The Space Show Presents Melodie Yashar, Friday, 1-9-26Quick summaryOur discussion started with a focus on Melodie’s transition from architectural engineering to space architecture, particularly her work on 3D printing concepts for Mars habitats and her journey through various organizations including NASA and Icon. The discussion covered technical challenges and opportunities in space colonization, including the development of lunar and Martian habitats, autonomous systems, and robotic construction capabilities. The panel explored the broader implications of space exploration, including technological benefits for Earth industries and the importance of long-term projects in advancing space settlement goals.Detailed SummaryDavid and Melodie discussed Melodie’s transition from architectural engineering to space architecture, focusing on her work with 3D printing concepts for Mars habitats. Melodie explained that her interest in space architecture was sparked by the unique challenges and opportunities it presents, particularly in creating sustainable and habitable environments on other planets. She highlighted the importance of collaboration with engineers and researchers to develop innovative solutions for space habitation. Our Wisdom Team also touched on the potential for future publications and exhibitions related to Melodie’s ongoing research in space architecture.Melodie discussed the evolution of space architecture, highlighting how commercial development in low Earth orbit has increased interest in creating hospitality-focused spaces for tourists and citizen astronauts. She shared her journey into space architecture, including her involvement in a NASA Centennial Challenge for a 3D printed habitat on Mars and subsequent work with NASA and private aerospace companies. Melodie also described her role at NASA Ames, where she researched the relationship between astronauts and autonomous systems, and her transition to Icon, where she helped commercialize large-scale additive manufacturing for housing and lunar applications.Our guest discussed her background in spatial planning and environmental design, highlighting the challenges in developing 3D printed structures for space habitats. She explained that while there is research on spatial planning, many questions remain about additively manufactured structures, particularly for large-scale, pressurized habitats. Melodie also described a recent project for a Mars habitat concept, expected to be completed by 2075-2080, and emphasized the importance of developing technologies that can integrate with both hard shell structures and soft goods for both lunar and Martian missions.Melodie and David talked about the feasibility of space colonization, particularly focusing on Mars and the moon. Melodie expressed skepticism about Elon Musk’s timeline for sending humans to Mars, citing numerous unknowns and challenges. She emphasized the importance of publishing and sharing information to ensure the project’s continuity beyond the current team. Melodie also mentioned her research on robot-to-robot interaction for autonomous operations in space, highlighting the need for further development in this area.The Space Show Wisdom Team discussed the challenges and potential of 3D printing habitats on the Moon and Mars, focusing on material properties and testing protocols. Melodie highlighted the need for Mars sample return data to understand regolith properties, while Haym noted that lunar soil testing on Earth could streamline processes but would still face challenges like electrostatic charging on the Moon. The conversation touched on AI’s role in anticipating anomalies in 3D printed structures and the importance of sending small-scale tests to the Moon before launching a habitat-scale program. Melodie suggested that the technologies are ready for deployment, but a timeline for lunar construction was not explicitly stated.Our guest talked about plans for lunar construction, predicting infrastructure development within the next 5-10 years, and emphasized the need for multiple redundant construction systems, including hard shell structures and additively manufactured components. She expressed skepticism about the viability of orbital hotels in the near term, noting that sustained human presence on the Moon would require significant infrastructure development and resource processing capabilities. Melodie acknowledged being in contact with commercial space station companies but highlighted the challenges of transferring technology from low Earth orbit to lunar surface operations, including the need for regolith processing and resource utilization.Melodie discussed her research on 3D printing with Martian regolith, explaining that while her previous work at Icon assumed no Earth-bound materials, she is now exploring binders and additives for Mars construction, including geopolymers and sulfur concrete. She clarified that her team did not use Martian soil simulants but instead relied on existing research from rover data to analyze regolith composition for a hypothetical 11-meter diameter habitat. When asked about other research using Martian simulants, Melodie confirmed their existence but noted that current simulants may not accurately represent all Martian regions of interest for settlement.The group discussed the challenges and opportunities in space exploration, particularly focusing on commercial versus government projects. Melodie highlighted the rapid development in the commercial sector and expressed optimism about future progress in in-space construction and lunar habitats. Haym Benaroya emphasized the value of contributing to a long-term project, even if specific concepts may not be realized during one’s career. David posed a hypothetical question about using an unlimited budget to expedite work, with Melodie suggesting that increased funding could accelerate testing and development of large-scale additive manufacturing and pressurized habitats. The conversation concluded with a brief discussion about lava tube habitats, though no specific work on this topic by Melodie’s team was mentioned.The lava tube topic continued with an examination of the feasibility of living in lava tubes for deep space radiation protection, noting that while this is viable, traditional construction methods and pressurization remain challenges. They explored the difficulties of deploying construction equipment in lava tubes and considered large-scale space elevators as potential solutions. David emphasized the significant gap between current reality and the vision of space settlement, while Haym Benaroya highlighted the additional complexity of biology in space. Melodie shared her research on robotic construction in space, discussing the shift from single-task robots to humanoid robotics, though she expressed skepticism about their effectiveness in space environments due to radiation and regolith challenges.David and Haym Benaroya discussed the current limitations of robotics in construction, particularly on the Moon and Mars. They highlighted that while robots can perform simple tasks in controlled environments like manufacturing plants, replicating complex human movements for construction is still far from being achieved. David referenced a recent 60 Minutes segment on Boston Dynamics’ Atlas robot, which struggled with basic movements like a jumping jack, emphasizing the technological challenges ahead. Haym added that reliability and maintainability are crucial for space missions, noting that even advanced robots require constant maintenance and support systems. They concluded that while automation in space construction is a long-term goal, significant progress and adaptation of current technology are necessary before it becomes feasible.The panel discussed the value and feasibility of space exploration, with Melodie emphasizing that space technology benefits multiple industries on Earth, though the benefits may take decades to manifest. Haym Benaroya highlighted space as a positive mission attracting bright students and fostering economic growth through dual-use development. The group explored the potential for naming lunar or Martian structures after key figures, though Melodie noted differences in procurement mechanisms for space versus terrestrial architecture. John Jossy invited Melodie to speak at the National Space Society’s ISDC conference in June, and the panel discussed the formation and goals of Melodie’s company, Anara, which focuses on 3D printing and robotic construction in space.
