Dune-Inspired Stillsuits Could Allow Astronauts to Recycle Their Urine Into Water
If history has taught us one thing, it is that science fiction often gives way to science fact. Consider the Star Trek communicator and the rise of flip phones in the late 1990s and early 2000s, or how 2001: A Space Odyssey predicted orbiting space stations and reusable space planes – like the International Space Station (ISS) and the Space Shuttle. And who can forget Jules Verne’s classic, From the Earth to the Moon, and how it anticipated that humans would one day walk on the Moon? Almost a century later, this dream would be realized with the Apollo Program.
