Status of Gemini IX Scientific Experiments

The experiments for the Gemini IX flight are:

S-1, Zodiacal Light Photography,

S-11, Airglow Horizon Photography,

S-10, Micrometeorite Collection on the Agena, and

S-12, Micrometeorite Collection on Gemini.

Mr. Wayne Eaton reported by telcon to me on April 21, 1966 that the condition of the subject experiments is satisfactory. Details follow.

S-1:

The equipment has been checked out by MAC. The astronauts have seen it at the Cape and are satisfied with the operational plan. They have had training units for some time. Dr. Ney and the crew have had time together so the briefing seems in good shape. The plan is to take one photo of the Milky Way and four (4) of the airglow just prior to ingress on the EVA operation. This is planned to be done on the second evening of flight. It is planned to use TRI-X film. Both units are now at the Cape and the flight loading of the film will take place four (4) days prior to the flight. During my visit to Dr. Ney on April 15th at the University of Minnesota, the principal investigator indicated to me that he was pleased with the plan and the crew briefing for Gemini IX. This confirms the telephone conversation with MSC re S-1.

S-11:

A flight unit was recently "downgraded" to training unit (this is just nomenclature). The crew has worked with the training unit and has seen the flight unit. The only difference in the training unit is that it has no actual filter, since this item is perishable, but the training unit is in all other respects identical to the flight unit. The flight unit will be at the Cape on April 29th. There has been a change in the bracket to hold this experiment. The first bracket made by MAC was unacceptable to the experimenter and apparently also to MSC.
