A spacecraft is a vehicle designed for travel or operation in outer space. It can be used for various purposes, such as exploring other planets, studying stars, or even transporting astronauts. Some well-known spacecraft include the Apollo missions that took humans to the Moon and the Mars Rover that explores the surface of Mars. Spacecraft can be divided into two main types: crewed and uncrewed. Crewed spacecraft, like the International Space Station, carry astronauts who live and work in space. Uncrewed spacecraft, such as satellites, gather data and send it back to Earth without any human presence. Both types play crucial roles in advancing our understanding of the universe.
