A space capsule is a type of spacecraft that is designed to transport astronauts, cargo, or scientific experiments to and from space. It typically has a streamlined, enclosed structure that provides a safe environment for its occupants during launch, re-entry, and landing.

Space capsules are often used for missions where reusability is not a primary concern, such as manned spaceflights to the International Space Station or beyond Earth orbit. They are usually equipped with heat shields to protect against the intense heat generated during re-entry into Earth’s atmosphere.

One of the most well-known examples of a space capsule is the Apollo Command Module used in the Apollo missions to the Moon. More recent examples include SpaceX’s Crew Dragon and Boeing’s CST-100 Starliner, both of which are designed to transport astronauts to and from the International Space Station.

Space capsules play a crucial role in human spaceflight, enabling astronauts to travel safely to space and return back to Earth.
