It's possible that the grooves in this video were created by the Mars rover itself. The rovers, such as the Curiosity rover, have instruments and tools on board that can interact with the Martian surface and potentially create such patterns unintentionally. Mars rovers are equipped with tools for collecting samples of Martian soil and rocks. These tools may include drills or scoops that can interact with the surface, creating small grooves or disturbances in the sand as they collect samples. When a rover drills into a rock, it creates a borehole. The process involves the rotation and downward movement of the drill bit, which can result in the accumulation of drilled material around the borehole's perimeter, creating a groove-like appearance. The sampling and drilling activities of Mars rovers like Curiosity involve direct interactions with the Martian surface. These interactions can lead to the creation of small-scale grooves, marks, or patterns in the sand like you saw in this video.
