New Ion Engine Under Test

It’s a long old flight to get to anything of interest once you leave planet Earth behind. So for lengthy missions, you’ll need a compact and fuel efficient power-source, which is why NASA are testing a new breed of ion thruster. The NASA Evolutionary Xenon Thruster, or NEXT, uses xenon gas and solar power to provide its push, which is 2.5 times greater than previous designs could muster.
