-it might be visible against the earth background at this time.

02 32 49

CC

Roger. Do you see the moon at all?

02 32 52

P

I am faced the wrong way and limited in maneuverability I have left because of my fuel state. I can see the terminator between moonlit side, and unmoonlit side. Over.

02 33 08.5

CC

Roger. Understand.

02 33 15

CC

You are manual control. Is that right?

02 33 16.5

P

That is correct. My control mode is manual; gyros free; maneuver off. Over.

02 33 22.5

CC

Roger. Could you give us . . . could you give us cabin temperature?

02 33 31.5

P

Roger. Cabin temperature is 102 [degrees] at this time.

02 33 37

CC

Roger. What is the suit temperature?

02 33 41

P

Okay, stand by.

02 33 49.5

P

Suit temperature is 74 [degrees]; suit steam exhaust is 71 [degrees].

02 33 58.5

CC

Roger. Understand. Are you feeling a little more comfortable at this time?

02 34 02.5

P

I don't know. I'm still warm and still perspiring, but not really uncomfortable. I would like to I would like to nail this suit temperature problem down. It-for all practical purposes, it's uncontrollable as far as I can see.

02 34 26.5

CC

Roger. Understand. You might have to wait a few more minutes before this takes effect. You are on No. 6. Is that right?

02 34 34

P

That is right. Suit temperature is No. 6.

02 34 39

CC

Roger. Systems reports that your suit temperature has dropped 2 degrees over station, if that's any encouragement to you.

02 34 44.5

P

Roger. Thank you. It is.

02 34 46.5

CC

Roger.

02 34 50

CC

Have you taken any food thus far?

02 34 53

P

Yes, I have. However, the food has crumbled badly; and I hate to open the package any more for fear of getting crumbs all over the capsule. I can verify that eating bite-size food as we packaged for this flight is no problem at all. Even the crumbly foods are eaten with no, with no problem.

02 35 20

CC

Roger. How about water?

02 35 22.5

P

I had taken four swallows at approximately this time last orbit. As soon as I get the suit temperature pegged a little bit, I'll open the visor and have some more water. Over.

02 35 37

CC

Roger. You are still coming in very loud and clear.

02 35 43

P

Roger.

02 35 45

CC

. . . out at this time.

02 37 11

P

For the record now-

02 37 32.5

P

One of the labels for a fuse switch has slipped out, and sideways, and has tied the adjoining fuse switch together with it. This happened to emergency-main and reserve-deploy fuse switches.

02 38 06.5

P

I caged the gyros. They are too critical. I will try and navigate on the dark side without the gyros.

02 38 30

P

The fuse switch should be glued in better so that turning off one fuse does not turn off the adjoining one.

02 39 35

P

I guess I'd better try to get that xylose pill out. I hate to do this.

02 40 57.5

P

Oh yes. There is the xylose pill. It didn't melt. All tie rest of the stuff in here did melt.

02 41 31

P

Okay. Xylose pill being consumed at 02 41 35 The rest of the food is pretty much of a mess. Can't stand this cabin temperature.

 

CANTON (SECOND PASS)

 

Time Speaker Dialogue

02 43 39.5

P

Hello, Canton Com Tech. Aurora Seven reads you loud and clear. How me?

02 43 44.5

CC

This is Canton Cap Com. Read you loud and clear. Could you begin your short report, please?

02 43 51

P

Roger, George. My control mode is manual. The gyros are caged, maneuver is off. Fuel is 45 and 64 [percent], a little ahead of schedule. Oxygen reads 82-100 [percent]. Steam vent temperature in the suit is dropping slightly. It's a little below 70 [degrees]. Cabin is 4.6 [psia]. Suit temperature has dropped to about 71 [degrees] now. All the power is good, and here is A blood pressure. Over.

02 44 30

CC

Okay, standing by for blood pressure.

02 44 44

CC

We are receiving the blood-pressure check. Over.

02 44 47

P

Roger.

02 44 50

CC

Do you plan on eating as called for by. ....Over.

02 44 57

P

I did have the visor open a short time ago for the xylose pill. All of the rest of the food that I have aboard has either crumbled or melted. It's unusable in its present state so I think the xylose pill will constitute my last zero g meal. However, the first one, before the food crumbled, was quite easy. It's no problem to eat this bite-size food-in a weightless state. - I also drank some water at that time, which was no problem.

02 45 32.5

CC

Roger. I take it, from what you said then, that you have confirmed that your faceplate is closed for the decision on the third orbit.

02 45 42.5

P

That is correct. My faceplate is closed. Also, what is the trend of my cabin pressure on the ground? Over.

02 45 51

CC

Stand by, please.

02 46 08

CC

We are checking on your request there, Scott. Could you hit that button again? We lost your EKG.

02 46 15

P

Oh, you want blood pressure or EKG?

02 46 17.5

CC

No, we lost the EKG. Possibly you could press on those sensors. Okay, Surgeon informs me that the EKG is now returning. Your other question, cabin pressure is staying at 5.1 [psia] approximately.

02 46 36.5

P

Roger. No change in reading since launch. Is that correct?

02 46 40

CC

Negative on that. It's gone from 5.8 [psia] at launch to approximately 5.1 [psia] in very, very gradual descending trend.

02 46 52

P

Roger. My cabin pressure indicator is reading 4.8 [psia] at this time.

02 47 02

CC

Roger, I have no comment on this, just that the trend appears to be good here on the ground.

02 47 09.5

P

Roger.

02 47 16.5

CC

Do you have any specific comments on your balloon experiments; for example, the best color contrast with the

02 47 36.5

P

Yes, I would say the day-glow orange is the best.

02 47 41

CC

Roger. For your information, the second sunrise should be expected in approximately 3 to 4 minutes.

02 47 47.5

P

Roger, thank you.

02 47 50.5

CC

Everything continues to look very good here on the ground. I've got a reading here on the ground for cabin pressure. This is for your information, is 4.8 [psia]. Now,, this does take the trend that has been set up considerably. The suit pressure comes in at 4.9 [psia].

02 48 10

P

Roger.

02 48 14

CC

We find now that the-the O2 partial pressure is fluctuating slightly, and the-hanging around 4.2 [psia].

02 48 26.5

CC

Did you-?

02 48 29.5

CC

O2 partial pressure is fluctuating-4.2 [psia]-Over.

02 48 35

P

Roger, copied, George, thank you.

02 48 39

CC

As I said before, everything looks very good here. Surgeon is after me here for you to try another blood pressure. Is this convenient?

02 48 47.5

P

Negative. I won't be able to hold still for it now. I've got the sunrise to worry about.

02 48 52.5

CC

Okay. Roger. We have no further queries. If you have any comments we'll be listening down here.

02 49 00
