Mars Odyssey THEMIS Image: Lycus Sulci 06-06-2003
 Image Context:  Context image credit: NASA/Mars Orbiter Laser Altimeter (MOLA) Team [ Find on map: Javascript version ] [ Find on map: CGI version ] The remarkably rugged terrain that is part of a massive lobe of material extending over 700 km from the basal scarp of Olympus Mons is called sulci, which means furrows or grooves. This Latin word especially applies to the furrows on the surface of the brain, a definition that is visually fitting in the case of this image. The furrows are roughly a half to one km deep. Note the abundance of dark-toned slope streaks, which demonstrates that this is a region with significant dust accumulation. [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.
