Rubicon’s line of advanced, high-performance thrusters delivers unprecedented performance with true monopropellant simplicity. By harnessing ASCENT (AF-M315E) – a safe, long-term-storable propellant jointly developed by AFRL and NASA – each thruster eliminates the handling risks and system complexity of traditional bipropellant engines.
Our portfolio spans the flight-proven 0.1N thruster, the versatile 1N and 5N thrusters, and the large 110N thruster. Each thruster was meticulously design to minimize pre-heating power requirements, and maximize the operational envelope. Backed by a team with over 35 years of combined propulsion experience and ongoing support from NASA, AFRL and MDA, Rubicon’s ASCENT thrusters’ power smallsat and large spacecraft missions alike.
