A violent impact that carved out the moon's largest impact basin may have scattered deep lunar material near the lunar south pole — right where NASA plans to send Artemis astronauts.
A new study suggests the South Pole–Aitken (SPA) basin, an impact crater more than 1,200 miles (2,000 kilometers) wide on the moon's far side, was likely created by a differentiated asteroid. The findings might answer some of science's biggest questions about the SPA's creation — and they could have major implications for future lunar exploration.
