Discoverer 28, also known as Corona 9021, was an American optical reconnaissance satellite which was lost in a launch failure in 1961. It was the seventh of ten Corona KH-2 satellites, based on the Agena-B.[1]

The launch of Discoverer 28 occurred at 00:01 UTC on 4 August 1961. A Thor DM-21 Agena-B rocket was used, flying from Launch Complex 75-1-1 at the Vandenberg Air Force Base.[2] It failed to achieve orbit after the Agena's guidance and control system malfunctioned.[3][4]

Discoverer 28 was to have operated in a low Earth orbit. The satellite had a mass of Шаблон:Convert,[5] and was equipped with a panoramic camera with a focal length of Шаблон:Convert, which had a maximum resolution of Шаблон:Convert.[4] Images were to have been recorded onto Шаблон:Convert film, and returned in a Satellite Recovery Vehicle.
