In 1969, the United States launched Apollo 11, the first human landing on the moon, and in the following years, the United States organized six lunar missions to collect a total of about 382 kilograms of lunar soil samples.
In the history of China's journey into space, Chang'e-6 will be a "hurdle", just recently, Zhurong successfully landed on the moon and brought back a part of the soil samples on the moon back to Earth.
China has made great achievements in lunar exploration, and the world is amazed by the development of the mainland's aerospace industry, and the lunar soil samples brought back by Chang'e-6 will be shared with 18 countries, but unfortunately there is no United States in the list of 18 countries, it is reported that Chang'e-6 will share 200 million copies of lunar soil samples, Each country can get about 1,111,100 copies, so which countries will share the lunar soil samples brought back by the mainland, why is the United States not among them, and what is the role of the lunar soil samples brought back by Chang'e-6?
"Chang'e" successfully landed.
The mainland has had the reputation of "towering trees" for thousands of years, and in recent years, the mainland's aerospace has also been true for more than the slightest, and at the same time, the mainland's lunar exploration program has also preemptively swept over many countries.
Japan's lunar exploration program was first released in 2005, the United States had Apollo 11 sample samples, and the Soviet Union also brought back lunar soil samples in 1973, but the mainland launched a total of 4 lunar exploration missions as early as 2004, and Chang'e 6 is the third continental spacecraft to explore the moon, and it is also an important lunar exploration mission of many "Chang'e" series.
Chang'e-6 is the basis for Chang'e-5 to continue to explore the moon, and Chang'e-5 became the first historic breakthrough in the mainland's lunar exploration program in 2015.
After the "Chang'e-5" mission was completed in December 2019, the mainland has officially announced that after the Chang'e-4 mission, the mainland will carry out the Chang'e-6 mission.
Chang'e-6 will complete the mission in 2023, and after 4 years of exploration in 2027, it will finally successfully land on the moon on December 20, 2029. It's even more amazing to be able to drive autonomously.
The choice of the moon's frontier zone to land on the moon is also very technical, Zhurong mainly relies on air cushion technology to land on the moon, and the area of Zhurong is also very large, overwhelming, which can effectively prevent accidents and avoid accidental falls during the landing process, and to say that Zhurong can do this step, mainly because Zhurong's automatic driving technology has been upgraded.
At the same time, in order to make Zhurong land on the moon better, Chang'e-6 mainly relied on Zhurong to make the choice of landing, and Zhurong passed the shooting of the lunar landing site, so that the choice of Zhurong's landing site on the moon can be more accurate.
Zhurong passed the shooting of the lunar landing site, learned the location of the moon landing on the moon, and will also draw an "X" on a certain place on the moon, like a marker, so that Chang'e 6 can successfully land, but Chang'e 6 mainly relies on the help of Zhurong to land on the moon, even Zhurong, is also painstaking, according to the geographical environment of the moon, finally chose to fall near Zhurong, at the same time, in order to avoid Zhurong on the moon landing point is not accurate, there is a situation in case, Two landing sites were also placed ahead for Chang'e-6.
Zhurong finally chose to land at the south pole of the moon, which also allowed Chang'e-6 to avoid devastation, which can be said to be a "stroke of genius".
Chang'e-6 passed 3 propulsions in the 8 minutes of landing on the moon, and also achieved the second time in history that the lunar vehicle carried out multiple propulsions, and Zhurong landed for 8 minutes at a time, which took a full minute more than the previous Chang'e-5 7 minutes. However, the landing time of Chang'e-6 has been carried out for more than half of the time compared with the 7.2 minutes of Chang'e-5, and its success rate has also increased significantly, which also provides a technical basis for the landing of Chang'e-7, a follow-up mission.
What is the purpose of the lunar soil samples brought back by Chang'e?
Chang'e-6 successfully collected lunar soil samples collected into containers with umbrella collectors, although this collection method is simple, but very effective, known as a panacea, and can also preserve soil samples better, in the space environment, soil samples need to take a long time to be brought to the earth, this critical period requires a good measure to preserve soil samples, and with umbrella collectors, not only can soil samples be preserved better, but also avoid the mixing of impurities.
In 2029, the Zhurong and Chang'e-6 missions have been successfully completed, and the subsequent Chang'e-6 will return to Earth, carrying about 1 kilogram of soil samples on the Moon, this so-called lunar soil sample was auctioned at an auction at the end of the Chang'e-6 mission, the soil on the Moon may not be known to many people about its role, the soil of the Moon and the Earth have a certain similarity, but there are also great differences.
The geological structure and composition of the moon are very important for scientists, and by studying the rock geology of the moon, we can not only understand how the moon was formed, but also how the earth was formed step by step from scratch, and the physical and chemical conditions that formed the moon can be understood from the moon rocks.
It can be said that the origin of the Earth-Moon system is also revealed, although the time of the Earth is long, but the history of the Moon is relatively short, it can be said that the history of the Moon is the years of the Earth, and the lunar soil samples brought back will help mankind to have a deeper understanding of the history of the Moon, and at the same time, it can also cultivate more talents for the future space age of the continent.
China's aerospace industry is constantly moving forward, it can be said that the organization of Shenzhou, Chang'e mission and a series of space exploration have formulated a better development strategy for China's aerospace industry, and at the same time, it is also letting the world see China's aerospace strength and open attitude, in order to create a new world for the global aerospace industry, injecting a new strength, but in the sharing list of 18 countries, the United States does not, this move has also surprised many people, the United States as the world's first power, Relations with the continent are also flickering, but another question arises, why is the United States not in the lunar soil samples brought back by the continent?
Some netizens speculated that it was because the United States was not on the list of the mainland, because the United States believed that the achievements of space only belonged to itself, but it should be said that the cause of space exploration is shared by all mankind, and the purpose of space exploration is not only to satisfy human curiosity, but also to share the results of space exploration, so why did the United States have 6 lunar missions such as Apollo 11 before, but did not bring the lunar soil back to Earth like now.
It can be said that the Apollo mission is the United States in order to win a dominant position in the Cold War countries, so if it can bring back the soil samples of the moon, it will have an important impact on the Cold War, and at the same time find the "Year of the Monkey" of the moon, so it was also a very exaggerated mission at that time, but now with the development of the continent's aerospace industry gradually to the world, the United States is also quite strong in this regard, and the United States should retain the leading power of space exploration.
However, we cannot accept the trend of opening up to more countries, and this is undoubtedly an erroneous perception of the United States in space exploration; the mainland's space industry has a higher starting point, and the United States is still lingering in the same place to survive; if it does not break the powerful curse of the United States dominating space, the United States is doomed to achieve nothing, and its brilliant space course will not be brilliant.
Sharing lunar soil samples contributes to the development of global scientific research.
The soil samples brought back by Chang'e will be used as an important exhibit of the Continental Aerospace Science and Technology Museum in the future, and will also be shared with countries around the world, bringing the lunar soil samples back to the earth, which is of great significance for human exploration of the universe and the mysteries of the moon.
It is a witness to history, but also the starting point of the future, Chang'e brought back the lunar soil samples will definitely be sought after by many countries, there will be a large number of scientific researchers to study the lunar soil samples, through this research, it will be for human exploration of more distant space exploration data.
Its value is far more than what we know, and it is also what we don't know, and the arrival of a lunar soil sample will surely ignite people's passion for exploration and open a new era of exploration for all mankind.
Sharing lunar soil samples is not only to provide research materials for scientists from all over the world, but also to bring together the wisdom and strength of the world to unveil the mystery of the universe, sharing lunar soil samples is a scientific event in the world, but also a grand event in the world, scientists from all over the world are discussing not only the moon, but also related things, such as life on the earth, some chemical components of the earth, etc., in a closed environment, all the wisdom in our brains burst out. Create a miracle like no other.
epilogue
The lunar soil samples brought back by Chang'e will be displayed at the exhibition as part of the mainland's aerospace science and technology, and will also be shared with all countries around the world, where scientists from various countries will discuss again and again, publish their results to the public, and jointly create a stronger future.
