Reflections on the Tiangong Classroom in 2022 1
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!
Reflections on the Tiangong Classroom in 2022 (II)
Since ancient times, people have been full of reverie about the vast universe. With the development of science and technology, mankind has gradually stepped into space exploration. But the voice of doubt is gradually coming: is exploring outer space a waste of people and money?
Today, due to the limited earth resources, the world's space powers have stepped into outer space, which is vast and rich in space resources, such as high vacuum, solar energy, the moon, tiny planets and so on.
In addition, the gps navigation system closely related to people's lives is also inseparable from the development of aviation. In recent years, space technology has made remarkable achievements in the development of spacecraft high-speed resources to acquire, transmit and forward information, and achieved great benefits, such as the wide application of communication satellites and remote sensing satellites.
On the other hand, with the rapid development of military spacecraft, various new space weapons such as military satellites, manned spacecraft, ballistic missiles and anti-ballistic missiles have formed an integrated space battlefield military system and will play an important role in joint campaigns. As we all know, without a solid national defense, our happy life is hard to guarantee.
Without today's investment, there will be no tomorrow for us. The progress of aerospace industry will drive the development of related industries, and the application of aerospace science and technology will have a great impact on mankind. Only with the continuous progress of society and the continuous development of science and technology will our life become more and more beautiful.

Following the successful launch of Tiangong-2 Space Laboratory in Jiuquan Satellite Launch Center on September 15, Shenzhou XI was successfully launched on September 10/7, and will automatically rendezvous and dock with Tiangong-2, opening the longest manned space flight in China. This is another breakthrough of China Aerospace!
This great progress in the field of space technology is not only substantial scientific progress, but also the embodiment of China's comprehensive national strength and scientific and technological strength.
70. Generations of astronauts have been striving for self-improvement, creating brilliant achievements represented by "two bombs and one satellite", manned space flight and lunar exploration project, and realizing the rapid development of space technology, space application and space science.
In the future, the dream of China astronauts continues to extend into space. The Shenzhou 11 manned spacecraft will dock with the Tiangong-2 Space Laboratory, the epoch-making Long March 5 heavy carrier rocket will fly for the first time, and new space science satellites such as hard-ray modulation telescope detection satellites are already in sight ... The universe is endless, exploration is endless, and the benefits to mankind are endless. China Aerospace is continuing to write new legends, gathering great strength for realizing the Chinese dream of the great rejuvenation of the Chinese nation and making greater contributions to enhancing human welfare.
The rapid development of space technology has achieved a comprehensive leap in space R&D, manufacturing and application capabilities, promoted a number of new technologies and their industrialization in the fields of information technology, microelectronics and new materials, and promoted the progress of economy, society and life. It shows the great spirit of China and the strength of China.
Looking to the future and standing at a new starting point towards the great rejuvenation of the nation, China Aerospace has embarked on a new journey of "accelerating the construction of a space power". It will take five to seven years to complete the existing major scientific and technological projects such as manned space flight, lunar exploration project, Beidou navigation and high-resolution earth observation system; Around 20__ years, the national civil space infrastructure will be built in an all-round way, and the scale, operation and industrialization of spatial information application will be promoted; In 2030, it will achieve a comprehensive leap and become one of the space powers.
It can be believed that the profound aerospace spirit and the rapid development of the aerospace industry will certainly inspire the enthusiasm of the whole nation for exploration and innovation, inspire the people of the whole country to work hard and vigorously promote the Chinese dream.

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 infinite 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.
Reflections on the Tiangong Classroom in 2022 5
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.
