Core Viewpoint - The research progress from China's Chang'e 6 lunar mission has unveiled significant findings about the Moon's far side, marking a milestone in lunar and planetary science [2][4]. Group 1: Research Achievements - Four groundbreaking research results have been published, revealing the history of volcanic activity, ancient magnetic fields, water content in the mantle, and mantle evolution characteristics of the Moon's far side [2][4]. - The studies indicate that the far side of the Moon experienced two distinct phases of basaltic volcanic activity approximately 4.2 billion and 2.8 billion years ago, suggesting sustained volcanic activity [5]. - The research also uncovered ancient magnetic field information, indicating fluctuations in the Moon's magnetic field strength around 2.8 billion years ago, challenging previous assumptions of a monotonous decline [5]. - The water content in the far side's mantle was found to be significantly lower than that of the near side, indicating a dichotomy in the Moon's internal water distribution [5]. - The basalt samples from the far side were identified as originating from a highly depleted source region, suggesting that large impact events may have significantly influenced the Moon's deep-layer evolution [5][7]. Group 2: Collaborative Efforts and Future Directions - The Chinese Academy of Sciences has coordinated efforts among various research institutions to maximize the scientific output from the Chang'e 6 samples, demonstrating a strong commitment to advancing space science [4][9]. - The findings from the Chang'e 6 mission are expected to enhance understanding of lunar evolution theories and promote deeper integration of academia and industry in space science [4][9]. - The research on the South Pole-Aitken basin, one of the Moon's largest impact craters, has provided new insights into the effects of large impacts on lunar evolution, marking a significant contribution to the field [7][9].
