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) .
8ee1: 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
