    Dr. Karen Lloyd discusses her book, "INTRATERRESTRIALS: Discovering The Strangest Life On Earth" Jun 25, 2025
    Show notes

    Please note that there were audio and technical difficulties with this program My apologies.

    Dr. Karen Lloyd, author of INTRATERRESTRIALS: Discovering The Strangest Life On Earth, was our guest for this 63-minute program. We explored a variety of strange life forms that she has studied using deep-sea submersibles such as ALVIN. Although we did touch on some land-based life later in the program, most of our discussion focused on organisms found several hundred to several thousand feet below the ocean surface.

    Early in the conversation, I asked Karen about DNA differences between these deep-sea organisms and surface creatures. She reminded us that her research primarily involves single-celled microbial life, but noted that their DNA is not drastically different from that of more familiar organisms.

    As a former scuba diver in my younger years, I asked several questions about the experience of deep-sea diving in mini-subs: the technology involved, the comfort level (or lack thereof), visibility, and the challenges of discovering and retrieving samples for study. Karen also shared insights about the crew—typically just three people per dive in ALVIN—the duration of these dives, and the training required to participate. One key takeaway was that many samples are collected from seafloor mud, as the life forms are too small to be seen with the naked eye.

    Despite ongoing audio issues during the broadcast, we received several excellent listener questions. One listener asked whether the organisms Karen studies are considered extremophiles—a topic we've discussed before on TSS. Don’t miss her answer—it may surprise you. Another caller inquired about any commercial applications for her research or for the microbial life itself. Karen took time to name some of the organisms currently being studied, so listen closely for those details.

    A listener also raised concerns about ocean pollution and its impact on these life forms. While most of the organisms live too deep to be directly affected, Karen did discuss the broader dangers of plastic and other pollution, stressing that we should take these issues more seriously.

    Later in the program, we tackled a complex question about whether climate change is affecting these deep-sea environments. Karen gave a detailed response that’s worth hearing in full. I also asked if microbial life differs across the world's oceans. While there is some diversity, she explained that the microbes are generally quite similar across different marine environments. She was also asked about microbial life in freshwater lakes, but noted that this is not a primary focus of her research.

    As the discussion continued, I asked Karen about the potential benefits to humans from studying these life forms. Her response was thoughtful and informative—another part of the program you won’t want to miss. Before wrapping up, we discussed how these microorganisms contribute to oxygen production. I mentioned that I thought trees were responsible for that, and Karen explained the significant differences. She emphasized how essential deep-ocean microbial life is to sustaining human life with some good examples.

    Karen dives into all of this and much more in her book, which is an excellent and engaging read. She shares vivid stories that help readers appreciate the science and the importance of this research. While we did experience some audio issues during the show, I encourage you to listen to the entire interview and consider reading her book. This is a truly important subject that deserves our attention.

    Dr. Robert Bishop talks Texas A&M space, science and engineering with us plus the same for the national front. A big Shout Out to Texas A&M! Jun 21, 2025
    Show notes

    We welcomed Dr. Robert Bishop of Texas A&M University to The Space Show for a wide-ranging discussion on space exploration, technology, and education—highlighting Texas A&M’s expanding leadership in space science, engineering, and research.

    After introducing the program and reminding listeners that The Space Show is a nonprofit, listener-supported initiative, I welcomed our guest, Dr. Robert Bishop, Vice Chancellor and Dean of Engineering at Texas A&M. Dr. Bishop began by outlining the university’s major space and science research initiatives. While state-supported, he explained, much of the research is funded through contracts and grants from NASA, the National Science Foundation (NSF), and other agencies. A key development is a new 400,000-square-foot research facility under construction near NASA’s Johnson Space Center, featuring simulated lunar and Martian environments for both academic and industry use.

    Dr. Bishop addressed concerns about potential federal science funding cuts. He expressed confidence in adapting through more efficient funding models, such as forming a 501(c)(3) and expanding contract-based research. He emphasized that contracts should supplement—not replace—traditional grant funding, especially for open-ended basic research. He also called for a reevaluation of indirect cost structures to better sustain future research.

    We explored Texas A&M’s national security-related research, including work in cybersecurity, hypersonics, and space defense. Dr. Bishop underscored the university's partnerships with federal and military organizations and emphasized the need to safeguard critical infrastructure amid rising global competition in space. He expressed concern about the uncertain future of U.S. space dominance.

    Dr. Bishop also introduced the TAMU Spirit platform, developed by Aegis Aerospace, which will host up to 12 experiments every six months aboard the International Space Station (ISS). While acknowledging the ISS’s limited remaining operational timeline, he confirmed that contingency planning is underway for future commercial platforms.

    On space launch, I raised concerns about reliance on SpaceX and recent Starship test failures. Dr. Bishop noted that launch systems fall outside his expertise but acknowledged the importance of diversified infrastructure.

    We discussed Texas A&M’s new space engineering program, which began as a master’s degree in Fall 2023 and will expand to a bachelor’s program in Fall 2024. The program integrates disciplines such as agriculture, architecture, and public policy, with a focus on sustaining human life on the Moon and Mars. While the university is not involved in space medicine or weapons research, it conducts foundational research in hypersonics and maintains active collaborations with astronauts and researchers at JSC.

    Our conversation also touched on the broader Texas space ecosystem, with contributions from UT Austin, Rice, and Baylor. Dr. Bishop emphasized the importance of interdisciplinary research—including studies on the environmental impact of space exploration and the use of small modular nuclear reactors for lunar power. In response to a listener question, he noted that while A&M is not currently working on space-based solar power, they are actively researching nuclear technologies for both Earth and space applications.

    Dr. Bishop spoke to the surging demand for engineering education at Texas A&M, which enrolls over 25,000 engineering students but still cannot meet national workforce needs. On the topic of AI, he described early efforts to create a comparative framework across disciplines, with ethical considerations woven throughout the curriculum—not as standalone courses, but through an integrated, vertical approach. He stressed academia’s responsibility in helping industry navigate the ethical challenges of space exploration.

    In response to one of the many listener questions for this program, we discussed commercial opportunities in cislunar space, including communication, landing, and timing infrastructure. Dr. Bishop described cislunar space as a testbed for Earth-beneficial technologies like space medicine and advanced systems. We also explored concepts such as cycling trajectories between Earth and the Moon, space tourism, and large-scale orbital construction. While he believes current engineering capabilities can support such ambitions, he pointed to the need for more robust launch infrastructure Dr. Bishop highlighted Texas A&M’s contributions to food production research aboard the ISS and noted the ongoing challenges of limited resources and talent shortages. He spoke positively about the university’s close ties with government stakeholders and voiced support for bold space development goals. Before concluding, we briefly touched on student enthusiasm, space settlement, O'Neilian colonies, superstructures, and the emerging potential of space medicine.

    We invite you to share your thoughts and questions for Dr. Bishop on our Space Show blog or Substack page: doctorspace.substack.com.

    The Black Hole Universe Theory with Dr. Enrique Gaztañaga. Should the Big Bang guys start to worry? Jun 21, 2025
    Show notes

    John and I welcomed Dr. Enrique Gaztañaga from the University of Portsmouth in the UK. Dr. Gaztañaga presented an alternative theory of the universe that challenges the established Big Bang model. Since the James Webb Space Telescope (JWST) came online, observations have raised questions about the standard Big Bang theory—questions that Dr. Gaztañaga has been at the forefront of addressing through his new theoretical framework, which is still under active investigation and referred to as the Black Hole Universe Theory.

    As you listen to this two-part program, we encourage you to visit Dr. Gaztañaga's excellent website at

    https://darkcosmos.com

    for more details and a comprehensive list of his published articles. You can also read his latest peer-reviewed work in Physical Review D.

    To briefly summarize from his website: “The Big Bang was not the start of everything, but rather the outcome of a gravitational collapse that formed a very massive black hole — followed by a bounce inside. This idea — which we call the Black Hole Universe — offers a radically different view of cosmic origins, yet it is grounded entirely in known physics and observations.”

    Be sure to check out his papers and learn more about this bold and intriguing theory. We’re certain Dr. Gaztañaga will be a returning guest on Hotel Mars and The Space Show in the future.

    The Black Hole Universe Theory with Dr. Enrique Gaztañaga. Should the Big Bang guys start to worry? Jun 21, 2025
    Show notes

    John and I welcomed Dr. Enrique Gaztañaga from the University of Portsmouth in the UK. Dr. Gaztañaga presented an alternative theory of the universe that challenges the established Big Bang model. Since the James Webb Space Telescope (JWST) came online, observations have raised questions about the standard Big Bang theory—questions that Dr. Gaztañaga has been at the forefront of addressing through his new theoretical framework, which is still under active investigation and referred to as the Black Hole Universe Theory.

    As you listen to this two-part program, we encourage you to visit Dr. Gaztañaga's excellent website at

    https://darkcosmos.com

    for more details and a comprehensive list of his published articles. You can also read his latest peer-reviewed work in Physical Review D.

    To briefly summarize from his website: “The Big Bang was not the start of everything, but rather the outcome of a gravitational collapse that formed a very massive black hole — followed by a bounce inside. This idea — which we call the Black Hole Universe — offers a radically different view of cosmic origins, yet it is grounded entirely in known physics and observations.”

    Be sure to check out his papers and learn more about this bold and intriguing theory. We’re certain Dr. Gaztañaga will be a returning guest on Hotel Mars and The Space Show in the future.

    Bill Gowan talks space advocacy with Congress at the Planetary Society Day of Action. Don't miss it! Jun 15, 2025
    Show notes

    Bill Gowan joined us on this program to share his experience participating in The Planetary Society’s annual Day of Action on Capitol Hill. This year’s event took place in March and included training sessions, group feedback meetings, and visits to numerous congressional offices, primarily engaging with staffers from both the Senate and the House. While the Day of Action had its own structured agenda focused on space advocacy, Bill also brought his personal priorities with him advocating for three key goals: exploring other worlds, defending Earth, and finding life.

    During the first 15–20 minutes of the show, Bill walked us through the process of preparing for and participating in the Day of Action. He discussed the training which was led by Casey Dreier and Jack Kiraly (The Planetary Society’s government relations representative in Washington, D.C.), and what it was like to engage directly with congressional staffers. His detailed narrative offered a strong introduction and background, providing listeners with valuable insights into the experience of citizen lobbying for space.

    Bill took several listener phone calls and responded to numerous email questions, as well as my own. Many of the questions focused on how receptive congressional staffers were to discussions about space, and whether they seemed genuinely interested. A recurring theme was the concern over proposed NASA budget cuts outlined in the President’s so-called “Skinny Budget.” Bill provided helpful context, highlighting how these proposed cuts compared to previous budgets and emphasizing the growing resistance in Congress to such reductions—especially those targeting science programs. One particularly interesting exchange came when I asked Bill if he could tell whether a member of Congress was motivated by genuine interest in space and science—or simply liked spending taxpayer dollars. Bill’s thoughtful response to that question is not to be missed.

    Bill also identified the specific members his group met with. While it's uncertain how any individual member will vote when the full budget bill comes up, Bill reported encouraging signs of support for preserving key NASA programs. Of course, much will depend on the final form of the bill and the political pressure applied during the legislative process.

    Later in the show, Bill made a strong case for civic engagement—encouraging all of us to talk to our elected officials, not just about space but about issues we care about more broadly. His explanation of why this matters was compelling and extended well beyond space advocacy. Before we wrapped up, Bill was asked how he would respond to someone who claims, “The country is broke—we have to cut spending, and that includes space.” His answer to this hypothetical but very real concern was both pragmatic and passionate.

    Finally, Bill was asked if he encountered any “space cadets” among the staffers or members of Congress. He smiled and shared that many expressed enthusiasm for space—citing childhood memories of Apollo, sci-fi movies and TV shows, and a general fascination with the cosmos. He believes many in Congress, even those not on space committees, have a “secret space cadet” gene.

    We thanked Bill for doing a fantastic job of sharing his experience with us and look forward to having him back next March to hear how his next Day of Action unfolds—as an enthusiastic, unpaid, and deeply committed space advocate.

    Hotel Mars with Eric Berger on all things SpaceX & Elon Musk Jun 15, 2025
    Show notes

    John and I welcomed back Eric Berger of Ars Technica to Hotel Mars for a one-segment update and discussion on SpaceX, Elon Musk, and Starship. We began by asking Eric what successful Starship testing would look like for SpaceX. He acknowledged that it's difficult to define clear success metrics at this stage.

    We then discussed the upcoming Demo Test #10, potential hardware and assembly issues, plus Eric elaborated on some of the challenges SpaceX might face. The conversation touched on Starship’s role in NASA's planned Moon missions, the importance of testing in low Earth orbit (LEO), and the need to develop and demonstrate in-orbit refueling capabilities. Eric spoke about the types of fuel Starship uses and highlighted the need to address issues like boil-off during storage in space.

    Before concluding, we asked Eric about the ongoing feud between Elon Musk and President Trump. Eric said it was hard to predict how things would unfold but thought Musk might walk back some of his comments. He emphasized the strategic importance of SpaceX to the U.S. government in both civil space and national security domains. While the FAA could theoretically delay permits in response to Musk’s remarks, Eric didn’t think that was likely at this time.
