Launch
editKosmos 706 was launched from Site 41/1 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 15:02 UTC on 30 January 1975.[3] The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 1975-007A.[4] The United States Space Command assigned it the Satellite Catalog Number 7625.[4]
