Astronauts travel in space using spacecraft designed to operate in a vacuum, such as the Space Shuttle, Soyuz, or the International Space Station (ISS). These vehicles are equipped with life support systems to provide oxygen, temperature control, and waste management. Propulsion systems enable them to maneuver and change orbits, while launch vehicles (rockets) propel them into space from Earth. Once in space, astronauts may conduct missions, perform experiments, or explore celestial bodies.
