Kosmos 97 (Russian: Космос 97 meaning Cosmos 97), also known as DS-U2-M No.1, was a Soviet satellite which was launched in 1965 as part of the Dnepropetrovsk Sputnik programme. It was a 267-kilogram (589 lb) spacecraft,[2] which was built by the Yuzhnoye Design Bureau, and used to conduct tests involving atomic clocks.[2]

A Kosmos-2M 63S1M[3] carrier rocket was used to launch Kosmos 97 into low Earth orbit. The launch took place from Site 86/1 at Kapustin Yar.[4] The launch occurred at 12:14 GMT on 26 November 1965, and resulted in the successful insertion of the satellite into orbit.[5] Upon reaching orbit, the satellite was assigned its Kosmos designation, and received the International Designator 1965-095A.[6] The North American Aerospace Defense Command assigned it the catalogue number 01777.

Kosmos 97 was the first of two DS-U2-M satellites to be launched, the other being Kosmos 145.[2][7] It was operated in an orbit with a perigee of 217 kilometres (135 mi), an apogee of 2,020 kilometres (1,260 mi), 48.4 degrees of inclination, and an orbital period of 107.7 minutes.[8] On 2 April 1967, it decayed from orbit and reentered the atmosphere.[8]
