Thor Agena B with Discoverer 29 (Aug. 30, 1961)

The launch of Discoverer 29

Discoverer 29, also known as Corona 9023, was an American optical reconnaissance satellite which was launched in 1961. It was the first KH-3 Corona''' satellite, which was based on an Agena-B rocket.[1]

The launch of Discoverer 29 occurred at 20:00 UTC on 30 August 1961. A Thor DM-21 Agena-B rocket was used, flying from Launch Complex 75-3-4 at the Vandenberg Air Force Base.[2] Upon successfully reaching orbit, it was assigned the Harvard designation 1961 Psi 1.

Discoverer 29 was operated in a low Earth orbit, with a perigee of 138 kilometres (Template:Convert/round mi), an apogee of 511 kilometres (Template:Convert/round mi), 82 degrees of inclination, and a period of 91 minutes.[3] The satellite had a mass of 1,150 kilograms (Template:Convert/round lb),[4] and was equipped with a panoramic camera with a focal length of 61 centimetres (Template:Convert/round in), which had a maximum resolution of 7.6 metres (Template:Convert/round ft).[5] Images were recorded onto 70-millimeter (Template:Convert/LoffAonSon) film, and returned in a Satellite Recovery Vehicle two days after launch, however all of the images returned were found to be out of focus.[4] The Satellite Recovery Vehicle used by Discoverer 29 was SRV-554.[2] Once its images had been returned, Discoverer 29 remained in orbit until it decayed on 9 September 1961.[3]
