Planetary Radio: Space Exploration, Astronomy and Science

Mars all-stars gathered online for September’s annual Humans to Mars summit produced by Explore Mars. Planetary Radio host Mat Kaplan moderated three intriguing panels with participants including leaders from space agencies throughout the world. Then we hear about the 19th century’s biggest telescope in this week’s What’s Up segment with Bruce Betts.  Learn more at https://www.planetary.org/planetary-radio/2021-humans-to-mars-summit-excerptsSee omnystudio.com/listener for privacy information.

Clare Lewins has created a film that takes us inside the lives of people who have lived and worked on the International Space Station. Cady Coleman is one of the featured astronauts in this beautiful, intimate and very affecting documentary. Planetary Society contributor Jatan Mehta tells us about South Korea’s plans for a lunar orbiter with an amazing camera. Bruce Betts returns with yet another space trivia contest and a quick tour of the night sky.

Morgan Cable of NASA’s Jet Propulsion Laboratory is lead author of a paper that makes a compelling argument for a mission to Saturn’s small but dynamic moon Enceladus. She and her stellar co-authors believe it is among the best and easiest places in our solar system to look for evidence of life. Morgan has also been involved with the synthesis of organic crystals that could exist on Titan. What would they mean for possible biological activity on that big moon? Bruce Betts shares his excitement about the current night sky in What’s Up. https://www.planetary.org/planetary-radio/morgan-cable-enceladus-titan-co-crystalsSee omnystudio.com/listener for privacy information.

NASA hopes to radically reduce the price tag for exploring Mars with a mission called ESCAPADE. Principal investigator Rob Lillis and his team will send two small probes to the Red Planet in 2024 for less than $80 million. They will work with orbiters already circling Mars to answer deep questions about the evolution of that world’s formerly thick atmosphere and the effects of solar radiation. Then we’ll check in with Planetary Society chief scientist Bruce Betts for another What’s Up.

Communication is culture, says Dr. Linda Billings, an expert in social science and space outreach. So what culture is summed by the types of space advocacy that call for pioneering, colonization and conquest of nature? Linda talks about the importance of language and context when advocating for space, and how we should consider other cultural values and frameworks for effective public engagement.

It was one of the most exciting planetary science announcements in 2018: Radar from an orbiting spacecraft might have found large pools of liquid water under the Martian south pole. But good science doesn’t end with first conclusions. Jeffrey Plaut and Isaac Smith are among the researchers who have found that a form of clay may better explain these reflections. We also talk with The Planetary Society’s Rae Paoletta about the Earth-like worlds found across our corner of the galaxy. Your chance to win the coveted Planetary Society rubber asteroid returns in this week’s What’s Up.

Jupiter’s moon Europa hides a vast water ocean under a protective layer of ice. The Europa Clipper mission will send a powerful orbiter to investigate. Mission system manager L. Alberto (Al) Cangahuala tells us about the great strides made toward a planned 2024 launch and the challenges ahead. Bruce Betts faces one of the greatest challenges for any parent: getting a new college freshman installed in a distant university. Our chief scientist takes a break from the preparation to share the night sky and a new space trivia contest.

Cassini project scientist Linda Spilker is back to describe how data from the Saturn mission that ended four years ago is behind new, trailblazing science. Linda has also rejoined the team behind NASA'S Voyager mission that is celebrating important anniversaries. She closes with convincing arguments for missions to Saturn’s moon Enceladus and the ice giants Uranus and Neptune. Bruce Betts gets on the Cassini train with this week’s space trivia contest.

NASA’s Perseverance is driving farther and faster than any previous Mars rover, thanks to its advanced AutoNav system. Vandi Verma, the mission’s chief engineer for robotics at NASA’s Jet Propulsion Laboratory, takes us inside the speedy, six-wheeled robot for a look at its marvelous mechanics and software. Vandi also describes the complex process of sample collection. There’s a high-flying surprise for Bruce Betts in the space trivia contest.

Can nuclear propulsion fundamentally transform our ability to send humans to Mars? Bhavya Lal, a policy and nuclear engineering expert now working at NASA, helped write a new report on the topic for the National Academies of Sciences. She joins the show to talk about the advantages of various types of nuclear propulsion, the engineering and policy challenges that face them, and the role of government versus the private sector in developing and deploying transformational technologies.
