Katie Mack and The End of Everything

This is part two of our Star Trek 60th anniversary series. Robert Picardo, the Emergency Medical Hologram on Star Trek: Voyager and a member of The Planetary Society's board of directors, reads a vintage letter from Star Trek creator Gene Roddenberry asking fans to join a brand new organization called The Planetary Society. Tim Russ, who played Tuvok on Star Trek: Voyager, Deep Space Nine, Lower Decks, and Picard, joins us to talk about what the Vulcans can teach us about the discipline we'll need to survive in deep space, and shares his own experience as an amateur astronomer who contributed data to NASA's Lucy mission. Karim Diané, Jay-Den Kraag on Star Trek: Starfleet Academy, talks about playing a Klingon who defies everyone's expectations of what it means to be strong. And Bruce Betts, chief scientist of The Planetary Society, is here with What's Up, discussing Star Trek technologies.

Star Trek at 60: What Vulcans and Klingons can teach us about being human (Part 2)

Star Trek turned 60 on Sept. 8, 2026, and to celebrate, we're kicking off a special two-part series exploring the franchise's deep and lasting connection to real-world space exploration. In Part 1, Robert Picardo, the Emergency Medical Hologram from Star Trek: Voyager, now starring in Star Trek: Starfleet Academy and a member of The Planetary Society's Board of Directors, joins Sarah Al-Ahmed to trace the relationship between Star Trek and The Planetary Society all the way back to a 1980 letter from Gene Roddenberry himself. Bob talks about how playing a holographic doctor for 30 years led him to become a real-world space advocate, and what Star Trek's non-human characters can teach us about what it means to be human. Then, Bruce Betts, Planetary Society Chief Scientist, joins for What's Up and a discussion of solar sails in the franchise.

Star Trek at 60: What do we value the most? (Part 1)

We tend to think of private space exploration as a recent phenomenon. But as Alex MacDonald, former Chief Economist at NASA, argues in his book "The Long Space Age," privately funded space exploration has deep roots in American history, stretching back more than two centuries.

In this 2017 conversation with The Planetary Society's Chief of Space Policy Casey Dreier, originally aired on the Space Policy Edition of Planetary Radio, MacDonald traces the economic history of American space exploration from the 1769 transit of Venus all the way to the present day, and makes the case that the government-dominated model we grew up with may actually be the historical anomaly.
