Storm Chaser on Mars

This image shows NASA's Mars Exploration Rover Opportunity perched on the edge of "Concepción" crater in Meridiani Planum, Mars.

This fresh crater is located in the northern mid-latitudes. It is designated as fresh because of its very sharp rim.

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 illustration schematically shows where the Shallow Radar instrument on NASA's Mars Reconnaissance Orbiter detected flood channels that had been buried by lava flows in the Elysium Planitia reg...

Small impact craters usually have simple bowl shapes, but sometimes more complicated shapes can occur if the target is unusual.

This image, taken by HiRISE, shows a lobate tongue on the Northwest Hellas rim.

The Mars Color Imager (MARCI) camera on NASA's Mars Reconnaissance Orbiter acquired a seven-band color, wide-angle view of Mars on March 24, 2006, as part of a checkout of the orbiter's payload. Th...

HiRISE image of Planum Chronium Region.

This area at the base of Mount Sharp on Mars includes a pale outcrop, called "Pahrump Hills," that NASA's Curiosity Mars rover investigated from September 2014 to March 2015, and the "Artist's Driv...

Terrain in Vastitas Borealis Region.

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 ...

This animation simulates a flyover of a portion of a Martian canyon detailed in a geological map produced by the U.S. Geological Survey and based on observations by NASA's Mars Reconnaissance Orbit...

Eridania Basin Light-Toned Outcrops

This illustration depicts a concept for the possible extent of an ancient lake inside Gale Crater.

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 contrasts gullies and recurring warm-season slope flows appearing in the same crater, in the middle southern latitudes of Mars.

Five decades of successful NASA missions to the Red Planet, 1965-2015.

This image shows the landing site of NASA's Curiosity rover and destinations scientists want to investigate.

More evidence of a dynamic Mars is revealed at the edge of a martian dune field.

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.

These dunes may be active today, but we haven't yet observed them at significantly different times to measure the movement.

In early 2017, after more than a decade of observing Mars, the Context Camera on NASA's Mars Reconnaissance Orbiter (MRO) surpassed 99 percent coverage of the entire planet. This mosaic shows that...

This global map of Mars was acquired on Aug. 2, 2012, by the Mars Color Imager instrument on NASA's Mars Reconnaissance Orbiter.

NASA's Curiosity Mars rover and tracks from its driving are visible in this view from orbit, acquired on April 11, 2014, by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's ...

This map shows the location of "Cumberland," the second rock-drilling target for NASA's Mars rover Curiosity, in relation to the rover's first drilling target, "John Klein," within the southwestern...
