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.

The Space Show presents Phil Swan, Friday, 10-24-25Quick recapThe program focused on economic and technological aspects of space exploration, particularly Mars voyages, with Phil Swan presenting his analysis of kinetic energy costs and the need for long-term strategic planning. The discussion covered various propulsion technologies, cost considerations for different rocket systems, and the potential for in-situ resource utilization on Mars. The group explored concepts like mass drivers, lunar industries, and the economic viability of Mars cyclers, while emphasizing the importance of developing cost-effective solutions for human space travel and long-term settlement on Mars and the Moon.Detailed Summary: Phil Swan, the lead principal engineer for the Atlantis project, presented his recent Mars Society Conference talk, focusing on the economic aspects of kinetic energy for Mars voyages. He emphasized the need for a long-term strategy that makes Mars valuable to humanity, beyond just the initial journey. The discussion touched on the historical reluctance to use terms like “colonization” due to negative connotations, and Phil noted the importance of understanding the economics of kinetic energy in space travel. The program also included updates on podcast availability and ways to support the Space Show.Phil discussed the importance of developing a sophisticated space strategy that combines high-level merit with institutional capacity to support it. He compared humanity's expansion across Earth to potential space exploration, noting that exponential thinking is necessary to set realistic goals and expectations for space travel. Phil emphasized the need to apply exponential thinking to space problems rather than relying on linear thinking, as this approach could lead to more accurate timelines for reaching celestial destinations like the Moon and Mars.Phil referenced the technological advancements required to reach the Moon and Mars, highlighting the Lunar Orbit Rendezvous as a pivotal innovation. He emphasized the need for new technologies to enable human settlement on Mars and addressed the challenge of long-term value recognition for such endeavors. Our guest proposed a staged approach to Mars exploration, outlining key stages like “Boots on Mars,” “Research Outpost,” “Expansionist Drive,” and “Keystone Industries,” each with its value proposition and enablers. He concluded by identifying the high cost of interplanetary transportation as a significant barrier to progress, emphasizing the need for cost-effective solutions to make Mars exploration feasible.The group discussed the concept of Mars cyclers, with Phil explaining that they would serve as infrastructure for repeated Mars travel, though questions remained about their economic viability and technical feasibility. They explored the idea of self-sustaining biospheres on Mars cyclers and Mars bases, with Phil noting that technology would play a crucial role in maintaining these environments. The discussion concluded with Phil addressing the question of Mars's independence, comparing it to the interdependence between continents and suggesting that Mars would eventually become more self-supporting over time, though it would initially rely on supplies from Earth.We also discussed the need for more advanced propulsion technologies beyond chemical rockets, such as nuclear plasma or fusion rockets, to enable more efficient space travel. Phil highlighted the challenge of securing funding for long-term space exploration projects compared to immediate investments like Starlink, attributing this to society's short-term focus. Marshall and Phil agreed that governments might be better at making long-term investments, while David noted cultural differences in budgeting practices, particularly between the U.S. and China. Phil suggested that future space missions could serve as a test to compare different economic and political systems, similar to the Cold War moon race, which he argued was won by the American free-market system. John Hunt observed that the lack of competition from the Russian space program in the 1970s led to a reduction in space technology development in the U.S.Our guest presented a slide showing the delta V requirements for various destinations in the solar system, emphasizing the need for cheaper and faster transportation methods. He discussed the potential for using aerobraking and the economic benefits of lunar industries producing products for low Earth orbit. John Jossy suggested considering near-Earth asteroids for mining, which Phil acknowledged as a viable option with lower delta V requirements. The group also touched on the economics of low Earth orbit and the potential for lunar materials to be used in space industries.Phil explained the concept of delta-v and air braking, noting that while aero braking reduces the need for fuel, some mass is still required for the heat shield and other landing equipment. He discussed a paper titled “Cost vs. Delta V” that outlines the methodology for converting air braking delta-v into an equivalent rocket-based delta-v. Phil then presented a graph illustrating the relationship between delta-v and cost per kilogram for various missions, highlighting that costs scale exponentially with delta-v requirements. He noted that reusable rockets and infrastructure-based solutions could potentially reduce costs and provided examples of how different launch systems performed compared to the cost curve.The group discussed the cost-effectiveness of different rocket technologies, particularly comparing the Space Launch System (SLS) to Falcon Heavy. Phil noted that while Falcon Heavy was slightly more cost-competitive for some missions, SLS was still a viable technology that offered good value for its Delta V capabilities. John Hunt highlighted the issue of low production quantities for SLS, which limited cost savings from experience curve effects. The discussion concluded with an examination of Mars mission costs, with Phil presenting estimates for sending humans to Mars, including the cost of crew, provisions, and life support systems.Phil presented a detailed analysis of Mars mission costs, highlighting that a round-trip mission would cost $38 trillion, but could be reduced to $2.7 trillion through in-situ resource utilization and a Mars propellant plant. The discussion clarified that the Europa Clipper mission was launched by Falcon Heavy, not SLS, and Phil agreed to review the cost numbers later. Phil also explained the energy efficiency advantages of mass drivers compared to rockets, suggesting that Mars should consider implementing mass drivers for future space operations.Phil then presented a detailed analysis of mass drivers, discussing their potential for Mars and Earth-based applications. He explained the physics and economics of mass drivers, highlighting their cost advantages over rockets for Mars missions. The group discussed technical challenges, including G-forces and atmospheric entry, with Phil addressing concerns about safety zones and aiming. The conversation ended with a brief discussion on human transportation to Mars, noting the need for further exploration of options beyond cargo transport.Our guest discussed the challenges of improving human space travel to Mars, focusing on reducing costs and enhancing comfort and safety. He suggested increasing the mass budget, improving ecosystems, and using more efficient propulsion methods like mass drivers. David inquired about nuclear propulsion, but Phil explained that it may not be practical due to the weight of radiators compared to solar panels. They also discussed the limitations of current mass driver technologies, such as SpinLaunch, which can only replace the first stage of a rocket and cannot achieve the necessary delta V for Mars travel. Phil emphasized the need for a 1,000-fold cost reduction to enable long-term human settlement on Mars and the Moon.As we were moving to the end of the program, Phil discussed the challenges and inefficiencies of using aircraft carrier electromagnetic catapults for launching rockets into space, explaining that such systems would be too expensive and impractical compared to traditional rockets. He also explored the concept of linear motor launchers for space travel, noting that while they could potentially compete with rockets for long-distance missions like Mars travel, they are not cost-effective for low Earth orbit missions. The discussion highlighted the importance of developing a long-term strategy for lunar and Martian exploration, as well as the need for better institutional and public evaluation of complex space travel ideas.Audio is posted at www.thespaceshow.com for this date and Substack, doctorspace.substack.com.

Dave also addressed the use of AI in Arkisys operations—be sure to catch his insights on that topic. Before concluding, he shared updates on internships and future hiring plans. Earlier in the conversation, he enthusiastically described Arkisys's mentorship of student teams focused on in-space construction, noting a significant year-over-year increase in participation, underscoring growing interest in this sector.

The Space Show welcomed award-winning author and former Caltech radio astronomer Marcus Chown to discuss his latest book, A Crack in Everything: How Black Holes Came in from the Cold and Took Cosmic Center Stage. Chown shared his journey from early inspiration—thanks to a childhood astronomy book and the moon landing—to his current career as a science writer/journalist. He also noted the success of his previous book, The Ascent of Gravity, named the Sunday Times Science Book of the Year.Chown traced the transformation of black holes from theoretical curiosities to essential cosmic players. He described the 1971 discovery of the first black hole in the Cygnus X-1 system and explained how supermassive black holes were surprisingly identified before stellar-mass ones, thanks to observations by the Hubble Space Telescope. He clarified that while black holes themselves emit no light, matter falling into them creates bright emissions.Chown highlighted the overlooked contributions of women in astronomy, especially Louise Webster, co-discoverer of black holes. He emphasized black holes' vital role in galaxy formation and the intriguing theory that their presence may influence the emergence of life.Chown detailed how light elements formed in the Big Bang, while heavier ones like uranium and thorium emerged in supernovae. The 2017 detection of gravitational waves from neutron star mergers revealed the origin of precious metals like gold and platinum, solving a long-standing mystery. He also explained that gamma-ray bursts, once detected by military satellites, are linked to these cataclysmic events. This was in response to a question by Dr. Kothari. In addition, his discussing regarding uranium, thorium, and plutonium helped to explain that only specific isotopes are fissile due to nuclear forces. These elements contribute to Earth's heat and helium production. He praised physicist Lise Meitner, co-discoverer of nuclear fission and developer of the liquid drop model, who was nominated 49 times for the Nobel Prize but never awarded.Chown addressed how James Webb Space Telescope findings—such as unexpectedly bright early galaxies and potential newborn supermassive black holes—challenge current galaxy formation theories. He explored speculative ideas, including advanced civilizations possibly harnessing black hole energy, and the elusive role of dark matter in cosmic structure.I had Marcus if he had any concerns about what may be a U.S. pull back from science and engineering for budgetary reasons. I wanted to know if thought there were other players that might step in and fill the void left by the U.S. were the pull back to happen. Marcus expressed concern over a potential U.S. retreat from scientific leadership, emphasizing the difficulty other nations would face in filling that gap. He reflected on Roy Kerr's 1963 rotating black hole solution, overshadowed at the time by quasar discoveries. Looking ahead, he encouraged continued exploration and proposed future discussions on dark energy.I closed by reminding listeners that The Space Show is a listener-supported 501(c)(3) nonprofit and encouraged donations to help sustain the program.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: 1-866-687-7223For real time program participation, email Dr. Space at: drspace@thespaceshow.comThe Space Show is a non-profit 501C3 through its parent, One Giant Leap Foundation, Inc.

This was a special 2-hour, 16-minute Zoom program.On The Space Show website, the program is available in the audio-only format. Both video and audio are available on this Substack page.Our discussion focused on the development and evolution of GPS and the recently declassified PARCAE satellite technology. We explored their origins, technical challenges, historical context, and how they interconnected with agencies like the NRO, NRL, and broader advances in computing and satellite technologies. The conversation covered early proposals, the declassification process, and the crucial role of timekeeping, atomic clocks, and Einstein's relativity in enabling this groundbreaking work. Our guests also shared perspectives on future applications, innovation “back in the day,” system resilience, and the shift from strategic to tactical intelligence using satellites like GRAB and POPPY.After introductions, Richard provided an in-depth overview of our special guests and the PARCAE project. Lee began by referencing a 1957 Naval Research Laboratory (NRL) document that proposed two major satellite programs, one of which was PARCAE. He also shared that he is currently writing a book on the evolution of these systems, including GRAB, POPPY, and PARCAE.We examined how GPS and PARCAE—two closely linked programs—emerged. GPS, which began development in the late 1950s, utilized passive ranging for uniform accuracy across satellite constellations. PARCAE evolved from early reconnaissance satellites and focused on collecting radar signals globally, especially from the Soviet Union. GPS's ability to provide accurate geolocation greatly enhanced PARCAE's capabilities. Lee emphasized the importance of 3D mapping and global time synchronization in improving satellite positioning accuracy. We also discussed the difficulties of orbital prediction, relativistic corrections, and the eventual declassification of GPS for civilian use. Note what our guests said about getting so much data that they were overwhelmed and the early computers could not really handle.On the military front, we addressed how GPS was used for targeting and precision strikes. In response to a listener question, Lee explained that as early as 1966, the goal was to accurately know the location of both the user and the target to direct weapons effectively. The challenges included creating precise maps and compensating for Earth's motion. The GPS system reached full operational capability in 1995, evolving from 15-foot accuracy in 1977 to today's much finer resolution. The conversation also covered the complexity of GPS—its integration across organizations, multiple technologies, and the development of similar systems by other nations. Our guests discussed the foundational work of pioneers like Roger Easton (Richard's father), John Foster, Alexander Flax, Alan Berman, John McLucas, David Packard, and others.Later, a listener asked the guests to share their educational and career backgrounds. Lee spoke about earning his bachelor's in electrical engineering from Penn State, where he gained early experience in transistor design. His career took off when he was recruited by Singer and later the NRL after his work during the Cuban Missile Crisis. Peter, an EE graduate from Purdue, also found his way to NRL. Richard shared his own background as well. All three emphasized the importance of self-education and the freedom they had to explore ideas across disciplines—something they felt was essential to their success.Peter reflected on GPS evolution and expressed regret about abandoning UHF transmissions, which might have enhanced performance in forested areas. Lee emphasized the need for cost reduction in future GPS upgrades and the importance of cross-disciplinary exposure for young minds. Peter recounted how Roger Easton proposed passive ranging and how Alan Berman's expertise in atomic clocks was instrumental in advancing GPS. Peter also shared insights into clock accuracy improvements for space use and how he initially doubted such improvements were possible—until he realized it required different physics principles. When asked about using GPS on the Moon and Mars, both Peter and Lee explained the limitations. While GPS signals can be detected on the Moon, a local positioning system might be more practical. On Mars, environmental challenges like dust storms complicate signal transmission. Later, Peter discussed the Clementine mission, which mapped the Moon using cameras initially developed for the Strategic Defense Initiative. Lee noted how Clementine's data later supported encryption and high-speed networks in education and defense. They also addressed early GPS launches—Peter developed a cost-effective launch solution using surplus ICBMs, and Lee praised Peter's innovative "bow and arrow" launch method.Peter and Lee described the technical precision required for GPS accuracy, including clock modulation and carrier frequency synchronization. Applications like tectonic plate monitoring were among the early uses. Concerns were raised about GPS vulnerability in nuclear environments and its role in nuclear targeting. Peter expressed alarm over the potential for nations like North Korea to disrupt GPS via high-altitude nuclear detonations. We ended with a discussion on hypersonic weapons and the challenges of tracking them due to plasma interference with electromagnetic signals.The program concluded with a listener question about whether today's education system can produce the kind of innovation seen in early satellite development. All three guests expressed concerns, citing the need for more emphasis on freedom to explore and pursue self-education. Don't miss all of their comments on this important question.Listeners, feel free to post comments on this program and for our guests on both TSS blog page but also using the comments on our Substack page, doctorspace.substack.com.The audio only version of this program is here:Space Show Upcoming Programs: roadcast 4383: ZOOM: Marcus Chown, UK author | Sunday 08 Jun 2025 1200PM PTGuests: Marcus ChownMarcus talks about his new book, "THE ASCENT OF GRAVITY."

My initial question to guest Jim Meigs focused on the ongoing conflict between Elon Musk and Donald Trump and its potential implications for U.S. space policy and programs, particularly NASA's future leadership and priorities. Together with our guest, listeners explored the challenges and uncertainties facing NASA's human spaceflight efforts, including budget constraints, shifting mission timelines, and the increasing need for private sector involvement. We also discussed possible alternatives for advancing U.S. space exploration, such as enhanced collaboration between commercial space companies, all within the context of the Musk-Trump feud. Challenges to science and robotic missions were also talked about.Moving forward, I invited Jim to discuss his April paper, U.S. Space Policy: The Next Frontier, which is linked on our blog. In doing so, he highlighted the unexpected change in NASA's leadership. One potential nominee for NASA Administrator is Gen. Steven Kwast, a past guest on The Space Show. I briefly summarized his previous appearances, noting his strong advocacy for both national security space and commercial space development. Jim also commented extensively on Jared Isaacman, who was widely expected to be nominated as NASA Administrator before his nomination was recently withdrawn. Listeners had much to say on this topic.Jim raised concerns about the political risks of SpaceX's current dominance in space policy. He warned that a future Democratic administration could seek to limit NASA's collaboration with Elon Musk, underlining the importance of maintaining multiple commercial partners to mitigate both political and operational vulnerabilities. Jim advocated for NASA to concentrate on basic research while outsourcing launch capabilities to private industry. He also addressed the need for FAA reform in both aviation and space sectors and urged NASA to adopt a more entrepreneurial mindset—though he acknowledged that congressional resistance could make such change difficult.Listeners, along with Jim, had much to say about the withdrawal of Isaacman's nomination so that topic was a frequent one on this program. Jim explained that although Isaacman enjoyed Senate support, there was a lack of clarity as of the time of this program as to why his nomination was withdrawn. There was much speculation on this issue mentioned on this program. Jim further pointed out that delays in confirming a new NASA administrator—possibly stretching over several months due to the power transition and Senate confirmation process—could be costly for NASA and the broader space community. There was some debate over the authority of the current acting administrator, with Jim suggesting she was exercising a cautious and diplomatic approach in her interim role.We touched on other broader NASA priorities, particularly the tension between lunar and Martian mission planning. Jim commented on the challenges of integrating the Starship HLS with the SLS for Artemis missions. Both our guest and listeners expressed skepticism about the proposed timelines. Budget concerns, the fate of ongoing programs, and NASA's long-term direction were also part of the conversation.Jim left the program at the bottom of the hour for a hard break. However, Zoom participants and livestream listeners continued the discussion in an open-format session, covering additional points and expanding on earlier topics raised during Jim's appearance.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 EntertainmentFor real time program participation, email Dr. Space at: drspace@thespaceshow.comThe Space Show is a non-profit 501C3 through its parent, One Giant Leap Foundation, Inc.

John and I welcomed Casey Dreier from The Planetary Society to the program to discuss the proposed NASA space and science budget cuts and the elimination of several key projects. Casey suggested that the direction for these cuts likely originated from the Office of Management and Budget (OMB), with minimal input or guidance from the space policy experts.He highlighted several affected programs, including significant budget reductions to the Nancy Grace Roman Space Telescope, and the potential termination of the New Horizons and Venus missions. Casey also addressed the almost certain cancellation of the Space Launch System (SLS) and the Gateway program, both of which may die after Artemis 3.We also talked about a potential shift toward commercial Moon missions, though Casey noted the plans were vague and lacked clear direction. Our discussion covered broader topics as well, including cislunar development, cargo and resupply missions to the ISS, the outlook for private space stations, Mars exploration, and entry, descent, and landing (EDL) demonstrations.In Part 2 of the program, John focused on robotic missions—both current and planned—which are all heavily reliant on robotic technology. Casey added insights into the impact of budget cuts and restructuring at key NASA centers, including JPL and Goddard. Before concluding, we asked Casey about the implications of these changes for NASA scientists and engineers. He expressed concern about their uncertain job prospects, noting that opportunities for their highly specialized skills may be limited.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: 1-866-687-7223For real time program participation, email Dr. Space at: drspace@thespaceshow.comThe Space Show is a non-profit 501C3 through its parent, One Giant Leap Foundation, Inc.

"The unborn" are a convenient group of people to advocate for. They never make demands of you; they are morally uncomplicated, unlike the incarcerated, addicted, or the chronically poor; they don't resent your condescension or complain that you are not politically correct; unlike widows, they don't ask you to question patriarchy; unlike orphans, they don't need money, education, or childcare; unlike aliens, they don't bring all that racial, cultural, and religious baggage that you dislike; they allow you to feel good about yourself without any work at creating or maintaining relationships; and when they are born, you can forget about them, because they cease to be unborn. It's almost as if, by being born, they have died to you. You can love the unborn and advocate for them without substantially challenging your own wealth, power, or privilege, without re-imagining social structures, apologizing, or making reparations to anyone. They are, in short, the perfect people to love if you want to claim you love Jesus but actually dislike people who breathe. Prisoners? Immigrants? The sick? The poor? Widows? Orphans? All the groups that are specifically mentioned in the Bible? They all get thrown under the bus for the unborn. - Dave Barnhart

God may show no partiality, but we sure are partial to Rev. Dave Barnhart. (oh brudder). Dave talks about his wanton desecration of confederate monuments, the slogans of the early church, and the mysterious appeal of Jethro Tull at our high school. Then Dave gets political with The Great Nations of Europe, and Daniel accidentally discloses his infatuation with Jenna Coleman. 

Dave Barnhart is a writer and Methodist pastor who leads a network of house churches as well as a monthly psychedelic integration meet up in Birmingham, AL. In addition to maintaining a beautifully thought-provoking blog, he is the author of two books, What’s in the Bible About Church? (2008) and God Shows No Partiality (2012). This conversation, recorded the week before COVID-19 and global recession, is as relevant now as ever. Dave shares his experiences participating in a psilocybin study at Johns Hopkins University and his journey to find transparency and vulnerability as a spiritual leader. We talk about guilt culture, the longing and loneliness of life, civic religion and nationalism, disruptive religion (“the kind that Jesus actually preached”), and finding God at the margins. This is good medicine for those striving to navigate these challenging times with integrity, grace, and some kind of sanity. You can find Dave online at SaintJunia.org and  DaveBarnhart.net.

This week Tony and Dr. Dave Barnhart talk about the Straight Pride, denial of racism, and revisionist history. What makes people hold on the specific pieces of a narrative that they know is not true. How can we talk about racism without making white people feel uncomfortable, we can’t.

Can Bonnie and Karen find something funny about the Abortion ban that just passed in Alabama? We’re gonna try! Bonnie found some great articles from satire at The Reductress to Noam Chomsky’s great video of why the Southern states and evangelicals grabbed on to the abortion issue. Cory Doctorow gave a lovely recap that included our new favorite term “musketf*ckers.” Karen and Bonnie both learned about sex in strange ways, from grandmothers to toilet notes.  The Bible never mentions “Do not Abort,” but the religious right picks out verses from the ancient pre-ultrasound era to say God knew you in the womb, sooooooo… Plus, they really love those ten Commandments. But Karen asks “Which Ones??” The ones in Exodus 34:6-7 or in Exodus 34:14-27—the one that includes lots to do with firstborns, donkeys, goats and sacrifices.God “repeated” his commandments to Moses after the first ones broke, but God’s memory seems to be lacking. Bonnie thought the breaking of the tablets was just a Mel Brooks scene from “The History of the World.”  Bonnie discloses a trip to Planned Parenthood. Oh, if Karen had known she even walked into that place when they were Christians, she would have shunned her. Then it’s time to talk about Alabama and their low education standards and high telling-people-what-to-do standard. We highly recommend the podcast S-Town, that isn’t about abortion, but an intelligent guy in Alabama trying to mentally get out. We try and go through the logistics of the Alabama Abortion ban with 14 year olds lined up in prison or financially in debt with fines. Karen talks about a young friend who had an abortion and Karen was conflicted with how relieved she was. We finish with a perfect recounting of the hypocrisy of pro-lifers in a Facebook post by an Alabama minister named Dave Barnhart that should go viral.

This week the guys review Margaret Atwood's, "The Handmaid's Tail", a dystopian society that seemed far fetched in the 80's. In today's political chaos, it seems more plausible than ever. This week we speak with Rev. Dave Barnhart of the St. Junia United Methodist Church to get a religious perspective of the book and where we are as a nation. You can watch the series on Hulu with a new episode on Wednesday nights.
