The goal for this target is to look for and measure seasonal changes due to wind-driven processes since an earlier HiRISE observation. There are high flux dunes upwind, but how do they compare to the downwind dunes? The dunes in this image are called “barchan dunes”, whose shape indicates the direction of the wind.
