ILLUMINATION INVARIANT CHANGE DETECTION (IICD): FROM EARTH TO MARS
Illumination Planetary Surface Change Detection Phase Correlatio Saliency Active Contour
2018/5/15
Multi-temporal Earth Observation and Mars orbital imagery data with frequent repeat coverage provide great capability for planetary surface change detection. When comparing two images taken at differe...
TARGET TRANSFORMATION CONSTRAINED SPARSE UNMIXING (TTCSU) ALGORITHM FOR RETRIEVING HYDROUS MINERALS ON MARS: APPLICATION TO SOUTHWEST MELAS CHASMA
Prior information Sparse unmixing Hydrous minerals Mars CRISM
2018/5/15
Quantitative analysis of hydrated minerals from hyperspectral remote sensing data is fundamental for understanding Martian geologic process. Because of the difficulties for selecting endmembers from h...
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...
Interactive evolution of multiple water-ice reservoirs on Mars: Insights from hydrogen isotope compositions
Mars water ice isotope atmospheric escape
2017/4/10
Remote sensing data from orbiter missions have proposed that ground ice may currently exist on Mars, although the
volume is still uncertain. Recent analyses of Martian meteorites have suggested that ...
Crater clusters on Mars:Shedding light on martian ejecta launch conditions
Cratering Mars Meteorites Impact processes
2015/12/25
We have identified two classes of crater clusters on Mars. One class is “small clusters” (crater diameter D ～ tens m, spread over few hundred m), fitting our earlier calculations for the breakup of we...
Ice Keel Scour Marks on Mars:Evidence for Floating and Grounding Ice Floes in Kasei Valles

Analysis of enigmatic structures on Mars and Venus and implications for crustal history
The earth's crust planets utopia plain terrain Mars crater wrinkles ridge
2014/10/22
The crustal history of two structurally complex areas on two different planetary bodies is explored, using a combination of image and topographic analysis, kinematic mapping and numerical modeling. Th...
Significance of Water-Related Features on Mars
Cydonia Mensae Isidis Planitia Mars Pitted cones putative shorelines Utopia Planitia
2014/10/22
The debate on whether water exists on Mars has been resolved by recent data from the Mars Phoenix Polar Lander. The lander found water ice just below the surface in the high northern latitudes of Mars...
