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.

A Gem of a Find

NASA's Mars Reconnaissance Orbiter has revealed Martian rocks containing a hydrated mineral similar to opal.

Unusual Mound in North Polar Layered Deposits

A striking image from NASA's Mars Reconnaissance Orbiter shows a mound within the area of a trough cutting into Mars' north polar layered deposits.

Deformation Bands in Martian Bedrock

Dense clusters of crack-like structures called deformation bands form the linear ridges prominent in this image from NASA's Mars Reconnaissance Orbiter.

Growing Library of Mars Spectrometer Images

This image in enhanced color from visible-light wavelengths shows light-toned rugged highland material in an area near the Martian equator.

Ius Chasma's Floor

This image spans the floor of Ius Chasma's southern trench.

Inverted Channels North of Valles Marineris

Features believed to indicate where channels used to flow on Mars can be seen in this image taken by the High Resolution Imaging Science Experiment (HiRISE) camera in NASA's Mars Reconnaissance Orbiter.

Clay Minerals in Mawrth Vallis Region of Mars

This map showing the location of some clay minerals in of a portion of the Mawrth Vallis region of Mars covers an area about 10 kilometers (6.2 mile) wide.

Water-Rich Terrain

This three-dimensional image of a trough in the Nili Fossae region of Mars shows a type of minerals called phyllosilicates concentrated on the slopes of mesas and along canyon walls.

Organic Cemetery

A color-enhanced image of the delta in Jezero Crater, which once held a lake.

What Lies Below a Martian Ice Cap

This image shows a radar view (top) and topographical view (bottom) of the north polar ice cap on Mars.

How Thick is the North Polar Ice Cap on Mars?

This map shows the thickness of the north polar layered deposits on Mars as measured by the Shallow Radar instrument on NASA's Mars Reconnaissance Orbiter.

Peeling Back Layers of a Martian Polar Ice Cap

This artist's animation illustrates how NASA's Mars Reconnaissance Orbiter used radar to map the insides of the north polar ice cap on Mars.

Phoenix Landing Area Viewed by Mars Color Imager

NASA's Mars Reconnaissance Orbiter captured this view of a large region of northern Mars that includes the Phoenix mission landing target area in the lower right quadrant.

Context Camera Spots Dust Devils at Phoenix Landing Site

In preparation for the landing of the Mars Phoenix Lander, NASA's Mars Reconnaissance Orbiter has been monitoring weather in the region around the landing site.

Context Camera View in Phoenix Landing Region in Martian Arctic
