What are the components of space technology?

Space technology includes three important components: launch vehicle, spacecraft and ground measurement and control technology.

1, carrier

The vehicle is mainly a launch vehicle. The launch vehicle has several parts, such as airframe structure, propulsion system and control system. Because the propellant used is chemical propellant, single-stage rocket can't put satellites and spacecraft into orbit.

2. Spacecraft

There are many kinds of spacecraft, mainly artificial earth satellites, as well as space stations, spaceships, space shuttles and space probes.

3. Ground measurement and control technology

The ground measurement and control system tracks, measures, controls and maintains communication with spacecraft on the ground. Through the ground measurement and control system, people can get all kinds of information about the operation of spacecraft, and can control and adjust its operation state to achieve people's expected goals.

Space technology is a technology for exploring, developing and utilizing space. It is a comprehensive science and technology, involving the design, manufacture, launch and application of various spacecraft. Manned space flight is the frontier of space technology.

Extended data

Spacecraft, also known as spacecraft, is the general name or space system of all kinds of aircraft that run in space and complete certain tasks according to the laws of celestial mechanics. 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.
