Kosmos 29 (Russian: Космос 29 meaning Cosmos 29) or Zenit-2 No.17 was a Soviet, a first generation, low resolution, optical film-return reconnaissance satellite which was launched in 1964. A Zenit-2 spacecraft, Kosmos 29 was the seventeenth of eighty-one such satellites to be launched[3] and had a mass of 4780kg (10,540lb).
A Vostok-2 rocket, serial number R15001-01,[4] was used to launch Kosmos 29. The launch took place at 10:19 GMT on 25 April 1964, using Site 31/6 at the Baikonur Cosmodrome.[5] Following its successful arrival in orbit the spacecraft received its Kosmos designation, along with the International Designator 1964-021A and the Satellite Catalog Number 00791.[6]
Kosmos 29 was operated in a low Earth orbit. On 25 April 1964, it had a perigee of 203km (126miles), an apogee of 296km (184miles), with inclination of 65.1° and an orbital period of 89.5 minutes. After eight days in orbit, the satellite was deorbited on 3 May 1964 with its return capsule descending by parachute for recovery by Soviet forces.[7] [8]
