Back to MSFC Planetary Dr. Caleb Fassett

Dr. Caleb Fassett is a planetary scientist at NASA’s Marshall Space Flight Center. Originally from Maryland, Dr. Fassett earned his BS from Williams College in 2002, and MS and PhD from Brown University in 2005 and 2008, respectively.

His scientific research focuses on using a combination of remote sensing, geologic mapping, and numerical modeling to better understand planetary surfaces and geomorphological processes. He is also interested in how observations of impact crater populations can be used to infer the chronology and geologic history of planetary bodies.  He is currently a member of the VIPER, VERITAS, and KPLO science teams.


Dr. Fassett joined the planetary science group at Marshall Space Flight Center in 2016, after 5 years teaching at Mount Holyoke College. In addition to science, Dr. Fassett supports Center activities, including the Human Landing System program. Along with colleagues, Dr. Fassett works with these engineering teams to promote and advocate for science as NASA ventures deeper into our solar system.
