107 presentations delivered through the NASA Jet Propulsion Laboratory Solar System Ambassador program between 2018 and August 2026, for schools, libraries, retirement communities, civic groups, and the Laurel Springs School Astronomy Club.
I set each topic with whoever requested the talk and then build the presentation from NASA's published material, which is the only source the ambassador program permits.
