What to know about NASA Technological Innovation

NASA's Lunar Environment Test Rig (LESTR) is being used to simulate the extreme cold and vacuum of the moon to test materials for future exploration. The rig allows researchers to evaluate shape memory alloys and other components without the need for liquid cryogens, benefiting both Artemis lunar missions and future Mars voyages.

What happened

Extreme Lunar conditions need an extreme test rig Gaby Clark Scientific Editor Andrew Zinin Lead Editor When people eventually head to the moon for long-term exploration and habitation, they'll need equipment and spacesuits made of well-tested materials.

Why it matters

That's where NASA's Lunar Environment Test Rig (LESTR) comes in handy.

Common ground

It simulates extreme cold lunar night conditions right here on Earth in a NASA Glenn lab, testing lunar-bound materials in temperatures ranging from 40 K to 125 K (-233 C to -148 C) in a vacuum.
