Extreme Lunar Conditions Need an Extreme Test Rig

When people eventually head to the Moon for long-term exploration and habitation, they'll need equipment and habitats made of well-tested materials. That's where NASA's Lunar Environment Test Rig (LESTR) comes in handy. It simulates extreme cold lunar night conditions right here in a NASA Glenn lab, testing equipment in temperatures ranging from 40K to 125K (-233 C to -148 C) in a vacuum.
