Kosmos 862 ( Russian: Космос 862 meaning Cosmos 862) was a Soviet US-K missile early warning satellite which was launched in 1976 as part of the Soviet military's Oko programme. The satellite was designed to identify missile launches using optical telescopes and infrared sensors. [2]
Launch
Kosmos 862 was launched from Site 43/4 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 09:12 UTC on 22 October 1976. [3]
Orbit
The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 1976-105A. [4] The United States Space Command assigned it the Satellite Catalog Number 9495. [4]
The satellite self-destructed on March 15, 1977, breaking into 13 pieces of which several are still on orbit. [1] [5]
