The rocket from China lifted off again, and as expected, it passed through the clouds and successfully completed the launch. In 6.5 hours, at an astonishing Chinese speed, the Shenzhou-18 spacecraft successfully connected with Tiangong and completed the docking, opened the hatch, and the three astronauts officially settled in Tiangong.

This time, they also brought something new, protective armor, is this installed on the astronauts, no, this is used to strengthen the Tiangong space station. There are still people who wonder why the Heavenly Palace is reinforced, and the quality is not up to par. And this is because Tiangong has been in orbit for such a long time, and has been hit many times.
This caused damage to the outer surface of the Heavenly Palace, which needed to be reinforced. And this is not the case for the mainland, the space stations of other countries have also been hit to varying degrees, which shows how harmful this is. The current U.S. space station, compared to our heavenly palace, is an old object, old, and there are all kinds of impact marks on the outer surface, which are caused by space debris.
The obvious void in the robotic arm may be the result of a few millimeters of space debris. So what exactly are these space debris, and what can have such power, they are actually space "garbage", various objects brought into space by humans. Rocket wreckage, spacecraft, and so on, many of them become debris, and they become hazards. According to statistics, there are millions of small space debris of various kinds in orbit.
It is so small, where does the power come from, in fact, it is its speed, they are out of gravity, they will move in a circle around the earth, and the speed reaches 7.9km/h. This speed is astonishing, can our protective armor defend against it?
The answer is yes, otherwise how to take it to space with great trouble must have undergone rigorous testing. It is understood that the armor is composed of a variety of composite materials, including a long-life inorganic thermal control coating, as well as a material version that can isolate high temperatures, and a special coating that has been used many times. These are also the materials used in the 18th spacecraft, which is also a small step for China's aerospace industry, making China's aerospace more stable.
20 years ago, the successful launch of Shenzhou 5 affected everyone's mood, Yang Liwei, as the first astronaut to go to space, also successfully completed the mission, this is a brave attempt, after all, China's aerospace at that time was still just starting, no one knew what would happen, but fortunately, we succeeded.
It's up to heaven, some people are wondering, so what are they doing in the sky, let's talk about the composition of the personnel first, first of all, the old man will lead the newcomer, Ye Guangfu, who has performed the task for 13 years, with two newcomers, although they are newcomers, but they can go to heaven after a long time of training, and they quickly adapt to the environment of the heavenly palace.
They will stay in Tiangong for half a year this time, and the first thing they have to do is to continue the mission of the 17th astronaut, and in the next five days, they will complete the docking work with the 17th astronaut, familiarize themselves with various matters, and continue to maintain the maintenance and normal operation of Tiangong. Next, it is time to go out of the cabin to complete the reinforcement of the armor.
There are various special areas in the Heavenly Palace, and every day they will have a short meeting with the ground command center before starting their day's work. They're going to be doing research in special areas, like the zebrafish on the 18th, they're going to study the ecological model, and they're going to bring goldfish algae to create the environment that zebrafish need.
Of course, it is not a blind job on it, they can also carry out recreational activities, like last time, the astronauts painted in the Tiangong, and also opened a Tiangong class to explain some knowledge. There are also dedicated workout areas to get a workout. They also treat wastewater to sustain their daily needs.
China's aerospace from a poor and white to now has its own space station, step by step of the hardships only you know, in addition to the astronauts in the sky, there are many researchers working behind the scenes, they are all good, I hope that China's aerospace can continue to move forward and conquer the sea of stars!
