A CubeSat-scale ISRU reduces costs by significantly reducing the mass of a mission, enabling lower cost sample return missions. Core technologies being developed involve miniaturization and design of miniature compressors and expanders for oxygen and hydrogen handling and water collection and distillation processes in micro-gravity.
An electrolyzer uses electrical current to separate liquid water into hydrogen and oxygen gases. The μISRU uses a Polymer Electrolyte Membrane (PEM) electrolyzer, which is compact, lightweight, and works at lower temperatures than those using other electrolysis methods (see Figure 3-5). The electrolyzer splits water into oxygen and hydrogen and draws them to separate sides of the system, automatically separating the gases. From here the gases are delivered to their respective liquification loops for further processing.
The references to ISRU seem to have been removed as of early 2023. Thus marking as Dormant in the context of this database. Company pivoted to propulsion solutions.
