Kosmos 68 (Russian: Космос 68 meaning Cosmos 68) or Zenit-2 No.28 was a Soviet, first generation, low resolution, optical film-return reconnaissance satellite launched in 1965.

A Zenit-2 spacecraft, Kosmos 68 was the twenty-eighth of eighty-one such satellites to be launched[4][5] and had a mass of 4,730 kilograms (10,430 lb).

Kosmos 68 was launched by a Vostok-2 rocket, serial number U15001-01,[6] flying from Site 31/6 at the Baikonur Cosmodrome.

Kosmos 68 was operated in a low Earth orbit; at an epoch of 17 June 1965 it had a perigee of 209 kilometres (130 mi), an apogee of 315 kilometres (196 mi), an inclination of 65.0° and an orbital period of 89.8 minutes.

On 23 June 1965, after eight days in orbit, the satellite was deorbited with its return capsule descending by parachute for recovery by Soviet forces.
