The Space Show Presents Rick Fisher on Space, National Security, China, Asia, Tuesday, June 9, 2026.
The Space Show Presents Rick Fisher, Tuesday, June 9, 2026Quick SummaryThe 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 SummaryDavid 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.Special thanks to our sponsors:American Institute of Aeronautics and Astronautics, Helix Space in Luxembourg, Celestis Memorial Spaceflights, Astrox Corporation, Dr. Haym Benaroya of Rutgers University, The Space Settlement Progress Blog by John Jossy, The Atlantis Project, and Artless EntertainmentOur Toll Free Line for Live Broadcasts: 1-866-687-7223 (Not in service at this time)For real time program participation, email Dr. Space at: drspace@thespaceshow.com for instructions and access.The Space Show is a non-profit 501C3 through its parent, One Giant Leap Foundation, Inc.

Dr. Eligar Sadeh returns as the guest to The Space Show
Dr. Eligar Sadeh, Tuesday, May 5, 2026, #4535Quick summaryThe 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 SummaryEligar 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.Special thanks to our sponsors:American Institute of Aeronautics and Astronautics, Helix Space in Luxembourg, Celestis Memorial Spaceflights, Astrox Corporation, Dr. Haym Benaroya of Rutgers University, The Space Settlement Progress Blog by John Jossy, The Atlantis Project, and Artless EntertainmentWe use Zoom phone numbers for program participation.For real time program participation, email Dr. Space at: drspace@thespaceshow.com for instructions and access.The Space Show is a non-profit 501C3 through its parent, One Giant Leap Foundation, Inc.

The Space Show Presents the May 3, 2026 Open Lines Discussion
The Space Show Presents Open Lines Discussion Today, Sunday, 5-3-26Quick 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.

The Space Show Presents Shubber Ali, Founder of Space Cynics
The Space Show Presents Shubber Ali, Sunday, 4-19-26Quick 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 missionsThe 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.Special thanks to our sponsors:American Institute of Aeronautics and Astronautics, Helix Space in Luxembourg, Celestis Memorial Spaceflights, Astrox Corporation, Dr. Haym Benaroya of Rutgers University, The Space Settlement Progress Blog by John Jossy, The Atlantis Project, and Artless EntertainmentWe use Zoom phone numbers for program participation.For real time program participation, email Dr. Space at: drspace@thespaceshow.com for instructions and access.The Space Show is a non-profit 501C3 through its parent, One Giant Leap Foundation, Inc.

The Space Show Presents Bob Zimmerman, Tuesday, May 26, 2026
Bob Zimmerman, # 4594, May 26, 2026Quick 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.SummaryBob 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.Bob Zimmerman, # 4594, May 26, 2026Quick 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.

The Space Show Presents Paul Wardley on special thin film solar for space and more, Friday, 4-17-26
The Space Show Presents Paul Warley, CEO of Ascent Solar, Friday, 4-17-26Quick 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.Special thanks to our sponsors:American Institute of Aeronautics and Astronautics, Helix Space in Luxembourg, Celestis Memorial Spaceflights, Astrox Corporation, Dr. Haym Benaroya of Rutgers University, The Space Settlement Progress Blog by John Jossy, The Atlantis Project, and Artless EntertainmentWe use Zoom phone numbers for program participation.For real time program participation, email Dr. Space at: drspace@thespaceshow.com for instructions and access.The Space Show is a non-profit 501C3 through its parent, One Giant Leap Foundation, Inc.

The Space Show Presents A Starship Demo 12 Test Discussion
Detailed Summary:SpaceX Starship Launch DiscussionThe 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.Special thanks to our sponsors:American Institute of Aeronautics and Astronautics, Helix Space in Luxembourg, Celestis Memorial Spaceflights, Astrox Corporation, Dr. Haym Benaroya of Rutgers University, The Space Settlement Progress Blog by John Jossy, The Atlantis Project, and Artless EntertainmentWe use Zoom phone numbers for program participation.For real time program participation, email Dr. Space at: drspace@thespaceshow.com for instructions and access.The Space Show is a non-profit 501C3 through its parent, One Giant Leap Foundation, Inc.

The Space Show Presents Virtual Moon With Manny Pimenta, Philippe van Nedervelde
The Space Show Presents Virtual Moon With Manny Pimenta & Philippe van NederveldeQuick Summary:This was a Space Show program featuring Manny Pimenta and Philip van Nedervelde presenting their Virtual Moon project, which aims to create a digital twin of the lunar surface for immersive virtual reality experiences. Manny explained that Virtual Moon began as Lunar Explorer over 20 years ago but was ahead of its time when consumer VR hardware wasn’t available. The current project uses NASA’s Lunar Reconnaissance Orbiter data as its foundation and includes a working Apollo 11 landing simulation that can be experienced on VR headsets like Quest 2 and 3. Philip detailed their technical approach, which involves using AI and generative adversarial networks to upscale the LRO data to higher resolution and create photorealistic lunar terrain. The team demonstrated live reactions from users experiencing the VR simulation and discussed their plans for “One Giant Leap,” a new product release featuring multiple Apollo 11 mission vignettes including Armstrong’s first steps on the moon and the lunar module’s ascent. They also revealed their concept for “Selene City,” a large-scale lunar habitat designed to accommodate 5,000 people by 2045, which would serve as both an engineering simulation and potential resort destination. The discussion covered technical challenges including real-time rendering requirements and how they plan to address issues like unlit craters and lava tubes through lighting systems and future data upgrades.Detailed :SummaryThe meeting focused on demonstrating Virtual Moon, a virtual reality project that creates immersive lunar experiences. Manny introduced the project’s history, explaining that it evolved from Lunar Explorer, which was created over 20 years ago when consumer VR hardware wasn’t available. Philippe detailed the technical approach, describing how they use NASA’s Lunar Reconnaissance Orbiter data as a foundation and plan to enhance it using AI and generative adversarial networks to achieve higher resolution and accuracy comparable to Apollo mission photographs. The team encountered technical difficulties with screen sharing during the demonstration, preventing them from showing the actual VR content to the audience.Manny explained that Virtual Moon offers users the opportunity to own a piece of virtual lunar property, starting with 100 square meters free, with additional property available for purchase. He announced the upcoming release of the “One Giant Leap” Apollo 11 VR experience, priced at $15, with a $10 pre-order that includes 2,000 square meters of Virtual Moon property as a special promotion. Philippe clarified that the experience will be web-delivered and compatible with various VR headsets including Quest models and Pico headsets, with plans for a multi-user metaverse version of Virtual Moon.Philippe explained how the virtual moon mapping system will handle dark craters by using virtual headlights to illuminate elevation data, and mentioned that the system will be updatable with higher resolution data from other space agencies. He described a planned collaboration with a company developing an unmanned mission to explore lava tubes at Lacus Mortis, where robots equipped with lidar would provide real-time 3D scans that would be integrated into the virtual moon system. The team also discussed their existing Apollo 11 VR landing experience, which recreates the actual landing trajectory and maneuvers using historical telemetry data, and Dr. Kothari expressed interest in potentially using similar virtual mission simulations for his own lunar landing system designs.Manny and Philippe discussed plans for Virtual Moon, which will include a complete recreation of all moon missions with photorealistic 3D animations, serving both space enthusiasts and the professional space industry for mission planning and troubleshooting.
