Replicating Martian Dunes

This engineering drawing shows the location of the arm on NASA's Curiosity rover, in addition to the arm's turret, which holds two instruments and three tools.

The gray area in the center of this image is where the Dust Removal Tool on the robotic arm of NASA's Mars rover Curiosity brushed a rock target called "Wernecke."

This map shows the route on lower Mount Sharp that NASA's Curiosity followed between April 19, 2015, and Nov. 5, 2015. During this period the mission investigated silica-rich rock targets includin...

A rock fragment dubbed "Lamoose" is shown in this picture taken by the Mars Hand Lens Imager (MAHLI) on NASA's Curiosity rover.

No bones about it! Seen by Mars rover Curiosity using its MastCam, this Mars rock may look like a femur thigh bone. Mission science team members think its shape is likely sculpted by erosion, eithe...

Scientists have now named the four marks near NASA's Curiosity rover where blasts from the descent stage rocket engines blew away some of the Martian surface material.

The dual sections of the Atlas V payload fairing for NASA's Mars Science Laboratory (MSL) mission await further processing in the airlock of the Payload Hazardous Servicing Facility at NASA's Kenne...

This stereo view from the Navigation Camera (Navcam) on NASA's Curiosity Mars rover shows the terrain ahead of the rover as it makes its way westward through a valley called "Artist's Drive." The i...

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

This image maps the traverse of NASA's Mars rover Curiosity from "Bradbury Landing" to "Yellowknife Bay," with an inset documenting a change in the ground's thermal properties with arrival at a dif...

This map shows all the quadrant themes for NASA’s Curiosity Mars rover, which is currently in the Roraima quadrant seen at the bottom. The red oval indicates the landing ellipse where the rover was...

Like a human working in a radiation environment, NASA's Curiosity rover carries its own version of a dosimeter to measure radiation from outer space and the sun.

This view of a Martian rock called "Rocknest 3" combines four images taken by the right-eye camera of the Mast Camera (Mastcam) instrument, which has a telephoto, 100-millimeter-focal-length lens.

The first stage of the Atlas V rocket for NASA's Mars Science Laboratory (MSL) mission arrives at the Vertical Integration Facility at Space Launch Complex 41 on Cape Canaveral Air Force Station.

The hole that NASA's Curiosity Mars rover drilled into target rock "John Klein" provided a view into the interior of the rock, as well as obtaining a sample of powdered material from the rock.

NASA’s Curiosity captured this 360-degree panorama while parked below Gediz Vallis Ridge (seen at right), a formation that preserves a record of one of the last wet periods seen on this part of Mar...

This graphic tracks the maximum relative humidity and the temperature at which that maximum occurred each Martian day, or sol, for about one-fourth of a Martian year, as measured by the Remote Envi...

This image is an artist's concept of the Mars Science Laboratory on the surface of Mars.

This panorama of the landscape surrounding NASA's Curiosity Mars rover on July 31, 2014, offers a view into sandy lower terrain called "Hidden Valley," which is on the planned route ahead.

This color panorama shows a 360-degree view of the landing site of NASA's Curiosity rover, including the highest part of Mount Sharp visible to the rover. That part of Mount Sharp is approximately ...

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.

The two main parts of the ChemCam laser instrument for NASA's Mars Science Laboratory mission are shown in this combined image.
