Remote Sensing
Overview
We use planetary data from satellites, rovers, and aerial instruments to assess surface processes and geologic history. These data sets help us understand the chemical, thermophysical, and topographic properties of the planet's surface.
Projects
Hypanis sediment fan deposit
We investigated whether this feature was a mudflow, alluvial fan, or delta deposit from remote sensing data. Bedding dip angles, thermal inertia, morphology, and other properties were measured and results are reported.
