Astronauts float in space because they are in a constant state of free-fall. This is due to the fact that while the astronauts are in orbit around the earth, they are falling towards the earth due to its gravity. However, because they are moving forward at such a high speed, they keep missing the earth. This constant falling is what causes the sensation of weightlessness or floating. It's not that there is no gravity in space, in fact, astronauts are still under the influence of Earth's gravity, but they are falling at the same rate as their spacecraft, so it appears as if they are floating. Their weight is not zero, it's just that the effect of gravity is being counteracted by their constant state of free-fall.
