HiRISE PICTURE OF THE DAY: 15 APRIL 2026
Downwind of the Barchan Dunes
The science rationale for this beautiful image is to look for and measure seasonal changes due to wind (aeolian) processes since an earlier image we acquired. High flux dunes upwind, but how do they compare downwind? The “horns” of these barchan dunes point in the direction of the prevailing wind.
