NASA chooses its astronauts from an increasingly diverse pool of applicants that, 'looks like America". From thousands of applications from all over the world, approximately 100 men and women are chosen for an intensive astronaut candidate training program every two years. "I cannot imagine a better career. I've done more than I could ever have imagined. I'm thankful that I've been at the right place at the right time," said Kenneth S. Reightler.
The study time involved is no more lengthy than that of any other professional career requiring graduate/post-graduate study. If becoming an astronaut is a dream, held long and steadfast, than this labor will be one of love.
