Shenzhou XII was successfully launched.
Chinese astronauts explore space again.
Yesterday (June 17) at 9: 22 am, the Shenzhou 12 manned spacecraft was launched by the Long March II F- 12 carrier rocket at Jiuquan Satellite Launch Center.
Three astronauts, Nie Haisheng, Liu Boming and Tang Hongbo, successfully went to the China Space Station and stayed in the Tianhe core module for three months.
After nearly five years, shenzhou spaceship went to war again. This is the 19 mission since the implementation of China's manned spaceflight project, and it is also the first manned mission in the space station stage, and its significance is self-evident.
Three astronauts gestured in the cabin to show that everything was all right.
These people who fly into space by spaceship are called astronauts. In the hearts of generation after generation, they have sown the seeds that they will also participate in exploring the vast universe in the future. Do you know the origin of the word "astronaut"?
The origin of the name "astronaut"
We are still called "astronauts", because we are divided into heaven, sea and air, so it is more standardized. "Astronaut" refers to a person who drives a manned spacecraft and engages in various jobs directly related to space missions. It is not only different from space crew, but also different from other people who go into space by spaceship, just as pilots are different from air crew and passengers.

"Dongfanghong No.1" commemorative stamp
1On April 24th, 970, China's first artificial earth satellite "Dongfanghong-1" was successfully launched, and the song "Dongfanghong, the sun has risen ..." was transmitted back to Earth from space through the "Dongfanghong-1" satellite, which opened the prelude for China people to explore the mysteries of the universe, use space peacefully and benefit mankind.
1970, 14 in July, with the approval of the central government, the development of manned spacecraft started. And began to select and train astronauts. "China Astronaut Research and Training Center undertook the task of selecting the first astronauts and set up a medical examination team.
Little known is the name "astronaut", which was put forward by Qian Xuesen. At that time, foreign countries were generally called "astronauts" or "astronauts".
The three astronauts on this mission
China Astronaut Research and Training Center is the third largest astronaut training center in the world, which is responsible for completing the whole process of astronaut selection and training, providing life support system for manned spacecraft and providing medical supervision and medical security for astronauts. Its predecessor was the Institute of Cosmic Medical Engineering.
The Institute of Cosmic Medical Engineering has twice faced the embarrassing dilemma of being cancelled. Fortunately, thanks to Qian Xuesen's support, the complete organizational system of the Institute of Aviation Medicine has been preserved, and the personnel have been streamlined, and the research focus of the Institute has shifted to the pre-research of aviation medical engineering.
In the early 1980s, Qian Xuesen participated in academic exchange activities in the institute almost every week, and gave specific guidance from academic ideas to technical methods for six years.
He keeps close communication with, Meilei, Liang and others. From the development of simulator to the research of space brain science, from the establishment of aerospace medical engineering discipline to the development of related equipment, he has put forward many original opinions and ideas.
In the Spring Festival of 2004, Yang Liwei, who just made history, went to visit Qian Xuesen with the person in charge of the manned spaceflight project. Qian Xuesen recognized Yang Liwei at a glance and encouraged him enthusiastically. "What you do now is more complicated than what I do, so you have surpassed me! Congratulations. "
On June 5438+ 10, 2006, astronauts Yang Liwei, Fei Longjun and Nie Haisheng visited Qian Lao.
Since then, every time a manned space mission is successful, astronauts will come to visit Qian Lao and listen to his teachings, which has become a practice.
Founder of China's space industry
Now, the world we are used to is only the most common world, and the range observed by scientific and technological personnel through various detection instruments is much wider than this world. Observations and scientific theories enable scientists and technicians to transcend our conventional world, enter the seabed several thousand meters deep, and go deep into the mantle and deeper core several Qian Qian meters below the crust. At the same time, scientists can also know the magnetic explosion caused by the solar wind hundreds of thousands of kilometers outside the earth. Understand the star world outside the solar system and the world hundreds of millions of light years away ... There are more than a dozen worlds in the minds of scientific and technological personnel, waiting for literary and art workers to create unprecedented literature and art with their most expressive methods.
-Qian Xuesen
Qian Xuesen, a Shanghainese, originally from Lin 'an, Hangzhou, Zhejiang Province, 1959 joined the China * * * Production Party. He is known as "the father of Chinese missiles", "the father of China rockets" and "the king of missiles". He is an outstanding scientist renowned at home and abroad and the founder of China's space industry.
Qian Xuesen studied in the United States and studied under the great scientist von Carmen. At the age of 28, he was already a world-renowned aerodynamist. 1955, Qian Xuesen returned to work, so China's missiles and atomic bombs were launched at least 20 years earlier. In the second year after returning to China, Qian Xuesen set up the first rocket and missile research institute in China, the Fifth Research Institute of the Ministry of National Defense, and served as the first president.
He presided over the completion of the "Building Jet and Rocket Technology" program, participated in the development of short-range missiles, medium-and short-range missiles and China's first artificial earth satellite, directly led the "two-bomb combination" test of medium-and short-range missiles carrying atomic bombs, participated in the "two-bomb combination" test of short-range missiles carrying atomic bombs in China, participated in the development plan of the first interstellar aviation in China, and developed and established disciplines such as engineering cybernetics and systematics in China.
Qian Xuesen's outstanding contribution, touching deeds and lofty character are precious spiritual wealth of our country and nation.
Qian Xuesen Library and Museum
Qian Xuesen Library was opened in Xuhui Campus of Shanghai Jiaotong University on 20112, the centenary of Qian Xuesen's birth.
"Dongfanghong No.1" Model in Qian Xuesen's Library
This scientist memorial hall has successively won the titles of National Patriotism Education Demonstration Base, National Popular Science Education Base, Shanghai Patriotism Education Base, Shanghai Popular Science Education Base and Shanghai National Defense Education Base. More than 6 1000 precious documents, manuscripts, photos and objects of Qian Xuesen were collected and preserved here, and an exhibition with the theme of "People's Scientist Qian Xuesen" of more than 3,000 square meters was arranged and displayed.
20 12 10, space hero yang Liwei visited Qian Xuesen library.
20 12 1 1, astronauts Jing Haipeng, Liu Wang and Liu Yang visited Qian Xuesen's library.
Friends who are fascinated by the unknown space may wish to come here and feel the space spirit of the founder of China's space industry. This weekend, Qian Xuesen Library also has two "hands-on activities in space", waiting for future astronauts to participate!

"Space practice" activity
1. Power generation energy conversion device
Age: 10- 14 years old
The activity will lead children to learn the principle of dry battery power generation and understand the whole process of power generation, namely chemical energy, electrical energy, mechanical energy and electrical energy.
2. Astronaut's "umbrella"
Age: 10- 12 years old
Planets in the vast universe have different environments. Some are too cold; Some are too hot; Some hydrogen and methane almost filled the whole atmosphere, making people unable to breathe. Humans overcame these harsh environments with their own wisdom and created astronauts' umbrellas-spacesuits. In this activity, children will learn about astronauts' spacesuits and design and make their own space helmets.
