Eridania Region Outcrops

This HiRISE image shows a valley filled with an assortment of linear ridges. These ridges are often referred to as transverse aeolian ridges, or TAR, and they take a variety of forms.

This April 6, 2014, image from the Context Camera on NASA's Mars Reconnaissance Orbiter was taken as a follow-up to discovery of a possible 2012 impact scar in images from the orbiter's Mars Color ...

The logistical challenge of getting a mission sent to Mars begins years before liftoff and culminates in the stressful days just prior to launch. This video highlights teams at JPL, Kennedy Space C...

A lunar eclipse, a solar eclipse and Mars has a close encounter with a comet.

Gale Crater forms a large natural repository for much of Martian geologic history.

This image acquired on December 3, 2018 by NASAs Mars Reconnaissance Orbiter, shows a cross-section of a dune field. Dune shape depends on several factors, including the amount of sand present and ...

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 December 2015, at examples of the Bagnold Dunes.

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...

This image shows part of the floor of an impact crater on the northern rim of the giant Hellas Basin.

This animation shows the position of NASA's Curiosity rover as it journeyed through "the clay-bearing unit" on Mars between May 31 and July 20, 2019. The HiRISE camera on NASA's Mars Reconnaissance...

This set of images shows "before" and "after" images of NASA's Phoenix Mars Lander taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.

Intra-Crater Structure in NW Hellas Basin, Mars

This false-color animation simulates a fly-around look at one of the places on Mars where dark streaks advance down slopes during warm seasons, possibly involving liquid water or brine. This site i...

Mawrth Vallis is one of the oldest valleys on Mars, formed in and subsequently covered by layered rocks, which are now exposed due to erosion. Mars orbiters have observed clay minerals that form in...

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...

The Eridania basin of southern Mars is believed to have held a sea about 3.7 billion years ago, with seafloor deposits likely resulting from underwater hydrothermal activity. This graphic shows est...

In February 2015, NASA's Mars Exploration Rover Opportunity is approaching a cumulative driving distance on Mars equal to the length of a marathon race. This map shows the rover's position relative...

This image from the HiRISE camera on NASA's Mars Reconnaissance Orbiter shows a location associated with the novel and movie, "The Martian." It is the tale's planned landing site for the Ares 4 mis...

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

This image shows the topography, with shading added, around the area where NASA's Curiosity rover landed on Aug. 5 PDT (Aug. 6 EDT).

An enhanced-color image from NASA's Mars Reconnaissance Orbiter (MRO) reveals bedrock that is several kilometers below the top of the giant Valles Marineris canyons.

This image from NASA's Mars Reconnaissance Orbiter (MRO) shows the western wall of a small pit that is located along the floor of a larger trough in Coprates Catena. Dark layers line the bottom; li...

This diagram illustrates an interpretation for the origin of some deposits in the Eridania basin of southern Mars as resulting from seafloor hydrothermal activity more than 3 billion years ago.

NASA's Curiosity Mars rover used its Navigation Camera (Navcam) to record this stereo scene of a butte called "Mount Remarkable" and surrounding outcrops at a waypoint called "the Kimberley" inside...

This map shows the route driven by NASA's Mars rover Curiosity through the 43rd Martian day, or sol, of the rover's mission on Mars (Sept. 19, 2012).
