According to NASA, astronaut candidates must have “at least three years of related, progressively responsible, professional experience or at least 1,000 hours of pilot in-command time in jet aircraft.”
Astronauts must be highly trained, skilled professionals with a tremendous desire to learn about outer space and to participate in the highly dangerous exploration of it. They must have a deep curiosity with extremely fine and quick reactions. Astronauts may have to react in emergency conditions that may never before have been experienced, and to do so they must be able to remain calm and to think quickly and logically. As individuals they must be able to respond intelligently to strange and different conditions and circumstances.
