Earlier this year at TED, Bjarke Ingels presented Mars Science City, currently being developed in Dubai. The 1.9 million-square-foot domed structure will become the largest space simulation city ever constructed. Mars Science City will house a variety of program pieces for both researchers and visitors, including laboratories for the study of food, energy and water; landscapes for agricultural testing and food security studies; and a museum celebrating humanity’s greatest space achievements and educating visitors on the city’s research. Utilizing one of the techniques currently considered for Mars habitat construction, the walls of the museum will be 3D printed using sand from the Emirati desert.
