Kodak's "Pre-Invented" Lunar Orbiter Camera; Or, the Fate of SAMOS Readout

NASA's Lunar Orbiter spacecraft used a camera system Kodak originally built for the Air Force's classified SAMOS spy satellite program. The system, which developed film in orbit and transmitted images to Earth, was 'pre-invented' when Kodak joined Boeing's 1963 bid. After SAMOS was canceled, NASA adopted the hardware for lunar mapping, enabling the first comprehensive photos of the Moon.
