Hybrid Propulsion Systems
Benchmark Space Systems
With hybrid vehicle sales at an all-time high on Earth, Benchmark Space Systems has announced a definitive agreement to acquire Alameda Applied Sciences Corporation’s (AASC) electric propulsion technologies to help power hybrid spacecraft designed to ultimately run on in-space resources and repurposed space debris. Benchmark’s turnkey hybrid chemical + electric propulsion systems will leverage the high thrust capabilities of its non-toxic chemical Halcyon HTP propulsion systems and the precision maneuverability of its Xantus metal plasma thrusters (MPTs), a core part of the newly named electric propulsion technology acquired from AASC.
The hybrid propulsion solution will deliver unprecedented operational versatility across cubesats, microsats, ESPAs, and OTVs by leveraging Benchmark’s DEVO propulsion controller with SmartAIM ™ Guidance, Navigation and Control (GNC) software aboard the flight-proven Halcyon system and the new Xantus EP metal plasma thrusters. The bundled solution will efficiently and effectively support a broad range of in-space applications including speedy, ROI-boosting rapid insertion; satellite station-keeping; precision pointing; controlled de-orbiting; collision avoidance; and rendezvous and proximity operations (RPO).
The Xantus metal plasma thrusters, which can single-handedly address most cubesat missions, will be an integral tool for microsat mission optimization with high-efficiency ‘cruise control’ functionality for station keeping, mission extension, and ultra-precise pointing operations.
Benchmark’s technology and product roadmap leads to a prominent role in future On-Orbit Servicing, Assembly and Manufacturing (OSAM) operations, where AASC’s MPT technology will support in-space proximity and docking operations. The Halcyon + Xantus hybrid packages are engineered to ultimately incorporate in-space resource utilization (ISRU) techniques to enable a sustainable space ecosystem. Benchmark’s hydrogen-peroxide (HTP) systems are designed to one day refuel on orbit with propellant created from space ice and water, while the AASC-developed MPTs will replenish in flight with metal harvested from unwanted and problematic orbital space debris – enabled by a set of breakthrough capabilities being demonstrated in space by fellow OSAM pioneers.
Part of Benchmark’s electric propulsion strategy, the AASC MPT acquisition follows an in-depth global evaluation of leading EP technology specialists. AASC’s metal plasma thruster technology is extremely robust and well packaged, nearing production phase, integral to NASA’s Artemis mission, and scheduled to earn flight heritage during a US Space Force demonstration mission (RROCI) this year aboard an Orion Space Solutions satellite.
Benchmark announced earlier this year that it has tripled its U.S. production capacity and doubled U.S. manufacturing and technical staff to meet big demand for its Starling and Halcyon chemical propulsion systems. The company has scaled up to build more than 150 systems over an eighteen-month period to enable in-space mobility and maneuverability aboard a spectrum of spacecraft integral to the new space economy and a broad range of LEO, GEO, and cislunar missions. Benchmark is also close to initiating production at its new UK manufacturing and testing facility in partnership with Satellite Applications Catapult at the Westcott Innovation Centre in Aylesbury, England, home of the UK’s propulsion research and development.
Benchmark’s scalable, launch vehicle agnostic propulsion products and services suite support a broad spectrum of spacecraft – from 3U cubesats through ESPA-class (3-500kg) satellites, lunar landers, spent launcher stages, and orbital transfer vehicles (OTVs), which will enable a broad range of in-space services and capabilities supporting the space economy and ecosystem.
