The ESA field emission electric propulsion (FEEP) ionization principle, FEEP emitter, and program status are described. The FEEP is a viable propulsive concept for north/south stationkeeping of geostationary satellites and for drag compensation of low Earth orbit satellites. The ion optics studies and investigation of the ion-emitting region helped to define the beam boundaries and to establish criteria for the design of the acceleration electrode. A solid slit emitter was developed and clustering verification demonstrated in a 1200 hr endurance test. Thrust level can be matched exactly to available electric power. A plasma bridge neutralizer developed for cesium bombardment is to be used. A thruster dedicated power supply module and central power-control module are being developed. Industrialization of the FEEP is underway.
