RESULTS OF THE SECOND U.S. MANNED ORBITAL SPACE FLIGHT, MAY 24, 1962

 

APPENDIX [77-107]

MA-7 AIR-GROUND VOICE COMMUNICATIONS [1/6]

 

The following is a transcript of the MA-7 flight communications taken from the spacecraft onboard tape recording. This is, therefore, a transcription of the communication received and transmitted, as well as some in-flight comments made while in a record-only mode, by the pilot, Scott Carpenter.

The first column shows the ground elapsed time (g.e.t.) from liftoff in hours, minutes, and seconds when the communique was initiated. The communicator is identified, as follows:

 

CC - Capsule (spacecraft) Communicator at the range station

CT-Communications Technician at the range station

F-Flight Director at Bermuda range station

P-Pilot

S-Surgeon or Medical Monitor at the range station

Stony-Blockhouse Communicator

 

All temperatures are given as °F; all pressures are in pounds per square inch, absolute (psia); fuel, oxygen, and coolant quantities are expressed in remaining percent of total nominal capacities; retrosequence times are expressed in g.e.t. (hours, minutes, and seconds).

Within the text, a series of three dots is used to designate times when communiques could not be deciphered. One dash indicates a time pause during a communique. The station in prime contact with the astronaut is designated at the initiation of communications.

00 02 57.5

P

That is. Roger.

00 03 01.5

P

At 3 minutes. Fuel and oxygen are still steady; cabin is holding 5.8 [psia]. Power still looks good; my status is good.

00 03 14

CC

Roger. Pitch minus, minus 2 1/2 [degrees], and you're right on; you're good.

00 03 19

P

Roger. Reading you loud and clear, Gus.

00 03 29

CC

Aurora Seven, . . ., you are good.

00 03 33.5

P

Roger. Still reading you. Broken a little bit. At 30, my status is good. Fuel and oxygen are steady. Cabin is holding 5.8 [psia]; Cabin is holding 5.8 [psia]. Power is good, 25 amps.

00 04 42

CC

Roger, Aurora Seven. You're through 0.8, V over VR of 0.8.

00 04 46

P

Roger. 0.8.

00 05 09

P

Okay, there is SECO. The posigrades fired. I am weightless and starting the fly-by-wire turnaround. Aux Damp is good.

00 05 25.5

CC

Roger. You look good down here.

00 05 27

P

Periscope is out, and

00 05 32

CC

We have a Go, with a 7-orbit capability.

00 05 36

P

Roger. Sweet words.

00 05 38.5

CC

Roger.

00 05 52

P

Okay, turnaround has stopped. I'm pitching down I have the moon in the center of the window, and the booster off to the right slightly.

00 06 07.5

CC

Roger. Understand.

00 06 09.5

P

Fly-by-wire is good in all axes; my pitch attitude is high; coming down now.

00 06 51

CC

Roger. Understand.

00 06 38

P

Roger. The control system on fly-by-wire is very good. I have the booster in the center of the window now, tumbling very slowly.

00 06 50.5

CC

Roger, Aurora Seven. Understand. You sound real good.

00 06 59.5

P

It's very quiet.

00 07 04.5

P

A steady stream of gas, white gas, out of the sustainer engine. Going to ASCS now.

00 07 15

CC

Roger. Understand.

00 07 17

P

ASCS seems to be holding very well. I have a small island just below me.

00 07 26.5

CC

Aurora Seven, standby for retrosequence times.

00 08 21

CC

Roger.

00 08 22.5

P

Roger, I have copied.

00 08 27

P

ASCS looks good, all fly-by-wire thrusters appear to be good in all axes. Going to beginning to unstow the equipment.

00 08 41

CC

Aurora Seven.

00 08 43

P

Roger, and the SECO checklist is complete. She peaked At 6.3 [g's].

00 08 51.5

CC

Cap Com. Over.

00 08 53.5

P

Co ahead, Gus. Loud and clear. How me?

00 09 01.5

CC

Aurora Seven, Cap Com.

00 09 03

P

Roger, loud and clear. How me?

00 09 07

CC

Aurora Seven, Cape Cap Com. Over.

00 09 16

CC

Aurora Seven, Cape Cap Com. Over.

00 09 18.5

P

Loud and clear, Gus. How me?

00 09 25

CC

Aurora Seven, Cape Cap Com. If you read, retro delay to normal?

00 09 29

P

Retro delay normal. Roger.

00 09 32

CC

. . . igee 86 [nautical miles].

00 09 34.5

P

Roger. Copied perigee 86 [nautical miles]. Did not get apogee.

00 09 54.5

P

Mark. One picture of the booster. Going to transmit and record now., 3, 4, 5, 6, . . .10, 11, 12 pictures of the booster, traveling right down the center of the booster, right down the center of the window.

00 10 34

P

Going over the insertion checklist now. D-c volts is main. Retromanual fuse switch is off. Retromanual is off. All instruments are. All batteries okay. The a-c power is good. The, let's see, where's the booster', There's some beautiful cloud patterns down there. The booster is in front of a large cloud pattern. I seem to be, I seem to be much closer to the earth than I expected to be. The booster is approximately 2 miles away now.

00 11 40

P

I have some pictures of the booster, maybe 17 or 18, all together. Then going to the horizon, north sweeping south. There is the moon, just setting. Winding the camera at this time.

00 12 22

P

There are some rather large pieces floating around. The flight plan is now out. Gyros are going to free at 12 33, and I'm going to By-by-wire to track the booster. I will-this is not a good tracking problem. Our speeds are too close to being the same. I will put it in the center of the right window, plus. I have it right in the center-I feel that-overshot there. Getting ahead of me in pitch.

00 13 29.5

P

The high thrusters work well, close tracking should be done on- on fly-by-wire low only. To follow the booster is a tough job with the highs. Gyros are staying within limits pretty well. Elapsed time is 13 56. I have lost sight of the booster at this time. I'll pick up a retroattitude at this time for Canary radar. Large piece of-

00 14 37.5

P

Going back to gyros free, or to gyros normal

00 14 47

CC

Aurora Seven. This is Canary Cap Com. How do you read? Over.

00 14 51

P

Hello, Canary Cap Com. Aurora Seven. Reading you loud and clear. How me?

00 14 56.5

CC

Read you loud and clear also. We have radar track. Please remain in orbit attitude.

00 15 02

P

Roger. Understand. I, my control mode is fly-by-wire, gyros normal, maneuver off. I am picking up retroattitude and automatic control very shortly. Over.

00 15 18.5

CC

Roger. Will you verify that your retrodelay switch is in the normal position?

00 15 24

P

Retrodelay is normal. I say again, retrodelay is normal.

00 15 38

CC

Roger. Will you please proceed with the short report, fuel and oxygen readings.

00 15 38

P

Roger. Fuel 103-100 [percent]. Oxygen 89-100 [percent]. All the power is good. Aurora seven status is Go in all respects. Over.

00 15 53.5

CC

Roger. Say again fuel, please. Over.

00 15 56.5

CC

Please send blood pressure. Over.

00 16 07

P

Roger. Blood pressure start now.

00 16 19

P

I have, west of your station, many whirls and vortices of cloud patterns. Pictures at this time-2, 3, 4, 5. Control mode is now automatic. I have the booster directly below me. I think my attitude is not in agreement with the instruments. It's probably because of that gyro free period. Outside of a minor difference in attitude indications, everything is proceeding normally.

00 17 14

CC

Can you confirm orientation, ASCS and fly-by-wire...operating normal?

00 17 21.5

P

Roger. Wait one.

00 17 53

P

Roger. Canary, TS plus 5 is verified. Manual is satisfactory in all axes. Fly-by-wire and auto is satisfactory, all axes. Aux Damp is okay also. Over.

00 15 08.5

CC

Roger. I have copied. I have new end of orbit, end of mission and 1 Bravo times for you. Are you prepared to copy?

00 20 16.5

P

Roger, Canary. I'm going to have loss of signal before I get these. I want to get some pictures. Have Muchea or, correction, have Kano send these to me in this order: Sunset, sunrise, sunset, sunrise, break, break. Did you copy?

00 20 36

CC

-plus 41 plus 20. Did you copy? Over.

00 20 40.5
