The asteroid hunter

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.

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.

Sometimes, misunderstandings can spark beautiful adventures. This week on Planetary Radio, we explore the story behind the naming of Zoozve, a quasi-moon of Venus, with Latif Nasser, co-host of Radiolab. He shares how a typo on a space poster led the Radiolab team on an epic quest to convince the International Astronomical Union to name this quirky space object. Then, Bruce Betts, our chief scientist, pops in for What's Up and a discussion of some of the things asteroid hunters have found lurking in our Solar System.

Former NASA Administrator Mike Griffin joins the Space Policy Edition to discuss his notable 2007 speech outlining the tension between so-called “real” and “acceptable” reasons for space exploration. “Acceptable” reasons for space exploration are logical, policy-friendly justifications such as workforce development, technology spinoffs, and STEM engagement. They are quantifiable and dispassionate — the Vulcans of arguments. However, Griffin argues that the essence of humanity's drive to explore space is the “real” reasons, which are intuitive, emotional, and grand. They have value but are hard to quantify. These include the innate human desire for competitiveness, curiosity, and the urge to leave lasting legacies through monumental achievements.  Why do we have this dichotomy? What in the system itself prefers acceptable reasons over real reasons? And how can we leverage the relative strengths of both systems to be better space advocates?

Planetary Radio marks its last show before the Apr. 8 total solar eclipse with a look back at discoveries made during totality. Planetary Society science editor Asa Stahl shares why solar maximum is excellent for eclipse observing but potentially scary for Earth. Then Jeff Rich, outreach coordinator at the Carnegie Science Observatories in Pasadena, CA, joins Planetary Radio to discuss how total solar eclipses have contributed to our understanding of the Sun and beyond. Bruce Betts, our chief scientist, closes the show with What's Up and a chat about the ways that Einstein's general relativity impacts humanity and our technology.

On April 8, 2024, a total solar eclipse will sweep across North America. Ron Benner, the President of the American Optometric Association, joins Planetary Radio to share safety tips to protect your eyes during partiality. Then, astrophotographer Andrew McCarthy gives helpful advice about observing solar eclipses using telescopes and cameras. We close the show with our chief scientist, Bruce Betts, as he discusses The Planetary Society's new eclipse book for kids, "Casting Shadows," and the upcoming Eclipse-O-Rama festival in Texas, U.S.A.

The countdown is on! With less than a month until the total solar eclipse on April 8, 2024, Planetary Radio is buzzing with anticipation. This celestial event will sweep across Mexico, the United States, and Canada, promising a spectacular view to millions. Jim Bell, a professor from the School of Earth and Space Exploration at Arizona State University and former president of The Planetary Society's Board of Directors, will share captivating tales from his global eclipse-chasing journeys. But before diving into the cosmic wonders, we'll bring you the latest updates on the proposed US Presidential Budget. The Planetary Society's space policy experts, Casey Dreier and Jack Kiraly, will explain what this budget proposal means for NASA's funding and future projects. Then, the great Bruce Betts will pop in for What's Up as host Sarah Al-Ahmed looks forward to high-fiving him in person at The Planetary Society's upcoming Eclipse-O-Rama event in Texas, U.S. Discover more at: https://www.planetary.org/planetary-radio/2024-eclipse-chasingSee omnystudio.com/listener for privacy information.

A team co-led by the Southwest Research Institute has made a groundbreaking discovery, revealing evidence of hydrothermal or metamorphic activity on the icy dwarf planets Eris and Makemake in the Kuiper Belt.
