Astronauts are really far out! As professional space travelers, they are the commanders, pilots, and crew members of spacecrafts. They conduct missions, research, and experiments in space. Some famous astronaut missions include the moon landing, the repair of the Hubble Space Telescope, and frequent trips to the International Space Station. In addition to having a degree in science or engineering, you must also go through very intense training including tests of physical, psychological, and mental ability. Do you think you could handle floating in zero gravity?
