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. Iridium satellite An artist's concept of an Iridium satellite orbiting the Earth. 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."

It will be interesting to see how (or if) regulatory bodies will respond. (For that matter, what regulatory body would have jurisdiction? The US government could make laws requiring the US companies to take precautions, but they have no authority over non-US companies, or the space agencies of other nations. It seems unlikely that the UN will respond, but you never know...)
