Manned space flight is the most complex, difficult and demanding system engineering in human space activities. According to the space station construction mission plan, the 1 1 mission will be carried out this year and next, including three space station module launches, four cargo spacecraft launches and four manned spacecraft launches. In 2022, the on-orbit construction of the space station will be completed and the National Space Laboratory will be built. After that, the space station will enter the application development stage.
Every task is a "big project", with the hard work and wisdom of thousands of people behind it. In order to ensure the smooth implementation of the task, all units of each system are fully prepared for the war.
Deep in the Badain Jaran desert, the vertical assembly test workshop of Jiuquan Satellite Launch Center is brightly lit and crowded, and the staff walks between the spacecraft arrow and the test instrument, running around day and night.
The aerospace industry has been described as "a thousand people with one arrow", and any link is related to success or failure, and no one can treat it lightly. As the home port for China astronauts to enter and leave space, Jiuquan Satellite Launch Center has built a safe "ladder" with meticulous attitude.
"The hoisting team of dozens of people cooperates with the task, and every step of operation can't go wrong, and the hoisting and docking error is even smaller. Each product can only be hoisted and landed successfully once, and there is no chance of turning over and no mistakes. When hoisting the docking rocket, dozens of bolts in a circle should be aligned and connected at one time. " Shi Chuangfeng, the base staff, undertakes the lifting work. In order to be fast and steady, he invented his own training method, tied a covered electrode to the hook and operated a crane to insert beer bottles from high altitude. At the end of the exercise, he and his colleagues waved the heavy crane iron arm as flexibly as they waved their own arms.
Thousands of flights, safety first. Taking the life safety of astronauts as the bottom line, the Shenzhou-12 manned spacecraft team of China Academy of Space Technology has made plans and measures to ensure the safety of astronauts at all stages of launch, flight, docking, docking and return of Shenzhou-12, and will also start the emergency rescue mission mode of manned spacecraft for the first time to fully ensure the astronauts' safe travel between heaven and earth.
Only by truly understanding where the starting point and road of manned spaceflight project are, can we draw strength from history and make better progress. The Shenzhou 12 manned spacecraft will be launched by the Long March II F- 12 carrier rocket. During the preparation of the mission, the temporary Party Committee of the Long March II F- 12 launch vehicle team of China Academy of Launch Vehicle Technology led everyone to the Dongfeng Revolutionary Martyrs Cemetery to remember the heroic deeds of Marshal Nie and many revolutionary martyrs, and called on everyone to complete the mission with a strong sense of responsibility, superb technology and brave spirit, and firmly hold the baton.

"Flying dreams never lose weight, and scientific dreams have unlimited tension." _ Years ago, "space teacher" Wang Yaping gave a lecture to more than 60 million students in China. Now she is once again on a trip to space, and will become 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 and "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.

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. China "The first world-class high-speed railway between Beijing and Tianjin was opened", and the first research achievement of human genome sequence in China was published. "The major reconstruction project of the Beijing Electron-Positron Collider has been successfully completed", and Shuguang 5000A ranks among the top ten supercomputers in the world.
China's scientific and technological strength continued to improve. 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 has come true today. On July 23 last year, Tian Wen-1 was launched by the Long March 5 carrier rocket from Wenchang Space Launch Site and successfully entered the scheduled orbit. Tian Wen-1 arrived on Mars in February, 20021,and captured it. In May of 20021year, the orbit 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 and other work, so as to scientifically detect the surface morphology, soil characteristics, material composition, water ice, atmosphere, ionosphere and magnetic field of Mars, realize the technological leap in the field of deep space exploration in China, and promote the all-round development of space science, space technology and space application.
As of February 3, 20021year, the total flight distance 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 Wanshuizi Mountain. We will continue to struggle, forge ahead and create greater glories!
The space products of Shenzhou XIII will stay in orbit for 6 months as planned. In this half year, the main work is to further verify the key technologies of 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.

The aerospace industry has always been a vivid epitome of a country's pursuit of innovation and development. Since the 1990s, China's manned spaceflight project has now reached the third step, namely, "building a space station to solve the problem of large-scale and long-term manned space applications". The Long March V-B carrier rocket will undertake the important task of launching the space station cabin in the future, and its first flight is of great significance, which is related to whether the "three-step" strategic goal of manned spaceflight project can be realized. Faced with the adverse effects of the COVID-19 epidemic, the astronauts overcame many difficulties, won this tough battle, and strengthened their confidence in completing the follow-up mission. The launch of the Long March V-B carrier rocket is the achievement of China in building a space power and a world science and technology power. It also once again showed people the powerful spiritual strength of not being afraid of risks and challenges and being brave in breaking through and climbing.
Pushing open the door of the space station era, China Aerospace has demonstrated its confidence in unswervingly following the road of independent innovation with China characteristics. The launch time of the Long March V B carrier rocket was announced in advance, and finally the rocket was launched in a "zero window" within one second. From Shenzhou-9, Shenzhou-10 to Long March-5 B carrier rocket ... The launch times of several missions were announced in advance, accurate to the minute, which fully demonstrated the confidence of astronauts. Self-confidence comes from 16 manned space flight since the launch of Shenzhou-1 spacecraft, and also from the consciousness of always implementing and adhering to quality first and safety first in the manned space flight project with the most complex system and the highest safety requirements. Self-confidence is not only honed by "grinding a sword for ten years", but also depends on climbing and challenging the unknown. After the successful launch, the words: Dare to overcome all difficulties and obstacles and dare to climb the peak of space science and technology are printed on the screen of the lobby of Wenchang Space Launch Site. Struggle is a reward for the strugglers. China's space sword is boundless, and the "Long March" is always on the road.
Exploring the vast universe, developing the space industry and building a space power are our unremitting pursuit of the space dream. From _ _ years ago, the first man-made earth satellite "Dongfanghong-1" started the space age. Today, the curtain of the space station era is slowly unfolding, and China Aerospace has once again embarked on a new journey. The space station is an extremely complicated and challenging step, but the huge gains will be unparalleled, which can accelerate the pace of exploration, development and utilization of the universe in China and even mankind. The leap of space station and space technology can also promote space achievements to benefit social development and people's lives more widely and deeply. As a pioneering work in near-earth space, the construction of the space station will lay the foundation stone for further realizing the longer-term goals such as manned lunar exploration and Mars exploration, and become a symbolic innovative practice of serving the country by space and strengthening the country by science and technology.
When replying to the old scientist who participated in the "Dongfanghong-1" mission, he emphasized that "no matter how the conditions change, the ambition of self-reliance and hard work cannot be lost". Following the example of the older generation of astronauts, astronauts in the new era will vigorously carry forward the spirit of "two bombs and one satellite", dare to overcome all difficulties and obstacles, dare to climb the peak of space science and technology, and will surely cross the sea of stars and achieve more extraordinary achievements.

1654381At 20: 43 on October 3, China's new generation launch vehicle Long March 5 was ignited and lifted off at Wenchang Space Launch Site. The load assembly was successfully separated from the rocket and entered the predetermined orbit, and the first launch mission of Long March 5 was a complete success.
At 07: 30 and 365: 438+0 on June 65438+1October 07, Shenzhou XI spacecraft was successfully launched by Long March II FY1rocket at Jiuquan launch site. After it is in orbit, it will complete the rendezvous and docking with Tiangong-2 to form an assembly, and the astronauts will work in the assembly for 30 days. The construction of China's space station has taken another big step forward!
Today, China heavy rocket Long March 5 is ready to go! Prior to this, China has successfully launched a new generation of rockets such as Long March 6, 11 and 7, forming a complete system.
Whenever this kind of news appears, someone will always ask, is space so far away from us that it is worth spending so much money and taking such a big risk to explore? What changes can space technology bring to the lives of ordinary people?
Ouyang Ziyuan, an academician of China Academy of Sciences, the chief scientist of China's lunar exploration project and the "father of Chang 'e", specially wrote an article to explain this issue in simple terms. Let's have a look!
Space technology is a highly integrated system of modern science and technology. For example, the Apollo program is one of the largest and most expensive scientific and technological projects in human history. More than 20,000 enterprises, more than 200 universities and more than 80 scientific research institutes participated in the Apollo program, with a total number of more than 400,000.
The implementation of the Apollo program promoted the development of a large number of high-tech fields such as giant rocket, microwave radar, radio guidance, synthetic materials, computer, electronic technology, automatic control, vacuum technology, cryogenic technology, semiconductor technology and manufacturing technology in the 1960s and 1970s. The Apollo program produced more than 3,000 new technologies, promoted scientific and technological progress and industrial prosperity, and achieved great economic and social benefits.
Space activities promoted the birth, growth, popularization and application of a series of high-tech, and gave birth to the formation, innovation, exploration and development of a large number of new disciplines.
Space activities have had a great impact on many aspects of national economy and social life and changed the face of the world. The development of aviation has not only changed the structure of transportation, but also been widely used in aerial photography, geodesy, geological exploration, resource investigation, sowing and fertilization, weeding and pest control, forest fire prevention and environmental protection, which has had a far-reaching impact on the transformation of traditional production methods.
Space technology directly serves many fields of national economy. Satellite communication, satellite radio and television, satellite weather forecast, satellite navigation, satellite resource exploration, disaster forecast and environmental monitoring have changed people's production and life style, resulting in huge economic and social benefits. The application of various scientific exploration satellites, astronomical observation satellites and scientific experimental satellites has broadened human horizons, made a lot of new discoveries, updated human understanding of earth space, solar system and the whole universe, and produced a series of emerging disciplines.

"Space teaching" has opened up a new way of face-to-face teaching of science and technology with students. This is a brand-new educational reform, which will inevitably inspire students to face more teaching methods in the social field. For example, writers and students teach face to face, for example, entrepreneurs and students teach face to face, and so on. Running education well is not only the responsibility of the school, but also the responsibility of all fields of society. We all know this responsibility, but it is not enough. Today, space teaching has taken a big step. I firmly believe that this great step will surely lead to more fields of social teaching, which will surely become a brand-new content of education reform in China, and the sacred duty of social education will surely be well implemented.
"Space Teaching" was successfully taught by a speaker and two people. This is a pioneering work, breaking the tradition of teaching by one person in the classroom. The author believes that this teaching method should be promoted through local interviews. On the one hand, there are many students in our class and the teacher is very tired. On the one hand, multi-person teaching is more vivid, three-dimensional and diverse, which will inevitably create a more substantial learning atmosphere for students. This is a pioneering work of educational reform.
"Space teaching" is unique in teaching with immersive feelings. Teachers are integrated with knowledge and environment. Teachers are immersed in teaching, students are immersed in learning, and the image synthesis of teachers, classrooms and knowledge is truly achieved. As a classroom for ground teaching, we should learn from it and create a classroom according to the on-site environment, current teaching content and teachers' personality. Only a good classroom is the most beautiful classroom.
"Space teaching" is the crystallization of high technology and the achievement of educational modernization, which will certainly inspire our educational Chinese dream to be more brilliant.
I hope there will be more such space lectures in our Chinese dream education, such as lectures in factories, shopping malls, warships and airplanes. The Chinese dream is a concrete dream of three-dimensional, socialized, modernized, visualized, diversified and networked education.

Struggle is the wing of a round dream. 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 aerospace industry, 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 higher-level innovation and breakthrough in the aerospace industry 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.

This time, Shenzhou XIII has many "bright spots": compared with Shenzhou XII staying in space for three months, this time it is half a year, three astronauts will spend the Spring Festival in space, and we will receive the New Year greetings from space for the first time on earth; This is the first time that a female astronaut from China has entered the China Space Station, and astronaut Wang Yaping will also become the first female astronaut in China to carry out extravehicular activities. This time, the space station will conduct radial docking by autonomous rapid rendezvous and docking for the first time; This manned mission will carry out 2 ~ 3 extravehicular activities and so on.
From Shenzhou-1 to Shenzhou-13, from 2003, when Yang Liwei was the first astronaut in China, he realized his Millennium dream of traveling in space. Up to now, there have been 12 people in China, and China's space industry is making great strides. The grand project of space station construction will be completed step by step in an orderly manner, and we firmly believe that it will go smoothly in the future; With the unremitting efforts of generations of China astronauts, the space dream related to human peace and progress will definitely come true, and we are full of confidence in it.
For China people, behind this excitement, there is more calmness. Behind decades of space career is the great road to national rejuvenation. We have experienced the struggle of the country and felt the rapid progress of this country in the changes of daily life.
In the future, we will also witness the launch of Shenzhou XIV and Shenzhou XV. Every witness has strengthened people's confidence in the country and the future. It is an indisputable fact that the strength of science and technology is getting stronger and stronger. It is a change that people can see and touch, not just an illusion. Therefore, this is not only a story of China astronauts passing on their dreams from generation to generation, but also a story of people becoming more confident, the country becoming stronger and the nation becoming more hopeful.
We can't help looking back on the past. The more we look back on history, the more we can understand the present. The more you look back, the more you cherish it. We will constantly review every important node of China's scientific and technological undertakings, and look for the motive force of national progress in these landmark events. Those moments, because memories become eternal.

Tiangong is a space station independently developed by China. Needless to say, the name "Tiangong" was not casually named. It's like a palace with everything.
The space station is a "space hotel laboratory", where astronauts can stay for a short time and conduct various space research and experiments. Then why build a space station? The space station can test all kinds of technical equipment that may be used for space flight in the future. You can also get a "weightless" environment-a special environment that is difficult to stay on the ground for a long time. However, the cost of going to and from space is quite high. Being able to stay in space for a longer time at a time can reduce costs and improve work efficiency. So such a place with comprehensive functions that astronauts can live for a long time was born.
First of all, introduce the planning of our "palace".
Tianhe core cabin is the bedroom in the palace, mainly for astronauts to live in. Goods and manned spacecraft are used to transport goods and people, just like vehicles on the ground. The candlestick experimental module and the dream experimental module have not been completed yet. They are R&D laboratories in the "Palace" for various space experiments and scientific research.
There are all kinds of imaginable dangers in space, among which the threat comes from the sun as we know it. As we all know, the sun is the foundation of life on earth. It provides endless energy and nourishes the growth of all things. But the rays and gamma rays it releases are very deadly. These two rays can easily penetrate your skin and destroy all cells in your body. Then why can we bask in the sun every day on the earth? That's because the earth's magnetic field and atmosphere will reflect or absorb them. This safety factor must be considered in the site selection of the space station. Internationally, the distance from the ground 1000 km is generally chosen. For the sake of safety, our "Tiangong" is located 400 kilometers above the ground. This can be protected by the earth's magnetic field and atmosphere, killing two birds with one stone.
In ancient times, it was said that the Temple of Heaven was in the clouds, and all kinds of immortals lived there. At present, many astronauts and scientists live in the "Tiangong". They are working hard for the progress of China's space science and technology in high altitude, so that we can no longer rely on foreign technology, and we can really look at the whole universe while overlooking the earth and have a deeper understanding of space.
So our "heavenly palace" is really a veritable heavenly palace! Perhaps this is the origin and beautiful meaning of the name "Tiangong".
The door of "Tiangong" has been opened, and the future can be expected!
