English: June 11, 2018 - Once in a Blue Dune - Enhanced Color
https://www.jpl.nasa.gov/spaceimages/details.php?id=PIA22512 In this region of Lyot Crater, NASA's Mars Reconnaissance Orbiter shows a field of classic barchan dunes. Sand dunes often accumulate in the floors of craters on Mars. Map Projected Browse Image Click on image for larger version Sand dunes often accumulate in the floors of craters. In this region of Lyot Crater NASA's Mars Reconnaissance Orbiter (MRO) shows a field of classic barchan dunes. Just to the south of the group of barchan dunes is one large dune with a more complex structure. This particular dune, appearing like turquoise blue in enhanced color, is made of finer material and/or has a different composition than the surrounding. The map is projected above at a scale of 25 centimeters (9.8 inches) per pixel. [The original image scale is 34.7 centimeters (13.7 inches) per pixel (with 1 x 1 binning); objects on the order of 104 centimeters (40.9 inches) across are resolved.] North is up. This is a stereo pair with ESP_053406_2295. The University of Arizona, Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., Boulder, Colorado.
