Artist concept of Glaciers on Mars

NASA's Mars Reconnaissance Orbiter observes many slopes in the middle latitudes of Mars showing icy flows or glaciers. The region shown here, in the south-facing slope of a crater, is unusual becau...

This scene is from early spring in the northern hemisphere of Mars. These dunes are covered with a layer of seasonal carbon dioxide ice (dry ice).

The total distance driven by NASA's Mars rover Curiosity passed the one-mile mark a few days before the first anniversary of the rover's landing on Mars.

This close-up image of a dust storm on Mars was acquired by the Mars Color Imager instrument on NASA's Mars Reconnaissance Orbiter on Nov. 7, 2007.

This area at the base of Mount Sharp on Mars includes a pale outcrop, called "Pahrump Hills," that NASA's Curiosity Mars rover investigated from September 2014 to March 2015, and the "Artist's Driv...

Image of Hesperia Planum from the HiRISE camera on Mars Reconnaissance Orbiter.

This image acquired on December 8, 2018 by NASAs Mars Reconnaissance Orbiter, shows erosion of the surface revealing several shades of light toned layers, likely sedimentary deposits.

This image shows a graben (a trough formed when the ground drops between two parallel faults) and a lava flow in the Tharsis volcanic province of Mars. North is up.

NASA's Mars Reconnaissance Orbiter has clocked more than a decade of service at the Red Planet and has yielded scientific discoveries and magnificent views of a distant world. These images taken by...

This image (top) taken by the Shallow Radar instrument on NASA's Mars Reconnaissance Orbiter reveals the layers of ice, sand and dust that make up the north polar ice cap on Mars

This map traces where NASA's Mars rover Curiosity drove between landing at a site subsequently named "Bradbury Landing," and the position reached during the mission's 130th Martian day, or sol, (De...

This graphic depicts the Mars Climate Sounder instrument on NASA's Mars Reconnaissance Orbiter measuring the temperature of a cross section of the Martian atmosphere as the orbiter passes above the...

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...

This image shows the floor of Ius Chasma

A rippled patch of sand in Becquerel Crater on Mars moved about two meters (about two yards) between November 24, 2006 and September 5, 2010, as observed in these images taken by NASA's Mars Reconn...

This chain of collapse pits located on the southeast flank of Alba Patera, a volcanic complex, probably formed when empty underground lava tubes collapsed.

In this Mars Reconnaissance Orbiter view of the Curiosity rover mission's waypoint called "the Kimberley," the red dot indicates the location of a sandstone target, "Windjana," selected for close-u...

This image lies in the middle of a candidate landing site in the Northeast part of Syrtis Major, a huge shield volcano, and near the Northwest rim of Isidis Planitia, a giant impact basin.

This anaglyph from HiRISE shows erosional features formed by seasonal frost near the south pole of Mars.

A large dust storm on Mars, nearly twice the size of the United States, covered the southern hemisphere of the Red Planet in early January 2022, leading to some of NASA’s explorers on the surface h...

This map shows the route on lower Mount Sharp that NASA's Curiosity followed between April 19, 2015, and Nov. 5, 2015. During this period the mission investigated silica-rich rock targets includin...

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...

NASA’s Mars Reconnaissance Orbiter captured this image of a meteoroid impact that was first detected by the agency’s InSight lander using its seismometer. This crater was formed on Aug. 30, 2021.
