Satellite Collision in Space

Posted by Lydia on February 12th, 2009

A US Iridium communications satellite and a non-operational Russian (Cosmos 2251) satellite collided 490 ft above the earth over Siberia Tuesday causing a large debris field in space.

Although it is believed that the International Space Station is not in danger of interacting with the debris field, NASA is keeping a wide-open-eye on the situation in case smaller satellites may be compromised. All of the debris should eventually burn up in our atmosphere. Only three smaller satellites have ever suffered the same fate.
