Plasma Rocket Engine
From Wikipedia: "A plasma propulsion engine is a type of Ion thruster which uses plasma in some or all parts of the thrust generation process. Though far less powerful than conventional rocket engines, plasma engines are able to operate at higher efficiencies and for longer periods of time. Plasma engines are better suited for long-distance Interplanetary space travel missions.
Plasma propulsion engines were first developed by the Soviet Union during 1963-1965 to propel spacecraft to Mars. In more recent years, many agencies have developed several forms of plasma fueled engines, including the European Space Agency, Iranian Space Agency and Australian National University, which have co-developed a more advanced type described as a double layer thruster. However, this form of plasma engine is only one of many types."
