The Space Show by Dr. David Livingston

Open Lines, Sept. 8, 2026
The Space Show held an Open Lines discussion on September 8th, with David, John Junt, Joe Pistreto, Marshall Martin, and Dr. Charles Lurio participating. The conversation covered a wide range of topics, starting with a focus on Dr. Eric Weinstein, his criticisms of modern physics and peer review, and his visionary ideas about space and time. The group also talked extensively about SpaceX’s Starship developments, including an upcoming test flight and plans for a new launch site in Louisiana. Other topics included the Artemis program’s timeline and challenges, the political documentary about Elon Musk premiering at the Venice Film Festival, and the ongoing debate about space property rights. The participants also briefly touched on the Roman telescope launch and the concept of black triangle UFOs.
In more detail, our Wisdom Team discussed several topics during their Open Lines show. First up was our conversation regarding Dr. Eric Weinstein, a mathematician and physicist who has been critical of string theory and peer review processes in physics. John explained Weinstein’s views on physics, including his concept of geometric unity and multi-dimensional time, while David expressed concerns about conducting an interview with Weinstein due to his limited mathematical background. Briefly, we mentioned two upcoming programs.
The Space Show Wisdom Team discussed potentially inviting Eric Weinstein to appear on a space show, with David expressing interest in having him as a guest despite concerns about the technical complexity of the discussion. Joe and Marshall shared insights into the challenges of communicating with highly theoretical mathematicians and physicists, noting the significant intellectual gap between experts and the general public. The group agreed that Weinstein’s appearance would likely generate more views and that David would invite him to be a guest on The Space Show.
We went on to talk about the upcoming Starship test flight, which is planned to launch next week, possibly as early as Monday. The payload will include 20 Version 3 Starlink satellites with a total mass of 37 tons, similar to the Apollo Command Service Module and Lunar Module combined. The flight will not attempt to catch either stage at Starbase in Texas, as SpaceX wants to achieve two precision ocean landings first before attempting landing there. Marshall noted that SpaceX currently has a launch window of five days, 21 minutes, 21 hours, and 28 minutes for September 15th, though the date keeps changing frequently.
The group discussed SpaceX’s plans for launch towers, clarifying that the baseline is now 12 launch pads rather than 10, with capacity to potentially launch 30 Starships per day. Joe explained that SpaceX is operating as a Neocloud provider, selling AI compute capacity to companies like Google and Anthropic, while also developing StarMind for satellite data centers in different orbits from Starlink. The conversation also touched on Stoke’s recent billion-dollar funding announcement and a new documentary about Elon Musk debuting at the Venice Film Festival.
The group discussed a new documentary about Elon Musk that is expected to be critical of him, particularly focusing on his political support for Trump and his role in the 2020 election. They agreed that the film would likely generate negative reactions from the left but might not significantly impact public opinion. The conversation then shifted to NASA’s Artemis program, where they discussed challenges with pressure suits for lunar operations, noting that Axiom Space is developing the suits with some capability down scoping to meet deadlines.
The group discussed SpaceX’s timeline for returning to flight, with Charles noting they are still aiming for a launch before the end of the year, potentially with their Blue Moon lunar lander. The conversation then shifted to NASA’s Artemis program, with Joe mentioning that NASA officially targets May or June 2028 for the first crewed moon landing. The discussion concluded with an in-depth conversation about the technical challenges of landing at the moon’s South Pole, including lighting and terrain considerations that affect landing calculations, with Charles explaining the 18.5-year lunar orbit cycle that impacts these calculations.
The group discussed lunar exploration missions, focusing on terrain mapping and lander capabilities. Joseph explained that previous orbiters including Lunar Prospector and Chinese satellites had provided good maps of target areas, while Marshall noted that Blue Origin’s Blue Moon lander still plans to deploy a rover despite NASA canceling its original mission. The conversation then shifted to political pressure regarding President Trump’s goal of putting humans on the moon before his term ends, with Marshall suggesting Trump would follow Elon Musk’s approach of setting ambitious deadlines, though Joe believed safety would prevent rushing an unsafe mission and predicted that Blue Origin’s Blue Moon lander would be more likely to be selected for Artemis IV than SpaceX’s Starship due to its proximity to the Artemis III mission.
The group discussed the limitations of the current ICPS stage on SLS, which lacks sufficient delta-v for lunar missions, leading to discussions about Block 2 and 2A upgrades. The conversation then shifted to space property rights, with David asking Charles about the current status of this topic after 25 years. Charles indicated that while space property rights remain a discussion topic, there hasn’t been a definitive resolution, and he suspects it will evolve based on future space activities and usage patterns. Joe mentioned that the Artemis Accords might have influenced the landscape regarding space property rights.
The group discussed space property rights and jurisdictional challenges in space exploration. Marshall explained that safety zones around spacecrafts and satellites could establish de facto property rights in space, particularly for nuclear reactors on the moon. The discussion included speculation about potential resource discoveries in space, including the Psyche mission to a metal-rich asteroid and the possibility of finding water or valuable minerals. The conversation concluded with updates about the Roman telescope project, which was launched nine months early and under budget, and plans for upcoming shows including one about artificial gravity and space stations with Jules Ross for Sunday, Sept. 13.

The Space Show Presents Scott Edwards of Merit Production are ready! Tuesday, 8-11-26
Quick Summary:
This was a Space Show interview with documentary filmmaker Scott Edwards about his 10-year project following Firefly Aerospace, a rocket company that faced multiple challenges before ultimately succeeding. Scott explained how he first encountered Firefly in 2016 while working on a project for Autodesk, and decided to document the company’s journey after witnessing their early rocket tests and learning about their financial struggles, including losing a promised $30 million investment due to Brexit. The documentary, titled “To the Black,” follows Firefly from their startup days through bankruptcy, restarts, and eventual success with their lunar lander contract and successful rocket launches. The film is set to release on Amazon, Apple, and Google platforms in late September, and during the discussion Scott shared insights about the challenges of both making and selling the documentary, noting that while the content was compelling, the film industry market shifted significantly during production, making distribution more difficult than anticipated.
Detailed Summary:
David introduced the evening’s Space Show program with Scott Edwards, discussing his background as a documentary filmmaker and his work on the Firefly project. David outlined upcoming shows, including guests discussing nuclear weapons in space, microbial life research, and quantum computing with NASA.
Scott explained how he became involved in documenting Firefly’s rocket development after meeting Tom Markusic and other founders while working on a project for Autodesk. He initially filmed rocket tests in Texas on his own time after being encouraged by Eric Solwyn to document the company’s space efforts. When Firefly lost their promised $30 million investment due to Brexit-related issues, Scott realized there was a compelling story to follow, particularly as the company was close to shutting down.
Scott discussed his documentary about Firefly Space Systems in detail, which chronicled the company’s struggles with litigation, funding challenges, and eventual bankruptcy before being rebooted with new investors. He explained that the film follows the company’s journey from closure to restart, highlighting the team’s resilience and passion for their mission. Scott mentioned that the film’s release on Amazon Prime, Apple, and Google Play has been delayed due to legal reasons involving secret rocket technology, with a new release date expected in September.
Scott discussed his documentary about Firefly, explaining how the company expanded from being a small launch provider to developing a lunar lander after winning a government contract. He described the film’s focus on the personal stories and emotional journey of the people involved rather than just the technical aspects of rocket development. When asked about his artistic background as a painter, Scott explained how his visual composition skills influenced the cinematic approach of the documentary, aiming to create beautiful and dramatic imagery that tells a compelling story.
Scott discussed his approach to filming Firefly Aerospace, describing how he viewed the engineers as characters in a story with significant stakes. He explained that the company’s first launch attempt failed when a wire came loose, preventing them from becoming the first to successfully reach space on their initial try. Scott shared that he had unusual access to film the company, with a contract that gave him final cut rights and allowed him to document the process freely, though some leadership was initially concerned about the project’s risks.
Our guest discussed screening his film about Tom Rakusic’s space company Firefly at two sold-out theaters in Austin, where it received positive reception from employees and friends. When asked about future projects, Scott indicated he might collaborate with Tom on filming his new space plane venture at Frontera Space, though he remains uncertain about his direction. The discussion concluded with participants reflecting on whether they would pursue entrepreneurial ventures in the space industry, with Phil expressing doubt about his capabilities and Marshall emphasizing the special qualities required of leaders in such ambitious projects.
Scott did talk about the high-pressure environment for entrepreneurs in Austin’s tech scene, particularly for founders of space companies who risk their reputations when their ventures fail. He explained how Austin’s entrepreneurial ecosystem provides opportunities for his filmmaking business, including working with companies like Aloe Atomics, and described his approach to building his production team “Merit Productions” based on skill and performance rather than traditional employment relationships. When asked about space launches, Scott revealed he hasn’t attended one in person but noted that the documentary’s main subject, Tom, had worked for major space companies including SpaceX, NASA, and Blue Origin before founding Firefly. John asked if Firefly’s name was inspired by the TV series “Firefly,” though Scott couldn’t confirm this but acknowledged it would be an interesting connection.
The group discussed how Firefly Systems has evolved from its early startup days into a larger, more corporate entity with NASA contracts and public IPO status. Scott explained that the company’s culture and approach have changed significantly, moving from a small team working irregular hours driven by Tom’s leadership to a more structured corporate environment. The discussion also covered the documentary film about Firefly’s early days, which premiered at the Atlanta Film Festival under the original title plus the challenges of distributing space-related documentaries through film festivals.
We addressed the challenges in the film industry, particularly how festivals have become disconnected from mainstream audiences by focusing on unique topics rather than commercially viable content. He shared his experience making a documentary about Tom building a rocket in Texas, which initially received positive responses from industry professionals and networks, but faced difficulties when the market shifted during COVID and streaming platforms went bankrupt. The film, which follows an ordinary person rather than a celebrity, struggled to find distribution deals despite initial interest from major producers and networks.
The group discussed a film about a rocket company and its development, with Scott explaining how the story follows a man who brings his space technology idea to life despite facing obstacles. David praised the film as unique among space stories, noting how few great space ideas are actually implemented. When asked by Phil about omitted content, Scott explained that he left out the lunar lander project and various rocket tests in Texas due to space constraints in the film, as the story needed to focus on the main rocket development rather than side projects.
Scott discussed the challenges of filming a rocket company, including the pressure to capture significant moments and the difficulty of balancing content length with storytelling needs. He explained that many beautiful test scenes were cut from the film to focus on the most important parts of the story, though some startup culture and investor pitch scenes were included. The group briefly discussed the potential for creating additional content like time-lapse footage or a “geek version” of the film, but concluded that a niche market might not support such a specialized product.
The documentary, “To the Black” about Firefly Aerospace, which will be released on Amazon, Apple, and Google platforms in late September. He described interviewing local residents in Briggs, Texas who surround the rocket test site, capturing their mixed reactions to the space company and the cultural clash between the educated rocket scientists and local farmers.

The Space Show Presents Dr. Alan Stern, Friday, Aug. 28, 2026
Quick Summary
The Space Show featured Dr. Alan Stern discussing the New Horizons mission, its recent 11-month hibernation, and ongoing scientific activities in the outer solar system. Stern explained the mission’s budget constraints, which limit ground operations and data return, and the need for additional funding to keep heliospheric instruments running. He detailed the spacecraft’s current position, its study of the Kuiper Belt, and the search for a new flyby target using ground telescopes and the upcoming Roman Space Telescope. Stern shared new findings about Pluto, including evidence of liquid nitrogen flows, and highlighted the diversity of trans-Neptunian objects. The conversation also covered future propulsion technologies like nuclear thermal and fusion, their potential to revolutionize space travel, and the concept of a mission to intercept interstellar comets. Stern answered questions about spacecraft operations, instrument capabilities, and the challenges of deep space communication.
Detailed Summary
The Space Show welcomed listeners and introduced Dr. Alan Stern, the principal investigator of New Horizons, as the guest for the Friday Space Show. Alan explained that New Horizons hibernated for 11 months from August 2025 to June 2026, during which some subsystems were turned off while others, including three scientific instruments, recorded data continuously. He noted that hibernation was primarily due to budget constraints, as sufficient funding was not available to staff mission control year-round or operate all scientific instruments.
Our guest explained that New Horizons has three scientific instruments: a dust detector studying Kuiper Belt dust distribution, and two plasma spectrometers measuring the Sun’s outer heliosphere. The spacecraft can perform targeted flybys like the 2019 encounter with Arrokoth, with plans to search for another flyby target using ground-based telescopes and potentially the Nancy Grace Roman Space Telescope. Alan clarified that the mission’s operational lifespan is limited by the spacecraft’s nuclear power supply, which will lose power around 2050, rather than communication range issues, making it impossible to continue operations beyond that time.
Alan provided updates on New Horizons’ current position at 66 astronomical units from the sun and discussed the mission’s trajectory toward the galactic center direction, similar to the Voyagers but in the plane of the solar system. He explained that New Horizons will likely leave the Kuiper Belt within the next 7 years, depending on its extent, and shared recent discoveries about Pluto’s Sputnik Planitia glacier showing evidence of liquid nitrogen flow. Alan highlighted budget constraints affecting the mission, noting they need additional funding to staff mission control and keep heliospheric instruments operational, as data transmission requires significant human oversight to manage the spacecraft and deep space network coordination.
Discussed in detail, the New Horizons mission and its capabilities, highlighting that the Roman telescope would be crucial for their current search as it offers 50 times the capability of James Webb for this type of exploration. When asked about the impact of AI on spacecraft design, Alan explained that while AI could help speed up processes and reduce risks today, it was not available during New Horizons’ design in the early 2000s, though the spacecraft remains fully functional after nearly 21 years. Alan also provided details about the Arrokoth flyby, explaining they passed at a distance of a few thousand miles and that Arrokoth measures about 35 kilometers in length, and confirmed that New Horizons continues to collaborate with Johns Hopkins Applied Physics Lab for mission control and spacecraft operations.
Alan discussed the surprising diversity of Kuiper Belt objects, explaining that these dwarf planets exhibit greater diversity in parameters like composition, satellites, and reflectivity than the terrestrial planets. He recommended a mission to Triton as it would provide insights into Pluto while also allowing study of the Neptune system with better instrumentation than Voyager. When asked about the chemical composition, Alan described three main categories: objects with super-volatile ice like molecular nitrogen and carbon monoxide, those with organic molecules, and water ice balls similar to giant planet satellites. Alan also shared his experience flying on Virgin Galactic’s spacecraft in 2023 and discussed how Starship would be a gamechanger for future planetary missions, particularly enabling human colonization of Mars and other missions that weren’t possible before.
The importance of nuclear propulsion systems for space exploration was talked about, explaining that while chemical rockets are necessary for Earth launch, nuclear fission and fusion systems could significantly reduce transit times across the solar system. He highlighted that nuclear systems offer specific impulses 10-100 times higher than chemical rockets, with fusion drives potentially enabling travel to Pluto in under a year. The group discussed specific technical details about nuclear thermal propulsion, with Alan recommending that interested parties consult NASA’s development plans and the Helicity Space website for more information. At the end of the discussion, Alan offered to provide contact information for Stephane Lintner, CEO of Helicity Space, for potential media opportunities.
Bill proposed an idea for the end-of-life operation of the Voyager spacecraft, suggesting that when it can no longer point at Earth, it could be put into a tumble to transmit an intermittent carrier wave signal. Alan explained that while the concept was interesting, the Voyager high-gain antenna’s narrow beam would likely make successful Earth communication intermittent once it loses tracking ability. Alan also discussed his work on fusion propulsion systems for spacecraft and mentioned plans for a potential NASA mission to intercept interstellar comets, which would require rapid response capabilities. The group discussed the temporary naming of Ultima Thule and its eventual formal naming process.

She explained how she was initially tasked with working on the Artemis I program, ISS experiments, and Antarctic balloon experiments. When asked about the types of microbes used in space research, Tiffany clarified that “microbes” was a blanket term for microorganisms like yeast, fungi, and bacteria, and explained that the choice of organism depends on the research question and factors like feasibility, safety, and hardware compatibility with space environments.
Tiffany explained a space mission where her team sent Aspergillus niger spores to the moon on Artemis I, packed in gelatin capsules with phase-changing media to allow germination during the two-week journey. The experiment was designed to be passive, with the fungi growing in microgravity while experiencing gamma radiation, though no cameras were included to capture the process in real time. David asked about the medical implications of Aspergillus niger, to which Tiffany confirmed it can cause health issues for immunocompromised individuals, though it is generally tolerable for healthy people.
Tiffany discussed the potential for finding fungi on other planets, noting their 50% genomic homology with humans and their resilience to extreme conditions, including high temperatures and radiation. She explained how microgravity affects fluid behavior and nutrient transport in cells, leading to altered growth rates and phenotypes. When asked by John Jossy about the potential benefits of artificial gravity, Tiffany suggested it could help mitigate these issues but also highlighted how microgravity forces organisms to adapt and produce specialized compounds.
Marshall discussed the potential use of amino acid chirality as a methodology to determine whether organisms are space-sourced or Earth-sourced, noting how radiation exposure could cause mutations in amino acids. Tiffany explained that while the International Space Station (ISS) is shielded from most radiation, UV radiation could potentially introduce mutations in organisms like fungi and algae. When asked about conducting research in space labs, Tiffany expressed interest in the potential benefits, particularly for fresh sample processing, though she noted personal challenges with space travel due to motion sickness.
Tiffany discussed the challenges of space biology research, explaining that while Aspergillus niger is a reliable organism for their experiments, she hadn’t considered exploring other organisms due to comfort with the current setup. She described their work on engineering microbes to produce specialized chemicals and biomaterials for potential biomanufacturing in space, which could strengthen domestic supply chains. Tiffany noted that space biology research faces significant competition for funding, making it challenging to secure resources for these types of projects.
Our guest discussed her work in space biology, explaining that while her research doesn’t currently focus on human biology during pregnancy or space settlement, she is interested in producing novel chemicals and compounds that could potentially be used for medicine. She described her day-to-day activities as primarily involving engineering yeast to produce chemicals of interest and conducting strain characterization, with some omics-based research being handled by others. When asked about responding to criticisms of space spending, Tiffany indicated she hasn’t encountered negative views but would emphasize the unique opportunity to work with astronauts and send samples to space. She also explained that her research only involves non-toxic BSL Level 1 organisms due to safety constraints.
David and Tiffany discussed the purpose of studying organisms in space to understand their responses and potential adaptations that could benefit human health in Earth’s environment. Tiffany explained that certain compounds produced in microgravity could lead to beneficial mutations and adaptations that could protect astronauts and future warfighters. When asked about launch costs, Tiffany indicated she was not privy to specific cost details, though she acknowledged that space missions are expensive and costs vary based on payload size and complexity. Tiffany also shared her experience attending launches at Kennedy Space Center, including the Artemis and Starlink missions, though she noted that schedule delays required multiple visits.
Tiffany further explained that simplicity is crucial when designing space experiments due to hardware limitations and astronauts’ tight schedules. She noted that while simple experiments can be successful, complexity constraints limit what can be accomplished in current space labs. Tiffany expressed optimism that robotic labs in future commercial stations could enable more complex experiments, allowing researchers to monitor and control them remotely.
In summary, Dr. Hennessa discussed her work on microbial research in space, including the use of robotic systems to handle samples and the importance of considering sample size and space limitations. She expressed interest in testing samples at different gravity levels and explained her team’s role in the project. The discussion also touched on concerns about potential mutations in space and the feasibility of bringing samples back to Earth. David and the team discussed upcoming Space Show programs and topics, including a show on quantum computing and internet stability. The conversation ended with a brief conversation about Manuel’s research on osteoarthritis in microgravity.
