Vandenberg Air Force Base.[2] Upon successfully reaching orbit, it was assigned the Harvard designation
1961 Psi 1.
Discoverer 29 was operated in 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 recorded onto 70-millimeter (2.8 in) film, and returned in a Satellite Recovery Vehicle two days after launch, but 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]
