嫦娥六号月背样品揭示“广寒宫”温度密码

Core Insights - The latest research from the Chang'e 6 lunar mission reveals that the lunar mantle on the far side of the Moon is "cooler" compared to the near side, enhancing understanding of the Moon's "bipolarity" phenomenon [1][2][3] Group 1: Research Findings - The study indicates significant differences between the lunar near side and far side in terms of topography, elemental distribution, and rock characteristics, with the near side being relatively flat and containing over 30% of lunar maria, while the far side has only about 1%-2% [2][3] - The crystallization temperature of basalt samples from the Chang'e 6 mission is approximately 1100°C, which is about 100°C lower than samples from the near side, providing geological and geochemical evidence for the temperature differences in the lunar mantle [3][5] Group 2: Scientific Significance - The research on the Moon's "bipolarity" is considered crucial for understanding the Moon's formation and evolution, which may also offer insights into Earth's historical development [5] - The collaboration between the China National Nuclear Corporation, Peking University, and Shandong University has resulted in significant scientific contributions, with findings published in the prestigious journal Nature Geoscience [5]
