Planum Boreum crater

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...

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

This false-color map shows the area within Gale Crater on Mars, where NASA's Curiosity rover landed on Aug. 5, 2012 PDT (Aug. 6, 2012 EDT).

The floor of this unnamed crater in Aonia Terra has been filled with multiple layers of material.

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...

When the Mars Exploration Rover, Opportunity, landed on Meridiani Planum in January 2004, it quickly found what it had been sent from Earth to find: evidence of liquid water in the Martian past.

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...

This image from NASA's Mars Odyssey shows ice-rich clouds over the summit of Arsia Mons.

A dust storm continues to envelop the Red Planet and Curiosity’s labs are back in action.

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

Wind shadow and real shadow combine to give a striking image of a comet.

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.

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

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

Researchers estimating the amount of carbon held in the ground at the largest known carbonate-containing deposit on Mars utilized data from three different NASA Mars orbiters.

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...

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.

Although it is 45 kilometers (28 miles) wide, countless layers of ice and dust have all but buried Udzha Crater.

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

Artist's concept of future humans on Mars.

Phobos and Deimos, the moons of Mars, are seen in this image from NASA's 2001 Mars Odyssey orbiter. The distance to Deimos from Odyssey during the observation was about 12,222 miles (19,670 kilomet...

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

This mosaic of day and night infrared THEMIS images shows landslides flowed over 100 kilometers (62 miles) across the floor of Melas Chasma.

No NASA Mars orbiter has been in a position to observe morning daylight on Mars since the twin Viking orbiters of the 1970s.

A false-color mosaic focuses on one junction in Noctis Labyrinthus where canyons meet to form a depression 4,000 meters (13,000 feet) deep.
