Kosmos 3 (Russian:Космос 3 meaningCosmos 3), also known as2MS No.1 and occasionally in the West asSputnik 13 was a scientific research and technology demonstrationsatellite launched by theSoviet Union in 1962.
It was the third satellite to be designated under theKosmos system, and the first spacecraft to be launched as part of the2MS programme. Its primary missions were to develop systems for future satellites, and to record data aboutcosmic rays andradiation.[3]
Kosmos 3, an automatic geophysical station, was one of a series of Soviet Earth satellites whose purpose was to study outer space, the upper layers of the atmosphere, and the Earth. Scientific data and measurements were relayed to Earth by multichannel telemetry systems equipped with space-borne memory units. It had a mass of 330 kg.[1]
It was launched aboardKosmos-2I 63S1s/n 4LK.[4] It was the fifth flight of the Kosmos-2I, and the third to successfully reach orbit. The launch was conducted fromMayak-2 atKapustin Yar, and occurred at 04:04:00GMT on 24 April 1962.[5] Kosmos 3 was placed into alow Earth orbit with aperigee of 216 kilometres (134 mi), anapogee of 707 kilometres (439 mi), aninclination of 49.0°, and anorbital period of 93.8 minutes.[2] Itdecayed on 17 October 1962.[6]
Kosmos 3 was a2MS satellite, the first of two to be launched.[3] The second,2MS No.2, would be launched asKosmos 5 on 28 May 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.[7]
