It was such a delight to feature work by our own Kate Howells in The Planetary Society’s member book club. We keep Kate busy as our public education specialist, but she found time to write about many of her favorite natural satellites in this richly illustrated edition. Join her and book club host Mat Kaplan for a journey taking us from our own Moon, past Europa, Titan, and many more, and out across a galaxy that is no doubt full of worlds circling other worlds.

Book Club Edition: MOONS: The Mysteries and Marvels of our Solar System by Kate Howells

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.

Space Policy Edition: The Long Space Age with Alex MacDonald

Dennis Stone, president and co-founder of the World Space Week Association, takes us behind the scenes of the largest annual space event on Earth. From its origins as a volunteer effort in Houston to a UN-declared celebration reaching 50,000 events in over 100 countries, Dennis shares how World Space Week inspires the next generation, and how you can get involved this Oct. 4 through 10. Then, Science Editor Asa Stahl breaks down the end of the Neil Gehrels Swift Observatory, the 21-year-old space telescope that's falling out of orbit after a bold rescue mission fell short. Plus, Chief Scientist Bruce Betts looks back at a milestone centennial in this week's What's Up, 100 years since Robert Goddard launched the world's first liquid-fueled rocket.
