Lithium MPD thruster cuts fuel 90%

The MPD thruster uses electricity and magnetic fields to launch lithium ions, which means it can deliver strong thrust while using 90% less fuel than regular rockets.
NASA hopes to boost this engine's power even more (up to 4 megawatts) and pair it with a new nuclear reactor system called Space Reactor-1 Freedom, launching as soon as 2028.
Together, these tech upgrades could finally make crewed trips to Mars possible, open up a whole new chapter in space exploration.
