Artist's concept of future humans on Mars.

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 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).

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...

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

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...

Part of a multispectral THEMIS infrared image of Nili Patera caldera on Syrtis Major has been superimposed on a high-resolution THEMIS visual image.

Morning clouds fill Coprates Chasma on Mars in this Nov. 25, 2015, image from the THEMIS camera on NASA's Mars Odyssey. No orbiter systematically observed Mars in morning sunlight before 2015. The ...

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).

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

NASA's 2001 Mars Odyssey orbiter arrived at Mars on Oct. 24, 2001.

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

The floor of this crater in Terra Sirenum contains layered material. The layered sedimentary material on Mars is arguably the most interesting and compelling material on the planet. These layers mo...

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...

Fly Through Mariner Valley

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...

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

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

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...

At 11:02 a.m. EDT on April 7, 2001, crowds watch a Boeing Delta II rocket lift off from Cape Canaveral Air Force Station, Florida, carrying NASA's 2001 Mars Odyssey spacecraft into space on its sev...

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

Echus Chasma forms the boundary between the Tharsis volcanoes to the west and Lunae Planum to the east. This region is one of both tectonically fractured rocks (top of image) and volcanic flows (mi...

NASA's Mars Odyssey spacecraft passes above Mars' south pole in this artist's concept illustration. The spacecraft has been orbiting Mars since October 24, 2001.

This image superimposes Gamma-Ray Spectrometer data from NASA's Mars Odyssey orbiter onto topographic data from the laser altimeter on NASA's Mars Global Surveyor.

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...
