Meridiani Planum

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.

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...

Artist rendering of commercial Mars satellites providing communications back to Earth.

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

This view of an area about 140 kilometers (about 90 miles) wide in the Meridiani Planum region of Mars shows the region around NASA's Mars Exploration Rover Opportunity.

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

Chasma Boreale is a long, flat-floored valley that cuts deep into Mars' north polar icecap

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

Western flank of Elysium Mons.

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...

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 ...

A vast dune field lies near the northern polar cap of Mars. Seen here in summer, the dunes have partially buried an impact crater about 1,000 meters (3,300 feet) wide.

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

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 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).

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

The annotated area of Mars in this illustration holds near-surface water ice that would be easily accessible for astronauts to dig up. The water ice was identified as part of a map using data from ...

Planum Boreum crater

A group of small, unnamed craters in the martian southern hemisphere is the first site captured by a group of middle school students who are operating the camera system onboard NASA's Mars Odyssey ...

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

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).

Stages in the seasonal disappearance of surface ice from the ground around the Phoenix Mars Lander are visible in these images taken on Feb. 8, 2010, (left) and Feb. 25, 2010, during springtime on ...

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...
