Breccia-Conglomerate Rocks on Lower Mount Sharp, Mars (Stereo)
The rock in the foreground at right in this 3D scene is informally named 'Balombo.' The group of boulders is at a site called 'Bimbe.' NASA's Curiosity Mars Rover shows boulders composed of pebble-size and larger rock fragments.
Curiosity's Arm Over 'Marimba' Target on Mount Sharp
NASA's Curiosity Mars rover began close-up investigation of a target called 'Marimba,' on lower Mount Sharp, during the week preceding the fourth anniversary of the mission's dramatic sky-crane landing.
Two Sizes of Ripples on Surface of Martian Sand Dune
Two sizes of wind-sculpted ripples are evident in this view from NASA's Curiosity of the top surface of 'Namib Dune' in the Bagnold Dune Field. The larger ripples are a type not seen on Earth nor previously recognized as a distinct type on Mars.
This observation from NASA's Mars Reconnaissance Orbiter spacecraft is of Noctis Labyrinthus, a highly tectonized region immediately to the west of Valles Marineris. It formed when Mars' crust stretched itself apart.
The giant sand dunes in Kaiser Crater, seen by NASA's Mars Reconnaissance Orbiter, experience gully erosion of the steep slip faces every year in late winter as the sun warms these slopes and seasonal carbon dioxide frost sublimates.
The dunes shown here, as seen by NASA's Mars Reconnaissance Orbiter spacecraft, form distinct dots and dashes. The 'dashes' are linear dunes formed by bi-directional winds, which are not traveling parallel to the dune.
Seasonal Cycles in Curiosity's First Two Martian Years
By monitoring weather throughout two Martian years since landing in Gale Crater in 2012, NASA's Curiosity Mars rover has documented seasonal patterns such as shown in these graphs of temperature, water-vapor content and air pressure.
Northern Portion of Gale Crater Rim Viewed from 'Naukluft Plateau'
This early-morning view from NASA's Curiosity Mars rover covers a field of view of about 130 degrees of the inner wall of Gale Crater. The rover's location was on the "Naukluft Plateau" of lower Mount Sharp.
This mid-afternoon, 360-degree panorama was acquired by NASA's Curiosity Mars rover on April 4, 2016, as part of long-term campaign to document the context and details of the geology and landforms along Curiosity's traverse inside Gale Crater.
Nodules of Cemented Sand Grains Within Martian Sandstone
This view from NASA's Curiosity shows nodules exposed in sandstone that is part of the Stimson geological unit on Mount Sharp, Mars. The nodules can be seen to consist of grains of sand cemented together.
Patches of Martian sandstone visible in this view from NASA's Curiosity Mars rover have a knobbly texture due to nodules apparently more resistant to erosion than the host rock in which some are still embedded.
New Waypoint, Science Team Newcomers for Curiosity
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 early March 2016, approaching a geological waypoint called Naukluft Plateau.
The Mars Hand Lens Imager (MAHLI) camera on the robotic arm of NASA's Curiosity Mars rover used electric lights at night to illuminate this view of Martian sand grains dumped on the ground after sorting with a sieve.
This self-portrait of NASA's Curiosity Mars rover shows the vehicle at 'Namib Dune,' where the rover's activities included scuffing into the dune with a wheel and scooping samples of sand for laboratory analysis.
This view from NASA's Curiosity rover of the downwind face of 'Namib Dune' on Mars covers 360 degrees, including a portion of Mount Sharp on the horizon. The site is part of the dark-sand 'Bagnold Dunes' field along the northwestern flank of Mount Sharp.
