NASA's Europa Clipper mission is almost ready for its historic trip to the Jovian system. Merc Boyan, a visual storyteller at The Planetary Society, takes us into the clean room at NASA's Jet Propulsion Laboratory to speak with team members about the spacecraft. Then Bob Pappalardo, project scientist for Europa Clipper, visits The Planetary Society headquarters in Pasadena, CA, to share the story of the mission's vault plate, humanity's next collection of messages to another world. Bruce Betts, the Planetary Society chief scientist, closes out this week's show in What's Up, discussing his favorite messages from Earth.

On April 8, 2024, a total solar eclipse passed over Mexico, the United States, and Canada. This week on Planetary Radio, we take a trip to The Planetary Society’s Eclipse-O-Rama festival in Fredericksburg, Texas, where hundreds gathered to witness totality. We share the reactions of festival attendees along with snippets from the talks given by special guests at the event, including Bill Nye, the CEO of The Planetary Society, Bethany Ehlmann, president of The Planetary Society and principal investigator for the NASA Lunar Trailblazer mission, and Bee Hayes-Thakore, Vice President of Marketing at Kigen and member of The Planetary Society's board of directors. Tim Dodd, better known as the Everyday Astronaut, and Bob Pflugfelder, popularly known as Science Bob, share their experiences. Bruce Betts, the chief scientist of The Planetary Society, tells us about the solar features people may have seen during the eclipse in What's Up. Then we get an update on the Mars Sample Return mission with Casey Dreier, The Planetary Society's chief of space policy, and Jack Kiraly, our director of government relations.

Eclipse-O-Rama

This week on Planetary Radio, we explore "The Lost Universe," NASA's first tabletop role-playing game, with Christina Mitchell, a senior multimedia specialist at NASA's Goddard Space Flight Center in Maryland, U.S.A. Then, we'll shift our gaze from the mythical to the methodical with Amaury Triaud, an astronomer from the University of Birmingham in the U.K. He and his colleagues have found a new method for potentially detecting liquid water on the surfaces of terrestrial exoplanets. We close out with our chief scientist, Bruce Betts, for What's Up and a new random space fact.
