Planetary Analogs in Antarctica: Mars

Abstract

A study of chemical and physical weathering rates in Antarctic ice-free areas, sponsored by the National Science Foundation's Antarctic Research Program, permitted observations to be made that also have application other planetary surfaces. Four observations relevent to Mars are addressed: the effects of freezing on sand dune morphology (Mars polar dune field), chemical/physical weathering to create pits (Mars pitted rocks, Viking Lander 1 and 2 sites), armored surfaces (Mars lander sites), and mass movements (movement of Martian debris).
