DISCLOSURE / FILE

Stafford and Cernan Deny ATDA Sparkles

NASA-UAP-D022, Gemini 9 Debriefing, 1966

NASA-UAP-D022 is a June 16, 1966 NASA scientific debriefing transcript in which Gemini IX-A astronauts Thomas Stafford and Eugene Cernan discussed meteors, zodiacal-light photography, airglow, window effects, dumped material, and whether they saw flashing lights or sparkles near the ATDA target vehicle.

Brief

The transcript records a NASA debriefing of Stafford and Cernan after the June 3-6, 1966 Gemini IX-A mission. The pages tied to unusual observations describe a bright whitish-green meteor, luminous particles at sunrise, possible window or external contamination, lightning, airglow, and a direct question about sparkles coming off the ATDA. Stafford said the crew never saw flashing lights from the ATDA and answered no when asked about sparkles, while a later note records strong results from zodiacal-light and airglow photography.

Key points

The debriefing was held June 16, 1966 in MSC Building 4, Room 277, with about 40 attendants and discussion of Gemini IX experiments including micrometeorite collection, zodiacal-light photography, and general scientific observations.p.2
Stafford reported a bright meteor seen while looking down at Earth, and the next page describes it as whitish-green and moving left to right.p.3
The transcript connects some observed material around the spacecraft to known dumps of water and urine, described as a mass with barely an ounce of material.p.3
During the S-1 zodiacal-light section, Cernan said the crew turned out all lights except three red lights inside the spacecraft before photography.p.4
The astronauts took 18 zodiacal-light pictures, with 17 described as good.p.4
Cernan described seeing a world of stars after the lights were put out, while noting a light leak inside the capsule from the attitude-control system.p.5
The ATDA was about 20 minutes away and roughly 10 Venus diameters in apparent separation, but the transcript says the crew never saw flashing lights.p.5
When asked whether sparkles came off the ATDA, Stafford answered no.p.5
A July 6, 1966 NASA memorandum says about 40 usable airglow pictures were made and that the S-1 zodiacal-light pictures were the best yet on Tri-X film.p.12

Most interesting

The Gemini IX-A crew reported that a fuel-cell purge and urine dump produced snowballs.
The debriefing records a question about whether observed material was in space or on the spacecraft window.
The crew saw lightning everywhere after sunset.
NASA noted that Gemini IX-A imagery over Peru showed a lake not found on existing maps, prompting the Peruvian Embassy to send a military plane to investigate.
The transcript says Cernan was too fogged up during EVA to proceed with a planned set of observations.

Gemini IX Debriefing [ILLEGIBLE] 277, June 16, 1966

Attendants: 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 pictures.

S-12: Hemenway and Gene Flaherty.  Micrometecrite Collection on Gemini  Agena.
S-10: The astronauts reported they could see the collection box.  Sorry they
      could not go to it to open it.  But there it was bright and shiny.

S-12: Biological analysis
      (1) Swabs- taken both pre-flight and post-flight
           Pre-flight were dirty
           Post-flight "  sterile.
           3 locations inside the S/C
      (2) 5 organisms tested
           2 did not survive
           2- penicillium and T-1(?) survived/ bacteriophages
      The biological results are easier to get at and so the results will
      come out earlier.
      Micrometecrite collection had 18hrs. with two exposures-two openings and
      closings of the box from the panel and final recovery by EVA.
      The S/C was in drifting flight, looking in all directions, but actually
      not so much yaw as pitch to quote the astronauts.

Some artifacts were present -how made is beyond our understanding.
"You've done for us a really fine job."
Astronauts-
     No problem in recovering S-12.  Had to pull it off, but it didn't stick.
          Didn't use lanyard (meaning!) We heard the squib when it closed.
          We were quiet one day and didn't fire the thrusters.
     Zeitler has the times of opening and closing the control box which were
          called down from the S/C

Hemenway to astronauts:  Can you tell me about like any discarding of material?

Astronauts- At end of first day we had used 80% of fuel(500#).
     We [ILLEGIBLE] purged the fuel cells and had a urine dump which gave
          snowballs

     - During EVA I noticed that the S/C was clean
       Stafford says estimate was that for 30 mins it was absolutely clean.
                                                        in?

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 ounce--


Hemenway- To assume that all the holes are real- we count 9 holes in
     5 sq. cm. in 7x 10 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 proably
     were not very high.


Dubin- (this) is a portion of sample we've looked at, the scanning prodess is
     glow..
     would like to investigate the gold visor--gold is soft..
     Luminous particles... at sunrise on blunt end (S/C) they always show at
     sunrise.

Roach- Could they cause what S-12 sees?

Hemenway- Stains show when we open the collection box.
          Much more was collected (guest investigator portions) and we are
          worried about contamination between these separate portions.

Stafford- At one time there was an N2O4 yellow drop right on my window..

Go to p.3.

Gemini 9 Debrie[fing] - p.# 3

· Hemenway- About S-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 toomuch!
     During EVA - drifting so much..
     During EVA just maintaining position is our most difficult task...
          restraining the feet.

Stafford- Gene produced some much torque when he stepped out of the S/C,
     that he rolled me 150 degrees, etc...
     I don't think we could do it(the expt) outside..

Ciernan- We turned out all the lights except 3 red lights inside the S/C.

     I put the camera again the(?) and slid it against the frame so
     I could hold it hard against the frame and then Tom went for the
     (proper) past of the horizon..
     The pitch was difficult- to sight the horizon over the (nose)
     and vertically to get the Milky Way on the window.

[X] 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 volume(mass) to barely an ounce.

We took 18 pix; Moon on the last one; then sunrise..

17 were good..

The first picture was taken toward the north.

[X] Ney- Would you like a sight?  Would give finite--
     15 secs, 30 secs in center
     (Your) worst holds only represent 1 or 2 degrees...are the null rates for
     orbital or inertial?

     How well did you think you held???  and then I'll show you the pictures..

Ciernan- Didn't need a handle on the camera- it's on right and down.  I feel camera
     was held real well.  Problem was rates were even harder than in S-11..

Ciernan- It was still difficult to line up the camera with the black horizon,
     etc.  I concentrated on looking in the right direction.  (0.8 deg.
     in each direction.)

     Problem- the windvo is at an odd angle

Page 5vision OCR

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..
* Lights were put in the room to see the pictures and it is difficult to read the
     They saw the zodiacal light visually          notes

Day after full moon.
Lightning?

Magellanic clouds? (I think the ans. 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 light in the sunrise photos (Venus)...like Gordo Cooper's
     description of visual view.

Roach- Could you hold on a bright star?

Stafford- If could use a reticle and a boresight, could really be on the needle.

Ney- Should we never think of a 2 minute exposure?
Ciernan- 30 secs seems a long time.

Ney- Voice tape?  Are time hacks on each? Ans/ NO.

Zeitler- I didn't see anything on that.

Ciernan: Maintaining position was a major problem.

Ney: How to do it outside?

Stafford: Mount camera clamped to forward hatch.

(Did you see the ATDA?)

THE ATDA was 20 mins. away, about 10x diam. of Venus....never saw any flashing
     lights.

Roach: Did you ever see "sparkles" coming off the ATDA?

Stafford: No, none..

          Whitish-blue and then whitish-orange..(?)

Page 6vision OCR

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 more control

C:  lost..

S:  lost..

Ciernan: We took the "timer" off as it wasn't working..used time hacks..

Stafford:  It was a very difficult operation and (he) was in a terrible position..

     --Our hands were cramped and sweaty afterwards(from the effort)..

Koomen: the control was too coarse?

Ciernan: Make lever arm as short as possible on the pitch control..
          Hard to get in these positions in zero G.

Koomen: You were holding on to what you were supposed to guide..

Ciernan: No finger prints because of way things were handled..

Koomen: Was bracket on the window from orbit to orbit?

Ciernan: Yes took it off prior to EVA..
          Didn't get the last 2 pictures because the camera was stowed before S-1 and
          they...

Page 7vision OCR

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 S-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 dots were what you need, not 3 (on camera or panel or what?)

Koomen- Could you adjust brightness of points?

Ciernan- Not as fine as I'd like-- I'd like to go dinner..

Koomen- Did you use ring on shaft?

Ciernan- Yes, with my fingernail..

Koomen- Were you pressed for time?

Ciernan- As a matter of fact we had time to wait for sunrise..
     - It was slower because we were saving fuel.

Stafford- Boresight would reduce time by 25%.

Koomen- Was the estimate to take the twilight pictures ok?

Ciernan- We took what you gave, and apparently they were..

Koomen- Would it be better just to use your own judgment?

Ciernan- No, I was glad to have the times..

     - We were glad to have the time so we knew what to shoot at..

Koomen- Did you see and color in the twilight airglow

Ciernan- No, just grey or NO COLOR.
     - I would use milky to describe the appearance..

(Koomen showed slides of many of his pictures which were very good.)

Koomen- Na filter and minus Na filter show somewhat differrent levels

Lintott- What about boresighting?
Ciernan- Yes, it could bring yaw on          *********

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 during Gemini VI, and
          Sirius and Rigel.

     Lowman: 50 or 60 useful pictures of S. America; only had a few before.

     Ciernan: Could only see streams flickering through (the jungle?)
          Very dark above the rain forest.
          "Greens," no..Black tempered with green.

     Lowman: Any blues off the NW coast of S. America?

     Stafford: C[an]'t answer.

     Ciernan: Hasselblad with filter..

     Stafford: Maurer (camera)..
          Did not have the GT-10 (terrain photography) flight plan; no onboard
          data (to direct this picture taking).

          : Maurer worked well, better than the Hasselblad.  A strip over Africa
          was taken.

     Dunkelman: Use faster speed, 1/500th sec..why not try?
          Towering decks of clouds..

     MSC ques. re STRAPS

     Ciernan: I'm against straps, lanyards and tethers..
          If have to get up, you will need restraint because your feet will
          start floating...

Page 9vision OCR

8.
Ciernan: Couldn't see out my window obliquely..

Stafford: Window covers did help some (protected on launch and jettisoned in
     flight did help cleanliness of windows).

Roach: You did see the zodiacal light several times?  How close to the Sun?

Ciernan: No chance to look for these phenomena as such because we had to sleep
     or look for ATDA.

                              Underwood
Color PICTURES: Some good limb shots..  ([ILLEGIBLE])

Dubin:  Moon?

Ney:  Could you occult the moon behind the ATDA?

Roach: Could wash out stars with the moon..

Underwood:  ATDA and moon in some pictures..

Ciernan: I had a plan to observe a number of things, but when the time came
     (during EVA) I was so fogged up that I couldn't proceed (with the plan.)

Roach: It is important to find out whether the problem is with stuff "in space"
     or whether it is on the window..

Stafford: It's my impression that it's something outside..

Ney: Was sun ever occulted by the ATDA?

Stafford: WE didn't stay with it too long..

Ciernan: WE closed hatch while outside (during EVA).

Ney: Did you see stars as well then (Sun visible to Ciernan) as at night?

Stafford: As black then as ..

Ney:  Earthlight might cause the problem..
     We are trying to distinguish between
     1. Daytime with earthlight

7 /6/66 Memorandum to the File From: J. R. Gill Subject : Experiments Debfiefing of Gemini IX held in Bldg . 4, MSC at 8:30 A.M . June 16,1966 . Gemini IX ' s performance on the 0SSA experiments was impressive . The guiding performed for S011 and S001 was the best that has yet been done on a manned spacecraft . In all 40 usu.able pictures of the airglow were made with the 2- filter (split field) arrangement attached to the wide angle Maurer lens ( NRL' s experiment) . 8 ee1 : was done inside the capsule since it was not possible to attempt it during the EVA . THey got pictures of the zodiacal light and the Milky Way and the guiding was good even for the 30 sec sweeps . On Tri-X these are the best pictures yet of the zodiacal light surpassing the results achieved on Gemini V. S011; About 40 usable pictures of the airglow were obtained. THese contain some of the same star fields pictured in S00l. Guiding was very good even though Cernan had to do the experiment from a very awkward position . S012 : Hemenway showed several pictures which were enlargements (up to 35 , 000 exposed times) . Only a small portion aJf the/ surface has been a.na.lyzed, but on this portio portion 9 impacts are recorded . Hemenway is investigating possible "contamination between experiments before sending the individual sections to guest investigators . On the biological experiments where the results come ou:b faster (a) 3 swabs taken inside the s/c re- flight were dirty ; post-flight these same areas were sterile . (b ) the T-4 bacteriophages and t he penicilliumspeciroens

2 . survived the spaceflight; two other speciment. The 30-day report on this experiment will contain more results, but the full micrometoerite analysis will take some time. S-5 and S-6: These experiments were not officially carried, but nonetheless it was done as "operational procedure." In all some 300 color pictures were taken with the Hasselblad and Maurer cameras both of which were carried (for the first time. The Maurer is eventually planned to replace the Hasselblad, but this has been slow in evolution.) A strip was taken over Peru where the weather happened to excellent. Features show up in these pictures which do not appear on any existing map; for example, a glacial lake in the Ange~ which do not appear on any existing maps. The Peruvian Embassy has been informed of this lake which may portend an avalanche hazard for villagesilocated below, The Peruvians have sent a military p-l,ane into the area to investigate . THis indicates the possible current use of such pictorial information . THe AMU exercise was unsuccessful. It proved to be too Im.lCh "work" under the present arrangements. It takes two hands just to control the body peeitionang . Hand-held photography during EVA for experiments looks "out of the question" at pres ent. J oc elyn R. Gill

U . S . NAVAL RESEARCH L AB O RATORY WASH INGTON , D. C. 20390 Code 7020 21 June 1966 Dr . Homer E. Newell Associate Administrator Space Science and Applications National Aeronautics and Space Ad.ministration Washington, D. c. 20546 Dear Homer : First, in behalf of the NRL- GSFC collaborators in Gemini Experiment S- 9, I want to express deep gratification at t he strong int erest in and concern for the success of our experiment shown by you and by Dr . George Mueller . The substantial help that both of you and your associates in NASA have given us is much appreciated. The proposal to include two high- altitude orbits in the flight plan for Gemini mission XI has been carefully examined by physicists at MSC Houston, as well as by our joint NRL- Goddard group . At a meeting in my office yester day with officials from NASA Headquarters and from MSC , Houston, we agreed that the S- 9 experiment would not be hurt if the flight plan included t wo elliptic orbits bavine an altitude of 75 0 nautical miles at apogee (approxi mately over Australia ) during the 26th and 27th orbits . Our emulsion stack apparatus would be retrieved from the retroadapter section during the first EVA , and stored inside the Gemini capsule in a manner suggested by Messrs . Joseph Lill and Peter Higgins of MSC, with an orientation that would m inimize the effect s of background radiation incident on the window face of the package . In short, we believe that the proposed high- altitude orbits are compatible with the S- 9 experiment . May I digress t o say that we in the NRL group are looking forward to favorable consideration by the Manned Space Flight Experiments Board of our recent Apollo proposals for cosmic- ray studies outside the magnetosphere , and for observations of cosmic y- rays in earth- orbiting Apollo vehicles . With warm regards , Sincerely, J.><urice 1:! 3hief Scientist Laboratory for Cosmic Ray Physics Principal Investigator, s- 9) P . S. A list of those attending the meeti ng in my office yesterday is attached.

LABSTRACTS No. 23 U. S. NAVAL RESEARCH LABORATORY, WASHINGTON , D.C. June 10, 1966 USRL Joins RL Effective July 1 the Navy Underwater Sound Ref erence Laboratory (USRL) in Or land o, Florida, will be disestablished and become a di v i s i o n of NRL. It will be designated as the Underwater Sound Reference Division (USRD). As a division of NRL, USRD, in its program of standards and instrumen tation development for imderwater sound measure ment, will be re-enforced by the spec i a 1i zed capabilities of related elements of the NRL research staff. The f i n an c i a 1, management, and support services requirements will be backed up by the service organizations of NRL. The new division will continue under the imme diate supervision of the Chief Scientist, Mr. O. M. Ows ley. Mr. Owsley will report directly to Capt T. B. Owen, Director of NRL, for the management of the operations and the effective prosecution of the program. He will be guided as appropriate and in their resp ective areas, by NRL's Director of Research, Director of Support S e r vi c e s, and Comptroller. continued - page 2 NRL Signs Labor Contract for Guard Unit The U.S. Naval Research Laboratory and Colum bia Lodge No. 174 of the International Association of Machinists and Aerospace Workers have nego tiated a comprehensive agreement covering all non supervisory security guards in the Laboratory's Security and Administrative Services Division. Following a grant of exclusive recognition to the Union on January 19, 1966, negotiations began on March 31, 1966, and were concluded on May 26. The Laboratory's negotiating team was beaded by Capt J. C. Matheson, Director of Support Services, and inc luded LCdr J . H. DalPian, Se c u r i t y and Administrative Ser vices Officer, and Mr. T. F. Garnett, Jr., of the Personnel Division . The chief negotiator for the Union was Mr. R. W. Fauntleroy, Business Representative of Columbia Lodge No . 174. Mr. Fauntleroy was assisted by Mr. R. E. Bunner and Mr. H. B. Brooks, both members of the Laboratory's guard force. The completed agreement was signed at 3:00 p. m. on Wednesday, June 1, in the Office of the Director of Support Services. The effective date of the agreement is June 2, 1966. It is anticipated that the agreement will remain in effect for one year with the possibility of its subsequent extension continued - page 2 Chair of Cosmic Ray Physics Established Effective May 11 the Laboratory established a Chair of Cosmic Ray Physics for Dr. Maurice M. Shapiro, who recently r esigne d from the Superin tendency of the Nucleonics Division after 12 years in the latter position. The post of Chair of Science was c r eat e d by the Laboratory to confer special recognition on the incumbent as a distinguished scientist of exceptional accomplishment. The staf.f of the former Cosmic Ray Branch, which Dr. Shapiro organized and led since 1949, will constitute the L ab oratory for Cosmic Ray Physics , with Dr. Shapiro as Chief Scientist. The Laboratory for Cosmic Ray Physics is en gaged in studies of the primary cosmic radiation its composition, energy spectra, and other proper ties. This group of physicists composing the Lab oratory has become especially well-known for its significant contributions to our knowledge of the helium component and the heavier primary nuclei of the cosmic radiation, as well as for its earlier work on elementary particles. Dr. Shapiro is also Principal Investigator for the Gemini Cosmic Ray Experiment S-9, a collaborative enterprise of the Laboratory and the Goddard Space Flight Center. The emulsion stack designed for this experiment was lost on the ill-fated Gemini VIIl but, the ex periment is re-scheduled to be flown on Gemini Flight XI. Savings Bond Campaign Extended The Federal Savings Bonds Chairman, Postmas ter General Lawrence F. O'Brien, has announced that he is extending the 25th Anniversary Savings Bonds Campaign for F ederal Employees through continued - page 2

2 NRL LABSTRACTS USRL - continued As a part of NRL, the new division's work will remain essentially unchanged. Its mission, now incorporated into the mission of NRL, is to conduct research and development furthering the science of underwater sound measurement, to provide to other naval activities the resulting scientific knowledge, new or improved t e c h n i q u e s , and standardized instrumentation, and to provide facilities and ser vices for the accurate calibration of standard in strumentation and the wibiased determination of performance characteristics of development, pro totype, or operational underwater sound devices used by the Naval Establishment. Several of NRL's key personnel, including Capt T. B. Owen, the Director, and Dr. C. E. Cleeton, the Associate Director of Research for Electronics, have visited tbe facility to arrange for the transition. The 10. 5 acres of LabOratory ground occupied by USRD are located alongside Lake Gem Mary, one mile south of the city limits of Orlando. It has a personnel complement of 98 people: 97 civilian and 1 military. The Laboratory extends a hearty "Welcome AbOard" to its new staff members and looks forward to publication of articles about the new division. CONTRACT SIGNED - continued for one additional year. Significant provisions con cerning promotion, s c he du ling of annual leave, hours of work, and a grievance procedure with pro visions for advisory arbitration, are among the seventeen articles included in the agreement. This is the second agreement covering Labora tory employees negotiated within the framework of the F e d e r al Employee-Management Cooperation Program as set forth in Executive Order 10988. The first agreement, covering all wigraded non supervisory employees at the Washington complex of NRL, became effective on December 21, 1964. Re-negotiation of the latter agreement is expected to begin in the early fall of this year. SAVINGS BOND CAMPAIGN - continued June. He said that the additional month is needed to assure that every civilian and military employee of the Federal Government throughout the world is given an opportunity to sign up for regular pur chases of Savings Bonds through the Payroll Savings Plan. The Postmaster General expressed confidence that the campaign goal of 75 percent participation by Federal employees will be achieved. So far in NRL' s Savi.ngs Bond Campaign 94 people have i n c r ea s e d their Bond allotments, and 157 people have signed up for Bond deductions, making a total of 1,628 Bond savers. The Laboratory's percentage of participation is now over 50. This extra month affords you the ex c e 11 en t opportunity of signing up for Bonds. Why not jump on the "Bond Wagon" today? Elected Fellow of the American Academy of Arts and Sciences Dr. Richard Tousey, Head of the Rocket Spec troscopy Br an c h, Atmosphere and Astrophysics Division, was elected a Fellow of the American Academy of Arts and Sciences at the Academy's 186th Annual Meeting held May 11 in Boston, Mass. The American Academy of Arts and Sciences, was founded in Boston in 1780 by John Adams and other revolutionary leaders of the Massachusetts Bay Colony. Among the prominent members of the past have been George Washington, Oliver Wendell Holmes, Horace Mann, Sir Winston Churchill, and John F. Kennedy. Dr. Tousey, who is a member of over a dozen major scientific and professional societies, is now a Fellow in four of them. Previously he had been elected Fellow by the American Physical Society, the Optical Society of America, and the American Geophysical Union. Moreover, Dr. Tousey's work here has earned him numerous special honors and awards, including the Navy Award for Distinguished Achievement in Science (1963), the Henry Draper Medal of the National Academy of Sciences (1963), and the Frederic Ives Medal of the Optical Society of America (1960) .

OPTIONAL fOI.M NO, I 0 M.AY 1'62 fDITIOH GSA PPMI: U.I Cfl) IOl-11.6 U Manned Flight Experiments Office SM/Manned Flight Experiments Office DATE: J une 6, 1966 !TED STATES GOVERNMEN Memorandum SM/Director, TO FROM Sci entific Experiments carried out oh Gemini IX SUBJECT: ~ The Gemini IX mission carried the following OSSA experiments : S -10 Agena Micrometeorite Collection S -11 Airglow Horizon Photography S - 12 Gemini Micrometeorite Collection In spi te of a slight flurry last Friday night to t brow in additional experiments as a possible backup in the event of failure of the .ATDA, no new experiments were introduced . Thi s was a consequence of the decis i on to i ntroduce no additional film packs which could have acconnnodated some moreexperimental activity. (Ref . TWX to Dr . John Clark re S- 28 support for Gemini IX, 5/27/66 and TWX to 4 experimenters and their directors re S- 5, S - 6, S-28 and S-29, 5/31/66) . Nonetheless , i t is anticipated that some photographs will have been taken for S-5 and S -6 (Synoptic Photography) on the operational film carri ed - even though this experiment was not scheduled for Gemini IX . As of Sunday, June 5th at ll : 30 e . d . t . telephone contact with Norman Foster ' s office indicated the following on experiments . {Talked with Ed Zeitler, MSC both Saturday and Sunday . He i s the editor on the experiments status report) . The efforts to di slodge the shroud from the .ATDA, (called by Tom Stafford as "an angry alligator, ") were in vain so docking with the ATDA was scrubbed from the mission . At this point there was some concern over the fuel supply and a thought that i t might not be possible to carry out all the experiments . The status of sci entific experimental activity is given below . 1 . S-10, Agena Micrometeorite Collecti on, Dr . C. Hemenway, Dudley Observatory The S- 10 was carried on the .ATDA, but it was imposs i ble to get near i t or to retrieve i t . The S- 10 was also carri ed on the Agena and there was no activity with it ei ther . The S -10 i s still on the .ATDA and conceivably could be retrieved on a later mi ss i on . l Buy U.S. Savings Bonds Regularly on the Payroll Savings Plan .$010-101

2 2 . S-11, Airglow Horizon Photograpby, M. Koomen, Naval Research Laboratory The astronauts made 3 night passes on this experiment and reported bno problemshso it is assumed that the experiment went off as planned . They may be able to devote 1 more night pass to it during the mission . They are still planning the 2 -1/2 hour EVA . At the start of the experiments they had 50 lbs . of fuel left and at the end, so it is reported, they still had 50 lbs ! ! (GET 27 hrs , 29 hrs , 31 hrs for S -ll). 3. S -12, Gemini Micrometeorite Collection, Dr . C. Hemenway, Dudley Observatory The collection box was activated and had five hrs~ exposure before closing it so jets could be freely used . The decision was made to reactivate it during the astronauts 10 hr . sleep period . It was closed again and retrieved by Cernan during his space walk. So S -12 collection box is being returned in the Gemini IX capsule . (The experimenter was asked whether it would be safe to try a second exposure and asked whether the astronauts could recall whether the closing cycle on the box had taken about 30 secs . They apparently could not hear it and so could not make this determination . ) * (GET 12 to 17 hrs . ) S-5 and S- 6, Synoptic PhotograJ?hl, Dr . Paul Lowman and K. Nagler There is no word on how many pictures have been taken . The newspapers have made reference to a picture of Baja California, and since there was a good deal of operational film aboard, it is expected that there may be quite a few . Cernan during EVA was asked whether he had the Hasselblad camera outside and the reply was 11 yes , 11 In talking with Dr . Lowman I learned that this is probably the wide -angle (90 deg . ) Hasselblad and may very well produce some spectacular pictures . From the standpoint of our experiments this seems to be a good mission. We should have results from S -12 and S-ll as well as S - 5 and S - 6 . Many more pictures for the successive volumes of the Earth Atlas . ~a.~ 'R. ~ Jocelyn R. Gill Manned Flight Experiments Office

A new bracket, satisfactory to both MSC and the experimenter, has
been constructed at the Naval Research Laboratory. This new
bracket was seen at the meeting in St. Louis, is incorporated in
the training unit, and MSC is well satisfied with it.

There is just one night pass for accomplishment on Gemini IX in
view of extra operational considerations of S-11. This will
make it possible to get 14 exposures and a sunrise period. This
is not what Koomen, principal investigator, requested. He asked
for four (4) night passes originally. Apparently, navigational
equipment will have to usurp this time on IX. S-11 is scheduled
for reflight on Gemini XI and XII.

S-10, S-12:

Both units have been checked out and fit-checked with the S/C.
S-12 is opened from inside the cabin by an upper right-hand
toggle switch designed to prevent inadvertent activation. Both
pieces of equipment will be fit-checked at the Cape and then
returned to the principal investigator at Dudley Observatory for
flight loading. There is "clean room" space for Dr. Hemenway
at the Cape also.

On Gemini IX the first activity will be to activate the S-12
which is done from inside the cabin. The second activity will be
to open the S-10 micrometeorite box on the Agena. The S-10 box
is fastened to the Agena by a velcro patch. (Just which Agena
will be approached is unknown at this time; S-10 was attached to
the Agena belonging to Gemini VIII; if all goes as planned there
will also be one on the Agena belonging to Gemini IX. The SEDR
M460 is scheduled for May 2nd and Wayne Eaton from MSC will be
there. After that the collection boxes will be returned to
Dudley for loading for flight.

According to the present plan the S-12 collection box will be
retrieved first during the EVA planned for the first day of the
mission.

In summary, there are some eight (8) hours of experiments
(scientific experiments are only part of the total complement)
scheduled for Gemini IX and there are only 4-1/2 hours in toto
available for experiments according to O. Smistad, Experiments
Office, MSC.

The final flight plan should be ready on the 18th and I have
requested a copy.

Gill SUBJECT : Status of Scientific (OSSA) Experiments on Gemini IX The following scientific experiments are scheduled for Gemini IX : S -l , Zodiacal Light Photography; S-10, Micrometeorite Collection on Agena; S -11, Airglow Horizon Pbbtography; S -12, Micrometeorite Collection on Gemini , related to S- 10; and Dim Light Photography being presented to SSSC as S- 28 on Friday, March 4, 1966 . (L . Dunkelman, GSFC) . S -l : Zodiacal Light Photography, E . Ney, Univ . of Minnesota . Astronaut briefing, Ney reports that one briefing has been held in Houston and another will be scheduled for the Planetarium . Elliott See, Charles Bassett and James Lovell were present for the first briefing: Tom Stafford was not . Under the circumstances , it is likely that the briefing will have to be repeated , Equipment, The camera equipment is now at the Cape . Documentation has presented some problems , mainly the insistence on a new serial number for the camera since it now has a handle on it . The handle is mounted with boles on the camera . Tri -X film will be used with and without the window. With hatch open and using the spacecraft as an occulting disk, the astronaut will place himself in the shadow of the s/c and see how far out he can trace the extens ion of the solar corona . He will also take 4 pictures of the airglow and a picture of the Milky Way . The principal investigator commented that he was very pleas ed with the enthusiastic reception from See and Bassett for the equipment and experiment . They have been the most interested in this experiment of all the astronauts who have been associated with it . Since Tom Stafford bas been very cooperative in the experimental program, I personally have confidence that he will pick up where See and Bassett have left off, and that the experiment can go off as planned . S- 10 : Micrometeorite Collection on Agena . It employs the same bracket as S - 12 . This modus operandi has cost more than a new design and has given much trouble . GSI ( government service inspection ) has been a problem since i t was not written into the contract . The problem is with the fairing with the handle in the open position . Lubrication bas also been a problem since the contractor has applied it in 11 glops 11 instead of following instructions . The experiment is all ready, l so far as equipment is concerned .

.. 2 S -11 : Airglow Horizon Photography, M. Koomen, NRL . No difficulties in the schedule are anticipated. This is the first flight of this experiment and the flight hardware is on schedule . The equipment has passed environmental testing . The experiment is mounted on a movable bracket and is 11 pointed 11 by the astronaut . The first briefing of the astronauts (See and Bassett) has been held and another is to be held later in the Morehead Planetarium. The astronauts seemed "reasonably happy" with the experiment according to the principal investigator . S- 12 : Micrometeorite Collection on Gemini S/C : On schedule . No problems reported by the principal investigator . This is the first flight of this experiment , having be en canceled out on GT - 6 . S -28 : Dim Light Pbotograpl¾ L. Dunkelman : This experiment was first carried on Gemini VII and VI -A as "operational procedure . " Af'ter processing by SSSC and M3FEB this month, it is hoped that it will assume full experiment status . It uses cameras already assigned to the s/c and sensitive black and white film, already qualified . Some further briefing will be required, probably at the Planetarium and possibly can be accomplished at the same time as S- l ' s Planetarium briefing . Jocelyn R. Gill
