Submission + - Laser weapon shoots down airplanes in test (defpro.com)

airshowfan writes: Boeing's directed-energy weapons (a.k.a. frickin' laser beams) have been getting some attention lately. The Advanved Tactical Laser (ATL) is a C-130 that famously burned a hole through a car's hood, and the YAL-1 AirBorne Laser (ATL) is a 747 that shoots a laser from its nose that is powerful enough to bring down an ICBM. But even cooler is the Mobile Active Targeting Resource for Integrated eXperiments (MATRIX), a laser that is mounted on a truck (which probably costs less than a 747, but who knows) and that can shoot down small aircraft, as shown in the picture on this article. (The Laser Avenger supposedly also has this capability). We live in the future!
Space

Submission + - Orbital Express launches tonight

airshowfan writes: "When a geosynchronous satellite is launched into space, no human ever gets to touch it again. This means that, other than for minor software issues, there is no way to fix it if it breaks, so it has to work perfectly, almost autonomously, for 20 years non-stop. There is also no way to refuel it once it's out of thruster fuel, the reason why it can't last more than 20 years even if it gets to that mark working very well, with batteries and solar cells still going, which is often the case. If only there were a robotic spacecraft in geostationary orbit that could change broken satellite components and refuel those older satellites, then satellites would be a lot less risky and would last a lot longer. Does this robotic spacecraft mechanic sound like science fiction? It launches tonight."
