Seasonal fans pointing in multiple directions near Mars' south pole
Filed under Mars, Mars Reconnaissance Orbiter
Each spring, cold jets erupt from beneath a surface layer of carbon dioxide ice. Local winds can blow the dust from its source, forming a long fan. When the wind changes direction, a new fan is formed pointing in the new direction In this single image we can see that the wind has blown in a number of directions. This data will be used to study weather patterns near the South Pole.
