Syrtis Major Region

Aram Chaos is a heavily eroded impact crater that contains jumbled blocks of material disrupted when large quantities of ice or water were catastrophically removed. The light toned sediments may ha...

Before and after images from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter illustrate occurrence of new streaks on the slip face of a dark san...

This large outflow channel shows many characteristic signs that massive amounts of water have flowed through this area, including the teardrop and streamlined islands.

This image shows the context for orbital observations of exposed rocks that had been buried an estimated 5 kilometers (3 miles) deep on Mars.

This image shows a portion of the central mound in the impact crater Gale that is of interest to scientists because it is composed of light-toned layered deposits. 

At the center of this view of an area of mid-latitude northern Mars, a fresh crater about 6 meters (20 feet) in diameter holds an exposure of bright material, blue in this false-color image.

These images show a 256 x 256 pixel patch of sky at the range to the comet of 8 million miles and when the solar phase angle is 47 degrees.

Getting a spacecraft to Mars is no walk in the park - as launch engineers are well aware. But when the spacecraft in question is among the largest ever sent to the red planet, there are specific ch...

The Mars Climate Sounder instrument, shown here prior to its installation onto NASA's Mars Reconnaissance Orbiter for the mission's 2006 launch, will get a similar-looking sibling at Mars in 2016.

This sequence of images shows a blast zone where the sky crane from NASA's Curiosity rover mission hit the ground after setting the rover down in August 2012, and how that dark scar's appearance ch...

This series of images shows warm-season features that might be evidence of salty liquid water active on Mars today.

Phobos from 6,800 Kilometers

On Mars the seasonal polar caps are composed of dry ice (carbon dioxide). In the springtime as the sun shines on the ice, it turns from solid to gas and causes erosion of the surface

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 HiRISE image shows a mixture of bright and dark units. The bright units have a mineral called sulfate (salty sulfuric acid) that on Earth typically forms in the presence of water as an evapori...

Artist rendering of commercial Mars satellites providing communications back to Earth.

This view combines information from two instruments on NASA's Mars Reconnaissance Orbiter to map color-coded composition over the shape of the ground in a small portion of the Nili Fossae plains re...

The logistical challenge of getting a mission sent to Mars begins years before liftoff and culminates in the stressful days just prior to launch. This video highlights teams at JPL, Kennedy Space C...

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter snapped this series of false-color pictures of sand dunes in the north polar region of Mars.

Two 2001 images from NASA's Mars Global Surveyor orbiter show a dramatic change in the planet's appearance during a dust storm.

This artist's concept of the Mars Reconnaissance Orbiter features the spacecraft's main bus facing down, toward the red planet.

NASA's Mars Reconnaissance Orbiter shows bright ripples line the topography in this region, formed within a past climate. Dark dunes and sand streaks, composed of basaltic sand, have moved and fill...

The Russell Crater dune field is covered seasonally by carbon dioxide frost, and this image shows the dune field after the frost has sublimated (evaporated directly from solid to gas). There are ju...

These images from the NASA Mars Reconnaissance Orbiter show several impact scars on Mars made by pieces of the NASA Mars Science Laboratory spacecraft that the spacecraft shed just before entering ...
