Since 2002, Planetary Radio has visited with a scientist, engineer, project manager, advocate, or writer who provides a unique perspective on the quest for knowledge about our Solar System and beyond. The full show archive is available for free.
Lujendra Ojha, assistant professor at Rutgers University, joins Planetary Radio to discuss how subsurface liquid water on exoplanets orbiting red dwarf stars could increase the likelihood of finding habitable worlds beyond our Solar System.
Mario Jurić and Ari Heinze from the University of Washington join Planetary Radio to discuss their team’s next-generation asteroid discovery algorithm, HelioLinc3D.
Kevin Trinh from Arizona State University joins Planetary Radio to discuss his research into Europa's formation history and the consequences for the moon's habitability.
Amy Williams, assistant professor of geology at the University of Florida, joins Planetary Radio to discuss the proposed Mars Life Explorer mission and the search for extant life on Mars.
Matt Siegler from the Planetary Science Institute shares his team's surprising findings about the granite formation that might lie beneath Compton-Belkovich, a thorium-rich hot spot on the far side of the Moon.
Chris Glein, a lead scientist at the Southwest Research Institute, joins Planetary Radio to talk about the discovery of phosphorus in the oceans of Saturn’s moon Enceladus and the implications for the search for life.
Caltech and Brown University’s Jay Dickson joins Planetary Radio to discuss the mysterious formation of gullies on Mars.
Sam Birch, an assistant professor at Brown University, explores what we know about the alluvial rivers of Earth, Mars, and Saturn's moon Titan.
We check in on the congressional budget process for NASA, Mars Sample Return’s spiraling cost growth, and the impending end of the regulatory holiday for human commercial space launch companies.
Planetary Radio, Mat Kaplan, senior communications adviser at The Planetary Society, takes us to the 2023 Humans to Mars Summit in Washington, D.C. We'll share his conversation with three NASA Associate Administrators, Nicola Fox, James Free, and James Reuter about the international, commercial, and robotic collaboration it will take to put the first humans on the Red Planet.
James Drake from the University of Maryland joins Planetary Radio to talk about the latest results from NASA's Parker Solar Probe as it soars closer to our star than any spacecraft in history.
Richard Durisen and Paul Estrada join Planetary Radio to discuss their research on the surprisingly recent formation of Saturn's rings and why they are disappearing over time.
Justin Spilker joins Planetary Radio to talk about his team’s detection of the oldest organic molecules in the known Universe.
Sarafina El-Badry Nance joins Planetary Radio to discuss her new book, Starstruck: A Memoir of Astrophysics and Finding Light in the Dark.
Shubham Kanodia, the lead on a paper about a so-called forbidden planet, TOI 5202 b, joins us to talk about this strange world and why it's upending our understanding of planetary formation.
Darby Dyar, Deputy Principal Investigator for NASA's VERITAS mission to Venus, joins Planetary Radio to share the human story behind the spacecraft and make a case for saving the mission.
Join us as we celebrate the successful launch of the European Space Agency's Juice mission with project scientist Olivier Witasse.
Phil Plait, the Bad Astronomer, joins Planetary Radio to discuss his new book, Under Alien Skies: A Sightseer’s Guide to the Galaxy.
Join us as we celebrate the accomplishments of a truly inspiring space mission - the United Arab Emirates' Hope probe, which has spent two amazing years orbiting Mars!
Robbie Herrick and Scott Hensley, the minds behind a new paper on recent potential volcanic activity on Venus, join Planetary Radio to discuss their discovery and what it means for the future of Venusian exploration.
