Rubicon Space Systems

The Leader in Development and Infusion of

ASCENT-based Technology

Rubicon Space Systems is a committed champion and partner in creating a more verdant space economy. We are a developer and provider of in-space propulsion systems and thrusters that use the low-toxicity “green” and safe Advanced Space Craft Energetic Non-Toxic propellant (ASCENT), also known as AF-M315E. It is no longer a choice between “going green” or high performance. Our thruster technology offers both.

Rubicon Space Systems has more than 30 years of combined experience in developing green propulsion technologies and thousands of hours of thruster testing experience. Our team leads the world in the development and infusion of ASCENT-based propulsion, and we are ready to support your spacecraft mobility needs.


0.1N Thruster

Rubicon Space Systems has developed a line of ASCENT thrusters for small spacecraft. Our 0.1N thruster is flying on NASA’s Lunar Flashlight Propulsion System.

Sprite Propulsion System

Our self-contained modules are designed to operate in single or multi-module mode to add propulsive capability to a spacecraft. The Sprite Propulsion System is a plug-and-play system ideal for delta-V, momentum management, collision-avoidance, and de-orbiting a cubesat or smallsat.

Thrusters & Propulsion Systems

Our goal is to provide fully realized propulsion system solutions to the spacecraft integrator at a cost-point that makes it an easy decision to “go green”.

We will also work collaboratively with our customers to provide customized solutions if necessary.

We work with NASA and AFRL to produce cutting-edge chemical and chemical-electric (aka. Dual-Mode) propulsion technology.
