The THEMIS Image of the Day will be exploring the nomenclature of Mars for the next three weeks.
Hebes Chasma is part of a smaller chasma system located north of the main Valles Marineris chasma system. In this VIS image both walls of the canyon are visible. Note the layering near the top of the canyon walls, and the erosion of material.
Nomenclature Fact of the Day: Major bright features on Titan will be named for sacred or enchanted places from legends, myths, stories, and poems from cultures around the world. Major dark features will be named for legendary or mythical primordial seas or enchanted waters. Other features will be named for deities of happiness, peace, and harmony.
[Source: ASU THEMIS Science Team]Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion. Fully calibrated and geometrically projected images will be released through the Planetary Data System in accordance with Project policies at a later time.
NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, 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.
