Plasma engines are emerging as the next frontier in deep-space propulsion

Plasma engines, which use magnetic fields to accelerate superheated charged particles instead of conventional fuel, are rapidly advancing as the key technology to dramatically reduce deep-space travel times. NASA, Russia's Rosatom, and China are racing to develop these systems that could cut Mars trips from eight months to just 45-60 days, with Russia claiming their prototype achieves breakthrough speeds of 100 kilometers per second.
