Crewed spacecraft are vehicles designed to transport humans into space. They are equipped with life support systems to provide air, water, and food for astronauts during their missions. These spacecraft can be launched into orbit around Earth or travel to other celestial bodies, such as the Moon or Mars. Examples of crewed spacecraft include the Apollo missions, which took astronauts to the Moon, and the International Space Station (ISS) vehicles that ferry crew members to and from the station. Modern spacecraft, like SpaceX's Crew Dragon, continue to advance human space exploration capabilities.
