Kosmos 108 (Russian: Космос 108 meaning Cosmos 108), also known as DS-U1-G No.1, was a Soviet satellite which was launched in 1966 as part of the Dnepropetrovsk Sputnik programme. It was a spacecraft, which was built by the Yuzhnoye Design Office and was used to study the effects of solar activity on the upper atmosphere.[3]
A Kosmos 63S1 carrier rocket was used to launch Kosmos 108 into low Earth orbit. The launch took place from Site 86/1 at Kapustin Yar.[4] The launch occurred at 18:00 GMT on 11 February 1966, and resulted in the successfully insertion of the satellite into low Earth orbit.[5] Upon reaching orbit, the satellite was assigned its Kosmos designation, and received the International Designator 1966-011A.[6] The North American Air Defense Command assigned it the catalogue number 02002.
Kosmos 108 was the first of two DS-U1-G satellites to be launched, the other being Kosmos 196 (19 December 1967).[7] It was operated in an orbit with a perigee of, an apogee of, an inclination of 48.9°, and an orbital period of 95.3 minutes. It completed operations on 26 February 1966.[8] On 21 November 1966, it decayed from orbit and reentered the atmosphere.[9]
