Just a few days ago, something shocking and eventful took place in our country. If it weren't for the space agency's personal confirmation, I almost thought it was just the plot of a science fiction movie. Shortly after the successful return of the Shenzhou-13 spacecraft to Earth, China's Space Agency announced a cosmic-level project - the formation of a near-Earth asteroid defense system to protect the Earth and all mankind.
Many people will have doubts like Ah Feng, what exactly is the near-Earth asteroid defense system, and why do we deploy this system? Could it be that aliens are really coming to attack Earth?
Why are we suddenly announcing this news at this time? Don't worry, today Ah Feng will take you to explore the mysteries of space development and let you understand how China will shoulder the responsibility of protecting the earth!
To understand the role of the near-Earth asteroid defense system, we must first recognize the Earth's insignificance in the universe. There are countless stars, planets, and moons in the universe, and if they can follow their own laws, the Earth will not be threatened in any way.
However, some stars may spiral out of control in the universe and end up crashing into Earth. These stars are often referred to as comets.
In the solar system we live in, in addition to the well-known eight planets, there is also a group of troublemakers who we call near-Earth asteroids. According to a 2011 study, there are as many as 19,500 near-Earth asteroids that coincide with the Earth's orbit, of which more than 7,000 are more than 140 meters in diameter, and more than 900 are even 1 kilometer in diameter.
If these asteroids hit Earth, the damage would be immeasurable, and could even indirectly lead to the death of a quarter of humanity.
Near-Earth asteroids, despite their size, shape, and size, are most frightening in that they can suddenly change their orbit and fly directly towards us. This is one of the reasons for the extinction of the dinosaurs, when it is said that a huge meteorite hit the earth directly.
So, all near-Earth asteroids and free-flying comets are potential time bombs, ready to be overhead at any time**, and there's nothing we can do about it.
Around December 2017, an asteroid with a diameter of more than 5 kilometers visited Earth, alarming all astronauts. Although the asteroid was only 10.3 million kilometers away from Earth at the time, this was still very close in the universe, and it was even possible to photograph its appearance directly from high in the sky with a camera.
Every day, our astronauts are conducting non-stop monitoring of asteroids that could pose a threat to Earth. We are very scared that one day an asteroid may actually fly towards the Earth.
Therefore, the creation of an asteroid defense system was announced in our country in order to protect the entire planet. At present, our country is the only country in the world that has the capacity to implement this plan.
The creation of a cosmic defense system is inseparable from our large space telescopes. We have state-of-the-art Sky Eye telescopes for daily cosmic monitoring. As soon as an anomaly is detected, our space defense system will be activated to change the asteroid's flight trajectory by launching a large missile or nuclear** to ensure the safety of the planet.
Although we can't be sure that these missiles can directly hit targets on the surface of the earth, they can even hit the depths of the universe, so the surface of the earth should not be a problem!
China's Tianyan Project: Although it has not yet been realized, it shows our technological leadership and self-confidence. In the past, we kept a low profile about high-tech and engineering, but this time we are high-profile because we have absolute confidence.
This proves that our technology is already ahead of other areas, definitely ahead of some.
In our field, we are not only frontrunners, but also rule-makers. If we allow other countries or institutions to participate in our projects, then they must follow our rules.
Recalling that more than ten years ago, when we faced a technological blockade by the United States and other countries, we had a question: Why can people from South Korea and Malaysia go up, but we Chinese cannot?
Twelve years later, we Chinese have successfully sent the self-developed "Tiangong" space station into space with our own strength, and in the next few years, it will become the only operating space station in the entire solar system.
We must insist on independent innovation and board our own space station.
Our aerospace industry is in the top echelon, from the current near-Earth asteroid defense system to the "Tiangong space station", and then to the Shenzhou series, all of which are proving step by step that we are the object of your admiration.
It is an indisputable fact that Ah Feng is not brainless to brag about our country.
Although the United States has long completed the feat of landing on the moon and building a space station, why ask us for lunar soil if they try to land on the moon again? As for the International Space Station, which is about to be decommissioned, it will be a daunting challenge if the United States were to rebuild it.
When the United States built the International Space Station, it needed to cooperate with Russia, and it received financial support from more than a dozen countries. Now the United States is in trouble of its own, and Russia may not be able to cooperate with the United States in scientific research.
Therefore, if the United States wants to continue aviation research, it must resort to our space station.
Behind the announcement of the construction of a near-Earth asteroid defense system, China has conveyed a far-reaching message: the strength and strength of our great power should not be underestimated. This is because this is not only related to the interests of our country, but also related to the survival and development of all mankind.
The threat of near-Earth asteroids is ever-present, and we don't want to repeat the mistakes of the dinosaur era, so we must have a cosmic-scale defense system. Today, we have shouldered the responsibilities of a major country and demonstrated our responsibility as a major country.
In the future, we will have the potential to be leaders in more things and shoulder more responsibilities.
With the beginning of the Cold War, the United States and the Soviet Union have set their sights on the research and development of rocket technology. They understand that the use of nuclear ** is a last resort, so in the rocket race, they compete whose rocket can fly higher and farther.
This race has given impetus to the development of space technology and made human space exploration possible.
At that time, China chose to maintain its obscurity, and our foundation was weak and our industry was backward. Compared with the rapid development of the United States and the Soviet Union, our pace may be a little slower, but we are down-to-earth and have achieved 10 percent of the benefits with five points of resources, so we are leading the world in some areas.
However, behind these accolades, we must thank one person who led us into space, who made our overall defense level leap to the top of the world.
He is Qian Lao Qian Xuesen, the cornerstone of our country's aerospace industry.
Qian Xuesen is known as the founder of "two bombs and one satellite", the king of China's missiles, the father of China's aerospace, the founder of China's manned spaceflight, and one of the greatest scientists in New China.
His honors are too numerous to list in a short period of time. It is precisely because of Qian Xuesen that China's aviation industry has made such remarkable progress. U.S. Navy Undersecretary Danny Kimble once said bluntly: "I'd rather shoot him than let him leave the United States." ”
No matter how Qian Xuesen goes, he is enough to be worth the strength of five divisions. In this regard, ** also praised: "The Americans say that you are worth five divisions, but in our eyes, you are worth far more than five divisions." ”
Facts have proved that Qian Xuesen's contribution is indeed beyond imagination.
On October 1, 1949, our great man announced the birth of New China with a high-pitched shout from the tower of Tiananmen Square. At the same time, on the other side of the world, Qian Xuesen and a group of his friends were determined to return to the motherland with deep longing for the motherland and enthusiasm for contributing to the scientific development of the motherland.
At that time, New China was waiting to be developed, and the research of modern science had just begun.
Qian Xuesen, a young scientist, had the dream of returning to China for development, but was stopped by the blockade of the Americans. On the way to the port, he was forcibly detained and confiscated, along with his 800 kilograms of books and research notes.
In the interrogation room, the Americans were unable to physically harm him, but the mental torture made people feel extremely desperate.
They stared at Qian Xuesen with searchlights, just so that he could not rest for a moment, and every ten minutes, the door would be opened by the soldiers, and the door was very heavy, and every time it was opened, it would make a loud noise.
In just 15 days, Qian Lao lost more than 30 pounds. But these tortures did not give Qian Lao, and he could choose to compromise and continue to be his professor, enjoying a comfortable life in the United States.
However, instead of giving in, he chose to persevere.
On August 1, 1955, after repeated representations by our country, the United States decided to release 11 American pilot prisoners. On September 17, Qian Xuesen's family returned to China by boat, and received a secret report on the way, asking them not to get off the boat on the way, and they would send someone to pick them up after returning to China.
Qian Xuesen thought it was a telegram sent by his father, but after returning to China, he realized that it was a special instruction from ***.
During the month-long voyage, ** and Qian Xuesen's ships docked at more than 20 shore ports, but despite this, Qian Xuesen always remembered the content of the telegram and never got off the ship.
Not only that, according to Qian Xuesen's son Qian Yonggang, Qian Lao also has a special bodyguard by his side - his wife Jiang Ying. If there was any emergency when crossing the Luohu Bridge, Jiang Ying must lie on Qian Lao and block him with his body as soon as possible.
This is something they have already discussed on the ship, and it can be called a touching and profound relationship between husband and wife.
There is no problem for the Chinese to engage in missiles, why not? Foreigners can do it, Chinese can do it, we are no worse than them! ”
1.General Qian Xuesen played a key role in the rise of China's aerospace industry. In 1956, he drafted the "Opinion on the Establishment of China's National Defense Aviation Industry", which laid the foundation for China's future rocket and aerospace projects.
2.Qian Xuesen devoted his life to the development of China's aerospace industry, from the beginning of his return to China to his death, he has been involved in all the research processes of China's aerospace development, and has always served as the top person in charge of China's aerospace industry.
His contributions include China's experiment of combining atomic bombs and missiles, the launch experiment of the Dongfanghong satellite, and the blueprint for China's future aviation planning.
In Qian Lao's heart, the country is the most important, the family is light, science is the most important, and fame and fortune are the lightest. Five years to return to the country, ten years to achieve two bombs. He is the leader and pioneer of the motherland's aerospace industry, overcoming obstacles along the way, building a ladder for us to move forward with sweat and wisdom, and guiding later climbers to climb upwards.
His actions proved that science knows no borders, but scientists have a homeland. Countless examples warn us that if we fall behind, we will be beaten, and the aerospace industry represents the rise of the second Age of Discovery.
We are already ahead of the curve and will continue to do so in the future. I look forward to the prosperity of the motherland. "
