Kosmos 1785 (Russian: Космос 1785 meaning Cosmos 1785) is a Soviet US-K missile early warningsatellite which was launched in 1986 as part of the Soviet military's Oko programme. The satellite is designed to identify missile launches using optical telescopes and infrared sensors.[2]
Kosmos 1785 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 09:29 UTC on 15 October 1986.[3] The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 1986-078A.[3] The United States Space Command assigned it the Satellite Catalog Number 17031.[3]
It re-entered the Earth's atmosphere on 28 February 2002.[4]
