NASA, in collaboration with the Jet Propulsion Laboratory (JPL), successfully tested a 120-kilowatt lithium-fed magnetoplasmadynamic (MPD) thruster on May 08, 2026. The advanced propulsion technology uses ionized lithium plasma accelerated through magnetic fields to produce electromagnetic thrust. The system operates using Nuclear Electric Propulsion (NEP), where a compact nuclear reactor powers the thrusters instead of solar energy. This innovation is significant for future deep-space exploration and crewed Mars missions, which may require power outputs between 2 and 4 megawatts. The successful test represents a major milestone in high-power space propulsion technology for long-duration interplanetary travel.
