At 16 orbits a day, the ISS is passing over the U.S. and and can be seen from cities across the country. NBC's Brian Williams reports.
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.
