Planetary Analogs examines how architectural and environmental test sites model planetary conditions through hybrid infrastructures of experimentation. From Antarctic research stations and simulations in the Atacama Desert to underwater habitats and lunar prototypes, these sites are hyper-connected yet deliberately isolated laboratories that render the extraplanetary experimentally knowable. Developed under conditions of controlled dis:connectivity, planetary analogs translate global networks of science, technology and governance into insulated proxy worlds where the limits of habitability are rehearsed and redesigned. By tracing their emergence from Cold War geopolitics to the architectures of the New Space Age, the project is asking how such sites reframe globalisation’s Earth-bound logics to envision futures on — and beyond — the planet.
