A spacecraft is a vehicle designed for travel or operation in outer space. It can be used for various purposes, including exploration, research, and communication. Spacecraft can be manned, carrying astronauts, or unmanned, operated remotely or autonomously. They are equipped with systems for navigation, communication, and life support, depending on their mission. There are different types of spacecraft, such as satellites, space probes, and space shuttles. Satellites orbit Earth and provide services like weather monitoring and GPS. Space probes travel beyond our solar system to gather data about other celestial bodies. Space shuttles were used to transport astronauts and cargo to and from space stations like the International Space Station.
