Our Sun is nearing the most active part of its solar cycle. This week, we explore recent solar activity and discoveries from NASA's Parker Solar Probe with Nour Rawafi, the mission's project scientist. But first, we honor the life and legacy of Ed Stone, the former director of NASA's Jet Propulsion Laboratory and the longtime project scientist of the Voyager mission. We close out our show with Bruce Betts, the chief scientist of The Planetary Society, in What's Up.

Author, poet, and science communicator Diane Ackerman is our guest. Her wonderful collection of poems, with one devoted to each of the worlds in our Solar System, was first published in 1976. Carl Sagan said she had produced, “...a stunning book of poetry in The Planets. The work is scientifically accurate and even a convenient introduction to modern ideas on the planets, but much more important, it is spectacularly good poetry, clear, lyrical, and soaring. . . One of the triumphs of Ackerman’s pastoral is the demonstration of how closely compatible planetary exploration and poetry, science and art really are.” “The Planets” is now available in a brand new edition, and is as sublime, entertaining, and enlightening as it was half a century ago.

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.
