FEEP (Field Emission Electric Propulsion)

Field Emission Electric Propulsion (FEEP) is an advanced spacecraft propulsion technology that uses electric fields to accelerate charged particles, creating thrust. Unlike traditional rockets that burn fuel, FEEP systems ionize a propellant, such as cesium or indium, and then use electric fields to draw and expel these ions at high speeds. This method offers high efficiency and precise control, making it suitable for small satellites and deep-space missions. By using less fuel, FEEP allows spacecraft to operate longer and more sustainably in the harsh environment of space.
