Artist's concept of future humans on Mars.

Geological faulting has opened cracks in the Cerberus region that slice through flat plains and mesas alike.

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

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...

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...

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

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 is advancing the Journey to Mars by starting the conversation about where humans may one day land on the Red Planet.

Women working in science, technology, engineering and mathematics at NASA's Jet Propulsion Laboratory pose for a photo in mission control in honor of Women in Science Day.

This movie shows three views of the Martian moon Phobos as viewed in visible light by NASA's 2001 Mars Odyssey orbiter. The apparent motion is due to movement by Odyssey's infrared camera, Thermal ...

This image of Phobos is one product of the first pointing at that Martian moon by the THEMIS camera on NASA's Mars Odyssey orbiter.  The Sept. 29, 2017, observation also provided information about ...

This map shows unprecedented detail of local variations in Mars' gravitational pull on orbiters. The gravitational mapping has been applied to map variations in the thickness of the planet's crust ...

These three views of the Martian moon Phobos were taken by NASA's 2001 Mars Odyssey orbiter using its infrared camera, THEMIS. Each color represents a different temperature range.

First THEMIS Image of Mars

This movie shows the Martian moon Phobos as viewed in visible light by NASA's 2001 Mars Odyssey orbiter on April 24, 2019. The apparent motion is due to movement by Odyssey's infrared camera, Therm...

A large sandsheet with surface dune forms is shown in today's image of Aonia Terra.

Six views of the Martian moon Phobos captured by NASA's Odyssey orbiter as of March 2020. The orbiter's THEMIS camera is used to measure temperature variations that suggest what kind of material th...

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 movie begins with an animation (artist's rendering) of NASA's Mars Reconnaissance Orbiter spacecraft above Mars. The scene zooms into an "X-ray" view of the spacecraft, revealing the High Reso...

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,...
