NASA astronauts are highly trained professionals selected by NASA to operate spacecraft, conduct scientific research, and perform space missions. They undergo rigorous training in areas like engineering, medicine, and survival skills to prepare for living and working in space environments, including the International Space Station and future missions to the Moon or Mars. Their work advances scientific knowledge, develops new technologies, and ensures safety during space exploration. Astronauts must demonstrate physical fitness, teamwork, problem-solving abilities, and adaptability to handle the challenges of space travel. They represent humanity's efforts to explore beyond Earth and expand our understanding of the universe.
