It was a KH-3 Corona satellite, based on an Agena-B.[1] The launch of Discoverer 32 occurred at 19:22 UTC on 13 October 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 Alpha Gamma 1. Discoverer 32 was operated in a low Earth orbit, with a perigee of, an apogee of, 81.6 degrees of inclination, and a period of 90.3 minutes.[3] The satellite had a mass of,[4] and was equipped with a panoramic camera with a focal length of, which had a maximum resolution of .[5] Images were recorded onto 70mm film, and returned in a Satellite Recovery Vehicle, which was deorbited one day after launch. The Satellite Recovery Vehicle used by Discoverer 32 was SRV-555. Following the return of its images, Discoverer 32 remained in orbit until it decayed on 13 November 1961. Most of the images it produced were found to have been out of focus.[6] References |
