Xenon-based ion thrusters

Heard in 1 episode across 1 show since Sep 2026

Xenon-based ion thrusters are a highly efficient form of electric spacecraft propulsion that ionize xenon gas to generate thrust. Xenon is the preferred propellant for these systems due to its high atomic mass, low ionization energy, and chemically inert nature, which prevents corrosion of the thruster components. These engines are widely used for deep-space missions, satellite station-keeping, and orbit-raising maneuvers.
