Crater Floor Deposits in Promethei Terra

Eberswalde Crater was one of the four final landing sites considered for the MSL rover. A channel leads into the crater and the lithified remains of a delta, a fan-like feature formed when sediment...

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.

Lucus Planum is a part of the enigmatic Medusa Fossae Formation, a broad, soft, and easily eroded deposit. Here this deposit is thin and considerably rougher than elsewhere, implying that it is hea...

This animation flips back and forth between views taken in 2010 and 2014 of a Martian sand dune at the edge of Mount Sharp, documenting dune activity. The images are from the HiRISE camera on NASA'...

Images acquired Jan. 9, 2022, from the Mars Color Imager instrument on NASA’s Mars Reconnaissance Orbiter were combined to create this view showing the presence of a regional dust storm obscuring t...

As the Sun peeks above the horizon at the Martian south polar icecap, powerful jets of carbon-dioxide (CO2) gas erupt through the icecap's topmost layer.

This picture of a heart-shaped feature in Arabia Terra on Mars was taken on May 23, 2010, by the Context Camera (CTX) on NASA's Mars Reconnaissance Orbiter.

This pair of images covers one of many sites on Mars where researchers use the HiRISE camera on NASA's Mars Reconnaissance Orbiter to study changes in gullies on slopes. Changes such as the ones v...

The arm and the remote sensing mast of the Mars rover Curiosity each carry science instruments and other tools for NASA's Mars Science Laboratory mission.

This image shows a cross-section of a portion of the north polar ice cap of Mars, derived from data acquired by the Mars Reconnaissance Orbiter's Shallow Radar (SHARAD), one of six instruments on t...

Unfrozen brine in cryopegs and fracture networks provides habitats for the survival and growth of organisms both within and under frozen rocky materials on Earth and, by analogy, could provide habi...

This view of an inverted crater in the Arabia Terra region of Mars is among the images taken by NASA's Mars Reconnaissance Orbiter in early 2010 as the spacecraft approached the 100-terabit milesto...

This view of a portion of the Eridania region of Mars shows blocks of deep-basin deposits that have been surrounded and partially buried by younger volcanic deposits. The image was taken by the Con...

These views of sites where hardware from Europe's Schiaparelli test lander hit Mars on Oct. 19, 2016, combine two HiRISE camera orbital views from different angles, as a stereo pair for viewing wit...

This kickoff of a new Mars video series covers Opportunity's 14th anniversary on the Red Planet, Curiosity's spectacular panorama and ice deposits spotted by an orbiter.

This inner slope of a Martian crater has several of the seasonal dark streaks called "recurrent slope lineae," or RSL, that a November 2017 report interprets as granular flows, rather than darkenin...

This image acquired on March 29, 2011 by NASAs Mars Reconnaissance Orbiter, shows dunes with ripples on their upwind slopes and dark streaks on their downwind slopes.

Eridania Region Outcrops

This image lies in the middle of a candidate landing site in the Northeast part of Syrtis Major, a huge shield volcano, and near the Northwest rim of Isidis Planitia, a giant impact basin.

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.

Caught in Action: This image shows avalanches on North Polar Scarps.

The Coloe Fossae region is a series of enclosed, intersecting canyons. The floors of the canyons in this image contain complex set of ridges and grooves that are generally parallel to the canyon wa...

This image shows part of Ladon Vallis, a long outflow channel found in the Southern Highlands on Mars.

NASA's Mars Reconnaissance Orbiter, nearing the 10th anniversary of its arrival at Mars, used its High Resolution Imaging Science Experiment (HiRISE) camera to obtain this view of an area with unus...

From one side of the country to the other, through a snowstorm and other delays, the Mars Reconnaissance Orbiter made its way to Kennedy Space Center in Florida for final processing and rehearsals ...
