Well as you could see in the movie "Interstellar", once you have left the earth you can just zip around everywhere with your little space dinghy :-)

- sytelus 12y agoI don't know if lot of people realize this but you don't "leave" Earth just in low orbit or even significantly higher up. In fact the actual gravitational force at the level of ISS is almost same as on surface. The reason you "feel" zero gravity is not because you are so far from Earth but because you have acquired so much velocity that you fall with same acceleration as other falling objects. This is equivalence principal that creates feeling of weightlessness. But objects at that height otherwise feel pretty much same pull of gravity as us on surface.
