The launch of Discoverer 30

Discoverer 30, also known as Corona 9022, was an American optical reconnaissance satellite which was launched in 1961. It was a KH-3 Corona''' satellite, based around an Agena-B.[1]

The launch of Discoverer 30 occurred at 19:59 UTC on 12 September 1961. A Thor DM-21 Agena-B rocket was used, flying from Launch Complex 75-3-5 at the Vandenberg Air Force Base.[2] Upon successfully reaching orbit, it was assigned the Harvard designation 1961 Omega 1.

Discoverer 30 was operated in a low Earth orbit, with a perigee of 231 kilometres (144 mi), an apogee of 484 kilometres (301 mi), 82.6 degrees of inclination, and a period of 91.7 minutes.[3] The satellite had a mass of 1,150 kilograms (2,500 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-millimetre (2.8 in) film, and returned in a Satellite Recovery Vehicle two days after launch however, like the previous mission, all of the images returned were found to be out of focus.[4] The Satellite Recovery Vehicle used by Discoverer 30 was SRV-551. Once its images had been returned, Discoverer 30's mission was complete, and it remained in orbit until its decay on 11 December 1961.[3]
