Tiangong second classroom after watching 500 words 6 articles

I believe that after watching the "Tiangong Second Classroom" space lectures, students are full of yearning for space, and at the same time, they have planted the seed of space dream in their hearts. The following is my compilation of the second classroom of the Tiangong 500 words after watching, welcome to learn and reference!

The second classroom in the Tiangong 500 words after viewing 1

From Shenzhou V to Shenzhou XIII, from one person for one day to three people for half a year, the Chinese people running to the stars and the sea has never stopped.

More than half a century ago, a song "Oriental Red" resounded throughout the world. Nowadays, the bright red of China shines in space. From "two bombs and one star" to "manned spaceflight", the "space dream" has long been merged into the great "Chinese dream". It has become a stunning stroke in the development of human civilization.

"Chang'e" to the moon, "Beidou" to guide the way, "Tianwen" to ask the sky, "Tiangong" to visit the victory, "Jade Rabbit" to see and "Jade Rabbit" to explore the moon, "Zhu Rong" to explore the fire, "Xihe" to explore the sun ...... A mission full of the deep cultural heritage and cultural heritage of the Chinese nation. The task of cultural heritage and cultural heritage, once and for all demonstrated the exploration achievements of China's aerospace courage to climb the peak of science and technology, showing the great Chinese road, the spirit of China, China's power.

The Chinese people's exploration of the infinite universe is a new journey for a strong nation. The Chinese people's exploration of the boundless universe is never-ending. The first step in the process is to make sure that you have the best possible chance of getting to the top of the list, and that you have the best possible chance of getting to the bottom of the list. Behind every step of innovation and breakthroughs in the space journey, are inseparable from the generations of astronauts hard work, unremitting struggle, independent innovation, become a country and a nation of *** with the memory.

Another year of golden October, another time the dream of the family and the country is complete. This space trip, not only can refresh the Chinese people in space residence time record, further carry out more space science experiments and technology tests, output high-level scientific results, we can more and they experience in space together over the Spring Festival ...... scientific exploration once again with the space dream in space to play a concerto.

"The dream of flying in space is never weightless, and the tension of the scientific dream is infinite." As female astronaut Wang Yaping said before her departure, as long as you dare to have a dream, the courage to pursue the dream, with wisdom and sweat to build their own dream spaceship, you will be able to usher in the launch of their dream moment, flying to the vastness of the starry sky belonging to you!

The "selection" of the conditions of space lectures is that the materials and equipment needed for the experiment must be safe and reliable, small quality, small size, small power consumption, no impact on the health of the astronauts, and will not pollute the environment of the cockpit; of course, it is also necessary to consider the novelty of the creative ideas. Of course, it is also necessary to consider the creative novelty, simple and feasible, do not need to spend a lot of time astronauts and other factors.

"At that time, a magnet experiment was also designed, but considering that the magnet may have an impact on the spacecraft internal instruments and equipment, so this experiment was abandoned." Pang Zhihao added, in addition, chemical experiments have a certain degree of danger, in order to be safe, chemical experiments in space are usually carried out in the laboratory cabinet or glove cabinet, it is difficult to present to students on the ground, so the selection of physical experiments as the content of space lectures is more secure and visualization.

In order to do a good job of China's first space instruction science education activities, the China Manned Space Engineering Office, together with the Ministry of Education, China Association for Science and Technology and other departments of the activities of the system, thorough planning, completed the courseware, teaching aids production and ground classroom preparation, the astronauts are also prepared for this special.

As Tiangong 1 is a precision vehicle, the astronauts must be careful in their teaching activities, not only can not move too much to interfere with the normal flight, but also beware of floating experimental equipment, liquid droplets affecting the safety of the spacecraft.

As the main speaker of the astronaut Wang Yaping, in the preparation of the lesson did not make much effort. She meticulously prepared the content of the lecture, to the professional teachers humbly ask for advice on the skills of lecturing. Astronaut Zhang Xiaoguang was almost "tied" to the bulkhead to listen to the class, because as a cameraman, he wanted to maintain balance in a weightless environment, he had to use a harness to fix himself on the bulkhead, so that he could use a hand-held camera to maintain a long period of stable shooting, and send the wonderful images of the space lectures back to the ground classroom.

"Future space lectures will have more and more novel experimental content and forms. For example, the heaven and earth comparison experiment, comparing the difference between silkworms or spiders spitting silk in space and on the ground, observing how butterflies flutter in space, etc." Pang Zhihao introduction, China's relevant departments have also begun to organize the design of space experiments for young people, and regularly invited experts to review, excellent experimental program is expected to be implemented on the Chinese space station in the future.

China's first space lecture activity lasted about 40 minutes. This day-to-day interactive process is realized with the support of China's relay satellite, and its debut at the same time marks the basic completion of China's new generation of manned spaceflight measurement and control network.

"Ground Internet class, the most difficult is a smooth network, in the sky this problem is even more difficult to ensure." Yang Yuguang said, how to ensure high bit rate, high fidelity video streaming communication link completely smooth, is the process of space lectures challenges, difficulties, uncertainties in the most links.

Yang Yuguang further explained that space lectures of high-definition video transmission, our country mainly rely on the high altitude of the sky chain relay satellite for support, to the ground measurement and control station, the surface of the sea, the Far Sight measurement ship as a backup, but the ground measurement and control support ratio is not high, this is because the Tiangong 1, the space station most of the time is not in the air above the mainland of China.

A basic principle of radio communication is that the higher the transmitted data code rate, the higher the energy consumption of the transmission and the higher the sensitivity requirements of the transmission equipment.

"Space lectures require higher code rates for audio and video." Yang Yuguang explained that for this reason, the sky chain relay satellite uses a high-gain antenna, making the beam very narrow to ensure that the energy is concentrated and the smooth transmission of high bit rate video data. The other end of China's space station is set up on the butterfly antenna, pointing to the relay satellite to cooperate. In this way, theoretically at any time there is a relay satellite can "see" our space station, to ensure that the teaching process of smooth communication. "The time delay of space lectures is only about 0.3 seconds." He said.

Not only that, the space instruction and the full elements of the rehearsal before the instruction, all involving a wide range of heaven and earth collaborative work.

"When Wang Yaping gave his first space lecture in 20__, the Ministry of Education was responsible for organizing the students, the China Association for Science and Technology was responsible for designing and preparing the curriculum, and the China Manned Space Engineering Office was responsible for the astronauts and the communication system." Pang Zhihao said.

"The measurement and control communication system for relay star switching is also an important heaven and earth synergy. In addition, Wang Yaping demonstrated the physics experiment in the sky, the ground teacher is also doing the same experiment, heaven and earth comparison experiments are almost synchronized in the video screen." Yang Yuguang said.

I like the beautiful and eye-catching Chinese knot hanging in the "Tiangong" space station, which is facing the bright five-star red flag. Such a space station is the most beautiful scenery in space, and makes us feel more intimate.

In space to control their own bodies to adapt to the sense of weightlessness, like a fish to swim around. The meals you eat turn out to be pre-made on Earth. Cultivating space plants is an important part of the mission.

In space, although you can't take a hot shower like on Earth, there is no problem washing your face and hair. Researchers have developed a special decomposition shampoo - not only can you wash your hair clean, but it also saves a lot of water. Water on the space station is very precious, so it's important to conserve it as much as possible.

Sleeping on the space station is even more fun. All you need is a sleeping bag, which is generally required to be secured to the bulkhead, but you can sleep anywhere you want, like on the ceiling.

There are also many leisure activities on the space station, you can make video calls to your family, you can enjoy the beautiful Earth at sunset from the porthole, and you can have a morning exercise, which is a traditional Chinese fitness program - tai chi.

The most important and exciting thing is to get out of the cabin. Wear a good "flying" suit, through the airlock cabin to the cabin, through the ground scheduling staff and cabin companions *** with the efforts to successfully complete the relevant tasks outside the cabin.

In space there are also many happy events: the planting of rice, ushered in the space courier, but also ushered in a new partner to carry out the work of the transition. After three months in space, we are going to say goodbye to the Tiangong space station and return to Earth, and we are very excited to see our loved ones on Earth.

Space itself has been very fascinating, in the vastness of the universe, every time there is a five-star red flag with everything, are more and more so that every child of China doubly intimate and proud!

Shenzhou XIII this "highlights" are quite a lot: compared to the Shenzhou XII stay in space for three months, this time it is half a year, the three astronauts will be in space in the Chinese New Year, the Earth will be the first time we will experience the new year's blessings from space. Received from the space of the New Year's blessings; this is the first time that Chinese female astronauts stationed in China's space station, astronaut Wang Yaping will also become China's first implementation of the cabin activities of female astronauts; this time will be the use of autonomous rapid rendezvous and docking, the first radial docking space station; the manned mission will be carried out in 2 to 3 times out of the cabin activities, etc.

The manned mission will be carried out in the space of the Chinese space station, and will be the first time in the Chinese space station.

From Shenzhou I to Shenzhou XIII, from 2003 Yang Liwei as China's first astronaut into space to realize the Chinese nation's millennium dream of flying, to now China has 12 people have been to space, China's space industry is striding forward. The ambitious project of space station construction will be completed step by step in an orderly manner, and we firmly believe that it will be carried out successfully in the future; the space dream, which is related to the peace and progress of mankind, will become a reality through the unremitting efforts of generations of Chinese astronauts, and we are full of confidence in this.

For the Chinese people, behind this excitement, more is a calm. The decades of aerospace, behind which is the road of national rejuvenation. We have experienced our own country's struggle, and we also feel the country's ever-changing progress in the changes of daily life.

In the future, we will witness the launch of Shenzhou XIV, Shenzhou XV, and so on. Every time we witness this, it strengthens the people's confidence in the country and in the future. The growing strength of science and technology is an indisputable fact, and it is a change that the people can see and feel, not just a fantasy. Therefore, this is not only a story of Chinese astronauts' succession from generation to generation and the inheritance of their dreams, but also a story of the people's greater confidence, the country's greater strength, and the nation's greater hope.

We can't help but look back at the past, and the more we look back at history, the more we can understand the present. The more we look back, the more we cherish. We will keep reviewing every important node of China's science and technology endeavors, looking for the driving force of the nation's forward movement in these milestone events. Those moments, because of remembering, become eternity.

The Tiangong is a space station independently developed by China. You don't say, "Tiangong" this name is not randomly set, it is like a palace, all kinds of things.

The space station is a short-term accommodation for astronauts, and can do a variety of space research and experiments in the "space hotel-style laboratory". Why build a space station? The space station can test a variety of technical equipment that may be used for space flight in the future. They also provide access to "weightless" environments - special environments that are difficult to obtain on the ground for long periods of time. However, the cost of a round trip to space is quite high, and being able to spend more time in space at a time can increase efficiency while reducing costs. So the idea of a fully functional place where astronauts could stay longer was born.

First, let's start with the plan for our "palace".

The sky and core modules are the bedrooms of the palace, mainly for the astronauts to live in. Cargo and manned spaceships are like vehicles on the ground, used to transport goods and people. Ask the sky experimental module and dream sky experimental module is not yet completed, they are the "palace" in the research and development laboratory, used for a variety of space experiments and scientific research work.

There are all sorts of conceivable dangers in space, and one of them comes from what we know as the Sun. As we all know, the Sun is the source of life on Earth, providing an unending supply of all kinds of energy that nourishes everything. But it releases _rays and gamma rays that are very deadly, both of which can easily penetrate your skin and destroy all the cells in your body. So why can we get sunshine every day on Earth? That's because the Earth's magnetic field and atmosphere reflect or absorb them. The location of the space station must take this safety factor into account. The international community generally chooses a location 1,000 kilometers from the ground, our "Tiangong", in order to degree of safety, set up in a location 400 kilometers from the ground. This can obtain both the protection of the Earth's magnetic field, but also to obtain the protection of the atmosphere, two birds with one stone.

In ancient times, the Heavenly Palace was said to be in the clouds, where all kinds of gods and goddesses lived, indistinct, invisible and untouchable. Today's "Heavenly Palace" lived many astronauts and scientists, they are high in the sky for China's space technology progress, and constantly strive to make us no longer rely on foreign technology, overlooking the Earth at the same time can really look at the entire universe, the understanding of space is constantly deepening.

So, our "Tiangong" is really a veritable palace in the sky ah! Perhaps this is the origin of the name "Heavenly Palace" and the good meaning of it.

"Heavenly Palace" has opened the door to the clouds, traveling in space, the future can be expected!
