Mineral Content Comparison at Two Gale Crater Sites
This graphic shows proportions of minerals identified in mudstone exposures at the 'Yellowknife Bay' location where NASA's Curiosity Mars rover first analyzed bedrock, in 2013, and at the 'Murray Buttes' area investigated in 2016.
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.
Signature of Hematite in 'Confidence Hills' Martian Rock
This side-by-side comparison shows the X-ray diffraction patterns of two different samples collected from rocks on Mars by NASA's Curiosity rover. The images present data obtained by Curiosity's Chemistry and Mineralogy instrument (CheMin).
These images, made from data obtained by Curiosity's CheMin, show the patterns obtained from a drift of windblown dust and sand called 'Rocknest' and from a powdered rock sample drilled from the 'John Klein' bedrock.
This graphic shows results of the first analysis of Martian soil by the CheMin experiment on NASA's Curiosity rover. The image reveals the presence of crystalline feldspar, pyroxenes and olivine mixed with some amorphous (non-crystalline) material.
