New advances in lunar soil research offer scientific evidence to unravel mystery of moon’s 'two faces'_我的网站

一 |      8 月 26 日消息，科技媒体 Tom's Hardware 昨日（8 月 25 日）发布博文，报道称持续约 23 年的 Linux 所有权之争告一段落，长期法律争议正走向终点。美国第二巡回上诉法院于 2026 年 8 月 10 日驳回 Xinuos 的上诉，维持纽约南区联邦地区法院此前的驳回决定。

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.

二 | 法院认定，Xinuos 的诉求已经超过诉讼时效。虽然 Xinuos 将案件表述为许可条款争议，但法院认为，其核心主张仍是代码所有权问题。

三 | 援引博文介绍，这起长期法律纠纷的诉讼起点是 2003 年，SCO Group 正式起诉 IBM，指控 IBM 违反保密协议，将 UNIX 专有代码泄露并融入 Linux 中。而事件的源头可以追溯到 1998 年，IBM 与 SCO 等公司展开 Project Monterey 合作，但后来 IBM 转向全面支持 Linux 并在 2001 年退出该项目，埋下了后续版权纠纷的导火索。Project Monterey 目标开发跨硬件架构的统一 UNIX 系统。伴随 Linux 快速崛起，项目价值不断衰减，IBM 转而全力投入 Linux 生态建设。2011 年，Xinuos 收购 SCO 的 UNIX 知识产权与相关业务，接过这场诉讼。2021 年，SCO 相关权益方与 IBM 达成 1,425 万美元（注：现汇率约合 9,600.2 万元人民币）和解；同年 Xinuos 再度发起新诉讼，将 Red Hat 一并列为被告，主张 IBM 违反非独占许可，把 Monterey 项目代码泄露给 Linux 社区。2022‑2025 年间，纽约南区联邦地区法院驳回 Xinuos 全部主张，Xinuos 随即提起上诉。尽管遭遇重大败诉打击，Xinuos 仍计划申请全院庭审重审。但据 IBM 法务方数据，该类重审申请获批概率仅 0.03%，翻盘希望微乎其微。
