Plasma propulsion is a cutting-edge technology used in spacecraft to generate thrust. It works by heating a gas until it becomes plasma, a state of matter where electrons are separated from atoms. This plasma is then expelled at high speeds, pushing the spacecraft in the opposite direction, much like how a rocket works. This method is more efficient than traditional chemical propulsion, allowing for longer missions and less fuel consumption. One popular type of plasma propulsion is the ion thruster. These thrusters use electric fields to accelerate ions, creating a steady and powerful stream of plasma. This technology has been successfully used in missions like Dawn, which explored the asteroid belt, showcasing the potential of plasma propulsion for deep space exploration.
