NASA discovers massive new McGetchin crater on the Moon

NASA researchers have identified a massive, recently formed crater on the Moon named McGetchin. The impact, believed to have occurred between April 11 and May 22, 2024, is considered the largest newly formed crater identified in the solar system. The crater measures approximately 222 meters in diameter and up to 43 meters in depth.

Data from the Lunar Reconnaissance Orbiter (LRO) revealed the feature, which was spotted by researcher Robert Wagner during a routine data-quality check. The impact was likely caused by an asteroid or comet fragment roughly the size of a three- to six-story building. Such significant impact events are estimated to occur on the Moon approximately once every 132 years.

The discovery provides a rare opportunity for scientists to study a fresh geological event. Observations indicate the impact significantly disturbed the lunar surface, ejecting material over 100 kilometers away and creating a seven-kilometer-wide cold zone due to the alteration of the lunar regolith. These findings are expected to assist in planning future crewed lunar missions and understanding space impact risks.
