+ - NASA's NEXT ion thruster clocks up continuous operation world record->

Submitted by cylonlover
cylonlover (1921924) writes "NASA's Evolutionary Xenon Thruster (NEXT) ion engine has set a new world record by clocking up 43,000 hours of continuous operation at NASA’s Glenn Research Center’s Electric Propulsion Laboratory. The seven-kilowatt thruster is intended to propel future NASA deep space probes on missions where chemical rockets aren't a practical option. The NEXT ion thruster is one of NASA’s latest generation of engines. With a power output of seven kilowatts, it’s over twice as powerful as the ones used aboard the unmanned Dawn space probe. Yet it is simpler in design, lighter and more efficient, and is also designed for very high endurance.

Its current record of 43,000 hours is the equivalent of nearly five years of continuous operation while consuming only 770 kg (1697.5 lbs) of xenon propellant. The NEXT engine would provide 30 million-newton-seconds of total impulse to a spacecraft. What this means in simple terms is that the NEXT engine can make a spacecraft go (eventually) very far and very fast."
