Guest: Don HartsellIntroduction: In the upcoming months, we have not one, but two solar eclipses that are set to sweep across the continental United States: an annular eclipse on October 14 and a total solar eclipse on April 8, 2024. The eclipse in April will be the second total eclipse to cross the country in the past decade and the last until 2044. It will also serve as the final exclamation point on a month-long research expedition across the country aimed at collecting data on airborne microplastics aboard an airship as it travels from California to Texas. Joining us is one of the leaders of the expedition, Don Hartsell, to discuss the journey and what the group on board hopes to achieve.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
