Nuclear Electric Propulsion

An architecture that pairs a space nuclear reactor with electric thrusters: the reactor generates electricity, which drives ion or Hall thrusters. Unlike solar-electric propulsion it is independent of distance from the Sun, making it a candidate for crewed missions to Mars and the outer Solar System. No nuclear-electric system has yet flown; it remains a design and technology-development goal.
