Seminar Abstract:

Mechanical properties of martian regolith are important to understand since they affect various geophysical processes such as slope stability and wind erosion. The nature of cohesive bonds is also affected by the hydrologic cycle and aqueous geochemistry. Thus, mechanical properties serve as a window to modern martian climate processes. In this talk I will explain the laboratory work we have done to quantify the effect of water and/or salt on the cohesion and angle of internal friction of simulated martian regolith. These geophysical processes have implications for the success of current and future Mars rovers, and I will also talk about methods to identify these salts from orbit using new lab spectroscopy.
