Busek develops Hall-effect thrusters designed to balance high specific impulse with excellent thrust-to-power.
Busek developed and deployed the first electrospray thruster in space.
LunaH-Map’s thruster is a BIT-3 from Busek that uses iodine as propellant.
LunaH-Map’s primary propulsion system is an electric thruster called BIT-3 manufactured by Busek that uses solid iodine as propellant.
The OneWeb satellites launched in December and January provide flight heritage for Busek’s BHT-350 solar electric propulsion systems.
Busek possesses vacuum facilities and diagnostic equipment to both build thrusters in high quantities and test them.
Busek is operating at a production rate of over 20 thrusters per month with 100 percent hot-fire acceptance testing.
Busek completed on-orbit commissioning of its BHT-350 Hall-effect thrusters on 80 OneWeb satellites launched in December and January on SpaceX Falcon 9 rockets, reported on 2023-02-06.
Busek is producing 6-kilowatt Hall-effect thrusters for the NASA lunar Gateway Power and Propulsion Element being built by Maxar Technologies.
LunaH-Map is equipped with a BIT-3 ion thruster from Busek that uses solid iodine fuel.
OneWeb Satellites pivoted from electric propulsion systems imported from Russia’s Fakel to thrusters supplied by U.S.-based Busek Co.
Busek is producing 6-kilowatt Hall-effect thrusters for the NASA lunar Gateway Power and Propulsion Element being built by Maxar Technologies.
Busek is supplying BHT-350 Hall thrusters to Florida-based Airbus OneWeb Satellites.
Busek’s product line includes miniature electrospray thrusters based on technology developed with NASA’s Jet Propulsion Laboratory for the European Space Agency’s LISA Pathfinder mission launched in 2015.
Busek acquired a 1,022-square-meter facility this summer, bringing the company’s total offices, laboratory, and manufacturing space to nearly 4,645 square meters.
Maxar Technologies and Busek Co. completed an end-to-end hot fire test campaign validating all major elements of a 6 kW solar electric propulsion subsystem designed for the Power and Propulsion Element.
The PPE thruster system includes Maxar-built high-power control electronics PPU-6000, a Moog-provided xenon feed system, and four Busek-built BHT-6000 Hall effect thrusters.
The Busek BHT-6000 thrusters tested at 6 kW will later be combined with other higher-power thrusters to complete the PPE’s 50 kW electric propulsion system.
Busek’s BHT-6000 Hall effect thruster demonstrated stable operation at 6 kW and 600 V.
The integrated 6 kW SEP system tested for PPE is 30% more powerful than any SEP system previously flown by Maxar or Busek.
