Mars program Chief Engineer Robert Shotwell describes Mars Odyssey's unprecedented view of comet Siding Spring as the comet sweeps by the Red Planet on Oct. 19 and how it will maneuver to take images.

Valleys much younger than well-known ancient valley networks on Mars are evident near the informally named "Heart Lake" on Mars. This map presents color-coded topographical information overlaid ont...

This graphic shows the ongoing contributions of NASA’s rovers and orbiters during a Martian dust storm that began on May 30, 2018.

This mosaic of daytime infrared images of Gusev Crater, taken by the camera system on the Mars Odyssey spacecraft, has been draped over topography data obtained by Mars Global Surveyor.

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...

First THEMIS Image of Mars

THEMIS Support for Landing Site Selection

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

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

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

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

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

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...

When the Mars Exploration Rover, Opportunity, landed on Meridiani Planum in January 2004, it quickly found what it had been sent from Earth to find: evidence of liquid water in the Martian past.

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...

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.

How do you converse with a robot nearly one hundred million miles away? In this video, Odyssey team members describe communications with the 2001 Mars Odyssey spacecraft using the antennas of the D...

Re-analysis of 2002-2009 data from a hydrogen-finding instrument on NASA's Mars Odyssey orbiter increased the resolution of maps of hydrogen abundance. 

Colors in this image of the Martian moon Phobos indicate a range of surface temperatures detected by observing the moon on Sept. 29, 2017, with the Thermal Emission Imaging System (THEMIS) camera o...

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

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

On the southwest edge of the immense volcanic region of Tharsis, lava from its giant volcanoes flowed down to meet the old cratered landscape of Terra Sirenum.

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

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 ...
