Space debris becoming a problem
A four-inch fragment of a destroyed Chinese satellite has forced members of the space shuttle Discovery to maneuver itself, and the International Space Station it's linked to, out of the piece's path. A University of Minnesota expert who can explain the increasing problem of space debris is:
Bill Garrard, aerospace engineering and mechanics professor at the University of Minnesota
Since 1957 more than 6,000 satellites have been launched into space but today only an estimated 800 are functional. Garrard can discuss how the considerable amount of debris already in space has been created and the ways it poses a danger to space operations in orbits near Earth. Garrard is the director of the NASA Funded Minnesota Space Grant Consortium.
