Using the latest data from the Chang'e lunar exploration program and other lunar exploration efforts, Chinese scientists have completed a 1:5,000,000 geological map of the entire moon, for the first time providing a more detailed global classification of the moon's late-stage geological layers and key scientific support for China's future lunar research station, landing site selection and deep-space exploration, while contributing to humanity's exploration on the Solar System's evolution, the Xinhua News Agency reported on Thursday. 
Measuring approximately 280 centimeters in length and 120 centimeters in height, the lunar geological map includes detailed maps of the moon's polar regions, precisely identifying over 13,000 impact craters and 81 basins, while classifying 14 geological structure types and 17 rock types. 
According to the map's compiling team from the Institute of Geology, Chinese Academy of Geological Sciences, the map has achieved systematic innovations in three key areas, based on the latest exploration data from the Chang'e lunar exploration program and other missions, and balancing scientific accuracy and accessibility.
The map updates the moon's geological timescale, revising the starting ages of key periods. The starting ages of the Aitkenian Period and the Nectarian Period have been adjusted to 4.33 billion years and 4.17 billion years, respectively, while the starting age of the Imbrian Period has been slightly revised to 3.92 billion years. This map for the first time provides a more detailed global classification of the moon's late-stage geological layers. 
The map also updates the moon's material inventory with high-resolution mineral distribution data and improved rock classifications. Findings from the Chang'e-4 and Chang'e-6 missions led to the identification of gabbronorite in the South Pole-Aitken (SPA) Basin, offering new insights into the moon's deep interior.
The map introduces a customized visualization system for its 1:5,000,000 scale. To meet the requirements of the 1:5,000,000-scale mapping, researchers established differentiated minimum representation scales for various geological features. This ensures that the large-scale map maintains overall readability while preserving key geological characteristics of major scientific significance. 
According to Yang Zhiming, director of Institute of Geology, the newly released lunar geological map will support China's future lunar research station, landing site selection, and deep-space exploration, while contributing new Chinese insights into the study of Solar System evolution.

。    　　摩根士丹利投资管理的Vishal Khanduja是一位业绩领先的固定收益投资者。他正在削减做空美国长期国债的押注，称美国财政部长贝森特已准备“不惜一切代价”，阻止美债收益率继续上升。

二 | 　　Khanduja是该投资管理公司广义市场固定收益团队主管。他表示，自己已经减少了对收益率曲线陡峭化交易的敞口。这类交易押注30年期与5年期美国国债收益率之差扩大，而他认为这项交易进一步获利的空间已经缩小。　　“现在很难在投资组合中持有大量曲线陡峭化头寸，因为如今长端出现了一个不以经济回报为目的的买家，”他在接受采访时表示。　　这个买家就是美国财政部。财政部上周宣布，计划将对市场上现有10年至30年期国债的购买规模至少提高一倍，以防止借贷成本进一步飙升。自该计划公布以来，5年期与30年期美债收益率之差已收窄约10个基点。　　“贝森特实际上已经亮明了底牌，”Khanduja说。他认为，贝森特的行动相当于迎来了一个“不惜一切代价”的时刻。

三 | 这一说法借用了欧洲央行前行长德拉吉2012年为捍卫欧元作出的承诺。

四 | 德拉吉当时的干预最终帮助平息了欧洲债务危机。　　Khanduja与Brian Ellis共同管理规模44亿美元的Eaton Vance总回报债券基金。

五 | 过去10年，该基金年化回报率为3.2%，约为美国综合债券指数同期涨幅的两倍。晨星数据显示，该基金过去10年的表现超过约97%的同类基金。截至周一，该基金今年以来回报约0.3%，相比之下，基准指数同期下跌0.2%。　　贝森特出人意料的计划在美国财政部公布旧债回购安排仅两周后宣布，通过减少长期国债的市场供应量，为长债提供了支撑。巴克莱策略师估计，扩大回购规模可能相当于每年增加640亿美元的购买量，约相当于目前20年期和30年期美国国债年度供应量的15%。

六 | 　　Khanduja将这一举措称为“准量化宽松”。

七 | 他表示，由于财政部正在从市场中吸收一部分久期风险，这种干预也可能提振风险资产。

八 | 因此，他已经增持投资级公司债，同时减持风险相对较低的抵押贷款支持证券，并押注美元兑收益率较高的新兴市场货币走弱。责任编辑：李安桐。
