Space travel is the act of traveling through outer space beyond the Earth's atmosphere. This field of research involves the exploration and study of space, including the development of technologies to support human travel and habitation in space, such as spacecraft, spacesuits, and life support systems. Space travel also encompasses the planning and execution of missions to planets, moons, asteroids, and other celestial bodies within our solar system and beyond. Major organizations such as NASA, SpaceX, and the European Space Agency are actively involved in space travel research to advance our understanding of the universe and enable human exploration beyond Earth.
