Abigail Fraeman

Abigail Fraeman is broadly interested in the origin and evolution of terrestrial bodies in our solar system, and her work has concentrated on investigating how the complex geologic histories of Mars and its moons are preserved in their rock record.  She specialized in remote sensing with a focus on visible and short wavelength infrared reflectance spectroscopy.  Abigail received a PhD in Earth & Planetary Sciences from Washington University in St Louis and a BS in Physics and in Geology & Geophysics and  Yale University.

  • Ph.D., Earth and Planetary Sciences, Washington University in St. Louis, 2014
  • A.M., Earth and Planetary Sciences, Washington University in St Louis, 2011
  • B.S., Geology & Geophysics, Physics, Yale University, 2009

Research Interests

History and evolution of Mars, Phobos and Deimos, Reflectance spectroscopy from the macro- to micro-scale.


MRO - Mars Reconnaissance Orbiter Icon MRO - Mars Reconnaissance Orbiter
NASA's Mars Reconnaissance Orbiter (MRO) launched in 2005 and is on a search for evidence that water persisted on the surface of Mars for a long period of time.

MER - Mars Exploration Rovers Icon MER - Mars Exploration Rovers
NASA's twin robot geologists, the Mars Exploration Rovers, launched toward Mars on June 10 and July 7, 2003, in search of answers about the history of water on Mars.

MSL - Mars Science Laboratory Icon MSL - Mars Science Laboratory

The Curiosity rover landed at Gale Crater on August 5, 2012. It is designed to search for and assess past or present habitable environments, i.e., those capable of supporting microbial life.
