Dr. Eligar Sadeh returns as the guest to The Space Show

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 t
