Discoverer 26, also known as Corona 9019, was an American optical
The launch of Discoverer 26 occurred at 23:29:48 UTC on 7 July 1961. A
Vandenberg Air Force Base.[2] Upon successfully reaching orbit, it was assigned the Harvard designation
1961 Pi 1.
Discoverer 26 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, which was deorbited two days after launch. The Satellite Recovery Vehicle used by Discoverer 26 was SRV-511. Once its images had been returned, Discoverer 26's mission was complete, and it remained in orbit until it decayed on 5 December 1961.[3]
