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 233 kilometres (145 mi), an apogee of 350 kilometres (220 mi), 81.6 degrees of inclination, and a period of 90.3 minutes.[3] The satellite 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 recorded onto 70-millimeter (2.8 in) 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.[3] Most of the images it produced were found to have been out of focus.[6]
