Eventually, a team of scientists and engineers from the project and from academia (among them Luis Alvarez, Sidney Beldner, Malvin Ruderman, and Sidney Drell) determined that electrostatic discharges (called corona discharges) caused by some of the components of the cameras were exposing the film. Satellite failed to separate from booster. if (window.jQuery) { Spanning nearly the entire globe, the photographs were declassified in the mid-1990s. Capsule recovered from water on orbit 32.

Corona imagery has also been used by Romanian forest engineers studying landscape history, biologists tracing the destruction of Chinese mangroves, geoscientists forecasting water levels in a Nepalese lake, scientists measuring rock glacier movements in central Asia, and biogeographers tracking marmots’ nesting habits amid destructive agriculture practice in Kazakhstan. Discrepancies in planned and actual coverage due to telemetry problems during the first 6 revolutions. } Cameras operated successfully.

Recovery of Discoverer 14 return capsule (typical for the Corona series). 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. [22] Beginning in 1967, two horizon cameras were used. The classified military satellite systems code-named CORONA, ARGON, and LANYARD acquired photographic images from space and returned the film to Earth for processing and analysis.

Please try again later.' Destroyed shortly after launch. [21] Although improvements were made to reduce the corona, the final solution was to load the film canisters with a full load of film, feed the unexposed film through the camera onto the take-up reel with no exposure. Failure of velocity altitude programmer produced poor imagery after revolution 5. [47] The further review by photo experts of the "obsolete broad-area film-return systems other than Corona" mandated by President Clinton's order led to the declassification in 2002 of the photos from the KH-7 and the KH-9 low-resolution cameras. The Corona satellites were used for photographic surveillance of the Soviet Union (USSR), the People's Republic of China, and other areas beginning in June 1959 and ending in May 1972. The images … [14] The lens on the camera was constantly rotating, to counteract the blurring effect of the satellite moving over the planet.[9].
