Magnetoplasmadynamic thruster

A Magnetoplasmadynamic (MPD) thruster is a type of electric propulsion device used for spacecraft. It works by passing an electrical current through a propellant, usually a noble gas like argon, creating a plasma—a super-hot, ionized gas. Powerful magnetic and electric fields then accelerate this plasma at high speeds out of the engine, producing thrust. This method allows for efficient, high-velocity propulsion, enabling spacecraft to travel longer distances or carry heavier payloads more efficiently than traditional chemical rockets. MPD thrusters are promising for future space missions requiring rapid or extensive travel.
