An asteroid bash and an asteroid smash
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.

A big year for heliophysics and Parker Solar Probe
Our Sun is nearing the most active part of its solar cycle. This week, we explore recent solar activity and discoveries from NASA's Parker Solar Probe with Nour Rawafi, the mission's project scientist. But first, we honor the life and legacy of Ed Stone, the former director of NASA's Jet Propulsion Laboratory and the longtime project scientist of the Voyager mission. We close out our show with Bruce Betts, the chief scientist of The Planetary Society, in What's Up.

The nova and the naming contest
Last week was a big one for commercial space. Our senior communications advisor, Mat Kaplan, discusses the first crewed Boeing Starliner test and SpaceX Starship launch. Then Asa Stahl, our science editor, lets you know how to observe the upcoming nova in Corona Borealis. RadioLab's Latif Nasser returns to Planetary Radio with a new public naming contest for a quasi-moon of Earth. Then, we dive into some naming conventions for space objects in What's Up with our chief scientist, Bruce Betts.

Space Policy Edition: Is Human Spaceflight a Religion?
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.

Accidental astronomy
Astronomical and planetary science discoveries often unfold in strange and serendipitous ways. We discuss the delightfully unpredictable nature of space discoveries with Chris Lintott, author of the upcoming book "Accidental Astronomy: How Random Discoveries Shape the Science of Space." Then, Bruce Betts, our chief scientist, gives us a new way to think about the scale of our Solar System in What's Up.

Day of Action 2024: The Planetary Society goes to Washington
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.
