    Dr. Barbara Cohen is a planetary scientist at NASA Goddard Space Flight Center. Originally from upstate New York, Dr. Cohen earned her BS in Geology from the State University of New York at Stony Brook and her PhD in Planetary Science from the University of Arizona. Her main scientific interests are in geochronology and geochemistry of planetary samples from the Moon, Mars and asteroids. She is a Principal Investigator on multiple NASA research projects, a member of the science teams operating the Mars rovers Opportunity and Curiosity, and the principal investigator for Lunar Flashlight, a lunar cubesat mission that will be launched in 2019 as an SLS secondary payload. She is the PI for the Mid-Atlantic Noble Gas Research Laboratory (MNGRL) and is developing a flight version of her noble-gas geochronology technique, the Potassium-Argon Laser Experiment (KArLE), for use on future planetary landers and rovers. She has participated in the Antarctic Search for Meteorites (ANSMET) in four seasons, where she helped recovered more than a thousand pristine samples for the US collection. Asteroid 6816 Barbcohen is named for her.

    Brief Bio

    Dr. Barbara Cohen is a planetary scientist at NASA Goddard Space Flight Center. Originally from upstate New York, Dr. Cohen earned her BS in Geology from the State University of New York at Stony Brook and her PhD in Planetary Science from the University of Arizona. Her main scientific interests are in geochronology and geochemistry of planetary samples from the Moon, Mars and asteroids. She is a Principal Investigator on multiple NASA research projects, a member of the science teams operating the Mars rovers Opportunity and Curiosity, and the principal investigator for Lunar Flashlight, a lunar cubesat mission that will be launched in 2019 as an SLS secondary payload. She is the PI for the Mid-Atlantic Noble Gas Research Laboratory (MNGRL) and is developing a flight version of her noble-gas geochronology technique, the Potassium-Argon Laser Experiment (KArLE), for use on future planetary landers and rovers. She has participated in the Antarctic Search for Meteorites (ANSMET) in four seasons, where she helped recovered more than a thousand pristine samples for the US collection. Asteroid 6816 Barbcohen is named for her.
