Planetary Radio brings you the human adventure across our Solar System and beyond. We visit each week with the scientists, engineers, leaders, advocates, and astronauts who are taking us across the final frontier. Regular features raise your space IQ while they put a smile on your face. Join host Sarah Al-Ahmed and Planetary Society colleagues including Bill Nye the Science Guy and Bruce Betts as they dive deep into space science and exploration. The monthly Space Policy Edition takes you inside the DC beltway where the future of the US space program hangs in the balance. Visit planetary.org/radio for an episode guide and much more.

Some of the most exciting science in our Solar System is hidden in places we've never been able to reach. In this episode, Sarah Al-Ahmed shares three conversations from the 2026 NASA Innovative Advanced Concepts (NIAC)Symposium at Wichita State University, all about the bold, early-stage concepts being developed to explore them.

First, Peter Cabauy, CEO and co-founder of City Labs Incorporated, and Mason Peck, former NASA Chief Technologist and collaborator on the project, discuss their Phase II concept, Autonomous Tritium Micropowered Sensors, tiny nuclear-powered probes designed to survive and operate in the permanently shadowed craters of the Moon and beyond. Then, Daniel Drew, assistant professor of electrical and computer engineering at the University of Hawaiʻi at Mānoa, introduces SPARK, a Phase I concept for silent, solid-state flying robots that could explore caves on Saturn's moon Titan. Finally, Gilly Elor, physics lead at Stone Aerospace, and Bill Stone, founder of Stone Aerospace, walk us through LUX, the Lunar Underground Explorer, a Phase I concept for a laser-powered, fiber-tethered drone that could be the first mission to enter a cave on another world. Plus, Bruce Betts, chief scientist of The Planetary Society, joins Sarah for What's Up, where they preview Saturn at opposition and the start of World Space Week on October 4th.

Researchers at the 2026 NIAC Symposium share their bold concepts for exploring the most inaccessible places in our Solar System, from the Moon's permanently shadowed craters to caves on Titan and inside lunar lava tubes.

JAXA's Hayabusa2 flew within 400 meters (1,300 feet) of asteroid Torifune on July 5 and confirmed that it's a contact binary, two lobes stuck together. Paul Abell, NASA's Chief Scientist for Small Body Exploration at Johnson Space Center, walks us through the findings on the asteroid, what they mean for planetary defense, and what's ahead as the spacecraft cruises toward its next target. Then Bruce Betts, chief scientist at The Planetary Society, digs into Hayabusa2's history of firing things at asteroids.

Where are we most likely to find evidence of life, past or living, in the Solar System? Planetary scientist and author Kevin Hand looks to warm, salty ocean depths beneath protective layers of ice on worlds such as Europa and Enceladus. His enthralling book became a popular selection in The Planetary Society’s member book club. He recently joined the Society’s Mat Kaplan for a deep exploration of the best science. Kevin also shared tales of his own harrowing, revealing journeys through Earth’s undersea world.
