Extensive evidence of landform-scale martian geomorphic changes has been acquired in
the last decade, and the number and range of examples of surface activity have increased …

Abstract The High-Resolution Imaging Camera (HiRIC) is one major payload of China's first
Mars exploration mission, and its main objective is to obtain the detailed observation images …

A committee of the Mars Exploration Program Analysis Group (MEPAG) has reviewed and
updated the description of Special Regions on Mars as places where terrestrial organisms …

Water probably flowed across ancient Mars, but whether it ever exists as a liquid on the
surface today remains debatable. Recurring slope lineae (RSL) are narrow (0.5 to 5 meters) …

Orbital observations suggest that Mars underwent a recent 'ice age'(roughly 0.4–2.1 million
years ago), during which a latitude-dependent ice-dust mantle (LDM), was emplaced. A …

Granular materials avalanche when a static angle of repose is exceeded and freeze at a
dynamic angle of repose. Such avalanches occur subaerially on steep hillslopes and wind …

Liquid water is a basic ingredient for life as we know it. Therefore, in order to understand the
habitability of other planets we must first understand the behavior of water on them. Mars is …

Recurring Slope Lineae (RSL) are small scale seasonal flow features identified by Mars
Reconnaissance Orbiter that present several interesting characteristics such as an albedo …

Recent studies of martian dune and non-dune gullies have suggested a seasonal control on
present-day gully activity. The timing of current gully activity, especially activity involving the …

Despite radically different environmental conditions, terrestrial and martian dunes bear a
strong resemblance, indicating that the basic processes of saltation and grainfall (sand …
