SAMOS To The Moon: The Clandestine Transfer of Reconnaissance Technology Between Federal Agencies, NRO

"Having acquired, launched, and then terminated work on a near real time imaging satellite, however, NRO officials at that time agreed to consign the SAMOS imaging system to the National Aeronautics and Space Administration (NASA) for use in its deep space exploration program. The surreptitious transfer of this technology, a fact just recently declassified, has remained unknown to many in the NRO and NASA because of the compartmented security measures then in place. It occurred in the following manner.

When in the summer of 1963 NASA requested proposals for a five flight Lunar Orbiter imaging satellite, the Eastman Kodak Company asked for and received permission from the NRO to join The Boeing Airplane Company and bid on the program. In the effort to meet NASA requirements, Eastman would modify its E-1 camera with an 80mm focal length Schneider-Xenotar lens and an off-the-shelf 24-inch telephoto lens procured from Pacific Optical. The two lenses would be bore sighted at the surface of the moon for a planned orbit of about 30 miles altitude. Light would pass through each lens to the film, but the simultaneous images were interspersed with other exposures, and not placed side by side. The camera employed the existing velocity over height sensor to regulate the speed of the focal plane shutter on the 24 inch lens and the between the lens shutter on the 80mm lens, which compensated for image motion. The Boeing Airplane Company, in turn, designed a solar-powered spacecraft stabilized in attitude on three axes that mounted other off-the-shelf hardware, and integrated it with the modified E-1 SAMOS payload."
