Russia Tests Plasma Engine Aiming to Halve Mars Travel Time
Russia’s Troitsk Institute (Rosatom) is testing a 300 kW pulsed plasma engine that uses hydrogen and an onboard nuclear reactor to provide continuous thrust, potentially cutting Mars travel from months to about one to two months. Ground tests in a vacuum chamber suggest long operational life, with space deployment hoped for around 2030, though the tech remains unproven in space and faces regulatory and safety hurdles.
