Space Policy Edition: How NASA remembers—and forgets
No one person knows how to build a spaceship. Dr. Janet Vertesi has seen this firsthand. She’s spent years embedded in NASA science teams, not as a participant, but as an observer. She’s a sociologist who studies the team dynamics of NASA missions. She is alarmed at the prospect of indiscriminate firings at the agency, and at the potential loss of institutional knowledge that won’t easily be rebuilt.

From backyard telescopes to global reach: AstroKobi and the power of short-form space videos
How does someone go from stargazing in a rural Australian backyard to inspiring millions around the world about space science? This week, Sarah Al-Ahmed sits down with Kobi Brown, better known as AstroKobi, to explore how his passion for the Cosmos and a knack for short-form storytelling launched his science communication career. They discuss the evolution of space outreach in the digital age, the power of social media to ignite curiosity, and how a new generation of space communicators is reshaping the way we connect with the Universe. You'll also hear the latest space policy update from Jack Kiraly, director of government relations at The Planetary Society, including developments affecting NASA’s science programs and the confirmation process for a new NASA administrator. We close out the show with What’s Up with Bruce Betts, chief scientist of The Planetary Society, and a discussion of direct imaging of exoplanets.

Passback budget breakdown: A 47% cut to NASA science
NASA’s science programs are facing the largest proposed budget cut in more than 40 years. This staggering 47%reduction could cancel missions, waste billions in U.S. taxpayer investments, and unravel decades of discovery. In this episode of Planetary Radio, host Sarah Al-Ahmed is joined by Casey Dreier, The Planetary Society’s Chief of Space Policy, and Jack Kiraly, Director of Government Relations. Together, they break down what the “passback” stage of the federal budget process means for NASA, which missions and programs are in jeopardy, and how you can help push back. Later in the show, Chief Scientist Bruce Betts joins us for a reflective What’s Up as we explore the science that could be lost and why it still deserves to be saved.

Why is Mars red? A new clue to the history of habitability in Martian dust
For decades, scientists hypothesized that Mars’ reddish color came from hematite, an iron oxide thought to have formed through dry oxidation after Mars lost its water. But new research suggests the story is more complex—and more watery—than we once imagined. In this episode, planetary scientist Adomas (Adam) Valantinas from Brown University joins host Sarah Al-Ahmed to discuss his team’s discovery that Mars’ iconic red dust is likely dominated not by hematite but by a hydrated mineral called ferrihydrite. This subtle but significant shift in understanding could reshape what we know about Mars’ climate history and its potential for past habitability. Then, Sarah and Bruce Betts, Planetary Society chief scientist, revisit one of the most famous Martian discoveries: Opportunity’s hematite-rich “blueberries,” which also told a compelling story about water on the Red Planet.
