12.19.25 – Day 10/13 of the Red Dragon Wavespell – Rhythmic Moon 7

Thirty years ago, NASA’s Galileo spacecraft became the first mission to orbit Jupiter, opening a new chapter in our exploration of the outer Solar System. Over eight years around Jupiter, Galileo transformed how we understand Jupiter and its moons, revealing a powerful and dynamic planetary system, uncovering evidence for oceans hidden beneath icy worlds, and reshaping the search for life beyond Earth. To mark the 30th anniversary of Galileo’s orbital insertion, scientists, engineers, historians, and advocates gathered at the California Institute of Technology for a special symposium: Galileo at 30. In this episode of Planetary Radio, host Sarah Al-Ahmed takes you inside that celebration. You’ll hear how Galileo survived seemingly impossible challenges, how its team adapted when things went wrong, and how its discoveries reshaped planetary science. You’ll hear from key voices in Galileo’s story, including historian Erik Conway, project manager Bill O’Neil, magnetometer principal investigator Margaret Kivelson, Europa Clipper Project Scientist Bob Pappalardo, and Dragonfly mission Principal Investigator Elizabeth “Zibi” Turtle, along with reflections from many others whose lives and careers were shaped by this remarkable mission. Together, they tell the story of Galileo not just as a spacecraft, but as a shared human effort, one whose legacy continues to guide exploration today.

In this episode of SpaceTime, we explore significant developments in space exploration and cosmic studies that could reshape our understanding of the universe.Nasa's MAVEN Mars Orbiter: Communication LossNASA's MAVEN (Mars Atmosphere and Volatile Evolution) spacecraft has gone silent, with contact lost on December 6th after passing behind Mars. The orbiter has been a vital asset for over a decade, studying the Martian atmosphere and solar wind interactions that have transformed Mars from a water-rich world to a cold desert. We delve into MAVEN's critical findings, including the mechanisms of atmospheric escape and the implications of its potential loss for ongoing Martian research.Galactic Neighbourhoods: Influencing EvolutionA new study reveals how a galaxy's local environment can significantly affect its evolution. The research, published in the Monthly Notices of the Royal Astronomical Society, demonstrates that galaxies situated in densely populated regions tend to grow more slowly and develop different structures compared to their isolated counterparts. By analysing data from the Deep Extragalactic Visible Legacy Survey, astronomers have gained insights into the complex dynamics of galactic interactions and their impact on star formation rates.Uranus and Neptune: More Richie than Icy?Challenging long-held classifications, a recent study suggests that the solar system's ice giants, Uranus and Neptune, may actually be more rocky than icy. Researchers from the University of Zurich conducted computer simulations that indicate a broader range of internal compositions for these planets, which could explain their complex magnetic fields. This new perspective could alter our understanding of planetary formation and evolution, paving the way for future explorations of these distant worlds.www.spacetimewithstuartgary.com✍️ Episode ReferencesMonthly Notices of the Royal Astronomical SocietyNASA TVBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.

Joining host Michael Azevedo on this episode is first-time filmmaker Nivi Jaswal-Wirtjes, the director & executive producer of a powerful and thought-provoking new documentary called “Third Degree Burnout”   Narrated by renowned meteorologist John Morales, "Third Degree Burnout" uncovers the hidden connections between personal burnout and the climate crisis, revealing them as symptoms of a larger socio-economic metacrisis. With world-class animation, engaging interviews with over 20 experts, and playful humor woven into thought-provoking skits, the film breaks down complex ideas into something accessible, relatable, and impactful. From the history of our food systems to the ripple effects of the COVID-19 pandemic and the intersections of healthcare, politics, and society, this documentary offers a fresh lens on the systemic forces shaping burnout.

This revelation, published in the Astrophysical Journal Letters, highlights the complex movements of Cepheid variable stars within the galaxy, indicating that it is being stretched in multiple directions. By utilizing data from the European Space Agency's Gaia satellite, researchers have gained unprecedented insights into the interactions between these two galaxies, prompting a reevaluation of their structural dynamics and gravitational relationships with the Milky Way.Europa's Spider: Signs of Subsurface Water?A striking spider-like feature on Jupiter's moon Europa has scientists buzzing with excitement. Researchers suggest this formation, found near the Menanan impact crater, may be evidence of subsurface water seeping through the moon's icy crust following an asteroid impact. The findings, reported in the Planetary Science Journal, could have significant implications for the moon's habitability and the presence of life. By drawing parallels with similar features on Mars, scientists are eager to explore Europa's subsurface properties further, especially with the upcoming Europa Clipper mission set to launch in April 2030.Mars: A Longer Habitable History?New research indicates that Mars may have been habitable for a much longer duration than previously believed. A study published in the Journal of Geophysical Research Planets reveals that ancient underground water may have flowed beneath the Martian sand dunes, creating conditions conducive to life long after its surface water disappeared. This discovery not only enhances our understanding of Mars' geological history but also highlights the potential of subsurface environments as targets for future exploration in the search for past life.www.spacetimewithstuartgary.com✍️ Episode ReferencesAstrophysical Journal LettersPlanetary Science JournalJournal of Geophysical Research PlanetsBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.

12.6.25 – Day 10/13 of the Yellow Star Wavespell – Overtone Moon 22

Could you survive an eternal winter? Or is endless summer sun a more appealing prospect? Lots of us are grateful for the seasonal changes that shape the world around us, but this week Hannah and Dara are asking what life would look like without the axial tilt that brings each hemisphere closer and further away from the sun as the seasons change each year. Listener Andrew from Melbourne wants to know what would happen if the planet stood perfectly upright, no lean, no tilt, no seasons. But what else could happen? Is Earth's 23-degree slant the cosmic fluke that made life possible? To find out, Hannah and explore how losing the tilt reshapes climate, ecosystems, evolution and maybe even the fate of the dinosaurs.You can send your everyday mysteries for the team to investigate to: curiouscases@bbc.co.uk Contributors Dr Robin Smith - Climate modelling researcher at the University of Reading Professor Rebecca Kilner - Evolutionary Biologist and Head of the Department of Zoology at Cambridge Professor Amaury Triaud - Professor of Exoplanetology at the University of Birmingham Aidan McGivern - Meteorologist and Senior weather presenter at the MET OfficeProducer: Emily Bird Executive Producer: Sasha Feachem A BBC Studios Production

NASA’s twin ESCAPADE spacecraft have finally launched on their journey to Mars. Designed to study how the solar wind interacts with Mars’ patchy magnetic fields and drives the loss of its atmosphere, ESCAPADE is NASA’s first dual-spacecraft mission to the Red Planet and a major milestone for the SIMPLEx program’s small, low-cost planetary explorers. The mission began its voyage aboard Blue Origin’s New Glenn rocket after several weather and space weather delays, marking the vehicle’s first science launch. We begin with Ari Koeppel, AAAS Science & Technology Policy Fellow and Space Policy Intern at The Planetary Society, who was at Cape Canaveral for the prelaunch activities. Ari shares what it was like to navigate repeated scrubs and even a powerful solar storm, along with the emotional experience of watching a spacecraft carrying an instrument he helped build begin its voyage to Mars. Next, we are joined by Dr. Rob Lillis, ESCAPADE’s Principal Investigator and Associate Director for Planetary Science at UC Berkeley’s Space Sciences Laboratory. Rob explains how ESCAPADE aims to unravel Mars’ complex space environment using two coordinated orbiters, why its measurements are key to understanding atmospheric escape, and how its innovative trajectory made the mission possible after the loss of its original rideshare opportunity. Finally, Dr. Bruce Betts, Chief Scientist of The Planetary Society, returns for What’s Up to talk about why Mars produces aurora even without a global magnetic dynamo.

8/8. Global Bird Consciousness and Human Responsibility — Steven Moss — Moss concludes by emphasizing that birds represent profound indicators of planetary ecological health and human stewardship. Moss argues that human societies have repeatedly demonstrated catastrophic ecological mismanagement—from deliberate species eradication campaigns to inadvertent pesticide-driven collapse of insect populations supporting avian food chains. Moss stresses that contemporary climate-driven extinctions represent an acceleration of anthropogenic ecological destruction. Mossemphasizes that conservation requires fundamental shifts in human consciousness regarding our responsibility to non-human species and ecosystem integrity, using birds as both biological indicators and moral catalysts for sustainable civilization transformation. 1848

1/4. The Genesis of the Asteroid Hunter Mission and Early Rejections — Dante Lauretta — Lauretta, hired by mentor Mike Drake at the Lunar and Planetary Laboratory (LPL), initiated the asteroid sample return mission concept in 2004 following a pivotal meeting with Lockheed Martin's Steve Price. The team submitted its initial proposal to NASA in July 2004, which received the agency's lowest competitive ranking, designated Category 4. A subsequent refined mission proposal targeting asteroid 1999 RQ36 was formally rejected in December 2007 due to prohibitively high estimated costs relative to the NASA planetary science program budget allocation. 1930

Is Earth literally waking up? Not in a poetic, mystical sense, but in a real, scientific, and possibly terrifying way. In this mind-bending episode of The Skeptic Metaphysicians, we dive into one of the most provocative conversations we've ever hosted: the possibility that the Earth is evolving into a planetary superconsciousness, powered by artificial intelligence, fiber-optic nerve systems, and global institutions acting as synapses in a technological brain. Our guest, Topher McDougal, is not your typical spiritual thinker. He's a Professor of Economic Development & Peacebuilding at the University of San Diego's Joan B. Kroc School of Peace Studies and the author of the forthcoming book Gaia Wakes: Earth's Emergent Consciousness in an Age of Environmental Devastation (May 2025). McDougal introduces the Gaiacephalos Hypothesis, a theory that makes the Gaia Hypothesis look tame by comparison. He argues that the Earth isn't just a self-regulating system, it's on track to become literally conscious, thanks to the explosive growth of AI, global infrastructure, and what he calls the technosphere. In This Episode:What is the Gaiacephalos Hypothesis, and how does it extend the Gaia theory?How AI, machine learning, and planetary infrastructure are forming a neural network across the globeThe connection between environmental collapse and evolutionary upgradesCould the Earth eventually think, feel, or even act as an entity?Are we building a planetary cybernetic organism, and if so, who's in control?The parallels between biological evolution, planetary systems, and emergent intelligenceWhat we can learn from Black Mirror, cybernetics, and quantum consciousnessThe role of humanity: are we creators, neurons… or expendable?This episode is not science fiction. It's a serious, fascinating exploration of what happens when AI, energy systems, and environmental pressure converge on a planetary scale. Whether you're into mysticism, metaphysical science, spiritual awakening, or consciousness expansion, this is a conversation that will challenge everything you think you know about the future of Earth, and our place within it.Guest Info: Topher McDougal Website: TopherMcDougal.comBook (pre-order): Gaia Wakes – Columbia University Press (May 2025)Subscribe, Rate & Review!

11.23.25 – Day 10/13 of the Blue Eagle Wavespell – Overtone Moon 9

There was a time when almost everyone, from Alexander Graham Bell to the Wall Street Journal, believed there was a supremely intelligent civilization on Mars, one that was probably trying to talk to Earthlings. Most of this belief could be traced to an amateur astronomer and charismatic speaker named Percival Lowell. David Baron tells this story in “The Martians: The True Story of an Alien Craze that Captured Turn-of-the-Century America,” the product of seven years of research into this strange chapter of history. He shares many of the most surprising, fascinating, and very entertaining details, including much that had been lost to history, in this book club conversation with Mat Kaplan.

When his filmmaking career stalled during the pandemic, Toby Lockerbie turned to the one place that had never stopped inspiring him: the Universe. With no background in visual effects, he taught himself the tools needed to transform complex space science into cinematic stories using everyday objects and beautifully crafted visuals to make the Cosmos feel human. His channel, Epic Spaceman, now reaches millions and has earned multiple Webby Awards for its innovative approach to visualizing scale, awe, and accessible science. This week on Planetary Radio, Toby joins host Sarah Al-Ahmed to discuss the creation of Epic Spaceman, how visual metaphors can change how we understand the Universe, and why awe remains one of the most powerful tools for science communication. Then we welcome Bruce Betts back for What’s Up, where we reflect on the end of the Japanese Aerospace Exploration Agency’s Akatsuki mission to Venus.

The Planetary Society heads to TwitchCon 2025 to explore how scientists and educators use livestreaming to share the excitement of discovery. We begin with Moohoodles, one of Twitch’s pioneering space science streamers and co-host of the live panel “The Planetary Society: Space, Time, and You.” She explains how she built a thriving community around astrobiology and space exploration long before Twitch even had a Science & Technology category. Then we share moments from the panel, featuring a special video message from Bill Nye, CEO of The Planetary Society, and highlights of how livestreaming helps inspire new audiences to look up. At the Science & Technology Meet and Greet, Sharkg33k and Paleontologizing explain how their streams connect life on Earth to exploration beyond our planet. Later, Jack Kiraly, The Planetary Society’s Director of Government Relations, joins the show for a Space Policy Update on Jared Isaacman’s renomination as NASA Administrator, examining what it could mean for the agency’s leadership and direction. The episode wraps up with What’s Up with Bruce Betts, The Planetary Society’s chief scientist, celebrating the third anniversary of the end of the LightSail 2 mission and sharing a new random space fact.

Membership | Donations | Spotify | YouTube | Apple Podcasts | Discord | FB GroupThis week (actually, April) I speak with Rimma Boshernitsan (Website | LinkedIn), a speaker, interviewer, facilitator, and advisor who has partnered with senior leadership at Fortune 500 companies—including Google, Kaiser Permanente, Roche, TATA, and Aesop—guiding them through transformation and growth. Her writing has appeared in Fast Company, Inc. Magazine, Tech Crunch and Forbes.She began her career in management consulting at Deloitte, focusing on M&A and large-scale transformation, before moving into industry advising across healthcare, consumer business, and telecommunications. Later work in the art world taught her how cultural and political insights could drive innovation and transformation in business, leading her to found DIALOGUE in 2016.She now combines strategic foresight, human-centered innovation, and interdisciplinary thinking to help her clients reframe challenges, identify opportunities, and lead with intention. She sits on the board of trustees at Headlands Center for the Arts and on the SECA Council Board at SFMOMA, and is also an advisor to Stanford's Women in Design Program.Her most recent focus is in co-intelligence: integrating human, machine, and planetary intelligence to build future-facing organizations.I'm glad to have such an excellent partner in conversation to, as the Taoists say, “Feel our way across the river stone by stone” in a discussion about all of this and more: the re-emergence of nomadic populations and intentional communities, fumbling toward an idea of planetary culture, the role of intuition in leadership and biophilia in the design of our work spaces...it's a marvelously nondisciplinary co-exploration.There are well over a dozen episodes in the editing queue and founding members can access the entire trove of unedited conversations before they're released:✨ Show Links• Dig into nine years of mind-expanding conversations• Learn more about the Humans On The Loop project and its goals• Browse the books we discuss on the show at Bookshop.org• Contact me if you have a problem you think I can help you solve• Explore the interactive knowledge graph grown from over 250 episodes• Explore the Google Notebook for How To Live In The Future, my five-week science and philosophy course at Weirdosphere✨ Mentioned Media & PeopleIn Threads' dwindling engagement, social media's flawed hypothesis is laid bareIn a Time of Stress, Neuroaesthetic Spaces and Places Create a Path to Healing and HopeThe Triad of Intelligences: Harnessing Machine, Planetary, and Human Intuition in The Age of AIDIALOGUE Interviews: Ivy RossDIALOGUE Interviews: Susan MagsamenDIALOGUE Interviews: Kevin KellyMore Is Different: Broken symmetry and the nature of the hierarchical structure of scienceNikki SilvaBruce LiptonEd BernaysKen Wilber This is a public episode.

In this episode of SpaceTime, we explore remarkable discoveries and hypotheses that could redefine our understanding of planetary atmospheres and our journey back to the Moon.Phosphine Discovery in Brian Dwarf Wolf 1130CFor the first time, astronomers have detected phosphine in the atmosphere of the brown dwarf Wolf 1130C, raising intriguing questions about its presence and the chemistry of such celestial bodies. This discovery, reported in the journal Science, highlights the significance of phosphorus as a potential biosignature for life and challenges previous theories regarding the abundance of phosphine in other brown dwarfs and gas giants. The episode delves into the implications of this finding and what it means for our understanding of phosphorus chemistry in the universe.A New Hypothesis for Planetary Water FormationA groundbreaking hypothesis suggests that some planets may produce water during their formation through reactions between rocks and hydrogen under extreme pressure. This new perspective, discussed in the journal Nature, could explain the presence of liquid water on exoplanets located close to their host stars, challenging traditional views of water's origins. The episode examines the laboratory experiments that led to this hypothesis and its potential impact on our understanding of planetary habitability.Preparing for Humanity's Return to the MoonAs NASA gears up for the Artemis 2 mission, which aims to send humans around the Moon, we discuss the significance of returning to the lunar south pole. This area is believed to contain more water than any other region on the Moon, making it a crucial target for future exploration. The episode highlights the advancements in technology and international collaboration that will pave the way for a sustained human presence on the Moon, furthering our exploration of the solar system.www.spacetimewithstuartgary.com✍️ Episode ReferencesSciencehttps://www.sciencemag.org/Naturehttps://www.nature.com/Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.Phosphine Discovery in Brian Dwarf Wolf 1130CA New Hypothesis for Planetary Water FormationPreparing for Humanity's Return to the Moon

In 1996, a controversial claim of fossilized life in a Martian meteorite ignited a golden age of Mars exploration. Nearly 30 years later, a potential biosignature detected by the Perseverance rover at Jezero Crater has sparked…nothing, not even a formal effort to revive the beleaguered robotic Mars Sample Return project. Why did the claims surrounding the Allan Hills meteorite (which were ultimately rejected) kick off 25 years of unprecedented robotic exploration of the Red Planet? And why did the discovery at Cheyava Falls fail to ignite the same level of interest? Lou Friedman, former Executive Director of The Planetary Society and longtime proponent of Mars Sample Return, joins the show to contrast these to tipping points of Mars exploration, and argues why space scientists should seize this discovery to push for a scientific future at the Red Planet.

If we ever meet intelligent extraterrestrials, will we even be able to talk about physics? Physicist Daniel Whiteson of UC Irvine and cartoonist Andy Warner join Sarah Al-Ahmed to explore one of science’s strangest and most profound questions: if alien civilizations exist, would their understanding of the Universe look anything like ours? Their new book, “Do Aliens Speak Physics?”, discusses the nature of knowledge itself, asking whether math and physics are truly universal, or if even our most “objective” truths are shaped by our human perspective. Together, they consider what it would take to communicate with alien intelligence and how humor and illustration can make those big cosmic ideas feel surprisingly down-to-Earth. Then, stick around for What’s Up with Bruce Betts, as we discuss how difficult it is to explain physics to humans, let alone extraterrestrial life.

Ep. 206 (Part 1 of 2) | In this extraordinary, compelling conversation, visionary, activist, and long-time politician, former Governor of California Jerry Brown gets right to the heart of the things that matter most. From truth seeking on an individual level (the importance of inquiring into the depths of our reality), to the challenge of our democracy (getting a consensus in a population that has no coherence), to the problem of leadership (now it's all about winning, which works on the football field but not for international relations), the fear and greed that drive the arms race (we're not talking about the arms issue, and to not talk about it is to be complicit), and the existential danger of nuclear war (as important as it is underreported), Jerry nails the essence of our most pressing issues. Jerry's deep concern about the existential threats we face today, such as nuclear war and climate change, is matched by his enthusiasm for life and excitement over the fact that the future is unknowable. “We have to turn,” he says, “and everyone can contribute to amplifying the turn.” We discover some of the key formative events that shaped Jerry's keenly discerning character, so evident throughout his career and still today in his eighties, and why co-host Roger Walsh describes him as a “force of nature.” This conversation is thoroughly enjoyable, inspirational, eye opening, and disturbing too. “We are on the brink, but no one wants to hear it,” Jerry says. “How do you speak the truth in a way it can be heard?” Recorded August 7, 2025.“We should not sleep in the delusion that things are better than they are.”Topics & Time Stamps – Part 1Introducing former Governor of California, Jerry Brown (00:43)Jerry's Jesuit background and the transformative process (02:29)What shaped Jerry's orientation to life?

We begin with Ari Koeppel, AAAS Science & Technology Policy Fellow and Space Policy Intern at The Planetary Society, who shares why this moment matters for scientists facing uncertainty about their future. Then Britney Schmidt, planetary scientist at Cornell University and member of The Planetary Society’s Board of Directors, calls in from Washington, D.C., to share what it’s like on the ground as hundreds of advocates come together to defend the future of space science. Next, we take you to the press conference on the steps of the U.S. Capitol, featuring Bill Nye, CEO of The Planetary Society, Representative Glenn Ivey of Maryland’s 4th District, Marcel Agüeros, president-elect of the American Astronomical Society, and Brandon Jones, President of the American Geophysical Union. Together, they urge Congress to restore NASA’s science funding and maintain the United States' leadership in discovery. We close with Casey Dreier, chief of space policy at The Planetary Society, reflecting on the power of grassroots advocacy and what comes next for the Save NASA Science campaign. Finally, in What’s Up, Bruce Betts, The Planetary Society’s chief scientist, joins host Sarah Al-Ahmed to look ahead, exploring the great mysteries we could solve in the coming years if we continue to invest in space science.
