First hypervelocity spacecraft collision

First hypervelocity spacecraft collision
On February 10, 2009, two communications satellites—the active commercial Iridium 33 and the derelict Russian military Kosmos 2251—accidentally collided at a speed of 11.7 km/s (26,000 mph) and an altitude of 789 kilometres (490 mi) above the Taymyr Peninsula in Siberia. It was the first time a hypervelocity collision had occurred between two satellites; previous incidents had involved a satellite and a piece of space debris.
