NASA Gets Record Number of Astronaut Applications

An unprecedented number of Americans think they have the right stuff.

— -- More Americans than ever think they have the "right stuff" for space travel.

While many applied, few will be chosen. An 18-month process will help NASA determine which 8 to 14 people will earn the chance to become an astronaut candidate.

Officially, all applicants need in order to apply is a bachelor’s degree in engineering, biological or physical science, or mathematics, plus just three years of professional experience or 1,000 hours of pilot time.

Candidates will have to to pass the space physical, which restricts would-be astronauts to men and women no taller than 6-feet 4-inches. They'll also go through rigorous training on spacecraft systems, spacewalking, team dynamics and the Russian language, among other skills.
