Pilot astronauts also need flight experience. You can send in an application at any time, but NASA only selects every two years. About one in 20 applicants are called for a week of interviews. Among other things, interviewers want to see how well you get along with others, think for yourself and have a wide range of skills. Perseverance Only about one in 120 applicants are accepted.
Many astronauts apply more than once.
Many wannabe astronauts become flight controllers or get other jobs at the Johnson Space Center in Texas. That way, they not only get a chance to work in the space industry, they also can demonstrate how they shine on the job. The NASA training program tries to get astronauts as close as possible to being in space without leaving the ground. Trainees study science, math, space-shuttle operation and scuba diving. In full-size models of the shuttle and space station, trainees practice skills that include taking out the trash and making dinner.
