Though the coloring is artificially enhanced, the unique features of this formation, located in two distinct craters, are anything but ordinary. NASA scientists recently released two detailed images taken by the MRO’s HiRISE camera, showing separate dune fields inside Lyot Crater and Gamboa Crater. These images don’t just offer stunning visuals; they open a rare window into the complex interactions between Martian winds and surface materials. The unusually shaped and...
