While most of George’s sculptures were geometric and named after the shapes he used, he began creating a series of sculptures that he called Space Churns in the mid-1950s, just as the race to get to outer space was featured in the news. This one was made the year before Neil Armstrong’s first steps on the moon in 1969. The shapes and motion are inspired by our solar system, with Earth and other planets and objects orbiting the Sun at different speeds.
