Kosmos 105 (Russian: Космос 105 meaning Cosmos 105) or Zenit-2 No.34 was a Soviet, first generation, low resolution, optical film-return reconnaissance satellite launched in 1966. A Zenit-2 spacecraft, Kosmos 105 was the thirty-fourth of eighty-one such satellites to be launched[3] and had a mass of 4730kg (10,430lb).
Kosmos 105 was launched by a Vostok-2 rocket[4] flying from Site 31/6 at the Baikonur Cosmodrome. The launch took place at 08:38 GMT on 22 January 1966,[5] and following its successful arrival in orbit the spacecraft received its Kosmos designation, along with the International Designator 1966-003A and the Satellite Catalog Number 01945.[6]
Kosmos 105 was operated in a low Earth orbit; at an epoch of 22 January 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.[7] On 30 January 1966, after eight days in orbit, the satellite was deorbited with its return capsule descending by parachute for recovery by Soviet force.[8]
