Artist concept of Glaciers on Mars

This map shows the route driven by NASA's Curiosity Mars rover from the location where it landed in August 2012 to its location in September 2016 at "Murray Buttes," and the path planned for reachi...

Phobos from 6,800 Kilometers

Recurring slope lineae (RSL) are active flows on warm Martian slopes that might be caused by seeping water.

This image, taken Jan. 26, 2012, shows the back shell of NASA's Phoenix Mars Lander spacecraft after its second Martian arctic winter.

This image from the NASA Mars Reconnaissance Orbiter shows an impact scar on Mars made by pieces of the NASA Mars Science Laboratory spacecraft that the spacecraft shed just before entering the Mar...

This map shows the route driven by NASA's Mars rover Curiosity through the 29th Martian day, or sol, of the rover's mission on Mars (Sept. 4, 2012).

These two images show Shallow Radar (SHARAD) instrument data from two tracks in a part of Mars' Utopia Planitia region where the orbiting, ground-penetrating radar on NASA's Mars Reconnaissance Orb...

Explanation on how CRISM hyperspectral images are used to understand the history and formation of Valles Marineris, one of the largest canyons in the solar system, and how the data is used to unrav...

NASA's Mars Exploration Rover Opportunity has been on the western rim of Endeavour Crater in Meridiani Planum for about two years.

Syrtis Major Region

This image acquired on August 20, 2018 by NASAs Mars Reconnaissance Orbiter, shows remnants of a deposit, composed of dry ice layered together with dust and water ice, that form the south polar res...

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 image from NASA's Mars Reconnaissance Orbiter shows Aram Chaos, an ancient impact crater that lies within in the Southern Highlands of Mars. Uplifted blocks are composed largely of the iron-ox...

NASA's Mars rover Curiosity left the "Glenelg" area on July 4, 2013, on a "rapid transit route" to the entry point for the mission's next major destination, the lower layers of Mount Sharp.

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.

This image from NASA's Mars Reconnaissance Orbiter is a close-up of a trough, along with channels draining into the depression. On the floor of the trough is some grooved material typically seen in...

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter acquired this color image on March 9, 2011, of "Santa Maria" crater, showing NASA's Mars Explora...

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

Stokes Crater, pictured here, is one of at least nine craters in the northern lowlands of Mars with exposures of hydrated minerals detected from orbit, according to a June 25, 2010, report.

The eastern margin of a rippled dune in Herschel Crater on Mars moved an average distance of three meters (about three yards) between March 3, 2007 and December 1, 2010, as seen by NASA's Mars Reco...

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

Details of hilly terrain within a large Martian canyon are shown on a geological map based on observations from NASA's Mars Reconnaissance Orbiter and produced by the U.S. Geological Survey.

This scene is from early spring in the northern hemisphere of Mars. These dunes are covered with a layer of seasonal carbon dioxide ice (dry ice).

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...
