NeutronStar Systems UG is developing a disruptive electric propulsion technology that can reduce mission costs for satellite operators by tens of millions of euros, through cheaper propellant and more efficient operation. It calls the solution SUPREME (SUPerconductor-Based Readiness Enhanced Magnetoplasmadynamic Electric Propulsion). It is based on widely-research appliedfield magnetoplasmadynamic (AF-MPD) thrusters and industrially mature high-temperature superconductors.
SUPREME offers the benefits of AF-MPD technology, namely excellent scalability, a wide operational range, and the ability to use alternative propellants, which are more sustainable and considerably cheaper than existing options. The use of superconductors greatly reduces the mass, volume and power consumption of the propulsion system, while simultaneously enabling longer lifetimes and greater performance.
