Planetary Radio: Space Exploration, Astronomy and Science

NASA's Psyche mission's principal investigator, Lindy Elkins-Tanton, shares her emotional experience of watching her team's spacecraft blast off. Jesse Tomlinson and Stephen Watkins from the Eclipse Company discuss their partnership with The Planetary Society and the launch of a new eclipse map for the upcoming 2024 total solar eclipse in North America. The podcast also explores topics like the challenges and successes of space missions, planning eclipse viewing trips, the importance of educating about solar sailing, finding ideal eclipse viewing locations, and rocket launch delays.

Simone Marchi, co-investigator for the Psyche mission, discusses the creative ways their team studies cratering on metallic worlds, including computer modeling and blasting meteorites. They also explore surprise elements when exploring asteroids up close and discuss structural differences in craters on metallic surfaces compared to the moon or Mars.

Data from the now-retired NASA InSight mission suggests that Mars' rotation is speeding up. The InSight RISE instrument's principal investigator, Sebastien Le Maistre, from the Royal Observatory of Belgium, joins Planetary Radio to get into the details. The Planetary Society's Digital Community Manager, Ambre Trujillo, shares her experience observing the October 14 annular solar eclipse and her adventure to the OSIRIS-REx sample return capsule opening at Johnson Space Center. Then, our Director of Government Relations, Jack Kiraly, shares the triumphs of The Planetary Society's in-person Day of Action. Stick around for What's Up with Bruce Betts, the chief scientist of The Planetary Society, as he shares an asteroid mission-themed random space fact.

Planetary Radio celebrates the successful return of NASA's OSIRIS-REx sample from asteroid Bennu. Rae Paoletta shares her firsthand experience in Utah, and introduces Mike Puzio, the person who named Bennu. Danny Glavin discusses the next steps for the samples. Excitement builds for studying origins of life on Earth and future missions.

Join Planetary Radio host Sarah Al-Ahmed for part two of her trip to the 2023 NASA Innovative Advanced Concepts (NIAC) Symposium in Houston, Texas.  You'll hear from Mike LaPointe and John Nelson, the NIAC Program Executive and Deputy Program Executive along with Theresa Benyo (NASA Glenn Research Center), Lynn Rothschild (NASA Ames Research Center), and Javid Bayandor (State University of New York).

Join Planetary Radio host Sarah Al-Ahmed on a trip to the 2023 NASA Innovative Advanced Concepts (NIAC) Symposium in Houston, Texas. In this jam-packed two-part series, you'll hear Sarah's interviews with the inspiring NIAC fellows who are thinking up the technologies that could change the future of space exploration. In this episode, you’ll hear from Congrui Grace Jin (University of Nebraska, Lincoln), Quinn Morley (Planet Enterprises), Ronald Polidan (Lunar Resources, Inc.), and Edward Balaban (NASA Ames Research Center). Stick around for What's Up with Bruce Betts, the chief scientist of The Planetary Society, for a discussion about the advances in space exploration during our lifetimes.See omnystudio.com/listener for privacy information.

Louis Friedman, one of the three co-founders of The Planetary Society, joins Planetary Radio to discuss his new book, "Alone but Not Lonely: Exploring for Extraterrestrial Life." The book takes us on a realistic but hopeful reflection on the search for life, from habitable worlds to the technologies that might allow us to explore exoplanets without leaving our stellar backyard. Then stick around for What's Up with Bruce Betts, chief scientist of The Planetary Society, as we get his hot take on life in the universe.   Discover more at: https://www.planetary.org/planetary-radio/2023-alone-but-not-lonely See omnystudio.com/listener for privacy information.

Carver Bierson from Arizona State University discusses how Jupiter's radiant beginnings might have turned Io from a water-rich moon into a world with lakes of lava. Voyager project manager Suzanne Dodd and Voyager project scientist Linda Spilker share their endeavor to reestablish contact with Voyager 2. Other topics include retaining atmosphere and water on moons, the mystery of Europa's ocean, upcoming missions to Jovian moons, and the journey of helium.

Lujendra Ojha, assistant professor at Rutgers University, discusses subsurface liquid water on exoplanets orbiting red dwarf stars and its potential for habitable worlds. They explore the Trappist system, Proxima Centauri B, and the prevalence of M-dwarf stars. They also discuss factors impacting basal bounty on exoplanets, challenges of melting ice, and the potential for life beneath ice sheets.

A next-generation asteroid discovery algorithm, HelioLinc3D, has successfully identified its first potentially hazardous asteroid. Mario Jurić and Ari Heinze from the University of Washington join Planetary Radio to discuss the upcoming Vera Rubin Observatory and how their team's new asteroid detection algorithm can help defend our world. The Planetary Society editorial director, Rae Paoletta, marks the successful landing of the Indian Space Research Organization's (ISRO's) Chandrayaan-3 mission on the Moon. Then Bruce Betts, the chief scientist of The Planetary Society, pops in for What's Up and a conversation about space dreams.    Discover more at: https://www.planetary.org/planetary-radio/2023-algorithm-potentially-hazardous-asteroid See omnystudio.com/listener for privacy information.
