Iridium 33 was a communications satellite launched by the United States for Iridium Communications. 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. [2] [3] It was operated in Plane 3 of the Iridium satellite constellation, with an ascending node of 230.9°. [2]

Destruction

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. [4] NASA reported that a large amount of space debris was produced by the collision. [5] [6] [7] [8]
