Iridium 33 was a U.S. Iridium communications satellite. It was launched into low Earth orbit from Site 81/23 at the Baikonur Cosmodrome at 01:36 GMT on 14 September 1997, by a Proton-K carrier rocket with a Block DM2 upper stage.[1][2] It was operated in Plane 3 of the Iridium satellite constellation, with an ascending node of 230.9°.[1]


On 10 February 2009, at 16:56 GMT, Kosmos 2251 (a retired Strela satellite) and Iridium 33 collided, resulting in the destruction of both spacecraft.[3] NASA reported that a large amount of space debris was produced by the collision.[4][5][6]
