From Earth to the Edge of the Universe: A New Edition of “The Cosmos”

Join Sarah Al-Ahmed and Casey Dreier for a special live recording of Planetary Radio at the Johns Hopkins University Bloomberg Center in Washington, D.C., immediately following The Planetary Society’s Day of Action. In this episode, we explore the complex geopolitical landscape NASA faces as it works toward returning humans to the Moon and exploring other worlds. With growing influence from commercial space companies, potential budget cuts, and changes in committee leadership, this pivotal moment in space exploration is shaping NASA’s future.

We’re joined by Bill Nye (CEO, The Planetary Society), Nancy Chabot (Chief Scientist, Johns Hopkins Applied Physics Laboratory), Rep. George Whitesides (Representative, CA-27), Rep. Judy Chu (Co-chair, Congressional Planetary Science Caucus, Representative, CA-28), and Antonio Peronace (Chief Executive, Space for Humanity). Together, we explore how evolving national priorities, key lawmakers, and the rapid growth of the commercial space sector could reshape U.S. space policy, potentially redefining the motivations that have driven space exploration since the Apollo era.

Live from Washington, D.C.: The future of space politics

The Apollo program put humans on the Moon, but behind that historic achievement were engineers whose stories have gone largely untold. In this episode, “LA Made: The Other Moonshot” host Joanne Higgins joins Planetary Radio to share the powerful history of Charlie Cheatham, Nate LeVert, and Shelby Jacobs, three Black engineers in Los Angeles who helped make Apollo possible while navigating racism and exclusion. We discuss how their technical brilliance shaped the space program, why their stories were left out of the history books, and how telling them now can help create a more equitable space community for the future.

Plus, Casey Dreier checks in from Washington, D.C., during The Planetary Society’s Day of Action, where advocates from across the U.S. gathered to support NASA science. And in What’s Up, Bruce Betts and Sarah explore the Apollo-era technologies still in use today.

The Other Moonshot: The untold stories of Apollo’s Black engineers in Los Angeles

We take you inside the Mars Innovation Workshop, hosted at the SETI Institute’s headquarters and produced by Explore Mars. Planetary Society Senior Communications Advisor Mat Kaplan shares highlights from the event, exploring how cross-disciplinary collaboration is shaping the future of Mars exploration and creating solutions for challenges here on Earth.

Meanwhile, major changes are happening at NASA. In a move that has raised concerns in the space community, NASA leadership has dissolved key advisory offices, including the Office of the Chief Scientist and the Office of Technology, Policy, and Strategy. Jack Kiraly, our director of government relations, explains what these cuts mean for the agency’s future and why space advocates should be paying attention.

Then Bruce Betts shares his favorite Mars innovations and a new Random Space Fact, in this week’s What’s Up!
