Replicating Martian Dunes

This movie clip shows the larger of Mars' two moons, Phobos, passing in front of the smaller Martian moon, Deimos, as observed by NASA's Mars rover Curiosity.

Two images from the Mast Camera (Mastcam) on NASA's Curiosity rover depicting the change in the color of light illuminating the Martian surface since a dust storm engulfed Gale Crater. The left ima...

Top of Mars Rover Curiosity's Remote Sensing Mast

This close-up view of a stone found in San Diego was taken by a testing twin -- the "life test unit" -- of the Mars Hand Lens Imager (MAHLI) camera for NASA's Mars Science Laboratory.

This 360-degree panorama was taken on Aug. 9 by NASA's Curiosity rover at its location on Vera Rubin Ridge. 

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

This view combines several frames taken by the Mast Camera (Mastcam) on NASA's Mars rover Curiosity, looking into a valley to the west from the eastern side of a dune at the eastern end of the valley.

This mosaic from the Mast Camera on NASA's Curiosity rover shows a close-up view looking toward the "Glenelg" area, where three different terrain types come together.

This map shows the route driven by NASA's Mars rover Curiosity through the 56th Martian day, or sol, of the rover's mission on Mars (Oct. 2, 2012).

This scene combines images taken by the left-eye camera of the Mast Camera (Mastcam) instrument on NASA's Curiosity Mars rover during the midafternoon, local Mars solar time, of the mission's 526th...

Mastcam 100: Longer Focal-Length Eye of Mast Camera Pair for Mars Rover

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.

This artist's concept depicts the moment immediately after NASA's Curiosity rover touches down onto the Martian surface.

Pictured here is Clara Ma (in front row on the right) and her sister Remmy Ma with engineers Suparna Mukherjee, Jaime Waydo and then Julie Towsend (back row).

The right Mast Camera (Mastcam) of NASA's Curiosity Mars rover provided this view of the lower stratigraphy at "Yellowknife Bay" inside Gale Crater on Mars.

This is an artist's concept showing a meteor shower in the skies above the Curiosity rover.

This image from NASA's Curiosity rover shows the great diversity of grains found on the surface of a Martian rock.

The rippled surface of the first Martian sand dune ever studied up close fills this Nov. 27, 2015, view of "High Dune" from the Mast Camera on NASA's Curiosity rover. This site is part of the "Bagn...

Holden Crater

This graph compares a typical daily pattern of changing atmospheric pressure (blue) with the pattern during a regional dust storm hundreds of miles away (red).

This image is from a test series used to characterize the 100-millimeter Mast Camera on NASA's Curiosity rover. It was taken on Aug. 23, 2012, and looks south-southwest from the rover's landing site.

This map shows the route driven by NASA's Curiosity Mars rover, from the location where it landed in August 2012 to its location in July 2017 (Sol 1750), and its planned path to additional geologic...

This graphic compares the radiation dose equivalent for several types of experiences, including a calculation for a trip from Earth to Mars based on measurements made by the Radiation Assessment De...

This pair of images from the Mast Camera (Mastcam) on NASA's Curiosity rover illustrates how special filters are used to scout terrain ahead for variations in the local bedrock.

The Curiosity rover mission to Mars is one of NASA's most complex and incredible successes. This 45-second trailer from the Jet Propulsion Laboratory takes you from designing and testing the rover ...
