Podcasts about The Planetary Society

On October 6, 2025, hundreds of space advocates from across the United States joined The Planetary Society and 20 partner organizations on Capitol Hill to deliver one clear message: protect NASA’s science budget. 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.

How old is the earth? According to The Planetary Society it's 4.54 billion years old and we're told that the evidence for that age is overwhelming. On the other hand, creationists that hold to the literal teachings of the Bible believe that the earth is roughly 6,000 years old. They, too, will say that the evidence is overwhelming for their position. What is the reason for this massive discrepancy and what exactly does the evidence show? Joining Jim to answer that question was Dr. Terry Mortenson. Dr. Mortenson has a PhD in history of geology from Coventry University in England. He is a speaker, writer, and researcher with Answers in Genesis. How could there be such a drastic difference in opinions regarding the age of the earth? Are both sides looking at the same evidence? Dr. Mortenson noted that both sides are looking at the same rocks and fossils, the same radioactive isotopes, the same erosional features and more. The problem is that each side is interpreting the evidence through two different sets of assumptions. Evolution stems from a uniformitarian worldview. This assumes that nature is all that exists and everything must be explained via time plus chance plus the laws of nature working on matter. Finally, they assume that the processes of geological change continue at the same rate, frequency and power as they always have. Evolutionists use this as their starting assumption. From there the program moves to discussion concerning the fossil evidence and how they form, the Grand Canyon, the gap theory, what the Bible's genealogies tell us about the age of the earth, why 2 Peter 3:8 is not proof of an old earth, and more.

If the United States is indeed in a space race with China, then we cannot abandon space science. That’s the claim made by Maxwell Zhu and The Planetary Society’s chief of space policy, Casey Dreier, in a recent op-ed in Payload Space. Their piece contrasted the growing ambitions of China’s coming space science program against the draconian cuts proposed by the White House in 2026. The results are stark: where China is pursuing new missions, the United States is abandoning them. Casey and Maxwell explore why this is the case, whether China sees this investment as part of a competition at all, and the structural challenges of integrating space science into a geopolitical context.

If the United States is indeed in a space race with China, why are we abandoning space science programs across the Solar System? This question, posed by guest Maxwell Zhu in a recent op-ed co-authored by The Planetary Society's chief of space policy, reveals the current myopia around human spaceflight and the missing focus on a growing and ambitious new entrant into space science in the 21st century.

NASA’s Perseverance rover has made one of its most intriguing discoveries yet in Jezero Crater. A rock sample called Sapphire Canyon, drilled from the Bright Angel formation, contains unusual chemical and mineral patterns that may be potential biosignatures. We begin with remarks from Morgan Cable, research scientist at NASA’s Jet Propulsion Laboratory and co–deputy principal investigator of the PIXL instrument on Perseverance, in a video released alongside NASA’s September 10, 2025 announcement. Then, host Sarah Al-Ahmed speaks with Joel Hurowitz, associate professor of geosciences at Stony Brook University and deputy principal investigator of the PIXL instrument on Perseverance, who is also the lead author of the new Nature paper detailing the findings. Hurowitz explains how textures nicknamed "poppy seeds" and "leopard spots" connect organic carbon with minerals like vivianite and greigite, and why these could represent some of the most compelling evidence yet for ancient microbial life on Mars. Finally, in this week’s What’s Up, Bruce Betts, The Planetary Society’s chief scientist, joins Sarah to explore earlier moments in the history of Mars exploration when tantalizing hints of life sparked scientific and public excitement.

For decades, Uranus has puzzled scientists. Unlike the other giant planets, Voyager 2’s 1986 flyby suggested the ice giant emitted no excess heat. Now, thanks to new analyses of Voyager data, decades of ground-based and space-based observations, and refined models, scientists have confirmed that Uranus does radiate more heat than it receives from the Sun. Host Sarah Al-Ahmed speaks with atmospheric scientist Michael Roman (Assistant Professor at the Universidad Adolfo Ibáñez in Chile) about his team’s new study showing Uranus emits around 12.5% more energy than it absorbs. Together, they explore what this means for our understanding of Uranus’s atmosphere, its bizarre seasonal cycles, the planet’s violent past, and why these findings strengthen the case for a future flagship mission to the Solar System’s overlooked ice giants.Stick around for What’s Up with Bruce Betts, Planetary Society chief scientist, for a look at Uranus’ newly discovered moon and a new random space fact.

This Day in Legal History: Eisenhower Signs Act Creating NASAOn July 29, 1958, President Dwight D. Eisenhower signed the National Aeronautics and Space Act into law, officially creating NASA. The legislation emerged in response to growing Cold War tensions and the Soviet Union's launch of Sputnik the previous year. It marked a pivotal shift in U.S. federal priorities, establishing a civilian-led space agency to coordinate scientific exploration, aeronautics research, and peaceful uses of space. NASA began operations on October 1, 1958, absorbing the earlier National Advisory Committee for Aeronautics (NACA) and ushering in a new era of government-backed technological ambition.Over the decades, NASA has become a symbol of American innovation, from landing astronauts on the moon to deploying the Hubble Space Telescope. Its work has catalyzed advancements not only in spaceflight, but also in climate science, materials engineering, and telecommunications. The legal framework underpinning NASA reflects a national consensus that science and exploration are critical public goods deserving of federal investment and support.But 67 years later, that consensus is showing strain. Just yesterday, NASA announced that nearly 4,000 employees—about 20% of its workforce—are leaving the agency through the Trump administration's deferred resignation program. This mass exodus follows proposed budget cuts and internal restructuring driven by the Department of Government Efficiency (DOGE), a key player in Trump's effort to slash the federal workforce.The timing couldn't be worse. The administration has called for both sweeping workforce reductions and a significant budget cut of nearly 24% for FY 2026, even as it touts long-term funding increases in the so-called One Big Beautiful Bill Act. Scientists and space advocates, including The Planetary Society, have criticized the inconsistency, calling it a direct threat to American leadership in space. A group of over 300 NASA employees echoed that concern in a public letter this week, denouncing the changes as "rapid and wasteful" and warning that they jeopardize the agency's mission.What began as a proud moment of bipartisan support for science and exploration now faces a political climate where expertise is undervalued and institutional stability is sacrificed for short-term optics.Nearly 4,000 NASA employees opt to leave agency through deferred resignation programIn her latest appeal to the U.S. Supreme Court, Ghislaine Maxwell argues that her 2021 federal sex trafficking conviction should be overturned because it violated a 2007 non-prosecution agreement (NPA) originally struck between Jeffrey Epstein and federal prosecutors in Florida. Maxwell contends that the agreement, which shielded Epstein and his unnamed co-conspirators from federal charges in exchange for his state-level plea, should have also barred her later prosecution in New York. The Justice Department disputes this, saying the NPA applied only to the Southern District of Florida and does not merit Supreme Court review. Maxwell's brief criticizes the DOJ for focusing on Epstein's misconduct rather than the legal scope of the deal, framing the issue as one of government accountability to its promises. The Second Circuit previously upheld her conviction, finding no evidence that the NPA was meant to apply nationally. However, the National Association of Criminal Defense Lawyers filed a brief supporting Maxwell, arguing that even atypical agreements must be honored if made by the government. Political tensions surrounding the Epstein case continue to complicate matters, as Maxwell recently met with Deputy Attorney General Todd Blanche amid renewed scrutiny of the Trump administration's handling of Epstein's prosecution. The Supreme Court is expected to consider whether to hear the case in late September.Ghislaine Maxwell Tells Supreme Court Epstein Deal Shielded HerThe Trump administration has filed a judicial misconduct complaint against Chief U.S. District Judge James Boasberg, accusing him of violating judicial ethics by expressing concerns that the administration might defy court rulings, potentially triggering a constitutional crisis. The complaint centers on comments Boasberg allegedly made during a March meeting of the judiciary's policymaking body, which included Chief Justice John Roberts. The Justice Department argues that these remarks, later echoed in his rulings, undermined judicial impartiality—particularly in a case where Boasberg blocked the deportation of Venezuelan migrants using wartime powers under the Alien Enemies Act. The administration claims Boasberg acted on a political bias when he found probable cause to hold it in criminal contempt for defying his deportation order. The DOJ has asked the D.C. Circuit to reassign the case and refer the complaint to a special investigative panel. Boasberg, appointed to the federal bench by President Obama after an earlier nomination to the D.C. Superior Court by President George W. Bush, has not publicly responded. The D.C. Circuit stayed his contempt finding, and a final ruling is still pending.Trump administration files misconduct complaint against prominent judge Boasberg | ReutersThe U.S. Court of Appeals for the Federal Circuit has extended the suspension of 98-year-old Judge Pauline Newman for another year, citing her continued refusal to undergo a full neuropsychological evaluation to assess her fitness to serve. Despite submitting medical reports from her own experts asserting she is mentally competent, the court concluded that those reports were insufficient and contained inaccuracies, including concerns about memory issues and fainting episodes. Newman's legal team criticized the court's swift decision, arguing that their evidence and arguments were not seriously considered following a recent hearing. Newman, a respected patent law jurist appointed by President Reagan in 1984, is the oldest active federal judge who has not taken senior status and has been a prominent dissenter on the Federal Circuit. The court originally suspended her in 2023 after Chief Judge Kimberly Moore raised concerns about her cognitive and physical condition. Newman sued over the suspension, but her case was dismissed; it is now under review by a separate federal appeals court. The latest ruling reaffirms the court's insistence on comprehensive testing before any reconsideration of her judicial role.US appeals court extends suspension of 98-year-old judge in fitness probe | ReutersDonald Trump has asked a federal court to expedite a deposition of Rupert Murdoch in his $10 billion defamation lawsuit against the Wall Street Journal over a July 17 article linking him to Jeffrey Epstein. The article claimed Trump sent Epstein a 2003 birthday greeting that included a suggestive drawing and cryptic references to shared secrets—allegations Trump calls fabricated. In a court filing, Trump's lawyers said he informed Murdoch before publication that the letter was fake, and Murdoch allegedly responded that he would “take care of it,” which they argue demonstrates actual malice—a necessary legal threshold in defamation cases involving public figures. Trump's team is seeking Murdoch's testimony within 15 days, and Judge Darrin Gayles has ordered Murdoch to respond by August 4. The article's release has intensified political scrutiny of Trump's handling of the Epstein investigation. Legal analysts note Trump faces an uphill battle given the stringent standards for proving defamation, especially against media outlets. Dow Jones, which publishes the Journal, said it stands by its reporting and intends to vigorously defend the case.Trump asks for swift deposition of Murdoch in Epstein defamation case | ReutersMy column for Bloomberg this week argues that the latest shift in federal tax law—the move from the global intangible low-taxed income (GILTI) regime to the net controlled foreign corporation tested income (NCTI) system—should push states to reassess their habitual conformity to the Internal Revenue Code. NCTI expands the scope of taxable foreign income for U.S. multinationals, reflecting a broader federal effort to combat base erosion and bolster global competitiveness. But when states automatically conform to these changes—especially through rolling conformity—they risk inheriting complex, federally motivated rules that don't align with their economic interests or legal authority.Rolling conformity is a mechanism by which a state automatically updates its tax code to reflect changes in the federal Internal Revenue Code as they occur, without requiring separate legislative action. While rolling conformity can reduce administrative friction, it's increasingly problematic in an era of aggressive and frequent federal tax rewrites. States adopting NCTI may find themselves without key federal mechanisms like foreign tax credits or Section 250 deductions, exposing them to potential legal challenges over extraterritorial taxation and apportionment. These lawsuits could be expensive, prolonged, and ultimately hinge on issues that federal tax policy has already moved past. I argue that states need to move beyond passive conformity and take an intentional, sovereign approach to tax policy—reviewing conformity statutes now, decoupling where necessary, and preparing to defend their fiscal independence in the face of Washington's rapid policy swings.Trump Tax Law Should Spur States to Split From Federal ‘Pendulum' This is a public episode.

Recorded at the 2025 Humans to the Moon and Mars Summit (H2M2) in Washington, D.C., this episode features two powerful conversations about the future of human space exploration. Hosted by Mat Kaplan, senior communications adviser at The Planetary Society, these panel discussions explore the scientific and diplomatic foundations guiding humanity’s journey beyond Earth. The first panel, Space Science: A Vital National Interest, features James Green, former NASA chief scientist and chair of the Explore Mars advisory board, James Garvin, chief scientist at NASA Goddard Space Flight Center, Britney Schmidt, astrobiologist and associate professor at Cornell University, and John Mather, Nobel Prize–winning astrophysicist and senior scientist for the James Webb Space Telescope. They discuss how space science drives innovation, strengthens U.S. national priorities, and deepens our understanding of the universe, especially in the face of proposed funding cuts. In the second panel, Artemis Accords: International Collaboration in Deep Space, Mike Gold of Redwire, Marc Jochemich of the German Aerospace Center (DLR), Adnan Mohammad Alrais of the Mohammed bin Rashid Space Centre, and Sohair Salam Saber of The Hague Institute for Global Justice explore how diplomacy and shared values are shaping global participation in lunar exploration. The conversation also highlights the Washington Compact, an effort to bring shared values and responsible behavior in space to commercial companies and other non-governmental organizations. We wrap up the show with a new What’s Up segment with Bruce Betts, where we talk about what could happen if the Gateway lunar space station is canceled, and how that would impact humanity’s dreams for Mars.

The OSIRIS-APEX mission, an extension of the wildly successful OSIRIS-REx mission, is set to rendezvous with Asteroid 9942 Apophis in April 2029. This mission takes full advantage of the OSIRIS-REx spacecraft, which still has plenty of fuel and is totally healthy after delivering samples from Asteroid Bennu to Earth on 24 September, 2023. OSIRIS-APEX will closely observe Apophis as the asteroid makes a remarkably close flyby of Earth, coming within 32,000 kilometers (20,000 miles)  – closer than some Earth-orbiting satellites. The mission's primary objectives are to study how Earth's gravitational pull affects the orbit of Apophis, its spin, and surface features. However, the mission is in peril. The proposed Presidential Budget Request for Fiscal Year 2026 budget calls for the cancellation of OSIRIS-APEX, despite its low cost and the scientific value it offers as an extended mission using an already existing and proven spacecraft. On this episode of Talking Space, we're joined by Dr. Dani Mendoza DellaGiustina, Principal Investigator for the OSIRIS-APEX mission and Assistant Professor at the University of Arizona's Lunar and Planetary Laboratory. We'll delve into the mission's goals, the reasons given behind its potential cancellation in the 2026 NASA Budget, and the options available should the 2026 budget be approved by Congress, a budget that cancels this ambitious mission.

John and I welcomed Casey Dreier from The Planetary Society to the program to go over the proposed NASA space and science budget cuts and project eliminations. Casey suspected the direction for the cuts originated out of OMB without much space guidance or thought. He identified several of the projects and programs identified for either a budget cut such as the Nancy Grace Roman Space Telescope to the New Horizons and Venus missions being totally eliminated. Casey also talked about the bleak future for SLS and the Gateway for their demise post Artemis 3. Casey talked about their being a shift to commercial Moon missions but with little detail and clarity. Cislunar development, cargo and resupply to the ISS, the future for the private space stations, Mars and EDL for Mars plus demos all were part of our discussion. In Part 2, John talked about the robotic missions including existing missions plus the future missions, all of course depending on robots. Casey worked in commentary about cuts and changes for both JPL and Goddard, two very important and key Nasa centers. Before concluding the program, our guest was asked about the impact of the layoffs for NASA scientists and engineers. Casey suggested they would have an uncertain future ahead of them as their might not be abundant job opportunities for these important skills.

What a wild week it's been for NASA. With drastic budget cuts looming—pending any action by Congress—then comes the sudden and unexpected pulling of Jared Isaacman for the role of NASA Administrator, with no replacement named. Then came the very public split between President Trump and Elon Musk, and a flurry of furious Twitter/X and Truth Social postings, aimed at each other with razor-sharp edges. And finally, the proposed and drastic cuts to NASA outreach and education budgets, slimming them to nearly nothing. These are strange and concerning times for America's space agency, a premier global brand and icon of peaceful American prowess. We turned to Casey Dreier, the Chief of Space Policy for The Planetary Society, who has been quite vocal in his concern, for context. These are critical times for spaceflight, so you won't want to miss this episode!Headlines Trump and Musk "Bromance" Ends: Rod Pyle and Tariq Malik discuss the public falling out between Donald Trump and Elon Musk, which included Trump's threats to cancel SpaceX contracts and Musk's counter-accusations regarding the Jeffrey Epstein files. Commercial Crew Program and Boeing's Starliner: Tariq Malik highlights the critical role of SpaceX's Dragon in NASA's commercial crew program, especially given Boeing's Starliner delays, making NASA dependent on SpaceX for U.S. independent access to space. Japanese ispace Lunar Lander Failure: Rod Pyle and Tariq Malik discuss the second failed attempt by the Japanese company ispace to land its Hakuto-R lunar lander on the moon, losing the European Space Agency's mini-rover, called Tenacious, in the process. Speculation on SpaceX Nationalization: The hosts discuss online speculation, including from Steve Bannon, about the possibility of the U.S. government nationalizing SpaceX, and Elon Musk's subsequent de-escalation. LAUNCH Act: Rod Pyle introduces the bipartisan LAUNCH Act, aimed at streamlining licensing for commercial space companies to encourage more rocket launches with faster approvals.

PREVIEW: Colleague Casey Dreier of the Planetary Society comments on the last of the NASA hardware extant for a moon landing mission. More later. 1958

The White House has released its Fiscal Year 2026 congressional budget justification for NASA, and the implications are staggering. If enacted, this proposal would slash NASA’s science program funding by nearly half, cancel dozens of active and upcoming missions, and reduce the agency’s workforce by one-third. Sarah Al-Ahmed is joined by Jack Kiraly, The Planetary Society’s director of government relations, to examine what’s in the nearly 500-page document, what it means for the future of space science and exploration, and how advocates can still act to save NASA science. Then, in What’s Up, Planetary Society Chief Scientist Bruce Betts shares insights on China’s newly launched asteroid sample return mission, Tianwen-2. The spacecraft will rendezvous with near-Earth asteroid 469219 Kamoʻoalewa, offering new scientific opportunities amidst a moment of global uncertainty in space exploration.

NASA’s science programs are facing the largest proposed budget cut in more than 40 years. This staggering 47%reduction could cancel missions, waste billions in U.S. taxpayer investments, and unravel decades of discovery. In this episode of Planetary Radio, host Sarah Al-Ahmed is joined by Casey Dreier, The Planetary Society’s Chief of Space Policy, and Jack Kiraly, Director of Government Relations. Together, they break down what the “passback” stage of the federal budget process means for NASA, which missions and programs are in jeopardy, and how you can help push back. Later in the show, Chief Scientist Bruce Betts joins us for a reflective What’s Up as we explore the science that could be lost and why it still deserves to be saved.

For decades, scientists hypothesized that Mars’ reddish color came from hematite, an iron oxide thought to have formed through dry oxidation after Mars lost its water. But new research suggests the story is more complex—and more watery—than we once imagined. In this episode, planetary scientist Adomas (Adam) Valantinas from Brown University joins host Sarah Al-Ahmed to discuss his team’s discovery that Mars’ iconic red dust is likely dominated not by hematite but by a hydrated mineral called ferrihydrite. This subtle but significant shift in understanding could reshape what we know about Mars’ climate history and its potential for past habitability. Then, Sarah and Bruce Betts, Planetary Society chief scientist, revisit one of the most famous Martian discoveries: Opportunity’s hematite-rich “blueberries,” which also told a compelling story about water on the Red Planet.

Join Sarah Al-Ahmed and Casey Dreier for a special live recording of Planetary Radio at the Johns Hopkins University Bloomberg Center in Washington, D.C., immediately following The Planetary Society’s Day of Action. In this episode, we explore the complex geopolitical landscape NASA faces as it works toward returning humans to the Moon and exploring other worlds. With growing influence from commercial space companies, potential budget cuts, and changes in committee leadership, this pivotal moment in space exploration is shaping NASA’s future. We’re joined by Bill Nye (CEO, The Planetary Society), Nancy Chabot (Chief Scientist, Johns Hopkins Applied Physics Laboratory), Rep. George Whitesides (Representative, CA-27), Rep. Judy Chu (Co-chair, Congressional Planetary Science Caucus, Representative, CA-28), and Antonio Peronace (Chief Executive, Space for Humanity). Together, we explore how evolving national priorities, key lawmakers, and the rapid growth of the commercial space sector could reshape U.S. space policy, potentially redefining the motivations that have driven space exploration since the Apollo era.

The Apollo program put humans on the Moon, but behind that historic achievement were engineers whose stories have gone largely untold. In this episode, “LA Made: The Other Moonshot” host Joanne Higgins joins Planetary Radio to share the powerful history of Charlie Cheatham, Nate LeVert, and Shelby Jacobs, three Black engineers in Los Angeles who helped make Apollo possible while navigating racism and exclusion. We discuss how their technical brilliance shaped the space program, why their stories were left out of the history books, and how telling them now can help create a more equitable space community for the future. Plus, Casey Dreier checks in from Washington, D.C., during The Planetary Society’s Day of Action, where advocates from across the U.S. gathered to support NASA science. And in What’s Up, Bruce Betts and Sarah explore the Apollo-era technologies still in use today.
