Moscow: Russian scientists at Rosatom have developed a laboratory prototype of a plasma electric rocket engine, marking a major breakthrough in deep-space propulsion technology.

The engine, based on a magnetic plasma accelerator, offers enhanced thrust (at least 6 Newtons) and specific impulse (100 km/s), significantly reducing fuel consumption compared to conventional chemical engines.

Operating at 300 kilowatts in pulsed mode, the engine could cut Mars travel time from nearly a year to just 30-60 days, minimizing astronauts' exposure to cosmic radiation. “The prototype is a crucial step toward developing nuclear-powered 'space tugs' and cost-effective deep-space missions,” said Alexey Voronov, First Deputy Director General for Science at Rosatom's Troitsk Research Institute.

To support testing, Rosatom is building an advanced experimental facility in Troitsk, featuring a 4-meter-diameter, 14-meter-long vacuum chamber with high-efficiency vacuum and heat removal systems to simulate space conditions.

Rosatom continues to spearhead nuclear innovations under Russia's “New Nuclear and Energy Technologies” initiative, driving advancements in space power systems, telescopes, and radiation-testing devices. These developments strengthen Russia's position in deep-space exploration and bolster its technological independence in the global space industry.
