Kosmos 137 (Russian: Космос 137 meaning Cosmos 137), also known as DS-U2-D No.1, was a Soviet satellite which was launched in 1966 as part of the Dnepropetrovsk Sputnik programme. It was a 237-kilogram (522 lb) spacecraft,[1] which was built by the Yuzhnoye Design Bureau, and was used to investigate charged particles in the Earth's magnetosphere.[2]

A Kosmos-2I 63S1 carrier rocket was used to launch Kosmos 137 into low Earth orbit. The launch took place from Site 86/1 at Kapustin Yar.[3] The launch occurred at 13:11:59 GMT on 21 December 1966, and resulted in the successful insertion of the satellite into orbit.[4] Upon reaching orbit, the satellite was assigned its Kosmos designation, and received the International Designator 1966-117A.[5] The North American Aerospace Defense Command assigned it the catalogue number 02627.

Kosmos 137 was the first of two DS-U2-D satellites to be launched,[2] and was followed by Kosmos 219.[6] It was operated in an orbit with a perigee of 221 kilometres (137 mi), an apogee of 1,622 kilometres (1,008 mi), 48.8 degrees of inclination, and an orbital period of 103.45 minutes.[7] It completed operations on 12 May 1967,[1] before decaying from orbit and reentering the atmosphere on 23 November.[7]
