From HiWish: “Utopia Planitia is known to bear many thermal-contraction crack polygons. We suppose that their density & type depends on the geology of the substrate that bears them. With this image, we will investigate the presence of polygons on a dark-toned layered unit, very similar to other units further north that bear polygons themselves.”
