Artist concept of Glaciers on Mars

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

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...

This false-color animation simulates a fly-around look at one of the places on Mars where dark streaks advance down slopes during warm seasons, possibly involving liquid water or brine. This site i...

This graphic maps locations of the sites where NASA's Curiosity Mars rover collected its first 19 rock or soil samples for laboratory analysis inside the vehicle. It also presents images of the dri...

The Russell Crater dune field is covered seasonally by carbon dioxide frost. This image shows the dune field after the frost has sublimated, or evaporated directly from solid to gas. There are just...

NASA’s Perseverance Mars rover and Ingenuity helicopter were spotted on the surface of the Red Planet in this black-and-white image captured Feb. 26, 2022, by the HiRISE camera aboard NASA’s Mars R...

This image acquired on December 11, 2018 by NASAs Mars Reconnaissance Orbiter, shows a surface texture of interconnected ridges and troughs, referred to as brain terrain, found throughout the mid-l...

NASA's Curiosity Mars rover can be seen in this image taken from space on May 31, 2019, by the HiRISE camera aboard the Mars Reconnaissance Orbiter. In the image, Curiosity appears as a bluish speck.

This mosaic, taken with the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter, shows the planned route (in yellow) of NASA's Curiosity rover from "Pah...

The feature that appears bright blue at the center of this scene is NASA's Curiosity Mars rover on the northwestern flank of Mount Sharp, viewed by NASA's Mars Reconnaissance Orbiter. Curiosity is ...

This image acquired on January 25, 2019 by NASAs Mars Reconnaissance Orbiter, shows Ius Chasma, a major section of the western portion of the giant Valles Marineris trough.

This May 2015 image from the HiRISE camera on NASA's Mars Reconnaissance Orbiter shows a location on Mars associated with the best-selling novel and Hollywood movie, "The Martian." It is in a regio...

NASA's Curiosity rover and its parachute were spotted by NASA's Mars Reconnaissance Orbiter as Curiosity descended to the surface on Aug. 5 PDT (Aug. 6 EDT).

Collapsing Volcano; Edge of Olympus Mons

This sinuous raised ridge is thought to be an inverted stream channel.  These are formerly low-lying streambeds that became elevated because the original depression is filled with materials (such a...

Three images of the same location taken at different times on Mars show seasonal activity causing sand avalanches and ripple changes on a Martian dune.

Martian gullies as seen in the top image from HiRISE on NASA's Mars Reconnaissance Orbiter resemble gullies on Earth that are carved by liquid water. However, when they are observed with the additi...

This comparison of before-and-after images shows two spots that likely appeared in connection with the Oct. 19, 2016, Mars arrival of the European Space Agency's Schiaparelli test lander. The image...

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 Mars Climate Sounder, an instrument on NASA's Mars Reconnaissance Orbiter designed to monitor daily changes in the global atmosphere of Mars, made its first observations of Mars on March 24, 2006.

This image maps the traverse of NASA's Mars rover Curiosity from "Bradbury Landing" to "Yellowknife Bay," with an inset documenting a change in the ground's thermal properties with arrival at a dif...

This HiRISE image shows a valley filled with an assortment of linear ridges. These ridges are often referred to as transverse aeolian ridges, or TAR, and they take a variety of forms.

This map shows the route driven by NASA's Mars rover Curiosity through the 29th Martian day, or sol, of the rover's mission on Mars (Sept. 4, 2012).

Images like this from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter show portions of the Martian surface in unprecedented detail.
