This mosaic from the Mast Camera on NASA's Curiosity rover shows
a close-up view looking toward the "Glenelg" area, where three
different terrain types come together. All three types are
observed from orbit with the High-Resolution Imaging Science
Experiment (HiRISE) camera on NASA's Mars Reconnaissance
Orbiter. By driving there, Curiosity will be able to explore
them. One of these terrain types is light-toned with well-
developed layering, which likely records the deposition of
sedimentary materials. There are also black bands that run
through the area and might constitute additional layers that
alternate with the light-toned layer(s). The black bands are not
easily seen from orbit and are on the order of about 3.3-feet
(1-meter) thick. Both of these layer types are important science
targets. This mosaic is composed of images taken with the
Mastcam 100-millimeter camera. Image Credit: NASA/JPL-
