B125 Propulsion System

Benchmark Space Systems’ B125 delivers a non-toxic (‘green’), high thrust propulsion system to the small satellite market. Our innovations address challenges with alternative systems in this class:  lead time, launch safety, and power consumption.

Our proprietary on-demand pressurization technology and non-toxic propellants will ease your launch manifest and expand your on-orbit capabilities. Additionally, Benchmark Space’s patent pending micromixing technique eliminates the need for catalyst beds, a high cost, long-lead component used in other chemical propulsion systems.

With in-house components designed for additive manufacturing, Benchmark offers an industry-best performance and value.
