Bulk Metallic Glass Gears (BMGG)

Completed Technology Project

Project Introduction

Bulk Metallic Glass Gears
With NASA's bulk metallic glass alloys we can accomplish more science on icy body missions, like those to Europa, where temperatures are regularly more than twice as cold as ever recorded on earth. Spacecraft mechanisms, specifically gearboxes made from these materials, can operate without power consuming heaters allowing that power to be used, instead, for more instruments or extending the life of the mission.
