Artist concept of Glaciers on Mars

A rippled dune front in Herschel Crater on Mars moved an average of about two meters (about two yards) between March 3, 2007 and December 1, 2010, as seen in these images from NASA's Mars Reconnais...

As the Sun peeks above the horizon at the Martian south polar icecap, powerful jets of carbon-dioxide (CO2) gas erupt through the icecap's topmost layer.

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...

Intra-Crater Structure in NW Hellas Basin, Mars

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 ...

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.

Lyot Crater, pictured here, is one of at least nine craters in the northern lowlands of Mars with exposures of hydrated minerals detected from orbit, according to a June 25, 2010, report.

How can you communicate with Mars spacecraft when the Sun is in the way? Learn more about 'solar conjunction' in this 60-second video.

This map shows the route driven by NASA's Curiosity Mars in its approach to and April 1, 2014, arrival at a waypoint called "the Kimberley," which rover team scientists chose in 2013 as the locatio...

This image shows a cross-section of a portion of the north polar ice cap of Mars, derived from data acquired by the Mars Reconnaissance Orbiter's Shallow Radar (SHARAD), one of six instruments on t...

This map indicates geological units in the region of Mars around a smaller area where NASA's Mars Exploration Rover Opportunity has driven from early 2004 through late 2010.

This image contrasts gullies and recurring warm-season slope flows appearing in the same crater, in the middle southern latitudes of Mars.

This animation flips back and forth between views taken in 2010 and 2014 of a Martian sand dune at the edge of Mount Sharp, documenting dune activity. The images are from the HiRISE camera on NASA'...

Dunes on Floor of Samara Valles, Mars

Several types of downhill flow features have been observed on Mars. This image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter is an exampl...

Stokes Crater, pictured here, is one of at least nine craters in the northern lowlands of Mars with exposures of hydrated minerals detected from orbit, according to a June 25, 2010, report.

This image covers a region of Mars near Nili Fossae that contains some of the best exposures of ancient bedrock on Mars.

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter snapped this series of false-color pictures of sand dunes in the north polar region of Mars

The movie you're watching here is a sequence of 3 HiRISE images that were taken of an object that might be the Beagle 2 lander in the Isidis Planitia.

The rock layers in this image were likely horizontal when the materials were first deposited, but are now tilted to high angles, approaching 90 degrees.

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...

A dramatic, fresh impact crater dominates this image taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter on Nov. 19, 2013.

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.

This is the first image of Mars taken by the Context Camera on NASA's Mars Reconnaissance Orbiter.

Part of the canyon floor and wall rock in southwestern Melas Chasma on Mars meanders in a pattern resembling a dragon.
