Ask an Explainer

Q:

How can I become an astronaut?

A:

Becoming an astronaut is a very long process. First, NASA has several requirements before official training begins. Candidates must have a degree in engineering, biological science, physical science, or mathematics. Pilot candidates also must have at least 1,000 hours of experience flying jet planes. Next, candidates need to be healthy, have good vision, and be between 1.5 and 1.9 meters (58.5 and 76 inches) tall. Lots of people send applications to NASA, but only a few are chosen each year for the Astronaut Candidate program. During this two-year-long program, candidates have to pass many difficult tests, but if they succeed, they can go to the International Space Station!
