There has long been a dream of building a massive rotating space station to call home, such as the one featured in “2001: A Space Odyssey,” but the challenges of construction are huge, not to mention the logistics of lifting such large quantities of steel and other materials into space. A rotating station would need to be at least hundreds of feet across to make artificial gravity practical The bigger the better. So engineers have proposed spinning up asteroids as a kind of ready-built station. We would need to dig out the interior, but this would give us materials we could use.
