Part exhibition, part festival, FUTURES presents nearly 32,000 square feet of new immersive site-specific art installations, interactives, working experiments, inventions, speculative designs, and “artifacts of the future,” as well as historic objects and discoveries from 23 of the Smithsonian’s museums, major initiatives, and research centers. Of the nearly 150 objects on view, several are making their public debut: an artificial intelligence (AI)-driven rover from Alphabet’s X that could transform agriculture; a Planetary Society space sail for deep space travel; a Loon internet balloon; the first full-scale Buckminster Fuller geodesic dome built in North America; the world’s first controlled thermonuclear fusion device; and more.
