Air Force Research Lab’s Directed Energy Directorate at Kirtland AFB, N.M., in concert with Boeing, has demonstrated that a dual-mirror system can redirect a laser to a target, extending the laser’s range. Using a prototype called the Aerospace Relay Mirror System, researchers successfully tested a non-lethal laser beam by firing it a one of two mirrors from several miles away and then using the second mirror to relay the beam to a ground-based target another two miles away. In this test, a crane hoisted the two mirrors up about 100 feet. In a real application, a high-altitude airship could loft the mirrors to some 70,000 feet, where there would be little atmospheric turbulence to affect beam quality.
The U.S. could lose its ability to effectively operate in space without action to lower the number of objects in low Earth orbit, top U.S. generals said. Vice Chief of Space Operations Gen. David D. Thompson said his biggest concern was not debris from objects currently in orbit but the…
