An image taken at the 'Hidden Valley' site, en-route to Mount Sharp, by NASA's Curiosity rover. A variety of mudstone strata in the area indicate a lakebed deposit, with river- and stream-related deposits nearby.
A view from the 'Kimberly' formation on Mars taken by NASA's Curiosity rover. The strata in the foreground dip towards the base of Mount Sharp, indicating the ancient depression that existed before the larger bulk of the mountain formed.
Vista from Curiosity Shows Crossbedded Martian Sandstone
Large-scale crossbedding in the sandstone of this ridge on a lower slope of Mars' Mount Sharp is typical of windblown sand dunes that have petrified. NASA's Curiosity Mars rover used its Mastcam to capture this vista on Aug. 27, 2015.
Test Rover at JPL During Preparation for Mars Rover's Low-Angle Selfie
This view of a test rover at NASA's Jet Propulsion Laboratory, Pasadena, California, results from advance testing of arm positions and camera pointings for taking a low-angle self-portrait of NASA's Curiosity Mars rover.
Curiosity Finds Hydrogen-Rich Area of Mars Subsurface
Curiosity's Russian-made instrument for checking hydration levels in the ground beneath the rover detected an unusually high amount at a site near 'Marias Pass,' prompting repeated passes over the area to map the hydrogen amounts.
Curiosity Low-Angle Self-Portrait at 'Buckskin' Drilling Site on Mount Sharp
This low-angle self-portrait of NASA's Curiosity Mars rover shows the vehicle above the 'Buckskin' rock target, where the mission collected its seventh drilled sample. The site is in the 'Marias Pass' area of lower Mount Sharp.
Round-Horizon Version of Curiosity's Low-Angle Selfie at 'Buckskin'
This version of a self-portrait of NASA's Curiosity Mars rover at a drilling site called 'Buckskin' on lower Mount Sharp is presented as a stereographic projection, which shows the horizon as a circle.
Hole at 'Buckskin' Drilled Days Before Landing Anniversary
NASA's Curiosity Mars Rover drilled this hole to collect sample material from a rock target called 'Buckskin' on July 30, 2015, during the 1060th Martian day, or sol, of the rover's work on Mars. The diameter is slightly smaller than a U.S. dime.
A rock outcrop dubbed 'Missoula,' near Marias Pass on Mars, is seen in this image mosaic taken by NASA's Curiosity rover. Pale mudstone (bottom of outcrop) meets coarser sandstone (top) in this geological contact zone.
A rock fragment dubbed 'Lamoose' is shown in this picture taken by NASA's Curiosity rover. Like other nearby rocks in a portion of the 'Marias Pass' area of Mt. Sharp, Mars, it has unusually high concentrations of silica.
Tracking Sunspots from Mars, April 2015 (Animation)
This single frame from a sequence of six images of an animation shows sunspots as viewed by NASA's Curiosity Mars rover from April 4 to April 15, 2015. From Mars, the rover was in position to see the opposite side of the sun.
Tracking Sunspots from Mars, Summer 2015 (Animation)
This single frame from a sequence of images shows sunspots as viewed by NASA's Curiosity Mars rover from June 27 to July 8, 2015; the rover was in position to see the opposite side of the sun from the side facing Earth during this period.
Rover's Reward for Climbing: Exposed Geological Contact
The Martian outcrop where pale rock meets darker overlying rock near the middle of this view from NASA's Curiosity Mars rover is an example of a geological contact. It was taken with the rover's Navcam on May 21, 2015.
Unfavorable Terrain for Crossing Near 'Logan Pass'
This view southeastward from NASA's Curiosity's Mastcam shows terrain judged difficult for traversing between the rover and an outcrop in the middle distance where a pale rock unit meets a darker rock unit above it.
This frame is from sequence of views NASA's Curiosity Mars rover recorded of the sun setting at the close of the mission's 956th Martian day, or sol (April 15, 2015), from the rover's location in Gale Crater.
This map shows the route on lower Mount Sharp that NASA's Curiosity followed in April and early May 2015, in the context of the surrounding terrain. Numbers along the route identify the sol, or Martian day, on which it completed the drive.
This April 16, 2015, panorama from the Mast Camera on NASA's Curiosity Mars rover shows a detailed view toward two areas, 'Mount Shields' and 'Logan Pass,' on lower Mount Sharp, chosen for close-up inspection in subsequent weeks.
A sweeping panorama combining 33 telephoto images into one Martian vista presents details of several types of terrain visible on Mount Sharp from a location along the route of NASA's Curiosity Mars rover.
NASA's Curiosity Mars rover used its Navigation Camera (Navcam) to capture this scene toward the west just after completing a drive that took the mission's total driving distance past 10 kilometers (6.214 miles).
