SUMMARY: A new ion engine design, under consideration for NASA's Jupiter Icy Moons Orbiter mission, has been successfully tested. This was the first performance test of the Nuclear Electric Xenon Ion System, which will use a nuclear reactor to generate electricity for the spacecraft's ion engine - previous ion engines, like on Deep Space 1 and SMART-1 are solar powered. The new engine operated with 10 times the thrust of Deep Space 1, and should be able to run for 10 years; enough time to visit each of Jupiter's icy moons which are potential candidates for life.
