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.
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 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.
The Rover Environmental Monitoring Station (REMS) on NASA's Curiosity Mars rover includes temperature and humidity sensors mounted on the rover's mast. One of the REMS booms extends to the left from the mast in this view.
Cross-bedding seen in the layers of this Martian rock is evidence of movement of water recorded by the waves or ripples of loose sediment the water passed over, such as a current in a lake. This image is from NASA's Curiosity Mars rover.
This view from the NASA's Curiosity Mars rover shows an example of cross-bedding that results from water passing over a loose bed of sediment. It was taken at a target called 'Whale Rock' within the 'Pahrump Hills' outcrop at the base of Mount Sharp.
This image from NASA's Curiosity Mars rover shows an example of a thin-laminated, evenly stratified rock type that occurs in the 'Pahrump Hills' outcrop at the base of Mount Sharp on Mars. This type of rock can form under a lake.
This evenly layered rock photographed by the Mast Camera (Mastcam) on NASA's Curiosity Mars Rover on Aug. 7, 2014, shows a pattern typical of a lake-floor sedimentary deposit not far from where flowing water entered a lake.
Bedding Pattern Interpreted as Martian Delta Deposition
On March 25, 2014, view from the Mastcam on NASA's Curiosity Mars rover looks southward at the Kimberley waypoint. Multiple sandstone beds show systematic inclination to the south suggesting progressive build-out of delta sediments.
This image from Curiosity's Mastcam shows inclined beds of sandstone interpreted as the deposits of small deltas fed by rivers flowing down from the Gale Crater rim and building out into a lake where Mount Sharp is now.
Within Rover's Reach at Mars Target Area 'Alexander Hills'
This view from ASA's Curiosity Mars rover shows a swath of bedrock called 'Alexander Hills,' which the rover approached for close-up inspection of selected targets. It is a mosaic of six frames taken on Nov. 23, 2014.
Fine-Grained, Finely Layered Rock at Base of Martian Mount Sharp
This patch of Martian bedrock, about 2 feet (70 centimeters) across, is finely layered rock with some pea-size inclusions. It lies near the lowest point of the 'Pahrump Hills' outcrop, which forms part of the basal layer of Mount Sharp.
Erosion Resistance at 'Pink Cliffs' at Base of Martian Mount Sharp
This small ridge, about 3 feet long, appears to resist wind erosion more than the flatter plates around it. Such differences are among the traits NASA's Curiosity Mars rover is examining at selected rock targets at the base of Mount Sharp.
