I have started this orbital space station the comcept is landings pads for big ships on center and little ships on top i have to decide if is need to put a ring outside or are enought solar panels
Does it rotate?
In my opinion, a station need lots of power. If it doesn't have a generator, I imagine it with many panels always orientated towards the sun, attached far from the docking area to not intefere the docking ships and the ships that are waiting for the permission to dock.
In a station that rotates to make 'gravity', up is the direction to the axis of rotation and down is the direction away from it. It's something that is often portrayed wrong in science fiction, with windows that would be in the floor. I'm not sure if that's the case here.
