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.

Making space matter: A space journalist’s journey

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.
