Present-Day Landscape Evolution on Mars I Posters
Session ID#: 23844
Session Description:
Long-lived robotic missions have documented many active surface processes on Mars, including slope, impact, aeolian, and polar processes. These data are now producing insights into landscape evolution over longer timescales. Examples include formation of complex gullied slopes, carbon-dioxide-driven erosion of south polar terrains (including “spiders”), dune field evolution and implications for erosion of layered sediments, steep polar scarps with seasonal avalanches, and new impact events causing dust avalanches. Of special interest due to the possible role of water are recurring slope lineae (RSL), with characteristic associated morphologies such as small gullies or channels, sandy fans, and slumps. There are also better constraints on the rates of other processes, such as ice sublimation and glacial flow in the middle latitudes and tectonic activity. Rovers and landers provide important in situ measurements supporting orbital monitoring. We invite submissions documenting active surface change or assessing current landscape evolution on longer timescales.
