A method is disclosed for forming a shadow pattern on a planetary or lunar surface, including providing a rough terrain vehicle having a plurality of wheels capable of imparting to the planetary or lunar surface shadow shaping components to produce a shadow pattern capable of being seen from a distance; and controlling the rough terrain vehicle to produce a pre-designed pattern in the planetary or lunar surface, viewable from a distance when sunlight hits the shadow shaping components from an angle.
