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

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

This image of a crater in Acidalia Planitia was acquired March 8, 2003, during northern summer.

Ninth-grade, high-school students from Peoria, AZ analyze images of Mars.

Color coding in this map of a far-northern site on Mars indicates the change in nighttime ground-surface temperature between summer and fall. This site, like most of high-latitude Mars, has water i...

Mars is experiencing large regional dust storms over its northern hemisphere during the past week.

This image from NASA's 2001 Mars Odyssey spacecraft shows part of the caldera floor of Arsia Mons. Arsia Mons is the southernmost of the Tharsis volcanoes. It is 270 miles in diameter, almost 12 mi...

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

Getting to Mars is difficult enough -- staying there is even more challenging. Odyssey met up with Mars on October 24 02:26 UTC (October 23: 7:26 p.m. PDT/10:26 p.m.EDT).

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 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...

This image shows the context for orbital observations of exposed rocks that had been buried an estimated 5 kilometers (3 miles) deep on Mars.

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

This view combines information from two instruments on NASA's Mars Reconnaissance Orbiter to map color-coded composition over the shape of the ground in a small portion of the Nili Fossae plains re...

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...

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...

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

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

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 ...

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

This pair of maps indicates locations of confirmed sites of recurrent slope linea on Mars, with respect to elevation (upper map) and surface brightness, or albedo (lower map).

This unnamed channel drains part of Margaritifer Terra.

Valles Marineris, the "Grand Canyon of Mars," sprawls wide enough to reach from Los Angeles to nearly New York City, if it were located on Earth. The red outline box shows the location of a second,...

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