Sustainable execution of prolonged space missions depends upon the utilization of local resources and waste products from manned spacecraft and planetary bases. Successful in-situ resource utilization (ISRU) will require component technologies which are optimal in size, weight, volume and power efficiency. ISRU gives more flexibility to extravehicular activities by incorporating portable life support systems, improves mobility by providing fuel for rovers and increases mission longevity by producing fuel for return missions.
