This image from NASA's 2001 Mars Odyssey spacecraft shows part of the margin of the north polar cap and the surrounding plains. The layering of the ice is easily visible due to the dust that is dep...

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

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.

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

Odyssey launched on Boeing's Delta II 7925 that uses nine strap-on solid rocket motors.

This false color image shows a region with craters of different ages located at the margin of Acidalia Planitia. This image was collected during the Northern Spring season.

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...

These are two views of the same observation of the Martian moon Phobos taken in both infrared and visible light by NASA's 2001 Mars Odyssey orbiter using its THEMIS camera. The image was taken on A...

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.

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

This animation shows how NASA's Curiosity rover communicates with Earth via two of NASA's Mars orbiters, Mars Reconnaissance Orbiter (MRO) and Odyssey, and the European Space Agency's Mars Express....

The dunes in this VIS image are located in Aonia Terra.

Buzz Aldrin, an Apollo 11 astronaut who walked on the moon, makes a holographic appearance in 'Destination: Mars,' a mixed-reality tour of a part of Mars that NASA's Curiosity rover has explored.

This image combines two products from the first pointing at the Martian moon Phobos by the THEMIS camera on NASA's Mars Odyssey orbiter, on Sept. 29, 2017. Surface-temperature information from obse...

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...

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...

This rainbow-colored map shows underground water ice on Mars. Cool colors are closer to the surface than warm colors; black zones indicate areas where a spacecraft would sink into fine dust; the ou...

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 ...

Although this may look like a hostile alien life form, it's actually a complex line of sand dunes near the northern ice cap of Mars.

NASA Science missions circle Earth, the Sun, the Moon, Mars and many other destinations within our solar system, including spacecraft that look out even further into our universe. The Science Fleet...

Continuing our survey of non-crater dune fields brings us to this group of dunes in Aonia Terra. The daytime IR illustrates the warmth of the dune material compared to the surrounding materials.

This artist's animation shows how NASA's Curiosity rover will communicate with Earth via two of NASA's Mars orbiters, Mars Reconnaissance Orbiter and Odyssey. As the rover descends to the surface o...
