On the northern edge of Valles Marineris lies Ophir Chasma, a 317 kilometer long network of valleys and broken ground framed by high-walled cliffs and layered deposits.
And, just in time for India's Independence Day, the India Space Research Organization (ISRO) Mangalyaan probe has captured the canyon in stunning relief.
Mangalyaan, which means "Mars-craft in Sanskrit, is a great success story. Although the initial images it returned were blurry and disappointing, the orbiter switched to its color camera and returned some truly remarkable pictures, including one that has since been transformed into a 3D construct of the surface. This is perhaps the most realistic representation of the Martian surface we have ever seen.
