Planum Australe Region

This view of layered rocks on the floor of McLaughlin Crater shows sedimentary rocks that contain spectroscopic evidence for minerals formed through interaction with water.

This map shows the frequency of carbon dioxide frost's presence at sunrise on Mars, as a percentage of days year-round. Carbon dioxide ice more often covers the ground at night in some mid-latitude...

The bright landing platform left behind by NASA's Mars Exploration Rover Opportunity in 2004 is visible inside Eagle Crater, where "Opportunity Lander" is indicated in this annotated, April 8, 2...

Curiosity performs the first investigation of active sand dunes on another planet. Studying the Bagnold Dunes on Mars will help scientists understand the physics of Martian dunes and how they move.

Researchers estimating the amount of carbon held in the ground at the largest known carbonate-containing deposit on Mars utilized data from three different NASA Mars orbiters.

This view of layered rocks on the floor of McLaughlin Crater shows sedimentary rocks that contain spectroscopic evidence for minerals formed through interaction with water.

Drainage Near Crater in Terra Sabaea.

Two types of wind-blown sedimentary deposits are pictured in this scene of the floor of Ius Chasma in the Valles Marineris.

This view of a portion of the Eridania region of Mars shows blocks of deep-basin deposits that have been surrounded and partially buried by younger volcanic deposits. The image was taken by the Con...

'Marsshine' on Shadowed Part of Phobos

This image, acquired by NASAs Mars Reconnaissance Orbiter, shows a new impact crater that has appeared on the surface of Mars, formed at most between September 2016 and February 2019.

This terrain is covered by pits and scallops (pits open on one side), perhaps due to collapse after sublimation of subsurface ice.

This graphic depicts the relative shapes and distances from Mars for five active orbiter missions plus the planet's two natural satellites. It illustrates the potential for intersections of the spa...

Five decades of successful NASA missions to the Red Planet, 1965-2015.

This map shows where NASA's Mars rover Curiosity has driven since landing at a site subsequently named "Bradbury Landing," and traveling to an overlook position near beside "Point Lake," in drives ...

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 artist's animation shows how NASA's Curiosity rover will communicate with Earth via two of NASA's Mars orbiters, Mars Reconnaissance Orbiter and Odyssey. As the rover descends to the surface o...

The Eridania basin of southern Mars is believed to have held a sea about 3.7 billion years ago, with seafloor deposits likely resulting from underwater hydrothermal activity. This graphic shows est...

As on the Earth, many processes can move material down a Martian slope. This graphic compares seven different types of features observed on Mars that appear to result from material flowing or slidi...

Common to the northern plains of Mars are rock and boulder strewn landscapes otherwise devoid of major features except a few impact craters. This image in the Cydnus Rupes region of northern Utopia...

A dust storm continues to envelop the Red Planet and Curiosity’s labs are back in action.

The black speck circled in the lower left corner of this image is a cluster of recently formed craters spotted on Mars using a new machine-learning algorithm. This image was taken by the Context Ca...

NASA's InSight spacecraft and its recently deployed Wind and Thermal Shield were imaged on Feb. 4 by the HiRISE camera aboard NASA's Mars Reconnaissance Orbiter.

This image of Santa Maria Crater was taken by the High Resolution Imaging Science Experiment (HiRISE) camera on Mars Reconnaissance Orbiter.

The High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA's Mars Reconnaissance Orbiter captured these sand ripples and the large dune (at center) on Feb. 9, 2009. Color has been a...
