Kosmos 1977 was launched from Site 41/1 at Plesetsk Cosmodrome in the Russian SSR.[5] A Molniya-M carrier rocket with a 2BL upper stage was used to perform the launch, which took place at 18:02 UTC on 25 October 1988.[3] The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 1988-096A.[3] The United States Space Command assigned it the Satellite Catalog Number 19608.[3]
