  • Mineralogical composition of sands in Meridiani Planum

    [1] Constraints on the mineralogical composition of low‐albedo, low‐sulfur sands at Meridiani Planum are determined from Mars Exploration Rover (MER) Opportunity Miniature Thermal Emission Spectrometer (Mini‐TES), Mössbauer, and Alpha Proton X–Ray Spectrometer measurements. Results of this work show that the sand is olivine basaltic in composition, with minor amounts of sulfate and a

  • Morphology, stratigraphy, and mineralogical composition

    This is suggested by the mineralogical composition of LDs that is consistent with low water-to-rock ratios (Milliken et al., 2008), and by the sinuous ridges that are interpreted as inverted channels rather than as eskers. Episodical precipitation in regions of LDs may have alimented a substrate enriched in ice. Global events (e.g., obliquity changes) or local events (e.g., impacts, volcanic

    Rosalind Franklin, previously known as the ExoMars rover, is a planned robotic Mars rover, part of the international ExoMars programme led by the European Space Agency and the Russian Roscosmos State Corporation.. Scheduled to launch in July 2020, the plan calls for a Russian launch vehicle, an ESA carrier module, and a Russian lander named Kazachok, that will deploy the rover to Mars' surface.

  • Geology of Mars Wikipedia

    The geology of Mars is the scientific study of the surface, crust, and interior of the planet Mars.It emphasizes the composition, structure, history, and physical processes that shape the planet. It is analogous to the field of terrestrial geology.In planetary science, the term geology is used in its broadest sense to mean the study of the solid parts of planets and moons.

  • Jarosite and Hematite at Meridiani Planum from

    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). Spherules, interpreted to be concretions, are hematite-rich and dispersed throughout the outcrop.

    The mineralogical composition of Río Tinto sediments (cf. next section) reflects the physical and stone conditions of ambient waters. In contrast, both macroscopic and microscopic features of sediment texture are influenced by the Río Tinto biota. Laminated domal structures along the present day river margin resemble stromatolites, but can be interpreted without recourse to microbial

  • Río Tinto: A Geochemical and Mineralogical Terrestrial

    Río Tinto as a geochemical and mineralogical terrestrial Mars analogue provides an interesting perspective for the interpretation of Martian data for two reasons. First, both iron oxides and ferric sulfates are generated at Río Tinto under well-characterized physico-chemical and biological conditions 20,36,48,50]. Second, the modern drainage, where depositional processes can be observed in
