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.

。    11月24日上午，绥中县前卫镇三山村水果合作社内一片繁忙景象：包装车间内女工动作麻利地给苹果装箱，门口几辆货车准备往外地运送。合作社负责人康宁说，这样良好的态势，从11月初就已经开始，将一直持续到明年五一前后。         这家合作社是2010年成立的，共有114户村民参加。14年来，多采用传统的经营管理模式，即村民栽种、采摘后通过传统线下方式售卖。虽然形成合力，但由于种植方法、果品质量等相对滞后，产生的效果不太理想。         2020年，32岁的康宁接手后，立足家乡资源，改变传统管理经营模式，从山东借鉴先进种植经验，取得了不错的成绩。“我们村有黄元帅、富士、乔纳金等多个品种苹果，以往都是通过在收获前十来天扒掉套袋和反光膜等方式，让苹果长得个头大、颜色光鲜亮丽。可这样一来，不仅苹果口感稍差，而且还对环境产生不好影响。

C | 康宁说，没有扒袋的富士，颜色是白中略透着黄，客户形象地称为奶油富士。通过四年实践，市场反响非常好。         合作社成员每家秋后都能产10万斤左右苹果，整个合作社共有1000多万斤。从去年开始，康宁尝试通过线上直播的方式卖苹果。“起初，由于经验的问题，卖得不太好。

D | 经过一年运营，我各方面的技术都成熟了，到目前‘卖相’大好。”          从每天8时至17时，除了正常经营管理外，康宁均在直播卖苹果。由于他本着诚信为先、质量至上、服务暖心、价格公道的宗旨，每天能卖苹果5000斤左右。

E | “一直能卖到来年五一，估计能卖千万斤，其他少部分合作社成员自行销售。另外，合作社从村民家收购的苹果价格略高于市场价，目的是让村民得到更多实惠。例如目前奶油富士的市场价格在1.7元至2元之间，合作社收购的价格则为2元至2.3元。
