A space capsule is a type of spacecraft designed to transport humans and cargo to and from space. Unlike other spacecraft, which may have wings or other aerodynamic features, space capsules are typically rounded and built to withstand the intense heat and pressure of re-entering the Earth's atmosphere. They are often used in missions to the International Space Station (ISS) and for deep space exploration. Space capsules are equipped with life support systems to ensure the safety of astronauts during their journey. Notable examples include the Apollo capsules that took astronauts to the Moon and the Dragon capsule developed by SpaceX for resupply missions to the ISS.
