Essays on feedback in Tiangong classroom (seven articles)

The Tiangong class has been broadcast. I believe that after reading it, the students are full of yearning for space, and at the same time they have planted the seeds of space dreams in their hearts! The following is an anthology (seven articles, I hope you like it) of feedback from Tiangong class.

1 Not only manned space flight, but also Chang 'e's lunar exploration, celestial fire exploration and Beidou navigation. China's space industry started late with a low starting point. Why is it still developing rapidly and with high skills?

Upholding the party's leadership is a magic weapon. Every breakthrough in key technology, every success in test flight and the completion of every arduous task embodies the decision-making and care of the CPC Central Committee, and the wisdom and strength of the party organizations in the aerospace system and the cadres and workers in party member. Behind the brilliant achievements of China's space industry is the decision-making and deployment of the CPC Central Committee, which regards scientific and technological self-reliance as the support of the national development strategy and guides the direction of the space industry.

The 19th National Congress of the Communist Party of China was grandly opened in Beijing. "Building a space power" was written into the report of the 19th National Congress, and China's space industry once again stood at a new historical starting point.

"The space dream is an important part of the dream of a strong country." General Secretary Xi Jinping said that it is our unremitting space dream to explore the vast universe, develop the space industry and build a space power. Developing manned space flight and building China's own space station is the only way to realize the space dream in the new era.

According to statistics, in the manned spaceflight project, there are hundreds of institutes and units directly involved, and thousands of cooperative units, involving hundreds of thousands of scientific research workers. "Without the centralized leadership of the CPC Central Committee and the strong cooperation of the whole country, it is unthinkable to carry out such a grand project of manned spaceflight." Zhou Jianping, chief designer of China's manned spaceflight project, said.

Draw a blueprint to the end and run one stick after another. At the manned space launch site more than 40 kilometers away from the Dongfanghong satellite launch tower, a new generation of astronauts are starting their journey to heaven by relay.

The conditions may not be so bitter, but the aerospace spirit is in the same strain. Someone once asked Nie Haisheng, who flew twice, and Jing Haipeng, who dreamed three times: "You have realized your dream of flying for a long time. Are you going to take such a big risk in the future? "

As the representative of the 19th National Congress of the Communist Party of China, Jing Haipeng gave such an "answer" to Chinese and foreign journalists:

"I am very eager to go to space again, be a pioneer again, win again, and let the vast space once again witness the absolute loyalty and infinite loyalty of a space warrior to the party and the people!"

"Space flight is our career and our life. In order to fly, as long as the motherland needs it, we are always ready to go to space! "

Comments on the composition of the Tiangong classroom 2 "Arrow of God" is on the string, and then seek the sky. Since ancient times, human beings have longed to explore the universe. The Goddess Chang'e flying to the moon, Tian Bu and Kuafu are exploring the universe day by day ... The ancient legend is the simple yearning of China people, but it confirms the rich association and wisdom of the Chinese nation. Looking back on the development of China's manned spaceflight project, China astronauts, with the ambition of serving the country by space, made unremitting efforts and made pioneering progress, and achieved a series of brilliant achievements, such as manned space shuttle, astronauts' disembarkation and space rendezvous and docking. They have embarked on a road of independent innovation with China characteristics and accumulated a profound and broad space spirit. This "leap" will constantly guide us to "break the sky of Wan Li and aim at the sea of stars", show the enterprising spirit of self-reliance and unwilling to be left behind by astronauts, condense the ardent expectations of Chinese sons and daughters, condense the hard work of astronauts day and night, and condense the surging power of the country and the nation in pursuit of scientific and technological progress.

Self-reliance and overcoming difficulties. Manned spaceflight project is the embodiment of a country's comprehensive national strength, and the development of manned spaceflight technology is of great and far-reaching significance for strengthening China's economic construction and national defense construction, enhancing its international status and enhancing national cohesion. The struggle of China's space industry is a process of self-reliance and overcoming difficulties. "China Creation" broke through the key core technology of independent intellectual property rights, promoted the great leap of China's space technology, and became a vivid epitome of China's deepening scientific and technological innovation. No difficulty can elude the heroic people of China, which is inseparable from the strong leadership of the China Production Party, the silent efforts of space science and technology workers, and the self-reliance and continuous struggle of hundreds of millions of China people.

Self-improvement, courage to climb the peak. Looking at the world today, a new round of scientific and technological revolution and industrial transformation is reconstructing the global development map and reshaping the global economic structure. All countries regard the enhancement of comprehensive national strength as the primary goal of development strategy deployment, and its core is the development of science and technology, among which aerospace technology is one of the important contents. Manned space flight is one of the most challenging high-tech fields in the world. The coverage is wide and the influence is deep, and the richness of application scenarios has exceeded people's imagination. The sons and daughters of China will break the bottleneck of key core technologies with the spirit of self-improvement and courage to climb the peak, and will surely create greater glories. China's space industry can achieve today's achievements, thanks to the unique institutional advantages, and countless astronauts have made unremitting efforts to advance wave after wave and achieved today's space science and technology achievements.

Independent innovation, pursuit of Excellence. The development and progress of science and technology cannot be separated from independent innovation. Since the reform and opening up, the CPC Central Committee and the State Council have attached great importance to the development of space technology. From "science and technology are the primary productive forces" to "innovation is the primary driving force for development", "independent innovation" has witnessed the development of space technology for decades, achieved a major leap forward, firmly grasped the initiative of space technology, helped China rank among the forefront of the world's scientific and technological development, and pushed China forward to a socialist modern country. At present, profound changes have taken place in the domestic and international environment. Whether it is to achieve high-quality economic development or to meet the people's growing needs for a better life, it needs the help of space technology. Only by adhering to the road of independent innovation with China characteristics can we constantly pursue Excellence in overcoming difficulties and grasp the initiative of competition and development.

Knowing each other far and near, Wan Li is still a neighbor. Tianhe is long, even though space is out of reach, the vast starry sky will always be an irreplaceable neighbor of the earth, and exploration will never end. This is an exciting stone carving. The three astronauts, with the sincerity and courage of 65.438+0.4 billion people in China, questioned the Milky Way and flew directly to the sky, living up to expectations. This means that the development of the world's space industry has reached a new milestone, and it has contributed China's wisdom, China's plan and China's strength to the peaceful use of space and the building of human destiny.

A great cause breeds a great spirit. In the great journey of climbing the peak of science and technology, a new generation of astronauts forged the manned space spirit with their unique lofty realm, tenacious will and outstanding wisdom. This is the spirit of being able to endure hardship, fight, tackle key problems, endure hardship, fight, tackle key problems and contribute. These spirits are always worth learning.

Efforts in life are always beautiful. The road of life cannot be smooth forever. Everyone will encounter difficulties and setbacks in one way or another. We must rise up in setbacks and difficulties. This requires a fighting spirit, especially a fighting spirit, a particularly capable spirit. "If you eat hard, you are a master." The spirit of hard work in learning is always beautiful!

Unity is strength, the foundation of running a country and running a school. Imagine, if a collective is not United internally and there are still differences, will it be strong? More than that, some people who are trying to sabotage are attacking vigorously at this time, and the losses are even more unimaginable.

Both science and humanities. Since childhood, this old saying has been echoing in our ears: love science, learn science, and use science. However, how many people have actually implemented it? Friends think that as long as you learn to be a man and have cultural knowledge, you don't have to learn any science. Advanced science and technology are essential for a powerful country. As the "flower" of the motherland, we should not only develop science and humanities, but also retain norms and individuality!

Hard conditions have tempered the astronauts' spirit of special hard work. The aerospace industry started under extremely difficult conditions. In order to realize the dream of flying at an early date, the vast number of space workers have worked tirelessly, weathered hardships, overcome many difficulties and made great sacrifices. The severe challenges cast the astronauts' spirit of being particularly capable of fighting, and the lofty mission endowed them with the spirit of being particularly capable of tackling key problems. We teenagers should work harder and study harder. In life and study, when encountering difficulties and setbacks, don't run away, don't shrink back, advance despite difficulties, forge ahead and dare to win. Some students, when they encounter a little setback in life, lose confidence and hope in life and feel that nothing is good in the world. So, I committed suicide and hated leaving this world. You know, the world is beautiful. We should cherish life and enjoy this beautiful life. Even if it is not good, it is an unchangeable fact. Just like astronauts have to train in a harsh environment, that harsh environment is an unchangeable fact, so we have to change ourselves and break through this difficulty. Therefore, we can't give up our mission because of a little setback, but grow up in the environment, in hardships and difficulties, and achieve our life and mission. The same is true in learning. Learning depends not on cleverness, but on hard work. Study hard, study hard, and study hard unremittingly, which is a beautiful expression of the spirit of studying hard forever.

Unity and struggle have cultivated the dedication of astronauts. China's manned spaceflight project is a large-scale space system project. Regardless of the front and rear, regardless of fame and fortune, the vast number of astronauts perform their duties, stick to their posts, and form a strong synergy. We all live in the same big collective, and we all aim at the same goal-protecting the collective. Be indifferent to fame and fortune, regardless of personal gains and losses, be willing to Fengxian, unite as one, and create brilliance together. "Unity is strength", which is a powerful force and a force to push people forward. With this strength, we can overcome all difficulties, go forward bravely and achieve our goals. All human beings and countries in the world, small to class groups and families, should unite.

Science is an important symbol of a country's development and progress. As teenagers in the 2 1 century, we must learn science well, love science and use it. Both science and humanities need us to hold high at the same time. A standardized student is the demand of the motherland and a person who will make great achievements in the future. Putting science and humanities together, keeping norms and individuality * * * is a word to be wary of students.

In ancient times, people always wanted to send 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.

Space science and technology has always been a new field that any country must attach importance to, and it plays a very important role in our exploration of space and unknown fields. In today's society, air supremacy has become very popular, and then the deeper level is the space right. For example, the United States, a powerful country, took the lead in landing on the moon, and then he joined forces with other countries to divide areas on the moon, saying that whoever owns it will have the right to mine in the future, so our space technology cannot fall behind, otherwise we will gradually fall behind in the future 100, so space technology and space hobbies will be the most important direction of our new generation.

The first time I came into contact with space knowledge was in the kindergarten class. That day, the teacher posted a newspaper on the wall with a rocket-actually Shenzhou VI and two people-actually Fei and Nie Haisheng. After hearing the vivid explanation from the teacher, I figured it out and felt proud. Suddenly, I found-not a woman. At that time, I thought: If only I could become the first female astronaut in China! From then on, I went to primary school with such a dream. I once proudly told a classmate in my class that I would be the first female astronaut in China. He listened with envy. I was so proud that I thought it was too easy to be an astronaut! When I was in the third grade, I gradually learned something about aerospace. Only then did I know that being an astronaut was not that simple. Not only need to study, but also need good health and good psychological quality. In fact, I didn't understand what psychological quality was at that time, but I just vaguely felt that it was a good part of my body.

Although I know it is unrealistic for me to become an astronaut, I can work for them underground, such as ground service and research. We can study some safer and more efficient spacecraft or space equipment on the ground, and we can also move around in the underground command center and the middle space astronauts to see their vital signs and various information security technologies. Therefore, in order to realize this dream, I am constantly studying and attending some science and technology exhibitions. In order to know more about this knowledge and pave the way for my future dreams.

Tiangong Classroom Composition 6 Comments 202165438+There is good news on February 2nd! China Manned Space Engineering Office announced that in order to give full play to the comprehensive benefits of China Space Station, China's first space science education brand "Tiangong Classroom" will be officially launched, and the first space teaching activity of China Space Station will be broadcast live to the whole world in the near future.

I am very excited to see this news, because I can see a series of wonderful phenomena of object movement in space microgravity environment. This reminds me of the 20 13 space lecture.

In just 40 minutes, the astronauts only used five simple experiments to let everyone know more about the changes of objects and their principles in weightlessness. There are also water film experiments and gyro experiments, which let me know that I can do many incredible things in weightlessness, among which water polo experiment is the one I am most interested in! First, put a ring about the size of a magnifying glass into a drinking tap water bag, and it will become a water film after taking it out. Then, water drops will be continuously injected into it, and slowly the water film will become a crystal clear water ball. If you insert the needle into the water polo on the ground, it goes without saying that the water polo will explode. However, it is a miracle that we can inject ink into the water polo with a needle in space, but the water polo is "unscathed"! This made the audience dumbfounded.

Armstrong, the first man to land on the moon, once said: One small step for me, one giant step for mankind. Although we can only watch space lectures on TV screens thousands of miles away now, I believe that one day we can go to space in person, communicate face to face with lecturers and feel the fun of space.

I like the beautiful Chinese knot hanging on the Tiangong space station, facing the bright five-star red flag. Such a space station is the most beautiful scenery in space, and it also makes us feel more cordial.

In space, you should control your body to adapt to weightlessness and swim around like a fish. Food was originally prepared in advance on earth. Cultivating space plants is an important task in this mission. In space, although you can't take a hot bath like on earth, there is no problem in washing your face and hair. Researchers have specially developed a decomposition shampoo-it can not only wash your hair clean, but also save water. The water in the space station is very precious, so we should save water as much as possible.

Sleeping in the space station is more interesting. As long as you have a sleeping bag, it is generally required to be fixed on the bulkhead, but you can sleep anywhere, such as the ceiling, as long as you like. There are also many leisure activities in the space station, such as video calling with family members, enjoying the beautiful earth at sunset from the porthole and doing morning exercises. Morning exercise is a traditional fitness program in China-Tai Ji Chuan.

The most important and exciting thing is extravehicular activity. Put on your "flight suit" and go outside the cabin through the airlock. Through the joint efforts of the ground dispatcher and the cabin companions, the related tasks were successfully completed outside the cabin.

There are also many happy events in space: the rice planted is heading, the space courier is ushered in, and new partners are ushered in for work handover. After staying in space for three months, I will bid farewell to the Tiangong space station and return to Earth soon. I am very excited to meet my relatives on earth soon.

Space itself is fascinating. In the vast universe, every time there is a five-star red flag, every Chinese son and daughter feels cordial and proud!
