1. 航天器可以分为无人航天器和载人航天器两大类。无人航天器根据是否围绕地球运行，分为人造地球卫星和空间探测器。
2. 人造地球卫星， commonly known as artificial satellites, are the most numerous type of spacecraft, accounting for more than 90% of the total number of spacecraft. They can be further classified based on their purposes and flight paths.
3. Scientific satellites are used for scientific exploration and research, primarily including space physics exploration satellites and astronomical satellites.
4. Application satellites are designed to serve the national economy and military directly. They can be categorized into communication satellites, weather satellites, reconnaissance satellites, navigation satellites, geodesy satellites, Earth resource satellites, interceptor satellites, and multi-purpose satellites based on their uses.
5. Space probes, also known as deep space probes, are categorized based on their target of exploration. They include lunar probes, planetary probes, and interplanetary probes. Various planetary and interplanetary probes are used to explore Venus, Mars, Mercury, Jupiter, Saturn, and interplanetary space.
6. The United States launched the Pioneer 10 probe in March 1972, which in October 1986, passed the average orbit of Pluto, becoming the first spacecraft to leave the solar system.
7. Manned spacecraft, space stations, and space shuttles are the three types of spacecraft based on their flight and operational methods. Satellite-type manned spacecraft and lunar manned spacecraft are included in the category of manned spacecraft.
8. Space shuttles are not only spacecraft but also reusable space carriers. So far, the United States, the former Soviet Union, China, and India have achieved spacecraft launches.
