Planetary Radio Episodes
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.
Astrophysicist, former astronaut and NASA associate administrator John Grunsfeld on human exploration of space and the science we will do there.
Join us for a tour of the University of Arizona’s Mirror Lab where they use a giant, spinning oven filled with molten glass to create the primary mirrors for the Giant Magellan Telescope.
Cassini Mission Project Scientist Linda Spilker has now taken on the same job for the Voyager Interstellar Mission.
Celebrate Carl Sagan’s birthday with his longtime collaborator and life partner Ann Druyan.
The Double Asteroid Redirection Test was a brilliant success. The leaders of NASA’s Planetary Defense Coordination Office tell us what’s next in the quest to protect Earth.
Meet leaders of two of the most successful Earth-based searches for asteroids, including many that could threaten Earth.
Join us at the 2022 NASA Innovative Advanced Concepts (NIAC) Symposium for a taste of projects that just might change the world.
How will nations react if (when?) humanity detects the presence of an alien intelligence or civilization? That’s the topic Planetary Society Chief Advocate Casey Dreier takes up with his guest, astrophysicist Jason Wright.
Director of SOFIA Science Mission Operations Margaret Meixner joins us to lament the end of the giant flying observatory and to celebrate its tremendous successes.
Listen as the Double Asteroid Redirection Test spacecraft closes in on asteroid Dimorphos, followed by a triumphant conversation with DART Coordination Lead Nancy Chabot, and a visit with space image processor Judy Schmidt.
The DART spacecraft’s impact on asteroid moonlet Dimorphos is days away, so we’ll check in with Mission Coordination Lead Nancy Chabot as well as Simone Pirrotta, program manager for the LICIACube probe that will be watching the smackdown.
It’s a party for Voyager and the team of scientists, engineers and others who have followed it across our Solar System. Then we’ll visit with Ann Druyan, creative director for the Voyager Golden Record.
Getting precious Mars rocks into Earthbound labs is an unprecedented challenge. We'll learn how a lander, a rocket, a big solar-powered transfer vehicle and two helicopters will take on this task.
Scientists have found a menagerie of complex organic compounds on the comet visited by the Rosetta spacecraft that connect it with the birth of our solar system.
The former director of NASA’s Planetary Science division, Jim Green, retired as the agency’s chief scientist in January. This episode opens with a special announcement from host Mat Kaplan.
NASA and its partners have revealed the first stunning images from the new space telescope. We’ll talk about them with Bill Nye and members of the JWST team.
Lori Garver went up against powerful forces inside and outside NASA to create the hugely successful commercial cargo and crew programs.
Space exploration historian Michael Neufeld traces the fascinating history of one of NASA’s most successful programs of planetary exploration.
We Earthlings are making progress toward defending our planet from near-Earth objects, which is reason enough for the annual Asteroid Day celebration.
Celebrate the third anniversary of LightSail 2’s launch with Bill Nye and other leaders of The Planetary Society.
