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.

B |     週日清早，WNBA常規賽有比賽進行，火焰客場挑戰水星。水星過去4場輸了3場，反觀火焰過去4場贏下3場，此消彼長之下，火焰此行有力帶走勝利。
    
    　　水星今季至今表現不理想，目前錄得13勝22負，37.1%的勝率排在前8開外，近況方面，雖然上仗與火花的交手，憑藉著艾莉莎湯瑪士和布查特等人的出色發揮，水星最終94比87擊敗對手，但這是她們近4場首場勝利，整體表現還是較為糟糕。期間進攻乏力是水星近期戰績不佳的主因，過去4場有多達3場得分在83分以下，此番面對近6場均場得93.5分的火焰，水星主場要被打回原形。陣容方面，K.柏林傷缺。
    
    　　進入8月份，火焰率先開啟一波五連主的比賽，不過她們開局不利，主場連續不敵狂熱和火花，幸好之後2場主場擊敗節奏和暴風成功反彈，雖然最後1個主場再次輸球，但對手是聯盟一姐天貓，失利實屬非戰之罪。五連主之後，火焰開啟了三連客之旅，上仗客戰暴風，碧捷卡列頓和卡拉莉特等主將幫助球隊半場領先雙位數，下半場頂住對手反撲，最終火焰有驚無險以84比82擊敗暴風，此番走訪近期敗仗居多的水星，火焰劍指連勝。人手方面，菲亞根因傷避戰。
