Kosmos 64 (Russian: Космос 64 meaning Cosmos 64) or Zenit-2 No.17 was a Soviet, first generation, low resolution, optical film-return reconnaissance satellite launched in 1965. A Zenit-2 satellite, Kosmos 64 was the twenty-sixth of eighty-one such spacecraft to be launched[3][4] and had a mass of 4,720 kilograms (10,410 lb).

Kosmos 64 was launched by a Vostok-2 rocket, serial number G15001-06,[5] flying from Site 31/6 at the Baikonur Cosmodrome. The launch took place at 10:04 GMT on 25 March 1965, and following its successful arrival in orbit the spacecraft received its Kosmos designation; along with the International Designator 1965-025A and the Satellite Catalog Number 01305.[1]

Kosmos 64 was operated in a low Earth orbit, on 25 March 1965 it had a perigee of 201 kilometres (125 mi), an apogee of 267 kilometres (166 mi), an inclination of 65.0° and an orbital period of 89.2 minutes. On 2 April 1965, after eight days in orbit, Kosmos 64 was deorbited with its return capsule descending by parachute for recovery by Soviet forces.[4]
