I could not find information of the International Space Station's position in space. I assume that it always has the same side towards Earth (the side where Cupola is), but which part of the ISS is leading? Or is there some rotation?

The ISS "flies" with the truss perpendicular to the flight path with the Russian segment trailing (Node-2 forward) and cupola facing earth. This is a LHLV (local horizontal-local vertical) attitude. To keep this attitude as it orbits the earth, the ISS actually has to rotate once per orbit, because a vehicle in orbit would stay fixed in the same attitude in inertial space.

Thanks for asking the question, I have often wondered about this myself.
