Bethany Ehlmann

Bethany Ehlmann joined The Planetary Society’s Board of Directors in 2018. She is the director of the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado, Boulder, and a university faculty member. She previously served as a professor of planetary science at Caltech and a research scientist at NASA’s Jet Propulsion Laboratory. In 2018, she published the children’s book Dr. E’s Super Stellar Solar System with National Geographic.

Bethany’s research focuses on the mineralogy and chemistry of planetary surfaces, remote sensing techniques and instruments, astrobiology, and science policy and outreach. She is principal investigator of the NASA Lunar Trailblazer small satellite mission to map water on the Moon. She is co-investigator on the upcoming EMIT mission, a space station-based imaging spectrometer to explore Earth's dust source regions, the Europa Clipper mission, and is working to propose mission concepts for ocean worlds, Venus, and asteroids. Much of her other recent scientific work has focused on unraveling Mars' environmental history: she is a member of the science teams for the Mars Exploration Rovers (Spirit and Opportunity), the CRISM imaging spectrometer on the Mars Reconnaissance Orbiter, the Mars Science Laboratory (Curiosity) rover, and the Mars 2020 rover (Perseverance). She was also an affiliate of the Dawn orbiter team during its exploration of Ceres. She is co-investigator on the upcoming EMIT mission, a space station-based imaging spectrometer to explore dust source regions, and is working to propose mission concepts for ocean worlds, Venus, and asteroids.

Bethany is active in the space policy arena, having served as a member of the National Academies Committee on Astrobiology and Planetary Science. She was also vice-chair of the Mars panel and a member of the Steering Committee for the National Academies Decadal Survey for Planetary Sciences and Astrobiology 2023-2032. She has also served on the science policy committees of presidential candidates.

Bethany is a 2013 National Geographic Emerging Explorer, a former Mineralogical Society of America Distinguished Lecturer, a recipient of the American Geophysical Union’s Macelwane medal, the American Astronomical Society Planetary Science Division Urey prize, and COSPAR’s Zeldovich medal, as well as NASA Group Achievement Awards. Previously, she was a European Union Marie Curie Fellow at the Institut d’Astrophysique Spatiale, Orsay, France.

Originally from Tallahassee, FL, she earned her Ph.D. and master’s in geological sciences as a National Science Foundation graduate fellow at Brown University, earned masters degrees from the University of Oxford in Environmental Change and Management and Geography as a Rhodes Scholar, and received her undergraduate degree from Washington University in St. Louis.

When not exploring the planets, Bethany can be found hiking, playing tennis, surfing (or trying to), scuba diving, enjoying the amazing food and wine culture of southern California and beyond (an activity that pairs well with the more athletic pursuits), and native plant gardening.
