Space Fence program enters next phase – and then there were two

Space Fence program enters next phase – and then there were two: "The U.S. Air Force’s Space Fence program has entered its next phase with the three companies originally awarded US$30 million contracts to develop a Space Fence now cut back to two. Northrop Grumman is now out of the project, leaving Lockheed Martin and Raytheon, which have each been awarded a US$107 million dollar follow-on contract to further develop and prototype their systems in preparation for a final Space Fence production contract next year. As might be easy to misconstrue from its name, the Space Fence isn’t designed as a defense against intergalactic interlopers, but is intended to detect and track the increasing amount of space junk orbiting Earth."
