At 6: 00 a.m. on 10, 16, Yang Liwei landed on the grassland in Inner Mongolia in the return capsule. When he came out in high spirits, the children all took cameras and photographed this unforgettable moment.
Behind this success, scientific and technical personnel exchanged their painstaking efforts and wisdom for the success of Shenzhou 5's launch. You know, China is the third country in the world that has successfully carried out manned space activities. Although only ranked third, we are all proud to be descendants of the Chinese people! The success of this launch depends entirely on the spirit of scientific and technological personnel who are not afraid of difficulties and dare to try, so that the spacecraft can fly into space smoothly.
I feel embarrassed to compare myself. Once, when I was doing my homework at home, I couldn't work out a math problem and almost threw away my notebook. I hope I can copy my classmate's tomorrow! In contrast, the spirit of scientific and technological personnel is so precious. They are not afraid of difficulties and will not lose heart. They fight day and night every day. I, however, was awed by a small exercise, gave up halfway, and even flew into a rage. I'm really ashamed.
After that, I will study hard and work hard towards my predetermined goal. Strive to become a qualified socialist builder and successor.
2. Shenzhou 5 successfully launched a composition. At 2 1 yesterday, in the accusation hall of Jiuquan Satellite Launch Center, with the command of the commander, the Long March II F rocket was ignited in the night sky, and the Shenzhou VII spacecraft carrying three astronauts, Zhai Zhigang, Liu Boming and Jing Haipeng, flew into space in the vast and deep night sky of Gobi, and began the human spacewalk journey.
At 2 1 33, the commander-in-chief of China's manned spaceflight project announced that the spacecraft had entered the scheduled orbit and Shenzhou VII was successfully launched. ◆ The hands of the three astronauts should be held together "15 minutes to prepare!" "Good luck!" Sun Zhanhai, a 44-year-old spacecraft assembly worker, waved to the three astronauts, firmly closed the door of the spacecraft return module from the outside, and then closed the door of the orbital module.
All the people on the tower were evacuated. The three astronauts who completed all the preparations before the flight quietly lay in the return cabin more than 50 meters above the ground.
On the big screen of the command center, Zhai Zhigang in the middle seat held out his hands and shook hands with Liu Boming on the left and Jing Haipeng on the right. The commander-in-chief of China's manned spaceflight project picked up the videophone and said to the three astronauts with deep affection: "I hope you can successfully complete this mission and report to the CPC Central Committee, the State Council and the people of the whole country with excellent results!" The astronaut's confident answer came from the microphone: "Please rest assured the motherland and people!" "5 minutes to prepare!" The three astronauts checked and adjusted the restraint belt again, closed the window and calmly waited for the arrival of flying time.
◆ The Long March rocket was successfully launched for the first time 109 "... 5, 4, 3, 2, 1." With the clear and powerful countdown password of Commander Guo Zhonglai, everyone held their breath.
Guo Zhonglai, 39, was the first commander-in-chief of the Shenzhou launch. In front of Guo Zhonglai, there are five microphones side by side-broadcast, up, down, heaven and earth, heaven and earth.
Even at the last second of launch preparation, Commander Zero has the right to stop the launch in case of an accident. "Ignition-"Control Commander Xu Wenxi quickly raised his right arm and decisively pressed the thumb-sized red button.
1500 meters away from the mobile launch platform, an orange-red flame suddenly erupted from the bottom of the Long March II F rocket. The launch center accused the hall of being brightly lit.
On the wall, two huge electronic display screens of the live broadcast site were filled with red and yellow smoke instantly. 1, 2, 3, 4 ... For four seconds, the rocket still sat firmly on the launch platform.
Waiting is suffocating waiting. The 480-ton rocket seems to touch everyone's nerves.
This four-second pause is like a diver slamming off the springboard to gain momentum before taking off. A flame of several thousand degrees Celsius at the bottom of a rocket will turn hundreds of tons of water into steam in a few seconds.
The loud whistle suddenly came, and the Long March II F rocket began its seventh flight, and it also started the first 109 flight of the Long March rocket family. ◆ Since the ignition of the flight, 65,438+10,000 people participated in the manned project. At the time of 654.38+02 seconds, the tail of the rocket was pulled by some force, and the high-speed flying arrow made a slight turn to the southeast.
Rockets flying faster and farther have gradually become a bright spot in the dark. The overload pressure, which is equivalent to five times their own weight, puts Zhai Zhigang, Liu Boming and Jing Haipeng on their seats.
Three astronauts wore 14.5 kg spacesuits and curled up their legs like a fetus sleeping in their mother's womb. "Although their endurance is beyond ordinary people, they need to adjust their breathing to cope with this most difficult moment."
Huang, who sent Shenzhou 5 and Shenzhou VI astronauts into space, said. "The rocket is flying normally!" "Tracking is normal!" "The telemetry signal is normal!" "From the moment the rocket was ignited, all systems of manned spaceflight project were fully started."
Zhou Jianping, chief designer of the manned spaceflight project, said that thousands of units and more than 654.38 million people participated in the project. "Shenzhou VII report: porthole open!" When he heard Zhai Zhigang's clear report from the altitude of 1 10 km, Jiuquan Satellite Launch Center accused Yang Liwei, the first "space hero" who flew into space, of applauding.
◆ Astronauts feel good after the separation of the orbiting ship and arrow. Just as the spacecraft was about to orbit, Guo Zhonglai involuntarily shouted: "580,581,582 ..." At this time, people in the hall shouted with him. In the 583rd second, the rocket sent the spacecraft to the entrance of elliptical orbit with perigee of 200km and apogee of 350km at a speed of 7.5 km/s.
At this time, the rocket's fuel has also been exhausted, and it is about to bid farewell to the spacecraft in a tragic way. In this process, Zhai Zhigang and his two comrades experienced the process from overweight to weightlessness in less than 10 minutes.
Telemetry signals show that the blood pressure, heartbeat and other physiological indexes of the three astronauts are normal. "separation of ship and arrow!" When Guo Zhonglai loudly reported the good news, the solidified air in the hall of the accusation center suddenly boiled.
At 26: 5438 +0: 26, the survey ship Wangyuan No.5 anchored in the Pacific Ocean captured the spacecraft information. The image in the spaceship cabin is clearly displayed on the big screen of the command center.
The three astronauts looked calm. Zhai Zhigang reported: "Shenzhou VII feels good!" At 2 1 33, the commander-in-chief of manned spaceflight project * * * announced: "Shenzhou VII spacecraft entered the scheduled orbit. At 2 1 yesterday, Jiuquan Satellite Launch Center accused the hall that the Long March II F rocket ignited and blasted off at the command of the commander, breaking the night sky. Shenzhou VII spacecraft is carrying three astronauts Zhai Zhigang, Liu Boming and Jing Haipeng in the Gobi Desert.
At 2 1 33, the commander-in-chief of China's manned spaceflight project announced that the spacecraft had entered the scheduled orbit and Shenzhou VII was successfully launched.
3. Shenzhou 5's composition 2065438+June1June 17: 38, ignition, takeoff, leaving the atmosphere ... Everything went so smoothly. Shenzhou-10' s mission this time is to dock with Tiangong-1, and it will definitely complete the task entrusted by the motherland!
Shenzhou-10 spacecraft is one of the Shenzhou series spacecraft in China, and the fifth spacecraft carrying astronauts in China. Spacecraft consists of propulsion module, return module, orbital module and additional parts. After liftoff, it will dock with the target aircraft Tiangong-1 and conduct short-term manned test. The task after docking will be to build a space laboratory. The task will be to "pick up the missing pieces" of the "Shenjiu" manned rendezvous and docking technology. The spacecraft will carry three astronauts into space and fly in orbit for 15 days, which will be the first time for China astronauts to teach in space. The flight crew consists of male astronaut Nie Haisheng, Zhang and female astronaut Wang Yaping, with Nie Haisheng as the commander.
At the beginning of last century, China was a backward country. It was often bullied by other countries and robbed of its own things. However, our country has a group of indomitable people who are as strong as plum blossoms. Oh, they created China now; They decide the future of China; They also helped China to succeed step by step! China used to be a humble country, but now, Shenzhou-10 has been launched, Shenzhou-10 space has successfully rendezvous and docked, and then there is Shenzhou-11 ... China has launched so many rockets, creating a perfect miracle every time! As a native of China, I am deeply proud of my motherland!
Aunt Wang Yaping, an astronaut, is our "space teacher". Let our primary and middle school students understand the characteristics of object motion in microgravity environment, understand the role of liquid surface tension, and deepen their understanding of basic physical concepts such as mass, weight and Newton's law.
The rendezvous and docking of Shenzhou-10 space indicates that China has taken another solid step for the future space station construction. It symbolizes the rapid development of China's space industry. It reflects the development of science and technology and the prosperity of China. I wish the astronauts' uncles and aunts who are far away in space can return home in triumph!

4. Shenzhou 5's Lenovo composition countdown, ten, nine, eight, seven, six, five, four, three, two, one, launch.
In this way, China's first manned spacecraft, Shenzhou 5, was successfully launched from Jiuquan Launch Center on June 5th+10/October 5th, 2003. The next morning, "Shenzhou 5" returned safely, and everyone was very excited.
Many Beijing residents came to welcome the pilot Yang Liwei, and the scene was very lively. Astronaut Yang Liwei photographed the beautiful and spectacular earth in space and showed it to everyone on TV.
UN Secretary-General Kofi Annan also celebrated the first successful launch of China's manned space flight. China has made a new step for the international manned aviation industry. How proud it is! Of course, this achievement was created by the pilots risking their lives, and also because of the hard work and sweat of the staff behind the scenes.
Without one of them, this great achievement could not have appeared and could not have been seen by the world. Therefore, unity is strength.
Yang Liwei was selected from more than 6000 air forces 1, which can be described as the elite of the elite. The staff should also be very careful, otherwise it is impossible to build a perfect spaceship.
With so many staff, it is no small matter to ask them to cooperate. Once they don't unite, everything will be out of order.
The success of China manned aviation industry is the result of the efforts and unity of all staff. How important unity is.
5. A composition written by the spacecraft of Guanghan Palace in Shenzhou 5 On a sunny night, I quietly opened the night, hung it in the blue sky, and sprinkled Yin Hui on (the earth). My ice (jade) clean figure gives people beautiful enjoyment and infinite feelings. People have given me many nice names, such as "Suyue" and "Chanjuan" ... The children in kindergarten also affectionately call me the moon. There are also fairy tales about (Chang 'e) flying to the moon, WU GANG chopping laurel trees, and so on. So, I was covered with layers of mysterious veil. After centuries of hard work, people finally realized their wish to go to the moon. It will be a surprise to visit my astronauts by spaceship for the first time, because in their minds, I have always been beautiful: there are silver palaces and exotic flowers and plants. I only have pieces of craters, potholes and some elements that are not found on the earth. Because of lack of oxygen, animals and plants can't settle here at all. I still look forward to your visit and settlement with great enthusiasm.
6. How to write a composition about Shenzhou 5 can be done in many ways. Let's start with the history of scientific development in our country, the achievements made by women since the founding of the People's Republic of China, the contributions made by relevant departments in the space industry, and some things that intellectuals have struggled for national honor and the glory of the motherland tomorrow.
Then write some breakthroughs in the launch time of Shenzhou 5 and Shenzhou 5, and some progress in the functions of Shenzhou 5 and Shenzhou VI, which can be compared. After writing these, I will make a small summary, sum up the above contents, and then look forward to the future development of China's space industry, or the honor brought by the development of China's space industry or just the convenience brought to our lives, as well as the promotion of China's position in street navigation. These can be expanded to write. If some details are not too delicate, I still suggest you send some relevant information to avoid what you wrote being untrue or a little wrong.
Remember to use other people's things well, and you will be asked after using them. Let's go
