Psyche’s Hall Thruster
The photo on the left captures an operating electric Hall thruster identical to those that will propel NASA's Psyche spacecraft. The xenon plasma emits a blue glow as the thruster operates. The photo on the right shows a similar non-operating Hall thruster. The photo on the left was taken at NASA's Jet Propulsion Laboratory in Southern California; the photo on the right was taken at NASA's Glenn Research Center. Psyche's Hall thrusters will be the first to be used beyond lunar orbit, demonstrating that they could play a role in supporting future missions to deep space.
