Kosmos 28 (Russian: Космос 28 meaning Cosmos 28) or Zenit-2 No.16 was a Soviet optical film-return reconnaissance satellite which was launched in 1964. A Zenit-2 spacecraft, Kosmos 28 was the sixteenth of eighty-one such satellites to be launched[4][5] and had a mass of 4,730.0 kilograms (10,427.9 lb).[1]
A Vostok-2 rocket, serial number G15001-04,[6] was used to launch Kosmos 28. The launch took place at 09:36 UTC on 4 April 1964 from Site 31/6 at the Baikonur Cosmodrome.[2] Following its successful arrival in orbit the spacecraft received its Kosmos designation, along with the International Designator 1964-017A and the Satellite Catalog Number 779.[1]
Kosmos 28 was operated in a low Earth orbit. On 6 April 1964 it had a perigee of 205 kilometres (127 mi), an apogee of 378 kilometres (235 mi), with inclination of 65 degrees and an orbital period of 90.34 minutes. On 12 April 1964 the spacecraft was deorbited, with its return capsule descending by parachute for recovery by Soviet forces.[3][5]
