Dust Fans on the Seasonal Carbon Dioxide Polar Cap

Dust Fans on the Seasonal Carbon Dioxide Polar Cap
Caption throwback (2007): As the sun comes up in the spring, the ice evaporates in a complex way. This observation shows dark dust being blown across the seasonal south polar cap. The dust comes from the surface beneath the ice: it either starts at spots bare of ice, or it’s possible that it’s lofted from below the ice in geyser-like plumes. (Read the full caption.)
