On February 10th 2009 two satellites collided over Northern Siberia. David Wright, the co-director of the Union of Concerned Scientists' Global Security Program and a nationally recognized satellite expert, points out in a backgrounder posted on UCS's Web site that this collision will significantly increase the amount of debris in an area of space that is the most crowded and has the greatest risk of collisions.
