Kosmos 99 (Russian: Космос 99 meaning Cosmos 99) or Zenit-2 No.32 was a Soviet, first generation, low resolution, optical film-return reconnaissance satellite launched in 1965. A Zenit-2 spacecraft, Kosmos 99 was the thirty-second of eighty-one such satellites to be launched [3] and had a mass of 4,730 kilograms (10,430 lb).

Kosmos 99 was launched by a Vostok-2 rocket, serial number U15001-04,[4] flying from Site 31/6 at the Baikonur Cosmodrome. The launch took place at 08:09 GMT on 10 December 1965.[5] Following its successful arrival in orbit the spacecraft received its Kosmos designation; along with the International Designator 1965-103A and the Satellite Catalog Number 01817.

Kosmos 99 was operated in a low Earth orbit, at an epoch of 10 December 1965, it had a perigee of 203 kilometres (126 mi), an apogee of 309 kilometres (192 mi), an inclination of 65.0° and an orbital period of 89.6 minutes.[6] On 18 December 1965, after eight days in orbit, the satellite was deorbited with its return capsule descending by parachute for recovery by the Soviet force.[7]
