The lunar sample laboratory was made public for the first time. What is the role of the sample laboratory?

In recent times, everyone’s attention has been attracted by Chang’e 5. Chang’e 5 has now successfully rendezvoused with the orbiter and the assembly. This means that Chang'e 5 has achieved China's first lunar orbit rendezvous and docking in the aviation field, which is a milestone and is also related to the subsequent development and research in the aerospace field. After the lunar samples obtained by Chang'e 5 arrive on Earth, how will they be stored, managed, and analyzed and studied? After the lunar samples collected by Chang'e-5 return to Earth, they will be stored in the lunar exploration project ground application system of the National Astronomical Observatory of the Chinese Academy of Sciences for processing and analysis. my country's first lunar sample laboratory has also been made public for the first time. All preparations have been made and it is ready to receive lunar surface samples brought by the Chang'e-5 return module at any time. ?

After successfully handing over the lunar samples, at 12:35 on December 6, the Chang'e-5 orbiter and returner assembly successfully separated from the ascender and entered the lunar waiting stage, preparing to choose an opportunity to return to Earth. The Chang'e-5 spacecraft is expected to land on the grasslands of Inner Mongolia in the middle of this month. It is understood that the Chang'e-5 mission obtained two types of lunar soil samples. One is to use a grabbing device to obtain lunar surface soil, and the other is to use drilling equipment to obtain lunar rock samples 2 meters deep under the lunar surface. The two samples are separated store. ?

The laboratory is affiliated to the National Astronomical Observatory of the Chinese Academy of Sciences and the Lunar and Deep Space Exploration Research Department. ?The laboratory has a slogan of "safe unsealing, scientific processing, and proper storage", which shows the laboratory's rigorous operation of the entire process of lunar sample processing.

It is worth mentioning that there was no atmospheric environment when Chang'e-5 was sampling, and the inside of the sample device was vacuum, making it difficult to unseal. For this reason, the laboratory specially developed a vacuum unseal device to ensure that the sample is not destroyed. In the future, lunar samples will be divided into permanent storage and temporary storage. Permanent storage means permanent preservation; temporary storage means placing it in the laboratory for physical and chemical analysis and for scientific display purposes.
