6 kW Hall thruster in operation at the NASA Jet Propulsion Laboratory. Spacecraft electric propulsion (or just electric propulsion) is a type of spacecraft propulsion technique that uses electrostatic or electromagnetic fields to accelerate mass to high speed and thus generating thrust to modify the velocity of a spacecraft in orbit.

An MPD thruster was tested on board the Japanese Space Flyer Unit as part of EPEX (Electric Propulsion Experiment) that was launched March 18, 1995 and retrieved by space shuttle mission STS-72 January 20, 1996. To date, it is the only operational MPD thruster to have flown in space as a propulsion system.
6 kW Hall thruster in operation at the NASA Jet Propulsion Laboratory. In spacecraft propulsion, a Hall-effect thruster (HET) is a type of ion thruster in which the propellant is accelerated by an electric field. Hall-effect thrusters (based on the discovery by Edwin Hall) are sometimes referred to as Hall thrusters or Hall-current thrusters.
Plasmadynamics and Electric Propulsion Laboratory (PEPL) is a University of Michigan laboratory facility for electric propulsion and plasma application research. The primary goals of PEPL are to increase efficiency of electric propulsion systems, understand integration issues of plasma thrusters with spacecraft, and to identify non-propulsion applications of electric propulsion technology.
This was the first use of electric propulsion as the interplanetary propulsion system on a science mission. [25] Based on the NASA design criteria, Hughes Research Labs developed the Xenon Ion Propulsion System (XIPS) for performing station keeping on geosynchronous satellites . [ 99 ]
The NEXT thruster has demonstrated, in ground tests, a total impulse of 17 MN·s; which as of 2010 was the highest total impulse ever demonstrated by an ion thruster. [2] A beam extraction area 1.6 times that of NSTAR allows higher thruster input power while maintaining low voltages and ion current densities, thus maintaining thruster longevity.
High-power solar electric propulsion is a key technology that has been prioritized because of its significant exploration benefits in cis-lunar space and crewed missions to Mars. [ 1 ] The AEPS Hall thruster system was originally developed since 2015 by NASA Glenn Research Center and the Jet Propulsion Laboratory to be used on the now canceled ...
The machinery to do this is complex, but research has developed methods for their use in propulsion systems, and some have been tested in a laboratory. [ 68 ] Here, nuclear propulsion moreso refers to the source of propulsion being nuclear, instead of a nuclear electric rocket where a nuclear reactor would provide power (instead of solar panels ...
