Evolution of Water Reservoirs on Mars: Constraints from Hydrogen Isotopes in Martian Meteorites
, 2014 Martian surface morphology implies that Mars was once warm enough to maintain persistent liquid water on its surface. While the high D/H ratios (~6 times the Earth's ocean water) of the current martian atmosphere suggest that significant water has been ...

Time and Length Scales of the Martian Atmospheric Turbulence as Observed by the InSight Lander
Geophysical Research LettersWe provide a statistical analysis of the Martian near‐surface atmospheric turbulence based on in situ wind observations from NASA's InSight lander. We focus on the variations in length and time scales of the Martian atmospheric turbulence caused by the ...

Morphology of Antarctic Polygons and Implications for Polygon Evolution and Subsurface Ice Dynamics
Permafrost and Periglacial Processes, Volume 37, Issue 1, Page 143-153, January/March 2026.ABSTRACT Polygonal terrain results from thermal contraction, is commonly found in periglacial environments, and serves as a valuable proxy for interpreting subsurface ice distribution and climate history on Earth and Mars. In this study, we investigate the morphology of polygons in Beacon Valley, Antarctica, to assess the relationship between polygon ...

Martian sub-surface ionising radiation: biosignatures and geology [PDF]
Biogeosciences, 2007 The surface of Mars, unshielded by thick atmosphere or global magnetic field, is exposed to high levels of cosmic radiation. This ionising radiation field is deleterious to the survival of dormant cells or spores and the persistence of molecular ...

Earth and Space Science, Volume 13, Issue 1, January 2026.Abstract Oxychlorines (i.e., perchlorates (ClO4−) and chlorates (ClO3−)) have been detected by several landed missions on Mars at various locations. These missions have provided crucial information about the geographic distribution and abundances of oxychlorines on Mars but have not definitively identified the cation and anion type of in situ, solid ...
