Function:
1. Scientific satellites: satellites sent into space orbit for atmospheric physics, astrophysics and geophysics experiments or tests, such as China Satellite 1 and Hubble.
2. Communication satellite: a satellite as a telecommunication relay station, such as Yahweh-1.
3. Military satellite: a satellite used for military photography and reconnaissance.
4. Meteorological satellite: a satellite that captures cloud images and related meteorological data.
5. Resource satellite: a satellite that takes images of the surface or deep layers and uses them for earth resource exploration.
6. Interstellar satellites: Satellites that can sail to other planets for exploration and photography are generally called planetary detectors, such as Pioneer, Mars and Pathfinder.
It has been more than 40 years since data inflation. Today, China has dozens of satellites roaming in space, the Shenzhou experimental spacecraft has returned to Earth, and China has taken a step towards manned space flight. Looking back on the history of China's space flight, we can't help but mention its beginning. Dongfanghong-1, a sophisticated technology, was successful in one fell swoop in a period of poor foundation and turbulence.
From1April 24th, 970 to1October 3rd, 20001day, China launched 74 spacecraft, covering four kinds of orbits owned by the earth. Among them, the domestic experimental spacecraft 1, 47 domestic artificial satellites and 26 foreign-made satellites. At present, 47 domestic satellites are the mainstay.
