I. Understanding Spaceflight

Space flight, also known as space flight, space flight or space flight, refers to all kinds of activities of entering, exploring, developing and utilizing space (that is, space outside the earth's atmosphere, also known as outer space) and celestial bodies outside the earth.

Space activities include space technology, space application and space science. Space technology refers to a comprehensive engineering technology that provides technical means and guarantee conditions for space activities. Space application refers to all kinds of applied technologies in scientific research, national economy, national defense construction, culture and education by using space technology and its developed space resources. Space resources refer to all kinds of environment, energy and material resources that can be developed and utilized for human beings outside the earth's atmosphere, such as high and far position in space, high vacuum, ultra-low temperature, strong radiation, microgravity environment, solar energy and material resources of celestial bodies outside the earth.

II. China Spaceship

1. Shenzhou 5

On November 2-21, 1999, the flight test of the first unmanned Shenzhou spacecraft in China's manned spaceflight project was a complete success. From the beginning of 21 to the end of 22, Shenzhou 2 ~ 4 unmanned test spacecraft were successively developed and launched, and valuable test data were obtained, which laid a solid foundation for carrying out manned space flight. Shenzhou-5 spacecraft is the first manned spacecraft developed on the basis of unmanned spacecraft in China. It has an astronaut and runs in orbit for one day. During the whole flight, we will provide the astronauts with necessary living and working conditions, and at the same time send the astronauts' physiological data and TV images to the ground to ensure the astronauts' safe return.

the spacecraft consists of orbital module, return module, propulsion module and additional sections, with a total length of 886mm and a total weight of 784kg. The manual control function of the spacecraft and the subsystem of environmental control and life support provide a guarantee for the safety of astronauts.

2. Shenzhou VI

The Shenzhou VI manned spacecraft is one of the shenzhou spaceship series in China. "Shenzhou VI" and "Shenzhou 5" have no difference in appearance, and they are still three-cabin structures of propulsion module, return module and orbital module, with the weight basically kept at about 8 tons, and were launched by the Long March II F carrier rocket. It is the second spacecraft carrying astronauts in China and the first manned spacecraft in China to carry out the "multi-person and multi-day" mission.

Huang Chunping, member of Chinese People's Political Consultative Conference of Shenzhou VII, head of the advisory group of manned space rocket system and commander-in-chief of Shenzhou V rocket, said that the launch time of Shenzhou VII will be delayed by about half a year, and the original launch plan for 27 will be postponed to 28. Different from "Shenzhou 5" and "Shenzhou VI", the key points in the development of "Shenzhou VII" rocket are spacesuit and airlock. Because "Shenzhou VII" will realize the spacewalk, whether the astronauts can adapt to the vacuum environment suddenly from the cabin pressure, the airlock cabin and spacesuit have played an important role, and they have to leave the cabin. Three astronauts, one to walk out of the cabin, one to meet in the orbital module, and one to stay in the return module, finally persisted and successfully completed this plan! Shenzhou VII was launched at 21: 1: 4.988 ms on September 25th, 28. At 17: 37 on September 28th, 28, the spacecraft successfully landed at the main landing site of Siziwangqi, Inner Mongolia, China, and successfully brought three astronauts, namely Zhai Zhigang (commander), Liu Boming and Jing Haipeng back to Earth. The Shenzhou VII spacecraft flew for 2 days, 2 hours and 27 minutes.
