NASA has completed a 43,000 hour stress test -- a record for ion thrusters -- on a new rocket propulsion system that could extend future space travel to farther reaches of the solar system.
Developed by NASA's Evolutionary Xenon Thruster Project, the 7-kilowatt ion thruster can burn 10-12 times longer than the conventional chemical thrusters used today. Though not practical for manned-spaceflight, the system could power exploratory rockets that reach outer planets and their moons.
