Kosmos 12 (Russian: Космос 12 meaning Cosmos 12) or Zenit-2 No.6 was a Soviet optical film-return reconnaissance satellite launched in 1962. A Zenit-2 spacecraft, Kosmos 12 was the seventh of eighty-one such satellites to be launched.[3][4]


Kosmos 12 was a Zenit-2 satellite, a first generation, low resolution, reconnaissance satellite derived from the Vostok spacecraft used for crewed flights, the satellites were developed by OKB-1. In addition to reconnaissance, it was also used for research into radiation in support of the Vostok programme. It had a mass of 4,730 kilograms (10,430 lb).[1]


The Vostok-2 rocket, serial number T15000-10, was used to launch Kosmos 12. The launch took place from Site 1/5 at the Baikonur Cosmodrome at 09:21:00 GMT on 22 December 1962. Following its successful arrival in orbit, the spacecraft received its Kosmos designation, along with the Harvard designation 1962 Beta Omega 1, the International Designator 1962-072A, and the Satellite Catalog Number 00517.[1]

Kosmos 12 was operated in a low Earth orbit. On 22 December 1962, it had a perigee of 198 kilometres (123 mi), an apogee of 392 kilometres (244 mi), with an inclination of 65.0°, and an orbital period of 90.5 minutes.[2] On 30 December 1962, the spacecraft was deorbited, with its return capsule descending by parachute for recovery by the Soviet forces in the steppe in Kazakhstan.
