Mars rovers safe lightning strikes
2021/3/5
If experiments done in small bottles in a University of Oregon lab are accurate, the friction of colliding Martian dust particles is unlikely to generate big electrical storms or threaten newly arrive...
New constraints on shergottite petrogenesis from analysis of Pb isotopic compositional space: Implications for mantle heterogeneity and crustal assimilation on Mars
shergottite Pb isotopes Martian geochemistry crustal assimilation mantle heterogeneity
2017/4/10
Geochemical studies of shergottites (Martian basalts) based on Rb-Sr, Sm-Nd, and Lu-Hf isotopic systematics have
provided clues to understanding the geochemical evolution of the Martian mantle and id...
Growth and form of the mound in Gale Crater, Mars: Slope wind enhanced erosion and transport
Growth and form of the mound Gale Crater Mars Slope wind enhanced erosion transport
2014/4/8
Ancient sediments provide archives of climate and habitability on Mars. Gale Crater, the landing site for the Mars Science Laboratory (MSL), hosts a 5-km-high sedimentary mound (Mount Sharp/Aeolis Mon...
WERE AQUEOUS RIPPLES ON MARS FORMED BY FLOWING BRINES?
Mars, brines ripples high viscosity bed forms
2014/4/8
The discovery in 2004 by Mars exploration rover Opportunity of sedimentary rocks with centimeter-scale trough cross-bedding is one of the compelling lines of evidence for flowing water on the Martian ...
Enhanced runout and erosion by overland flow at low pressure and sub-freezing conditions: Experiments and application to Mars
Mars, Surface Geological processes Experimental techniques
2014/4/8
We present the results of laboratory experiments to study the sediment transport and erosional capacity of water at current martian temperature and pressure. We have performed laboratory simulation ex...
Evidence for paleolakes in Erythraea Fossa, Mars: Implications for an ancient hydrological cycle
Mars Mars, Surface Mars, Climate Geological processes
2014/4/8
There is now widespread agreement that the surface of Mars underwent some degree of fluvial modification,but there is not yet full understanding of its surface hydrological cycle and the nature of sta...
Measurements of the Magnetism of the Mars-96 Small Station at the Nurmijärvi Geophysical Observatory
Martian magnetic field magnetic cleanliness planetary exploration
2009/6/10
Two US spacecraft are presently exploring Mars, and several scientific Martian missions are
planned for the next years. The Martian magnetic field is of great interest in many respects, and so magnet...
Localized gravity/topography admittance and correlation spectra on Mars: Implications for regional and global evolution
Localized gravity topography admittance correlation spectra on Mars Implications for regional global evolution
2014/4/9
From gravity and topography data collected by the Mars Global Surveyor spacecraft we calculate gravity/topography admittances and correlations in the spectral domain and compare them to those predicte...
