Space flight, also known as space flight, space flight, space flight or space flight, refers to various 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 (also called 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 various application 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 by human beings outside the earth's atmosphere, such as high and remote positions in space, high vacuum, ultra-low temperature, strong radiation, microgravity environment, solar energy and material resources of celestial bodies outside the earth.

Second, the China spacecraft.

1, Shenzhou 5

1999165438+21year1October 20th to1October 20th, the flight test of China's first manned spaceflight project "Shenzhou" was a complete success. From the beginning of 2000/kloc-0 to the end of 2002, Shenzhou II-IV unmanned test spacecraft were developed and launched successively, and valuable test data were obtained, which laid a solid foundation for carrying out manned space flight. Shenzhou 5 spacecraft is a 1 manned spacecraft developed on the basis of unmanned spacecraft in China. It has 1 astronaut and runs in orbit 1 day. During the whole flight, we will provide the astronauts with necessary living and working conditions, and 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 parts, with a total length of 8860 mm and a total weight of 7840 kg. 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

Shenzhou VI manned spacecraft is one of China shenzhou spaceship series. "Shenzhou VI" and "Shenzhou V" have no difference in appearance. They are still three-cabin structures, namely, propulsion module, return module and orbital module. Their weight is basically maintained at about 8 tons, and they are 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.

3. Shenzhou VII

Huang Chunping, a member of the Chinese People's Political Consultative Conference (CPPCC), head of the advisory group of manned space rocket system, and commander-in-chief of Shenzhou 5 rocket, said that the launch time of Shenzhou VII will be delayed by about half a year, and the planned launch in 2007 will be postponed to 2008. Different from "Shenzhou V" and "Shenzhou VI", the development of "Shenzhou VII" rocket focuses on 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 the spacesuit have played an important role, and they will leave the cabin. Three astronauts, one walked out of the module, one met in the orbital module, and one stayed in the return module. Finally, they persisted and successfully completed this plan! Shenzhou VII was launched on September 25th, 2008 at 2 1: 10: 04.988 milliseconds. On September 28th, 2008 17: 37, the spacecraft successfully landed at the main landing site in Siziwangqi, Inner Mongolia, China, and successfully brought three astronauts, Zhai Zhigang (commander), Liu Boming and Jing Haipeng back to Earth. Shenzhou VII spacecraft flew for 2 days, 20 hours and 27 minutes.
