Kosmos 28 (Russian: Космос 28 meaning Cosmos 28) or Zenit-2 No.16 was a Soviet, a first generation, low resolution, 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[3][4] and had a mass of 4,730 kilograms (10,430 lb).

A Vostok-2 rocket, s/n G15001-04,[5] was used to launch Kosmos 28. The launch took place at 09:36 GMT on 4 April 1964 from Site 31/6 at the Baikonur Cosmodrome.[6] Following its successful arrival in orbit the spacecraft received its Kosmos designation, along with the International Designator 1964-017A and the Satellite Catalog Number 00779.

Kosmos 28 was operated in a low Earth orbit. On 4 April 1964, it had a perigee of 213 kilometres (132 mi), an apogee of 373 kilometres (232 mi), with inclination of 65.0° and an orbital period of 90.4 minutes. On 12 April 1964, the spacecraft was deorbited, with its return capsule descending by parachute for recovery by Soviet forces.[7][4]
