Kosmos 107 (Russian: Космос 107 meaning Cosmos 107) or Zenit-2 No.35 was a Soviet, first generation, low resolution, optical film-return reconnaissance satellite launched in 1966. A Zenit-2 spacecraft, Kosmos 107 was the thirty-fifth of eighty-one such satellites to be launched[3] [4] and had a mass of 4730kg (10,430lb).
Kosmos 107 was launched by a Vostok-2 rocket[5] flying from Site 31/6 at the Baikonur Cosmodrome. The launch took place at 08:52 GMT on 10 February 1966,[6] and following its successful arrival in orbit the spacecraft received its Kosmos designation; along with the International Designator 1966-010A and the Satellite Catalog Number 01998.[7]
Kosmos 107 was operated in a low Earth orbit, at an epoch of 10 February 1966, it had a perigee of 204km (127miles), an apogee of 310km (190miles), an inclination of 65.0° and an orbital period of 89.7 minutes.[8] After eight days in orbit, Kosmos 107 was deorbited, with its return capsule descending under parachute, landing at 06:29 GMT on 18 February 1966, and recovered by Soviet force.[9]
