Dust levitation as a major resurfacing process on the surface of a saturnian icy satellite, Atlas

► Atlas is covered by fine particles, which explains its unusually-smooth appearance. ► Fine particles are accumulated from A-ring, forming the enigmatic shape of Atlas. ► The fine particles on Atlas electro-statically levitate, migrate, and eventually deposit. ► This process is working globally and erasing surface features, including craters.
