Wrinkle Ridge, Solis Planum

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...

Dunes on Floor of Samara Valles, Mars

A meteorite impact that excavated this crater on Mars exposed bright ice that had been hidden just beneath the surface at this location.

This animation shows NASA's Mars Reconnaissance Orbiter flying over NASA's Curiosity (shown in pink) as the rover lands on the Red Planet. The video is slowed down as the orbiter approaches the lan...

What triggered a Martian landslide? Landslides are common features in canyons on both Earth and Mars, and they happen the same way.

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

This image provides higher-resolution views of a site where another observation (PIA10247) indicates the presence of chloride salt deposits.

These collapse pits probably formed when lava erupted from the side of Arsia Mons, draining underground magma reservoirs. The resulting voids collapse due to the weight of the solid lava above them...

This image taken on May 19, 2010, shows an impact crater that had not existed when the same location on Mars was previously observed in March 2008.

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter captured winter images of NASA's Phoenix Mars Lander surrounded by dry-ice frost on Mars.

This image acquired on December 5, 2018 by NASAs Mars Reconnaissance Orbiter, shows ripples in the sand which tell us which way the wind was moving and how it was diverted around these rock formati...

Artist's concept of Mars Reconnaissance Orbiter near Mars.

With the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument just above his head, a technician at NASA’s Kennedy Space Center works on the Mars Reconnaissance Orbiter spacecraft...

This color-enhanced view shows the terrain around the rover's landing site within Gale Crater on Mars.

Light-Toned Bedrock Along Cracks as Evidence of Fluid Alteration.

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

The South Polar residual cap (the part that lasts through the summer) is composed of carbon dioxide ice.

This movie begins with an animation (artist's rendering) of NASA's Mars Reconnaissance Orbiter spacecraft above Mars. The scene zooms into an "X-ray" view of the spacecraft, revealing the High Reso...

This pair of images taken one day apart by the Mars Color Imager (MARCI) weather camera on NASA's Mars Reconnaissance Orbiter reveals when an asteroid impact made the scar seen in the right-hand im...

This map of Mars shows relative locations of three types of findings related to salt or frozen water, plus a new type of finding that may be related to both salt and water.

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...

CRISM observations of this region of the Noctis Labyrinthus formation have shown indications of iron-bearing sulfates and phyllosilicate (clay) minerals.
