Why, for any location on the surface of Mars, its satellites spend more time below the horizon than above the horizon?

| Due to the fact that the satellites are close to the surface of the planet, a smaller part of the orbit is always above the horizon. For an observer on the surface, the satellites pass through the visible part of the orbit with a greater angular velocity. In the polar regions, the satellites of Mars are not visible at all.
