Lockheed Martin has been chosen by the U.S. Air Force to develop the Space Fence, which will detect smaller orbital debris than currently done under an Air Force system installed in 1961. This system was deemed a priority because space debris endangers the ISS and other satellites. Once constructed, the Space Fence should be able to detect debris as small as the size of a baseball, as compared to the current system that detects items the size of a basketball. Some of the junk now in space includes old satellites, rocket boosters and even a tool bag that drifted away from an astronaut at the space station.
