New Moon Crater Reveals Surface Secrets | Edmonton News

Scientists just uncovered a colossal new moon crater—bigger than the Roman Colosseum—formed by a recent asteroid impact that went unnoticed for two years. This rare event, occurring once every 132 years, could reshape how we plan lunar bases, as NASA’s LRO spotted it last May. Named after Thomas McGetchin, the crater churned up material over 100 kilometers wide and revealed unexpected surface mixing, even creating a cold spot. It’s not just a headline-grabber—it’s rewriting our understanding of how fast the moon’s surface evolves, and what that means for future human missions.
