The launch of Discoverer 17 occurred at 20:43 UTC on 12 November 1960. A Thor DM-21 Agena-B rocket was used, flying from Launch Complex 75-3-5 at the Vandenberg Air Force Base. Upon successfully reaching orbit, it was assigned the Harvard designation 1960 Omicron 1. It was the first KH-2 satellite to successfully reach orbit.

  • The launch of Discoverer 17 occurred at 20:43 UTC on 12 November 1960. A Thor DM-21 Agena-B rocket was used, flying from Launch Complex 75-3-5 at the Vandenberg Air Force Base. Upon successfully reaching orbit, it was assigned the Harvard designation 1960 Omicron 1. It was the first KH-2 satellite to successfully reach orbit. Discoverer 17 was operated in a low Earth orbit, with a perigee of kilometre (mi), an apogee of kilometre (mi), 81.8 degrees of inclination, and a period of 95.7 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 returned in a Satellite Recovery Vehicle. The Satellite Recovery Vehicle used by Discoverer 17 was SRV-507. Shortly after Discoverer 17 began operations, its SRV separated prematurely. Two days after launch it was deorbited and recovered, however only centimetre (in) of film was found to be aboard, and no images were taken. Following the separation of the SRV, Discoverer 17 remained in orbit until it decayed on 29 December 1960. In addition to its reconnaissance payload, Discoverer 17 also carried a biological research payload, intended to investigate human tissues in space. Since at the time the United States did not publicly acknowledge its reconnaissance satellite programmes, this was officially the satellite's primary mission. Unexpectedly high radiation levels during the flight led to the data from this experiment being considered particularly valuable by US Air Force scientists.
