Yet it faces an invisible bombardment more relentless than any terrestrial storm, a constant rain of micrometeoroids, tiny fragments of rock and metal traveling at speeds up to 70 kilometers per second. As NASA’s Artemis program prepares to establish a permanent lunar base, understanding this silent threat has become critical to keeping future astronauts safe.
