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.

。    盛夏的靖边，万物生机勃勃。位于靖边县芦河路北24号编号为6127028066的体彩实体店，一个关于责任与诚信的暖心故事悄然上演。 上个月，6127028066实体店内迎来了一位普通的购彩者。他购买了几张体彩“顶呱刮”后，便兴致勃勃地刮了起来。

二 | 刮完彩票后，这位购彩者并未进行兑奖，便匆匆离开。购彩者走后，代销者孙瑞像往常一样开始打扫桌面卫生。出于职业习惯和对购彩者负责的态度，他仔细检查了桌面上遗留的彩票，生怕有中奖的彩票被漏掉。这一检查不要紧，孙瑞果然发现其中一张竟然中了300元奖金。

三 | “购彩者肯定不知道中奖了，得赶紧把奖兑给人家！”孙瑞没有丝毫犹豫，立刻放下手中的活计，跑出店外寻找。然而，此时店外早已不见那位购彩者的身影。

四 | 面对这种情况，孙瑞没有选择将这笔奖金搁置，而是立刻回到店内调取实体店门外的监控录像。通过查看监控录像，孙瑞发现购彩者进了附近的一家超市。

五 | 超市不是很大，没多长时间，孙瑞就在超市中找到了那位购彩者。当孙瑞将奖金交到这位毫不知情的购彩者手中时，购彩者激动不已，连声道谢。“真没想到体彩店主还能把自己漏掉的奖金给送回来，太感谢老板了！”。一张小小的即开彩票，一次不经意的奖金归还，折射出的是体彩代销者孙瑞诚信之心。

六 | 在孙瑞看来，购彩者的利益无小事，哪怕只是300元的奖金，也承载着购彩者对体彩的信任。他用实际行动诠释了“责任彩票”，不仅维护了购彩者的合法权益，更在靖边县的大街小巷传递了体彩行业的正能量。

七 | 6127028066实体店在孙瑞的经营下，始终坚持合规销售、诚信服务，将每一位购彩者都当成朋友对待。这次寻主还奖的事迹，正是无数基层体彩人践行公益初心、坚守责任担当的生动缩影。孙瑞表示，他的实体店将继续秉持这份真诚，为购彩者提供更加贴心、放心的服务，让体彩的公益之光温暖更多人。
