New results from high-resolution imaging has shown a range of active
surface processes on Mars: gully incision and deposition at
dozens of locations, especially in dunes; more than 200 new impact
events, some exposing shallow ice; avalanches off the edges of the
north polar ice cap; migration of aeolian ripples and shifting sand
deposits; slope streaks; dust devils; rock falls; and a bizarre suite
of activities associated with seasonal and perennial CO2. Of special
interest are implications for environmental change with orbital
variations (i.e., what can happen today vs. what required different
conditions). Also of special interest is the question of whether
liquid water or brines are involved in any of these current processes.
