Global Mineralogical and Aqueous Mars History Derived from OMEGA/Mars Express Data
Global mineralogical mapping of Mars by the Observatoire pour la Mineralogie, l'Eau, les Glaces et l'Activité (OMEGA) instrument on the European Space Agency's Mars Express spacecraft provides newExpand
Volcanic Outgassing of CO2 and H2O on Mars
Abstract Volcanic outgassing is one of the main sources of volatiles for the martian atmosphere and degassing of the martian interior potentially influenced the early martian climate. Using aExpand
Recent and episodic volcanic and glacial activity on Mars revealed by the High Resolution Stereo Camera
It is shown that calderas on five major volcanoes on Mars have undergone repeated activation and resurfacing during the last 20 per cent of martian history, with phases of activity as young as two million years, suggesting that the volcanoes are potentially still active today. Expand
Sequence of infilling events in Gale Crater, Mars: Results from morphology, stratigraphy, and mineralogy
Gale Crater is filled by sedimentary deposits including a mound of layered deposits, Aeolis Mons. Using orbital data, we mapped the crater infillings and measured their geometry to determine theirExpand
Deposition and degradation of a volatile-rich layer in Utopia Planitia, and implications for climate history on Mars.
[1] We investigate the surface morphology of a study area in western Utopia Planitia, Mars, which is characterized by a variety of landforms that resemble those of terrestrial periglacial landscapes.Expand
Tropical to mid-latitude snow and ice accumulation, flow and glaciation on Mars
Images from the Mars Express HRSC (High-Resolution Stereo Camera) of debris aprons at the base of massifs in eastern Hellas reveal numerous concentrically ridged lobate and pitted features andExpand
The topography and morphology of low shields and associated landforms of plains volcanism in the Tharsis region of Mars
Abstract The morphology and topography of volcanic landforms provide critical information to the investigation of their tectonic setting and the physical characteristics (e.g., rheology) of theirExpand
The high-resolution stereo camera (HRSC) experiment on Mars Express: Instrument aspects and experiment conduct from interplanetary cruise through the nominal mission
ESA's Mars Express has successfully completed its nominal mission of one Martian year covering about 25% of the surface in stereo and color with resolutions up to 10 m/pixel by its high-resolutionExpand
Working models for spatial distribution and level of Mars' seismicity
[1] We present synthetic catalogs of Mars quakes, intended to be used for performance assessments of future seismic networks on the planet. We have compiled a new inventory of compressional andExpand
Evolution and depositional environments of the Eberswalde fan delta, Mars
The Eberswalde crater and its contributing basins have been analyzed in detail in order to reconstruct the geological evolution of the water-related landforms with particular focus on the EberswaldeExpand
