 Current Primary Research
  • NASA: "Equilibrium Shapes of Solid Solar System Bodies"
    • What shapes can solar system bodies take on if they are soils or rocks?
    • How fast can they spin without disruption?
    • What is the required strength?
    • When will tidal forces break them apart?

  • NASA : "Models and Code Calculation of Impact Processes in Asteroids and Solar System Bodies"
    • What analytical models of material behavior are needed for impacts into soils and rocks?
    • What features of the model affect what features of the results?
    • How do different models in the community compare in outcomes?
    • What actual data is available for calibration?
    • Compare calculations using newly developed models to the field data and other code results
