Nature : Although most of the craters on the Moon’s surface formed millions of years ago, at least 222 new ones have appeared since 2009. The freshly formed depressions, which were identified by comparing images taken by NASA’s Lunar Reconnaissance Orbiter with those taken decades ago by Apollo astronauts, are distributed across the lunar surface and range in size between 2 m and 43 m in diameter. Because the number of fresh craters is much larger than scientists had expected, researchers may need to rethink estimates of the lunar surface’s age and the design of any future lunar installations.
