Justin Cowart is a geologist and amateur astronomer living in Carbondale, IL. Justin has had a lifelong interest in exploring space, and one of the most fun ways to satisfy that curiosity has been looking at the images returned by space missions. His interests lie in reprocessing old data (which looks surprisingly good when it's run through modern computers!) and finding aesthetically-pleasing images that may not have gotten noticed otherwise. He can be found on Twitter as @jccwrt, and on Flickr.
Mars Express view of southern Noachis Terra on December 19, 2015. This image was made from a two color (blue/green) observation of hazes in the atmosphere. This image is largely centered on Solis Planum and the Thaumasia Plateau, a large lava plain. These regions are among the highest terrain on Mars outside of the Tharsis volcanoes. A networked cluster of fissures known as Noctis Labyrinthus is visible along the left edge of the image. These fissures form the western end of the Valles Marineris canyon system and were formed by the immense weight of the Tharsis volcanoes cracking the surface open.
