Geology before Pluto: Pre-encounter considerations - Jeff Moore (SETI Ta...

The
cameras of New Horizons will provide robust data sets that should be
imminently amenable to geological analysis of the Pluto system’s
landscapes. I will give with a brief discussion of the planned
observations by the New Horizons cameras that will bear most directly on
geological interpretability.
Then I will review the major
geological processes that could potentially operate on the surfaces of
Pluto and its major moon Charon. I will briefly survey exogenic
processes (i.e. those for which energy for surface modification is
supplied externally to the planetary surface): impact cratering,
sedimentary processes (including volatile migration), and the work of
wind. I will conclude with an assessment of the prospects for endogenic
activity in the form of tectonics and cryovolcanism.
