Exciting!”Chang’e 5″ is about to land on the moon, and will achieve the first feat of no one taking the moon

Good news came from the Beijing Aerospace Flight Control Center on November 30. The much-anticipated”Chang’e-5” lander and ascender combination was successfully separated from the orbiter and returner combination. At 4:40 in the morning, under the precise control of Chinese scientific and technological personnel, the Chang’e-5 probe assembly was separated smoothly. Next, the orbiter and returner assembly will continue to fly on the lunar orbit with an average altitude of about 200 kilometers and wait for the ascender to rendezvous and dock, and the lander and ascender assembly will choose the best time to implement the lunar surface Soft landing, and then automatic sampling and other follow-up work.

This means,”Chang’e No. 5″ The lunar exploration mission has been half-successful. This is undoubtedly good news for the whole of China and the world, and it also demonstrates the first-class level of China’s aerospace technology. For the world, this is also the first time since the end of the Cold War, mankind has used an unmanned probe to dig earth on the moon, so this is a landmark.

What is surprising is that As the first major technological country to dug hundreds of kilograms of soil from the moon, NASA even asked China to share lunar soil data. It makes people wonder, has the lunar soil dug in the United States run out?

You know, NASA has established a laboratory of about 1,300 square meters that can store lunar soil. This laboratory has preserved about 10 Thousands of lunar soil specimens taken from the moon and picked up from the earth. After these specimens have been studied, a database has been established, which greatly facilitates the study of the moon by American scientists. But relying on these databases alone, it is impossible to know how the moon sea was formed, how the lunar volcanic activity was stopped, why the moon has no atmosphere, etc. A series of problems, so this requires more geological evidence.

But where does the geological evidence come from? Because the United States has long The lunar exploration project was stopped, so the”Chang’e-5″ probe became the only channel for NASA to obtain geological evidence. This time,”Chang’e 5″ chose to land near Mount Rumke in the northern part of the storm ocean on the front of the moon. If some soil and stones can be taken from this volcano about 2.5 billion years ago, it will help to understand the lunar volcanoes. The reason for stopping the eruption.

This research is very important, so NASA hopes that China can give itself a bit of soil. However, the power to give or not is in our hands. But considering that the United States had previously presented one gram of lunar soil to our country, in line with the principle of courtesy, we should also return one gram. It needs to be pointed out that not only the United States is reaching out for the lunar soil, but even Russia also hopes that China can share a bit of the lunar soil. This shows the importance of the”Chang’e 5″ lunar exploration mission.

It is worth noting that the”Chang’e 5″ retrieved 2 kilograms of lunar soil from the moon, and its value is more than just 2 kilograms of lunar soil! This is mainly because lunar exploration can have a huge propelling effect on national economic development, and it will bring innovation and development to the fields of materials, communications, launch, orbital maneuvering technology.

The network technology derived from the American Apollo project that year , Aerospace technology, and satellite practical technology have all proved that the moon landing project has greatly improved the national industrial level and strength. The”Chang’e 5″ lunar exploration project will surely give China a huge incentive. At the same time,”Chang’e 5″ can also inspire people, improve the pride of the Chinese nation and the right to speak in China. Therefore, we hope that”Chang’e 5″ will land on the moon smoothly and return smoothly from excavation!
