Artist concept of Glaciers on Mars

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.

A region known as "Cape York" on the western rim of Endeavour Crater, where NASA's Mars Exploration Rover Opportunity worked for 20 months, is highlighted in these images.

This image from NASA's Mars Reconnaissance Orbiter shows blocks of layered terrain within the Olympus Mons aureole. The aureole is a giant apron of chaotic material around the volcano.

These dark streaks, also known as “slope streaks,” resulted from dust avalanches on Mars. The HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter captured them on Dec. 26, 2017.

Dry ice causes "Swiss Cheese" terrain on Mars.

This kickoff of a new Mars video series covers Opportunity's 14th anniversary on the Red Planet, Curiosity's spectacular panorama and ice deposits spotted by an orbiter.

These dunes may be active today, but we haven't yet observed them at significantly different times to measure the movement.

Back-and-forth blinking of this two-image animation shows movement of a sand dune on Mars. The images are part of a study published by Nature on May 9, 2012, reporting movement of Martian sand dune...

This animation shows how NASA's Curiosity rover communicates with Earth via two of NASA's Mars orbiters, Mars Reconnaissance Orbiter (MRO) and Odyssey, and the European Space Agency's Mars Express....

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.

Details such as the shadow of the mast on NASA's Mars rover Curiosity appear in an image taken Aug. 17, 2012, by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconn...

HiRISE captured this image of an eroded mesa made famous by its similarity to a human face in a Viking Orbiter image with much lower spatial resolution and a different lighting geometry.

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...

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...

NASA's Mars Reconnaissance Orbiter, nearing the 10th anniversary of its arrival at Mars, used its High Resolution Imaging Science Experiment (HiRISE) camera to obtain this view of an area with unus...

This image from NASA's Mars Reconnaissance Orbiter shows Aram Chaos, an ancient impact crater that lies within in the Southern Highlands of Mars. Uplifted blocks are composed largely of the iron-ox...

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

This 3D, or stereo anaglyph, view shows the upcoming science destination for NASA's Mars rover Curiosity, a region dubbed "Glenelg," where three different types of material seen from orbit come tog...

The north polar layered deposits, and the bright ice cap that covers them, are very young (by geologic standards) features.

This color-enhanced view shows the terrain around the rover's landing site within Gale Crater on Mars.

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

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...

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.
