Kosmos 104 (Космос 104 meaning Cosmos 104) or Zenit-2 No.36 was a Soviet first-generation low-resolution optical film–return reconnaissance satellite launched in 1966. A Zenit-2 spacecraft, Kosmos 104 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 104 was launched by a Vostok-2 rocket [4] from Site 31/6 at the Baikonur Cosmodrome. The launch took place at 08:24 GMT on 7 January 1966; [5] however, the program was not completely met. The spacecraft was put into an incorrect orbit by malfunctions in the booster rocket's second and third stages. [6] The spacecraft received a Kosmos designation, along with the International Designator 1966-001A and the Satellite Catalog Number 01903. [7]
Despite the problem during its launch, Kosmos 104 was able to complete most of its imaging mission. Its orbit, at an epoch of 7 January 1966, had a perigee of 193 kilometres (120 mi), an apogee of 380 kilometres (240 mi) inclination of 65.0° and a period of 90.2 minutes. [8] On 15 January 1966, after eight days in orbit, the satellite was deorbited with its return capsule descending by parachute for a successful recovery by Soviet force. [9]
