The Moon is not just a simple inert and frozen star. Its hidden face actually houses the remains of the most violent cataclysm in its history: a titanium crater of 2,000 kilometers in diameter. While the origin of this giant scar, the South Pole-Aitken Basin (SPA), has long divided the scientific community, new models [...]
Water ice gets the Artemis headlines, but simulations suggest a decapitated iron-cored asteroid scattered something far more valuable across the lunar south pole billions of years ago
The largest impact scar on the Moon was likely gouged out by a massive asteroid that struck at a shallow angle, its iron core shearing off and carving the basin’s lopsided shape. The finding has direct consequences for NASA’s Artemis program: deep mantle material flung outward by that ancient strike should sit within reach of astronauts landing near the lunar south pole. The South Pole–Aitken basin spans roughly 1,600 miles across the Moon’s far…
