Context image

This VIS image shows part of Hydraotes Chaos. Hydraotes Chaos measures about 300 kilometers (190 miles) wide by roughly 350 km (220 mi) north-south. The chaos lies in a valley leading northeast out of Ganges Chasma at the east end of Valles Marineris. Tiu Valles flows northward from Hydraotes Chaos to empty into Chryse Planitia. In planetary nomenclature, the descriptor term chaos means "distinctive area of broken terrain". The general morphology of chaos is steep-sided mesas in close proximity. With time and erosion the valleys widen and the mesas grow smaller. The initial breakup of the land can be due to tectonic forces, but on Mars it is thought that the release of melted, subsurface ice created the terrain. Large channels, like Tiu Valles, usually originate from regions of chaos.

NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Science Mission Directorate, Washington, D.C. The Thermal Emission Imaging System (THEMIS) was developed by Arizona State University, Tempe, in collaboration with Raytheon Santa Barbara Remote Sensing. The THEMIS investigation is led by Dr. Philip Christensen at Arizona State University. Lockheed Martin Astronautics, Denver, is the prime contractor for the Odyssey project, and developed and built the orbiter. Mission operations are conducted jointly from Lockheed Martin and from JPL, a division of the California Institute of Technology in Pasadena.
