Astronaut candidates must meet several physical requirements, including: Specific physical restrictions for height, weight, and body size may be put in place for astronauts because they must fit into a spacesuit and spacecraft. After completing basic training, astronauts then get the opportunity to go where very few have gone: Deep space.
