An ion thruster, ion drive, or ion engine is a form of electric propulsion used for spacecraft propulsion. An ion thruster creates a cloud of positive ions from a neutral gas by ionizing it to extract some electrons from its atoms. The ions are then accelerated using electricity to create thrust.
Related to the electrostatic ion production method is the need for a cathode and power supply requirements. Electron bombardment thrusters require at the least, power supplies to the cathode, anode and chamber. RF and microwave types require an additional power supply to the rf generator, but no anode or cathode power supplies.
Current EHD thrusters are far less efficient than conventional engines. [15] An MIT researcher noted that ion thrusters have the potential to be far more efficient than conventional jet engines. [16] Unlike pure ion thruster rockets, the electrohydrodynamic principle does not apply in the vacuum of space. [17]
An electrostatic pinwheel, or corona spinner, attached to a small Wimshurst machine (electrostatic generator) is shown stationary and rotating. Ion wind, ionic wind, corona wind or electric wind is the airflow of charged particles induced by electrostatic forces linked to corona discharge arising at the tips of some sharp conductors (such as points or blades) subjected to high voltage relative ...
This type of thruster can accelerate a large number of different liquid metals or alloys. The best performance (in terms of thrust efficiency and power-to-thrust ratio) can be obtained using high atomic weight alkali metals, such as cesium ( Cs , 133 amu) and rubidium ( Rb , 85.5 amu).

The NASA Solar Technology Application Readiness (NSTAR) is a type of spacecraft ion thruster called electrostatic ion thruster. [1] [2] It is a highly efficient low-thrust spacecraft propulsion running on electrical power generated by solar arrays. It uses high-voltage electrodes (including two fine grids) to accelerate ions with electrostatic ...
Such a thruster often generates the source plasma using radio frequency or microwave energy, using an external antenna. This fact, combined with the absence of hollow cathodes (which are sensitive to all but noble gases ), allows the possibility of using this thruster on a variety of propellants, from argon to carbon dioxide air mixtures to ...
