Jarosite and Hematite at Meridiani Planum from Opportunity's Mössbauer Spectrometer
Mössbauer spectra measured by the Opportunity rover revealed four mineralogical components in Meridiani Planum at Eagle crater: jarosite- and hematite-rich outcrop, hematite-rich soil,Expand
Alpha Particle X‐Ray Spectrometer (APXS): Results from Gusev crater and calibration report
[1] The chemical composition of rocks and soils on Mars analyzed during the Mars Exploration Rover Spirit Mission was determined by X-ray analyses with the Alpha Particle X-Ray Spectrometer (APXS).Expand
Detection of Silica-Rich Deposits on Mars
Mineral deposits on the martian surface can elucidate ancient environmental conditions on the planet. Opaline silica deposits (as much as 91 weight percent SiO2) have been found in association withExpand
Chemistry and mineralogy of outcrops at Meridiani Planum
Analyses of outcrops created by the impact craters Endurance, Fram and Eagle reveal the broad lateral continuity of chemical sediments at the Meridiani Planum exploration site on Mars. ApproximatelyExpand
Chemistry of Rocks and Soils at Meridiani Planum from the Alpha Particle X-ray Spectrometer
The Alpha Particle X-ray Spectrometer on the Opportunity rover determined major and minor elements of soils and rocks in Meridiani Planum. Chemical compositions differentiate between basaltic rocks,Expand
The Opportunity Rover's Athena Science Investigation at Meridiani Planum, Mars
The Mars Exploration Rover Opportunity has investigated the landing site in Eagle crater and the nearby plains within Meridiani Planum. The soils consist of fine-grained basaltic sand and a surfaceExpand
Chemistry of Rocks and Soils in Gusev Crater from the Alpha Particle X-ray Spectrometer
The alpha particle x-ray spectrometer on the Spirit rover determined major and minor elements of soils and rocks in Gusev crater in order to unravel the crustal evolution of planet Mars. TheExpand
The new Athena alpha particle X‐ray spectrometer for the Mars Exploration Rovers
[1] The new alpha particle X-ray spectrometer (APXS) is part of the Athena payload of the two Mars Exploration Rovers (MER). The APXS sensor head is attached to the turret of the instrumentExpand
Mineralogy of a Mudstone at Yellowknife Bay, Gale Crater, Mars
Sedimentary rocks at Yellowknife Bay (Gale crater) on Mars include mudstone sampled by the Curiosity rover. The samples, John Klein and Cumberland, contain detrital basaltic minerals, calciumExpand
Provenance and diagenesis of the evaporite-bearing Burns formation, Meridiani Planum, Mars
Abstract Impure reworked evaporitic sandstones, preserved on Meridiani Planum, Mars, are mixtures of roughly equal amounts of altered siliciclastic debris, of basaltic provenance (40 ± 10% by mass),Expand
