The new plasma thruster will slash the cost of building massive satellite constellations.
Specialists from the Moscow Aviation Institute and the Moscow Institute of Physics and Technology developed the engine
Krypton is 5–10x less expensive than xenon and available in much larger volumes
Designed for at least 7 years of service life in orbit, with 7,500+ hours of total thrust and multiple restart capability
The shift to krypton was driven by the need for affordable propulsion as Russia scales up multi‑satellite projects like the Sfera communication system
