Kosmos 52 was launched by a Vostok-2 rocket, serial number R15002-03,[4] flying from Site 31/6 at the Baikonur Cosmodrome. The launch took place at 09:36 GMT on 11 January 1965,[5] with the spacecraft receiving its Kosmos designation - along with the International Designator 1965-001A and the Satellite Catalog Number 00968 - upon its successful insertion into orbit. It was the first satellite to be launched in the year 1965.
Kosmos 52 was operated in a low Earth orbit. On 11 January 1965 it had a perigee of 203 kilometres (126 mi), an apogee of 298 kilometres (185 mi), an inclination of 65.0° and an orbital period of 89.5 minutes.[6] On 19 January 1965, eight days after launch, Kosmos 52 was deorbited so that its return capsule could be recovered by Soviet forces and its photos developed and analysed.[7]
