Chinese scientists have made new progress in the study of lunar soil samples returned by the Chang'e-6 mission, providing fresh evidence to the striking differences between the moon's near and far sides, which have long puzzled scientists.
Because the moon is tidally locked to Earth, its rotation period matches its orbital period, meaning the same side always faces Earth. The moon's near side features vast dark basaltic plains known as lunar maria, while its far side is dominated by bright highlands with far fewer maria, creating a striking contrast between the two sides. Why does the moon have such "two faces"?
Scientists studying the moon's early formation and evolution have long used the lunar magma ocean model as a basic framework. Under the model, the chemical and isotopic characteristics of different types of lunar magma can be explained by the mixing of different components in varying proportions after the magma ocean cooled, Guangming Daily reported on Saturday.
However, previous lunar samples were collected only from the moon's near side, while significant differences exist between the near and far sides in their topography, composition and internal structure.
Against this backdrop, the research team from Institute of Geology from Chinese Academy of Geologist Sciences studied feldspathic impact-melt rocks in lunar soil samples returned by the Chang'e-6 mission. Using China's first independently developed ion probe system, researchers conducted a comprehensive analysis to test the lunar magma ocean model and examine how large impacts reshaped reservoirs in the lunar crust and mantle.
Through high-precision analyses, the team identified key clues to the moon's evolutionary history, suggesting that the stark differences between its near and far sides may be linked to the ancient giant impact that formed the South Pole-Aitken Basin.
The study found that the massive impact continued to profoundly reshape the lunar crust and upper mantle after the lunar magma ocean had solidified, fundamentally altering the material composition of parts of the moon's far side.
The findings add to the traditional lunar magma ocean model, suggesting that the formation and preservation of the moon's crustal and mantle reservoirs may have varied significantly from region to region and cannot be fully explained by a single, uniform model of primordial magma-ocean differentiation.
The research provides new scientific evidence for understanding the differences between the moon's near and far sides, while offering fresh insights into the moon's complex evolutionary history, according to Guangming Daily.

。孩子们用湿毛巾捂口鼻，老师们根据指定逃生路线，带领幼儿弯腰快走迅速撤离。在逃生的过程中，幼儿能做到安静并且井然有序，快速集中到操场的安全地带。安全第一，确保有序，责任明确，落实细节。孩子们有序疏散到安全地带后，各班教师迅速清点人数，并将撤离情况汇报总指挥人员进行记录。遇到火灾逃生技巧发生火灾时要首先报警当火灾发生时，不要慌，先拨打119，请求消防员的帮助。迅速逃离现场发生大火时要以最快的速度逃离现场，冲出烟雾包围的房间时，要用一块湿毛巾捂住口鼻，免得发生呼吸不畅的现象。生命最重要，千万不要因为寻找贵重财物而耽误逃生的时间。不得乘坐电梯楼房起火时，不乘普通电梯逃生，因为起火很容易断电，或者使电梯轿厢受热变形卡壳而使逃生失败。低姿前进不能在浓烟弥漫时直立行走，否则极易呛烟和中毒。逃生过程中一定要低姿前进，身体保持在1米以下。标有“安全出口”的通道逃生在逃离火灾现场时，要沿着标示有“安全出口”的通道逃生，不要随便进入不明通道。
