It's easy to assume that astronauts float in space because they are far away from the Earth's gravitational force. But look at the moon. It is much further away than the International Space Station, yet it orbits around the Earth because it is perpetually attracted by its gravitational pull. So if the Earth's gravity can affect the moon, the astronauts cannot be floating because there is no gravity where they are.
