hellas planitia, mars, photographed by mars express, 23rd january 2014.
37 to 49°s, along 70°e longitude. central hellas planitia, some of the lowest terrain on mars (about 8km below datum). the bottom of the image shows the hellas chaos.
notice dark sand dunes in the 3rd and 5th images. the channel coming from left in the 1st image is enticingly sinuous, but i’d hesitate to speculate that it was eroded by water.
composite of visible light images, but the colour balance is not naturalistic.
