Preface
The launch of Chang'e-6 represents a higher level of aviation technology on the mainland, and represents the rapid development of the mainland, but there are still some network "sunspots" who question that the mainland's science and technology are inferior, and it takes 53 days to go back and forth of Chang'e-6, why does the American Apollo 11 only take 8 days.
Why is there such a big difference between the time of Chang'e-6 and Apollo on the mainland?
On May 3, the Chang'e-6 probe was successfully launched, and it will take 53 days to travel to the moon, which is a very happy thing, which symbolizes the development of the mainland in the field of aviation and the growing strength of the continent, but at the same time, some people have questioned why the mainland's Chang'e-6 takes 53 days to go back and forth, while the American Apollo 11 only takes eight days.
Beijing Daily, May 3, 2024 - Chang'e-6 will go on a "business trip" for 53 days to pick "local products" on the back of the moon
This is not because the skills are not as good as others, we have to understand the Chang'e-6 mission to the moon, the main mission of this landing on the moon is to sample and return from the back of the moon, and the difficulty of this mission is very great.
Moreover, Chang'e-6, as the heaviest probe on the mainland, takes 53 days to go back and forth, because the successful launch is only the first step, and there are 11 stages in the entire mission, which can also be seen that the rapid development of the mainland's scientific and technological level and the importance of this mission.
Global Times, May 4, 2024 - Interpretation: What are the new features and highlights of the Chang'e-6 mission?
From the Earth-Moon transfer, near-moon braking to circumlunar flight, descent and landing and return to Earth, there are many difficulties, and it is also a high-profile lunar exploration project, the mission has a very long cycle, and there are many characteristics and highlights.
Apollo 11 of the United States was the first country in the world to land on the moon, when Apollo 11 took three astronauts, two of whom landed on the surface of the moon, and the reason why it could come back in just eight days was because they simply stayed on the moon for two and a half hours.
After the mission was completed, they returned to Earth, and there are many reasons for this, first of all, the supplies in the ship are the primary problem, so the shorter the flight time, the better, and simply stay and go back.
The reason why the mainland's Chang'e-6 space journey is relatively long is not because of technical problems, but because the mission is different, and this mission has many characteristics.
Chang'e-6 plans to go to an impact crater on the back of the moon to take samples back, and before that, humans have collected a total of ten samples from the moon, but all of them are on the front side of the moon.
Therefore, although the mainland's Chang'e-6 is very long, the task is very heavy, which can also be seen that it is not because the mainland's science and technology is not good, but reflects the rapid development of the mainland, and some people on the Internet are not the first time to have doubts, and some people have questioned the mainland's Chang'e-5 before.
Chang'e No. 5
Globe.com, December 17, 2020 - A detailed inventory of the 23-day sampling return trip of the five Chang'e girls
Chang'e-5 only takes 23 days to return to the moon, and at that time, some people compared the time of Chang'e-5 and Apollo 11 in the United States.
Therefore, in terms of time planning, there is a lot more abundance, so that the personnel on the ground can better observe and control each stage.
Some people have even questioned the Tiangong space station built by the mainland, feeling that it is far behind the international space station, which is much smaller in terms of size, and questioned the backwardness of the mainland's technology.
First of all, the International Space Station is built by more than a dozen countries together, and everyone should know that there are differences between people, and there are no two leaves that are exactly the same, so the International Space Station is not built to grow up, because the technical characteristics of each country are different.
The Tiangong space station on the mainland, the relatively small construction is considered from many directions, not that it cannot be built very large, first of all, in space, any small problem may lead to a disaster, and more equipment will lead to an increase in risk.
There is also a gap in equipment, the equipment in the mainland is more environmentally friendly, and it can better ensure the survival of the space station, the living of the Tiangong space station is also very comfortable, and there are not so many equipment, it looks like a warm little home.
There are always some people on the Internet who question the scientific and technological level of the mainland and the efforts made by the mainland's scientific researchers, and at the same time, it can be seen that whether it is the Tiangong space station or Chang'e-6, it can be seen that the rapid development of the mainland in the field of aviation.
Xinhuanet, February 22, 2024 -- China's lunar exploration program has gone through 20 years and has been exploring for nine days
Looking back on the past, let us can't help but sigh that the rapid development of science and technology in the mainland, the universe is very mysterious, has always attracted people, remember when I was a child, when the network was not so developed, I often heard rumors, that behind the moon, there are aliens, although with the development of science and technology, everyone knows that it is not true, but still very yearning for the wonderful starry sky, want to explore.
From the successful launch of Chang'e-1, the first step around the moon, to Chang'e-2, Chang'e-2 obtained the world's highest resolution image of the whole moon, and then Chang'e-3, which achieved the first landing exploration of the moon.
The launch of Chang'e-4 has revealed the veil on the far side of the moon, allowing everyone to see the far side of the moon, and Chang'e-5 has completed the mainland's first unmanned lunar acquisition, successfully breaking through key technologies such as lunar surface sampling, lunar take-off and ascent, and laying the foundation for the future development of the mainland.
Now that Chang'e-6 has been successfully launched, we look forward to the success of this mission, and at the same time believe that the mainland's science and technology will become more and more powerful.
When it comes to the field of aviation, you may first involuntarily think of Qian Xuesen, Zhao Jiuzhang and others, who have made great contributions to the development of science and technology in the mainland, and there are many scientific research and technical personnel, who have made a lot of efforts, which is also one of the important reasons for the rapid development of science and technology in the mainland.
The contributions made by researchers are an inspiration to countless people
Global Network, December 11, 2022 - Qian Lao, foreigners can do it, today Chinese can do it!
I believe that many people know Qian Xuesen, we can see from his photos, he is a very laughing person, he has long made up his mind to contribute to the motherland, at the age of 18 he entered Shanghai Jiao Tong University to study, and his grades are very good.
At the age of 24, he went to the United States to study, and when the People's Republic of China was announced, Qian Xuesen wanted to rush back to his homeland, but he was blocked by the United States in every way, and was also detained, placed under house arrest, etc., and once they escaped the tracking of the Investigation Bureau.
He wrote a letter of help on a piece of cigarette paper, which was sent to our motherland, and finally after negotiations, he successfully returned to the embrace of the motherland, and after returning to the country, he began to devote himself to scientific research, and was known as the "father of China's aerospace", "the father of China's missiles" and so on.
Some people even say that because of his return to China, China's research and development has been advanced for 20 years, and when looking at his diary and articles, it is very shocking, sighing at the breadth of his vision, it is difficult not to make people wonder if he is "crossing" back, and he has suggested the development of new energy vehicles in the country decades ago, and he has long paid attention to the "VR" technology, and also took a name, called "Lingjing".
Even in his later years, he still did not relax, and still insisted on paying attention to the aerospace development of the motherland.
Beijing News, April 10, 2024 - Ouyang Ziyuan: Innovation is to stand on the shoulders of giants and find the way forward in the dark
Ouyang Ziyuan, known as the father of "Chang'e", just from this title, I believe that many people can feel the contribution he has made, he was born in Ji'an, Jiangxi, his parents wanted him to study medicine when he was a child, but after seeing his determination to develop China's industry, he could only choose to support him, and he did not live up to his parents' support for him, his academic performance was very good, and the learning experience also brought him a profound impact.
And he will often tell some classmates about the moon, wanting to inspire people's yearning for the starry sky, after the success of Chang'e-1, he can't help but shed tears.
He has a variety of models of planet-related spheres in his office, which can also be seen in his determination, he has always felt that when a person connects his destiny with the country, there will be infinite motivation, and he has always practiced this sentence, and many of his studies have made great contributions to the continent and played a very key role in the development of science and technology.
On the wall of his office, there is a huge image of the whole moon, which was taken by Chang'e-2, and he is still on the front line, contributing to the development of science and technology.
There are still many people who are making contributions to the mainland's scientific and technological development, and it is precisely because of their continuous efforts that they can constantly break through technological difficulties, overcome technical difficulties, and constantly make the mainland's science and technology stronger and stronger.
summary
Although it takes a long time for Chang'e-6 to come and go, this does not mean that the mainland's technology is backward, because the task of Chang'e-6 is very arduous, which is the hard work of countless people, and the efforts of countless people, whether it is from the mainland's Tiangong space station or the successful launch of Chang'e-6, it all confirms the mainland's scientific and technological level, which is constantly developing.
At the same time, I also believe that the mainland's Chang'e-6 can successfully complete its mission, and the level of science and technology will continue to develop, and the stories of scientific researchers have inspired countless people and inspired more people to work hard and want to contribute to the country.
