BEIJING澳门六合彩, Sept. 17 (Xinhua) -- A Chinese team of scientists on Tuesday published the first research paper on the lunar samples brought back by the Chang'e-6 mission, saying that the Chang'e-6 samples exhibit "distinct characteristics" compared to previously obtained lunar samples.

The study was carried out jointly by members from the National Astronomical Observatories of the Chinese Academy of Sciences, the Lunar Exploration and Space Engineering Center, and the Beijing Institute of Spacecraft System Engineering. The research paper was published in the National Science Review journal on the day of the traditional Mid-Autumn Festival.

The team found that the Chang'e-6 soil samples have a lower density than previous samples澳门六合彩, indicating a more porous and loosely structured composition. The plagioclase content of the Chang'e-6 samples is significantly higher than that of the Chang'e-5 samples, while their olivine content is significantly lower.

The study has also revealed that the Chang'e-6 lithic fragment samples are primarily composed of basalt, breccia, agglutinate, glasses and leucocrate.

Geochemical analysis of the Chang'e-6 lunar samples has shown that their concentration of trace elements such as thorium, uranium and potassium is markedly different from the samples retrieved by the Apollo missions and the Chang'e-5 mission.

历史给东方六国足够的时间，在战国时代长达二百多年的时间里，如果六国君主能目光如炬，坚定目标，锲而不舍地进行改革，他们的实力一定会成倍增长，或者彻底地脱胎换骨，但是他们却没有很好地把握机遇，齐国、赵国、魏国、韩国、燕国、楚国都进行了内部改革，可是他们的改革始终都只是片面化、浅尝辄止式地进行，基本的人才机制都没有改革，致使国中人才认为留下没有任何前途，一个一个全都跑到秦国去效力。

The Chang'e-6 probe was launched from China on May 3, 2024. On June 25澳门六合彩, its returner made a landing in north China, bringing back 1,935.3 grams of samples from the far side of the moon.  ■
