This image shows an example of layers in the Martian north polar deposits. These deposits, part of the Planum Boreum dome, are composed mainly of water ice and small amounts of dust.

This image from NASA's Mars Reconnaissance Rover shows the edge of a mound of ice in one of the mid-latitude craters. Scientists now realize that ice is very common on the Martian surface.

NASA's Mars Exploration Rover Opportunity has been on the western rim of Endeavour Crater in Meridiani Planum for about two years. Until May 2013, it was investigating sedimentary layers that are ...

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. 

This is an image of Gusev Crater taken by the Mars Reconnaissance Orbiter HiRISE camera and is one of the potential landing sites for the Mars 2020 rover.

Dust-Mantled Topography near Zephyria Tholus

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.

This map traces where NASA's Mars rover Curiosity drove between landing at a site subsequently named "Bradbury Landing," and the position reached during the mission's 130th Martian day, or sol, (De...

Shalbatana Vallis is a large channel with steep walls and a flat floor that may have formed by water draining from nearby Ganges Chasma. Here a section of the wall collapsed and produced a landslid...

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.

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 May 2015 image from the HiRISE camera on NASA's Mars Reconnaissance Orbiter shows a location on Mars associated with the best-selling novel and Hollywood movie, "The Martian." It is in a regio...

A meteorite impact that excavated this crater on Mars exposed bright ice that had been hidden just beneath the surface at this location.

This color thumbnail image was obtained by NASA's Curiosity rover during its descent to the surface of Mars on Aug. 5 PDT (Aug. 6 EDT).

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

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 Reconnaissance Orbiter (MRO) keeps finding new impact sites on Mars. This one occurred within the dense secondary crater field of Corinto Crater. The new crater and its ejecta have dist...

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 sinuous raised ridge is thought to be an inverted stream channel.  These are formerly low-lying streambeds that became elevated because the original depression is filled with materials (such a...

This graphic shows the route that NASA's Mars Exploration Rover Opportunity drove in its final approach to "Perseverance Valley" on the western rim of Endeavour Crater during spring 2017.

NASA's Mars Reconnaissance Orbiter dips into the thin martian atmosphere to adjust its orbit in this artist's concept illustration.

This HiRISE image shows gullies on a south-facing slope of a crater touched with late-Spring carbon dioxide frost. At this time of year, only the south-facing slopes of craters retain their frost, ...

A radar on NASA's Mars Reconnaissance Orbiter has detected widespread deposits of glacial ice in the mid-latitudes of Mars.

This map of Mars shows relative locations of three types of findings related to salt or frozen water, plus a new type of finding that may be related to both salt and water.
