Experience and Comprehension of the Second Lesson in Tiangong Class in 2022 (Eight Articles)

The second lesson of Tiangong Classroom introduces and displays space science facilities, aiming at spreading and popularizing space science knowledge and inspiring young people's enthusiasm for pursuing "scientific dreams" and realizing "space dreams". The following is my experience and understanding of the second lesson in Tiangong classroom. Welcome to read!

Experience and understanding of Tiangong Classroom 1 the second lesson

Tiangong is a space station independently developed by China. Needless to say, the name "Tiangong" was not casually named. It's like a palace with everything.

The space station is a "space hotel laboratory", where astronauts can stay for a short time and conduct various space research and experiments. Then why build a space station? The space station can test all kinds of technical equipment that may be used for space flight in the future. You can also get a "weightless" environment-a special environment that is difficult to stay on the ground for a long time. However, the cost of going to and from space is quite high. Being able to stay in space for a longer time at a time can reduce costs and improve work efficiency. So such a place with comprehensive functions that astronauts can live for a long time was born.

First of all, introduce the planning of our "palace".

Tianhe core cabin is the bedroom in the palace, mainly for astronauts to live in. Goods and manned spacecraft are used to transport goods and people, just like vehicles on the ground. The candlestick experimental module and the dream experimental module have not been completed yet. They are R&D laboratories in the "Palace" for various space experiments and scientific research.

There are all kinds of imaginable dangers in space, among which the threat comes from the sun as we know it. As we all know, the sun is the foundation of life on earth. It provides endless energy and nourishes the growth of all things. But the X-rays and gamma rays it releases are very deadly. These two rays can easily penetrate your skin and destroy all cells in your body. Then why can we bask in the sun every day on the earth? That's because the earth's magnetic field and atmosphere will reflect or absorb them. This safety factor must be considered in the site selection of the space station. Internationally, the distance from the ground 1000 km is generally chosen. For the sake of safety, our "Tiangong" is located 400 kilometers above the ground. This can be protected by the earth's magnetic field and atmosphere, killing two birds with one stone.

In ancient times, it was said that the Temple of Heaven was in the clouds, and all kinds of immortals lived there. At present, many astronauts and scientists live in the "Tiangong". They are working hard for the progress of China's space science and technology in high altitude, so that we can no longer rely on foreign technology, and we can really look at the whole universe while overlooking the earth and have a deeper understanding of space.

So our "heavenly palace" is really a veritable heavenly palace! Perhaps this is the origin and beautiful meaning of the name "Tiangong".

The door of "Tiangong" has been opened, and the future can be expected!

Experience and experience of the second lesson of "Tiangong Classroom" (II)

The aerospace industry has always been a vivid epitome of a country's pursuit of innovation and development. Since the 1990s, China's manned spaceflight project has now reached the third step, namely, "building a space station to solve the problem of large-scale and long-term manned spaceflight application". The Long March V-B carrier rocket will undertake the important task of launching the space station cabin in the future, and its first flight is of great significance, which is related to whether the "three-step" strategic goal of manned spaceflight project can be realized. Faced with the adverse effects of the COVID-19 epidemic, the astronauts overcame many difficulties, won this tough battle, and strengthened their confidence in completing the follow-up mission. The launch of the Long March V-B carrier rocket is the achievement of China in building a space power and a world science and technology power. It also once again showed people the powerful spiritual strength of not being afraid of risks and challenges and being brave in breaking through and climbing.

Pushing open the door of the space station era, China Aerospace has demonstrated its confidence in unswervingly following the road of independent innovation with China characteristics. The launch time of the Long March V B carrier rocket was announced in advance, and finally the rocket was launched in a "zero window" within one second. From Shenzhou-9, Shenzhou-10 to Long March-5 B carrier rocket ... The launch times of several missions were announced in advance, accurate to the minute, which fully demonstrated the confidence of astronauts.

Self-confidence comes from 16 manned space flight since the launch of Shenzhou-1 spacecraft, and also from the consciousness of always implementing and adhering to quality first and safety first in the manned space flight project with the most complex system and the highest safety requirements. Self-confidence is not only honed by "grinding a sword for ten years", but also depends on climbing and challenging the unknown. After the successful launch, the words: Dare to overcome all difficulties and obstacles and dare to climb the peak of space science and technology are printed on the screen of the lobby of Wenchang Space Launch Site. Struggle is a reward for the strugglers. China's space sword is boundless, and the "Long March" is always on the road.

Exploring the vast universe, developing the space industry and building a space power are our unremitting pursuit of the space dream. From the first man-made earth satellite "Dongfanghong-1" to the beginning of the space age, and now to the space station age, China Aerospace has once again embarked on a new journey. The space station is an extremely complicated and challenging step, but the huge gains will be unparalleled, which can accelerate the pace of exploration, development and utilization of the universe in China and even mankind. The leap of space station and space technology can also promote space achievements to benefit social development and people's lives more widely and deeply. As a pioneering work in near-earth space, the construction of the space station will lay the foundation stone for further realizing the longer-term goals such as manned lunar exploration and Mars exploration, and become a symbolic innovative practice of serving the country by space and strengthening the country by science and technology.

Experience and experience of the second lesson of "Tiangong Classroom" 3

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 in the sky and getting out of the cabin requires a solid foundation, excellent psychological quality 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 I to the space trips of Shenzhou 5, Shenzhou VI and Shenzhou VII ... China's manned spaceflight project 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. Mr. Lu Xun once said: "In fact, there is no road on the ground. If there are more people walking, it will become a road." The road comes from two feet and is developed step by step. Since the development of China's space industry from 65438 to 0956, self-reliance and independent innovation have been consistent in the development, which is the core competitiveness to promote the development of space industry. It is bound to take detours to take the road that predecessors have not taken, and it is bound to encounter setbacks to break through the hurdles that predecessors have not taken. Only by being a pioneer can you become a pioneer. Only by daring to break through can we break a new world and seize the "new highland".

Great cause breeds great spirit. Looking back on the development history of the aerospace industry, whether it is the successful launch of "Dongfanghong-1" or the great achievement of Shenzhou manned spaceflight project; Whether the Beidou satellite navigation system is completed in an all-round way, or the "Chang 'e" flying to the moon and "Tian Wen" exploring fire, from bold ideas to successful practice, China's space strength that keeps pace with the times has been demonstrated. China's space industry has gone from a difficult start to a difficult journey and then to brilliant achievements. It left behind China's figure and China's footprint in the vast space, and it left behind China's spirit and China's strength in the development of the space industry. This spirit and strength will surely lead the 65.438+0.4 billion China people to unite as one, work hard, forge ahead on a new journey and dream of a new era.

Experience and understanding of the second class in Tiangong No.4 classroom

Xinghai didn't stop, and space heroes came out again. At 0: 23 on June 6th, Beijing time 10, Shenzhou XIII manned spacecraft carried three astronauts from China into space, namely Zhai Zhigang, Wang Yaping and Ye Guangfu, who became the second batch of "residents" of the space station and the core module of China. The live broadcast of the Tiangong classroom left a deep impression on people.

From the launch of Shenzhou-1 in 1999 to the launch of the first astronauts of China Space Station in June 20021,China people's desire to "settle down" in space is being realized step by step. Over the past 22 years, we have witnessed the history of China's manned space flight from weak to strong, and netizens on social media have also praised China's space flight: "The pace of progress has never stopped" and "Great China, Great China people"!

Things change, and years are like poetry. Every launch, flight and transcendence of China space show the world our space journey from scratch, from existence to excellence, and from earth to space. This process seems to be an understatement, but the real journey is unforgettable. During the National Day, the film My Father, which tells the story of parents and grandparents' silent sacrifice and dedication to the construction of new China, exploded on the screen. One chapter, Poetry, is a tribute to China's space flight. In the eventful autumn of early research in the Gobi Desert, young couples who are fireworks sculptors and space engineers told their children: "Mom and Dad are people who write poems in the sky." After her husband died, her wife propped up her career and family with weak shoulders. This touching scene made the audience break through the defense line. If patriotism is the deepest emotion, then struggle is the longest confession. The figures dedicated to national rejuvenation and the aerospace industry, together, are a magnificent human poem.

"In China, looking up at the stars. There is poetry in the heart and home in the distance. " Speaking of poetry, the name China Aerospace has the romantic connotation of China people. The lunar exploration project is called "Chang 'e", the lunar rover is called "Jade Rabbit", the global positioning system is called "Beidou", the space station is called "Tiangong", and the Mars probe is called "Tian Wen" ... As an uninterrupted civilization among the four major civilizations in the world, Chinese civilization has countless fairy tales and historical legends, which sparks with China's cutting-edge high technology, making China's space flight both "traditional" and "modern". Named the manned spaceship "Shenzhou" is full of beautiful meanings.

China people changed from "tourists" to "tenants" when the Shenzhou 13 manned spacecraft rushed to the universe-the change of "identity" represents the enhancement of national strength, and this kind of national pride arises spontaneously, which should be remembered in the hearts of every Chinese son and daughter. This space lecture is not only full of creativity, but also means that the legend of China's space flight will be extended to more profound and unknown fields. China's space flight is moving towards a higher goal, which is the "heart yearning" for the boundless space. I believe that this poetic confession in the name of the country will eventually condense into a common aspiration of "struggle, Chinese children"!

A lecture on "Space" touched the hearts of countless people in China. If we are more proud of the success of the launch and recovery of manned spacecraft in the past and in the past, what we are proud of now is the vivid and beautiful display of space technology and experimental details. What did the space class bring us?

The first is the influence on teenagers' scientific exploration spirit. Aerospace science and technology can strengthen the country, revive national prestige and bring national cohesion, which may be somewhat abstract in the past. However, in the face of the scientific demonstrations in the Tiangong class again and again, people will sincerely lament the strength and advancement of space technology, and national pride will arise. Tiangong classroom not only shows young people scientific principles and miracles, but also provides the most vivid opportunity for patriotism education.

The second is the impact on the scientific literacy of all citizens. Interesting "teaching in space" makes some boring physical formulas come alive, visible and tangible. A drop of water contains many scientific principles. The weighing of an astronaut involves simple application of science and technology, which not only interests young people, but also makes adult audiences like science better. Aerospace science and technology is not empty and difficult to understand, but ultimately serves scientific life, which is very beneficial to cultivate the scientific literacy of the people.

The third is the influence of space technology on changing life. There are many civilian technologies in space science and technology. Every progress and development of space science and technology will greatly promote the development of civil science and technology. Electronic thermometer, dried noodles, diapers, heart pumps and liquid supplements are all civilian products of aerospace science and technology. Nowadays, "space vegetables have been widely planted to serve human life, and space technology has contributed."

The fourth is the influence on interesting education. I believe that even students who don't want to learn scientific knowledge will think that science can be so interesting, vivid and practical, from water drops to weightless simple pendulum motion, from the axis motion law of gyro to the tension and capillary phenomenon of liquid. If we can be more interesting, intuitive and vivid like "space teaching" in our usual educational activities, we can learn scientific knowledge from boring to interesting, which will not only inspire more children to join in.

In short, in the face of the vast universe, we are all students and can't take it for granted. In the past, many of us thought that astronauts must think the sky was blue. Through this lecture on "Space", we know that the space seen by astronauts is a bright black sky, and technology is always a magic weapon for a country to be invincible. Space technology is not only powerful, but also related to the science and happiness of our family and life. The Chinese dream is down-to-earth, and the technological dream has unlimited tension!

Experience and experience of the second lesson of "Tiangong Classroom" 6

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.

Experience of the second lesson of "Tiangong Classroom" 7

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.

Experience and experience of the second lesson of "Tiangong Classroom" 8

Wang Yaping, an astronaut from China, gave a popular science class to primary and middle school students in Tiangong-1, which is more than 300 kilometers away from the earth. Innovative teaching methods, intuitive physical phenomena and so on. Will sow the seeds of love for aerospace and science for children and open the door for young students to know the world and pursue their dreams.

The vast universe and boundless space have fascinated all mankind since ancient times. In ancient China, there were many legends and stories, such as the Goddess Chang'e flying to the moon and Kuafu. There are too many unknowns and endless mysteries in space waiting for human beings to explore and discover.

Through the teaching of "Tiangong-1", children know why water droplets appear in a different state from the ground in space, how to measure the mass of objects in weightlessness, and what is the mystery of gyro rotation ... This is an intuitive embodiment of the development achievements of China's space industry and a concrete achievement of human pursuit of space dreams. With the progress and development of science, the pace of human exploration of space will not stop. Looking up at the starry sky, it takes generations to advance wave upon wave.

The magnificent and mysterious starry sky has attracted countless pioneers and wise men. With wisdom, courage and even life beyond the times, they left Hui Ze's great achievements in later generations. Copernicus published "Heliocentrism" by looking up at the stars. Bruno defended and developed Copernicus' theory with his own life and blood ... Looking up at the starry sky beckons generations to think and explore, so that the great scientific spirit can take root among the people, so that the tree of thought can flourish and illuminate the journey of human civilization and progress.

Compared with the deep and vast universe, human life is short and small. But it is because of the existence of life and dreams that the lonely universe is full of vitality and significance. Pursuing dreams requires not only looking up at the scientific ideals and spirit of the starry sky, but also down-to-earth and diligent practice. Looking up at the starry sky will make people stand higher and see farther, and let people know how to understand the relationship between individuals and heaven and earth, and how to understand their responsibilities to the country and history in their limited lives. If the individual life is closely linked with the destiny of the country, the nation and the people, and the individual dream is placed in the collective dream, the meaning of life will be more profound if we are not arrogant and persistent.

There are more people looking up at the stars, and a nation has hope. Let more students look up at the stars and inspire their passion to explore the mysteries of the world. The future of the Chinese nation will be broader and the Chinese dream will be more magnificent.
