The moon’s oldest and largest crater didn’t form in the way astronomers thought, according to a detailed analysis of its shape, which would rewrite the moon’s early history. The South Pole-Aitken (SPA ...

When astronauts land near the moon's south pole as part of NASA's Artemis program in a few years, they likely will find themselves in an unexpected treasure trove of clues that could help scientists ...

The South Pole-Aitken impact basin on the far side of the Moon formed in a southward impact (toward the bottom in the image). The basin has a radioactive “KREEP-rich” ejecta blanket on one side of the ...
