VXB Aerospace

VXB Aerospace is an Australian propulsion startup based in Canberra developing AI-optimized Hall-effect electric thrusters for small and medium satellites. The company's flagship Zephyr-M thruster uses machine learning to optimize the thruster design geometry, magnetic field topology, and operational parameters — enabling claimed performance gains of dramatically lower propellant consumption (reducing fuel costs approximately 100× compared to conventional thrusters at comparable thrust levels) and 5× lower unit manufacturing costs by simplifying the component design. Hall-effect thrusters (HETs) work by ionizing a propellant (typically xenon or krypton) and accelerating the ions with an electric field, achieving specific impulse values of 1,000–3,000 seconds compared to 200-300 seconds for chemical thrusters — making them highly efficient for station-keeping and orbit-raising over the multi-year lifetimes of LEO and GEO satellites. VXB Aerospace raised AUD $1.2M in seed funding with six customer letters of intent, indicating early market validation for the technology. Australia's growing space industry, supported by the Australian Space Agency (established 2018) and the Australian Space Industry Growth Centre, provides a supportive domestic environment for space propulsion startups serving the global smallsat market.
