Lockheed Martin moves forward with Space Fence program
Moorestown, N.J. (UPI) Sep 28, 2015
U.S. government officials approved Lockheed Martin's design for their Space Fence system, which includes a large-scale digital radar and a turn-key facility, the company announced today. The Space Fence is a next-generation space surveillance system being built by the U.S. Air Force. Its purpose is to monitor both artificial satellites and space debris that orbit Earth. The plans were based on an earlier system called the Air Force Space Surveillance System, but those plans were abandoned in 20 ... read more
