Sean Solomon on the Climactic End of the MESSENGER Mission to Mercury

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.

 TOI-270 d: Unveiling the secrets of a sub-Neptune

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.

Space Policy Edition: How NASA remembers—and forgets

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.
