A Year of Saturn Discoveries From Cassini

The Giant Magellan Telescope (GMT) is poised to become one of the most powerful ground-based observatories ever built. On June 12, 2025, the U.S. National Science Foundation announced that the GMT will enter its Major Facilities Final Design Phase, bringing it one step closer to full construction. This week on Planetary Radio, host Sarah Al-Ahmed speaks with Rebecca Bernstein, Chief Scientist for the Giant Magellan Telescope Organization and astronomer at the Carnegie Institution for Science, about the groundbreaking technology behind GMT and how it will transform our understanding of the Cosmos.

Later in the show, Casey Dreier, chief of space policy at The Planetary Society, returns to discuss his new op-ed in Space News on the White House’s controversial Mars plan, and why a bold vision without political consensus is unlikely to succeed.

As always, we wrap up with What’s Up with Bruce Betts, chief scientist at The Planetary Society.

Few writers have captured the wonder of science through storytelling as powerfully as Dava Sobel. In this episode, we celebrate her remarkable career and her recent honor as the recipient of The Planetary Society’s 2025 Cosmos Award for Outstanding Public Presentation of Science. Mat Kaplan, senior communications advisor at The Planetary Society, sits down with Sobel for a conversation about the human lives behind great scientific discoveries, from Galileo and Copernicus to the women of the Harvard Observatory and Marie Curie’s lab. 

Later in the show, Jack Kiraly, our director of government relations, joins us with an encouraging update on our public advocacy campaign to save NASA science. And don’t miss What’s Up with Bruce Betts, where we reflect on the role of science communicators and share a fresh Random Space Fact.
