Busek's BHT-6000 is a 2-6 kW dual-mode Hall-effect thruster for high-power all-electric orbit raising, station keeping, and de-orbit. Busek documents xenon, krypton, and iodine operation, 320 mN at 5 kW in high-thrust mode, 288 mN at 6 kW in high-impulse mode, and 2,029/2,600 s specific impulse. Busek identifies a four-thruster BHT-6000 cluster with two NASA AEPS thrusters for NASA's Power and Propulsion Element and HALO Lunar Gateway mission, while this record does not invent a separate vehicle-family edge.
