Ouyang Ziyuan: Lunar samples of Chang'e 5 will carry out many studies such as lunar surface impact events
China News Service, Beijing, January 13 (Reporter Sun Zifa) The more than 1,700 grams of lunar samples collected from the moon on Chang'e 5 have attracted much attention after they settled in the Lunar Sample Laboratory of the National Astronomical Observatory of the Chinese Academy of Sciences.
Ouyang Ziyuan, an academician of the Chinese Academy of Sciences and senior adviser to the leading group of major special projects for the lunar exploration project, revealed on the 13th that the Chang'e-5 lunar sample will carry out many studies on the moon surface impact event and the formation and evolution of the lunar crust.
The National Astronomical Observatory of the Chinese Academy of Sciences held the 2021 New Year academic report on the same afternoon and broadcast it live on the Internet. Academician Ouyang Ziyuan gave a report with the title of "Chang'e 5, a link between the past and the next". The study on the moon samples of Chang'e 5 mainly includes the formation and evolution of the lunar soil. Records of solar activity, impact events on the surface of the moon, volcanic activity on the moon, studies on the internal structure and dynamics of the moon, systematic studies on the spectral characteristics of samples, and the formation and evolution of the lunar crust.
At the same time, the lunar samples of Chang'e 5 will also carry out a series of analysis technology research: lunar sample physical properties (electrical, magnetic, optical, mechanical, thermal, geometric properties, etc.) analysis technology; lunar sample main quantity and trace element composition analysis technology; Micro-area and micro-structure analysis technology for lunar sample minerals; isotope chronology analysis technology for the main events of lunar formation and evolution; micro-area analysis technology for stable isotope composition of lunar samples; analysis technology for solar wind components in lunar samples.
Ouyang Ziyuan said that Chang'e 5 is the most complicated and arduous task of China's lunar exploration so far, and the realization of China's unmanned lunar exploration has successfully concluded.
China has accumulated experience and technology for future manned lunar landings and lunar base construction through the implementation of lunar satellite detection, lunar soft landing detection and lunar rover survey detection, soft landing detection on the back of the moon, and lunar sampling return.
He believes that after China has basically completed its unmanned lunar exploration mission, it will plan to build a lunar scientific research platform, choose an opportunity to implement manned lunar exploration and build a manned lunar base.
When talking about China’s follow-up deep-space exploration program, the famous astrochemistry and geochemist also pointed out that lunar exploration is the starting point, Mars exploration is the focus, asteroid exploration is a bright spot, and interplanetary crossing detection is a difficult point. Go ahead".
Looking to the future, "China should fly farther, China has the ability to fly farther. We are fully capable of advancing to the sea of stars in the solar system." Ouyang Ziyuan said.
