Storm Chaser on Mars

This global map of Mars was acquired on July 31, 2012, by the Mars Color Imager instrument on NASA's Mars Reconnaissance Orbiter.

This graph shows a spectrum recorded by the Chemistry and Camera instrument (ChemCam) in NASA's Curiosity Mars rover.

This 3D, or stereo anaglyph, view shows the parachute and back shell that helped guide NASA's Curiosity to the surface of Mars. The view was produced from images taken by the High Resolution Imagin...

This April 6, 2014, image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter shows numerous landslides in the vicinity of where an impact crat...

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...

NASA's Phoenix Mars Lander, its backshell and its heatshield are visible within this enhanced-color image of the Phoenix landing site taken on Jan. 6, 2010 by the High Resolution Imaging Science Ex...

This proposed future Mars landing site in Acidalia Planitia targets densely occurring mounds thought to be mud volcanoes.

This area of Mars is shaped by lava flows from volcanic eruptions.

Gullies and Flow Features along Crater Wall in Promethei Terra

A dune in the northern polar region of Mars shows significant changes between two images taken on June 25, 2008 and May 21, 2010 by NASA's Mars Reconnaissance Orbiter.

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

NASA's Curiosity Mars rover can be seen in this image taken from space on May 31, 2019, by the HiRISE camera aboard the Mars Reconnaissance Orbiter. In the image, Curiosity appears as a bluish speck.

As on the Earth, many processes can move material down a Martian slope. This graphic compares seven different types of features observed on Mars that appear to result from material flowing or slidi...

This picture of a crater resembling a "happy face" was taken by the Mars Reconnaissance Orbiter's Context Camera. The unnamed crater is almost 2 miles (about 3 kilometers) across That's a BIG smile!

Curiosity performs the first investigation of active sand dunes on another planet. Studying the Bagnold Dunes on Mars will help scientists understand the physics of Martian dunes and how they move.

The enhanced-color subimage shows a great variety of colors and textures in the bedrock, where it is exposed from beneath a dark fine-grained mantle. The mantle is sometimes modified by the wind in...

The black speck circled in the lower left corner of this image is a cluster of recently formed craters spotted on Mars using a new machine-learning algorithm. This image was taken by the Context Ca...

A small channel cuts across the floor of a gigantic 1100-mile (1780-kilometer)-long set of flood-carved channels in a region on Mars called "Kasei Valles."

This image, acquired on May 15, 2018, by NASA's Mars Reconnaissance Orbiter, shows relatively bright mounds scattered throughout darker and diverse surfaces in Chryse Planitia.

On this map of Mars, areas indicated in green are where spectrometers on spacecraft orbiting Mars have detected clay minerals and areas indicated in blue are where those spectrometers have detected...

Common to the northern plains of Mars are rock and boulder strewn landscapes otherwise devoid of major features except a few impact craters. This image in the Cydnus Rupes region of northern Utopia...

This map shows the route driven by NASA's Mars rover Curiosity through the 29th Martian day, or sol, of the rover's mission on Mars (Sept. 4, 2012).

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

This HiRISE image shows diverse layers in a region near Mawrth Vallis, a channel that was probably carved by water in Mars' ancient past. The color subimage shows details of layers exposed in a cra...

NASA's Curiosity Mars rover and tracks left by its driving appear in this portion of a Dec. 11, 2013, observation by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Re...
