It is understood that the Shenzhou 12 astronauts are returning to the ground from the space station for the first time, andthe manned return module will land at the Dongfeng landing site for the first time. The return of spacecraft to the ground shallbe completed jointly by spacecraft system, astronaut system and landing site system. When the spacecraft returns to theground, the spacecraft must first leave the original flight orbit, then enter the earth's atmosphere along a descending orbit,slow down through friction with the air, and land safely on the ground. It can be divided into four stages: the first stage is
braking deceleration stage. First, the docking mechanism between the Shenzhou 12 spacecraft and the Tianhe core moduleis separated. When the spacecraft runs in the last circle in space, the ground sends a return command to the spacecraft toadjust the attitude, and then uses the engine on the spacecraft propulsion module to ignite, so as to reduce the speed of thespacecraft and enter the orbit of returning to the earth.
The second stage is the free taxiing stage. After the combination of return module and propulsion module leaves theoriginal orbit, it will descend freely in unpowered flight state. The third stage is the re-entry stage. After re-entry into the
atmosphere, the spacecraft makes another adjustment so that it can accurately return to the landing site. The fourth stage isthe recovery landing stage. After the re-entry module lands safely, its positioning system starts to work to indicate its location,so that the search and rescue system can find the target in time.
According to relevant experts, the return of the Shenzhou 12 spacecraft is more difficult than ever before. First, beforeShenzhou 12, manned spacecraft returned to the earth from a fixed orbit, but this time, in order to save the propellantconsumption of the space station, the orbit of the space station will not be adjusted for the return of the spacecraft, so thereentry point of the spacecraft is not fixed. Second, Shenzhou 12 no longer landed at the main landing site of Siziwang flagcommonly used in the past, but at the Dongfeng landing site. As the landing site is located in desert and Gobi, and there arealso high convex or pothole terrain such as mountains, search and rescue is more difficult than ever.
In addition, astronauts returning to the ground will first undergo a 14 day medical isolation period, the main purpose ofwhich is to adapt to the gravity of the earth's surface. Then there is the medical convalescence period, which lasts between20 and 30 days. At this time, the astronauts will further recover, enhance their physique and restore their physical state beforegoing into space.

At 9:22 on June 17, 2021, Shenzhou 12 manned spacecraft went up to heaven. Three astronauts were sent into space.They are Nie Haisheng, Liu Boming and Tang Hongbo.
I think they should be very excited! Especially Tang Hongbo, when he went into space for the first time, would he feelvery nervous and afraid? Before the spaceship flew out of the atmosphere, uncle Tang Hongbo was really curious. He turnedhis head to see the scenery outside the spaceship. He seemed to think: the universe is really beautiful! I love it! I thought: if Iwere uncle Tang, I would want to stick my face on the window and look out of the window all the time. Uncle Liu Boming isreading the materials, and uncle Nie Haisheng is also doing things seriously. Uncle Tang Hongbo is naughty again. He maywant to see if the pen will float in the air, so he threw it up, and then he threw up the information... His curiosity is so strong!He seemed to think that space was so interesting!
After 6.5 hours, they finally reached their destination - the China space station. At 15:54, Shenzhou 12 completeddocking with Tianhe core module, but the three astronauts did not enter Tianhe core module until 18:48. I think: they are
really not easy. And the three uncles have to do some work in the sky and core module. They have to stay for three months toreturn to the earth. They are so great! I'm really proud of our country - China! 3.有关神⾈⼗⼆的英语作⽂
At 9:22 on June 17, Shenzhou 12 spacecraft flew out of the earth. It flew out of the earth on the Long March 2 rocket! Three astronauts are sitting in the spaceship. They are going to fly to the Chinese space station. Nie Haisheng has beenin space for the third time. He is an experienced captain. Liu Boming is still very excited about his second time in space.Tang Hongbo looks very excited. This is his first time aboard the spaceship! They are all wearing thick spacesuits. Hecarried a big backpack on his back, a heavy helmet and a round mask on his head. This spacesuit has good sealing. It ismade of high-tech materials. It's expensive!
On the spaceship, Tang Hongbo looked very excited. He looked east and West for a while. He stretched his head to thewindow and looked at the earth in the universe like a big blue water ball. After a while, the water ball becomes smaller andbecomes a glass ball with white clouds on it. He wanted to stick his face to the window and didn't want to come down. NieHaisheng glanced at him and smiled, as if thinking: I had been like this in those years. After a while, Tang Hongbo becamerestless again and threw his pen into the air. The pen flew around in the air and returned to his hand. He seemed to think: it'sfun. Do it again. In this way, the folder was also played by him. Liu Boming smiled in a magical voice, as if thinking: you areso interesting!
Today, I wish the three astronauts a happy father's day and the motherland's aerospace industry more and moreprosperous!
