Artist's concept of future humans on Mars.

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

This mosaic of infrared images shows the abundance and location of hematite at Opportunity's landing site, Meridiani Planum. On Earth, hematite is a mineral that typically forms in water.

Bright blue marks a deposit of chloride (salt) minerals in the southern highlands of Mars in this false-color image, which highlights mineral composition differences.

This computer-generated view based on multiple orbital observations shows Mars' Gale crater as if seen from an aircraft north of the crater.

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

West of Valles Marineris lies a checkerboard named Noctis Labyrinthus, which formed when the Martian crust stretched and fractured.

This image combines two products from the first pointing at the Martian moon Phobos by the THEMIS camera on NASA's Mars Odyssey orbiter, on Sept. 29, 2017. Surface-temperature information from obse...

Sand dunes shaped like blue-black flames lie next to a central hill within an unnamed, 120-kilometer-wide (75-mile-wide) crater in eastern Arabia on Mars.

This is a Mars Odyssey visible color image of an unnamed crater in western Arcadia Planitia (near 39 degrees N, 179 degrees E). The crater shows a number of interesting internal and external featur...

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...

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...

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

Western flank of Elysium 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.

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.

This animation shows how NASA's Curiosity rover communicates with Earth via two of NASA's Mars orbiters, Mars Reconnaissance Orbiter (MRO) and Odyssey, and the European Space Agency's Mars Express....

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.

Hills abound in this portion of Mars located in the Vastitas Borealis region of the high northern plains. These hills are part of Scandia Colles. Note that some of the hills have aprons surrounding...

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

This artist's concept shows NASA's Mars orbiters lining up behind the Red Planet for their "duck and cover" maneuver to shield them fro comet dust that may result from the close flyby of comet Sidi...

Taken on April 24, 2019, this rainbow-colored image shows the Martian moon Phobos, as viewed by NASA's 2001 Mars Odyssey orbiter using its infrared camera, THEMIS. Each color represents a different...

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...
