Artist concept of Mars Reconnaissance Orbiter

This map shows the footprints of images taken by the HiRISE camera on NASA's Mars Reconnaissance Orbiter as part of advance analysis of the area where NASA's InSight mission will land in 2018. The ...

Polygons are of great interest because they often indicate the presence of shallow ice or of desiccation such as in a mud flat. However, nature sometimes seems too clever for us.

Wind is one of the most active forces shaping Mars’ surface in today’s climate. Wind-carved features such as these, called “yardangs,” are common on the Red Planet.

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

Northern Hemisphere Gullies on West-Facing Crater Slope, Mars

Eberswalde Crater contains layered rocks about 100-meters thick exposed in a a well-preserved delta.

Is frozen carbon dioxide a key to features in some Martian gullies? To find out, scientists grabbed a bag of dry ice and took a road trip.

This HiRISE image shows diverse layers in a region near Mawrth Vallis, a channel that was probably carved by water in Mars' ancient past. The color subimage shows details of layers exposed in a cra...

Recent small craters discovered by the High Resolution Imaging Science Experiment camera on NASA's Mars Reconnaissance Orbiter expose buried ice in the middle latitudes of Mars.

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...

The Global CTX Mosaic of Mars allows scientists and the public to explore the planet like never before. 

This graphic shows the ongoing contributions of NASA’s rovers and orbiters during a Martian dust storm that began on May 30, 2018.

Syrtis Major Region

This is a small volcano superimposed on the flanks of a larger one of the Cerberus Tholi.

This picture was taken during the Martian summer with only small patches of ice remaining at the surface; they show up as bright, somewhat blue, spots on slopes that provide some shading from the Sun.

Follow along on a tour of the landing scene of NASA's Curiosity rover in this video made up of images from two NASA orbiters. The movie begins with a global image from NASA's Mars Global Surveyor, ...

NASA's Curiosity Mars rover and tracks from its driving are visible in this view from orbit, acquired on April 11, 2014, by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's ...

Intra-Crater Structure in NW Hellas Basin, Mars

This image taken by NASA’s Mars Reconnaissance Orbiter shows ice sheets at Mars’ south pole. The spacecraft detected clays nearby this ice; scientists have proposed such clays are the source of rad...

This sequence of images shows a blast zone where the sky crane from NASA's Curiosity rover mission hit the ground after setting the rover down in August 2012, and how that dark scar's appearance ch...

This image acquired on January 13, 2019 by NASAs Mars Reconnaissance Orbiter, shows a cluster of dust devil tracks on the flat ground below the south polar layered deposits, but none on the layers ...

This Oct. 25, 2016, image from the HiRISE camera on NASA's Mars Reconnaissance Orbiter shows the area where the Europe's Schiaparelli test lander struck Mars, with magnified insets of three sites w...

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.

Wrinkle Ridge in Solis Planum

These collapse pits probably formed when lava erupted from the side of Arsia Mons, draining underground magma reservoirs. The resulting voids collapse due to the weight of the solid lava above them...
