Mars
Express took several snapshots of Candor Chasma, a valley in the northern part
of Valles Marineris, now redone by German researchers as a 3-D model.
The Mars
spacecraft needs just one pass with its High Resolution Stereo Camera to take
images of a Martian landmark on approach, directly overhead, and receding into
the distance. Scientists can then use those images to create Digital Terrain
Models that allow scientists to view the Martian landscape from multiple
angles. The models also allow scientists to easily gauge the depth of canyons
or craters, which leads to more effective use of other instruments such as
radar.
The Candor Chasma
lies within the great Valles Marineris system of canyons that may have been
partially carved by water.
