The 3D-printed titanium scoop of the Cold Operable Lunar Deployable Arm (COLDArm) robotic arm system is poised above a test bed filled with material to simulate lunar regolith (broken rocks and dust) at NASA's Jet Propulsion Laboratory in Southern California. COLDArm can function in temperatures as cold as minus 280 degrees Fahrenheit (minus 173 degrees Celsius). Robotics engineer David E. Newill-Smith looks on during testing in September 2022. COLDArm is designed to go on a Moon lander and operate during lunar night, a period that lasts about 14 Earth days. Frigid temperatures during lunar n…
