No Gravity

There is 90% as much gravity on a space station as on earth. Astronauts float about not because there is a lack of gravity, but because the space station is continually falling toward the earth, as it orbits, rather than shooting out in a straight line into space. The missing gravity effect is similar to the simulated lack of gravity when a jet does a steep dive.
