Could the first object shown to have originated outside our solar system be a light sail built by an alien civilization? That’s the very controversial hypothesis put forward by distinguished Harvard astrophysicist Avi Loeb in his new book Extraterrestrial. The book is about much more than ‘Oumuamua, and so is Avi’s conversation with Mat Kaplan. Bill Nye pays tribute to a fallen member of The Planetary Society’s space family, and the biggest coincidence in the history of Planetary Radio surfaces during What’s Up.There’s more to discover, including a link to Planetfest ’21, at https://www.planetary.org/planetary-radio/0127-2021-avi-loeb-extraterrestrial

‘Oumuamua: Avi Loeb says it may have been artificial

The Planetary Society team reviews the best space moments of 2024, from the China National Space Administration's return of samples from the far side of the Moon to the triumphant launch of NASA's Europa Clipper mission. Kate Howells (Public Education Specialist) shares the winners of The Planetary Society's Best of 2024 awards. Then, Mat Kaplan (Senior Communications Advisor), Ambre Trujillo (Digital Community Manager), and Asa Stahl (Science Editor) team up for a rundown of the year's highlights. We close out 2024 with Bruce Betts, our chief scientist, as he shares his last random space fact of the year.

Looking back on 2024

Lauren Mc Keown, a postdoctoral fellow at NASA's Jet Propulsion Laboratory, discusses her experiences recreating Martian araneiform terrain, also called Mars spiders, in the lab. Latif Nasser, the co-host of Radiolab, also joins Planetary Radio to share how you can cast your vote to name a quasi-Moon of Earth. Then Bruce Betts, chief scientist of The Planetary Society, looks at a different type of seasonal feature on Mars, recurring slope lineae, in What’s Up.

Mars “spiders” recreated in the lab

For over half a century, space advocates and presidents alike have tried to recreate the JFK moment of calling on the country to send a man to Moon — but is this a mistake? The classic book Spaceflight and the Myth of Presidential Leadership argued that it is, and by focusing on presidential power alone advocates set up these initiatives to fail. 

However, in the decades since its publication, presidential authority has dramatically expanded. In this episode, we examine this tension: Did the success of Apollo create a false expectation about the role of presidential leadership in spaceflight? How can a president most effectively set new long-term goals for NASA?

We revisit a classic book on the limits of presidential power in setting the nation’s space agenda and explore how the increasingly powerful executive branch might be rewriting those expectations.
