Bulk Metallic Glass Gear Project

NASA Bulk Metallic Glass Gear (BMGG) project develops strong, elastic, low-temperature gear technologies that can operate without conventional lubrication in extreme environments. The project supports mechanisms for lunar, Martian, and icy-world missions where cryogenic temperatures and abrasive conditions challenge conventional spacecraft hardware.
