    NASA spacecraft will use fuel that's safer for humans

    Many spacecraft depend on hydrazine in their fuel, but it's extremely hazardous -- and that means very careful fueling processes that slow things down. NASA will soon have a safer option, however. It's about to test-fly the Green Propellant Infusion Mission, a spacecraft that ditches hydrazine in favor of a namesake "green" mix of hydroxyl ammonium nitrate with an oxidizer that lets it burn. It's safe enough that you could fuel a spacecraft while you're still building it, speeding up the launch process.

  • The Air Force will have combat lasers on its war planes by 2020

    The Army has its HEL-MD (not to mention is working on GI Joe-style rifles and minesweepers); the Navy put a battleship-mounted railgun aboard the USS Ponce; and within the next five years, the Air Force expects to have laser weapons of its very own. These armaments, dubbed directed-energy weapons pods, will be mounted on American warplanes and serve to burn missiles, UAVs -- even other combat aircraft -- clean out of the sky. "I believe we'll have a directed energy pod we can put on a fighter plane very soon," Air Force General Hawk Carlisle said at a Fifth-Generation Warfare lecture during the Air Force Association Air & Space conference earlier this week. "That day is a lot closer than I think a lot of people think it is."

  • US Air Force orders up 2,200 more PS3s -- for thinking, not gaming

    We were as surprised as anyone when the USAF threw down the cash for 300-odd PlayStation 3s back in March of last year, but what's more shocking is that it's now back for more -- seven times more, in fact. Already employing its PS3 cluster for research into high-def video processing, the Air Force Research Lab wants to expand its capabilities significantly and it seems that Sony's Cell processor is still its weapon of choice. We would use this opportunity to make a few jibes about lazy engineers upgrading their setups in time for Modern Warfare 2, but we're better than that. We'll also totally avoid noting that the US government's skimping on costs now is leading it to commit to an instruction set tailored specifically to the Cell processor, which contrary to the latest Xeons -- pricier though they may be -- is not guaranteed to keep updating in pace with the USAF's needs. Those are things we'll leave for someone who isn't afraid of death lasers and autonomous attack drones to say.

  • Boeing to develop microwave-based airborne EMP weapon

    Boeing's been busy with the high-tech death lately -- just a week after the company announced the Phantom Ray fighter UAV, it's back in the news with a high-powered airborne microwave weapon designed to knock out enemy electronics. The goal is to more or less destroy the enemy's tech with out having to set off one of those pesky nuclear explosions necessary for an EMP, and Boeing plans to test the tech out both in the air and on the ground several times over the next three years as part of the Air Force's Counter-electronics High power microwave Advanced Missile Project (CHAMP) project. We'll be ready with the popcorn. [Via The Register]

  • Air Force developing UAVs that can recharge on power lines

    We've seen some interesting solutions to keeping UAVs powered for extended missions, but none so diabolical as actually landing on the enemy's power lines and using their juice to power up. That's the plan behind the Power Line Urban Sentry (PLUS) project currently being run by the Air Force Research Laboratory and private firm Defense Research Associates, and it's already yielded UAVs that can land on power lines and charge in three hours. The project started with attempts to charge by simply flying near power lines, but when that method yielded only micro-watts of juice, focus shifted to actually landing on the lines. The team is planning all sorts of other capabilities for the tech, including navigation systems -- "Power lines are like highways in the sky," says one of the researchers -- and auxiliary surveillance systems that power up when jacked in. On top of all that awesomeness, the team is also working with an outfit called the Center for Morphing Control to disguise the UAVs when they sit on the lines -- so far, they say, they've made a small UAV "look like a Coke can." Test flights are scheduled for 2008, and there's still work to be done on the power line latching mechanism, but whatever -- we want one.[Thanks, Stuart T., original photo by Bob Fornal]
