[4] Manufactured by Eastman Kodak, the film was initially 0.0003 inches (7.6 µm) thick, with a resolution of 170 lines per 0.04 inches (1.0 mm) of film. [28] Beginning with flight number 69, a two-capsule system was employed. ctx.submit($form, onSuccess); var o = {}; [9] Originally, Corona satellites were designed to spin along their main axis so that the satellite would remain stable. The return capsule of the Discoverer 13 mission, which launched August 10, 1960, was successfully recovered the next day. // Focus on the email input box //hide form fields and show thank-you message Fact Sheet Imagery System Information CORONA Pioneers CORONA Interactive Model The GAMBIT and HEXAGON Programs D-21 Program Innovate@NRO FOIA.

National Air and Space Museum. No orbit. This was a 750 kilogram satellite launched by a Thor-Agena rocket. Due to the failure of the booster cut-off switch, the satellite went into a highly eccentric orbit. return; Destroyed by range safety officer. Although the best resolution was only obtained in the center of the image, this could be overcome by having the camera sweep automatically ("reciprocate") back and forth across 70° of arc. No orbit. + '<\/div>' + '<\/div>' If none was found or the corona observed was within acceptable levels, the canisters were certified for use and loaded with fresh film for a launch mission. First series of American imaging spy satellites. Its bucket was successfully recovered in midair during the 65th orbit (the 13th recovery of a bucket; the ninth one in midair). setNewsletterCookie('closedSignupBar', 1); Later missions would be able to resolve objects just 5 feet (1.5 m) in diameter. Low-resolution mapping missions; single frame camera. NRO … [42] This was the first time that any object had been recovered successfully from orbit. Subsequently, a further declassification has released thousands more images from the KH-7 program, a “spotter” satellite that took high resolution images of places of interest identified from CORONA … // Submit the form Two later versions of the Samos program, such as the E-5 and the E-6, used the bucket-return approach, but neither of these programs carried out any successful missions. top: 'auto', //show automatically after delay By Eric Roston. return ""; [18] Image quality is variable and displays areas of soft focus and image smear. + '' + '<\/div>' Vehicle attitude became erratic on the global economy can be previewed and ordered through the EarthExplorer!
