Meridiani Planum

This graphic depicts the relative shapes and distances from Mars for five active orbiter missions plus the planet's two natural satellites. It illustrates the potential for intersections of the spa...

This graphic shows the ongoing contributions of NASA’s rovers and orbiters during a Martian dust storm that began on May 30, 2018.

This image from NASAs Mars Odyssey shows lava flows from Alba Mons, and a tectonic graben called Cyane Fossae.

On the southwest edge of the immense volcanic region of Tharsis, lava from its giant volcanoes flowed down to meet the old cratered landscape of Terra Sirenum.

As fractures opened near the summit of Tyrrhena Patera, the ground collapsed to make pits and chains of pits aligned with the fractures. The large pit seen here is about 400 m (1,300 ft) deep.

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.

This THEMIS image of rounded hills and ridges in Arcadia Planitia shows a very intriguing geomorphic feature that may be attributed to the presence of an icy-rock mixture of material. Smooth aprons...

This image shows a 90-mile-wide portion of the giant Valles Marineris canyon system. Landslide debris and gullies in the canyon walls on Mars can be seen at 100 meters (330 feet) per pixel.

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 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...

These three views of the Martian moon Phobos were taken by NASA's 2001 Mars Odyssey orbiter using its infrared camera, THEMIS. Each color represents a different temperature range.

This unnamed channel drains part of Margaritifer Terra.

Women working in science, technology, engineering and mathematics at NASA's Jet Propulsion Laboratory pose for a photo in mission control in honor of Women in Science Day.

Sixteen seventh-graders at Evergreen Middle School in Cottonwood, Calif., found the Martian pit feature at the center of the superimposed red square in this image while participating in a program t...

Snow falls and ice and frost form on Mars, too. NASA's spacecraft on and orbiting the Red Planet reveal the similarities to and differences from how we experience winter on Earth.  

The Thermal Emission Imaging System (THEMIS) camera on NASA's Mars Odyssey spacecraft has completed an unprecedented full decade of observing Mars from orbit.

First THEMIS Image of Mars

The channels in this VIS image are part of Tyrrhena Fossae on the northern flank of Tyrrhenus Mons.

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

A vast dune field lies near the northern polar cap of Mars. Seen here in summer, the dunes have partially buried an impact crater about 1,000 meters (3,300 feet) wide.

This lunar-like scene occurs along the southeastern rim of the Isidis Planitia basin. The Isidis basin is an ancient impact crater some 1200 km across that is found along the boundary separating th...

This image is near the southern edge of a low, broad volcanic feature called Syrtis Major.

A new map of Mars' gravity made with three NASA spacecraft is the most detailed to date, providing a revealing glimpse into the hidden interior of the Red Planet. Satellites always orbit a planet's...
