Kosmos 1569 was launched from Site 16/2 at Plesetsk Cosmodrome in the Russian SSR.[3] A Molniya-M carrier rocket with a 2BL upper stage was used to perform the launch, which took place at 15:34 UTC on 6 June 1984.[3] The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 1984-055A.[4] The United States Space Command assigned it the Satellite Catalog Number 15027.[4]
It re-entered the Earth's atmosphere on 7 May 2001.[4]
