The agency has also been testing a more advanced ion engine, called NASA’s Evolutionary Xenon Thruster (NEXT), which generates times as much thrust as an NSTAR engine. The majority of NASA’s research into Hall thrusters is currently focused on the Advanced Electric Propulsion System, or AEPS.
This is a solar electric propulsion system which encompasses the power generation and conditioning equipment, as well as a 14 kW SPT thruster known as HERMeS, or the Hall Effect Rocket with Magnetic Shielding.

TAPPER; https. The basic principle is to create and accelerate massive electric charges like ions (hence the term ion propulsion), to ejection speeds much higher than chemical propulsion.
Whereas in chemical propulsion the main difficulty comes from achieving large thermal energy, here the difficulty comes from disposing, in space, of a large electric power. Ion Propulsion Ion propulsion is a method of propulsion that uses electrical rather than chemical forces to generate thrust for a spacecraft.
Although less powerful than chemical engines, ion propulsion engines are more efficient and can be used continuously for long periods, making them ideal for deep space missions.
The concept of ion propulsion has existed for many years, but only recently. 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 use a magnetic field to limit the electrons' axial motion and then use them to ionize propellant, efficiently accelerate the ions to produce thrust, and neutralize the ions in the -effect thrusters (based on the discovery.
Because of the low thrust, ion thrusters are incapable of reaching orbit independently ; 7 The Disadvantage of Ion Propulsion 8 Systems Ion Thruster.
