This manner of operation means that an ion thruster and a small mass of fuel can theoretically create a much larger delta-V than chemical rockets, perfect for long-range space missions to Mars and ...

The AEPS is a solar electric propulsion system that uses xenon as its propellant, much like existing ion engines. Where it differs is in the power output, which should allow it to work as the ...

Inspired by NASA aerospace engineering, this project features a plasma thruster, designed to maximize efficiency and increase ...

P redicting the lifetime of an electric ion thruster is notoriously difficult. You have to account for the chamber wall effects, which are not present in space environments. Researchers within ...

But to travel from low-Earth orbit (LEO) to farther orbits—or even the Moon—requires a different kind of ion thruster capable ...

Unlike most interplanetary probes, Dawn is not propelled by a chemical rocket engine, but by a solar-electric ion propulsion system, particularly suitable for long-distance flights. This innovative ...

Hollow cathodes are used as part of both Hall effect and gridded ion thrusters, which are some of the most common forms of electric propulsion in use today. The operation of hollow cathodes, despite ...

These systems are characterized by the propellant used and emission mode of the ion beam. The most common of these, field emission electric propulsion (FEEP), utilize liquid metals as its ion source ...

Dr. King is an experimentalist interested in studying electric space propulsion systems, including Hall-effect thrusters, ion engines, and arcjets. By utilizing strong electromagnetic forces to ...
