嫦娥六号月壤四项研究成果发布—— 首次揭开月球背面演化历史

Core Insights - The recent findings from China's Chang'e 6 mission have unveiled significant research results regarding the Moon's far side, published in the journal Nature, which challenge previous understandings of lunar evolution [1][2]. Group 1: Research Findings - The study reveals two distinct periods of basaltic volcanic activity on the Moon's far side approximately 4.2 billion and 2.8 billion years ago, indicating sustained volcanic activity [2]. - Ancient magnetic field data from the far side suggests that the Moon's magnetic field strength may have increased around 2.8 billion years ago, indicating fluctuations in lunar activity rather than a steady decline [2]. - The water content in the mantle of the Moon's far side is significantly lower than that of the near side, highlighting a "bipolarity" in the Moon's internal water distribution [2]. - The basalt samples from the far side originate from a highly depleted source region, suggesting either extreme depletion of the primordial lunar mantle or significant impact events that led to melt extraction, indicating that large impacts may have greatly influenced the evolution of the Moon's deep layers [2]. Group 2: Implications for Lunar Science - The successful outcomes of the Chang'e program exemplify the deep integration of science and engineering, marking a shift in China's planetary science from a following role to a competitive and potentially leading position in certain areas [2].
