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.

。几个月前，Bird 已经宣布裁撤 23% 的员工，试图在财务上实现收支平衡、并期望实现盈利。更重要的是，今年 6 月，纽交所已经向估计过低的该公司发去摘牌警告。

B | 该公司将有六个月的时间来恢复合规要求，意味着 Bird 必须在连续 30 个交易日内、将股价维持在至少 1 美元的水平。此外在当月最后一个交易日，公司股价也必须高于 1 美元。当时 Bird 在纽交所上的交易价格低至 0.56 美元，但周二盘后交易价格仅 0.37 美元。

C | （公平点说，还是上涨了 1.01%）资料图在昨日的一篇博客文章中，Bird 将盈利过程中遇到的一系列阻碍，归咎于在缺乏强有力监管框架的城市运营。其解释称：当前的宏观经济状况，在短期内创造了这样一个环境。要求该公司提高财务纪律水平，并明确区分我们近期可实现完全自我可持续经营的市场。此外 Bird 声称已审查其它城市组合，并淘汰不适合运营的市场区域 —— 尤其是那些竞争激烈、共享交通工具供大于求、且街道上过于拥挤的城市。
