Kosmos 1409 ( Russian: Космос 1409 meaning Cosmos 1409) was a Soviet US-K missile early warning satellite which was launched in 1982 as part of the Soviet military's Oko programme. [4] Kosmos 1409 replaced Kosmos 1217 as part of the Oko constellation of satellites and covered the plane 2 - 317° longitude of ascending node. [5]
Mission
The satellite was designed to identify missile launches using optical telescopes and infrared sensors. [4]
Launch
Kosmos 1409 was launched from Site 16/2 from Plesetsk Cosmodrome in Soviet Union. [2] A Molniya-M launch vehicle with a Blok 2BL upper stage was used to perform the launch, which took place at 06:23:11 UTC on 22 September 1982. [2] The launch successfully placed the satellite into a Molniya orbit. It subsequently received its Kosmos designation, and the COSPAR International Designator 1982-095A. [6] The United States Space Command assigned it the Satellite Catalog Number 13585. [6]
Atmospheric entry
It reentered the Earth's atmosphere on 8 June 2009. [6]
