Annotated Version
A stereo view shows fractures called joints. They have a ridge-like shape,
standing out in positive relief as the surrounding bedrock is eroded away
faster than they are. This positive relief suggests that the rock along
the joints has been strengthened through chemical reactions with fluids
flowing through these joints.
The view appears three-dimensional when seen through red-green glasses. It
combines two images taken by the High Resolution Imaging Science
Experiment camera on NASA's Mars Reconnaissance Orbiter from slightly
different overhead positions. The constituent blue image is a portion of
image PSP_001641_1735 in the camera's catlog, taken Dec. 2, 2006. The red
image is part of PSP_002063_1735, taken Jan. 4, 2007.
The area covered in this image is about 5.8 kilometers (3.6 miles) wide,
located within Candor Chasma, approximately 60 kilometers (37 miles)
southeast of the area shown in PIA09190.
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.
