Kosmos 2261 (Russian: Космос 2261 meaning Cosmos 2261) is a Russian US-K missile early warning satellite which was launched in 1993 as part of the Russian Space Forces' Oko programme. The satellite is designed to identify missile launches using optical telescopes and infrared sensors.[2] It was estimated in the west that it stopped functioning in March 1998,[5] and reentered destructively on December 31, 2012.[6] (the early morning of January 1, 2013 in some time zones)

Quick Facts Mission type, COSPAR ID ...

Kosmos 2261 was launched from Site 16/2 at Plesetsk Cosmodrome in Russia.[7] A Molniya-M carrier rocket with a 2BL upper stage was used to perform the launch, which took place at 14:53 UTC on 10 August 1993.[3] The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 1993-051A.[3] The United States Space Command assigned it the Satellite Catalog Number 22741.[3]

Its predicted re-entry time was December 31, 2012 at 11:29 UTC ± 2 hours.[6]
