A Russian And An American Satellite Collide Over Siberia 

The 2009 satellite collision was the first major collision between two intact artificial satellites in Earth orbit. The collision occurred at 16:56 UTC on February 10, 2009, at 789 kilometres (490 mi) above the Taymyr Peninsula in Siberia, when Iridium 33 and Kosmos-2251 collided. The satellites collided at a speed of 11.7 kilometres per second (7.3 mi/s), or approximately 42,120 kilometres per hour (26,170 mph).

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. It was operated in Plane 3 of the Iridium satellite constellation, with an ascending node of 230.9°.

Kosmos-2251, (Russian: Космос-2251 meaning Cosmos 2251), was a Russian Strela-2M communications satellite. It was launched into Low Earth orbit from Site 132/1 at the Plesetsk Cosmodrome at 04:17 GMT on 16 June 1993, by a Kosmos-3M carrier rocket.
