A method was developed for transfer of lunar soil into and out of process equipment. The Lunar Materials Handling System (LMHS) conveys solids to a process vessel, provides a gas-tight seal, prevents seal contamination, and minimizes wear from abrasive particles. The LMHS increases equipment life and minimizes process losses, thereby increasing overall in-situ resource utilization (ISRU) leverage. The LMHS is based on a seal arrangement by which lunar or Mars regolith can be repeatedly introduced into, and removed from, reaction chambers operating under a wide range of conditions. An integrated LMHS was demonstrated during operation in a one-cubic-meter vacuum chamber using hydrogen reduction as an ISRU process demonstration platform.
