Possible Water Flows on Mars

The Mars Reconnaissance Orbiter’s Context Camera, which captured the 110,000 images that make up the interactive global mosaic, is especially useful for spotting impact craters like those seen here.

This image from NASA's Mars Reconnaissance Orbiter shows a hill with a central crater. Such features have been interpreted as both mud volcanoes (really a sedimentary structure) and as actual volca...

This image from NASA’s Mars Reconnaissance Orbiter shows spider-like formations at the Martian South Pole. They form when heating from the springtime Sun causes carbon dioxide beneath the surface t...

This color view of the parachute and back shell that helped deliver NASA's Curiosity rover to the surface of the Red Planet was taken by the High-Resolution Imaging Science Experiment (HiRISE) came...

This image acquired on October 1, 2020 by NASAs Mars Reconnaissance Orbiter, shows several craters in Arabia Terra filled with layered rock.

The Global CTX Mosaic of Mars allows scientists and the public to explore the planet like never before.

Artist's concept of Mars Reconnaissance Orbiter

This map shows unprecedented detail of local variations in Mars' gravitational pull on orbiters. The gravitational mapping has been applied to map variations in the thickness of the planet's crust ...

This is a close-up of the area in the vicinity of the Pathfinder landing site. Major features are named. The white box outlines the area of the image, where hardware is seen.

Gullies and Flow Features along Crater Wall in Promethei Terra

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter acquired this image of the Opportunity rover on the southwest rim of "Santa Maria" crater on New...

By analyzing radar images like the one at top of this montage, scientists discovered evidence for a past ice age in the northern polar ice cap of Mars.

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

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

This map shows five locations where fresh impact cratering has excavated water ice from just beneath the surface of Mars (sites 1 through 5) and the Viking Lander 2 landing site (VL2), in the conte...

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.

Wrinkle Ridge, Solis Planum

This dune field in Aonia Terra shows sand dunes with a variety of morphologies. These complex shapes often indicate that the dominating winds change direction, either over time or from one locatio...

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...

Candor Chasma is one of the major canyons within Valles Marineris. The floor of this canyon consist of many layers of light-toned sediments that have been folded and faulted, giving them the wavy a...

This view shows the ground covered in the first image of Mars taken by the High Resolution Imaging Science Experiment camera (HiRISE) on NASA's Mars Reconnaissance Orbiter

This image acquired on December 26, 2018 by NASAs Mars Reconnaissance Orbiter, shows the hills that resulted from uplifted rocks due to an impact that formed the 230-kilometer diameter Galle Crater.

The Mars Color Imager test view looks northward and includes the large Argyre Basin in Mars' southern hemisphere.

This view combines information from two instruments on NASA's Mars Reconnaissance Orbiter to map color-coded composition over the shape of the ground in a small portion of the Nili Fossae plains re...
