Green Satellite Fuel Designed To Make Space SaferParis, France (ESA) Mar 17, 2010 On the day running up to launch when a spacecraft is fuelled, ground personnel look more like astronauts than engineers, putting on spacesuit-like protective gear. This is an essential precaution when dealing with the current hydrazine fuel, but a new development could make satellite fuelling no more dangerous than filling up a car. First used in rocket engines by the German Luftwaffe during World War Two, hydrazine remains the main propellant of choice for a satellite's onboard thrusters, u ... read more |

Ultra-Powerful Laser Makes Silicon Pump Liquid Uphill With No Added EnergyRochester NY (SPX) Mar 17, 2010 In a paper in the journal Optics Express, professor Chunlei Guo and his assistant Anatoliy Vorobyev demonstrate that by carving intricate patterns in silicon with extremely short, high-powered laser bursts, they can get liquid to climb to the top of a silicon chip like it was being sucked through a straw. Unlike a straw, though, there is no outside pressure pushing the liquid up; it rises on its own accord. By creating nanometer-scale structures in silicon, Guo greatly increases the attraction t ... read more |
