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.

B | 作为上赛季中超联赛季军得主，受资金难题影响，广州队在本赛季中身陷困境。

C | 伴随中超联赛启用“三升三降”的升降级政策，中超“八冠王”想要完成保级目标，此战不容有失。

D | 此役两队一度战况胶着，河北队球员张俊哲的染红离场打破了比赛平衡。很快，杨立瑜在第37分钟攻入制胜球，广州队最终赢下比赛。此役过后，广州队收获了本赛季的第二场胜绩，“双杀”河北队。以“全华班”阵容出战导致广州队的进攻实力大打折扣，10场比赛仅攻入4球。但近八轮比赛，广州队单场比赛至多净负一球，证明这支“青年军”具备一定实力，且伴随赛程深入，整体表现也有了较大提升。

目前的中超联赛积分榜上，广州队积6分，与排名降级区外的大连人队仅差1分。考虑到后者因引援禁令影响，能否在该引援窗口期补强阵容暂且未知，广州队仍有机会逃离降级区。而俱乐部能否与李学鹏和张修维达成共识，为两人补充报名，或将影响到广州队在后续比赛中成绩走向。其他场次比赛，成都蓉城队以2比1战胜梅州客家队；河南嵩山龙门队以6比2大胜长春亚泰队；北京国安队以1比2遭深圳队逆转。
