Russian Researchers Develop Plasma Engine for Mars Missions, Potentially Ready by 2030
Russian researchers at Rosatom's Troitsk Institute are developing a plasma propulsion system aimed at reducing travel time to Mars to one or two months, with a potential readiness for space missions by 2030. The engine, which utilizes electromagnetic fields to accelerate hydrogen particles at speeds of up to 100 kilometers per second, is currently undergoing ground trials and is designed to operate in low-Earth orbit, powered by a nuclear reactor. Successful testing and funding will determine its deployment timeline.

Russian scientists at Rosatom's Troitsk Institute are testing a plasma propulsion system designed to reduce Mars travel time to one or two months. Currently in ground trials, the engine could be space-ready by 2030.
This system uses electromagnetic fields to accelerate hydrogen particles, achieving speeds of up to 100 kilometers per second, significantly faster than conventional chemical rockets. It operates in a pulse-periodic mode at 300 kilowatts and has demonstrated a service life of 2,400 hours, sufficient for a complete Mars mission.
The plasma engine will not launch from Earth but will activate once in low-Earth orbit, where it may also serve as a space tug. The design incorporates a nuclear reactor for power and highlights hydrogen's benefits for acceleration and potential in-situ refueling. While promising, the engine's deployment timeline relies on successful testing and funding, with a flight-ready version anticipated by 2030.
