What does it take to turn a love of space into a global career in science journalism? Sarah Cruddas has done just that. With a background in astrophysics and a passion for storytelling, she’s become a leading voice in space media, covering rocket launches, interviewing astronauts, and writing books that bring the Cosmos down to Earth. In this episode, Sarah shares her path from the U.K. to the front lines of space communication and why she believes storytelling is essential to the future of exploration. She also reflects on the challenges of breaking into the field, the power of listening, and how space can unite people across the globe. Plus, Bruce Betts joins us for What’s Up, where we talk about what makes a great space journalist.

Former NASA Chief Economist Akhil Rao explains why NASA needs economic expertise to navigate the complex—and often misunderstood—market forces that will determine the success or failure of its private partnerships. As NASA relies ever more on commercial companies to enable its own exploration efforts, it is imperative, Rao believes, to provide clear-eyed perspectives that highlight the challenges and solutions required to reach success. And why NASA puts itself at risk for pursuing faith-based program investments after dissolving the strategy and economics team at the agency a few months ago.

The White House has released its Fiscal Year 2026 congressional budget justification for NASA, and the implications are staggering. If enacted, this proposal would slash NASA’s science program funding by nearly half, cancel dozens of active and upcoming missions, and reduce the agency’s workforce by one-third. Sarah Al-Ahmed is joined by Jack Kiraly, The Planetary Society’s director of government relations, to examine what’s in the nearly 500-page document, what it means for the future of space science and exploration, and how advocates can still act to save NASA science.

Then, in What’s Up, Planetary Society Chief Scientist Bruce Betts shares insights on China’s newly launched asteroid sample return mission, Tianwen-2. The spacecraft will rendezvous with near-Earth asteroid 469219 Kamoʻoalewa, offering new scientific opportunities amidst a moment of global uncertainty in space exploration.

Volcanoes aren’t just an earthly phenomenon. They’re found all across the Solar System. In this compilation episode of Planetary Radio, we explore volcanic and geothermal activity on planets, moons, and distant dwarf planets. You’ll hear from Rosaly Lopes, Nick Schneider, Rae Paoletta, Robbie Herrick, Scott Hensley, and Christopher Glein as they share insights into everything from lava flows on Venus and eruptions on Io to the mysterious heat signatures of icy bodies like Eris and Makemake. This journey spans over 20 years of Planetary Radio, featuring interviews hosted by both current host Sarah Al-Ahmed and founding host Mat Kaplan.

Then, our Chief Scientist, Dr. Bruce Betts, returns for What’s Up and shares new findings from NASA’s Juno mission, which recently completed close passes by Jupiter’s volcanic moon, Io.

As debates over NASA's future heat up, questions about the value of space exploration are popping up everywhere. This week on Planetary Radio, we're tackling the tough questions head-on with The Planetary Society's staff, including Casey Dreier, chief of space policy, and Ambre Trujillo, digital community manager. They break down the biggest misconceptions about space science, public versus private investment, and why exploration still matters in an ever-changing world.

Then Jack Kiraly, director of government relations, joins us for a space policy update. We discuss the growing movement to save NASA science, how community action is ramping up, and what’s happening behind the scenes on Capitol Hill.

And in What's Up with Bruce Betts, we explore some of the most recent NASA spinoffs, technologies developed for space that are making life better here on Earth.

This week on Planetary Radio, we explore the decades-long journey of Kosmos 482, a Soviet-era Venus probe that spent 53 years orbiting Earth before its dramatic return on May 10, 2025. Ben Fernando, a postdoctoral researcher in seismology and planetary science at Johns Hopkins University, joins us to explain the history of Kosmos 482 and how seismology and acoustic sensors are helping scientists detect and locate objects impacting Earth. Then Bruce Betts, our chief scientist, joins us for What's Up, where we look back at the largest human-made objects ever to crash back to Earth.

TOI-270 d is revealing secrets about the most common type of planet in our galaxy, sub-Neptunes. Sarah Al-Ahmed is joined by planetary geochemist Chris Glein from the Southwest Research Insitute to discuss his team’s new analysis of its atmosphere, using data from JWST and insights from Earth analogs. Then, The Planetary Society’s Director of Government Relations, Jack Kiraly, breaks down the historic budget cuts proposed for NASA in the U.S. President’s “skinny” budget request, including a 47% reduction to its science program funding. We close out with Bruce Betts and What’s Up.

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.
