Two satellites collide in orbit
BY WILLIAM HARWOOD Posted: February 11, 2009 In an unprecedented space collision, a commercial Iridium communications satellite and a presumably defunct Russian Cosmos satellite ran into each other Tuesday above northern Siberia, creating a cloud of wreckage, officials said today.

Photo: Iridium The international space station does not appear to be threatened by the debris, they said, but it's not yet clear whether it poses a risk to any other military or civilian satellites. "They collided at an altitude of 790 kilometers (491 miles) over northern Siberia Tuesday about noon Washington time," said Nicholas Johnson, NASA's chief scientist for orbital debris at the Johnson Space Center in Houston. "The U.S. space surveillance network detected a large number of debris from both objects."

Speculation: Maybe Cosmos 2251 very recently suffered an (undetected) fragmentation and the debris cloud intersected with Iridium's orbit.
