Abstract: Hall thrusters provide efficient space propulsion by electrostatic acceleration of ions. Rotating electron clouds in the thruster overcome the space charge limitations of other methods.

An illustration of the Psyche spacecraft and its asteroid. NASA Less than two years after launch, NASA’s Psyche spacecraft experienced a glitch in its propulsion system that’s now jeopardizing ...

Over time, leftover propellant residue deposited after each firing gradually clogged the narrow inlet pipes of the main thruster. This forced engineers to switch both Voyager 1 and 2 to their ...

According to the NTSB report, 'damage was found on the engine's inlet cowl liner, thrust reverser, fan blades, and guide vanes' as a result of the wheel and tire being destroyed in the landing.

"Metal fragments from the wheel assembly appear to have been ingested by the number one (left) engine and damage was found on the engine's inlet cowl liner, thrust reverser, fan blades, and guide ...

Abstract: A 2-D axial-azimuthal model of an annular Hall thruster discharge is developed. We use a hybrid fluid-particle-in-cell (PIC) treatment to model a Xe-propellant Hall thruster. Using a PIC ...

"The thruster gets weaker and weaker and allows less propulsion." That propulsion is vital. Even a slight misalignment of the antennas could sever contact between the spacecraft and Earth ...
