NASA Ames Research Center's 1970s-era space settlement project shaped a vision of the future.

Via Artsy:

In 1975, scientists at NASA’s Ames Research Center in Mountain View, California, dreamt up ideas for habitats that could house human civilization in space. Rick Guidice was a freelance illustrator with a background in architecture when NASA tasked him with creating the artistic renderings.

While the diagrams Guidice referenced might have envisioned how humans could survive in outer space, his paintings depict a future where humans could thrive. Lush English gardens and glassy ponds fill the floating platforms of cylindrical space colonies. Spherical habitats are flanked by reflective surfaces that mimic sunlight. A cross-section of swirling structures reveal rich layers of agricultural farmland. This was NASA’s modernist fantasy of the future.
