What did the Shenzhou-13 astronauts do in orbit 183 days? We are about to become the only human beings.

At 9: 58 on April/KOOC-0/6, 2022, Shenzhou XIII successfully landed on the ground, and three astronauts completed a long business trip in space for/KOOC-0/83 days. So what did they do on the space station? How far has our space station been built? Why is China Space Station about to become the only space station for mankind?

As we all know, there are two space stations floating in our space orbit, one is the International Space Station and the other is China's Sky Space Station. What is the leading star of the International Space Station doing? I think everyone knows better. If you are not sure, you can read the following news:

The International Space Station can be said to be the most important aircraft of mankind so far. It took more than 20 years to build it, and many human-related experiments have indeed been completed in orbit, but it is really aging. It was predicted that it would be retired in 2024, but because the cost of building another space station is too high, the United States proposed to retire it in 2030 through maintenance, but there is a problem here. Maintenance costs a lot of money, and

Russia is the main builder of the International Space Station, undertaking the construction of important components such as the power system of the core module, and the daily supply of these materials is also completed by their rockets. The International Space Station actually has a clear division of labor.

The United States is the property of the space station community and is responsible for the power supply, sanitation and other services of the international space station community. Because this warehouse built in the United States is partly connected with super-large solar panels; Russia is mainly responsible for the adjustment of the flight attitude and position of the International Space Station, because the power for the flight of the International Space Station is on the Russian cabin, which means that if the International Space Station wants to make any orbit change or attitude adjustment, it needs power from Russia.

But the question now is, the two sides are already very unhappy, so can the future cooperation be maintained? Even if the current operation of the space station can be maintained because of its own interests, if the service life is to be extended, a lot of real money must be invested, which can be said to be a comprehensive restoration. It's too difficult for two people who are quarreling to sit down and design a plan and then go Dutch.

And more importantly, because each country has built its own cabin, it is impossible for anyone to go directly without going through another country. For example, even if the United States invests a lot of money and wants to take over the space station for maintenance, what about this cabin built by Russia? This is the power cabin, and so is Russia.

Therefore, the International Space Station is likely to retire in 2024 according to its expected life, when Tiangong will naturally become the only space station for mankind. Any space station experiment that wants to be completed in space must be applied for in China and approved by China. Of course, China naturally has the right to participate in these experiments. After all, your tenant is doing experiments in my house. I'll definitely see if it's safe. What if it's harmful to the house?

Speaking of the space station, I have to say that the three astronauts have done a lot of things on the Shenzhou-13 spacecraft, and almost everything has set a new record, which also makes our space station more and more perfect.

1, survival, fine decoration of hydropower network: It took 183 days from the entry of Shenzhou XIII astronauts into the space station to their departure, and three people lived on it for half a year. There is basically no problem from food, clothing, housing and transportation to eating, drinking and having fun. This verification tells the world that our space station has matured and maintained its long-term survival.

2. Going out of the cabin only depends on whether it is necessary: During the mission, Shenzhou XIII participated in two outbound activities, both of which were attended by commander Zhai Zhigang. Coupled with the first extravehicular activity in China's space history, Zhai Zhigang became the first astronaut to perform three complete extravehicular activities in China's space history. At the same time, Wang Yaping is the first female astronaut in China, and Zhai Zhigang and Wang Yaping are also the first in China. This tells the world that there is nothing wrong with our extravehicular technology.

3. Docking, have you ever seen a remote-controlled spaceship? On June 8, 2022, Ye Guangfu, astronaut of Shenzhou XIII, completed the rendezvous and docking test of the combination of "Tianzhou II" spacecraft and space station by manual remote control. This means that in the future, if there is a program problem when the drone enters the International Space Station, the space station can be controlled by manual remote control to ensure safety. This means that our follow-up spacecraft carrying materials does not need to send astronauts, so we can rest assured that they can dock. Double insurance, no problem!

4, mechanical arm, 20 meters long scissors, are you afraid? The space station was not built at one time. It needs to be launched several times and then assembled in space. But generally speaking, these parts are docked at the forward docking interface. But there is no problem docking the first section. What should I do if the second quarter is docked again? Then we can only use the mechanical arm to turn the cabin weighing dozens of tons over and put it in other docking ports, leaving the vacant docking for the next one. It can be said that this is a space crane!

We all say that space flight is a process to the sea of stars, but China Space Station will soon become an important high-speed service area on the road to the sea of stars, and we will serve the future here.
