What NASA Requires of Their Astronauts
Professional astronauts go through vigorous training and have to handle many physical challenges in order to travel to space and be employed by NASA. Being an astronaut takes intense endurance and stamina.
NASA is constantly on the lookout for new astronauts and usually selects 15 to 25 applicants every two years. Currently, there is no age limit, but candidates must also pass the NASA space flight examination test.
All candidates must have a Bachelors of Science from an accredited institution and have at least 1,000 hours of pilot in command time. They must pass a physical exam and have excellent vision. There are different requirements for different positions, but they will require the applicant to be in good to top physical condition, to withstand the stresses of space flight.
Once selected, applicants undergo training for an entire year at Johnson Space Center in Houston, Texas. Johnson Space Center is where astronauts are schooled in flight training, survival training and basic mission testing.
What astronauts do in space is actually risking their lives to further give us a greater knowledge and awareness of space. Exploration and research of space would not be possible without the courage and efforts of the men and women who take up this monumental task.
