Spacecraft
editIts primary missions were to develop systems for future satellites, and to record data about cosmic rays and radiation.[3] It had a mass of 285 kg.[1]
Mission
editIt was launched aboard Kosmos-2I 63S1 s/n 5LK.[4] It was the fourth flight of the Kosmos-2I, and the second to successfully reach orbit. The launch was conducted from Mayak-2 at Kapustin Yar, and occurred at 17:16:00 GMT on 6 April 1962.[5] Kosmos 2 was placed into a low Earth orbit with a perigee of 215 kilometres (134 mi), an apogee of 1,488 kilometres (925 mi), an inclination of 49.0°, and an orbital period of 102.5 minutes.[2] It decayed on 20 August 1963.[6]
Kosmos 2 was a 1MS satellite, the first of two to be launched.[3] The second was launched on 25 October 1962 but failed to reach orbit. The 1MS was the first of two types of MS satellite to be launched and was succeeded by the 2MS satellite.[7]
