Clay Mineral Crystal Structure Tied to Composition
This diagram illustrates how the dimensions of clay minerals' crystal structure are affected by which ions are present in the composition of the mineral. Different clay minerals were identified this way at two sites, 'Yellowknife Bay' and 'Murray Buttes'
Detecting a Difference in Clay Minerals at Two Gale Crater Sites
Data graphed here from the CheMin instrument on NASA's Mars Curiosity rover show a difference between clay minerals in powder drilled from mudstone outcrops at two locations, 'Yellowknife Bay' and 'Murray Buttes' in Mars' Gale Crater.
Mudstone Mineralogy from Curiosity's CheMin, 2013 to 2016
This series of pie charts shows similarities and differences in the mineral compositions of mudstones at 10 sites where NASA's Curiosity Mars rover collected rock-powder samples and analyzed them with the rover's Chemistry and Mineralogy instrument.
Late 2016 Map of NASA's Curiosity Mars Rover Mission
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 December 2016, which is in the upper half of a geological unit called the Murray formation, on lower Mount Sharp.
Opportunity View of 'Private Joseph Field' on Mars
This image of a target called 'Private Joseph Field' combines four images from the microscopic imager on the robotic arm of NASA's Mars Exploration Rover Opportunity, with enhanced color information added from the rover's panoramic camera.
Opportunity Inspects 'Gasconade' on 'Spirit Mound' of Mars
This mosaic combines four frames taken by the microscopic imager on NASA's Opportunity's robotic arm on Oct. 2, 2016 showing relatively bright outcropping of rock, dubbed 'Gasconade' on the western edge of Mars' Endeavour Crater.
This image from NASA's Mars Reconnaissance Orbiter shows one of these exotic locales at the South Pole. The polar cap is made from carbon dioxide (dry ice). The circular pits are holes in this dry ice layer that expand by a few meters each Martian year.
Martian Terrain Near Curiosity's 'Precipice' Target
This Dec. 2, 2016, view from the Navcam on the mast of NASA's Curiosity Mars Rover shows rocky ground within view while the rover was working at an intended drilling site called 'Precipice' on lower Mount Sharp.
A NASA radio aboard ESA's Trace Gas Orbiter, succeeded in its first test of receiving data transmitted from NASA Mars rovers. This graphic depicts the geometry of Opportunity transmitting data to the orbiter, using the UHF band of radio wavelengths.
This image captured by NASA's 2001 Mars Odyssey spacecraft shows a small portion of Noctis Labyrinthus. Noctis Labyrinthus is a network of tectonic graben and collapse valleys on the western margin of Valles Marineris.
