NEXT = NASA Evolutionary Xenon Thruster
Quoth the wiki;
"The NEXT engine is a type of solar electric propulsion in which thruster systems use the electricity generated by the spacecraft's solar panel to accelerate the xenon propellant to speeds of up to 90,000 mph (145,000 km/h). NEXT can produce 6.9 kW thruster power and 236 Nm thrust. It can be throttled down to 0.5 kW power, and has a specific impulse of 4190 seconds (compared to 3120 for NSTAR). The NEXT thruster has demonstrated a total impulse of 17 MN·s; which is the highest total impulse ever demonstrated by an ion thruster.
