Quick Facts
About Benchmark Space Systems
Benchmark Space Systems is a Vermont-based propulsion company developing high-performance green propulsion systems for small satellites. Founded in 2017 in Burlington, the company manufactures the HALCYON thruster family using AF-M315E (also marketed as ASCENT) — a high-performance ionic liquid propellant developed by the Air Force that delivers 12% higher specific impulse than hydrazine while being far less toxic, enabling satellites to be fueled and handled without SCAPE suits.
Benchmark's thrusters serve CubeSats from 6U through ESPA-class satellites and have flown on multiple commercial and government missions. The company has raised funding from strategic investors in the satellite industry and is scaling production to support the growing smallsat constellation market that requires reliable, high-Isp propulsion for long-duration operations and orbital maneuvers.
