This image shows spidery channels eroded into Martian ground. It is an example from high-resolution observation of more than 20 places that were chosen in 2016 on the basis of about 10,000 volunteers' examinati More
This view from the Navigation Camera (Navcam) on the mast of NASA's Curiosity Mars rover shows rocky ground within view while the rover was working at an intended drilling site called "Precipice" on lower Mount More
This graphic depicts aspects of the driving distance, elevation, geological units and time intervals of NASA's Curiosity Mars rover mission, as of late 2016. The vertical dimension is exaggerated 14-fold compar More
This image from NASA Mars Reconnaissance Orbiter shows the growth of a branching network of troughs carved by thawing carbon dioxide over the span of three Martian years. This process is believed to also form l More
The network of cracks in this Martian rock slab called "Old Soaker" may have formed from the drying of a mud layer more than 3 billion years ago. The view spans about 4 feet (1.2 meters) left-to-right and combi More
A grid of small polygons on the Martian rock surface near the right edge of this view may have originated as cracks in drying mud more than 3 billion years ago. Multiple images from the Mast Camera (Mastcam) on More
This view shows part of an area on Mars where narrow rock ridges, some as tall as a 16-story building, intersect at angles forming corners of polygons. The area covered in the image spans about two-thirds of a More
This stereo view shows part of an area on Mars where narrow rock ridges, some as tall as a 16-story building, intersect at angles forming corners of polygons. It appears three-dimensional when viewed through r More
The left side of this 360-degree panorama from NASA's Curiosity Mars rover shows the long rows of ripples on a linear shaped dune in the Bagnold Dune Field on the northwestern flank of Mount Sharp. The view is More
This frame from a sequence of images shows a dust-carrying whirlwind, called a dust devil, scooting across the ground inside Gale Crater, as observed on the local summer afternoon of NASA's Curiosity Mars Rover More
This image from an animation shows effects of one Martian day of wind blowing sand underneath NASA's Curiosity Mars rover on a non-driving day for the rover. Each image was taken just after sundown by the rover More
Dust devils dance in the distance in this frame from a sequence of images taken by the Navigation Camera on NASA's Curiosity Mars rover on Feb. 12, 2017, during the summer afternoon of the rover's 1,607th Marti More
This is a portion of an inverted fluvial channel in the region of Aeolis/Zephyria Plana, at the Martian equator. Channels become inverted when the sediments filling them become more resistant to erosion than t More
This frame from a movie clip of hundreds of images from NASA's Mars Reconnaissance Orbiter shows a global map of Mars with atmospheric changes from Feb. 18, 2017 through March 6, 2017, a period when two regiona More
This false-color scene from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity documents movement of dust as a regional dust storm approached the rover's location on Feb. 24, 2017, durin More
Gullies eroded into the steep inner slope of an impact crater at this location appear perfectly pristine in this image captured by NASA's Mars Reconnaissance Orbiter (MRO). Although at first glance it may appea More
This view from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover shows two scales of ripples, plus other textures, in an area where the mission examined a linear-shaped dune in the Bagnold dune field on More
A Martian meteorite named Black Beauty recently shared secrets hidden deep inside thanks to powerful X-ray scanners at the U.S. Army Combat Capabilities Development Command’s Army Research Laboratory at Aberdee More
