Gemini IX Debriefing - 17 May Aug 4 to 27, June 10, 1966

Attendee: about 40 off and on

Experiments:

S-5: (from Mr. Underwood while waiting for the session to begin.)
300 or more pictures were obtained on Gemini 9.
Peru was almost completely covered because it was CLEAR. A new lake (?) was seen on one picture which did not appear on any existing map. Peruvian Embassy was called and they sent a military plane to investigate this lake which could be a possible hazard to villages below by producing an avalanche.
Wm. Fisher, USGS, has put out a small technical paper on the GT-4 pic…

p.2

We saw a very bright meteor—way, way out (going) from left to right, whitish-green in color.

Material was dumped between exposures—mass of water and urine—we know the mass to barely and once—

Hemenway—To assume that all the holes are real—we count 9 holes in 5 sq. cm. in 7x10^4 secs with no corrections..this gives a point on the curve (see file) in the middle of many other results. Serious difference with Pegasus.

Stafford—Is the pressure suit we have adequate?

Hemenway—the velocities range from 0 to 70 km/sec; those recorded hits probably were not very high.

Dubin—(this) is a portio…

Gemini 9 Debrief - p. 3

- Hemedway - About 8-10, we feel it is very important to do this because of the length of exposure. Agena 8 would really be worthwhile to get at -

***

S-1 Zodiacal Light, Ney and Huch and John Lintott (tech. monitor)
Astronauts to Ney - We have a message - we did the expt inside...
Ney to astronauts - How did you hold (guide) it so well?

Ciernan - We felt there would be a problem in holding 30 secs. in EVA.
I had practiced leaning on a car and 30 secs. was too much!
During EVA - drifting so much...
During EVA just maintaining position is our most difficult task... r…

4.

Ciernan- I cleaned my window-
mine had clear area in center but ridge all around-

Stafford- I couldn't even see ...

Ciernan- A world of stars when put out all the lights--
There is alight leak inside the capsure from the attitude control..
They saw the zodiacal light visually

Day after full moon
Lightning?

Magellanic clouds! (I think the one was no...)

Stafford- When the sun goes down, you see the lightning everywhere.

Ciernan- the top edge of the airglow is sharper (than the lower edge)

Pictures #9,12 were shown.

Camera was turned off between each exposure

Twilight and zodiacal l…

5.

John Lintott: a boresight would cut down the field of view..

Ney: the velcro was a night light trap..
and he ended his remarks with "It was a great job!"

Ciernan: We'd like some pictures..

Ney: We'll get you some..

***

S-11: Martin Koomen, NRL

Koomen: "After hearing the voice tape, I wasn't sure whether to come without my
hard hat!"

Ciernan: We haven't heard them yet..
How good were the rates?

Koomen: I thought they were very good.

Ciernan: the points about boresighting would be the same as for S-1.

Stafford: The platform was up all the time.

Ciernan: the sight would give you mo…

6.

Koomen- (on some pictures) the airglow is sometimes sharper than other times. There are 45 good pictures; the thruster frame is black.

Ciernan- Does the bright moon help the airglow?

Koomen- We don't think the moon affects the airglow at all.
- There is evidence of differences in intensity and altitude using (comparing) the two filters.

Stafford- Dr. Ney's experiment (is) learning curve for 8-11.
- lightning flashes

Koomen- Last 4 pictures/ 2 extra sets of exposures, 5 and 10 secs. with filters

Stafford- Decision not to go
We had 6 (numbers) of frame (panel?) left

Ciernan- Just 2 dot…

Discussion on SOll was folloed by a film showing (Quick Look at Gemini IX). 15 mins.

GENERAL SCIENTIFIC OBSERVATIONS

11:45 A.M.
Ney: Any stars in the daytime?
: No

Stafford: In twilight as we crossed the sun line, (saw) Antares.

Ciernan: Sunrise on the adapter and on the nose are quite different for the two of us (two different windows, two different views).
: He could see stars while I was in daylight.

Stafford: (Schirra saw) 3 stars in Orion's Belt…
