Shenzhou 13 Lesson 2

The second class and the first class of Shenzhou 13 lasted about 60 minutes. The astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu of Shenzhou-13 flight crew brought a wonderful space science lesson to the majority of young people. When is the second lesson of Shenzhou 13?

The second lesson of Shenzhou 13 1 has not been officially announced.

On February 9, 65438, the first lesson of "Tiangong Classroom" was officially opened at the China Space Station, 400 kilometers above the ground. This is the first time that China astronauts have taught in space after eight years, and it is also the first time that China Space Station has taught in space.

During the 60-minute lecture, the astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu of the Shenzhou 13 flight crew brought a wonderful space science lesson to the young people.

The connection between heaven and earth

Feel the life of astronauts in the space station

Lens one

On the big screen of the main classroom on the ground of China Science and Technology Museum, the real-time picture has changed from the space station flying around the blue earth to the spacious and tidy core cabin of the space station. A yellow gyro appeared in the camera, and Wang Yaping's voice sounded:

"Space exploration is endless. With the spinning gyro, we entered the space station era from the Shenzhou-10 mission. Welcome to the' Tiangong Classroom'! " Wang Yaping greeted his classmates and humorously introduced the "feel good group" around him.

"Hello, classmates, I'm Zhai Zhigang, the commander." "Hello, classmates, I am astronaut Ye Guangfu."

In the bright core cabin of the space station, Wang Yaping took his classmates to visit the "Space House". There are three sleeping areas in the pillar part of the core cabin. Wang Yaping's sleeping area is very warm, with photos of his family and his favorite gadgets. Through the porthole, you can see the beauty of space and the earth.

"In a weightless environment, the blood distribution is different from that on the ground, and the blood in the lower part is upwelling, so our faces will look very fat. This will affect health, so we have to fight against the physiological effects of weightlessness through various exercise methods. " Wang Yaping demonstrated how to use a space treadmill and a space bike.

In the space kitchen, there are heating devices, drinking water distributors and food freezers in the space cabinets. Wang Yaping gently opened the food cooler and took out a fresh apple. The drinking water distributor is the place where domestic water is taken. Wang Yaping said that with the development of technology, the domestic water in the space station cabin has been regenerated, and every drop of water will make the best use of it.

In order to show how to fight weightlessness in space, Ye Guang Fu became Zhai Zhigang's model. Zhai Zhigang introduced that in order to prevent muscle atrophy caused by weightlessness, in addition to sports tools, there is also a "secret weapon", which is the "penguin suit" worn by Ye Guangfu. It has many straps to keep muscles tense and fight against muscle atrophy. "Behind the small clothes, the ingenuity of aerospace science and technology experts is concentrated." Zhai Zhigang said.

With Wang Yaping's "guided tour", the space station seemed to be in sight, and applause sounded from time to time in the class on the ground.

Heaven and earth experiment

"Can you walk normally in space?" To answer this question, Wang Yaping asked Ye Guangfu to try to walk like on the ground. Ye Guangfu "stepped on" a few times and floated involuntarily, causing everyone to laugh. "Without gravity in space, you can't walk normally like on the ground." Wang Yaping revealed the answer.

"Not just walking, hovering in space and on the ground are also very different. It is difficult for us to turn around in space. " Wang Yaping asked Ye Guangfu to demonstrate the difficulty of turning around in space, neither swimming nor blowing. Finally, he raised one arm and kept turning around, and finally turned around successfully.

In the interaction between heaven and earth, I also did a small experiment.

In the ground class, the students put the table tennis in the water cup and the ball floated. In the space station, Wang Yaping put the ping-pong ball in the water cup, but the ball stayed in the water. "This is because buoyancy almost disappears under weightlessness."

Later, Wang Yaping took out the origami flowers that she and her daughter had prepared on the earth together and put them in a thick water film. Flowers "bloom" while spinning. "We got a flower blooming in space, which is very beautiful. When I saw this flower, I thought of my daughter. " Wang Yaping said emotionally.

Wang Yaping encouraged the students: "You are all flowers of the motherland, in bud, and the future is yours. I hope your dream can bloom in this vast universe. "

Next is the "Space Fun Ball". Wang Yaping kept adding water to the water film, and made a water polo that could not be made on the ground by using the surface tension of water in weightlessness. Then she injected the blue pigment and put half an ordinary vitamin effervescent tablet. In an instant, the water polo turned blue. Bubbles keep coming, but they don't leave the water polo.

"Why didn't the bubbles leave the water polo?" Wang Yaping said that this is because in weightlessness, buoyancy disappears, and bubbles no longer float, but squeeze each other.

Wang Yaping said, "Does this little blue ball look like our earth? The earth is the cradle of human beings in the universe, but human beings cannot live in the cradle forever. Now that we have our own space station, China people will step into the moon, Mars and further deep space in the future. "

"Can we send you an email?" The students in Macau Diya class ask questions.

"At present, we can send emails and videos to the ground in the core cabin. Usually we can watch movies, novels, music and TV. The channels are very rich. You can also have two-way communication with your family on weekends. However, at present, our email communication with the ground needs special treatment, and we can't receive emails from our classmates for the time being. However, if you have any ideas, you can leave us a message online, and welcome everyone to comment positively! " Ye Guangfu answered.

The space experiment has not been completed yet, and there is a wonderful interaction between heaven and earth.

"How do oxygen and carbon dioxide circulate in the space station?" The students in Guangxi ground class asked.

Ye Guangfu replied that the space station uses the electrolytic oxygen generation subsystem to generate oxygen, and the carbon dioxide removal system removes carbon dioxide. There will also be a carbon dioxide reduction subsystem in the back, which can react hydrogen produced by electrolytic oxygen production with carbon dioxide produced by human body to generate water. "This will greatly improve the material circulation capacity of our space station."

Unconsciously, the "space teachers" will say goodbye to the students in the ground class. Every astronaut sends space information to his classmates-

"Students, space technology is full of mysteries, and the future belongs to you!" Zhai Zhigang said.

"The starry sky is boundless and there is no end to exploration. I hope that the students will sail their dreams and sail to the boundless universe. " This is Ye Guangfu's wish.

"Flying dreams will never lose weight, and the tension of scientific dreams is infinite! Students, I look forward to seeing you next time. " Wang Yaping said.

The magical "Tiangong Classroom" ignited children's scientific dreams.

Xu, a sixth-grade student at Chaoyang Branch of the High School Attached to Beijing Municipal People's Congress, said: "The Tiangong class taught me the structure of the space station. I also visited the space station with the astronauts to understand what the astronauts were doing there. It turns out that space knowledge is so interesting! "

Teacher Tan, director of the Science and Technology Office of the middle school affiliated to Tsinghua University, said: "I hope students can ask more imaginative questions and design creative experiments in the future. I hope that our experimental plan will enter the Tiangong in the future. "

Shenzhou 13 Lesson 2 Wang Yaping, the astronaut of the Shenzhou 13 flight crew, gave the first space lecture for more than 60 million primary and middle school students on Tiangong-1 during the Shenzhou 10 mission. Now, after a lapse of eight years, Wang Yaping once again serves as a space teaching lecturer at Tiangong Space Station, giving the "Second Space Class".

Wang Yaping's dream of flying came from China's first manned mission in 2003. With the launch of Shenzhou 5, Wang Yaping, who was already an air force pilot at that time, planted the dream of flying to a more distant universe.

Astronaut Wang Yaping: Looking at the brilliant tail flame when the rocket was launched, I suddenly had an idea of boiling blood. China has its first male astronaut. When will there be our female astronaut? At that moment, it can be said that the dream about the blue sky that has taken root in my heart has become more urgent. I also want to fly out of the atmosphere and see what space is like. I also want to contribute my bit to China's flying dream.

On 20 10, Wang Yaping was selected as the first female astronaut in China with her excellent flying skills and super psychological quality. June 20 13, together with Nie Haisheng and Zhang, she formed a Shenzhou-10 flight crew to explore space.

Astronaut Wang Yaping: There was really no fear in my heart at that moment. At that moment, there were only six words in my mind: responsibility, mission and dream interpretation.

In the Shenzhou-10 mission, Wang Yaping, Nie Haisheng and Zhang completed the first application flight of manned space flight in China, that is, the rendezvous and docking mission of Tiangong-1 and Shenzhou-10, and completed the first space teaching mission of China in Tiangong-1.

Astronaut Wang Yaping: I think teaching in space has created a new model and method of popular science education and primary and secondary education in our country. It can be said that it is the live broadcast of popular science education with the widest audience, the largest scale and the longest duration in the world.

Eight years ago, Wang Yaping stood on the highest platform in the world and used the special microgravity environment in space to carry out five scientific experiments, such as spring mass measurement, simple pendulum movement, gyro movement and making water-film water polo, which lasted for 40 minutes and planted the seeds of science and dreams in the hearts of countless teenagers.

Astronaut Wang Yaping: It also made me feel the significance of teaching in space. Some children fell in love with aerospace because of this, and some children entered the aerospace major because of this. Some children have even become my colleagues now, which is what makes me proud. What moved me particularly was that when I was teaching in space, the unborn children were still watching the videos of teaching in space that year, and they were still asking me, when will Miss Wang go to space again and give us another lecture in space? In fact, I think this has been encouraging me to fly into space again, so I think the mission time of the space station will be longer and the space will be bigger. I will definitely take my children to do science education again.

Wang Yaping, who returned to the post of "space teacher" for the first time in the space station stage, made full preparations and looked forward to bringing more wonderful "space second lessons" to children.

Astronaut Wang Yaping: Our space station is also an outstanding work of our motherland's space industry in the new era. It is our national laboratory flying in space orbit, so I also expect more China discoveries, more interesting human explorations and more brilliant China stories on our China Space Station. I also hope that our space station mission will be more exciting because of me.

Shenzhou 13 Lesson 3 The press conference of Shenzhou 13 manned mission was held at Jiuquan Satellite Launch Center on the afternoon of 14. Lin Xiqiang, spokesman for China's manned spaceflight project and deputy director of China's manned spaceflight project office, said that during the manned mission of Shenzhou XIII, astronaut Wang Yaping will give a "second space lesson" on the space station.

Lin Xiqiang introduced that during the Shenzhou-10 mission, when astronaut Wang Yaping gave a lecture in space, there were 60 million primary and middle school students in the ground class, and the social response was huge. Manned space flight is a space exploration activity in which people participate. As a national space laboratory, the space station contains unique and extremely rich popular science education resources, which has great attraction to the general public, especially teenagers. China Space Station is not only a research platform for global scientists to carry out space science, space technology and space applications, but also a practical platform to encourage young people to love space flight, participate in exploration and pursue science.

Lin Xiqiang said that on the basis of summing up and developing the beneficial experience of manned space science popularization, we have planned more diversified science popularization activities in this mission, and I believe that Wang Yaping will teach in space again soon. Here, I also hope that all sectors of society can actively make suggestions for the popular science cause of China's manned spaceflight project and put forward more wonderful project suggestions.

In addition, Lin Xiqiang introduced that in order to ensure the long-term flight, healthy life and efficient work of female astronauts, their physical characteristics and individual needs were analyzed.
