Engineers at NASA's Marshall Space Flight Center have completed environmental and physical testing on a new small satellite designed to use a single dual-mode propulsion system for multiple types of orbital maneuvering, replacing the traditional need for separate, bulky propulsion systems. The tests are a precursor to the CubeSat's upcoming launch. The project aims to make spacecraft propulsion safer and more efficient by reducing reliance on volatile fuels, part of NASA's broader push to miniaturize and simplify small-satellite technology.
