New study ties the Moon’s South Pole–Aitken crater to a “decapitated” asteroid impact, refining a sample target for Artemis astr
A new analysis argues that a disrupted, “decapitated” asteroid likely produced the Moon’s largest impact crater, South Pole–Aitken. The debris-scattering mechanism would have delivered deep mantle material toward the lunar south pole—guiding where Artemis may land to sample ancient lunar history.
