Terrain in Vastitas Borealis Region

The Mars Reconnaissance Orbiter has seen many places on the planet. One of the most interesting is one of the great canyon systems on Mars.

The new global mosaic, shown in a detail example at left, is stitched together from images taken by MRO’s Context Camera, which captures the Martian surface in long strips. The process is revealed ...

This is a diagram that shows the launch phases for the Mars Reconnaissance Orbiter.

A digital terrain model generated from a stereo pair of images provides this synthesized, oblique view of a portion of the wall terraces of Mojave Crater in the Xanthe Terra region of Mars.

This image shows layered blocks tilted at high angles, diverse color and textures and dark dunes. Some of the bedrock may have originated at great depths, uplifted first by Becquerel Crater and lat...

In February 2015, NASA's Mars Exploration Rover Opportunity is approaching a cumulative driving distance on Mars equal to the length of a marathon race. This map shows the rover's position relative...

NASA’s Mars Reconnaissance Orbiter used its Context Camera to capture this image of Bosporos Planum, a location on Mars. The white specks are salt deposits found within a dry channel. The largest i...

This series of images shows warm-season features that might be evidence of salty liquid water active on Mars today.

By analyzing radar images like the one at top of this montage, scientists discovered evidence for a past ice age in the northern polar ice cap of Mars.

In Aureum Chaos, the OMEGA experiment on Mars Express indicated the presence of phyllosilicates (clay minerals) which have been detected in a variety of bright outcrops and scarps. The subimage sho...

This animation blinks between two images of NASA's Mars Phoenix Lander hardware around the mission's 2008 landing site on far-northern Mars.  By late 2017, dust obscures much of what was visible tw...

This image of Victoria Crater in the Meridiani Planum region of Mars was taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter at more of a s...

NASA's Opportunity Mars rover, working on Mars since January 2004, passed marathon distance in total driving on March 24, 2015. This map shows the rover's entire traverse from landing to that point.

This image shows blocks of bright, layered rock embedded in darker material that are thought to have been deposited by a giant flood that occurred when Uzboi Valles breached the rim of Holden Crater.

This series of images shows carbon dioxide ice sublimating (going directly from a solid to a gas) inside a pit at Mars' south pole. Each frame of the animation was taken by the HiRISE camera on NAS...

These images from orbit show an area near Mars' south pole where coalescing or elongated pits are interpreted as signs that an underlying deposit of frozen carbon dioxide, or "dry ice," has been sh...

A view from NASA's Mars Reconnaissance Orbiter on April 8, 2015, catches sight of NASA's Curiosity Mars rover passing through a valley called "Artist's Drive" on the lower slope of Mount Sharp.

This Southern autumn image captures a view of frosty dunes. The sunlight is shining on the dunes from the upper right.

Mesas in Aureum Chaos

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter caught this view of NASA's Mars Exploration Rover Opportunity on Feb. 14, 2014.

Impact cratering and erosion combine to reveal the composition of the Martian underground by exposing materials from the subsurface.

Sand dunes are among the most widespread aeolian features present on Mars. Their spatial distribution and morphology are sensitive to subtle shifts in wind circulation patterns and wind strengths. ...

This crater is named for G. Edward Danielson, Jr. who was instrumental in the development of a series of Mars cameras, from Mariner 4 launched in 1964 to the Mars Global Surveyor launched in 1996.

These long, smooth features are sand ridges shaped by the constant martian wind. They run perpendicular, or at right angles to, the direction of the wind and often found in channels and crater inte...
