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.
Space can be dangerous. Astronauts need a space suit that protects them from extreme hot and cold. The space suit must have air so that astronauts can breathe. Astronauts can work outside in space if they're wearing a spacesuit. Maybe one day you'll be able to go to space on holiday! Scientists are working on spaces suits that tourists can wear.
