In the long vigil humanity has kept over the moon, moments of genuine surprise are rare — yet in late September 2026, NASA's lunar orbiter delivered one. A massive, freshly formed crater appeared in orbital imagery, bearing the sharp edges and undisturbed character of a very recent impact, prompting scientists to call it a once-in-a-lifetime find. The discovery arrives at a consequential moment, as space agencies worldwide press forward with plans for permanent human presence on the lunar surface, making the question of where rocks fall from the sky no longer merely academic.
