2026/04/08

Four astronauts — Commander Reid Wiseman, Pilot Victor Glover, Mission Specialists Christina Koch and Jeremy Hansen — are on their way around the Moon, on a journey that will take them farther from Earth than any human has gone before. This week on Planetary Radio, we bring you the sounds of launch day and the voices of the people who lived it. You’ll hear from the engineers who built the spacecraft, including Mark Tobias, chief engineer at Northrop Grumman, Jan-Henrik Horstmann,

What makes Cape Canaveral the center of U.S. spaceflight? The answer is a fascinating mix of geography, military strategy, Cold War politics, and a fair amount of historical accident. In this episode of the Space Policy Edition of Planetary Radio, host Casey Dreier, chief of space policy at The Planetary Society, sits down with Stephen C. Smith, author and writer behind the Substack The Space Pundit, to discuss his book Return to Launch: Florida and America's Space Industry. A longtime Kennedy Space

2026/04/01

Artemis II is the first crewed lunar mission since Apollo 17, and riding alongside the crew is one of the most ambitious biology experiments ever sent to space. It's called AVATAR, short for A Virtual Astronaut Tissue Analog Response: tiny organ chips grown from the astronauts' own cells, flying the same trajectory around the Moon, exposed to the same deep-space radiation and microgravity as the crew themselves. Lisa Carnell, director of NASA's Biological and Physical Sciences Division, explains

Artemis II is about more than getting four humans to the Moon and back. It's an opportunity to gather data on human health in deep space that we haven’t had in over 50 years. This week, we’re joined by Steve Platts, chief scientist of NASA's Human Research Program, who walks us through the suite of human health experiments flying aboard Artemis II, from the ARCHER wearable sensors tracking crew health and team dynamics, to dry saliva swabs measuring stress hormones. Then Casey Dreier,

Join us for an awe-inspiring conversation with astrobiologist and astronomer Caleb Scharf as he eloquently makes the case for "dispersal," the nearly inevitable advance of life and humanity across our solar neighborhood. From the book: "The idea of Dispersal is one where the sheer scale and scope of life’s future extension into the solar system profoundly changes things: not because of some new (and unlikely) cultural enlightenment from within but because of what the enormous expanse of space

Humanity is going back to the Moon, and Europe is already playing a critical role in making it happen. This week, Planetary Radio brings you voices straight from the 18th European Space Conference in Brussels, Belgium, where more than 2,000 of the world’s top space leaders gathered to shape the future of European space exploration. We begin with conference co-organizer Tomas Dimitrov of Logos and Business Bridge Europe, who sets the stage for the conversations ahead. From there, we hear from

Gentry Lee spent nearly five decades at NASA's Jet Propulsion Laboratory, and in that time he helped shape some of the most ambitious missions in the history of space exploration. A new documentary, “Starman,” chronicles his career and the big question that runs through it: is there life beyond Earth? Lee worked on every NASA mission to land on Mars, helped Carl Sagan bring the Universe to living rooms around the world with “Cosmos,” and oversaw dozens of active missions as

Is the United States really in a new space race with China? Or is that framing missing the bigger picture? In this Space Policy Edition of Planetary Radio, Casey Dreier, chief of space policy at The Planetary Society, sits down with Patrick Besha, former NASA strategic advisor on China, to explore the realities behind China’s rapidly advancing space program. They discuss how China’s political system shapes its long-term space strategy, why the rhetoric about a “space race”

2026/03/04

NASA has announced a major restructuring of the Artemis program, reshaping the roadmap for returning humans to the Moon. At a February 27 press conference, agency leadership addressed the rollback of Artemis II following post–wet–dress–rehearsal testing and unveiled significant changes to upcoming missions, including shifting Artemis III from a planned lunar landing to a low-Earth-orbit rendezvous and integrated systems test. In this episode, you’ll hear remarks from NASA

Did an impact trigger cryovolcanism on Umbriel?

2026/02/25

Could a single ancient impact have briefly transformed one of the Solar System’s darkest moons into a cryovolcanic world? When Voyager 2 flew past Uranus in 1986, it captured the only close-up images we have of Umbriel, a heavily cratered, charcoal-dark satellite long considered geologically inactive. But one feature stands out: a bright ring inside the 131-kilometer-wide Wunda crater. In this episode, Sarah Al-Ahmed speaks with Adeene Denton, NASA postdoctoral program fellow at the Southwest

Our Solar System is wrapped in a vast, invisible bubble created by the Sun, a protective region that shields Earth and the planets from much of the radiation that fills our galaxy. But until recently, scientists have only had rough sketches of what this boundary looks like and how it behaves.
