Selection & Training of Apollo Astronauts

Selection and Training of Apollo Astronauts

Images of astronauts imprinting the first human footprints on the moon often spring to mind when contemplating space exploration and the Apollo missions. But to even qualify for these historic endeavors, astronauts first had to navigate the hurdles of a stringent selection process and complete comprehensive training.

The Selection Process

Potential Apollo astronauts were initially selected from a pool of military test pilots, and later civilian scientists and engineers were also included. To even be considered for selection, a candidate had to meet several criteria. Firstly, they had to be less than 40 years old and have a height of no more than 5 feet 11 inches due to the compact nature of the Apollo spacecraft.

Physical health was another big factor in the selection process. The candidates underwent thorough medical examinations to ensure that their bodies could stand up to the rigors of space travel. This included cardio-respiratory tests, psychiatric evaluations, and neurological assessments to ensure both physical and mental soundness.

Once the medical tests were passed, the next part of selection focused on skills and experience. Most of the astronauts selected had backgrounds in engineering or the natural sciences, as they would be conducting experiments and troubleshooting technical problems while in space. They also had to demonstrate exceptional flying skills, leadership abilities, and a level-headed temperament during high-stress situations.
