Storm Chaser on Mars

The linearity of the volcanic vent shown in this HiRISE image, in conjunction with evidence of lava flow from the vent, suggests control by combined volcano-tectonic processes.

The High-Resolution Imaging Science Experiment (Hi-RISE) camera aboard NASA's Mars Reconnaissance Orbiter captured this avalanche plunging down a 1,640-foot-tall (500-meter-tall) cliff on May 29, 2...

A view from NASA's Mars Reconnaissance Orbiter on April 8, 2015, catches sight of NASA's Curiosity Mars rover passing through a valley called "Artist's Drive" on the lower slope of Mount Sharp.

NASA's Mars Reconnaissance Orbiter dips into the thin martian atmosphere to adjust its orbit in this artist's concept illustration.

NASA's Mars Reconnaissance Orbiter has clocked more than a decade of service at the Red Planet and has yielded scientific discoveries and magnificent views of a distant world. These images taken by...

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter caught this view of NASA's Mars Exploration Rover Opportunity on Feb. 14, 2014.

This enhanced image shows the inside of a rimless pit about 180 meters (591 feet) in diameter, northwest of the mountain Ascraeus Mons in the northern hemisphere of Mars.

This color image from NASA's Mars Reconnaissance Orbiter (MRO) shows bedrock layers of diverse colors and composition.

Back-and-forth blinking of this two-image animation shows movement of a sand dune on Mars. The images are part of a study published by Nature on May 9, 2012, reporting movement of Martian sand dune...

This image is an artist's concept of a view looking down on NASA's Mars Reconnaissance Orbiter. The spacecraft is pictured using its Shallow Subsurface Radar instrument (SHARAD) to "look" under the...

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...

The HiRISE camera on the Mars Reconnaissance Orbiter is the most powerful telescope to have left Earth orbit. HiRISE is capable of some interesting astronomical observations such as this image of J...

Well-Preserved Crater with Central Peak in Chryse Planitia

This map of an area within the Arabia Terra region on Mars shows where hydrologic modeling predicts locations of depressions that would have been lakes (black), overlaid with a map of the preserved...

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!

This HiRISE image shows fractured mounds on the southern edge of Elysium Planitia.

This enhanced-color image shows sand dunes trapped in an impact crater in Noachis Terra, Mars.

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...

Polygons are of great interest because they often indicate the presence of shallow ice or of desiccation such as in a mud flat. However, nature sometimes seems too clever for us.

This Southern autumn image captures a view of frosty dunes. The sunlight is shining on the dunes from the upper right.

This is a small volcano superimposed on the flanks of a larger one of the Cerberus Tholi.

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...
