Reflections on the Second Space Classroom 2022 (6 articles)

As a national space laboratory, China Space Station is also an important space science education base, which contains rich educational resources. I'd like to share some model essays about the second space class with you, hoping to help you.

Reflections on the second space class 1

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.

Reflection on the second space and the second classroom

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.

Thinking about the Second Space Lesson 3

This is a great moment. Shenzhou 13 is a famous expedition, composed of astronauts from China, who flew into the dream sky in droves, attracting the attention of the whole world. Rejuvenating the country through science and technology, and building a dream through space have placed the ardent expectations of hundreds of millions of people in China and carried the grand pursuit of the Chinese nation's prosperity. Shenzhou spaceship once again set sail, breaking through the sky, showing the Chinese nation's spiritual character of endless life, courage to climb the peak, pioneering and innovative, and striving for progress.

The space dream illuminates China's road to rejuvenating the country through science and technology. Global concern, the world looks up; The starry sky is bright and Shenzhou shines. Science and technology lead, Shenzhou flies, and China's space spirit is a spiritual portrayal of overcoming difficulties, innovating and creating, and not seeking ease and hardship, which illuminates the road of rejuvenating China through science and technology. In 2003, China's first astronaut, Yang Liwei, flew into space in a manned spaceship in Shenzhou 5, realizing his dream of flying for thousands of years. Today, the Shenzhou 13 manned spacecraft carried three astronauts into the space station for a three-month work, verifying the functional performance of the manned space shuttle transportation system, verifying the astronauts' long-term stay support technology, verifying the astronauts' ability to complete extravehicular activities and operations together with the robotic arm, and testing the search and recovery ability of the Dongfeng landing site. Shenzhou XIII will successfully complete all the established goals and major tasks, arouse the dream of the Chinese nation in the boundless starry sky, hold high the dazzling five-star red flag, highlight the bloodline of the Chinese nation's inheritance and pursuit of ideals from generation to generation, and play a strong cosmic voice for the Chinese nation's great dream of rejuvenation.

Revive dreams and light up the road to China's all-round rejuvenation. Standing at the historical intersection of the goal of "two hundred years" and the first year of the 14 th Five-Year Plan, with the Shenzhou expedition as the symbol and guidance, the Chinese nation will certainly be able to create a new bureau and create a more brilliant future. The spirit of space flight, Jinggangshan spirit, Long March spirit, Yan 'an spirit, Anti-Japanese War spirit and the spirit of tackling poverty have gathered the spiritual pedigree of the Chinese nation, inspiring the cadres and masses in party member to make contributions, continue to struggle and be determined. The dream of the great rejuvenation of the Chinese nation will come true step by step with our efforts and become an eternal miracle in history.

The Chinese dream illuminates the prosperity of China. The Chinese dream is a great dream to achieve national prosperity, national rejuvenation and people's happiness. Building a socialist market economy, socialist democratic politics, advanced socialist culture, socialist harmonious society and socialist ecological civilization, consolidating national defense and a strong army, building a learning, service-oriented and innovative Marxist ruling party, realizing the reunification of the motherland and promoting the construction of a harmonious world constitute the overall outline of the Chinese dream. To realize the Chinese dream, people fully enjoy economic, political, cultural, social and ecological rights, and become richer, more equal, happier, more free and safer. People yearn for the Chinese dream, which is the ideal and belief of the 65.438+0.4 billion people in China, their dream of happiness and the highest banner that unites all the people in China. People of all ethnic groups in China have dreams in their hearts and roads under their feet. If they are down-to-earth and work hard, they will be able to gather powerful and majestic forces with the wisdom and strength of 654.38+0.4 billion people. All producers in party member, especially leading cadres, should strengthen their ideals and beliefs, carry forward the glorious tradition and fine style of work of the Party, listen to people's voices, respond to people's expectations, keep the political qualities of * * * producers forever, and lead the people in their struggle to realize the Chinese dream.

"Great undertakings are based on innovation" and "Great undertakings are based on hard work". The Chinese nation's long-standing yearning for the universe will eventually write an irreplaceable wonderful stroke in the starry sky. This is a great expedition, which embodies the dream of hundreds of millions of Chinese sons and daughters to become a space power and further enhances the self-confidence and pride of the Chinese nation.

Thinking about the Second Space Lesson Four

At 10 and 16: 23 Beijing time, the Long March II F-13 carrier rocket carrying the Shenzhou XIII 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 predetermined orbit, and three astronauts, Zhai Zhigang, Wang Yaping and Ye Guangfu, were successfully sent into space. The pilot was in good condition and the launch was a complete success.

The exploration of the universe is endless, and China music plays in space. Every Shenzhou launch is always exciting and is the pride of the motherland. Every space exploration is always inspiring and praising the times. The launch of Shenzhou XIII manned spacecraft was a complete success, and the new "Space Business Journey" trio set sail beautifully. We cheered. The vast starry sky will make new contributions, and space exploration will write another chapter. China is wonderful!

The dream of flying is magnificent, and the music is always loud. Every Shenzhou launch will bring us many "firsts" symphonies-the manned spacecraft will dock at the space station for the first time in a radial way by autonomous rapid rendezvous and docking; Astronauts will stay in orbit for the first time for six months; Female astronauts will be stationed in China Space Station for the first time, and astronaut Wang Yaping will also become the first female astronaut in China to carry out extravehicular activities. The crew of Shenzhou XIII will also include male and female astronauts who left China for the first time; China people will spend the Spring Festival in space for the first time; Wait a minute. Every "first time" is the result of scientific and technological exploration and innovation, and every "first time" is the crystallization of China's wisdom and China's strength. It was in these "firsts" that China's space industry swaggered and China's great rejuvenation was successful.

The mission is glorious and the task is heavier. Every space exploration is a great note of a magnificent cause, a summary, a sublimation, and a cohesive force to a higher level. The on-orbit construction of China Space Station is divided into two stages: key technology verification and construction. Shenzhou XIII mission is the decisive battle and final battle in the key technology verification stage of the space station, and it is also the key battle to link the past with the future in the on-orbit construction of the space station. Through the Shenzhou 13 mission, the functional performance, matching and coordination between engineering systems performing the space station mission will be evaluated more comprehensively. After the Shenzhou XIII mission, a comprehensive system-wide assessment will be organized, and it will be transferred to the construction stage of the space station after meeting the requirements. Therefore, its mission is significant and far-reaching.

Exploring the sea of stars, the trip to China is magnificent. A brand-new trio of "Space Travel", a perfect combination of "Old, Middle and Young", has written a perfect space record for China. A song "Dongfanghong" resounded around the world, "two bombs and one satellite" attracted worldwide attention, and "manned space flight" became an instant hit. "Chang 'e" flew to the moon, "Beidou" showed the way, "Tian Wen" asked the sky, "Tiangong" won, "Jade Rabbit" explored the moon, "Zhu Rong" explored the fire, "xi He" explored the sun ... It was a beautiful legend and a miracle that one person went to three people in half a year. Nine dreams ask for heaven, striding to strengthen the country. Spend nine days on the moon and see the palaces in the sky. This is the common memory of the country and the nation, and this is a magnificent poem of national development.

The vast starry sky has made new contributions, and space exploration has written a chapter. China's manned space flight spirit is great, and the "Tianhe" exploration journey is beautiful. Astronaut Wang Yaping said, 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! Zhao, spokesman of the Ministry of Foreign Affairs of China, said: We look forward to hearing the blessings from our compatriots in space as soon as we celebrate the New Year's Eve. If you don't stop, the future can be expected Shenzhou XIII mission shows China's new efforts and contributions in manned space exploration. China will certainly make positive contributions to the exploration of the mysteries of the universe, the peaceful use of space, and the construction of the same body of human destiny.

Reflections on the Second Space Lesson 5

I like the beautiful Chinese knot hanging in 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 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!

Reflections on the Second Space Lesson 6

A "space lecture" 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 solve, but ultimately serves scientific life, which is very beneficial to cultivating 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" are widely planted to serve human life, and space science and technology have contributed greatly.

The fourth is the influence on interesting education. I believe that after watching this lecture in space, even students who are unwilling to learn scientific knowledge will find science 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 have more fun, intuition and vividness like "teaching in space" in our usual educational activities, we can not only learn scientific knowledge from boring to interesting.

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 "space lecture", we know that the space seen by astronauts is a very bright black sky, and technology will always be a magic weapon for a country to be invincible. Space technology is not only powerful, but also related to the scientific and happy life of our family. The Chinese dream is down-to-earth, and the technological dream has unlimited tension!
