Planum Boreum crater

In Ares Vallis, teardrop mesas extend like pennants behind impact craters, where the raised rocky rims diverted the floods and protected the ground from erosion.

Valleys much younger than well-known ancient valley networks on Mars are evident near the informally named "Heart Lake" on Mars. This map presents color-coded topographical information overlaid ont...

This region of Terra Sabaea contains areas with high densities of small craters.

This artist's animation shows how orbiters over Mars will monitor the landing of NASA's Curiosity rover. (No audio)

Olympica Fossae is a complex channel located on the volcanic plains between Alba Mons and Olympus Mons. The sinuosity of the large channel in the middle of this image from NASA's 2001 Mars Odyssey ...

The annotated area of Mars in this illustration holds near-surface water ice that would be easily accessible for astronauts to dig up. The water ice was identified as part of a map using data from ...

This image shows two small tributaries, just east of where they join Shalbatana Vallis.

This image from NASA's 2001 Mars Odyssey spacecraft shows part of the margin of the north polar cap and the surrounding plains. The layering of the ice is easily visible due to the dust that is dep...

NASA's Phoenix Mars Lander, its backshell and its heatshield are visible within this enhanced-color image of the Phoenix landing site taken on Jan. 6, 2010 by the High Resolution Imaging Science Ex...

This color-coded map indicates the depth to icy layers at a site in southern Mars. The dense, icy layer retains heat better than the looser soil above it, so where the icy layer is closer to the su...

Just as on Earth, volcanism and tectonism are found together on Mars. Here is an example: the ridges and fractures of Claritas Fossae are affecting or perhaps hosting the volcanic flows of Solis Pl...

NASA’s 2001 Mars Odyssey orbiter is depicted in this illustration.

Seasons change even on Mars and NASA's fleet of explorers are helping scientists learn more about the effects on the Red Planet.

Fans and ribbons of dark sand dunes creep across the floor of Bunge Crater in response to winds blowing from the direction at the top of the picture. The frame is about 14 kilometers (9 miles) wide.

The dunes and dust devil tracks in this VIS image are located on the plains of Planum Chronium.

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...

NASA is advancing the Journey to Mars by starting the conversation about where humans may one day land on the Red Planet.

A sea of dark dunes, sculpted by the wind into long lines, surrounds the northern polar cap covering an area as big as Texas.

The dune field in this polar region crater looks like a stubby arrow pointing the way west. This unnamed crater is located in Planum Chronium.

Marte Vallis, located in Amazonis Planitia, is broad and shallow. The streamlined islands at the top and bottom of the image illustrate this.

Artist's concept of future humans on Mars.

A small basin (center foreground) lies below the southern rim of Melas Chasma, part of Valles Marineris.

Bacolor Crater is a magnificent impact feature about 20 kilometers (12 miles) wide.

The Odyssey spacecraft was launched toward Mars on April 7, 2001 from Cape Canaveral, Florida. In this four-part video series, Odyssey navigation team members explain the daily challenges of steeri...
