Space station 1 tiangong classroom lesson 2
I learned a lot after watching the program "Tiangong Classroom".
In 20 13, China astronaut Wang Yaping really gave his first lecture in the sky, but eight years later, today's technology is very different from 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 the camera in her hand, which is no easier than holding it on land.
Teacher Zhang asked us a few questions. In the space station, the cube is sown on six sides. What are the directions of roots and buds? The answer is that the roots spread into the soil and the buds grow back to the planting surface, facing the sun. Because of the gravity of the earth, the roots of plants on the earth grow underground, but in the microgravity environment of space, their roots will grow everywhere, and their roots will bend and grow in the soil.
The second question is, what will happen if the water in the teapot is poured into the cup? The answer is that the water is in the teapot and can't be poured out. In light environment, water will float on it, so it is impossible to pour water.
The third question, can goldfish swim in the open fish tank of the space station? No, because water and fish are separated, and the water will swim for a while in a short time and then separate.
On the mechanical arm outside the cabin, the astronaut holds a small steel ball in one hand and a feather in the other, and throws it in the same direction with the same force in both hands. The predetermined distance is two meters. Who will arrive first? The answer is feathers. In vacuum microgravity, the mass is small, the acceleration is large, and the feathers arrive first.
After that, I learned some wonderful moments of space flight. After that, I visited the "space home" of some astronauts 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. On the space station, buoyancy almost disappeared. A water film, 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, then put the effervescent tablets into the water polo. After that, there will be many bubbles 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.
The bright five-star red flag flying in the space station is the most beautiful scenery in space, which makes us feel more cordial. Astronauts have overcome countless difficulties, and the harsh challenges have cast the astronauts' spirit of being particularly capable of fighting. The lofty mission has revived the astronauts' spirit of being particularly capable of tackling key problems. As primary school students in the new era, we should learn from this spirit of astronauts, work harder and study harder. When you encounter difficulties and setbacks in life, don't shrink back and go forward bravely.
Lessons from the second lesson of "Tiangong Classroom" in Space Station No.2
"Flying dreams never lose weight, and scientific dreams have unlimited tension." Eight years ago, "space teacher" Wang Yaping gave a lesson to more than 60 million students in China. Now she is once again on a trip to space, becoming the first female astronaut in China and the first female astronaut in China. Looking at the sound, the mysterious and distant deep space is getting closer and closer to us, and the beautiful "flying dream" is becoming a reality.
/kloc-in the early morning of 0/6, Shenzhou XIII was successfully launched, less than a month after the successful return of the Shenzhou XII manned spacecraft. A new "space travel trio" composed of Zhai Zhigang, Wang Yaping and Ye Guangfu went to China Space Station by manned spacecraft. This mission will achieve a number of "firsts" such as radial rendezvous and docking with the core cabin, transfer from a rescue ship to a formal mission ship, and will carry out more space science experiments and technical experiments on the basis of the Shenzhou 12 mission.
"Sit on the floor, travel 80,000 miles a day, and look at thousands of rivers." In 2003, the Shenzhou 5 spacecraft was launched with Yang Liwei at Jiuquan Satellite Launch Center, and it took 2 1 hour and 23 minutes to successfully return to the ground, realizing the Chinese nation's dream of flying for the first time. Since 18, there have been seven manned flights, with the interval from to. The frequency of "business trip" is faster, the contact is smoother and the preparation is more leisurely, which shows China's ability to stand on its own feet in science and technology. From "one-day tour" to "seasonal tour" to "in-depth tour" lasting for half a year, the "space business trip" takes longer, takes bigger, farther and firmer steps, and shows the self-confidence and pride of a big country.
From "Two Bombs and One Satellite" and "the Goddess Chang'e flying to the moon" to "Beidou" to guide the way, "Tiangong" to range rover and "Tian Wen" to explore the fire, and then to "Shenzhou" series to roam the sky, "xi He" to chase the sun ... Breakthrough again and again, step by step, the Chinese nation's exploration of space extends from the moon and Mars to the sun; As far as China people's eyes are concerned, they are looking up at the bright starry sky, searching for dark matter and gravitational waves, and even deeper unknown areas in space.
"The romance of China astronauts is to turn myths into reality". Indeed, in the vast space, more and more China space figures are composing the romantic feelings of the Chinese nation for the vast starry sky into realistic poems to explore space. According to the arrangement, the astronauts of Shenzhou XIII will stay in orbit for six months, and China people will spend the Spring Festival in space for the first time. Looking forward to the New Year's Eve, I can hear the blessings of my compatriots from space for the first time.
Lessons from the second lesson of "Tiangong Classroom" on Space Station No.3
Shenzhou XIII manned spacecraft was launched in June 16 and 18, and the flight crew consisted of three astronauts, namely Zhai Zhigang, Wang Yaping and Ye Guangfu. It was only a short month from the return of Shenzhou 12 to the launch of Shenzhou 13 in September 17. According to the plan, after the Shenzhou XIII spacecraft enters the orbit, it will dock at the radial port of Tianhe core cabin by autonomous rapid rendezvous and docking, and form an assembly with Tianhe core cabin, Tianzhou-2 and Tianzhou-3 cargo spacecraft. Astronauts will be stationed in the core cabin and work and live in accordance with the synchronous work and rest system of heaven and earth for up to 6 months. This means that compared with Shenzhou 12, the space challenge is longer, more difficult and more demanding. Astronauts will celebrate the Lunar New Year with us in space.
You can spend nine days on the moon, catch turtles in five oceans, and laugh and laugh. Man's yearning for and exploration of space has never stopped. However, in space, the vast sky seems magnificent and vast, but in fact it challenges the psychological and physical limits of astronauts and experiences many thrilling moments. According to astronaut Yang Liwei's recollection, during the mission of "Shenzhou 5", the rocket unexpectedly appeared a low-frequency vibration of about 8 Hz in the ascending phase, which had a * * * vibration with human internal organs for 26 seconds. At this point, Yang Liwei felt that his internal organs seemed to be broken and extremely painful, but he still gritted his teeth and told himself to "hold on, hold on again". In fact, this 26-second * * vibration is only a small microcosm of the hardships of China's manned space flight, but it outlines a "patriotic group portrait" of China astronauts who are brave and fearless and died for their country.
In the three months since Shenzhou XII left the earth, three China astronauts who were radiant in the eyes of outsiders all came from ordinary and simple families. When they are far away from the earth, cruising around the world and working hard, the villagers who stay in their hometown are working hard year after year as always. The dedication and responsibility of China astronauts began with blood, faith and patriotism. They carved their mission and burden on their shoulders and dedicated their honor and aura to the motherland and the nation.
"Persist because of love, persist because of dreams", this is the words of astronaut Wang Yaping who carried out the Shenzhou XIII mission. Every time you train underwater for the space station mission, your physical energy consumption is equivalent to running a "full horse". They are too tired to hold chopsticks steadily, but they are tired and happy. Every centrifuge training has to bear an overload of up to 8 g, the face will be deformed due to pressure, and the chest will have difficulty breathing due to pressure. However, since the establishment of the Astronaut Brigade for more than 20 years, no one has ever pressed the "pause button". This kind of body can be "overloaded", and faith and spirit always "go into battle lightly", which shows a belief and a will. The spirit of revolutionary optimism and revolutionary heroism, in today's China astronauts, through time and space, exudes a powerful force that is shocking and breathtaking.
It seems to be the most extraordinary, but in fact it is easy and difficult. A country or a nation can climb as high as it is spiritually. Although we can't leave our footprints in the vast sky 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 cow", "a pioneer cow" and always be an "old ox" in all walks of life in the construction of the motherland, and constantly supplement calcium and steelmaking with patriotism and manned spaceflight spirit, and always keep "the more difficult it is, the more brave it is".
Lesson 2 Experience of Tiangong Classroom No.4 in Space Station
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 Chinese 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.
Experience of the Second Class in Tiangong Classroom No.5 of Space Station
This is a great moment. With the glorious launch of Shenzhou XIII, the flying crew composed of China astronauts pursued their dreams and attracted worldwide attention. 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.
