Kosmos 115 (Russian: Космос 115 meaning Cosmos 115) or Zenit-2 No.35 was a Soviet, first generation, low resolution, optical film-return reconnaissance satellite launched in 1966. A Zenit-2 spacecraft, Kosmos 115 was the thirty-seventh of eighty-one such satellites to be launched[4][5] and had a mass of 4,730 kilograms (10,430 lb).

Kosmos 115 was launched by a Vostok-2 rocket[6] flying from Site 31/6 at the Baikonur Cosmodrome. The launch took place at 10:48 GMT on 20 April 1966,[7] and following its successful arrival in orbit the spacecraft received its Kosmos designation; along with the International Designator 1966-033A and the Satellite Catalog Number 02147.[1]

Kosmos 115 was operated in a low Earth orbit, at an epoch of 22 April 1966, it had a perigee of 201 kilometres (125 mi), an apogee of 294 kilometres (183 mi), an inclination of 65.0° and an orbital period of 89.3 minutes.[3][8] After eight days in orbit, Kosmos 115 was deorbited, with its return capsule descending under parachute and landing at 09:07 GMT on 28 April 1966 and the capsule was recovered by Soviet force. There was abnormal operation of a SA-10 camera. Due to a camera malfunction, the satellite failed to take all of the images it had been programmed to produce.[2]
