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.
Mastcam Telephoto of a Martian Dune's Downwind Face
Combining multiple images, NASA's Curiosity Mars rover reveals fine details of the downwind face of 'Namib Dune.' Sand on this face of the dark dune has cascaded down a slope of about 26 to 28 degrees.
Downwind Side of 'Namib' Sand Dune on Mars, Stereo
This stereo view from NASA's Curiosity Mars Rover, taken on Dec. 17, 2015, shows the downwind side of a dune about 13 feet high within the Bagnold Dunes on Mars. You need 3-D glasses to view this image.
Slip Face on Downwind Side of 'Namib' Sand Dune on Mars
This view from NASA's Curiosity Mars Rover, taken on Dec. 17, 2015, shows the downwind side of a dune about 13 feet high within the Bagnold Dunes field on Mars. As on Earth, the downwind side of an active sand dune has a steep slope called a slip face.
This graph shows the ratio of concentrations of several elements in four different pairs of targets examined by Alpha Particle X-ray Spectrometer (APXS) instruments on NASA Mars rovers Curiosity and Spirit.
Silicon and Titanium Correlation in Selected Rocks at Gale Crater, Mars
The yellow triangles on this graph indicate concentrations of the elements titanium and silicon in selected rock targets with high silica content analyzed by the APXS instrument on NASA's Curiosity rover in Mars' Gale Crater.
'Big Sky' and 'Greenhorn' Drilling Area on Mount Sharp
This view from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover covers an area in 'Bridger Basin' that includes the locations where the rover drilled a target called 'Big Sky' on the mission's Sol 1119 (Sept. 29, 2015).
This image from NASA's Curiosity Mars rover reveals details of a bedrock discoloration pattern at a site between 'Marias Pass' and 'Bridger Basin.' The discoloration is not associated with individual layers.
This view from NASA's Curiosity Mars rover shows an example of discoloration closely linked to fractures in the Stimson formation sandstone on lower Mount Sharp. The pattern is evident along two perpendicular fractures.
