Assigned to the ＂local products＂ of the moon! Thirteen scientific research institutions are then ＂careful＂

　　17.4764 grams of precious samples arrived at 13 scientific research institutions.

　　The lunar soil brought back by Chang ‘e V weighs 1,731 grams, and these "foreign objects" contain too much information and imagination full of science fiction. I believe you still remember this scene on our screen, which was a shocking scene shot by panorama camera after the combination of Chang ‘e V lander and elevator landed at the end of last year — — "High-definition panorama of Chang ‘e landing area on the moon".

　　Now, the lunar soil in the panorama has come to scientists.

　　Now, the first batch of 17.4764 grams of lunar soil samples have been officially handed over to 13 domestic scientific research institutions, and have arrived in Beijing, Hubei, Jiangsu and Guangdong in recent days.

　　From "going to the moon to take soil" to "studying soil separately", that is to say, scientists can finally face the lunar soil at close range. Then, how to divide the precious lunar "native products"? How to use it after "dividing the soil"

　　How to "carefully calculate" lunar soil samples? Counting three highlights

　　The lunar "local products" brought back by Chang ‘e V are so precious that they should be carefully calculated. So, how can it be used well and in what fields will it be used?

　　In this regard, Zhu Rixiang, director of the Moon Sample Expert Committee and academician of the Chinese Academy of Sciences, said that the scientific research on the Chang ‘e V sample will mainly have three highlights:

　　First, have an independent research team.According to experts, in the past, "a clever woman can’t cook without rice". In the past, scientists in China basically couldn’t get Apollo moon samples for research. Now, "there is food in hand, and there is no panic in the heart". Chinese can train its own research team.

　　Second, the Chang ‘e V sample is different from the moon samples obtained by humans in the past, and the sample is "younger".This will have a new understanding of the evolution of the moon and planets and the livability of planets.

　　Third, our goal is the sea of stars.Because new lunar soil samples will be published and distributed as planned in the future, more domestic and foreign scientific research institutions will join the study of lunar samples. Experts also introduced that in the future, Chang ‘e VI will complete the lunar sampling return, and Mars sampling and asteroid sampling have been included in the long-term planning.

　　"Every inch of land is contested": Exploring the micro-composition according to the study of "particles"

　　Yesterday, 500 mg samples of lunar soil powder have arrived at Sun Yat-sen University. In Wuhan, the first batch of 200 mg lunar soil samples also arrived at the School of Earth Sciences of China Geo University (Wuhan). 13 scientific research institutions, and the sample is only a little more than 17 grams, which can be described as"every inch of land is contested".

　　China Geo University (Wuhan) College of Earth SciencesprofessorWang Zaicong:We applied for 200 mg samples this time, and it is estimated that 50 mg samples will be lost, so the lost part may not be returned, and then we will return the remaining 150 mg. For example, some of our work has a certain loss. For example, if we want to get an average composition, we need chemical methods to deal with it. If the sample is destroyed, some samples will be lost.

　　There is water on the moon! ? There may be an answer in the lunar soil.

　　For a long time, scientists have different opinions on whether there is water on the moon or not, and they have never stopped arguing for decades. This time, can you find the answer in the lunar soil sample?

　　On earth, our communication is often affected by solar storms. Since there is no magnetic field on the surface of the moon, how can the solar wind act on the moon? In fact, these can be found in the lunar soil.
