Review and understanding of 2022 lectures by space experts in primary and secondary schools 1
Memories 2011At 9 o'clock on September 29th, I sat in front of the TV and witnessed the launch of Tiangong-1. That inspiring moment is of great significance to the Chinese nation, and I can't help feeling.
The successful launch of Tiangong-1 means the launch of China's first self-developed manned space test platform. Looking back at the whole history of China's space flight, Qian Xuesen first proposed that a series of satellite spacecraft such as "Dongfanghong-1" and "Shenzhou 5" appeared one after another in February 1956, showing a grand blueprint about China's space flight on the world stage, which is the embodiment of the great rejuvenation of the nation and has attracted the pride of hundreds of millions of compatriots who love the motherland!
Space dream is naturally a Chinese dream. If the spaceship is a ferry, then the astronaut is at the helm. This shows how important it is to train excellent astronauts.
Liu Wang is one of the docking personnel of Tiangong-1. There seems to be endless stories about him. He was born in an ordinary peasant family. Although the living standard is not high, the results are still excellent. When he was a freshman, he watched the report of the report group on the advanced deeds of Laoshan heroes, from which he deeply realized the sacredness of the motherland and strengthened his patriotic belief.
Because of this, his heart gradually accumulated the yearning to become an excellent astronaut, but it was not easy. In the following years, the pilot approached this dream step by step. Finally, I won a weightless test, won several places, and passed a strict examination in future training. Since then, Liu Wang's space dream has officially opened. After many failures and tempering, I disdainfully defended my beliefs. He has won many honors in his own space field, and he is worthy of the title of "model of the times". Isn't the fundamental reason for his success his enthusiasm and love for the motherland? Countless astronauts' patriotic beliefs have made generations of astronauts' space dreams and Chinese dreams come true. The driving force of the Chinese dream is powerful, and it will make people's will indestructible.
This patriotic belief will enable China to build the International Space Station in the future. You can even walk on any planet. Looking forward to this day.
In this era, every China compatriot has his own patriotic feelings. Like astronauts, we should shoulder the heavy responsibility of the times, shoulder our ideals, forge ahead, strive to be the masters of the future, and add luster to the Chinese dream.
Thoughts on 2022 primary and secondary school lectures by aerospace experts II
Generation after generation of astronauts have worked hard in the "experimental field" of aerospace, their hearts are full of latitude and longitude, and their feet are embedded in the vast sky. They struggled hard on the basis of poverty, strove forward in repeated experiments and pursuits, pursued Excellence under the challenge of Excellence, dared to break through difficulties and bravely opened up new roads. Astronauts learn experience and excellent skills in strict, systematic and comprehensive training. Flying in the sky and getting out of the cabin requires a solid foundation, excellent psychological quality and strong physique. Hard training in summer and winter gives them super willpower and self-confidence. For the great space cause, astronauts and astronauts regard hardships and twists as a "ladder" for their career development, forge their backbones with ambition, accumulate strength with backbone, and achieve a higher-level "innovation breakthrough" in the space cause through continuous struggle.
From the successful launch of Shenzhou I to the space trips of Shenzhou 5, Shenzhou VI and Shenzhou VII ... China's manned spaceflight project has achieved fruitful results. On the road of "chasing dreams", every time is a brand-new journey, and every time is an unprecedented challenge. Of course, unprecedented challenges and difficulties have also created unprecedented heights. Mr. Lu Xun once said: "In fact, there is no road on the ground. If there are more people walking, it will become a road." The road comes from two feet and is developed step by step. Since the development of China's space industry from 65438 to 0956, self-reliance and independent innovation have been consistent in the development, which is the core competitiveness to promote the development of space industry. It is bound to take detours to take the road that predecessors have not taken, and it is bound to encounter setbacks to break through the hurdles that predecessors have not taken. Only by being a pioneer can you become a pioneer. Only by daring to break through can we break a new world and seize the "new highland".
Great cause breeds great spirit. Looking back on the development history of the aerospace industry, whether it is the successful launch of "Dongfanghong-1" or the great achievement of Shenzhou manned spaceflight project; Whether the Beidou satellite navigation system is completed in an all-round way, or the "Chang 'e" flying to the moon and "Tian Wen" exploring fire, from bold ideas to successful practice, China's space strength that keeps pace with the times has been demonstrated. China's space industry has gone from a difficult start to a arduous journey and then to brilliant achievements, leaving behind China and China in the vast space, China spirit and China strength in the development of space industry. This spirit and strength will surely lead the 65.438+0.4 billion China people to work hard with one heart and one mind, forge ahead on a new journey and dream of a new era.

On July 23rd, 2020, China's first Mars exploration project "Tianwen No.1" was successfully launched in Wenchang, Hainan. On May, 200212002 15, Zhu Rong, the Tian Wen No.1 rover, successfully landed in the utopia plain of Mars. So far, the Zhu Rong Rover has traveled more than one kilometer, and * * * has obtained the original data of about 10GB.
From Qu Yuan's Tian Wen, "Who handed it down at the beginning of ancient times?" The Chinese nation has an infinite yearning for the universe. Now we are answering the ancient people's questions about space with practical actions. The successful landing of Zhu Rong, the rover, has filled the gap that there is no rover in China, which is of great significance to China's space industry.
Zhu Rong is regarded as the earliest Vulcan in the traditional culture of China. Named after Zhu Rong, it also means "May the future be bright and integrate ancient and modern China and foreign countries". China launched a probe car to Mars for the first time, and it was a direct success only once. Chinese astronauts once again showed China to the world. The rover separates from the orbiter and then enters the atmosphere. The trim wings are deployed, the parachute lander is deployed and landed slowly. This series of smooth processes is the most vivid footnote of China astronauts' unity, cooperation and hard work. From China's first satellite "Dongfanghong-1" to China's first manned spacecraft "Shenzhou 5", and now to China's?Tiangong?space station and the rover Zhu Rong, all these are the continuous extension of China astronauts' spirit of winning glory for their country and serving the motherland.
Even with the present glory, don't forget our backwardness. Prior to this, the United States and the Soviet Union were not optimistic about China and were unwilling to provide any help to our country. Any of these parts were independently developed and manufactured by Air China Rentian, and the hardships at that time were unimaginable, so now our technology can't fall behind!
The beauty of the motherland, the beauty of the motherland, not only because of the magnificent mountains and rivers, but also because of the friendship of the people and the spirit of the people of China. The people of China will strive for self-improvement and have a bright future. They will be able to integrate ancient and modern Chinese and foreign countries and make the world sit up and take notice! Young people are strong, the country is strong, and the responsibility on our shoulders is even greater. We should strive to learn scientific and cultural knowledge well, make contributions to the development of the motherland and create a better future.

Shenzhou XIII manned spacecraft will be launched in the early morning of June 10. In response, Zhao, a spokesman for the Ministry of Foreign Affairs of China, said on June 5438+05 that less than a month ago, China ushered in the triumph of the Shenzhou 12 manned spacecraft, and in the early morning of June 5438+06, China will once again watch the Shenzhou 13 fly into space with excitement. "This not only vividly interprets China's manned spaceflight spirit, which is particularly hard-working, especially capable of fighting, especially tackling key problems, and especially dedicated, but also reflects the scientific exploration spirit 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 said that on June 5438+05, the press conference of Shenzhou XIII manned mission was held in Jiuquan Satellite Launch Center, and a spokesman for China's manned spaceflight project introduced the relevant situation. Shenzhou 13 manned mission is the key technology verification stage of China's space station, and Chang 'e-6 mission is the decisive battle and final battle at this stage, and it is also the on-orbit construction process 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, the common cause of mankind. 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 building a community of human destiny. " He said.
Zhao said, it can be noticed that compared with Shenzhou 12, there are many differences in the group work arrangement of Shenzhou 13 mission, including that China female astronauts will be stationed in 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.
Thoughts on the 2022 lecture of space experts in primary and secondary schools 5
Who traveled abroad to study for the rejuvenation of the Chinese nation? Who gave up the superior conditions abroad for the prosperity of the motherland and resolutely returned to China from scratch? Who laid the foundation of China's nuclear bomb career and won the national medal of "two bombs and one satellite", and who dedicated his life to the motherland? It's him, Qian Xuesen, the "father of China's space flight" who has made great contributions to the country, is rigorous in his studies and is totally loyal.
Qian Xuesen lived in turbulent times in China. He knows that "backwardness is bound to be beaten, and science and technology can strengthen the country" and is determined to study hard for the rise of China. He studied in the United States with excellent results through clever talent and hard work. However, he never forgot his initial intention of serving the motherland and devoted all his strength to the study of atomic bombs. He studied, studied and worked day and night, and his work papers piled up like mountains, gradually piling up into a hill and becoming a core member of American scientific research institutions. When he received a phone call from his mother in New China, his eyes shone with the light of serving the motherland. He tidied up the manuscript neatly, packed his luggage and prepared to return to China. Knowing that Qian Xuesen had extraordinary talent, Americans tried their best to stop him. The ambassador came to Qian Xuesen's house and said, "Sir, if you stay in the United States, we will pay you." Qian Xuesen waved and his eyes were firm: "China needs me. As a China person, I must go back! " The ambassador was shocked by his absolute loyalty and had to let him go respectfully.
After returning to the embrace of the motherland, Qian Xuesen began to calculate around the clock. He knows that "thousands of miles away, it's a shame" must be foolproof. He combined the advanced technology of the United States with his bold ideas to innovate. His pen keeps writing on paper, as if China people were bullied by foreigners. Thinking of the poverty and backwardness in China a few years ago, he shouted in his heart: "Lead China forward with science and technology!"
1960165438+1On October 5, China's first missile flew into the sky; 1964 65438+1October 16, China's first atomic bomb opened a gorgeous flower in the air; 1970 On April 24th, China's first satellite traveled in space. This is a symbol of the rise of China, a glory that attracts worldwide attention, and the crystallization of the painstaking efforts of patriotic people such as Qian Xuesen!
There is no time to be quiet, but someone is carrying a heavy load for you. What I admire most is Qian Xuesen, the "father of China's space flight", who has made great contributions to the country, is rigorous in his studies and is totally loyal!
Thoughts on the lecture of aerospace experts in primary and secondary schools in 2022
Everyone in a great country and the whole world has dreams. Dreams are your courage to climb the peak. However, space dreams are naturally Chinese dreams.
Grandpa Zhang Houying, who is 80 years old, is very famous. Today, he personally came to the scene to give us a sixth-grade space knowledge science. Grandpa Zhang Houying, a kind-hearted, amiable, amiable but not dignified, not elegant, making people unattainable.
Grandpa Zhang told us in his report that today, Ark 1 will fly into space to refuel Tiangong 2. This is really the pride of the motherland. Grandpa Zhang also said that in 20 years, China's air ship will go to heaven.
Grandpa Zhang also raised a long list of questions, all of which were solved one by one. I also know the basic necessities of astronauts. Why should I answer them three times? Because it's training, I also learned eight necessary conditions for astronauts. I have two unsuitable conditions, which are my weight. I weigh 35 kilograms, but an astronaut needs at least 55 kilograms. Another thing is that there can be no scars. Because of the scar, it may lead to scar cracking during space flight. I also know that astronauts practice on weekdays, and when flying, blood will flood into their brains.
Grandpa Zhang also told us that some seeds on the ground will become huge and mutate in space, but not all of them are like this, and some will be the opposite.
Grandpa Zhang, today's speech, although I can't be an astronaut, I am proud that I am from China. I understand that after the flowers of our motherland bloom, we will soon be the pillars of the motherland, and the motherland will be built by us. Aerospace needs you, me and him.
Chinese dream, space dream.

"I'm a bird, and I can't fly high if I want to …" I hummed Zhao Chuan's "I'm a bird", walking on the road, feeling a little lost. I'm like that song. That bird, I'm human, how can people fly? Thought of here, I am very depressed. However, I still dream sometimes: my dream is to take a spaceship rocket, fly into space, travel, find a new life planet or other tasks, hehe, that would be great! But it seems unrealistic. Shenzhou 5 just picked up Yang Liwei alone. Can it be my turn? Alas!
I went into the house and turned on the TV as usual. I saw that the announcer of CCTV news broadcast was reporting: "At 9: 00 this morning, China's Shenzhou VI manned spacecraft was successfully launched at Jiuquan Launch Center, at the expense of astronauts and Nie Haisheng." I read the news reports about Shenzhou VI carefully almost every day to understand the basic situation of Shenzhou VI, the astronauts' food, clothing, housing and transportation, the difference between Shenzhou VI and Shenzhou V and so on. I am very excited and I feel incredible at the same time. My God, in just two years, China successfully launched two spaceships! You see, Shenzhou VI is much more advanced than Shenzhou V, and there are twice as many astronauts alone. At the same time, the flight time of Shenzhou VI also reached 1 15 hours and 32 minutes, which was several times more than that of Shenzhou V's 2 1 hour. What a big gap! In addition, there is food. Originally, God V was simple, but there are more than 50 kinds of God VI. In space, even fish-flavored shredded pork and kung pao chicken can be eaten! This can activate my brain cells: Yes! According to the current development speed, a spaceship will be launched every two years, and an astronaut will be added at a time. By 20 years, the spacecraft should be able to carry nine astronauts at a time, right? I can't help itching and rubbing my hands. I thought to myself, I want to make a plan, try to be an astronaut and travel in space!
The necessary conditions for becoming an astronaut are: superb flying skills, solid theoretical knowledge, strong physique, good psychological quality and reaction ability. Superb flying skills, good psychological quality and reaction ability can be cultivated slowly in the future. Now I will exercise regularly to improve my physique, and at the same time I will study hard and accumulate knowledge, hoping to become an astronaut when I grow up.
I believe that in the near future, my flying dream will come true, and I will definitely realize this dream!
