Göstar Klingelhöfer,R. V. Morris,B. Bernhardt,Christian Schröder,Daniel Rodionov,P. A. de Souza,Albert S. Yen,Ralf Gellert,E. N. Evlanov,B. Zubkov,J. Foh,J. Foh,Uwe Bonnes,E. Kankeleit,Philipp Gütlich,D. W. Ming,Franz Renz,Thomas J. Wdowiak,Steven W. Squyres,Raymond E. Arvidson +19 more
TL;DR: 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, olivine-bearing basaltic soil, and a pyroxene-bearing Basaltic rock (Bounce rock).

TL;DR: The analysis of the data from the Phoenix mission revealed an alkaline environment, in contrast to that found by the Mars Exploration Rovers, indicating that many different environments have existed on Mars.

Mössbauer mineralogy of rock, soil, and dust at Gusev crater, Mars: Spirit's journey through weakly altered olivine basalt on the plains and pervasively altered basalt in the Columbia Hills
R. V. Morris,Göstar Klingelhöfer,Christian Schröder,Daniel Rodionov,Albert S. Yen,D. W. Ming,P. A. de Souza,Iris Fleischer,Thomas J. Wdowiak,R. Gellert,B. Bernhardt,E. N. Evlanov,B. Zubkov,J. Foh,J.

TL;DR: The Moessbauer spectrometer on Spirit measured the oxidation state of Fe, identified Fe-bearing phases, and measured relative abundances of Fe among those phases for surface materials on the plains and in the Columbia Hills of Gusev crater as discussed by the authors.
Evidence for Calcium Carbonate at the Mars Phoenix Landing Site
William V. Boynton,D. W. Ming,Samuel P. Kounaves,S. M. M. Young,Raymond E. Arvidson,Michael H. Hecht,John H. Hoffman,Paul B. Niles,D. K. Hamara,Richard C. Quinn,Peter H. Smith,Brad Sutter,David C. Catling,David C. Catling,R. V. Morris +14 more
TL;DR: Results suggest that the soil at the Phoenix landing site must have suffered alteration through the action of liquid water in geologically the recent past, and an alkaline environment was revealed, in contrast to that found by the Mars Exploration Rovers, indicating that many different environments have existed on Mars.

TL;DR: In this paper, the first three drilled samples from the Murray formation, measured in the Pahrump Hills section, were reported, along with full pattern fitting analyses of X-ray diffraction patterns measured by the MSL CheMin instrument.
