The CirculaREEconomy project will commence on 1 August 2025 to produce high-purity, separated rare earth oxides.

In this study, the numerical simulations are used to simulate the discharge process of a 10-cm dual-stage 4-grid (DS4G) radiofrequency (RF) ion thruster, and the effects of RF coil turns, and ...

A comprehensive 0-D model of the plasma discharge in magnetic ring-cusp ion thrusters was previously developed. The model utilizes conservation of particles into and out of the ion thruster and ...

The Defense Advanced Research Projects Agency (DARPA) has announced a new, innovative program, the XQ-73 Series Hybrid Electric Propulsion AiRcraft Demonstration (SHEPARD).

The spacecraft host several technology demonstrators, including autonomous mission tasking software, algorithms that enable formation flying within a few kilometers using an ion propulsion system ...

A comprehensive 0-D model of the plasma discharge in magnetic ring-cusp ion thrusters was previously developed. The model utilizes conservation of particles into and out of the ion thruster and ...

Furthermore, the mutual interference of active high-frequency components—such as the radio-frequency generator typically used in RF ion thrusters—and satellite components must be taken into account in ...

A Tohoku University researcher has increased the performance of a high-power electrodeless plasma thruster, moving us one step closer to deeper explorations into space. y, several space missions have ...

The method may further include generating an RF current using the charge image circuit and generating a direct current from the RF current using an RF-to-DC rectifier circuit. Avalanche Energy ...
