Ten comments on the second space lecture of Shenzhou XIII in 2022

According to the China Manned Space Engineering Office, the second class of "Tiangong Classroom" will be held at the China Space Station on March 23rd 15: 40, and Shenzhou XIII astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu will cooperate with each other to teach. The following is my review of the second space lecture of Shenzhou XIII. Welcome to read!

Reflections on the Second Space Teaching of Shenzhou XIII 1 2008

"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, 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.

Reflections on the Second Space Teaching of Shenzhou XIII

The space teaching in the Tiangong classroom has officially started. It should be said that this is a feat of China's space industry. It not only indicates that China has been able to skillfully use manned space technology, but also means that China's space science and technology has once again extended an olive branch to the field of education.

This time, China astronauts passed on scientific knowledge in 300 kilometers of space, showed the charm of the universe to the world with various space experiments, and inspired countless students' interest in mysterious space. Teacher, preach and teach. However, teaching scientific knowledge in person by giving lectures in space can only be a feat that can be accomplished in modern human history. When Confucius was studying in Xinglin, how could he think that one day, his descendants would rush to space like Chang 'e and preach and dispel doubts in space? It is said that "teacher is the most glorious profession under the sun", but Morgan and Wang Yaping spread the glory of this profession into space, and let the whole universe be bathed in the glory of human nature. If the vast universe is a book, then the powerful comprehensive national strength and solid space technology are undoubtedly the wisdom keys to open this book.

China astronauts' teaching in space has opened a magical space journey for us, and their Voice of China is also infecting and touching everyone around us. However, the unknown vastness and far-reaching educational significance of space also put forward higher requirements for China's manned space flight. If we want to absorb more nutrition from the universe, we must vigorously develop manned space flight and education. And we also hope that this space exploration can take us to more distant places, so that more places can hear the "good voice of China." This space teaching has aroused students' inner love for learning, which can be transformed into simple feelings of loving the motherland, learning and science. Let us teach less in our daily work and encourage and train future successors more attentively.

Reflections on the Second Space Teaching of Shenzhou XIII

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, the space station 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.

Reflections on the Second Space Teaching of Shenzhou XIII

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, it is generally chosen at a distance of 1000 km from the ground. For the sake of safety, our "Tiangong" is set 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, there are many astronauts and scientists living 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!

Reflections on the Second Space Teaching of Shenzhou XIII

From 10, the astronauts of China manned spacecraft Shenzhou-10 gave us the first lesson in space in the Tiangong cabin, which is more than 300 kilometers away from the earth, and let us know some strange weightlessness phenomena in magical space!

I am very excited after watching Aunt Wang Yaping's space demonstration with rapt attention! What a magical phenomenon weightlessness in space is! What can't be done on earth can be easily achieved in space! For example, Uncle Nie Haisheng easily turned a somersault, like a martial arts expert! Also, wrap the ball around a line with a support frame, gently touch the ball, and it will make a circular motion; But on earth, when you do this, the ball will swing back and forth repeatedly. What a strange phenomenon!

The experiment of gyro surprised me even more! A stationary gyro will roll forward at the touch of a finger. This is impossible on earth, unless this gyro is enchanted by Balala!

Aunt Wang Yaping's demonstration of "drinking water" is also very interesting. She squeezed a drop of crystal clear water from the drinking bag, then took a sip and "drank" it. And that magical water film can actually hold a Chinese knot; Transparent water polo can be used as a lens; Water polo is injected with two small bubbles, which exist independently. When red liquid is injected, the transparent water polo becomes a beautiful red water polo! What a wonderful phenomenon!

I don't know much about physics in this space lecture, but I only saw some interesting phenomena. I must study hard, master more scientific knowledge and explore the mysteries of space in the future!

Reflections on the Second Space Teaching of Shenzhou XIII

Wang Yaping and other Shenzhou-10 astronauts showed us some small experiments about physical concepts, such as using a special mass measuring instrument for space and a speed measuring system that can measure the acceleration of motion, so as to measure the mass of objects in space; Or use the ball on the bracket to demonstrate how the ball will move in weightlessness; Teacher Yaping also showed us with a metal ring and a water bag that when the metal ring put in the water bag is pulled out under weightlessness, there is a water film on the ring, which is difficult to achieve on earth. Let us understand the motion characteristics of an object in weightlessness and the effect of liquid surface tension, and at the same time deepen our understanding of basic physical concepts such as mass, weight and Newton's law. The teacher also injected red liquid into the water polo, showing us that in space, the red will slowly disperse in the water polo and eventually form a big and red water polo. That water polo is beautiful, just like space, mysterious and charming.

In addition to experimental demonstrations, many students are interested in space-related issues, such as whether they have seen space junk. In this regard, Mr. Yaping said that space debris does exist, and there are still many, but the probability of collision with spacecraft is very small, otherwise the consequences will be unimaginable. Since the launch of 1 1, Shenzhou-10 has not seen space junk, but this is mainly due to the early warning and analysis of space junk by Tiangong-1, and the corresponding avoidance and protection, which makes the space trip so smooth these days.

Some students asked whether the domestic water in space was recycled. I am also very interested in this issue. Commander Nie Haisheng told us that the water used by the spacecraft was brought from the earth, but it does not have the function of recycling at present, because it requires more advanced technology and complex equipment. After watching the Shenzhou-10 space lecture, I know that I must study hard now, study science well and make contributions to the motherland in the future.

I believe that in the future, more people will be interested in the mysterious space and willing to play a greater role in our space industry and realize our Chinese dream!

Thoughts on the Second Space Teaching of Shenzhou XIII

A few days ago, we watched Wang Yaping's "Space Teaching" in Tiangong-1. She did many things in space that could not be done on earth, such as acrobatics, gyro, simple pendulum, water film, water polo and circular motion.

Let's start with acrobatics. Acrobatics takes a long time to practice on earth, which is very dangerous. But in space, it's easy. Just roll in the air. It's like a Hercules. You can lift a person with one finger.

As we all know, gyro is one of the toys when people were young. In space, if you let it float in the air and give it a disturbing force, the clumsy gyro will start to roll. But if you let it rotate first and then disturb it, at this time, it won't roll.

The name "simple pendulum" sounds strange, but it is unsuccessful in weightlessness, but if you give it a small force, it will do "circular motion"

I was dumbfounded when Mr. Wang Yaping filmed my favorite water film. This water film is very different from the mask in life. After water is pumped out, a large water film is formed on the metal coil. Why is this? There is only one reason: weightlessness! A short sentence is full of wisdom, science and space are really interesting!

These experiments should not be simple, but the physical knowledge behind them is amazing.

Someone asked, "Is the domestic water in space recycled?" For this question, commander Nie Haisheng told us: "The water in the spacecraft was brought from the earth, but it does not have the function of recycling at present."

I believe that in the near future, more people will be interested in the mysterious space and willing to play a greater role in the space industry. Close to realizing "Chinese dream, space dream"!

Reflections on the Second Space Teaching of Shenzhou VIII

With the development of science and technology in China, many things that people dared not think before have now come true.

During the Shenzhou-10 flight, some strange physical phenomena will be displayed through celestial interaction, and female astronaut Wang Yaping will become the first "space teacher" in China. The teaching content is mainly to let teenagers know the characteristics of object movement in microgravity environment, understand the role of liquid surface tension, and deepen their understanding of basic physical concepts such as mass, weight and Newton's law. Astronauts give on-orbit explanations and experimental demonstrations, and interact with the ground in two ways. We see magical surface tension, interesting water film and transparent water polo. Space, creating wonderful phenomena, is really refreshing. Wang Yaping told a joke: "If the poet Li Bai lived in the Heavenly Palace, he could not write the poem" Climbing over the eaves and climbing over the walls ".

The ball will move in a circle instead of swinging like a pendulum we see on the ground; The little gyro will go forward with somersaults, and turn directionally when it keeps turning, and naturally stop rolling. That's how the earth goes. A drop of water, the state of dew, space is like a big lotus leaf, which can catch dew. The experiment of weightlessness can be done on the earth, but seeing the changes in space makes the sense of surprise more intuitive. The most interesting experiment that impressed me most was to make a water film with a ring. Ordinary water film needs the characteristics of soapy water to form a transparent film, while in the weightless environment in space, only ordinary water is needed. Seeing that Mr. Wang Yaping separated and merged the rings in his hand to form a water polo, he kindly explained: "Through water polo, students can also see reflection imaging!" Say that finish, then blinked, let the students feel closer.

After reading this space lecture, it is an introduction and preview for me who is about to enter the second day of junior high school. It also aroused my interest in learning physics and enhanced my confidence in learning physics.

This time, Wang Yaping, as an outstanding representative of China astronauts, passed on scientific knowledge in 300 kilometers of space, showed the charm of the universe to the world with various space experiments, and inspired countless students' interest in mysterious space. Teacher, preach and teach. However, teaching scientific knowledge in person by giving lectures in space can only be a feat that can be accomplished in modern human history. When Confucius was studying in Xinglin, how could he think that one day, his descendants would rush to space like Chang 'e and preach and dispel doubts in space? It is said that "a teacher is the most glorious profession under the sun", but Wang Yaping spilled the glory of this profession into space, so that the whole universe was bathed in the brilliance of human nature.

If the vast universe is a book, then the comprehensive national strength is strong and solid. Space technology is undoubtedly the key to open this book. Wang Yaping's space teaching, Wang Yaping opened a magical space journey for us, and her "The Voice of China" is also infecting and touching everyone around us. However, the unknown vastness and far-reaching educational significance of space also put forward higher requirements for China's manned space flight. If we want to absorb more nutrition from the universe, we must vigorously develop manned space flight and education. And we also expect that the space adventure of Shenzhou-10 will take us to more distant places, so that more places can hear The Voice of China.

This space teaching has aroused students' inner love for learning, which can be transformed into simple feelings of loving the motherland, learning and science. Let us teach less in our daily work and encourage and train future successors more attentively.

Reflections on the Second Space Teaching of Shenzhou XIII

This is an exciting moment, and it is the first time that China has given a space lecture on the shenzhou spaceship. This is unprecedented in China and the second time in the world. I was in it, and once again, as a "student", I had an amazing space class.

"I'm Wang Yaping, and this lecture will be given by me." With this greeting from Tiangong, Wang Yaping, the first space teacher in China, jumped gently and floated to the camera lens in Tiangong-1 cabin. Curved arch eyebrows, clear eyes and sweet smile. I seem to be walking in space. I saw Chang 'e and the fairy with my own eyes, and she floated in. Like a dream.

The lesson with the most amazing content, the farthest classroom and the largest audience began.

"Immortal" Nie Haisheng meditated in the air, crossing his legs lightly like a Buddha in mid-air, "Chang 'e" Wang Yaping performed magical work, gently pushed his fingers, and the "Immortal" staggered far away, vividly demonstrating the wonderful characteristics of object movement in weightlessness environment in space.

"In space, we are all martial arts masters." Wang Yaping's words caused laughter and applause from the students in the ground class. "If the poet Li Bai lived in the Heavenly Palace, he probably couldn't write the famous sentence" Flying down three thousands of feet "because water can't fly down in a weightless environment." "Students, it's time to witness the miracle." After the punch line, Wang Yaping squeezed a drop of water from the drinking bag, suspended it in the air, and then she ate it. "It just moistened my throat."

After the curtain was lifted easily, Wang Yaping performed a unique trick, including a circular pendulum, a constant axis gyro, a crystal clear water film and a red water polo. China's first space lecture was perfectly displayed in fun and surprise.

With vivid and interesting language and skillful operation, she made China's first space lesson laugh and surprise gifts.

It is understood that on August 14, 2007, American Barbara Morgan gave the first human space lecture on the International Space Station. She showed the students the scene of exercising and drinking water in space through video.

Compared with Barbara Morgan's space teaching, China astronauts' space teaching is not only more scientific and technological, but also more difficult. "Morgan's lecture on space is to introduce and demonstrate life in space, while Wang Yaping's lecture is to introduce and demonstrate physical concepts, so the latter is more scientific and more difficult."

After Wang Yaping and Shenzhou-10 flew around the earth for nearly half a circle, the classmates in the classroom felt the cabin environment with her-the water droplets floating with their throats, the crystal ball made in their hands and the Chinese knot adsorbed on the film-this 40-minute journey more than 350 kilometers from the surface of the earth is destined to go down in history.

It created a number of firsts: the first time in the history of China's manned spaceflight project, China students and our audience watched a number of weightless experiments from space for the first time through live images.

Since ancient times, there have been legends of "a thousand miles a day" and "a day in the sky and a year on the ground" in China, so astronauts can get comments. They can see the sunrise at 16 every day, because they circle the earth once every 90 minutes.

Strong comprehensive national strength and solid space technology provide a solid guarantee for us to watch space teaching smoothly. This space lecture has opened a magical space journey for us, and Wang Yaping's beautiful teaching voice is also infecting and touching everyone around us. We also expect that the space exploration of Shenzhou-10 will take us to more distant places. I believe that the country that can let God X fly into space will eventually lead us to realize better dreams such as "Chinese dream and space dream"!

Thoughts on the Second Space Teaching of Shenzhou XIII 10

At 0: 23 10 on June 6th, Beijing time, the Long March II F- 13 carrier rocket carrying the Shenzhou XIII manned spacecraft was launched at Jiuquan Satellite Launch Center. The Shenzhou XIII 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. Three astronauts rushed to the sky with the expectations and blessings of all China people, and went to China Space House in the vast universe.

Although the launch time was in the early hours of the morning, the news of "complete success" came out, and the Internet was full of jubilation. Countless netizens were waiting for this moment and were full of feelings about the success of the launch.

According to the "convention" that China Aerospace never stops, Shenzhou 13 will also achieve several "firsts": radial rendezvous and docking with the core module; The first stay in orbit is 6 months, which is also the normal stay period of astronauts during the operation of the space station; For the first time, it was transferred from a rescue ship to a formal mission ship.

In addition, compared with Shenzhou 12, Shenzhou 13 has many special features. For example, after the docking of China Space Station, the space station will realize the combined operation of core module, two cargo spacecraft and 1 manned spacecraft. Spacecraft and rockets carrying out missions are also directly transferred from the backup state of emergency standby to the launch state at the launch site.

Moreover, after the Shenzhou-13 mission, all the functions of the space station mission standard manned spacecraft will be verified in orbit, which fully meets the needs of supporting the subsequent construction and operation of China's space station, and also marks the official transfer of the project from the key technology verification stage to the on-orbit construction stage, which is of great significance.

As netizens said, "You can always trust China Aerospace", China Aerospace is always surpassing, achieving technological breakthroughs bit by bit and refreshing the scale of outer space at an increasingly fast frequency. After several generations of efforts and dedication, we can proudly say today that China has become an important "player" in world space exploration, and there will be more and more human footprints from China in space.

Despite the technical shock, today's China Aerospace has become more and more calm, confident, warm and romantic, and has a unique Chinese charm.

For example, the flight crew of Shenzhou XIII included Wang Yaping, the first female astronaut of China Space Station. Before leaving, she specially sent a circle of friends who had been on a business trip for half a year, and her humorous expression revealed a sense of confidence. At the scene of the war, Wang Yaping's daughter came to see her mother off and shouted "Come on, mom". This scene touched countless people, and "Mom started to pick stars for you" quickly became a hot topic on the Internet.

The Shenzhou XIII mission will last for half a year and will span the China Lunar New Year. The astronauts' first Spring Festival in space has also attracted much attention. Previously, when the Tianzhou-3 cargo spacecraft sent a "space express" to the space station, it had already prepared Spring Festival supplies for astronauts. At that time, astronauts will also celebrate the Lunar New Year in space with all China people. These meticulous and ingenious arrangements make the "scientific narrative" of aerospace hardcore reveal deep humanistic feelings.

Now, Shenzhou XIII has officially started its space journey. We wish the astronauts a successful mission, and we also believe that China Aerospace will bring us endless surprises and go further with our dream of becoming a great country.
