A space capsule is a type of spacecraft designed to transport humans and cargo to and from space. Unlike other spacecraft, which may burn up upon re-entry, space capsules are built to withstand the intense heat and pressure of returning to Earth's atmosphere. They typically have a rounded shape, which helps to minimize drag and protect the contents inside. Space capsules are often used in missions to the International Space Station (ISS) and can be launched atop rockets like the SpaceX Falcon 9 or the NASA Space Launch System. Notable examples include the Apollo capsules that took astronauts to the Moon and the Crew Dragon used for modern space travel.
