Scientists have discovered over 5,500 exoplanets, but they’re just getting started. We dive into the stunning variety of exoplanets beyond our Solar System with Jessie Christiansen, the project scientist for the NASA Exoplanet Archive. But first, The Planetary Society's science editor, Asa Stahl, shares more about the upcoming Habitable Worlds Observatory, a cutting-edge space telescope designed to hunt for worlds that could harbor life. We also give an update on the International Space Station with our senior communications advisor, Mat Kaplan. Stick around for What's Up with Bruce Betts as we discuss the advances in exoplanet detection and share a new Random Space Fact.

Every year on June 30, the space community observes Asteroid Day, the anniversary of the Tunguska blast. Markus Payer, Asteroid Foundation Chair, joins us to talk about this year's Asteroid Day festivities. We also get an update on the results of the Double Asteroid Redirection Test (DART) with Terik Daly, a planetary scientist and the Planetary Impact Laboratory manager at Johns Hopkins Applied Physics Lab. He’ll tell us more about the aftermath of DART’s smashing encounter with asteroid Dimorphos. Then Bruce Betts, our chief scientist, discusses what The Planetary Society’s asteroid-hunting grant winners have been up and in What's Up.

Holy texts and salvation ideology. Saints and martyrs. True believers and apostates. This isn’t a religion — this is human spaceflight. So says Roger Launius, NASA’s former Chief Historian, in his 2013 paper Escaping Earth: Human Spaceflight as Religion. For the start of our ninth year of the Space Policy Edition, Dr. Launius joins the show to discuss the ways in which human spaceflight exhibits characteristics commonly seen in modern religions, how his thesis has evolved in the past decade with the rise of Elon Musk and his view of Mars as humanity’s salvation, and how exploring secular activities through a religious lens can be instructive in understanding their adherents and support.

Every year, passionate space advocates from the United States travel to Washington, D.C., to ensure that their vision for the future of space exploration gets the funding and support it needs. Nearly 100 advocates gathered this year on Monday, April 29, 2024, to call for increased funding and better support for NASA's groundbreaking science programs. This week on Planetary Radio, we'll share what happened during this year's Day of Action and why it matters. You'll hear from members of The Planetary Society staff, space advocates from across the United States, and various congresspeople, including the co-chairs of the Congressional Planetary Science Caucus, Representatives Don Bacon and Judy Chu. We close out our show with Bruce Betts for What's Up and a new random space fact.
