Landing Site Region

NASA's Mars Reconnaissance Orbiter has been observing Mars since 2006, enabling it to document many types of changes, such as the way winds alter the appearance of this recent impact site. The orbi...

NASA's Mars Reconnaissance Orbiter arrived at Mars on March 10, 2006. Over the past decade, the mission has shown how dynamic Mars remains today, as well as how diverse its past environmental condi...

By analyzing radar images like the one at top of this montage, scientists discovered evidence for a past ice age in the northern polar ice cap of Mars.

Images of locations in Gale Crater taken from orbit around Mars reveal evidence of erosion in recent geological times and development of small scarps, or vertical surfaces.

Newly detailed mapping of local variations in Mars' gravitational pull on orbiters (center), combined with topographical mapping of the planet's mountains and valleys (left), yields the best-yet ma...

This dune field in Aonia Terra shows sand dunes with a variety of morphologies. These complex shapes often indicate that the dominating winds change direction, either over time or from one locatio...

Common to the northern plains of Mars are rock and boulder strewn landscapes otherwise devoid of major features except a few impact craters. This image in the Cydnus Rupes region of northern Utopia...

'Marsshine' on Shadowed Part of Phobos

This image from NASA's Mars Reconnaissance Orbiter shows an impact crater that triggered a slope streak. When a meteoroid hit the surface and exploded to make the crater, it destabilized the slope ...

This is a small volcano superposed on the flanks of a larger one of the Cerberus Tholi. 

This map indicates some of the geological information gained from orbital observations of Endeavour Crater, which has been the long-term destination for NASA's Mars Exploration Rover Opportunity si...

This is a diagram that shows the launch phases for the Mars Reconnaissance Orbiter.

Syrtis Major Region

The largest crater in this mosaic of images taken by the Context Camera on NASA's Mars Reconnaissance Orbiter is Endeavour Crater, which is 22 kilometers (14 miles) in diameter.

Impact cratering and erosion combine to reveal the composition of the Martian underground by exposing materials from the subsurface.

This DLE [double layer ejecta] crater formed at the edge of an older/pre-existing crater, the rim of which deflected some of its ejecta.

Is frozen carbon dioxide a key to features in some Martian gullies? To find out, scientists grabbed a bag of dry ice and took a road trip.

Mars' north polar deposits comprise a thick stack of icy layers. Part of this image from NASA's Mars Reconnaissance Orbiter (MRO) has lingering seasonal frost, which serves to accentuate those laye...

This HiRISE image shows a group of cones, shield-like features, and round mounds.

This movie clip shows a global map of Mars with atmospheric changes from Feb. 18, 2017, through March 6, 2017, a period when two regional-scale dust storms appeared. It combines hundreds of images ...

Dark, narrow streaks on Martian slopes such as these at Horowitz Crater are inferred to have been formed by seasonal flow of water on contemporary Mars. Detection of hydrated salts at the streaks s...

This image, taken Jan. 26, 2012, shows NASA's no-longer-active Phoenix Mars Lander spacecraft after its second Martian arctic winter.

This animation shows the position of NASA's Curiosity rover as it journeyed through "the clay-bearing unit" on Mars between May 31 and July 20, 2019. The HiRISE camera on NASA's Mars Reconnaissance...

This image covers a region of Mars near Nili Fossae that contains some of the best exposures of ancient bedrock on Mars.

The black speck circled in the lower left corner of this image is a cluster of recently formed craters spotted on Mars using a new machine-learning algorithm. This image was taken by the Context Ca...
