Abstract: The grooves on the surface of asteroid 951 Gaspra are fractures modified by the inward drainage of regoliths with depths ranging from 30 to 200 meters. The regoliths are noncohesive substances of various sizes. The presence of grooves indicate that Gaspra was subjected to violent collisions with other astronomical objects.
