Robert Smith shares the story of how the astronomical community decided upon the JWST as the follow-up to the Hubble Space Telescope, the coalition politics required for mega-projects like Hubble and JWST, and how that dynamic shapes modern science. Dr. Smith holds a Ph.D. in the history and philosophy of science from the University of Cambridge. He  is a professor at the University of Alberta. His book, The Space Telescope: A Study of NASA, Science, Technology, and Politics, was released in 1989. Discover more here:https://www.planetary.org/planetary-radio/robert-smith-jwst-big-science

The Planetary Society's 2026 Day of Action brought something new this year. For the very first time, the advocacy day was followed by a showcase of NASA funded science in an event called Igniting Discovery.

Host Sarah Al-Ahmed speaks with Jack Kiraly, Director of Government Relations at the Planetary Society, about how the event came together, and with first-time advocate Julianna Charlene Kolczynski, whose passion for space traces back to her grandfather's dreams. Megan McKeown, Director of Governmental Affairs at the Association of Public and Land-Grant Universities, opens the event. Then we hear from the scientists themselves: Blake Schreurs of the Johns Hopkins Applied Physics Laboratory, planetary scientist Kirby Runyon of the Planetary Science Institute, Christine McCarthy of Columbia University's Lamont-Doherty Earth Observatory, Brent McBride of the University of Maryland Baltimore County, biomechanics PhD student Liliana Delgado of the University of Nebraska Omaha, and science communicator Sarah Treadwell, also known as Space Case Sarah. Planetary Society member Ari Gozlan closes with a reflection on what it means to celebrate science after the Day of Action. Plus, Chief Scientist Bruce Betts joins Sarah for What's Up.

For the first time, the Planetary Society's annual Day of Action was followed by Igniting Discovery, a showcase of the NASA-funded science we're fighting to protect, held in the US Senate building. 

Igniting Discovery: A showcase of NASA-funded research

Every year, members of The Planetary Society travel to Washington, D.C., to make their voices heard on Capitol Hill. This year, just days after the Artemis II crew splashed down off the coast of San Diego, the Presidential Budget Request dropped once more, proposing a 46% cut to NASA's science budget. 

Planetary Radio host Sarah Al-Ahmed was on the ground capturing the passion, the preparation, and the people behind one of the largest Days of Action in the Planetary Society's history. In this episode, we hear from Bill Nye, Planetary Society chief ambassador. Sarah speaks with Planetary Society CEO Jenn Vaughn, charter members and advocates David Johnson and Philip Shane, healthcare researcher and human factors scientist Gabe Segarra, astrobiologist and postdoctoral fellow at Carnegie Science Earth & Planets Laboratory Michael Wong, and Colossus Computing CEO Jason Cerundolo and CTO Alex Swehla.

Plus, Chief Scientist Bruce Betts joins us for What's Up, where we discuss the missions at stake if NASA's science budget is cut.

The fight to save NASA science is back. Planetary Radio host Sarah Al-Ahmed takes you to Washington, D.C., for the 2026 Day of Action, where Planetary Society members, scientists, and advocates hit Capitol Hill to oppose a proposed 46% cut to NASA's science budget.

Day of Action 2026: Rejoining the fight to save NASA science

When Artemis II returned its crew safely to Earth, millions of people found themselves unexpectedly moved. The mission was a test flight, a proof-of-concept, and yet it felt like something far greater than the sum of its parts.

In this episode, Casey Dreier, chief of space policy at The Planetary Society, sits down with Rebecca Lowe, philosophy senior fellow at the Mercatus Center at George Mason University, to explore the deeper meaning of humanity's return to deep space. Drawing on philosophy of mind, aesthetics, and theories of value, they unpack why human presence in space feels fundamentally different from even the most sophisticated robotic mission, and why that difference matters.
