Busek

Busek Company, founded in 1985 and based in Natick, Massachusetts, specializes in the development of high-performance electric propulsion systems and spacecraft components. The company focuses on several key technologies including Hall thrusters, electrospray thrusters, RF ion thrusters, and green monopropellant thrusters utilizing a novel ASCENT formulation. Busek distinguishes itself through a commitment to efficiency and performance, offering solutions designed for a wide range of spacecraft missions.

Busek has established a significant flight heritage, notably building the first flight-qualified US Hall thruster launched in 2006 on the TacSat-2 mission, and continues to supply propulsion systems for ongoing space endeavors. The company is currently a supplier to NASA’s Artemis program, providing thrusters for missions aimed at lunar exploration. Beyond Hall effect technology, Busek has pioneered electrospray thrusters demonstrated on the LISA Pathfinder mission, and is developing iodine-fueled RF ion thrusters for upcoming deep-space CubeSat missions.

The company’s green monopropellant thruster, fueled by ASCENT, represents a further innovation, offering improved performance and reduced toxicity compared to traditional hydrazine-based systems. Busek’s diverse portfolio and thirty-five years of experience position it as a key player in the growing electric propulsion market, catering to both established space programs and the burgeoning small satellite industry.
