10. How do you keep from hitting the ceiling? Is there an up and down? Would there even be any floors and ceilings? (A K2S Question)

From The Space Library

You actually can hit any and every surface, if you are not careful. The best thing to do is to move slowly and make sure that you can grab onto some part of the ship to steady yourself. There are all the normal surfaces—floor, walls, and ceiling—but without an up or down, they don't have the same meaning. In the Space Shuttles that I flew on, we actually had some control panels upside down, as they were near the floor, and we would operate them with our heads toward the floor.
