Story summary

Jeffrey Andrews-Hanna, a planetary scientist, argues a massive asteroid impact formed the Moon's South Pole-Aitken basin, striking from the north.
The research ties the basin to near-side KREEP, a concentration of potassium, rare earth elements, and phosphorus.
The far side's thicker crust likely pushed magma toward the near side, driving volcanism.
Future Artemis missions will collect samples to test these ideas and reveal the Moon's early history.
