【经济日报】四项重磅成果发布 揭开月球背面的神秘面纱

Core Insights - The research conducted on lunar samples returned by the Chang'e 6 mission has unveiled significant findings about the Moon's far side, challenging existing theories and enhancing understanding of its geological history [1][2][5] Group 1: Research Findings - The Chang'e 6 mission has revealed 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 may have strengthened around 2.8 billion years ago, contradicting previous beliefs of a continuous decline [2][4] - Water content in the lunar mantle sourced from the far side is significantly lower than that of the near side, with measurements showing only 1 to 1.5 micrograms per gram, the lowest reported value [3][4] Group 2: Implications for Lunar Science - The discovery of extremely depleted source regions for basalt on the far side provides critical evidence for understanding the Moon's internal structure and evolution [4] - The findings from the Chang'e 6 samples are prompting a reevaluation of long-standing hypotheses in lunar science, marking a shift in the field towards new interpretations of the Moon's geological history [5] - The successful integration of scientific research and engineering in China's lunar exploration efforts is positioning the country to lead in planetary science [5]
