How long do you have to study to become an astronaut? A: NASA requires its mission specialists and its commander and pilot astronauts to have bachelor's degrees in biological science, physical science, mathematics or engineering; most people take four years to earn these degrees.
Even in space... Becoming an astronaut is neither simple nor straightforward; there are no schools for astronauts or university courses. So how do you become an astronaut and what qualifications and qualities do you need? Space agencies are looking for the best people possible. Training an astronaut is a considerable investment for any agency; training is lengthy and expensive, and the support needed both before and during a space mission is costly.
