Chloe Beddingfield is a planetary scientist at SETI and NASA Ames Research Center in Mountain View, CA.

Her research interests include the following:

  • Icy satellite tectonics, geodynamics, and geomorphology
  • Polygonal impact craters
  • Generating digital elevation models (DEMs) of all planetary surfaces and shape models of small bodies using stereo and photoclinometry

Research Interests:
I am interested in how the surfaces and interiors of icy and rocky planetary bodies formed and evolved. Planetary surfaces vary widely across the Solar System and often exhibit bizarre and unique features. I am particularly interested in investigating these surface features to gain insight into subsurface activity, structure, thermal properties, and the geologic histories of these planetary bodies. My research areas include geodynamics, tectonics, and geomorphology. I also derive surface topography as digital elevation models (DEMs) using stereo and photoclinometry to carry out my research.

NASA Missions:
OSIRIS-REx (Regolith Development Working Group)
New Horizons (Geology and Geophysics Imaging Team)
