The idea of using centrifugal force to create a sensation of gravity in space originated as early as 1903, but a group of space enthusiasts believes its time has come. Check out Gateway’s vision for the Von Braun Rotating Space Station.

It’s amazing to look back at the great minds of the past and marvel at their visions for the future.

Astronaut Scott Kelly wrote a harrowing account last year of just how much of a mess he was when he came back to Earth after a year aboard the ISS. It’s no joke, the body relies on gravity for everything from balance, circulation and vision to maintaining bone density and muscle mass. A year in space can just about wreck you.
