NASA LRO discovers rare 221m lunar crater, once-in-century event

NASA's Lunar Reconnaissance Orbiter has identified a new 221-meter-wide, 41-meter-deep crater on the Moon, an event described as occurring once a century or less. The discovery was made by image analyst Robert Wagner during routine map updates, highlighting the value of long-term orbital monitoring. The crater's origin (impact vs. other) is not yet specified, and its significance lies in advancing lunar geology and impact frequency models.
