BSV Podcast 0164: SAGA Space Architects

Balerion Senior Associate Aidan Daoussis sits down with Sebastian Aristotelis, Co-founder & Lead Architect of SAGA Space Architects, to explore what it will actually take for humans to live beyond Earth. Sebastian discusses SAGA’s mission-driven approach to space architecture, its deployable and 3D-printed habitats, lessons from living for months in an Arctic analog habitat, and the overlooked challenges of privacy, hygiene, sleep, and human well-being in extreme environments. They also discuss SAGA’s work with ESA, rigid-panel deployable structures, the economics of lunar habitats, and Sebastian’s vision for permanent settlements on the Moon and Mars.00:00 – Sebastian’s path from architecture and science fiction to designing habitats for extreme environments and space03:30 – What space habitats actually look like and why every SAGA design starts from the mission requirements07:10 – SAGA’s built habitats, including the Rosenberg Habitat, Lunark, and ESA’s Artemis training habitat11:02 – Engineering for the Moon: temperature extremes, micrometeorites, radiation, pressurization, and regolith shielding13:27 – What it will take to put a SAGA habitat on the Moon and why transportation infrastructure remains the bottleneck16:31 – The unglamorous realities of space habitation: human waste, hygiene, air recycling, and odor control20:03 – SAGA’s customer base across space agencies, aerospace companies, research institutions, and Starlab21:32 – Human-centered space architecture: privacy, sleeping quarters, ergonomics, climate control, and limited volume24:20 – Rigid-panel deployable habitats and using architecture to improve astronaut well-being and productivity25:40 – Circadian lighting, astronaut sleep, and SAGA technology now being tested aboard the International Space Station27:55 – SAGA’s competitive advantage: speed, vertical integration, in-house manufacturing, and rapid iteration30:22 – Lessons from living in Lunark in Greenland and experiencing acute and long-term stress firsthand33:55 – How lunar habitation could evolve from temporary deployable shelters to permanent settlements built with local resources38:52 – Why Sebastian believes lunar habitats can be built far more cheaply with a focused, scrappy engineering approach40:53 – What it would mean for humanity to truly become a multi-planetary species43:13 – Sebastian’s ten-year prediction: SAGA’s first habitat on the Moon This is a public episode.
