New Lunar Samples Challenge the "Late Heavy Bombardment" February 17, 2026
Results are coming out from the samples returned by China’s Chang’e-6 sample return mission to the far side of the Moon. They offer our first close-up look at the geology and history of the far side, and a recent paper published in Science Advances from researchers at the Chinese Academy of Sciences has very interesting […]
