Utilizing a closed-loop fire methodology, Xantus was able to produce precise thrust on demand, validating steady-state thrust across power levels between 0W to 50W, on a world-class test stand configured specifically for measuring millinewton class systems (uniquely small among the breadth of capability at NASA’s electric propulsion division).  ![IMG\_2353-2](https://www.benchmarkspacesystems.com/hs-fs/hubfs/IMG_2353-2.jpg?width=500&height=375&name=IMG_2353-2.jpg)In addition to the current flight unit testing, thrust and impulse data was gathered for promising alternative propellants, which may offer unique advantages for specific missions and regimes. The thrust stand data confirmed that the same specific alloy of stainless steel currently available from the balloon tanks of discarded launch vehicle second-stages, which constitute a sizeable chunk of on-orbit debris, is a viable fuel source for Xantus. Xantus is a critical piece to precision maneuvers and in-space servicing, as well as Benchmark’s hybrid propulsion strategy to support a variety of on-orbit operations by providing complementary technology to existing flight-proven, high-thrust chemical propulsion systems.     Visit our [product page](https://www.benchmarkspacesystems.com/products#slide-3-5) for additional information,

can utilize just about any metal as fuel, with direct thrust data using molybdenum, magnesium, copper, and stainless steel (potentially harvested from existing space debris)* Additional Information:
