Researchers in China have analyzed basalt samples retrieved from the far side of the Moon by the Chang'e-6 mission, revealing an "ultra-reduced" condition of the lunar mantle beneath the landing site. This finding indicates that these lunar mantle materials are either more pristine or have undergone significant impact events. The groundbreaking research has been published in prestigious international academic journals. This revelation enriches our understanding of the Moon's internal structure and offers fresh insights into its formation and evolutionary history.
