Let Parabilis design and deliver the optimal propulsion system for your mission.

Our engineers have the technical breadth, depth, and experience to optimize propulsion systems for satellites from Cubes to ESPA Grande. Every mission is unique, and so is every customer—we’re passionate about finding the right solution for you. Whether you need a bolt-on propulsion module or integration with your existing bus structure, we tailor our designs using a wide range of in-space propulsion technologies, including solar electric, liquid monopropellant, bipropellant, and hybrid solid-liquid propulsion systems.

We begin with your mission parameters—orbit(s), trajectory changes, lifetime, launch vehicle, satellite mass, volume, and interfaces—and trade key factors such as component TRL, mass, volume, ΔV, thrust, lead time, integration schedule, and cost. While Isp is a key metric, we know that mass efficiency, volume efficiency, lead times, and integration risk often matter more in the SmallSat market. Our experienced engineers expertly manage the technical and schedule risks that arise when tailoring designs for new missions. Parabilis sources components from across the industry without bias, ensuring we deliver the best solution for your needs.

We aim to be your propulsion partner—from design to procurement, integration, testing, delivery, and post-delivery support. We develop detailed CAD models and collaborate with your engineering teams to ensure propulsion systems are optimized for both performance and assembly. Our facilities include a Class 10,000 cleanroom for integration and test, in-house welding and inspection, and a dedicated propulsion test facility for testing up to 5,000 lbf of thrust, permitted for a wide range of rocket propellants.

Parabilis is a non-traditional propulsion company—by FAR definition and by nature: agile, innovative, and open. Our lean structure and commitment to low-complexity high-performance designs naturally yield low cost and short lead time. At Parabilis, we are redefining how propulsion solutions are delivered.
