A laboratory prototype of a plasma electric rocket engine based on a magnetic plasma accelerator has been produced by Rosatom scientists, who say it could slash travel time to Mars to one or two months.
Rosatom says that the average power of the engine, operating in pulse-periodic mode, reaches 300kW making it possible to accelerate the spacecraft to much higher speeds than conventional engines.
Alexey Voronov, first deputy director general for science at the Rosatom Research Institute in Troitsk, said: “Currently, a flight to Mars using conventional engines can take almost a year one way, which is dangerous for astronauts due to cosmic radiation and exposure to radiation. Using plasma engines can shorten the mission to 30–60 days, meaning it will be possible to send an astronaut to Mars and back.”
