Kosmos 18 (Russian: Космос 18 meaning Cosmos 18) or Zenit-2 No.11 was a Soviet optical film-return reconnaissance satellite launched in 1963. A Zenit-2 satellite, Kosmos 18 was the eleventh of eighty-one such spacecraft to be launched.[3][4]

Spacecraft

Kosmos 18 was a Zenit-2 satellite, a first generation, low resolution, reconnaissance satellite derived from the Vostok spacecraft used for crewed flights, the satellites were developed by OKB-1. In addition to reconnaissance, it was also used for research into radiation in support of the Vostok programme. It had a mass of 4,730 kilograms (10,430 lb).[1]

Launch

The Vostok-2 rocket, serial number E15000-12,[5] was used to launch Kosmos 18. The launch took place at 10:48:00 GMT on 24 May 1963, using Site 1/5 at the Baikonur Cosmodrome.[1] Following its successful arrival in orbit the spacecraft received its Kosmos designation, along with the International Designator 1963-018A and the Satellite Catalog Number 00586.[1]

Mission

Kosmos 18 was operated in a low Earth orbit. On 24 May 1963, it had a perigee of 196 kilometres (122 mi), an apogee of 288 kilometres (179 mi), with an inclination of 65.0°, and an orbital period of 89.4 minutes.[2] Having spent nine days in orbit, the spacecraft was deorbited on 2 June 1963. Its return capsule descended under parachute and was recovered by the Soviet forces in the steppe in Kazakhstan.[4] In addition to its imaging mission, Kosmos 18 was used to conduct measurements of radiation levels in low Earth orbit.[1]
