Storm Chaser on Mars

Mars' north polar deposits comprise a thick stack of icy layers. Part of this image from NASA's Mars Reconnaissance Orbiter (MRO) has lingering seasonal frost, which serves to accentuate those laye...

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...

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

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

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...

Dark, seasonal flows emanate from bedrock exposures at Palikir Crater on Mars in this image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.

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 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...

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 ...

Shown here is a stereo pair of a well-preserved impact crater about 6 or 7 kilometers wide from rim to rim.

This image shows an outcrop of the south polar layered deposits (SPLD). The SPLD consist of layers of ice and admixed dust and make up the bulk of the dome-shaped Planum Australe.

Blue dots on this map indicate sites of recurring slope lineae (RSL) in part of the Valles Marineris canyon network on Mars. RSL are seasonal dark streaks that may be indicators of liquid water. Th...

Hitting a moving target over 306 million miles away is no easy feat. Learn how JPL navigation engineers have guided the Mars Reconnaissance Orbiter toward its mission-critical capture into orbit ar...

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

Nili Fossae was once considered a potential landing spot for the Mars Science Laboratory, and has one of the largest, most diverse exposures of clay minerals.

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.

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 sequence of images shows a blast zone where the sky crane from NASA's Curiosity rover mission hit the ground after setting the rover down in August 2012, and how that dark scar's appearance ch...

Mysterious features on slopes hint there could be water flows on Mars.

This image shows the quadrangle where NASA's Curiosity rover landed, now called Yellowknife.

Women working in science, technology, engineering and mathematics at NASA's Jet Propulsion Laboratory pose for a photo in mission control in honor of Women in Science Day.

This map shows the route on lower Mount Sharp that NASA's Curiosity followed between April 19, 2015, and Nov. 5, 2015. During this period the mission investigated silica-rich rock targets includin...

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 ...

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).

This image shows part of the surface of Chryse Planitia, near the mouth of several of the giant outflow channels carved by massive floods. At this location the channel is much too large to be seen ...
