We live in magical times: you read in the news that our national space shuttle just floated away from the international space station, and just that sentence seems like it comes from the future, even now. Even after I've heard it 100 times. For a few goosebumps, if you're a space nerd like me, watch this tour of the space station. If you're short on time, the payoff comes at about 8:40, when you can see out the magnificent Millennium Falcon-like window a floating blue sphere.
