The Space Show Present Manuel Cuba with The Space Show Team for a general discussion, Sunday, 6-14-26
Meeting Summary:
The meeting was a space show discussion hosted by David Livingston, with participants including Manuel, Philip, GuySchumann, Marshall, John Jossy, and Sherry. The main guest Cesar from Peru was expected to join but experienced technical difficulties connecting from the airport, so the group decided to reschedule his full interview. The participants discussed various space-related topics including SpaceX’s recent IPO, the government’s UAP document release, ISDC conference experiences, and NASA’s Artemis III crew selection. GuySchumann provided updates on his work in drought mitigation using space-based predictive analytics, while the group also shared insights about recent space conferences and debated whether crew weight and mass considerations might factor into lunar mission planning.
Detailed Summary
Manuel shared his positive experience attending AIAA in Washington D.C., describing it as worth every penny despite the high cost. The group discussed the potential duration of an upcoming show, with Manuel indicating it should be between 60 and 90 minutes and mentioning that Caesar would have significant content to share. The conversation briefly touched on SpaceX’s recent IPO and the mixed opinions from the financial community regarding its economic prospects and future quarterly reporting requirements.
The group discussed David’s having seen the Spielberg movie, “Disclosure Day,” which explores the concept of “Disclosure Day” regarding extraterrestrials. David reviewed the movie positively, noting it features good acting and innovative storytelling, though he personally doesn’t share Spielberg’s precise views on extraterrestrials nor how disclosure day will take place, assuming it ever does take place. .
Guy Schumann discussed a follow-up conversation with Chris Bures from his last program appearance with us when a listener from Las Vegas, Chris, engaged him and his company about water supply and drought issues in Nevada and the west, where Chris had offered to connect him with municipal and state contacts but the response status remained unclear. Guy explained that while they don’t currently have direct municipal contacts in Las Vegas, they partner with a Florida-based company to provide flood modeling and risk assessments for counties in the US, though this partnership is currently focused on Florida rather than the Western states. Marshall raised concerns about weather pattern challenges in Oklahoma, specifically the need to manage both drought and sudden heavy rainfall during harvest season, which Guy acknowledged as a widespread issue affecting both European and US agriculture.
The group discussed challenges in predicting and preparing for extreme weather events, with GuySchumann highlighting the difficulty of predicting short-acting events and staying within community budgets. Marshall shared that his brother-in-law could significantly increase crop output with just four months of weather prediction, leading to a discussion about seasonal forecasting improvements enabled by AI and space data. GuySchumann described the rapid technological development in extreme weather prediction over the past five years, noting that progress has accelerated to the point where conferences are overwhelming due to the pace of innovation.
The Wisdom Team discussed SpaceX’s recent IPO, with Philip noting that many retail investors are making long-term bets on space exploration rather than seeking immediate returns. Marshall expressed caution about buying shares until next week, while David mentioned plans to purchase shares for his trust to benefit his children. Manuel recommended reading Robert Zimmerman’s blog post about the IPO, though David thought Zimmerman was overly optimistic. John Jossy observed that space stocks were down on Friday, with some speculation that investors were selling other space companies to buy SpaceX shares.
We talked at length about SpaceX’s IPO and Elon Musk’s public approach to his companies. GuySchumann shared his perspective on Musk’s vision for space exploration and how it could inspire public investment, comparing it to the excitement around early personal computers. The discussion touched on how Musk’s public persona and rhetoric might change due to SEC oversight, with GuySchumann suggesting he would be more careful out of a sense of responsibility to shareholders. The conversation also covered the regulatory challenges Musk would face as a public company CEO and the potential for litigation, while Marshall noted that Shotwell appears to be the next person in line for leadership at SpaceX.
Phil reported that his presentation about moon-based data centers went well at ISDC, with good audience engagement and questions. He also mentioned other notable speakers including David Dillon from Electromagnetic Launch who discussed quench gun technology, and presentations about Venus colonization and biological methods for making structural components in space. David expressed frustration about Blue Origin’s reluctance to participate in his show, noting that the company prefers controlled environments where they can restrict discussion topics rather than facing an unpredictable audience.
The group discussed keynotes from a recent space conference, including presentations by Harrison Schmidt, Lindy Tompkins, and Bill Diamond of SETI. Manuel shared insights from his attendance at the conference, where he met with Space Tango and a South Korean pharmaceutical company to explore low Earth orbit life sciences facilities and potential research opportunities with the Department of War. The participants also briefly discussed the recent U.S. government’s UAP document release, noting that while it generated some media attention, it didn’t receive widespread public focus.
The group discussed the upcoming Spacecom conference in January in Florida, which Manuel found interesting due to its focus on satellite communication and launch systems. They also discussed the timing of the next SpaceX Starship test flight, which is targeted for July 2026, with speculation about whether it might coincide with the July 4th holiday. The conversation then shifted to discussing Keith Cowling, who received a Pioneer Award from NSS despite controversy, and the upcoming NSS elections where several space show personalities are running for positions.
The team mentioned NASA’s selection of an all-male crew for the Artemis III mission, with Phil proposing a theory that the heavier male astronauts were chosen for this low-orbit mission to maximize payload capacity, while future missions might favor lighter crew members including women. The discussion included technical considerations about weight, oxygen consumption, and space requirements for astronauts, with David sharing insights from his scuba diving experience about how weight and gender can affect mission planning. The conversation ended with plans to reschedule Cesar’s interview.

The Space Show Presents Rick Fisher, Tuesday, June 9, 2026
Quick Summary
The Space Show featured a discussion with national security consultant Rick Fisher about China’s space program and its implications for national security. Rick explained that space has become a major component of American global national security considerations, with China positioning itself either as a major antagonist or cooperative partner depending on Earth-based conflicts. He detailed China’s lunar program, including their Lanyue lunar lander and their manned capsule, while warning that Chinese dual-use systems on the moon could potentially extend Earth conflicts to lunar territory. The conversation covered China’s energy independence efforts through nuclear fission, space solar power, and fusion energy development, as well as their reusable rocket capabilities with 20-25 Chinese companies developing reusable launch vehicles similar to SpaceX’s approach. Rick also discussed the Artemis program’s goals of establishing a semi-permanent presence on the moon by 2036, requiring 79-81 space launches and approximately $30 billion in total investment. The discussion concluded with analysis of Taiwan’s potential response to Chinese aggression and the role of other Asian countries like India and Japan in balancing Chinese space ambitions.
Detailed Summary
David and Rick discussed the role of space in national security, particularly regarding China’s lunar program and its implications for Taiwan and the South China Sea. They also touched on UAPs (Unidentified Anomalous Phenomena), with John contributing insights about China’s interest in UAPs and the government’s handling of the topic. The conversation highlighted differing perspectives on the significance of UAPs and the potential motivations behind government secrecy regarding the subject.
David, Rick, and John discussed concerns about Chinese influence and espionage in the United States, including allegations against politicians like Feinstein and a California politician. They questioned why such activities are tolerated despite being known. The conversation then shifted to SpaceX’s upcoming IPO and its performance. The conversation continued with the guest continuing to discuss China’s space program and its broader implications for national security.
Rick discussed the increasing importance of space in American national security, particularly in relation to China’s space activities. He explained that space has become a determinant factor in global security, with both countries positioning themselves as either antagonists or cooperative partners. He praised President Trump’s focus on returning to the moon through the Artemis program as a way to deter conflict and secure American access to space. He noted that Trump’s second-term goal of establishing a permanent presence on the moon could help prevent conflicts not only on the moon but also in low Earth orbit and potentially on Earth.
Rick was asked about China’s energy strategies and vulnerabilities, explaining that China’s reliance on oil passing through the Straits of Hormuz presents a strategic weakness. He detailed China’s multi-pronged energy approach including nuclear fission plants, space solar power research, and fusion energy development. When asked about space-based data centers, he indicated China is following the American trend with plans to launch such facilities in the near future, potentially on a large scale to support AI functions on Earth. The discussion was cut off before John’s question about potential lunar conflict could be addressed.
Our guest discussed the potential risks and challenges associated with China’s lunar lander program, particularly regarding the Lanyue lunar lander and its propulsion stage, which could pose hazards to other lunar missions or bases. He highlighted the need for deconfliction and transparency from China regarding their lunar lander operations. Rick also mentioned the deployment of hopper drones by both the United States and China around the moon, noting the potential for these to be modified for combat purposes if tensions escalate on Earth.
China’s potential space ambitions were brought to our attention, noting that if China were willing to use technology for political intimidation in low Earth orbit, they might extend similar activities to lunar or Martian environments. John suggested that getting to space first could provide an advantage in staking territorial claims. Dr. Kothari asked three questions about China’s plans: circumnavigating the moon with astronauts in 2027, deploying thorium molten salt reactors for terrestrial use, and developing reusable rockets. Rick acknowledged limited knowledge about China’s reactor plans but noted that China has 20-25 companies working on reusable space vehicles, with the potential for first stage recovery this year.
Rick discussed China’s space launch vehicle developments, focusing on the Long March 12, Long March 10, and the proposed Long March 9. He explained that Long March 10 could become a popular reusable launch vehicle, while the three-stage Long March 9, if developed, would be the world’s most powerful space launch vehicle with a massive 19-meter payload fairing. Rick speculated that China might be developing the three-stage Long March 9 to avoid the complexity of low Earth orbit refueling required for Elon Musk’s Starship, though he acknowledged that many technical details about its feasibility remain unknown.
Rick discussed the potential impact of China’s Long March 9 rocket on SpaceX’s Starship, noting that while the first stage would be reusable, it remained unclear whether China would pursue reusability for the second stage. When asked about credible resistance movements in China, Richard explained that while there is a will among some people to resist the government, the Chinese Communist Party effectively prevents such movements through extensive digital surveillance and control systems. He compared China’s digital surveillance capabilities to Iran’s and highlighted how Israel’s ability to take control of Iran’s digital systems and use them against the regime should serve as a warning to China about potential threats from Taiwan and Israel.
Ajay asked Rick about Taiwanese opinions on potential reunification with China. Rick explained that while many Taiwanese benefit economically from China relations, over 90% of the population values their democratic freedoms and would not willing give them up to become part of a Chinese communist dictatorship. He noted that the Chinese Communist Party’s failure to acknowledge historical atrocities under Mao, including the deaths of 50-70 million people, undermines their historical appeals to Taiwanese people.
Rick talked about the potential for Asian and oceanic countries like India and Australia to balance China’s space activities through collaboration with the United States and the Artemis program. He noted that as these countries develop their own heavy launch vehicles, they will gain more autonomy to pursue lunar and Mars programs independently of potential Chinese-American conflicts. Richard also praised NASA’s Artemis program revealed on March 23, which aims to establish a semi-permanent presence on the moon by 2036 through 79-81 space launches and $30 billion total investment, describing it as essential for winning the race to the moon and potentially deterring Chinese aggression.
Our guest also discussed the relationship between China’s space program and the US, noting that while competition exists, cooperation could follow a similar path to Cold War-era US-Soviet relations. He expressed confidence that the Artemis program would continue regardless of political party in power, though funding levels might vary. Richard believed the program would maintain strategic importance in the Earth-Moon-Mars system and would only be disrupted by major global conflicts.
The conversation ended with David thanking Rick for his participation and discussing upcoming shows featuring Chris Carberry from Explore Mars and guests from Peruvian satellite systems and Luxembourg.

Dr. Eligar Sadeh, Tuesday, May 5, 2026, #4535
Quick summary
The Space Show featured a discussion with Eligar Sadeh, editor of the Journal of Astropolitics, about the recent Space Symposium in Colorado Springs and cislunar space governance. Sadeh explained how the symposium focused heavily on establishing U.S. dominance in cislunar space, particularly through the Artemis program, with emphasis on being the first mover in establishing governance structures and rules of engagement. The discussion covered concerns about NASA science budget cuts, the sustainability of the Space Launch System, and the role of public-private partnerships in lunar development. Sadeh noted that while the U.S. space community emphasized military and strategic priorities, international scholars, particularly from developing space nations, were increasingly contributing to astropolitical research through his journal. The conversation also touched on challenges with Starlink satellite congestion and the potential for space asset disruption, though Sadeh emphasized the importance of establishing international governance frameworks to prevent harmful interference in space.
Detailed Summary
Eligar discussed his recent activities, including his work as an adjunct professor at the University of Colorado, his involvement with the journal Astropolitics, and his focus on lunar governance and astropolitics. He highlighted the growing interest in cislunar space and lunar governance, noting a significant increase in paper submissions to the journal and plans for a special issue and international conference on the topic. Eligar also mentioned the prominent role of defense and military interests in the current space industry, particularly with the Space Force’s increasing budget and focus on space superiority. The conversation touched on personal updates, including Eligar’s children’s current activities and his relationship status.
Eligar discussed the emerging focus on cislunar space at a recent space symposium, highlighting the strategic importance of establishing governance structures and securing gravitational high ground in the Earth-Moon system. He noted that while the Artemis program aims for aggressive lunar exploration and potential human habitation by 2032, there are significant challenges with the Space Launch System’s sustainability and the reliance on new commercial capabilities like SpaceX’s Starship. Eligar emphasized that the civil program appears to be a cover for establishing U.S. superiority in the cislunar domain, particularly in response to geopolitical competition with China and Russia.
The discussion focused on concerns about proposed NASA science cuts and their impact on the space community. Eligar noted that while there was awareness of these cuts during networking discussions at the Space Symposium, there was limited pushback, with many participants appearing to align with the Trump administration’s direction. The conversation then shifted to broader governance challenges in the cislunar domain, with Eligar emphasizing the need for maintaining space as a commons and establishing rules for interoperability among the 62 states participating in the Artemis program. The discussion concluded with a reference to a 20-year-old paper co-authored by Eligar and David on public-private partnerships in lunar development, which remains relevant to current space governance challenges.
Eligar discussed the challenges of establishing a permanent lunar presence, highlighting issues such as freedom of movement, resource utilization, and the harsh lunar environment, including metallic and adhesive dust. He emphasized the need for reusable and sustainable lunar transportation systems, suggesting that achieving a cost of $100 per kilogram with Starship could be crucial. Eligar also explained the concept of cislunar space as the gravitational high ground incorporating Lagrange points between Earth and the Moon, which provides access to various orbital domains and the lunar surface. Joe noted the disconnect between desired goals and current capabilities, advocating for increased repetition in accessing lunar space to support a permanent presence.
The discussion focused on NASA’s lunar mission plans and budget constraints. Joe expressed concerns that the Moon Enterprise would likely crowd out other NASA programs due to limited congressional funding, similar to previous large initiatives like the Space Shuttle and International Space Station. Eligar agreed that SLS is not sustainable, noting it’s only planned for up to Artemis 5 with a cadence of one launch per year, and emphasized the geopolitical aspects driving the lunar race, including the need for reusable transportation systems and establishing a presence in the Aitken Basin for potential mining opportunities.
The discussion focused on the Space Symposium’s emphasis on getting to the lunar surface first rather than focusing on sustainability or cost efficiency. Eligar noted that while there was general support for the Artemis program and Accords, there was limited discussion about alternative lunar surface models or modifications to the current Artemis plan. The conversation highlighted a potential disconnect between the symposium’s rhetoric about achieving rapid progress and budgetary realities, including concerns about over-reliance on Starship variants and cuts to science programs. John suggested that the science program cuts might be a strategic budget maneuver similar to defense programs, with the expectation that Congress would eventually restore funding.
Eligar discussed NASA’s proposed permanent lunar presence around 2030 and debated various technical choices in rocket design and propulsion. The conversation then shifted to concerns about space congestion, particularly with multiple satellite constellations being planned by different countries, though Eligar noted that cislunar space remains decades away from similar congestion issues. David raised questions about the global scope of the astropolitics journal, with contributions coming from scholars in developing space states who are focused on using space for socio-economic development rather than military dominance.
The group discussed perceptions of Jared Isaacman and NASA’s leadership in space governance, particularly regarding the Artemis program. Eligar explained that while there are good ideas in the current approach, there are concerns about U.S. dominance in space policy, noting a European concept of “equivalence” where different countries could develop governance approaches independently while maintaining interoperability standards. The discussion highlighted the tension between U.S. efforts to establish space superiority and the need for international cooperation, with Joe emphasizing that China and the U.S. are the dominant powers in space, making other countries effectively choose between aligning with one of these powers.
We also discussed the growing importance of satellite communication systems for military purposes, with Joe noting that multiple countries are developing Starlink-like systems following the Ukraine war. They explored the challenges of denying access to these systems and the potential for kinetic attacks on satellites, with Eligar emphasizing the importance of establishing governance structures and rules of the road in space. The discussion concluded with Eligar providing an update on the journal Astropolitics, which is growing in influence among emerging space powers and has expanded its editorial board with new members including someone from the Romanian Space Agency.
Eligar then mentioned plans for a special issue of Astropolitics journal focused on lunar astropolitics, governance strategy, and policy dynamics in cislunar space, with a global conference planned for early next year and publication expected in a year to year and a half. He agreed to provide David with contact information for potential guests for the Space Show and discussed the possibility of updating a previous article with Haym and himself in the fall. Regarding the timeline for returning humans to the Moon, Eligar expressed doubt about the 2028 target, suggesting 2030 would be more realistic due to ongoing challenges with the lunar landing vehicle.
The group discussed public-private partnerships in space, with Eligar noting that realistic timelines for landing vehicles are now around 2030 rather than 2028 due to delays on both Blue Origin and SpaceX sides. Joe raised questions about international public-private partnerships, particularly in countries like India, while Eligar shared insights about emerging space capabilities in countries like Brazil, Cambodia, Thailand, and Indonesia. The discussion concluded with plans to follow up on these topics in a future issue of Astropolitics journal, with Eligar offering to rewrite and get the paper peer-reviewed.

The Space Show Presents Open Lines Discussion Today, Sunday, 5-3-26
Quick Summary:
This meeting focused on open discussion topics in space exploration and national security. Bob shared speculation about a potential SpaceX acquisition of 200+ square miles of land in Louisiana for data centers and manufacturing facilities, though this remained unconfirmed. The group extensively discussed the Artemis 3 mission delay, with participants debating the challenges of SLS rocket assembly versus SpaceX’s Starship development approach. Ajay raised significant concerns about Russia’s nuclear-powered missile program, specifically the Burevestnik missile tested in October 2025, which he described as difficult to detect and potentially dangerous. The conversation also touched on nuclear power applications for data centers and military bases, with Dr. Ajay mentioning new small modular reactor companies emerging in the market. The discussion concluded with debate about defense strategies against such nuclear capabilities and the current state of hypersonic weapons development.
Detailed Summary:
Bob discussed a speculative story about SpaceX potentially acquiring a 200-square-mile piece of land in Louisiana, which could be used for data centers, satellite manufacturing, and Starship production. He noted that this would allow SpaceX to shift operations away from California. The conversation concluded with a mention of Artemis 3’s delay and a brief reference to Robert’s recent article about the potential Louisiana land acquisition.
David announced that Robert would be scheduled for a show on May 26th at 6 PM, and discussed upcoming shows including Dr. Eligar Sadeh returning on Tuesday to discuss Astropolitics journal reviewing opportunities. The group briefly discussed unconfirmed news about Elon Musk’s salary and potential Mars colonization plans, though Bob repeated that much of this information was speculative. David also mentioned upcoming shows including an ISDC episode with Rod Pyle and Aggi Kobrin on May 12th.
Bob shared unconfirmed rumors that SpaceX may be acquiring approximately 136,000 acres of coastal Louisiana marshland near Pecan Island for potential data centers and manufacturing facilities. The discussion explored the strategic benefits of this location, including proximity to intercoastal waterways, power infrastructure, and natural gas facilities, though participants noted concerns about launch debris dispersion and local community impact. The group acknowledged this was speculative information pending official confirmation from SpaceX.
The group discussed the delay of the Artemis III mission, with Bob explaining that both Blue Origin and SpaceX requested additional time to prepare their landers for an Earth-orbiting test mission. Robert noted that this delay would impact the scheduling of subsequent Artemis missions in 2028, as SLS rockets can only be assembled one at a time using a single mobile launcher. The discussion compared SLS and Starship assembly processes, with Joe highlighting how SLS involves numerous complex steps due to its design requirements, while Starship’s assembly is more streamlined. Bob concluded that Jared Isaacman’s goal is to demonstrate SLS’s limitations over the next two years, potentially paving the way for Starship and New Glenn rockets to replace SLS in the future.
The group discussed the competitive dynamics between SLS and Starship programs, with different perspectives on NASA’s intentions. Phil and Joe had a different view, suggesting NASA believed SLS could beat Starship if it increased production rates faster. The discussion also covered technical aspects of Starship’s design, with Ajay raising concerns about the high dry weight requiring multiple refueling trips to the moon, while Marshall and others highlighted the importance of SpaceX’s new launch facilities in enabling frequent launches.
The group discussed different approaches to refueling a lunar mission depot, with Ajay presenting a plan involving expendable tankers while Phil and Bob described a reusable tanker concept aligned with SpaceX’s philosophy. Ajay cited NASA and Aerospace Corporation analyses suggesting 10-16 refueling launches would be needed with expendable tankers, though the group noted these estimates were based on V2 configurations rather than the more efficient V3. Bob defended SpaceX’s approach, emphasizing the company’s focus on reusability and rapid launch capabilities, while acknowledging that current payload limitations might require temporary use of expendable vehicles if development timelines don’t meet requirements by mid-2027.
The group discussed SpaceX’s Starship program and its potential, with Ajay cautioning against extrapolating success from Falcon 9 to other projects. David interrupted the Starship-focused discussion to broaden the conversation, particularly wanting Ajay to share insights about a new Russian nuclear-powered missile system that can fly at low altitudes and evade detection. Ajay explained that this missile system, demonstrated on October 21, poses a significant threat as it cannot be detected by current defense systems and could potentially remain airborne for extended periods. When asked about countermeasures, Ajay indicated he had provided suggestions to defense departments but could not share details in the open forum.
Ajay discussed his work on hypersonic and nuclear power applications, highlighting his experience since 1990 and recent developments in nuclear power plants. He mentioned new companies like ILO Atomics and Astra working on 10-megawatt power plants for data centers, which could be factory-built within a year. Ajay also shared his conversations with senators about the Burevestnik missile and his meeting with Jared at Mar-a-Lago, where he inquired about the Falcon Heavy idea. Marshall raised concerns about the time required for permits for nuclear power plants, to which Ajay responded that recent executive orders have reduced the timeline to 3-6 months.
The discussion focused on nuclear power applications, particularly small modular reactors and micro-reactors. Ajay explained his work on a 25-megawatt thermal power plant design and discussed the military’s micro-reactor program, noting that molten salt reactors would be more suitable than pressurized water reactors for energy applications. The conversation also addressed hypersonic missile technology, with Ajay clarifying that current U.S. hypersonic programs use rocket-boosted systems with limited range, distinguishable from the nuclear-powered hypersonic missiles discussed in the context of Russian weapons. John Hunt suggested that developing such nuclear-powered systems might not be a priority for the U.S. given existing deterrent capabilities and potential public opposition.
The group discussed Russia’s nuclear-powered missile development, specifically the Burevestnik missile tested on October 21, 2025, which flew for 15 hours at subsonic speeds and demonstrated capabilities to evade missile defenses. Ajay emphasized the danger of these nuclear-capable missiles, noting their ability to approach from any direction and their challenging detection due to flying at low altitudes. cautioned that Russia’s technical competence with high-tech projects should be viewed with skepticism, though acknowledged the need to address these developments. The discussion concluded with Dr. Ajay expressing skepticism about fusion energy timelines and advocating for Generation 4 nuclear reactors, particularly molten salt reactors using thorium or uranium-233.
The group discussed thorium reactors and fusion technology. Ajay explained that China copied thorium reactor technology from Oak Ridge National Lab in the 1960s, but development was halted due to lack of plutonium production, despite its potential for clean energy. The discussion covered fusion for space applications, with Ajay expressing skepticism about the feasibility of Pulsar Fusion’s proposed system due to the high energy requirements and weight constraints for space travel. The conversation also touched on the challenges of space-based data centers, with participants questioning the practicality of using space for cooling purposes given existing technical limitations.
The group discussed space-based data centers and energy transmission methods. Joe explained that Overview Energy, backed by Meta, is exploring using infrared lasers to transmit energy from space to ground-based solar farms. Bob highlighted that while space data centers may not be economically viable, they could drive significant launch demand and benefit the aerospace industry. The discussion also touched on the massive capital expenditure plans of major tech companies, with Joe noting that approximately $750 billion in capital expenses could potentially include space-based data center projects, creating new opportunities for rocket companies.
The group discussed the challenges of cooling data centers in space, with Ajay explaining that radiating heat into space requires large radiators due to the lack of convection and conduction in vacuum. Joe noted that operating chips at higher temperatures could reduce the size of radiators, but this would negatively impact performance. The discussion also covered nuclear propulsion options for space travel, with Ajay expressing skepticism about the feasibility of implementing nuclear electric propulsion for the planned Mars mission within the proposed timeline. The group agreed that nuclear thermal propulsion, while more efficient, would require significant development time and testing. (Summary provided by Zoom AI).

The Space Show Presents Shubber Ali, Sunday, 4-19-26
Quick Summary:
This Space Show program featured Shubber Ali, the original founder of Space Cynics, discussing his return to critiquing space industry claims and over hyping. Shubber explained how Space Cynics began in the mid-2000s as a blog focused on questioning exaggerated claims about space technology, particularly around reusable rockets and commercial space ventures. The discussion centered heavily on Shubber’s criticism of current space projects, including Elon Musk’s data center plans in space, orbital mirrors for solar power, and space-based solar power systems. Shubber argued these projects were economically unfeasible due to launch costs, engineering challenges, and unrealistic timelines, using detailed calculations to demonstrate why proposed constellations would take decades to deploy rather than the claimed 5-year timeframes. The conversation also touched on NASA’s Artemis program, government debt concerns, and the challenges of space colonization, with Shubber expressing skepticism about many current space industry promises while acknowledging the long-term potential for space development.
Detailed Summary:
The Wisdom Team discussed the background of Shubber Ali, who joined the meeting late due to a family commitment. They shared memories of past encounters, including a NASA Ames event and Shubber’s work on the X33 “Adventure Star” project 25 years ago. The conversation touched on personal updates, including Shubber’s recent move from California to Maryland and his company’s location in Maine. The conversation ended with a brief discussion about potential future topics to cover, including data centers and reflecting mirrors, though the specific focus was not finalized.
David welcomed Shubber Ali to the Sunday Space Show to discuss the resurrection of Space Cynics, a blog and award system that Shubber had originally founded in the mid-2000s. Shubber explained that Space Cynics focused on critiquing outlandish claims made by space companies, particularly through their “Walking Eagle Award” given to companies making unrealistic promises. Shubber shared his background working at KPMG in the 1990s, where he managed a space consulting team that produced the first annual State of the Space Industry report in collaboration with SpaceVest and other partners. The discussion began to cover the history of RLV (Reusable Launch Vehicle) companies from that era, though the transcript ended before this topic was fully explored.
Shubber discussed the history of reusable rockets and space industry economics, highlighting how SpaceX’s success demonstrated the viability of reusable technology despite earlier failures like the Space Shuttle program. He criticized current space industry hype, particularly around data centers in space, explaining that such projects face significant challenges in physics, engineering, and timeline feasibility. Shubber provided specific calculations showing that deploying a large constellation of data center satellites would take decades, not the 5-year timeline often proposed, and emphasized that basic mathematical analysis could disprove many space industry claims.
Shubber expressed skepticism about Elon Musk’s business ventures, particularly SpaceX and the Boring Company, arguing that while Musk has vision and funding, the actual execution relies heavily on his team. Shubber criticized the overvaluation of AI companies, claiming there’s a significant bubble in the AI industry that will likely burst, with most AI applications being overhyped and overvalued. Philip disagreed, arguing that AI provides real value through productivity gains in areas like document drafting and research, though Shubber countered that these benefits are limited and often require significant human correction due to AI errors and hallucinations.
Next, the discussion focused on evaluating business proposals and technological ideas, particularly around supply and demand economics. Shubber explained his approach to identifying problematic business projections, emphasizing how increased supply typically leads to lower prices unless demand grows commensurately. The conversation also addressed Elon Musk’s Hyperloop concept, with AJ suggesting it was a bad idea without providing specific economic reasoning, which led to moderation intervention from David to keep the discussion focused on Shubber’s planned topics. The discussion concluded with technical considerations around satellite positioning and space-based solar power challenges.
We talked about the feasibility of space-based solar power, with Shubber and Phil both expressing skepticism about the technology’s practicality in the near term. Shubber emphasized engineering challenges including launch costs, construction of large structures at geostationary orbit, and the inability to service equipment there, while Phil focused on economic inefficiencies due to energy conversion losses and high launch costs. The conversation also covered the status of space hotels, with David sharing insights about Bob Bigelow’s withdrawal from the space hotel business following personal tragedy, and the group debated the value and hype surrounding NASA’s Artemis program, particularly regarding the SLS rocket and moon missions
The team discussed the Artemis program and NASA’s budget challenges. Shubber criticized the SLS project as inefficient and suggested opening it up to commercial competition. The conversation then shifted to the national debt and unfunded liabilities, particularly regarding Social Security. Shubber explained the financial challenges of the current system and expressed skepticism about proposed solutions like moving Social Security to a cryptocurrency system. The discussion concluded with a brief mention of orbital mirrors and their potential applications, though Shubber expressed doubts about their practicality and use cases.
The group discussed the feasibility and business case of using orbital mirrors to provide artificial sunlight, particularly for solar farms. Shubber and Philip analyzed the technical requirements, including the size of mirrors needed and the challenges of maintaining continuous sunlight. The discussion also touched on environmental impacts, including effects on agriculture and wildlife, and the long-term prospects for human space colonization, with Shubber suggesting that while space colonization may be necessary in the very long term, current public interest in returning to the moon remains limited.
The group discussed space tourism and commercial space missions. They clarified that while Axiom missions have taken approximately 16 people to the ISS, these were not traditional space tourists but rather business investors funding scientific research. The conversation then shifted to GRU Space, a company claiming to develop the first lunar hotel, though participants expressed skepticism about its credibility and media presence. The discussion concluded with Shubber outlining a framework for evaluating space business proposals based on physics, engineering, and economics principles.
The discussion focused on the challenges and realities of space technology investments, particularly regarding StarCloud’s satellite project. Shubber explained how companies like StarCloud secure funding through connections and hype rather than proven technology, contrasting them with older-style VCs like Ed Tuck who focused on legitimate due diligence. The conversation then shifted to nuclear energy, where Shubber expressed support for nuclear power while noting that regulatory and construction challenges, rather than technical feasibility, are the main obstacles. The discussion concluded with a debate about the role of space advocates, where Shubber emphasized the importance of balancing ambitious vision with realistic timelines to maintain credibility and avoid damaging the broader space industry through unwarranted hype.
The declining quality in journalism and scientific reporting was a topic. Shubber shared his experience of discovering that even respected publications like Scientific American contained inaccurate information, leading him to question the credibility of mainstream media. David described how his experience as a parent of a child with cystic fibrosis revealed widespread miscommunication between journalists and scientists, with researchers confirming that journalists often misunderstood their work. The discussion concluded with Ajay expressing concern about increasing dishonesty in scientific research, though Shubber clarified that the core scientific method remains sound and that issues arise when researchers prioritize agenda-driven outcomes over objective truth.
The group discussed the challenges of modern engineering and space technology, particularly focusing on SpaceX’s Starship development and the complexity of creating new products compared to historical examples like the Model T. Shubber mentioned his plans to write an upcoming OP-ed about space exploration and financial concerns, comparing the current situation to Britain before the fall of Singapore. The conversation concluded with a discussion about the likelihood of experiencing the Kessler syndrome by 2050, with participants expressing varying levels of optimism about humanity’s ability to prevent such a scenario.

Bob Zimmerman, # 4594, May 26, 2026
Quick Summary:
This Space Show program focused on NASA’s announcement of a restructuring plan for the Artemis lunar program led by Isaacman, which includes multiple unmanned lunar lander missions and the establishment of a lunar base by 2028. Bob detailed how NASA is relying heavily on private companies rather than building hardware internally, with contracts awarded to Blue Origin, Astrobotic, Intuitive Machines, and Firefly for missions starting as early as late 2023. The discussion covered the competitive landscape of commercial space stations, with VAST, Starlab, and Axiom leading the market, while Sierra Space’s Orbital Reef partnership with Blue Origin appears to be struggling. The conversation also addressed SpaceX’s Starship development progress, with participants debating whether SpaceX would attempt a double catch of both booster and ship on their single launch tower before building a second tower. The show concluded with a discussion about the political and cultural challenges facing space exploration, with participants weighing optimistic versus pessimistic views about the future of commercial spaceflight and space policy.
Summary
Bob discussed NASA’s recent press conference announcing details of its Artemis lunar exploration program, including contract awards and mission plans. The program involves multiple private companies launching lunar landers and rovers to the South Pole region, with the first three missions already scheduled before the end of 2023. Robert noted that while the program is ambitious with plans for up to 20 launches and 25 landings by 2028, it relies heavily on private sector development rather than NASA-built hardware, with Blue Origin receiving significant contracts including two new awards totaling $188 million.
Bob discussed Blue Origin’s lunar landing plans, expressing skepticism about their timeline of 20 landings by 2028, particularly given their reliance on Blue Origin and the challenges with their New Glenn rocket. The group examined a map shown during a press conference about a potential lunar base location near Shackleton Crater, with Joseph identifying a similar crater field in the area and Robert noting the lack of specific location details in the presented map. The discussion concluded with speculation that NASA might be deliberately withholding specific location information to protect potential landing sites from competitors, particularly China.
NASA’s lunar exploration plans were talked about, explaining that missions will focus on scouting and engineering work to prepare for future manned landings and a lunar base. He also revealed that NASA awarded SpaceX additional crew launch contracts through 2030, which he interpreted as effectively ending Boeing’s Starliner program due to lack of funding for further development. Joseph clarified that NASA is not obligated to provide additional funding to Boeing until they successfully complete their original cost-fixed contract.
Bob focused on the current status of commercial space stations, ranking five active projects and noting that while there are market opportunities for ferrying services, Boeing’s Starliner faces challenges due to Boeing’s poor management. He explained that Dream Chaser’s status remains uncertain, with recent delays and incomplete ground testing raising questions about its viability. Robert also provided an update on the five commercial space stations, ranking them and noting that while some projects like VAST and Starlab show promise, Sierra Space’s Orbital Reef partnership with Blue Origin appears to be dormant.
He also explained that private space stations will outperform the ISS by allowing commercial research to produce saleable products on Earth, unlike the ISS which is restricted to non-commercial research. He discussed how NASA’s historical ban on commercial space operations had damaged the American launch industry, citing the example of pharmaceutical research that was halted after the Challenger accident. The group agreed that private companies will own and operate the new stations while NASA purchases services as a customer, representing a shift toward a more capitalist model in space operations.
The group discussed SpaceX’s lack of response regarding NASA’s lunar program, with our guest explaining that SpaceX is focused on manned missions rather than these specific missions and needs to be careful due to their upcoming IPO. The conversation then shifted to comparing NASA’s bureaucratic processes with private space station initiatives, with participants noting how private stations are more flexible and business-friendly compared to the complex requirements of getting experiments on the ISS. Bob explained how top-down bureaucratic systems, like the Soviet model, tend to fail due to lack of competition and innovation, while competitive market systems drive better results.
Bob did address the historical shift from government-led to commercial space exploration, highlighting how SpaceX and commercial satellite businesses proved that profit could be made in space despite initial skepticism. He explained how NASA’s Mars exploration programs have historically been science-focused rather than colonization-focused but noted a recent shift toward engineering-based lunar exploration with the VIPER lander program. The discussion concluded with updates about ULA’s Vulcan rocket program, which is currently grounded due to nozzle failures in Northrop Grumman’s solid rocket boosters, though static fire tests suggest potential solutions may be in development.
The group discussed ULA’s challenges with satellite launches, particularly Amazon’s delayed satellite deployment and ULA’s dependency on strap-on boosters for their Vulcan rocket. Joseph clarified that the NG-4 mission would be a LEO launch carrying 26 satellites, though the rocket’s payload capacity might be limited without boosters. The discussion also covered SpaceX’s Starship development progress, with Joseph estimating 3-4 flights this year before a second launch tower becomes available in Q4, and the team debated whether SpaceX would attempt a double catch on their current tower or wait for the new one to recover both booster and ship.
The Wisdom Team also discussed Elon Musk’s management approach and scheduling practices, with Robert explaining that Musk sets realistic but challenging timelines that engineers can trust. The conversation then shifted to Starlink satellite services, with Bob sharing his positive experience using the service despite minor performance issues during house painting. This part of the discussion concluded with my asking Bob for his guess on the political risks facing space commercialization efforts given current uncertainties and realities in the country today.
Bob did discuss his perspective as a historian on current societal challenges, presenting both pessimistic and optimistic views of the future. He compared the current political climate to H.G. Wells’ time in 1939 and noted that while there are concerning trends, he remains hopeful about society’s resilience and ability to correct course. The discussion touched on concerns about data centers, with both David and Joe sharing local experiences about public opposition to data center development, which Bob attributed partly to ignorance and manufactured comments on social media.
The team discussed opposition to data center construction, with Joe explaining that while some opposition may be driven by Chinese influence, much of it stems from emotional responses and partisanship rather than rational concerns. Bob emphasized the need for more thoughtful and rational discourse about data centers, distinguishing between legitimate questions about their impact and emotional reactions. Joe clarified that modern data centers use less water than older designs, but the rapid scale of proposed construction (80 gigawatts) far exceeds current grid capacity (40 gigawatts annually), making many planned projects unlikely to be built. Bob concluded that the opposition to data centers on Earth could actually benefit the space industry by driving demand for orbital data centers, which would help develop the rocket industry.
The group went on to talk about water requirements for data centers, with Ajay explaining that while traditional nuclear reactors require significant water for cooling, molten salt reactors would not need water for this purpose. The conversation then shifted to political concerns about constitutional issues, with John Hunt warning about potential constitutional collapse and Bob responding with a balanced historical perspective. The conversation ended with technical discussions about SpaceX’s Starlink V3 satellites, including their weight and bandwidth capabilities compared to previous versions.

The Space Show Presents Paul Warley, CEO of Ascent Solar, Friday, 4-17-26
Quick Summary:
The Space Show featured Paul Worley, CEO of Ascent Solar, discussing their flexible thin-film solar technology. Paul explained that their CIGS (Copper Indium Gallium Sulfide) panels are lightweight, rollable, and designed to fit specific areas, offering 12.5-14% efficiency and costing $35-70 per watt compared to silicon’s $3-10 per watt. The panels have been tested in space and can withstand radiation better than silicon, with applications including satellites, drones, high-altitude platforms, and underwater systems. Paul noted their panels can be deployed and rolled up multiple times, with TRL9 certification from a previous space mission. The company is publicly traded on NASDAQ as ASTI and focuses primarily on DoD and commercial space markets, with plans to expand in MEO, GEO, and lunar applications in the coming years.
Detailed Summary:
Our program focused on technical discussions about space missions and power requirements. Paul explained different power levels for various orbital ranges, noting 450-600 watts per kilogram for MEO and GEO missions, and 150-250 watts per kilogram for lower orbits. The group discussed the format of an upcoming 60-minute space show, with participants introducing themselves and their backgrounds. Technical issues with audio echo were identified but not fully resolved before the end of the meeting.
Paul explained the cost and efficiency differences between various solar panel technologies for space applications. He clarified that gallium arsenide panels cost $250-350 per watt, silicon panels cost $3-10 per watt, and their SIGS (Copper indium gallium sulfide) technology costs $35-70 per watt. Paul also described how their technology uses a different coating (XBR) for underwater applications, allowing panels to be submerged at 500 meters and recharge on the surface.
Paul further discussed the development and specifications of their flexible solar panel technology, highlighting its advantages over traditional silicon wafers, including being 3-10 times lighter and providing roughly 4 times the power. The discussion covered the technology’s performance in high-pressure environments, manufacturing considerations, and potential applications in space, including lunar manufacturing and satellite deployment. Paul mentioned having a SpaceX founder on his advisory board and noted their current customers include a communications satellite company, with plans for manufacturing in space, as well as potential applications in drones, HAPS, and underwater systems.
Paul discussed their company’s solar panel technology, explaining that if a panel is damaged by space debris, electricity can still flow around the damaged area. He confirmed they are in talks with multiple space companies, though he declined to name specific clients. When asked about operating temperatures, Paul clarified that their panels can operate between -100C to +100C in space conditions, though he couldn’t specify the exact temperature without cooling systems. The discussion ended with Paul highlighting their product’s key advantage of faster delivery times compared to traditional gallium arsenide panels, though he didn’t complete the specific timeline comparison.
Paul discussed the efficiency of their flexible solar panels, explaining they measure between 12.5% and 14% efficiency in secondary cells. Marshall inquired about the durability of rolling up the panels, to which Paul confirmed they can be rolled up hundreds or thousands of times without damage, citing their TRL9 rating achieved through underwater testing. Paul also mentioned their product is patented and not restricted by ITAR, though they primarily market to Europe and India rather than China or other restricted regions.
Paul talked about his company’s solar product, highlighting its durability and competitive advantage over Chinese alternatives in the consumer market. He explained that while the product was previously used in camping and military applications, current focus areas include DOD commercial applications, space, and potentially drones. Paul noted that while residential rooftop installation is financially viable, it’s not part of their current strategy due to reinforcement requirements for buildings. The discussion concluded with an unasked question about cell density per square meter from John Hunt, which was not answered in the provided transcript.
Deployable solar panel technology, explaining that their panels can produce power at 60% angle while most silicon panels require 30-40% angle for power generation. He described different deployment mechanisms including roll-out systems and origami structures, noting that cost and mass of the support system are significant factors. Paul also mentioned that their technology is currently too expensive for widespread residential use, with installation costs being a major barrier, and that 40% of roofs would require reinforcement.
We covered ongoing R&D efforts to improve product efficiency and reduce waste, including work with perovskite coatings and a collaboration with a company that has developed 400 patents around perovskite technology. The team conducted initial space testing with different FEP thickness coatings, though the sample size was too small for definitive conclusions. Paul mentioned that additional radiation and atomic oxygen testing would be conducted in the next 2-3 months, and he expected data from the Novi satellite launch on SpaceX’s rocket within 2-3 weeks, including information about deployment and space debris impact.
The meeting also focused on discussing Paul’s space solar panel technology company, ASTI, which is publicly traded on NASDAQ. Paul explained that while the company receives about one legitimate space-related business inquiry per week through their website, they typically require NDAs to share technical details about their solar panels, which can withstand higher temperatures and radiation than traditional silicon panels. The discussion revealed that ASTI’s competitive advantage lies in the flexibility of their panels, allowing them to outperform silicon panels in certain curved or complex applications. Paul noted that while the company is well-funded and manufactured-ready, the next major power push in space is expected in the third and fourth quarters of next year.

Detailed Summary:
SpaceX Starship Launch Discussion
The group discussed SpaceX’s recent Starship launch, which John described as a partial success with significant technical challenges including an engine outage that caused the booster to deviate from its course. David praised the high-quality camera work and photography during the launch, while Dr. Sherry noted that SpaceX itself considered the mission a success and emphasized their approach of learning from mistakes. The team also explained the satellite ejection mechanism used in the launch, with Charles and Robert providing details about how the satellites were deployed from the rocket.
The group discussed SpaceX’s Starship Flight 12 (IFT-12), with participants evaluating its significance for future Artemis missions. Bob explained that while the flight was important for testing new engines and systems, it wasn’t critical for SpaceX’s overall success, particularly given their upcoming IPO and existing Starlink revenue. The discussion highlighted the technical challenges involved in the flight, including new Raptor 3 engines and a rebuilt launch pad, with participants agreeing that the flight achieved its main objectives of reaching orbit and conducting necessary tests.
The Wisdom Team discussed the recent Starship test flight, comparing it to SLS development and emphasizing that the technologies are not comparable due to different approaches and goals. David defended SpaceX’s methodology of learning from failures, while Ajay highlighted specific technical issues with the first stage during the test. The discussion included observations about engine problems and a puncture in the tile, with participants noting that this is part of the development process for new technology.
The group discussed the recent SpaceX Starship test flight, with Dr. Ajay clarifying that one engine blew up before separation, causing other engines to shut down due to fuel sloshing. Phil expressed concerns about the program’s timeline, arguing that SpaceX is not on track to meet the goal of reaching the moon within a couple of years, while Robert countered that abandoning the current approach would only cause further delays. The discussion concluded with Dallas defending the mission’s success in achieving its suborbital trajectory goals, though Phil maintained that the program has not yet proven its ability to deliver the required 100 tons of payload to orbit.
The team discussed SpaceX’s satellite deployment program, with Marshall clarifying that dummy satellites weighed about 2 tons each but Phil found conflicting information suggesting 17 tons total for 22 satellites. The discussion then shifted to refueling capabilities, where Doug shared insights from a leading researcher who estimated a 50% chance of success on the first attempt and near 100% on the second attempt for propellant docking and transfer. The conversation concluded with Ajay noting that while Progress has done fuel transfer with storable fuel, cryogenic fuel transfer remains untested in orbit, though SpaceX had previously demonstrated cryogenic propellant transfer during IFT-10.
The group discussed SpaceX’s development of in-orbit refueling capabilities, with Dallas sharing details about their 2008 demonstration using vapor-cooled skins and a crawl cooler from Criari. The discussion focused on comparing SpaceX’s progress with Blue Origin’s approach, with Robert noting that while SpaceX has outlined plans for a several-week refueling mission this year involving two Starship launches, Blue Origin’s development pace remains slower. The conversation concluded with debate about propellant requirements for lunar missions, with Dallas explaining that the HLS mission would need approximately 40 tons of propellant for the Gateway and lunar lander in the lunar vicinity.
Phil suggested that NASA should design the optimal lunar lander and then assign contracts to commercial companies like Boeing or SpaceX for manufacturing, while also working to reduce the cost of SLS rockets through mass production. Robert clarified that NASA’s investment in SpaceX’s Starship program is minimal compared to SpaceX’s private funding, which includes $12 billion raised for Starlink and an expected $75 billion from an IPO. The discussion highlighted concerns about Starship’s timeline and feasibility, with participants noting that alternative approaches using existing technology like SLS and a modified lander could potentially be faster than Starship development, though still facing significant challenges.
Robert discussed the challenges with NASA’s rocket development programs, highlighting that despite being 16 years since launch, they have only launched twice and suggesting that competition from multiple companies would be beneficial. Phil argued that NASA should handle advanced projects internally due to their track record of successful first-time launches, while Dallas clarified that NASA did not design the SLS but served as system integrator. David raised concerns about safety risks in human spaceflight programs, citing a former Artemis team engineer’s warnings about discontinuity in systems engineering when switching between commercial companies, which Marshall supported by noting that most bugs occur at interfaces between different components or companies.
The group discussed software engineering interfaces and their impact on system safety, particularly comparing Apollo and Artemis programs. Marshall and Ajay explained that while multiple companies building different components can create interface challenges, proper system engineering and testing can mitigate these risks. Robert emphasized that Artemis’s current issues stem from lack of overall NASA-designed architecture and distributed ownership, suggesting NASA should consolidate components and hire companies to build major components with fewer interfaces. Doug cautioned against attributing 90% of problems to interfaces alone, noting that known issues in NASA’s culture contributed to previous shuttle program losses.
The discussion focused on comparing NASA’s Apollo-style approach with SpaceX’s commercial approach for returning to the moon. Doug and Charles argued that the commercial approach using Starship offers better long-term sustainability and permanence on the moon compared to the Apollo-style urgency-driven approach using SLS and Orion. Philip countered that Starship is not necessarily the permanent solution and that a racal departure from rocket technology might be needed for true permanence. The conversation also highlighted that SpaceX’s Starship development represents a smaller portion of their overall investment compared to their other projects like Starlink, with Starship serving as a transportation system to support broader capabilities.
The group discussed the evolution of chemical rockets and reusability, with Phil and Doug clarifying that full reusability is not a revolutionary change compared to the space shuttle. David challenged critics like Phil and AJ to support the current Artemis program rather than continuously criticize it, asking what constructive role they could play given the program’s commitment to Starship and Artemis missions. Ajay expressed support for the Artemis program overall but raised concerns about Starship’s size and propellant fraction requirements, suggesting it should be reduced to about one-third its current size for lunar missions. Phil shared insights from his recent presentation at Ascend, noting that NASA engineers lack access to critical technical details about Starship’s development, similar to the broader public’s understanding of the program.
The group discussed concerns about NASA’s involvement and insight into SpaceX’s Starship program, with Philip expressing concerns that NASA’s team lacks sufficient information to properly assess Starship’s performance and safety. The discussion revealed that while NASA has embedded engineering teams with SpaceX and extensive visibility into various aspects of development, they don’t have complete control over architectural decisions. The conversation ended with John mentioning SpaceX’s improvements to the launch site and Raptor 3 engine, and Sherry praising the video footage of Starlink satellites in space.
The group discussed SpaceX’s achievements and role in the space industry, with participants praising their rideshare and Starlink initiatives while expressing concerns about relying too heavily on Starship for the Artemis program. Phil suggested reassessing NASA’s lunar landing strategy by considering alternative solutions like using Falcon Heavy or smaller landers from companies like Dynetics or Blue Origin. The conversation ended with Robert promoting an upcoming Space Show discussion and David reflecting on Memorial Day, thanking veterans for their service and contributions to space exploration.

The Space Show Presents Gary Barnhard, Friday, May 8, 2026
Quick Summary:
The Space Show discussed space data centers with Gary Barnard, who explained the engineering challenges and potential solutions for placing data centers in space. Gary emphasized the importance of treating space data centers as combined heat and power problems rather than just power generation issues and highlighted how SpaceX’s Starlink constellation already represents an existence proof of space-based computing. Kevin Berry and Dr. Suzanne Sincavage also joined to discuss their work on space infrastructure and biological data storage in space, with Kevin presenting on space solar power at the upcoming NSS ISDC conference. The discussion included technical details about thermal management, launch costs, and the potential for Starship to revolutionize space transportation economics, though some participants expressed skepticism about certain engineering claims made during the conversation.
Detailed Summary:
David Livingston introduced the topic of space data systems and welcomed Gary Barnard, president of Extraordinary Innovative Space Partnerships, to discuss the subject. Gary discussed the evolution of space solar power from niche applications to potential space infrastructure that could serve a range of customers. He emphasized the importance of balancing enthusiasm with practical considerations, particularly regarding the fundamental laws of thermodynamics. Gary highlighted that systems engineering across disciplines is crucial for understanding the problem space and potential solutions, rather than focusing solely on technical details.
Gary discussed the challenges of powering a data center in space, explaining that while space solar power systems are possible, they require massive radiators and don’t scale easily. He emphasized that viewing the problem as a combined heat and power issue, rather than just power generation and waste heat disposal, could make it more feasible by utilizing waste heat for other purposes like data center cooling and habitation. When asked about trusted sources for information on space-based solar power, Gary expressed skepticism about NASA’s report, noting that it was rewritten to reach a predetermined conclusion that space solar power wouldn’t be viable.
Gary discussed the concept of “frog kissing” in relation to evaluating promising but potentially untractable ideas, using data centers in space as an example. He shared his analysis of thermal balance models and radiation environments, noting that recent experiments on the ISS showed radiation effects were less severe than initially anticipated. When asked about SpaceX’s claims regarding AI data centers in space, Gary expressed trust in SpaceX’s engineering capabilities, particularly in areas he understands well, while acknowledging his expertise spans multiple disciplines beyond just thermal systems.
Gary discussed SpaceX’s evolution in satellite technology, particularly with Starlink, highlighting their progress from providing basic service to competing in the quality market. John Jossy proposed conducting a systems engineering analysis of Starlink’s design and scaling it to space data centers, which Gary expressed interest in. John shared findings from Mach 33’s analysis on scaling from 20 to 100 kilowatts, concluding that radiative cooling is not a physics blocker for this transition. Gary emphasized the importance of optimizing thermal mass and heat management in space data centers to make them practicable.
Gary discussed the challenges and economics of power generation in space, highlighting the cost-effectiveness and resilience of different systems like photovoltaic and solar dynamic technologies. He emphasized the complexity of implementing new technologies in space missions and the potential for a paradigm shift as launch costs decrease, allowing for better optimization of functionality over size, weight, and power constraints. Bill mentioned SpaceX’s IPO insights on orbital data centers, noting their dependency on Starship for economic viability.
Gary further discussed the economic challenges of orbital data centers, suggesting that improvements in space transportation, particularly with Starship, could make them viable within three orders of magnitude. He emphasized the need for prototyping and testing early systems, highlighting the complexity of simulating space environments. Gary also addressed terrestrial data center limitations, noting that current ground-based systems face supply chain constraints and environmental challenges, which could drive demand for space-based alternatives. The discussion touched on the need for advanced modeling to address the dynamic nature of power and data transmission in space-based systems.
Our guest discussed the technical feasibility and challenges of space data centers, noting that while SpaceX’s Starship could significantly reduce launch costs to low Earth orbit, building scalable power systems and managing operations would require new frameworks for human-robot collaboration. He mentioned his ongoing research since the 1980s on n-dimensional interaction problems and indicated that his latest work, including a presentation at IAC 2025 in Sydney, would be made available online through the XISP Inc. website and the space show.
Kevin Berry discussed the feasibility and economics of space data centers, highlighting SpaceX’s Starlink constellation as an existing proof of concept with 300 megawatts of collection in orbit and 10,000 satellites. He explained that early 2030s data center construction in space could become more cost-effective than ground-based construction due to expected decreases in space hardware and launch costs. Kevin noted that while SpaceX currently has a significant cost advantage over competitors like Blue Origin, the space data center market remains in early exploration stages with potential for significant growth as costs continue to decline.
Dr. Suzanne Sincavage introduced her work on building a secure biological data repository, particularly focusing on DNA collection from Earth species for future astrobiology research and space-based biological studies. Kevin and Gary discussed space solar power systems, with Kevin explaining how Starship technology represents a paradigm shift from austerity-minded space design to industrial-scale manufacturing approaches. The group also discussed combined heat and power systems for space applications, though Phil very strongly expressed skepticism about some of the proposed engineering approaches being suggested by Gary. David announced he would miss the upcoming ISDC conference due to it coinciding with his 80th birthday, and the team discussed potentially featuring both Kevin and Suzanne on separate Space Show episodes about their respective ISDC presentations. While not part of this summary, The Space Show Wisdom Team continued discussing the subject off air with Phil strongly advocating against some the engineering proposals suggested by Gary regarding getting rid of the heat generated by an in-space data center. Perhaps on our next OL program if Phil joins that discussion, I can ask him to elaborate on his position regarding the engineering ideas presented during this discussion.

The Space Show Presents Author & James Van Laak re his book “To See Far - Conflict and Cooperation on the Space Frontier” from Tuesday, April 14, 2026
Quick Summary:
This was a West Coast Space Show program hosted by David Livingston featuring author Jim Van Laak, who discussed his book “To See Far: Conflict and Cooperation on the Space Frontier.” Jim shared his experiences working on the International Space Station partnership with Russia during the 1990s, emphasizing the challenges of overcoming Cold War tensions and establishing cooperation between former adversaries. The discussion covered NASA’s current challenges, particularly regarding the Artemis program and SpaceX’s Starship development, with Jim expressing concerns about NASA’s lack of complete systems understanding due to the commercial service contract approach. The conversation also touched on broader societal issues, with Jim presenting a proposal about addressing global challenges through systems thinking and suggesting humanity may face significant challenges within 50 years.
Detailed Summary
Our Space Show team discussed James’s current role as a senior engineering consultant on the Artemis program, where he expressed concerns about schedule pressure and safety risks. We went on to the introductions where James discussed his book about conflict and cooperation on the space frontier, particularly focusing on his work with the former USSR on the ISS program.
James shared his background as a Vietnam War veteran and pilot who later became one of the original seven leaders of the International Space Station (ISS) program in 1993. He discussed the challenges and tensions involved in establishing the cooperative program with Russia, highlighting how the partnership evolved from a survival instinct into genuine respect. When asked about the upcoming de-orbiting of the ISS, James acknowledged the sadness of its retirement but explained that the orbital debris risks make it impractical to keep it operational or reposition it as a museum. David expressed concerns about commercial space stations not matching the safety and redundancy of the ISS.
Jim discussed his extensive background in aviation and emphasized the importance of humility in leading the space business, noting that many entrepreneurs lack this characteristic. He shared insights from the Soviet Union era, highlighting the challenges of working with difficult partners and the necessity of cooperation for the success of the space station program. He explained that the partnership with Russia was learned through practical experience rather than formal guidance, and he noted that technical collaboration required learning on the job without diplomatic involvement.
Our guest shared his experience working on the Space Station program, particularly highlighting a meaningful meeting with a Russian chief engineer in 1993 where treating the colleague with respect led to a productive collaboration. He explained that while early interactions with Russian colleagues presented challenges, the program eventually developed a collaborative culture that has become normalized across both organizations. Marshall commented on the common challenge in software engineering of developing good solutions but facing difficulty in getting them accepted by others, which James acknowledged as a familiar issue in the space program.
Jim talked about his experience working on the Space Station Freedom project, where he identified significant reliability issues with the attitude control system. He found that the probability of the system functioning across a 15-month period was only 35%, with a 65% probability of failure. This concern gained attention during the 1993 redesign when Bill Shepard became the transition program manager, leading to James being brought onto the ISS team to address these issues. James also shared his background in aviation, including a personal experience with an aircraft fire at age 19, which motivated him to understand the causes of machinery failure and human decision-making errors.
His experience with NASA over nearly 40 years focused on sharing insights from his book “My Wife’s Creation” about the importance of space exploration. He expressed disappointment with NASA’s current Artemis program, particularly criticizing the lack of historical knowledge and the decision to have humans first experience the Starship during the moon landing mission without proper flight testing protocols. James noted that while some NASA personnel excel at seeing far and considering the larger picture, others tend to be one-trick ponies focused on specific solutions without broader perspective.
James discussed the challenges in NASA’s decision-making process, arguing that poor leadership over the past 15 years has led to suboptimal solutions due to a lack of global perspective and systems understanding. He highlighted the issue of handling flammability in the cabin atmosphere as an example of how experts in different fields struggle to coordinate their efforts effectively. James emphasized the need for a systems engineer who can understand the interconnections between technical and human dimensions, rather than having experts who focus only on their specific areas of expertise.
The group discussed leadership and management styles, particularly focusing on Elon Musk’s role at SpaceX and James’s experience leading a team of several thousand people during the space station era. James shared insights about his role as a coach and team captain, emphasizing how technical decisions were made collaboratively but ultimately required his final authority. The conversation concluded with David highlighting current external constraints on NASA, including congressional oversight and proposed budget cuts to the science budget, which he noted work against the vision of space exploration for all.
Our guest talked about how NASA could better manage constraints and Congress’s role in space programs. He explained that effective NASA leadership is crucial in articulating technical requirements to Congress, who ultimately relies on NASA experts for guidance. The conversation then shifted to analyzing Starship’s compliance with the rocket equation, where James argued that using Starship for lunar missions would involve unnecessary complexity and risk due to its mass ratio requirements. John added that using Starship as a lunar lander may have been more of a political decision than a technical one, and James concluded by highlighting the importance of reliability in spacecraft design, referencing Apollo’s simple ascent engine as an example of effective engineering.
James expressed concerns about NASA’s limited understanding of SpaceX’s Starship system due to proprietary information restrictions in the commercial service agreement. He highlighted that NASA’s current level of access and technical mastery is significantly lower compared to previous generations of vehicles, raising questions about the reliability and performance claims. James emphasized that while he supports SpaceX’s efforts, the decision to rely on commercial contractors represents an untested approach in this domain, making the outcome uncertain.
The group discussed space technology and engineering approaches, with James sharing his perspective on traditional systems engineering versus newer approaches like SpaceX’s Starship. James agreed to write a review for the Evidence Ledger regarding Starship claims. The conversation shifted to broader societal questions about space exploration’s purpose and value, with James expressing doubt about human society surviving 50 years due to current trends in technology and behavior. The conversation ended with plans for an upcoming radio appearance where Philip and Joe would be guests discussing Artemis and lessons learned.

Quick Summary:
The Space Show hosted science journalist Rahul Rao to discuss his new book on nanotechnology, focusing on applications in space and other fields. Rao explained that while humans have been using nanoscale materials for centuries, the field as we know it began developing after World War II, with significant breakthroughs in the 1980s and 1990s including the discovery of carbon nanotubes in 1991. The discussion covered both promising applications like medical nano surgery, spacecraft coatings, and environmental cleanup, as well as current challenges including material defects and scaling issues that limit practical implementation. While some applications like enhanced carbon fibers and aerospace coatings are already happening, more ambitious uses like space elevators remain in the future timeline, with widespread implementation likely in the 2030s rather than the near term. The conversation also addressed potential risks including environmental pollution from nanoparticles and weaponization concerns, though these were deemed less immediate than current technical challenges.
Summary
Rahul Rao, a science writer and journalist, discussed his focus on nanotechnology and space topics, highlighting the common use of nanomaterials in various scientific and engineering areas. He explained the historical development of nanotechnology, noting its origins in the post-World War II era and significant advancements in the 1980s and 1990s, including the discovery of carbon nanotubes in 1991. Rahul also addressed the current and potential future applications of nanotechnology, including the use of nanomaterials and the possibility of creating molecular-scale machines, though the boundaries of such advancements remain uncertain.
David discussed his experience with the space elevator concept, noting its popularity in the early 2000s but questioning its current feasibility. Rahul explained that while carbon nanotubes and graphene are being developed at large scales, the materials remain too defective for a space elevator. The conversation highlighted the distinction between carbon nanotubes and carbon fiber, with Philip clarifying that they are different technologies.
Phil explained the differences between carbon nanotubes and carbon fiber, noting that while carbon fiber is widely used in industries like aerospace and sports equipment, carbon nanotubes remain challenging to scale up effectively due to manufacturing limitations. Rahul discussed his interest in nanotechnology, highlighting its diverse applications beyond ambitious concepts like space elevators, including practical innovations like mRNA vaccines and CO2 storage using MOF nanomaterials. When asked about technology readiness levels, Rahul indicated that while the CO2 storage application is still in laboratory stages, similar substances are being tested in pilot projects. Marshall mentioned his interest in 2DPA-1, a two-dimensional polymer with properties similar to steel, though development in the past four years has been limited to improving manufacturing methods.
Rahul discussed the timeline challenges with nanotechnology materials, comparing them to historical examples like aluminum, which took decades to develop into widely used materials. He explained current nanotechnology research areas, including nanoparticles for targeting disease pathogens and nanoscale tools for medical applications like cancer treatment. When asked about self-healing cables for space elevators, Rahul was not aware of any proven or published research on this specific technology, though he noted it was mentioned in discussions. David shared information about self-correcting undersea cables from the 1990s that could reroute signals around damage, though these are now losing economic value due to satellite technology like Starlink.
Rahul discussed current and future applications of nanotechnology, highlighting medical applications as likely to receive significant attention in the coming years. He mentioned the development of enhanced carbon fibers with carbon nanotubes for use in aircraft and spacecraft coatings, as well as the potential for using carbon nanotubes in small electronics within the next decade. Rahul also explained that quantum dots, another form of nanotechnology, are being used in QLED televisions and discussed the challenges in producing defect-free carbon nanotubes. When asked about potential “nano nightmares,” Rahul identified environmental pollution and the risk of nanoparticles entering the human respiratory system as significant concerns.
Rahul explained that incidental nanomaterials, which naturally exist, pose less immediate hazard than engineered nanomaterials that might escape into the environment. John Hunt raised concerns about potential misuse of nanotechnology for weaponry, though Rahul considered this a less pressing issue than environmental pollution. Marshall inquired about the relationship between nanoparticles and radiation, to which Rahul responded he was not aware of specific issues but acknowledged the potential intersection. Rahul outlined several applications of nanomaterials in space, including thermal insulation, heat shields, and nanoparticle-enhanced propulsion, suggesting these could emerge within the next 5-10 years.
Rahul discussed the current state and future potential of nanomaterials, particularly carbon nanotubes and graphene. He explained that while nanomaterials are already being used in aerospace applications and will continue to grow in the next five years, broader applications like those in automotive industries or advanced tires are likely still decades away. Rahul noted that increased private sector interest and startup activity could drive progress, though he expected any impact to be gradual rather than revolutionary. The discussion also covered potential applications in space exploration, environmental engineering, and construction materials, with Rahul emphasizing that while theoretical possibilities exist, practical implementation timelines remain uncertain.

The Space Show featured a discussion with Dr. Robert Zubrin about NASA’s Artemis program and Mars exploration plans. Dr. Zubrin criticized the current Artemis architecture as incoherent, comparing it unfavorably to Apollo’s purpose-driven approach, and proposed a “Starship plus Starboat” configuration for both lunar and Mars missions. He expressed concern about proposed cuts to NASA’s space science program and criticized NASA Administrator Isaacman for supporting these reductions despite earlier opposition. The discussion covered technical aspects of mission architectures, including the challenges with Starship’s payload capacity and the potential for one-way cargo delivery to Mars. Dr. Zubrin also mentioned the Mars Technology Institute’s efforts to develop technologies needed for Mars settlement, rather than just travel.
The meeting focused on discussing NASA’s space science program and the Artemis mission. Bob Zubrin highlighted concerns about a second attempt by the Trump administration to significantly cut the NASA Space Science Program, which he characterized as a destructive effort rather than just negotiation tactics. Robert discussed NASA’s recent progress with the Artemis program, comparing it to the Apollo 8 mission. He explained that while the current flight was less ambitious than Apollo 8, the Artemis program lacks a coherent mission architecture due to its reliance on five independent programs and systems that do not fit together. Robert highlighted specific issues with the SLS rocket and Orion capsule, noting their inability to support lunar missions as intended, and explained SpaceX’s proposed solution using Starship, which would require 14 launches for a complete mission to the moon and back.

The Space Show Presents David Eicher, 4525, 4-3-26
Quick Summary:
This Space Show discussion featuring David Eicher, editor emeritus of Astronomy Magazine, who shared insights about the current state and future of astronomy, space exploration, and scientific discovery. The conversation covered the rapid pace of astronomical discoveries in recent decades, challenges posed by satellite light pollution for both amateur and professional astronomers, and the philosophical aspects of science education. Eicher discussed the likelihood of extraterrestrial life and the technical challenges of detecting it, while also addressing the prospects of human space exploration and settlement. The panel explored topics including the impact of AI on scientific work, the potential for large space telescopes, and the role of private citizens in funding space missions, with Eicher noting that future discoveries about dark energy and dark matter could revolutionize our understanding of the universe.
Detailed Summary:
David Eicher discussed the current state of public knowledge about astronomy and space exploration. They noted that many people, including healthcare professionals, lack basic understanding of space topics and recent events like rocket launches. The conversation highlighted concerns about the adequacy of science education in the country, with particular emphasis on the low awareness of NASA’s activities among younger generations who weren’t alive during the Apollo missions. The discussion also touched on the challenges of scientific literacy and critical thinking in society.
Mr. Eicher, editor emeritus of Astronomy Magazine, discussed the complementary nature of Astronomy Magazine and Sky & Telescope, explaining that they served different markets with Astronomy focusing on beginners to intermediates while Sky & Telescope targeted more advanced readers. Eicher attributed the current rapid pace of astronomical discoveries to a combination of factors including more people working on finer details, improved instruments and telescopes, both in space and on the ground. The discussion highlighted significant advances made in recent generations, including better understanding of the universe’s age, the Big Bang theory, and the number of galaxies, though mysteries remain about dark energy and dark matter.
We discussed the decline in science education through media, particularly television, since the 1960s. and explored how people increasingly rely on authority rather than independent thinking or scientific methods to understand the world. The conversation then shifted to the impact of satellite proliferation in space on astronomy, with Eicher expressing concern about how satellite trails affect professional astronomical research and wide-field imaging. While acknowledging that orbital telescopes might become necessary to avoid light pollution issues, Eicher noted that this would not help amateur astronomers on Earth.
The discussion focused on challenges for radio astronomy due to increasing orbital assets and satellite traffic, particularly in the context of a proposed cislunar economy. David Eicher noted that while moving radio telescopes to the far side of the moon or deep space remains a viable long-term solution, these approaches would be extremely expensive and require significant government and private sector investment. The group also discussed current funding challenges for science, with Bill and David Eicher acknowledging that while Congress maintained NASA and NSF science funding despite proposed cuts, the overall climate for scientific investment remains difficult. Marshall presented calculations showing how a large telescope in orbit using Starship technology could significantly enhance light-gathering capacity compared to current telescopes, though Eicher emphasized that such ambitious projects would require substantial financial commitment from governments interested in science.
Marshall and Eicher discussed the potential for Elon to fund a large space telescope, estimating a cost of 2-3 billion dollars, which they noted would be manageable for Elon given his resources.Our guest emphasized the revolutionary impact such a telescope could have on understanding dark matter, dark energy, and the composition of the universe. The discussion also touched on the evolving role of citizen science and astronomy, with Eicher noting how amateur contributions have become more valuable and integrated into professional research over the past few decades. Dr. Kothari commented on the public excitement generated by the recent Artemis launch and expressed hope that this interest would help drive astronomy engagement among students.
Next, we focused on how space exploration and astronomy interest has evolved over time. David Eicher shared that while the Apollo program in the 1960s and 1970s significantly increased public interest in astronomy, modern space programs like Artemis are likely to generate similar interest. The conversation then shifted to challenges in astrophotography, particularly the impact of satellite trails on images, with David explaining that while software can remove these trails from amateur photos, it doesn’t solve the problem for professional astronomers who need accurate data. The discussion concluded with concerns about asteroid detection and planetary defense, with David noting that while no civilization-threatening asteroids are currently known to be in near-Earth space, it’s only a matter of time before another major impact occurs.
We also discussed asteroid detection and planetary defense, noting that while large civilization-threatening asteroids are well-cataloged, smaller city-killer asteroids pose a detection challenge. They explored potential defense mechanisms, including nuclear detonation to nudge threatening objects, though time constraints could be a significant obstacle. John Jossy mentioned Eric Schmidt’s funding of a space telescope that would rival Hubble, expected to begin operations in four years. The discussion concluded with our guest reflecting on how public reactions to comet sightings, like during the Hale-Bop phenomenon, often led to irrational fear and cult behavior, emphasizing the ongoing challenge of promoting rational thinking about astronomical phenomena.
Mr. Eicher discussed the prevalence of life in the universe, explaining that chemistry is uniform throughout the cosmos and that stars with planetary systems are common. He argued that the vast distances between stars make physical travel between solar systems extremely unlikely, citing the example that even the closest star system to Earth is four times more distant than the edge of our solar system on a scale where Earth-Sun distance equals 1 centimeter. When asked about the odds of discovering new propulsion methods that could minimize these distances, Eicher indicated the odds are very low, explaining that current physics laws, particularly relativity theory, make it impossible for mass to travel at significant fractions of the speed of light.
We discussed the odds of discovering extraterrestrial life, explaining that while the probability of encountering advanced civilizations physically is very low, the chances of detecting them through radio signals using SETI methods are significantly higher. John Hunt raised questions about dark energy, suggesting it might be driven by an inflation field rather than a constant, though Eicher noted that the scientific community still lacks a definitive answer. Ajay asked about progress in identifying terms in the Drake Equation versus addressing the Fermi Paradox, with Eicher explaining that SETI research is in its early stages due to the technical challenges of detecting signals over vast distances.
The discussion focused on the Drake Equation and its application to the Milky Way galaxy, with Eicher noting that while astronomers are finding more planetary systems, they haven’t yet detected Earth-sized planets and the equation’s accuracy remains uncertain. The conversation then shifted to space colonization, where Eicher explained that while building space stations and colonies like those depicted in science fiction is technically possible, it would require significant resources and time, and is not likely to happen soon. The discussion concluded with Bill raising questions about SETI and narrowcasting technology, acknowledging that while narrowcasting makes detection more challenging, the search for extraterrestrial intelligence remains a complex problem despite recent technological advances.
Eicher expressed skepticism about AI replacing humans entirely, noting that AI’s capabilities are limited by the quality of information fed into it. The group discussed active SETI, with Eicher suggesting that humans have already been broadcasting signals since radio and TV days, and emphasizing the vast distances involved in space travel. John Hunt contributed insights about the physical requirements for advanced life forms to develop technology, while Bill mentioned Project Hail Mary’s treatment of alien life in fiction.
As the program drew to a close, Eicher discussed human expansion beyond Earth, emphasizing the challenges and risks involved, particularly regarding Mars missions due to extreme temperatures and radiation exposure. He expressed support for space exploration, citing potential resource benefits and the long-term survival of humanity on Earth. Eicher also shared updates on his current projects, including his involvement with the Starmus Festival and writing for astronomy publications. The discussion touched on the limitations of relativistic dynamics in achieving high velocities and the importance of distinguishing science fiction from real science.

Hotel Mars, April 1, 2026, Space Show Broadcast 4524
NASA’s Artemis 2 Mission and the New Lunar Frontier kicks off with a successful Artemis 2 launch to orbit the Moon and return successfully to Earth. Our guests, Douglas Messier, details the upcoming Artemis 2 mission which will be the first crewed flight to the moon since 1972 plus as it swings around the moon, the orbit it uses will take it further from Earth than any other crewed spaceflight ever. . The 10-day mission will test the Orion spacecraft’s life support and technical systems, space suits, comms and much more. It is important to note that there is an international competition for a Permanent Base on the Moon by either the US or China. NASA plans to establish a permanent lunar base by 2036 but beating China for humans on the Moon as we plan on a landing in 2028. Landing by 2028 relies on the SpaceX and Blue Origin commercial lun landers, still under construction, with planned landings at the lunar the South Pole.
