An Earth Analog to Mars' Yellowknife Bay
This set of images shows a modern terrestrial analog to the "Yellowknife Bay" area that NASA's Curiosity rover is exploring. At left is a sampling pit exposing clay-bearing lake sediments, deposited in a basaltic basin in southern Australia. At right is a core sample from the lakebed, showing clay-rich, layered sediments. Image released March 12, 2013.
Location of John Klein Drill Site
This false-color map shows the area within Gale Crater on Mars, where NASA's Curiosity rover landed on Aug. 5, 2012 PDT (Aug. 6, 2012 EDT) and the location where Curiosity collected its first drilled sample at the "John Klein" rock. Image released March 12, 2013.
Studying Habitability in Ancient Martian Environments
This set of images shows the results from the rock abrasion tool from NASA's Mars Exploration Rover Opportunity (left) and the drill from NASA's Curiosity rover (right). Note how the rock grindings from Opportunity are brownish red, indicating the presence of hematite, a strongly oxidized iron-bearing mineral. Image released March 12, 2013.
Major Gases Released from Drilled Samples of the "John Klein" Rock
An analysis of a drilled rock sample from NASA's Curiosity rover shows the presence of water, carbon dioxide, oxygen, sulfur dioxide, and hydrogen sulfide released on heating. The results analyzing the high temperature water release are consistent with smectite clay minerals. Image released March 12, 2013.
Chlorinated Forms of Methane at "John Klein" Site
NASA's Curiosity rover has detected the simple carbon-containing compounds chloro- and dichloromethane from the powdered rock sample extracted from the "John Klein" rock on Mars. These species were detected by the gas chromatograph mass spectrometer (GCMS) on Curiosity's Sample Analysis at Mars instrument (SAM). Image released March 12, 2013.
Curiosity Rover's Mars 'Hood Ornament' Photo
A shiny-looking Martian rock is visible in this image taken by NASA's Mars rover Curiosity's Mast Camera (Mastcam) during the mission's 173rd Martian day, or sol (Jan. 30, 2013). Read the full story.
Mars Rover Curiosity at Dingo Gap
This mosaic of images from the Navigation Camera (Navcam) on NASA's Mars rover Curiosity shows the terrain to the west from the rover's position on the 528th Martian day, or sol, of the mission (Jan. 30, 2014). [Read the Full Story Here]
Mast Camera and Its Calibration Target on Curiosity Rover
This set of images illustrates the twin cameras of the Mast Camera (Mastcam) instrument on NASA's Curiosity Mars rover (upper left), the Mastcam calibration target (lower center), and the locations of the cameras and target on the rover. Image released March 18, 2013.
Close-up of Martian 'Door Handle' Rock
A close-up of a shiny, wind-sculpted rock photographed by NASA's Mars rover Curiosity on Jan. 30, 2013. Read the full story.
Ventifacted Surface of Mars
Ventifacted (wind-eroded) Martian surface is caused by fine particles of dust and sand impacting the surface over time. Read the full story.
