A Zenit-2 spacecraft, Kosmos 29 was the seventeenth of eighty-one such satellites to be launched[3] and had a mass of 4,780 kilograms (10,540 lb).
Kosmos 29 was operated in a low Earth orbit. On 25 April 1964, it had a perigee of 203 kilometres (126 mi), an apogee of 296 kilometres (184 mi), 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]
