China News Service, December 17th. Wu Yanhua, deputy director of the National Space Administration and deputy commander of the lunar exploration project, said on the 17th that some samples of the lunar soil brought back by Chang'e 5 will be displayed in the National Museum of Tibet for public display and popular science education.
In addition, the National Space Administration has organized research, in addition to the National Astronomical Observatory of the Chinese Academy of Sciences in Beijing as the main storage location, it will also conduct remote disaster preparedness in the hometown of Chairman Mao in Shaoshan, Hunan.
The Information Office of the State Council held a press conference on the 17th. The person in charge introduced the mission of the lunar exploration project Chang'e-5.
A reporter asked why the landing site of the Chang'e 5 mission was chosen to be in Stormy Ocean?
What uses will the lunar soil brought back by Chang'e 5 be used, and what is the significance of my country's technological development?
How will the lunar soil brought back be preserved?
Do ordinary people have the opportunity to see these precious lunar soil?
Wu Yanhua pointed out that the lunar soil brought back by Chang'e-5 includes three types of uses.
The first type, and the main purpose, is to conduct scientific research; the second type, in order to meet with the public earlier, some samples will be put into the National Museum of Tibet, displayed to the public, for popular science education; the third type, general In accordance with international cooperation conventions and multilateral and bilateral cooperation agreements, methods for the management of lunar samples and data will be issued to be shared with scientists in relevant countries and the world. Some of them may be given away as national gifts in accordance with international practices.
Li Chunlai, a researcher at the National Astronomical Observatory of the Chinese Academy of Sciences and deputy chief designer of the third phase of the lunar exploration project, said that Chang'e 5 also includes the landing process of other extraterrestrial bodies and the selection of regions. It is actually a long-term strategic research and technological iteration process. Mainly consider the following factors.
First of all, the feasibility of the project includes the factors of safe landing and topography, as well as the lighting conditions of energy supply, thermal control conditions, communication factors, measurement and control factors. Another very important factor is to consider taking samples and original places. The scientific value factor of detection.
Li Chunlai pointed out that the nine sampling sites in Russia and the United States are all in the range of 30 degrees latitude. The sampling site of Chang'e 5 selected the basalt area in the northeast corner of the storm ocean at 43 degrees. This is a brand new sampling area and a brand new sample. Research should make a lot of scientific research contributions to the weathering, volcanism, regional geological background, and regional geological evolution of the lunar surface.
"We will properly store the recovered lunar samples, including remote disaster recovery storage considerations. Most of the samples will be used for scientific research. We will carry out long-term and systematic research on lunar samples in the laboratory, hoping to be able to Deepen our understanding of the origin and evolution of the moon," Li Chunlai introduced.
In addition, Wu Yanhua also said that the precious lunar soil should be prepared for disasters in other places.
"In addition to the National Astronomical Observatory of the Chinese Academy of Sciences in Beijing as the main storage location, the National Space Administration will conduct remote disaster preparedness in the hometown of Chairman Mao in Shaoshan, Hunan Province. This is to comfort Chairman Mao, our respected great man, and he proposed that the "Looking for the moon in nine days' long-cherished wish has come true," said Wu Yanhua.
