Elysium Planitia, Mars -- Fractured Mounds in Stereo

This stereo view shows fractured mounds on the southern edge of Elysium Planitia on Mars.

Periodic Layering in Martian Sedimentary Rocks, Oblique View

This oblique view of periodic layering in Martian sedimentary layers was derived from three-dimensional modeling based on a stereo pair of images taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.

Periodic Layering in Martian Sedimentary Rocks

This image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter shows sedimentary-rock layering in which a series of layers are all approximately the same thickness.

Periodic Layering in Becquerel Crater, Mars

Rhythmic bedding in sedimentary bedrock within Becquerel crater on Mars is suggested by the patterns in this image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.
