Today Northrop Grumman said it grabbed $30 million from the USAir Force to start developing the first phase of a global space surveillance ground radar system. The new S-Band Space Fence is part of the Department of Defense's effort to track and detect what are known as resident space objects (RSO), consisting of thousands of pieces of space debris as well as commercial and military satellites. The new Space Fence will replace the current VHF Air Force Space Surveillance System built in 1961.
