Excerpt: In October 1989, the Sun spit a blast of high-energy particles into the solar system. Earth’s protective magnetic field kept us safe, but the Moon received an intense dose: More than 8 times the radiation received by plant workers during the Chernobyl nuclear disaster scorched the barren lunar surface. As NASA’s Artemis III mission prepares to return explorers to the Moon in 2025, scientists are working to protect them from this kind of unpredictable outburst from the Sun and other radiation from deep space. To do this, they’re turning to the Moon’s natural barriers. By mapping the topography of the lunar surface, researchers have calculated the shielding potential of each mountain range, crater wall, and shadowed slope near the south pole—Artemis III’s target. Their work will guide decisionmaking for the landing location of this mission and beyond....
