How did Buzz Aldrin train to go into space?

Buzz Aldrin trained for his space missions through a rigorous program that included physical fitness, technical training, and simulations. He underwent simulation exercises to prepare for the zero-gravity environment and practiced maneuvers relevant to the Apollo missions. Additionally, Aldrin participated in survival training and learned to operate the spacecraft systems and conduct scientific experiments. His background as a fighter pilot and his academic expertise in orbital mechanics also contributed to his preparation for space travel.
