Busek BHT-600 Hall thruster

Busek's BHT-600 is a mature 600 W-class Hall-effect propulsion system for ESPA-class spacecraft, available with direct or gimballed mounting and designed for xenon, krypton, or iodine. Busek specifies a 300-800 W throttle range, 39 mN nominal thrust, and 1,300-1,500 s nominal specific impulse; NASA records a first flight-system shipment in 2021 and a 7,000-hour ground test, supporting an active product identity without asserting a specific vehicle-family edge.
