Home Andrew Kennett (left) watches as Dominic Aldi (right) uses liquid nitrogen to cool a motor integrated bulk metallic glass gearbox prior to shock testing it. The motor and gearbox are inside the frosty metal “bucket” that contains the liquid nitrogen. The tooling, including the “bucket” is designed to be mounted both vertically (shown) and horizontally on the cube for testing the motor and gearbox in three orientations.

The motor and gearbox are mounted for testing in one of two horizontal orientations. Frost forms on the surface of the “bucket” when liquid nitrogen is used to cool the hardware to the test temperature of -279 degrees Fahrenheit (-173 degrees Celsius). (NASA/JPL-Caltech)
