What do astronauts do to prepare for space travels?

Astronauts undergo extensive training to prepare for space travel, which includes physical fitness, technical skills, and teamwork exercises. They participate in simulations to practice operating spacecraft and conducting experiments in microgravity. Additionally, astronauts undergo survival training for emergency scenariOS and learn about the systems and equipment they will use in space. Psychological training is also essential to help them cope with the isolation and confinement of long-duration missions.
