Initially, each satellite carried 8,000 feet (2,400 m) of film for each camera, for a total of 16,000 feet (4,900 m) of film. ); At the time of its creation, Corona also represented an impressive feat of engineering, requiring the development of film that could survive space radiation and high air pressure—not to mention be retrieved from a satellite orbited high above the atmosphere.
