Pilot astronauts are specially trained individuals who operate spacecraft during missions. They are responsible for navigating and controlling the vehicle, ensuring it reaches its destination safely. These astronauts often have backgrounds in aviation, engineering, or science, which helps them manage complex systems in space. In addition to flying the spacecraft, pilot astronauts work closely with mission control and other crew members. They conduct experiments, monitor equipment, and respond to emergencies. Their training includes simulations and physical conditioning to prepare for the challenges of space travel, such as microgravity and radiation exposure.
