Eclipse-O-Rama

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.

Tabletops and telescopes: NASA’s RPG and the hunt for habitable worlds

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.

Radiolab helps name a quasi-moon of Venus

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.

Space Policy Edition: Real and Acceptable Reasons for Space Exploration

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?

Syzygy science: Discoveries made during total solar eclipses

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.

Geothermal activity on the icy dwarf planets Eris and Makemake

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. The lead author of this research, Chris Glein, joins Planetary Radio to explain. But our journey doesn't stop there. We dive into the newly reformed US Planetary Science Caucus with The Planetary Society's top space policy experts, Casey Dreier and Jack Kiraly. Our senior communications adviser, Mat Kaplan, celebrates a monumental achievement in space exploration — the successful landing of Intuitive Machine's Odysseus spacecraft on the lunar surface. And don't miss the latest installment of What's Up with Bruce Betts, our chief scientist, as he shares a new random space fact.

Space Policy Edition: The ahistorical era of commercial lunar exploration

The successful landing of IM-1 on the Moon ushered in a new era of commercial lunar exploration, one that has little to no historical precedent. The future, still highly uncertain, is rich with promise for what commercial payload deliveries can provide. There will be new and more frequent science opportunities, lower-cost access for national and non-state actors, and, potentially, a path to a sustainable presence on the lunar surface. Dr. Matt Shindell, science historian and curator of the planetary exploration collection at the Smithsonian Institution, joins the show to discuss the unique historical moment we find ourselves in, and how planetary exploration has evolved and could continue to evolve on and around the Moon.

The legacy of Red Rover Goes to Mars

Over two decades ago, an innovative partnership between The Planetary Society, NASA, and LEGO created the Red Rover Goes to Mars program. Today, we reflect on the program's remarkable achievements with our chief scientist, Bruce Betts. We're also joined by two extraordinary people whose lives were forever changed by their experiences as student astronauts in the program during their high school years. Courtney Dressing, an associate professor in the Department of Astronomy at the University of California, Berkeley, and Abigail Fraeman, the deputy project scientist for NASA's Curiosity Rover at the Jet Propulsion Laboratory, share their inspiring journeys through the program and beyond. Then Bruce Betts returns to share more of LEGO's involvement in space exploration and a new random space fact.
