The International Space Station orbits the earth 16 times a day.  But it just so happens that this week's orbit patterns bring it right over the top of some big U.S. population centers.  This week you'll see a bright light moving faster than any plane across the sky -- you'll just need to get to a dark place. As you watch, remember: the ISS is home to six people, travelling 17-thousand miles an hour, and they're more than 200 miles high.
