ionijärjestelmät
Ionijärjestelmät, also known as ion propulsion systems, are a type of electric propulsion used for spacecraft. Unlike traditional chemical rockets, which expel mass to generate thrust, ion thrusters use electric power to accelerate ions to high velocities. This results in a much higher specific impulse, or efficiency, compared to chemical rockets, making them ideal for long-duration missions.
The basic principle behind ion thrusters is the acceleration of ions using electric fields. Ions are created
Ion thrusters have been successfully used in space missions, such as NASA's Dawn mission to the asteroid
There are several types of ion thrusters, including gridded ion thrusters, Hall-effect thrusters, and pulsed plasma
