This enhanced-color view of the eastern rim and floor of "Victoria Crater" in Mars' Meridiani Planum region comes from the High Resolution Imaging Science Experiment camera in NASA's Mars Reconnaissance Orbiter.
It shows ridges that may be fractures surrounded by chemically cemented sedimentary bedrock. The ridges are therefore potentially fruitful targets for analysis by NASA's Mars Exploration Rover Opportunity, which is investigating the rim of this crater.
Illumination is from the upper left.
The image is a detail from a image TRA_000873_1780 in the camera's catalog [PIA08813], taken on Oct. 3, 2006.
NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Reconnaissance Orbiter for NASA's Science Mission Directorate, Washington. Lockheed Martin Space Systems, Denver, is the prime contractor for the project and built the spacecraft. The High Resolution Imaging Science Experiment is operated by the University of Arizona, Tucson, and the instrument was built by Ball Aerospace and Technology Corp., Boulder, Colo.
