Comments on Tiangong Classroom 1

More than 6 years ago, China's space industry officially started, and the success of every space launch mission is a true manifestation of China's continuous efforts and struggles. In the future, with the continuous development of the new generation of Long March series launch vehicles, China's launch vehicle capability will once again achieve a new leap: a new generation of medium-sized launch vehicles such as Long March 6A, Long March 7A and Long March 8A are being developed as planned to realize the "upgrading" of the launch vehicles as a whole; The Long March 5 rocket will carry out several important launch missions successively, supporting the steady implementation of major engineering projects such as the lunar sampling return in the third phase of China's lunar exploration, the launch of the Mars probe in 22, and the construction of the core cabin of the space station; The heavy launch vehicle is expected to make its first flight in 23, which will make China's space transportation system level and capability enter the forefront of the world's space powers ...

At the same time, China's space transportation mode will also achieve major breakthroughs from one-time use to repeated use, from single space transportation to the combination of space transportation and space operation. It is not difficult to imagine that with the continuous enhancement of China's space comprehensive strength, the Long March series of launch vehicles will surely carry China's space dream, condense the struggle spirit of China astronauts, fly into space again and again, and start the "New Long March" of China's space industry. Looking up at the stars, the journey is long. 3 launches are only the first step of the "Long March" of China's space industry, and there are 5, 1, or even more breakthroughs waiting for us to make unremitting efforts.

I believe that in the future, we will be able to create more space miracles, realize a new and bigger "space dream" and leave a more wonderful China mark in the vast universe.

Reflections on the Tiangong Classroom 2

At : 23 on October 16, 221, the Long March II F-13 carrier rocket carrying the Shenzhou 13 manned spacecraft was accurately ignited and launched at Jiuquan Satellite Launch Center according to the scheduled time. About 582 seconds later, the Shenzhou 13 manned spacecraft was successfully separated from the rocket and entered the scheduled orbit, and three astronauts, Zhai Zhigang, Wang Yaping and Ye Guangfu, were successfully sent into space to fly.

It's dawn, good news comes, people are excited, Shenzhou XIII is successfully launched, three space heroes are sent into space, and they will dock with the Heavenly Palace and start a six-month journey. China's space industry has reached a new level.

Chairman Mao's grand plan of "going to the moon for nine days" is no longer a dream. Space industry, the peak of science and technology, group warfare, unity of mind to show national strength, lead the future, and make life. It consumes a lot of manpower, material resources and financial resources, but focusing on the future is a far-reaching plan, which is related to the national economy and people's livelihood. You can't have a happy dream unless you work hard. If my husband is confined to a small family, what does space flight have to do with me? I am indifferent and blame the waste of people and money. It is really foolish. No, space industry, people and * * *. One is related to the overall situation of mankind, the height of development, showing national strength and attracting respect. Both of them are of great benefit to space exploration, scientific research and the benefit of the people. The three are related to national security. Only by seizing the commanding heights of science and technology can we not be controlled by others, which is the true guarantee of peace. Therefore, scientific research can be carried out internally to benefit the people with achievements and enhance national self-confidence with honor. We can serve everyone, improve safety and promote human beings to win. If so, it is the mission of the space industry.

from here to there, exploring endlessly, going to heaven and going to earth, is the hero of the country. The times call for heroes, and only by respecting heroes can national rejuvenation be achieved. Space hero, reposing the dreams of hundreds of millions of people, dare to take responsibility, be a pioneer, be a model of the times, and be the spring breeze of Chinese people. National rejuvenation begins with children. Aerospace edifies, ignites dreams, goes to the impetuous entertainment, and also has noble beliefs; Aim high, and get rid of the mediocrity of material desires. If so, teenagers have dreams, ideal original intention, non-exquisite self-interest, non-profit moth, which is the hope and light of the nation.

attach importance to science and technology, respect heroes, cultivate new styles and benefit the people. If so, it is the continuation of the spirit of the Long March, the inheritance of the spirit of two bombs and one satellite, the hope of the nation and the rejuvenation of China. Fan Zhongyan's famous sentence: worry about the world first, and then enjoy the world. Gu Yanwu Ceng Yun: Every man is responsible for the rise and fall of the world. Lin Zexu's poem says: It's selfish for the country to live and die, so don't avoid it because of misfortune and happiness. And so on, is the wind of national culture.

the aerospace industry is beneficial to the present and the future, which is related to everyone and benefits everyone. Therefore, it can be seen that the original intention of the aerospace industry is to travel backwards, ignite dreams, live up to the mission and benefit the people. Do not forget your initiative mind, remember the mission and help the national rejuvenation. Pay tribute to the space hero, spend nine days on the moon and travel in space. Focusing on the future of mankind is for the pattern; Based on national strength, it is pragmatic; Carrying forward the spirit of exploring and asking for heaven is for faith; Taking space as the stage, scientific research will yield a bumper harvest and benefit the people, which is for the fruit. In this way, if we have a strategic height and a noble mission, we will know that everyone is responsible, the country and * * *.

Therefore, we know that the universe is home, and it is a naive hero in the world. The brave are fearless, and great love benefits the whole life. Rebuild faith and national rejuvenation. As the saying goes: people who have no country and courage have no roots, and people have the dream of being a country.

Thoughts on Tiangong Classroom 3

The Shenzhou XIII manned spacecraft will be launched in the early morning of October 16th. In response, Zhao Lijian, a spokesman for the Ministry of Foreign Affairs of China, said on the 15th that less than a month ago, China welcomed the triumphant triumph of the Shenzhou-12 manned spacecraft. In the early morning of the 16th, China will once again watch Shenzhou-13 fly into space with excitement. "This not only vividly interprets China's manned space spirit, which is particularly hard-working, especially capable of fighting, especially tackling key problems, and especially dedicated, but also embodies the spirit of scientific exploration of China people who dare to pursue their dreams, dare to explore and never stop."

At the regular press conference of the Ministry of Foreign Affairs held on the same day, Zhao Lijian insisted that on the 15th, the press conference of the Shenzhou-13 manned mission was held in Jiuquan Satellite Launch Center, and a spokesman for China's manned spaceflight project introduced the relevant information. The Shenzhou-13 manned mission was the key technology verification stage of China's space station, and the sixth mission was the decisive battle and the final battle at this stage, and it was also the key battle to link the past with the future in the on-orbit construction of the space station.

"What I want to say is that the Shenzhou XIII mission shows China's new efforts and contributions to manned space exploration. China will continue to increase the depth and breadth of international cooperation and exchanges in the field of manned spaceflight, and make positive contributions to mankind's exploration of the mysteries of the universe, the peaceful use of space, and the promotion of the construction of the same body of human destiny. " He said.

Zhao Lijian insists that it can be noticed that there are many differences in the group work arrangement between the Shenzhou 13 mission and the Shenzhou 12 mission, including that China female astronauts will be stationed in the China Space Station for the first time and carry out extravehicular activities, China astronauts will stay in orbit for the first time for six months, and China people will spend the Spring Festival in space for the first time. "We look forward to hearing our compatriots' blessings from space on New Year's Eve. Let's wish the Shenzhou 13 manned spacecraft a successful launch."

Afterthoughts on Tiangong Classroom 4

"Persistence because of love, persistence because of dreams", this is the words of astronaut Wang Yaping who carried out the Shenzhou XIII mission. Every underwater training for the space station mission, physical energy consumption is equivalent to running a "full horse", so tired that they can't even hold chopsticks stably, but they are tired and happy. Every centrifuge training has to bear up to 8 g overload, and the face will be deformed and the chest will be difficult to breathe due to pressure. However, since the establishment of the Astronaut Brigade for more than 2 years, no one has ever pressed the "pause button". This kind of body can be "overloaded", and faith and spirit are always "lightly loaded", which explains a belief and a will. The spirit of revolutionary optimism and revolutionary heroism has penetrated through time and space in today's China astronauts, giving off a powerful force that is shocking and breathtaking.

it seems to be the most extraordinary, but it is easy but hard to achieve. A country or a nation can climb whatever altitude it has spiritually. Although we can't leave our footprints in the vast firmament like the astronauts of Shenzhou XIII, we can vigorously carry forward the national spirit with patriotism as the core on the new Long March, be willing to be a "willing ox", be a "pioneering ox" and often be an "old ox" in all walks of life built in the motherland, and constantly make calcium and steel with the spirit of patriotism and manned spaceflight, and always keep "the more difficult it is, the more forward it will be". 4-word composition on the reflection of Tiangong Classroom 2

The reflection of Tiangong Classroom 1

Today, I watched the program of Tiangong Classroom, which made me learn a lot of knowledge.

In 213, Wang Yaping, a Chinese astronaut, really gave his first lecture in the sky. After a lapse of eight years, today's technology is very different from that of the past. Moreover, the quantity and quality of cameras have improved this time, which has also caused great pressure on astronauts. And she will hold a camera in her hand, which is no easier than holding it on land.

Mr. Zhang asked us several questions. In the space station, what are the directions of cubic six-sided sowing, roots and buds? The answer is that the roots spread into the soil and the buds grow back to the planting surface and face the light. Because the earth has gravity, the roots of plants on the earth grow underground, while in the microgravity environment in space, their roots will grow everywhere, and their roots will bend and grow in the soil.

second question, what happens when you pour water from a teapot into a cup? The answer is that the water is in the teapot and can't be poured out. In a light environment, water will float on it, and it is impossible to pour water.

third question, can goldfish swim in the open fish tank in the space station? No, because water and fish are separated, and the water will swim for a while in a short time, and then they will separate.

The astronauts are on the extravehicular manipulator, holding a small steel ball in one hand and a feather in the other, and throwing them in the same direction with the same force in both hands. The scheduled distance is two meters. Who will arrive first? The answer is feathers. In vacuum microgravity, the mass is small and the acceleration is large, so the feathers arrive first.

After that, I learned some wonderful moments in space flight. After that, I visited some astronauts' "space homes" and learned about some equipment in space.

I also learned that on the ground, table tennis floats on the water, while in space, table tennis is immersed in water. In the space station, buoyancy almost disappeared. A water film, and after adding water to the water film, put an artificial flower in the water film, and the flower becomes bigger in the air, just like blooming. After continuing to inject water into the water film, the water film will become a water ball. Inject a bubble into the water polo, and a positive image and a negative image are formed in the water polo. Inject the pigment into the water polo, and then put the effervescent tablets into the water polo. After that, a lot of bubbles will be generated in the water polo, and the water polo looks more beautiful.

after this experiment, I learned a lot from this sky lecture, and I like this sky lecture very much.

Reflections on the Tiangong Classroom 2

On December 9th this year, today, our country implemented the Tiangong teaching that even Americans did not practice. It's really an amazing attempt! Three astronauts of Shenzhou 13, Zhai Zhigang, Wang Yaping and Ye Guangfu, showed a series of space scenes to people all over the world, which once again made China people further in the space field and greatly enhanced China's international strength!

The astronauts became teachers and told us about the life of the space station. Because of the weightlessness of astronauts in space, walking, turning around and other things that seem very simple to us have become a big problem in space. However, the astronauts can ensure their health from various instruments, which once again powerfully illustrates the strength of contemporary China, and the language of space experiments is different on earth. For example, the water in space loses its buoyancy and becomes a liquid-like thing. When the astronauts put an instrument into the water, the water immediately formed a water film. Adding air inward will also become a double lens, one positive and one negative. When effervescent tablets are put into water. The generated bubbles will expand in the water film, but will not leak out. These experiments are really interesting. They not only popularize space knowledge, but also show the world the strength of China.

watching this moment, I feel deeply. Think that China was just a piece of "fat meat" in the eyes of the invaders, and there was a crisis of national subjugation and extinction at any time. However, the people of China are determined to forge ahead. In order to realize the great rejuvenation of the Chinese nation, the people of China have regained their national dignity in one war after another, and achieved a leap of standing up and standing up completely! Only by creating a glorious nation can we understand the significance of rejuvenation. Today, China has become the largest country in the world, changed its international status and stood proudly among the nations in the world!

The future motherland needs us, and we need to work harder.

Looking forward to, looking forward to, "Tiangong Classroom" will finally meet with us. The program moved the classroom to China people's own space station, and three astronauts in the space core cabin brought us a special "space lecture".

I want to be a people's teacher when I grow up, because now my classmates have too much homework, and they cry silently because of their homework where their parents can't see them. It is said that people have three sufferings: studying, driving horses and grinding bean curd. Now reading is more bitter than before, so in the future, I want my classmates to really "lighten the burden" and let the flowers of the motherland smile more brightly.

In spring, I will take them out for a spring outing, enjoy flowers and play games. In summer, we sit under the tree and have a heart-to-heart talk. In autumn, let's go to see how the leaves fall. In winter, we have snowball fights and make snowmen together.

Students, ideals are not dreams. We need to take practical actions. Come on, let's create a better tomorrow together!

Reflections on the Tiangong class 4

I like the beautiful Chinese knot hanging on the Tiangong space station, which is 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 the feeling of weightlessness and swim around like a fish. The food was originally prepared in advance on earth. Cultivating space plants is an important task in the mission.

in space, although you can't take a hot bath like on earth, you can wash your face and hair. Researchers have specially developed a decomposition shampoo-it can not only wash your hair very 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 even more interesting. As long as a sleeping bag is ok, sleeping bags usually need
