- from Space
Imagine what it would feel like to be weightless. You would float through the air, bouncing off the walls and ceiling.
Outside, you would have to hold on to something to keep from flying away. This doesn’t happen in everyday life, thanks to the pull of the Earth’s gravity.
Learning to be weightless is just part of an astronaut’s training. You need to do a lot to be an astronaut. You have to go to college. You need at least a bachelor’s degree in engineering, biological science, physical science, or mathematics. Plus, you have to have worked 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 tough physical test. And they need at least 1,000 hours of flying time.
