Hide and seek with Planet 9

Join us on a journey to the 2024 NASA Innovative Advanced Concepts (NIAC) Symposium. We'll hear from the teams behind two NIAC projects that could help us study distant planets and potentially reach them ourselves. Marshall Eubanks from Space Initiatives, Inc. and his colleagues will introduce us to their concept for a swarm of laser sailing pico spacecraft that could travel interstellar distances. Then Ryan Sprenger from Fauna Bio Inc. joins us to discuss how hibernation could help humans reach other worlds. Then, our chief scientist, Bruce Betts, joins us for What's Up and a new random space fact.

We are near solar maximum, a time in the solar cycle when our Sun is most active. That means more sun spots, coronal mass ejections, and auroras on worlds across our solar system. This week, Vince Ledvina, also known as the Aurora Guy, joins Planetary Radio to discuss the science behind the northern and southern lights and what they can tell us about our Sun, our planet, and worlds across our galaxy. Then Bruce Betts joins in for What's Up, a chat about global magnetic fields on terrestrial worlds and a new random space fact.

Dr. Greg Autry, who served on Trump’s NASA transition team in 2016 and was nominated for the position of NASA CFO in 2020, joins the show to discuss the space policy issues facing a potential second Trump administration in 2025. We discuss the role of competition versus cooperation in space exploration, how space politics have changed since Trump’s first term, and what major issues at NASA must be faced by the next presidential administration.

With less than two months to go until the highly anticipated launch of NASA's Europa Clipper mission, we take a look back at over twenty years of Planetary Radio episodes about Jupiter's most intriguing moon. You'll hear from Elizabeth 'Zibi' Turtle, planetary scientist at Johns Hopkins Applied Physics Lab, Bob Pappalardo, project scientist for Europa Clipper, and many more, as we reflect on all of the dreams and science it took to make the upcoming mission a reality. Then, Bruce Betts, our chief scientist, joins in for What's Up as host Sarah Al-Ahmed gears up for next week's NASA Innovative Advanced Concepts symposium.  Discover more at: https://www.planetary.org/planetary-radio/2024-europa-in-reflectionSee omnystudio.com/listener for privacy information.

Get up to speed on the latest in commercial space news. Mat Kaplan, the senior communications advisor for The Planetary Society, returns with an update on the fate of the Boeing Starliner astronauts, the imploding and exploding adventures of Blue Origin's New Glenn rocket, and a brief look forward to SpaceX's Polaris Dawn mission. Asa Stahl, our science editor, shares the good news about the European Space Agency's Ramses mission, which hopes to rendezvous with asteroid Apophis before its closest approach to Earth in 2029. Then our public education specialist, Kate Howells, shares some tips on how to deal with space rocks in her new article, "What would happen if we nuked an asteroid?" We end our show with What's Up with Bruce Betts, our chief scientist, and a new random space fact.

As we look to build a more sustainable human presence in space, we will need to find new and innovative ways to feed our travelers. This week, we hear from Team Insecta, a group of Canadian students exploring crickets as a viable source of space food. Newton Campell Jr., a member of The Planetary Society's board of directors and co-founder of Heritage Space Food, discusses gastrodiplomacy and the importance of representation in space food. Then we close out with What's Up with Bruce Betts and a look at one of The Planetary Society's STEP grant-winning projects studying the complexities of growing plants in space.  Discover more at: https://www.planetary.org/planetary-radio/2024-crickets-and-gastrodiplomacySee omnystudio.com/listener for privacy information.

Planetary Radio takes a melodic adventure to the Ravinia Festival in Illinois, USA, for the public premiere of the "Moons Symphony." Mat Kaplan, senior communications advisor at The Planetary Society, speaks with a panel of amazing guests, including members of the Europa Clipper, Dragonfly, and Cassini teams, about the discoveries that inspired the music. Then, Bruce Betts, our chief scientist, marks the end of the 2024 Summer Olympics with a random space fact in What's Up.

Why do we explore space? This is not an easy question to answer. Yet policy expert G. Ryan Faith believes there is value to be had in communal engagement with this question. While easy answers may elude us, the act of defining our values and goals in space can help avoid common pitfalls and dead ends in our exploration efforts, ensuring a continued commitment to space for generations to come.

NASA's Perseverance rover has made a groundbreaking discovery on Mars: a sample that may hold evidence of ancient microbial life. This week, we visit the Tenth International Conference on Mars, where you'll hear from several Mars scientists, including Caltech's Ken Farley, Perseverance project scientist, Meenakshi Wadhwa and Brandi Carrier, the principal scientist and lead sample integrity scientist for Mars Sample Return at NASA JPL. We'll also discuss the recent cancellation of NASA's VIPER lunar mission with our director of government relations, Jack Kiraly. Before we go, we'll turn to Bruce Betts, the chief scientist of The Planetary Society for What's Up, as he shares a new cometary random space fact.
