Kosmos 5 (Russian:Космос 5 meaningCosmos 5), also known as2MS #2 and occasionally in the West asSputnik 15 was a scientific research and technology demonstrationsatellite launched by theSoviet Union in 1962. It was the fifth satellite to be designated under theKosmos system, and the third spacecraft to be launched as part of theMS programme, afterKosmos 2 andKosmos 3. Its primary missions were to develop systems for future satellites, and to record data about artificialradiation around the Earth.[3]
Kosmos 5 was a2MS satellite, the second of two to be launched,[3] following the first which was launched asKosmos 3 on 24 April 1962. The 2MS was the second of two types of MS satellite to be launched, following the first1MS spacecraft which had been launched asKosmos 2. Kosmos 5 was the penultimate MS satellite to be launched, and the last to successfully reach orbit. The last launch attempt, of a 1MS satellite, occurred on 25 October 1962, and failed to reach orbit.[4] It had a mass of 280 kg.[1]
It was launched aboardKosmos-2I 63S1s/n 3LK.[5] It was the sixth flight of the Kosmos-2I, and the fourth to successfully reach orbit. The launch was conducted fromMayak-2 atKapustin Yar, and occurred at 03:07:00GMT on 28 May 1962.[6] Kosmos 5 was placed into alow Earth orbit with aperigee of 190 kilometres (120 mi), anapogee of 1,587 kilometres (986 mi), aninclination of 49.1°, and anorbital period of 102.8 minutes.[2] Itdecayed on 2 May 1963, after nearly a year in orbit.[7]
Kosmos 5 was among several satellites inadvertently damaged or destroyed by theStarfish Primehigh-altitude nuclear test on 9 July 1962 and subsequentradiation belt.
