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 kilograms (589 lb) spacecraft, which was built by the Yuzhnoye Design Bureau, and used to conduct tests involving atomic clocks.[4]

A Kosmos-2M 63S1M[5] carrier rocket was used to launch Kosmos 97 into low Earth orbit. The launch took place from Site 86/1 at Kapustin Yar.[6] The launch occurred at 12:14 GMT on 26 November 1965, and resulted in the successful insertion of the satellite into orbit.[7] Upon reaching orbit, the satellite was assigned its Kosmos designation, and received the International Designator 1965-095A. The North Americn Air Defense Command assigned it the catalogue number 01777.

Kosmos 97 contained the first experiments with measuring masers. A molecular quantum generator was tested, which makes it possible to communicate with and control other spacecraft, and to send information great distances. Aspects of the Theory of Relativity were also tested.[8]

Kosmos 97 was the first of two DS-U2-M satellites to be launched, the other being Kosmos 145.[9] It was operated in an orbit with a perigee of 213 kilometres (132 mi), an apogee of 2,144 kilometres (1,332 mi), an inclination of 49.0°, and an orbital period of 108.3 minutes. On 2 April 1967, it decayed from orbit and reentered the atmosphere.[10]
