The launch of Discoverer 37

Discoverer 37, also known as Corona 9030, was an American optical reconnaissance satellite which was lost in a launch failure in 1962. It was the last KH-3 Corona''' satellite, which was based on an Agena-B rocket.[1]

The launch of Discoverer 37 occurred at 21:41 UTC on 13 January 1962. A Thor DM-21 Agena-B rocket was used, flying from Launch Complex 75-3-4 at the Vandenberg Air Force Base;[2] however, it failed to achieve orbit.[3]

Discoverer 37 was intended to be operated in a low Earth orbit. It had a mass of 1,150 kilograms (2,540 lb),[4] and was equipped with a panoramic camera with a focal length of 61 centimetres (24 in), which had a maximum resolution of 7.6 metres (25 ft).[5] Images were to have been recorded onto 70-millimeter (2.8 in) film, and returned in a Satellite Recovery Vehicle at the end of the mission. The Satellite Recovery Vehicle which was to have been used by Discoverer 37 was SRV-571.[4]
