Dunes in Aonia Terra

If a meteorite breaks in two shortly before hitting the ground, the typical bowl shape of a single impact crater becomes doubled.

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.

This mosaic image of Valles Marineris - colored to resemble the martian surface - comes from the Thermal Emission Imaging System (THEMIS), a visible-light and infrared-sensing camera on NASA's Mars...

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

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 artist's animation depicts how NASA's Curiosity rover will communicate with Earth during landing. As the rover descends to Mars, it will send out basic radio-frequency tones that go directly to...

NASA's Mars Odyssey spacecraft passes above a portion of the planet that is rotating into the sunlight in this artist's concept illustration. The spacecraft has been orbiting Mars since October ...

This image captured by NASA's 2001 Mars Odyssey spacecraft shows 'streamers' of clouds created by katabatic winds at the north polar cap.

Gale Crater, home to NASA's Curiosity Mars rover, shows a new face in this image made using data from the THEMIS camera on NASA's Mars Odyssey orbiter.

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

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

Artist’s concept of Comet Siding Spring approaching Mars, shown with NASA’s orbiters preparing to make science observations of this unique encounter.

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).

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...

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

This movie shows three views of the Martian moon Phobos as viewed in visible light by NASA's 2001 Mars Odyssey orbiter. The apparent motion is due to movement by Odyssey's infrared camera, Thermal ...

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

A "Grand Canyon of Mars" slices across the Red Planet near its equator.

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...

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 map of Mars indicates locations of new craters that have excavated ice (blue) and those that have not (red). The underlying map is based on the brightness, or albedo, of the Martian surface.

This image from NASA's Mars Odyssey shows a crater from a double impact - two meteors hitting simultaneously. The two meteors would have started as a single object and, at some point prior to impac...

A lunar eclipse, a solar eclipse and Mars has a close encounter with a comet.

At the time this video was released, the Odyssey team had successfully completed the third trajectory correction maneuver to adjust the spacecraft's flightpath toward its final aimpoint for entry i...

This THEMIS visible image shows a close-up view of the ridged plains in Hesperia Planum. This region is the classic locality for martian surfaces that formed in the "middle ages" of martian history.
