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
Mars Science Laboratory Mission and Science Investigation
AbstractScheduled to land in August of 2012, the Mars Science Laboratory (MSL) Mission was initiated to explore the habitability of Mars. This includes both modern environments as well as ancientExpand
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
TLDR
Opaline silica deposits found on Mars are interpreted to have formed under hydrothermal conditions and therefore to be strong indicators of a former aqueous environment, important for understanding the past habitability of Mars. Expand
A Habitable Fluvio-Lacustrine Environment at Yellowknife Bay, Gale Crater, Mars
The Curiosity rover discovered fine-grained sedimentary rocks, which are inferred to represent an ancient lake and preserve evidence of an environment that would have been suited to support a martianExpand
Chemistry of Rocks and Soils at Meridiani Planum from the Alpha Particle X-ray Spectrometer
TLDR
The Alpha Particle X-ray Spectrometer on the Opportunity rover determined major and minor elements of soils and rocks in Meridiani Planum, indicating the interaction with water in the past is indicated by the chemical features in rocks and soils. Expand
Mars methane detection and variability at Gale crater
TLDR
Curiosity confirms the presence and variability of atmospheric methane, implying episodic production from an unknown source, and reports of plumes or patches of methane in the martian atmosphere that vary over monthly time scales have defied explanation. Expand
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 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
