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).
Curiosity View Ahead Through 'Artist's Drive' (Stereo)
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." 3-D glasses are need to view this image.
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.
Night Close-up of Mineral Veins at 'Garden City,' Mars
This view from the Mars Hand Lens Imager on the arm of NASA's Curiosity Mars rover is a close-up of a two-tone mineral vein at a site called 'Garden City' on lower Mount Sharp. It was taken during night, illuminated by LEDs, on March 25, 2015.
From afar, Saturn's rings look like a solid, homogenous disk of material. But upon closer examination from NASA's Cassini spacecraft, we see that there are varied structures in the rings at almost every scale imaginable.
