Imagine what it would feel like to be weightless. You would float through the air, bouncing off the walls and ceiling. If you were outside, you would have to hold on to something to keep from flying into the sky.
This doesn’t happen to us in everyday life, thanks to the pull of the Earth’s gravity.
Learning to live with weightlessness is just part of an astronaut’s training. You also need education and experience to become an astronaut. You need at least a bachelor’s degree in engineering, biological science, physical science, or mathematics. Plus, you have to work in your field for at least three years. Spacecraft pilots must be between 5 feet 2 inches and 6 feet 3 inches tall. They have to pass a strict physical exam. And they need to log at least 1,000 hours of flying time.
