abstract
  • The launch of Discoverer 31 occurred at 21:00 UTC on 17 September 1961. A Thor DM-21 Agena-B rocket was used, flying from Launch Complex 75-1-1 at the Vandenberg Air Force Base. Upon successfully reaching orbit, it was assigned the Harvard designation 1961 Alpha Beta 1. Discoverer 31 was operated in a low Earth orbit, with a perigee of kilometre (mi), an apogee of kilometre (mi), 82.7 degrees of inclination, and a period of 90.7 minutes. The satellite had a mass of kilogram (lb), and was equipped with a panoramic camera with a focal length of centimetre (in), which had a maximum resolution of metre (ft). Images were recorded onto -millimeter () film, and were to have been returned in a Satellite Recovery Vehicle. The Satellite Recovery Vehicle carried aboard Discoverer 31 was SRV-552. During the spacecraft's thirty-third orbit, the attitude control and power systems malfunctioned, and as a result Discoverer 31 was unable to complete its mission or return images. It decayed from orbit on 26 October 1961.
