The United States once built a space station, and it fell after six years of hard work. Now China has risen to a glorious "Heaven"

Humans were born on the earth, and our ancestors have lived on this blue planet down to earth for generations. He looked up at the sky, filled with awe. Regardless of eastern legends or western myths, there will always be supreme gods living in the heavenly palaces, who have boundless mana and enjoy eternal life. Ordinary people on the ground also wished to visit the Heavenly Palace at the top of Jiuxiao, visit and even live there.

As human beings have mastered the real "fairy law" - technology. Our society has undergone tremendous leaps in the past two or three hundred years. The "magical skills" that I never dared to think about before have gradually become accustomed to and improve our lives in all aspects. Aerospace technology is undoubtedly a testimony to the take-off of science and technology. "Benefits" in the second half of the 20th century, the space race between the two superpowers, the United States and the Soviet Union. Human spaceflight technology has made great progress.

The wish to travel in the sky like a god and live for a long time has finally come true. The space station is a manned spacecraft that operates in low-Earth orbit for a long time and can be visited, worked and lived by multiple astronauts for a long time. Mention it, and a giant building consisting of several cabins will definitely appear in people's minds, floating in the vast space. The spacecraft is heading for the docking module, the astronauts outside the experimental cabin are spacewalking, and the huge solar panels collect the sun's light and heat to provide a steady stream of electricity for the entire space station. Below it is the beautiful and spectacular earth home of mankind.

It is true that the space station in your mind at this moment must be the International Space Station. It is jointly built by the United States, Europe, Russia, Japan, and Canada. It is the largest and most advanced space platform currently in orbit. In 2010, it completed more than ten years of construction tasks and entered the stage of full use. After more than ten years of operation, it is expected to exit space in 2025. Some older friends may still have Russia's "Mir" space station in their minds. The overall performance of Mir is slightly inferior to that of the International Space Station. It started construction in 1976 and lasted until 1999, soaring in low-Earth orbit for 23 years.

The Mir was a product of the former Soviet Union when the United States and the Soviet Union were competing for space hegemony, and was inherited by Russia after its disintegration. When the United States and the Soviet Union competed for space hegemony, the United States later overtook the Soviet Union, manned the moon landing, and the space shuttle. Everyone must be familiar with the Apollo moon landing program, the Challenger and the Columbia space shuttle. But in that era of "comprehensive competition", the United States also independently built its own space station - "Sky Lab".

This is the first space station built by the United States. In order to compete with the former Soviet Union, the ill-fated Skylab has made mistakes from the very beginning of its launch. It has been repaired and maintained for more than six years, but it is still difficult to change it. destiny.

In 1973, after the Apollo moon landing program ended, the United States wanted to continue to lead in the space hegemony. In May, it launched the first, heaviest and most complex space station "Skylab" at the Kennedy Space Center. However, just 1 minute after takeoff, its protective cover was washed away by high-speed airflow, and the temperature in the cabin rose sharply. Skylab barely made it to low-Earth orbit with a serious malfunction.

At the end of May, the ground dispatched the Apollo spacecraft to carry out emergency repairs on Skylab, propped up a special shade sail for it to block the sunlight, and rolled out the stuck solar panels to charge and store energy for the space station. Subsequently, three groups of astronauts visited Skylab aboard the Apollo spacecraft, spending a total of 171 days on the space station.

In 1974, NASA attempted to refuel Skylab, but it failed. In July 1979, Skylab, which had been wandering in orbit for more than six years, received the last instruction from the ground operator, adjusted its attitude, avoided the densely populated area, plunged into the atmosphere, disintegrated into pieces in the raging flames, and scattered. In the South Pacific, ended a "sick" life.

Since the space station does not have the function of re-entering the atmosphere and returning to the earth, the International Space Station is expected to complete its mission and fall into the atmosphere around 2025. By then, will there be no space stations in low-Earth orbit that can do scientific research and survey the sky?

The answer is obviously no. China, a major eastern country full of curiosity and exploration of the sky since ancient times, has always had a place on the international stage in the aerospace industry. How can we be inferior to others in the construction of the space station?

At 11:00 on April 29, 2021, the Long March 5B Yao-2 carrier rocket, carrying the Tianhe core module of our own space station "Tiangong", successfully lifted off at the Wenchang Space Launch Site in Hainan. The Wentian Pod and the Mengtian Pod are also on the line. By 2024, the Tiangong space station is expected to be the only space station in orbit in the world.

People of the country who have stood up, become rich and powerful, stop worrying about why the International Space Station does not have China's participation, because it is about to fall like a "sky laboratory" and turn into the dust of history.
