Seven thoughts on the return of the thirteen knights of god to the earth.

The smooth return of the Shenzhou XIII spacecraft showed the high-tech exploration achievements of China Tengfei, and let the whole world see the space spirit of China people. Here, I will share with you some of my thoughts on the return of the Shenzhou XIII crew to Earth. Welcome to read!

Experience of the 13th Regiment of God returning to Earth: 1

With the development of astronomical observation technology, modern spacecraft has brought people into a brand-new space age. I love the universe, and I love space flight even more. My ideal is to be a soldier in the space industry, travel in space by manned spacecraft and explore the universe.

My understanding of space flight is superficial. I think flying planes and rockets into the sky is space flight. The research in the space field is very extensive and in-depth. No matter how deep or shallow my understanding of space flight is, I like space flight very much.

I remember that my favorite toy as a child was an airplane, and now I have two well-preserved remote-controlled airplane models at home. I still remember when I was in the middle class of kindergarten, my grandfather and I made a rocket model and watched the exhibition in the whole kindergarten. In primary school, I joined the model airplane interest group, in which I made six model airplanes. When the model plane I made flew in the sky, I thought of Uncle Yang Liwei, who traveled in space in a manned spaceship built by our country. This pioneering work has won us honor in China before the whole world.

With the continuous growth of age and knowledge, my understanding of space flight has gradually deepened, and at the same time, questions in my mind have followed, such as: How did a rocket fly without wings? Will the satellite fall into the sky? Another example: Why can manned spacecraft travel in space? ..... With these questions, I bought some encyclopedias about "Universe, Space and Natural Science". Through the study, I initially learned that the rocket is an aircraft that uses the engine to inject high-temperature and high-pressure gas backward to generate force and get forward thrust, so as to move forward. Generally, it consists of three parts: power system, control system and structural system. Satellites and space probes are unmanned spacecraft with highly complex automatic control devices. So far, they have visited the moon, Venus, Mars and Halley at close range or on the spot, and achieved fruitful results, so people call them "scouts of cosmic information". In addition to launching satellites and detectors into space, humans also want to fly into space. Manned spacecraft is one of the tools for human beings to travel in space. It generally consists of cockpit, track module, service module, docking module and emergency rescue device. The cockpit is the core of the spacecraft, the orbital module is equipped with various experimental instruments, and the service module is the place to provide life support for astronauts. Manned spacecraft can carry out space activities independently, and can also serve as a "ferryman" between the ground and the space station, and can dock with the space station or other spacecraft for joint flight. Tiangong-1 and Shenzhou-8, independently developed by China, successfully docked in space for the first time at 1 1 36 am on October 3. This is the third country in the world to master the automatic space rendezvous and docking technology after the first rendezvous and docking test between the United States and Russia in more than 40 years. This shows that our country's space technology has reached the top level in the world, and I am proud of it. At the same time, I love space more.

I am a child and the future of my motherland. I know that there are still many mysteries waiting for us to explore and discover in the universe, and there are still many difficult problems waiting for us to understand and overcome the key problems in the space field. Therefore, in order to realize my beautiful ideal of exploring the universe in space and make contributions to my beloved space career when I grow up, I will study hard scientific and cultural knowledge, firmly master excellent skills and strive to be an excellent young pioneer from now on.

Reflections on the return of the thirteen knights of God to the earth II

Manned space flight is the most complex, difficult and demanding system engineering in human space activities. According to the space station construction mission plan, the 1 1 mission will be carried out this year and next, including three space station module launches, four cargo spacecraft launches and four manned spacecraft launches. In 2022, the on-orbit construction of the space station will be completed and the National Space Laboratory will be built. After that, the space station will enter the application development stage.

Every task is a "big project", with the hard work and wisdom of thousands of people behind it. In order to ensure the smooth implementation of the task, all units of each system made every effort to prepare for the war and greeted it with excellent results.

Deep in the Badain Jaran desert, the vertical assembly test workshop of Jiuquan Satellite Launch Center is brightly lit and crowded, and the staff walks between the spacecraft arrow and the test instrument, running around day and night.

The aerospace industry has been described as "a thousand people with one arrow", and any link is related to success or failure, and no one can treat it lightly. As the home port for China astronauts to enter and leave space, Jiuquan Satellite Launch Center has built a safe "ladder" with meticulous attitude.

"The hoisting team of dozens of people cooperates with the task, and every step of operation can't go wrong, and the hoisting and docking error is even smaller. Each product can only be hoisted and landed successfully once, and there is no chance of turning over and no mistakes. When hoisting the docking rocket, dozens of bolts in a circle should be aligned and connected at one time. " Shi Chuangfeng, the base staff, undertakes the lifting work. In order to be fast and steady, he invented his own training method, tied a covered electrode to the hook and operated a crane to insert beer bottles from high altitude. At the end of the exercise, he and his colleagues waved the heavy crane iron arm as flexibly as they waved their own arms.

Thousands of flights, safety first. Taking the life safety of astronauts as the bottom line, the Shenzhou-12 manned spacecraft team of China Academy of Space Technology has made plans and measures to ensure the safety of astronauts at all stages of launch, flight, docking, docking and return of Shenzhou-12, and will also start the emergency rescue mission mode of manned spacecraft for the first time to fully ensure the safety of astronauts to and from heaven and earth.

Only by truly understanding where the starting point and road of manned spaceflight project are, can we draw strength from history and make better progress. The Shenzhou 12 manned spacecraft will be launched by the Long March II F- 12 carrier rocket. During the preparation of the mission, the temporary Party Committee of the Long March II F- 12 launch vehicle team of China Academy of Launch Vehicle Technology led everyone to the Dongfeng Revolutionary Martyrs Cemetery to remember the heroic deeds of Marshal Nie and many revolutionary martyrs, and called on everyone to complete the mission with a strong sense of responsibility, superb technology and brave spirit, and firmly hold the baton.

Reflections on the return of the thirteen knights of God to the earth 3

From Shenzhou 5 to Shenzhou XIII, from the ascendant to the vigorous development, the pace of China people's marching towards the vast universe has steadily advanced with the inspiring rise of the nation. The Chinese nation's exploration of the infinite universe is endless. From the goddess the Goddess Chang'e flying to the moon in ancient mythology to the Shenzhou series in the new era, it bears the infinite exploration and yearning of China people for the unknown universe. In this great space journey, behind every step of innovation and progress, it is inseparable from the hard work, unremitting efforts and hard work of generations of astronauts, laying a solid foundation for the tenacity of the national space industry. The application of aerospace industry has a great impact on all mankind, and rejuvenating the country through science and technology is the most important policy of the country. The successful return of Shenzhou XIII marks that China's space science and technology has entered a new stage, showing the world China's ability to stand on its own feet and improve its international prestige. Moreover, we can also find that only under the correct leadership of the party and the government and with the joint efforts of the people of the whole country can society continue to progress, science and technology continue to develop, and our life will be better!

On April 6, 2022, three China astronauts who had been on a business trip for 183 days finally returned home smoothly. At 9: 57 am, the Shenzhou 13 capsule landed successfully at the Dongfeng landing site in Inner Mongolia, and stood upright after landing for the first time since Shenzhou VI. The whole process of returning to the cabin and leaving the cabin is exciting. After watching the live broadcast, I can't calm down for a long time. Recall that hundreds of years ago, humans traveled around the world with wheels and sails; A few decades ago, man landed on the moon with the help of rockets. Today, with the help of the "500-meter spherical radio telescope (FAST)", we discovered the bright Milky Way from light years away. With the help of China Space Station, dream of space and travel in space. From the discovery of the new continent to the exploration of the stars in the universe, the scientific development of mankind cannot be separated from the unremitting efforts of generations of scientists. As a strong aerospace university, Harbin Institute of Technology bravely undertakes the mission of innovation in the process of national development and construction, and consolidates the foundation of strengthening the country through science and technology; As an adult of Harbin Institute of Technology, while I am proud, I also feel the responsibility for the development of the new era. I will continue to contribute to the development of the motherland in the future.

Struggle is the wing of a round dream. Generation after generation of astronauts have worked hard in the "experimental field" of aerospace, their hearts are full of latitude and longitude, and their feet are embedded in the vast sky. They struggled hard on the basis of poverty, strove forward in repeated experiments and pursuits, pursued Excellence under the challenge of Excellence, dared to break through difficulties and bravely opened up new roads. Astronauts learn experience and excellent skills in strict, systematic and comprehensive training. Flying sightseeing and walking outside the cabin need a solid foundation, excellent psychological literacy and strong physique. Hard training in summer and winter gives them super willpower and self-confidence. For the great aerospace industry, astronauts and astronauts regard hardships and twists as a "ladder" for their career development, forge their backbones with ambition, accumulate strength with backbone, and achieve higher-level innovation and breakthrough in the aerospace industry through continuous struggle. From the successful launch of Shenzhou-1 to the cosmic journey of Shenzhou 5, Shenzhou VI and Shenzhou VII ... China's manned space flight has achieved fruitful results. On the road of "chasing dreams", every time is a brand-new journey, and every time is an unprecedented challenge. Of course, unprecedented challenges and difficulties have also created unprecedented heights.

Reflections on the return of the thirteen knights of God to the earth 4

From Shenzhou 5 to Shenzhou XIII, from one person a day to three people in half a year, China people have never stopped walking towards the sea of stars.

More than half a century ago, a song "Dongfanghong" resounded around the world. Today, bright China red shines in space. From "two bombs and one satellite" to "manned space flight", "space dream" has long been integrated into the great "Chinese dream" and has become a brilliant stroke in the development of human civilization.

The missions such as "Chang 'e" going to the moon, "Beidou" guiding the way, "Tian Wen" asking the sky, "Tiangong" visiting the victory, "Jade Rabbit" exploring the moon, "Zhu Rong" exploring the fire and "xi" exploring the sun are full of the profound cultural heritage of the Chinese nation, showing the exploration achievements of China's space flight to climb scientific and technological peaks again and again, and showing the great China Road and China spirit.

Dreaming for nine days and then asking for heaven, striding for a new journey of strengthening the country. The Chinese nation's exploration of the infinite universe is endless. You can spend nine days on the moon, catch turtles in five oceans, and laugh and laugh. Behind every step of innovation and breakthrough in space travel, it is inseparable from the hard work, unremitting struggle and independent innovation of generations of astronauts. They have become the common memory of a country and a nation.

It is another golden autumn in October, which was once a dream of home and country. This space trip will not only set a new record for China people's stay in space, but also carry out more space science experiments and technical experiments to produce high-level scientific achievements. We can also spend the Spring Festival in space with them ... Scientific exploration will once again play a concerto with the space dream.

"Flying dreams never lose weight, and scientific dreams have unlimited tension." Just as Wang Yaping, a female astronaut, said before going out to war, as long as you dare to dream, dare to pursue dreams and build your own dream spaceship with wisdom and sweat, you will be able to meet the launch moment of your dreams and fly to the vast starry sky that belongs to you!

This time, Shenzhou XIII has many "bright spots": compared with Shenzhou XII staying in space for three months, this time it is half a year, three astronauts will spend the Spring Festival in space, and we will receive the New Year greetings from space for the first time on earth; This is the first time that a female astronaut from China has entered the China Space Station, and astronaut Wang Yaping will also become the first female astronaut in China to carry out extravehicular activities. This time, the space station will conduct radial docking by autonomous rapid rendezvous and docking for the first time; This manned mission will carry out 2 ~ 3 extravehicular activities and so on.

From Shenzhou-1 to Shenzhou-13, from 2003, when Yang Liwei was the first astronaut in China, he realized his Millennium dream of traveling in space. Up to now, there have been 12 people in China, and China's space industry is making great strides. The grand project of space station construction will be completed step by step in an orderly manner, and we firmly believe that it will go smoothly in the future; With the unremitting efforts of generations of China astronauts, the space dream related to human peace and progress will definitely come true, and we are full of confidence in it.

For China people, behind this excitement, there is more calmness. Behind decades of aerospace industry is a great road to national rejuvenation. We have experienced the struggle of the country and felt the rapid progress of this country in the changes of daily life.

In the future, we will also witness the launch of Shenzhou XIV and Shenzhou XV. Every witness has strengthened people's confidence in the country and the future. It is an indisputable fact that the strength of science and technology is getting stronger and stronger. It is a change that people can see and touch, not just an illusion. Therefore, this is not only a story of China astronauts passing on their dreams from generation to generation, but also a story of people becoming more confident, the country becoming stronger and the nation becoming more hopeful.

We can't help looking back on the past. The more we look back on history, the more we can understand the present. The more you look back, the more you cherish it. We will constantly review every important node of China's scientific and technological undertakings, and look for the motive force of national progress in these landmark events. Those moments, because memories become eternal.

Reflections on the return of the thirteen knights of God to the earth 5

In ancient times, people always wanted to launch some detectors into space. However, a single function cannot complete people's exploration of space. So, people began to think of ways: how to let people go to heaven! This time, the Long March II rocket and Shenzhou XII spacecraft were used.

Last time we went to space, we spent a lot of money. If we only go up for three or four hours and think it is not cost-effective, we want to build a place like a hotel where astronauts can live, that is, the space station.

According to the plan, Space Station 1 consists of five parts: the first part is a "manned spaceship", which mainly carries astronauts; The second one is the "Quest Experiment Module", which is used to do some experiments that cannot be completed on earth; The third is the "dream experiment module", which is similar to the "real experiment module" and is also used for experiments. The fourth is the "Tianhe core cabin", where Chinese astronauts live; The fifth type is "cargo ship", which is mainly responsible for transporting all kinds of materials. However, this plan has not been completely completed. At present, the space station has only two parts: Tianhe core cabin and cargo spaceship. It is said that in 2022, the space station will be completed.

Legend has it that there is a Guanghan Palace. On the moon, our space station floats in space. The sun radiates "energy" to the earth every day, but when we bask in the sun on the earth, the sun is far away from us and the danger is very small. Astronauts who spend too much sun in space may get cancer, so it is stipulated that the space station should not be higher than the earth 1000 km. After considering various factors such as funds and experimental results, scientists finally built a space station 400 kilometers away from the earth.

On the earth, everything you throw will fall to the ground. This is Newton's "gravity". If we stand on the flat ground and throw things, we will fall down; Then if we "throw" the spaceship at a very fast speed, it will fall to the same extent as the radian of the earth, and then the spaceship can fly along the earth. The space station flies very fast, and it can circle the earth in an hour and a half.

Since ancient times, it is impossible for people to see the whole sky on the earth. If you can see clearly from the space station, you can see far, because you stand tall. In the space environment, we can do some experiments that we can't do on earth, such as finding some chips smaller than mobile phone chips, or things that can change color in some environments.

There are several small goals for astronauts to go into space this time: to live for about three months; Debugging all kinds of equipment; Do some incredible experiments; Get out of the cabin and see the whole picture of space and space station.

China's space station allows us to explore more mysteries of space.

Reflections on the return of the thirteen knights of God to the earth 6

In order to stimulate students' interest in learning science, popularize space knowledge, carry forward space culture and feel the mystery of the universe, all teachers and students in primary and secondary schools in Qi Xinyou organized to watch the first lesson of "Tiangong Classroom" co-sponsored by China Manned Space Engineering Office, Ministry of Education, Ministry of Science and Technology, China Association for Science and Technology and Central Radio and Television General Station on February 9 15:40. More than 3,500 teachers, students and parents attended.

The first lesson of "Tiangong Classroom" is the first space lecture of China Space Station, which embodies the concept that the space station serves the national education, shows the strong national strength of China and shows the warmth of education in China. Shenzhou XIII astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu had a wonderful space science class on the space station. Three astronauts will introduce the working and living scenes of China Space Station in orbit, and demonstrate the phenomena of cytology experiment, buoyancy disappearance experiment, effervescent tablet experiment, object movement, liquid surface tension and so on in microgravity environment. They explain the physical principles behind the experiment and communicate with the ground class in real time to spread the knowledge of manned space flight. The students are surprised at the phenomena of various objects in space. Every popular science experiment has aroused students' great interest, attracted more children to look up at the stars, and let the great aerospace spirit and scientific spirit take root in students' hearts. Students share their feelings with their families, write in diaries and draw on paper, showing their enthusiasm and dreams of advocating science, loving space and exploring the unknown.

If you can't get on or off, why should you take the exam? Light and dark, who can be the best? Feng Yi just likes it. How did you know?

Man has begun to explore the universe. Today, we watched the astronauts of Shenzhou XIII give us a space lesson. What they said was vivid and lifelike, and we listened with relish.

They told us some space experiments, and we also know that space is buoyant. If you squeeze a drop of water, it will float around in the air. Besides, if you turn the cup upside down, not a drop of water will flow down.

They did an experiment. They put a ping-pong ball into the water. Then it's time to surprise us. They are holding a tube with a ping-pong ball in front of it. First, they press it, and then they quickly take it away. "Wow!" The students were all surprised. It turned out that table tennis actually sank into the water, and he was still tightly attached to the cup. If it is on the ground, then table tennis should float and not sink! The students were surprised from ear to ear. This experiment is really amazing!

Although this is a simple lesson, I feel the magic of the universe from it. I must be an astronaut in the future and drive a rocket to distant space! But I know I must study hard now and serve my country when I grow up!

Reflections on the return of the thirteen knights of God to the earth 7

At that exciting moment, astronauts Zhai Zhigang, Wang Yaping and Ye Guang Fu successively entered the Tianhe core cabin, and the related work will be carried out as planned.

China's high-tech development has advanced by leaps and bounds, Shenzhou VII has been successfully launched, and a major breakthrough has been made in the research and industrialization of 5G Internet. The first world-class high-speed railway between Beijing and Tianjin was opened in China, the first research achievement of human genome sequence was published in China, the major reconstruction project of Beijing Electron-Positron Collider was successfully completed, and Dawning 5000A ranked among the top ten supercomputers in the world.

The dragon dives deep, and Chang 'e explores the moon. China's scientific and technological strength is constantly improving. Major scientific and technological achievements are constantly emerging, and scientific and technological innovation is increasingly active, injecting new vitality into high-quality economic development.

The Millennium dream is realized today. On July 23 last year, Tian Wen-1 was launched from Wenchang Space Launch Site by the Long March 5 Yaosi carrier rocket and successfully entered the scheduled orbit. Tian Wen-1 arrived on Mars in February, 20021,and captured it. In May, 20021year, the orbiter was lowered, the landing patrol was separated from the orbiter, the surface of Mars made a soft landing, and the rover left the landing platform to carry out patrol detection, so as to scientifically detect the surface morphology, soil characteristics, material composition, water ice, atmosphere, ionosphere and magnetic field of Mars, and realize the technological leap in the field of deep space exploration in China [5]. Deep space exploration will promote the all-round development of space science, space technology and space applications, and make greater contributions to serving the overall development of the country and enhancing human welfare. As of February 3, 20021year, the total flight mileage of Tianwen-1 probe has exceeded 450 million kilometers, which is about 654.38+700 million kilometers away from the earth.

We are standing at the historical intersection of "two hundred years", and the new journey of building a socialist modern country in an all-round way is about to start. The journey is long, only struggle. Through struggle, we walked through Qian Shan. We will continue to struggle, forge ahead and create greater glories!

The astronauts of Shenzhou XIII will stay in orbit for six months as planned. During this half year, the main task is to further verify the key technologies for the construction and operation of the space station. Specifically, it should be further verified with the core cabin, Tianzhou No.2 and Tianzhou No.3.

Strong science and technology, the country is strong. The road to self-confidence is successful, which is praised by China Aerospace. The successful launch of Shenzhou XIII manned spacecraft once again made us feel the strength of our motherland.
