Meridiani Planum

This artist's concept shows NASA's Mars orbiters lining up behind the Red Planet for their "duck and cover" maneuver to shield them fro comet dust that may result from the close flyby of comet Sidi...

This image from NASA's Mars Odyssey shows a crater from a double impact - two meteors hitting simultaneously. The two meteors would have started as a single object and, at some point prior to impac...

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.

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.

A dust storm continues to envelop the Red Planet and Curiosity’s labs are back in action.

Researchers estimating the amount of carbon held in the ground at the largest known carbonate-containing deposit on Mars utilized data from three different NASA Mars orbiters.

This image is near the southern edge of a low, broad volcanic feature called Syrtis Major.

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...

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 ...

A sea of dark dunes, sculpted by the wind into long lines, surrounds the northern polar cap covering an area as big as Texas.

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...

Spider Web Pattern

This THEMIS image of rounded hills and ridges in Arcadia Planitia shows a very intriguing geomorphic feature that may be attributed to the presence of an icy-rock mixture of material. Smooth aprons...

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...

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 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).

This mosaic of day and night infrared THEMIS images shows landslides flowed over 100 kilometers (62 miles) across the floor of Melas Chasma.

This series of images was taken in visible-wavelength light as the THEMIS camera on NASA's Mars Odyssey scanned across the Martian moon Phobos on Sept. 29, 2017. The apparent motion is due to progr...

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....
