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.

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.

Bill Gowan, Tuesday, 10-28-25Quick Summary:The main focus of the discussion was Bill's experience participating in The Planetary Society's advocacy efforts on Capitol Hill, where he and other volunteers met with congressional representatives to advocate for increased funding for NASA's science programs, which faces a proposed 47% budget cut in 2026.Detailed SummaryDavid Livingston hosted a special early Tuesday space show program featuring Bill Gowan, a retired electrical and systems engineer with experience in medical comms and aerospace. Bill discussed a recent citizens lobbying event in D.C. where 300 people met with their representatives to advocate for saving NASA science, which faces a proposed 47% budget cut in the 2026 NASA budget. The discussion highlighted how NASA science benefits American society through economic, medical, and technological advancements, while also addressing concerns about NASA employee reductions, with 20% of employees expected to leave by year-end. Bill was one of the 300 participating in the advocacy event.Bill explained that the 20% net figure for employee retirements and departures to private industry includes normal attrition and is considered a legitimate concern. He clarified that the advocacy work he and others were involved in was not lobbying, as it was done on a volunteer basis without payment. Bill described his decision to participate in the October advocacy event, which involved 19 other organizations, despite the success of a similar effort in March, due to the ongoing need to encourage Congress to do more for NASA and address the organization's weakening foundation.Bill described a two-day training event organized by The Planetary Society for over 300 participants, including meetings with congressional representatives. The training covered NASA's budget, with President Biden requesting $3.9 billion for NASA science, while the Senate proposed $7.3 billion and the House $6 billion, though with a “not less than” clause. Bill explained that participants met with their senators' offices and representatives, with the logistics managed by a third party to ensure efficient scheduling.Bill and David discussed strategies for advocating for NASA's space and science budget before Congress. They highlighted the importance of preparing clear messages, leveraging public support, and emphasizing the economic benefits of NASA's science missions. Bill shared his experience with his own North Carolina delegation, where they met with seven members, including some first-time advocates. They emphasized the need to prioritize space science, referencing China's increased investment in space exploration, and highlighted the return on investment for NASA's science programs. Bill also mentioned the case of Christina Cook, a North Carolina native who will be the first woman to walk on the moon, to underscore the state's connection to NASA's missions.Bill discussed his experiences with meetings, noting that they lasted between 15 and 30 minutes. He shared that he had not seen individuals using meetings to advocate for personal issues, but he believed it would be permissible as long as the person was clear they were speaking as a citizen, not for any organization. Bill also mentioned meeting with Representative Fushi's staffer, who was knowledgeable and supportive of NASA funding. Dr. Ajay Kothari inquired about the responses from Congress members, and Bill explained that both his representative and Senator Fushi were supportive of NASA funding. They briefly discussed the Senate's $7.3 billion NASA science budget and how it relates to the $10 billion added by Senator Cruz, which Bill clarified was part of a reconciliation bill outside the normal appropriation process.Bill shared his previous experience participating in NASA advocacy meetings on Capitol Hill, noting that congressional staff generally receive space advocacy messages positively but express concerns about the 47% budget cut proposed by the administration. He explained that while there's no significant difference in reception between Democratic and Republican-controlled White Houses, the current proposal faces resistance due to the large percentage cut being implemented in one year. The meetings, which involve approximately 300 advocates, are organized by Casey Dreyer and Jack Corrali, with participants completing feedback forms after each meeting to help improve future advocacy efforts.Special thanks to our sponsors:Northrup Grumman, American Institute of Aeronautics and Astronautics, Helix Space in Luxembourg, Celestis Memorial Spaceflights, Astrox Corporation, Dr. Haym Benaroya of Rutgers University, The Space Settlement Progress Blog by John Jossy, The Atlantis Project, and Artless EntertainmentOur Toll Free Line for Live Broadcasts: 1-866-687-7223 (Not in service at this time)For real time program participation, email Dr. Space at: drspace@thespaceshow.com for instructions and access.The Space Show is a non-profit 501C3 through its parent, One Giant Leap Foundation, Inc.

I denne RumSnak ser vi nærmere på det spritnye Vera C. Rubin Observatory, et stort teleskop i Chile, der for ganske nylig er begyndt at tage billeder, og som de næste ti år skal tage massevis af billeder at den sydlige himmel. Der er mange videnskabelige mål med Vera Rubin – man vil både fotografere milliarder af galakser og samle data der kan hjælpe forskerne med at forstå mørkt stof, men observatoriet skal også kortlægge små objekter her i vores Solsystem og være med til at kortlægge Mælkevejen. Vi har besøg af Christa Gall fra Niels Bohr Institutet, som kan fortælle meget mere om hvad Vera Rubin skal bruges til. Vi skal dog også have et par aktuelle nyheder, denne gang blandt andet om en grovædende planet og spændende molekyler på en af Saturns måner. Lyt med

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.

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.

Casey Dreyer, Director of Space Policy at the Planetary Society, joined us in our Space Show Zoom room to discuss the proposed 2026 NASA budget. He criticized the budget as unprecedented, “unstrategic,” and damaging—highlighting a historic 25% cut that could cancel numerous missions and projects. Casey stressed that the budget breaks the Artemis consensus, cuts scientific research, and threatens NASA's workforce. He dismissed the possibility of significant internal savings, arguing that most mission costs are tied to personnel and would require major structural reform. Casey suggested the budget proposal reflected a broader shift in U.S. priorities away from science and questioned the lack of clear space policy leadership from the White House. He attributed the budget's anti-science stance more to Rust Vought of OMB than Elon Musk and noted that NASA was excluded from key budget conversations due to the absence of a confirmed administrator.The group discussed how budget cuts affect commercial space activity and NASA's ability to support it. Casey emphasized the importance of long-term commitments to programs like Artemis to sustain a commercial space economy. While some companies remain successful, many are shifting focus toward defense contracts due to market and funding uncertainties. Zoom participant Phil proposed reframing NASA's mission in terms of national competition with China to align with current political priorities. Casey agreed that emphasizing competition with China might be effective but warned against undermining NASA's nonpartisan image. He noted that while public support exists for NASA's science missions—such as climate observation and planetary defense—human spaceflight to the Moon or Mars is less popular.Casey also addressed potential solutions, including advocating for a supplemental budget or stronger congressional resistance. Zoom listener John H suggested a continuing resolution (CR) may be the most likely outcome, given Senate voting requirements and ongoing reconciliation bill discussions. Casey explained that while a CR might appear manageable, the Office of Management and Budget (OMB) could impose harmful restrictions through aggressive executive interpretation.In discussing congressional prospects, Casey was skeptical about swift action due to a narrow Republican majority and competing legislative priorities. He warned that inaction could have severe consequences and reiterated the importance of public and congressional engagement.The conversation turned to the role of the National Space Council and the implications of JD Vance's leadership. Casey expressed concerns about the lack of strategic guidance and the administration's failure to advocate its own space policy vision. He emphasized the need for policy alternatives to reduce reliance on a single contractor—namely SpaceX—and criticized the current vulnerability of programs like the Space Launch System (SLS).When asked about China's potential to reach the Moon first, Casey speculated that it could lead to a symbolic loss for the U.S., though the political response remains uncertain. He stressed that the administration's lack of public advocacy for NASA's goals is damaging and that human spaceflight's popularity depends heavily on its visibility and perceived success.In closing, Casey described the Planetary Society's advocacy efforts, highlighting their independent and aggressive campaign against the proposed cuts. He reaffirmed the importance of preserving NASA's nonpartisan reputation while pushing for restored funding. He also mentioned an upcoming podcast episode on the NASA budget featuring guests from the Commercial Spaceflight Federation (CSF) and the American Geophysical Union (AGU). The group agreed to remain engaged and offer support to help reverse the budget cuts.Listeners and viewers, much more was discussed during the 1 hour 16 minutes with Casey so be sure to either watch all of the video or listen to all of the audio. We were joined in the Zoom room by Space Show Advisory Board members Bill Gowan, John Jossy, John Hunt, A.J. Kothari, and Dr. Phil Swan. Many more questions were asked of Casey including my end of the program for Casey and/or the Planetary Society to create an alternate budget to use in working to move away from the proposed skinny budget. Such an alternate budget by those who know and are familiar with space, science and NASA would also be a terrific and relevant handout to members of congress, staffers and even the president and his office. I hope Casey and his associates follow through on this suggestion.

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. Senate Reconciliation Bill: Tariq Malik and Rod Pyle discuss Senator Ted Cruz's Senate reconciliation bill, which proposes to restore funding for the Space Launch System (SLS), increase NASA's budget by $10 billion, and fund Artemis 4 and 5, missions previously targeted for alternate architectures. 60th Anniversary of First U.S. Spacewalk: The hosts commemorate Ed White's historic spacewalk during the Gemini 4 mission in 1965 and discuss anecdotes and lingering questions surrounding the event. Definition of an Astronaut/Spacewalker Debate: Rod Pyle and Tariq Malik briefly touch on the ongoing debate about what defines an "astronaut" or "spacewalker," given varying definitions and commercial spaceflight.

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.

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.
