When I was a child, I used to read Ray Bradbury books like R is for Rocket and S is for Space, and I wondered what it would be like to look up and see spaceships streaking across the night sky.

Tonight, I stood with my family and watched the International Space Station move smoothly, purposefully across the early evening sky at over 17,500 miles per hour.  I pictured the Expedition 20 crew members as they went through their routines, putting another sunset behind them and preparing to welcome another sunrise in ninety minutes.

I love living in the future.
