Artist concept of Glaciers on Mars

Overview map showing the location of the study area within Aeolis Dorsa (star).

This image maps the traverse of NASA's Mars rover Curiosity from "Bradbury Landing" to "Yellowknife Bay," with an inset documenting a change in the ground's thermal properties with arrival at a dif...

The yellow-white cloud in the bottom-center of this image is a Mars "dust tower" — a concentrated cloud of dust that can be lofted dozens of miles above the surface. The blue-white plumes are water...

This image, acquired on January 2, 2014, by NASA's Mars Reconnaissance Orbiter, shows dune fields located among canyon wall slopes.

Drainage Near Crater in Terra Sabaea.

This view shows a full-resolution portion of the first image of Mars taken by the High Resolution Imaging Science Experiment camera (HiRISE) on NASA's Mars Reconnaissance Orbiter.

This image shows a graben (a trough formed when the ground drops between two parallel faults) and a lava flow in the Tharsis volcanic province of Mars. North is up.

The colorful rocks exposed in the central peak visible in this image probably reflect variations in mineral content that were caused by water activity early in Mars' history. The CRISM hyperspectra...

The total distance driven by NASA's Mars rover Curiosity passed the one-mile mark a few days before the first anniversary of the rover's landing on Mars.

This map shows the route driven by NASA's Curiosity Mars rover from the "Bradbury Landing" location where it landed in August 2012 (the start of the line in upper right) to a major waypoint called ...

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...

The High-Resolution Imaging Science Experiment aboard NASA's Mars Reconnaissance Orbiter provides this view of Olympus Mons, the tallest known volcano in the solar system.

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 March 20, 2014, image from the MARCI camera on NASA's Mars Reconnaissance Orbiter has a dark spot (at center of inscribed rectangle) noticed while the image was being examined for a weather re...

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...

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter took two images of the larger of Mars' two moons, Phobos, within 10 minutes of each other on Mar...

This image shows the landing site of NASA's Curiosity rover and destinations scientists want to investigate.

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).

This area at the base of Mount Sharp on Mars includes a pale outcrop, called "Pahrump Hills," that NASA's Curiosity Mars rover investigated from September 2014 to March 2015, and the "Artist's Driv...

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 ...

Crater Floor Deposits in Promethei Terra

A regional dust storm visible in the southern hemisphere of Mars in this nearly global mosaic of observations made by the Mars Color Imager on NASA's Mars Reconnaissance Orbiter on Nov. 25, 2012.

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

The Mars Reconnaissance Orbiter’s Context Camera, which captured the 110,000 images that make up the interactive global mosaic, is especially useful for spotting impact craters like those seen here.
