Crewed space missions involve sending astronauts into space to conduct research, exploration, and various scientific experiments. These missions are typically launched aboard spacecraft, such as the Space Shuttle or the International Space Station (ISS), where astronauts can live and work in a microgravity environment. The primary goals of crewed missions include advancing our understanding of space, testing new technologies, and preparing for future exploration of other celestial bodies, like Mars. Notable crewed missions include the Apollo program, which successfully landed humans on the Moon, and ongoing efforts to maintain and expand the ISS.
