Scientists analyzing data from NASA's Lunar Reconnaissance Orbiter have discovered a massive impact crater on the Moon measuring approximately 225 meters in diameter and 43 meters deep. Officially named McGetchin, the steep-sided crater was formed by a high-speed asteroid or comet impact between April and May 2024. The event went undetected in real time but was uncovered during routine comparative image analysis. Researchers report that such large-scale impacts occur roughly once every century, serving as a rare natural laboratory to study lunar surface dynamics. The impact forcefully churned subsurface regolith across a wide area, creating a distinctive thermal cold spot and demonstrating that lunar soil turns over much faster than previously estimated. This rapid geological activity means historical surface features, such as Apollo astronaut footprints, will erode significantly faster. Understanding these frequent surface shifts provides critical safety data for engineers designing well-protected structures for upcoming crewed lunar bases.
