Artist concept of Glaciers on Mars

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 image from NASA's Mars Reconnaissance Orbiter shows many new ice blocks compared to earlier images in 2006. One of the most actively changing areas on Mars are the steep edges of the North Pol...

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

CRISM observations of this region of the Noctis Labyrinthus formation have shown indications of iron-bearing sulfates and phyllosilicate (clay) minerals.

Nili Patera is a region on Mars in which dunes and ripples are moving rapidly. HiRISE continues to monitor this area every couple of months to see changes over seasonal and annual time scales.

This image shows part of the surface of Chryse Planitia, near the mouth of several of the giant outflow channels carved by massive floods. At this location the channel is much too large to be seen ...

This pair of before (left) and after (right) images from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter documents formation of a new channel on...

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.

This global map of Mars was acquired on July 31, 2012, by the Mars Color Imager instrument on NASA's Mars Reconnaissance Orbiter.

This graphic illustrates where Mars mineral-mapping from orbit has detected minerals that can indicate where a volcano erupted beneath an ice sheet. The site is far from any ice sheet on modern Mar...

This image, taken with the High Resolution Imaging Science Experiment (HiRISE) camera, shows distinct bands of alternating tone and brightness within the "Murray Formation" on Mars.

This global map of Mars was acquired on Aug. 4, 2012, by the Mars Color Imager instrument on NASA's Mars Reconnaissance Orbiter.

This map shows the thickness of the north polar layered deposits on Mars as measured by the Shallow Radar instrument on NASA's Mars Reconnaissance Orbiter.

NASA's Curiosity rover and its parachute were spotted by NASA's Mars Reconnaissance Orbiter as Curiosity descended to the surface on Aug. 5 PDT (Aug. 6 EDT).

Artist’s concept of Comet Siding Spring approaching Mars, shown with NASA’s orbiters preparing to make science observations of this unique encounter.

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. 

Intra-Crater Structure in NW Hellas Basin, Mars

This image shows details of the lava covered plains near the equator of Mars. The darker looking area has a rough lava surface with all the shadows giving the region a darker appearance.

This June 27, 2014, image from the HiRISE camera on NASA's Mars Reconnaissance Orbiter shows NASA's Curiosity Mars rover on the rover's landing-ellipse boundary, which is superimposed on the image.

This anaglyph from HiRISE shows erosional features formed by seasonal frost near the south pole of Mars.

Two types of wind-blown sedimentary deposits are pictured in this scene of the floor of Ius Chasma in the Valles Marineris.

The Mars Reconnaissance Orbiter took this photo of the Curiosity rover in September 2015, as Curiosity was exploring the boundary between two rock units: the light-toned Murray Formation and the ov...

This image acquired on December 8, 2018 by NASAs Mars Reconnaissance Orbiter, shows erosion of the surface revealing several shades of light toned layers, likely sedimentary deposits.

A towering dust devil casts a serpentine shadow over the Martian surface in this image acquired by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.

This animation shows NASA's Mars Reconnaissance Orbiter flying over NASA's Curiosity (shown in pink) as the rover lands on the Red Planet. The video is slowed down as the orbiter approaches the lan...
