Benchmark Space Systems’ DFAST product line was developed to provide the benefits of reliable, high-precision positioning and control capability with unprecedented safety and affordability.  

This innovative system uses inert, nontoxic powdered fuel that is filled before shipping and remains inert until a pressurization command is triggered on-orbit. The ability to fill, ship, store, and inhibit an assembled & fueled DFAST is “a game changer” for lowering launch manifest and operational costs, improving safety and reliability over alternatives, and providing a path to ISS compatibility.

Additive manufacturing on primary components delivers unbeatable lead time, making this the premier propulsion solution for your next CubeSat mission.
