American technological superiority/National achievement Future human exploration of Mars

NASA successfully tested a powerful lithium-fed electromagnetic thruster at its Jet Propulsion Laboratory, achieving power levels up to 120 kilowatts. This prototype, which is a magnetoplasmadynamic (MPD) thruster, represents a significant step toward electric propulsion systems capable of supporting future human missions to Mars. The team plans to continue testing to address scaling challenges, aiming for power levels up to 1 megawatt.
