Illustration for article titled This is Stephen Colberts NASA Space Station Treadmill

The Stephen Colbert treadmill looks tiny, but there isn't a lot of space to go around up there on the ISS. How does this work?

Since there's very little gravity in space, is there an elastic strap to pull the guy down toward the treadmill to simulate gravity? Or is the guy just whirling his legs around like the Roadrunner? [Orlando Sentinel via TV Squad]
