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

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.

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.

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.

After decades of development, the Nancy Grace Roman Space Telescope is preparing to launch. Once in orbit, Roman will conduct the widest surveys of the universe ever attempted, probing the nature of dark energy, discovering thousands of new exoplanets, and capturing images of billions of galaxies. In this episode, we sit down with Julie McEnery, senior project scientist for Roman at NASA's Goddard Space Flight Center, and Jason Rhodes, project scientist for Roman at NASA’s Jet Propulsion Laboratory, to explore what the telescope will reveal and how scientists around the world will be able to access and work with its data. Plus, in What's Up, we look at Roman's coronagraph and what it will take for the Habitable Worlds Observatory to push that technology far enough to image Earth-like worlds around Sun-like stars.

Will we change or terraform Mars to better suit humans? Or are we more likely to change ourselves to better fit the red planet? How far can evolution take us in these new and exotic environments? These and many other fascinating questions are at the heart of Rice University professor Scott Solomon’s great book, “Becoming Martian”. He joins host Mat Kaplan for a far-ranging conversation in this month’s installment of Planetary Radio’s book club edition.  Discover more at: https://www.planetary.org/planetary-radio/book-club-scott-solomonSee omnystudio.com/listener for privacy information.

A SpaceX Falcon 9 upper stage slammed into the moon on August 5 after spending over a year and a half drifting through the Earth-Moon system. Jared Head, museum facilitator at Columbia Memorial Space Center, producer at TMRO, and co-host of All Space Considered at Griffith Observatory, walks us through how a rocket launched in January 2025 ended up crashing into the lunar surface. Kate Howells, the Planetary Society's public education specialist, shares her experience witnessing Europe's first total solar eclipse in 27 years from a canyon in Spain on her honeymoon. Plus, Jack Kiraly, the Planetary Society's chief of advocacy, gives us an update on the campaign to save NASA science and the proposed changes to OMB's federal grant-making rules. We close with Bruce Betts, our chief scientist, who joins for What's Up, to discuss Point Nemo, the spacecraft graveyard in the South Pacific.

On August 12th, 2026, the Moon’s shadow will sweep across Iceland, Greenland, and Spain, bringing the first total solar eclipse visible from Europe since 1999. And because this eclipse happens near sunset, it promises to be one of the most visually stunning in living memory. Astrophotographer Andrew McCarthy, founder of Cosmic Background Photography, joins the show to talk about his extraordinary 2024 eclipse image, his collaboration with the Artemis II crew to capture the Moon in unprecedented detail, and what he's planning for this unique low-horizon eclipse. Then, bioacoustics researcher David Mann, founder of Haikubox and Loggerhead Instruments, shares the results of the Eclipse Echoes study, which used a network of hundreds of AI-powered bird monitors to reveal how birds across North America responded to the 2024 eclipse. The answer is far more complicated than simply going quiet. Discover more at: https://www.planetary.org/planetary-radio/2026-total-solar-eclipseSee omnystudio.com/listener for privacy information.

The White House's Office of Science and Technology Policy recently released "Science: A New Golden Age", a sweeping report that calls for a fundamental reimagining of how the United States funds and conducts science. Explicitly modeled on Vannevar Bush's landmark 1945 report "Science, the Endless Frontier," it challenges the traditional linear model of innovation, advocates for empowering individual scientists over institutions, proposes faster grants with less bureaucracy, and envisions a greater role for AI in the scientific process. But this ambitious vision arrives in a deeply contradictory context: the same administration has proposed slashing science agency budgets, cutting new NSF funding awards by over 50%, and imposing new bureaucratic controls on scientific grants. Casey Dreier is joined by Zach Pirtle, deputy director of the Consortium for Science, Policy and Outcomes at Arizona State University, and the Planetary Society's Chief of Advocacy Jack Kiraly to unpack the report's proposals, tensions, and implications.  Discover more at: https://www.planetary.org/planetary-radio/space-policy-edition-science-a-new-golden-ageSee omnystudio.com/listener for privacy information.

For the first time, scientists have confirmed an atmosphere on a rocky exoplanet in the habitable zone of another star. Sarah Al-Ahmed is joined by Collin Cherubim, NASA Hubble Fellow at the University of Chicago, to discuss his team's detection of helium escaping from the super-Earth LHS 1140b, and what it reveals about how rocky worlds build, transform, and lose their atmospheres over time. His team's paper, published in the journal Science, marks a milestone decades in the making. Then Bruce Betts, chief scientist of The Planetary Society, joins for What's Up, where we dig into the very first exoplanet atmosphere ever detected and its surprising connection to this week's guest.

On Friday, April 13, 2029, asteroid Apophis will pass closer to Earth than our geostationary satellites. While NASA, ESA, and JAXA are all sending missions, a team of students at the University of Maryland is building their own spacecraft to join the fleet. TERP RAPTOR is a CubeSat-based mission roughly the size of a microwave that aims to fly past the asteroid and snap images of its surface as it approaches Earth. Four members of the team join Planetary Radio: Adrienne Rudolph, the Student Principal Investigator; Elena Wu, the Lead Project Manager; Tyler Autrey, the Mechanical, Structure, and Materials Lead; and Alexander Williams, the Propulsion Lead. Together, they talk about how a graduate class project turned into a real mission, what they hope to learn about this potentially hazardous asteroid, and why they're not letting anyone tell them it can't be done. Then, Bruce Betts joins us for What's Up, where we mark the deployment anniversary of The Planetary Society's own CubeSat-based solar sail mission, LightSail 2.
