Astronaut

An astronaut is a specially trained individual who travels into space to conduct research and perform missions in orbit around Earth or on other celestial bodies. They undergo rigorous training in various fields, including science, engineering, and physical fitness, to prepare for the challenges of space travel. Astronauts operate spacecraft, conduct experiments, and often engage in spacewalks to repair or maintain equipment. Their work contributes to our understanding of space, technology, and life sciences, and helps advance future exploration missions, including those to Mars and beyond.
