Are you getting up early this Saturday or Sunday morning (or staying up late)? Gaze into the heavens and you'll see the International Space Station (ISS) and space shuttle Endeavor orbiting the earth in close formation at 18,000 mph. Sky watchers say the two will be brighter than any star in the sky, and easy to see with the naked eye, even from light-polluted cities.
The spacecraft will be plainly visible in most of the 48 contiguous United States and southern Canada. The best views will be in the Chicago area, where there will be four opportunities to see them, including one flyby on Saturday morning at 5:53 Central Time where they'll be zipping along virtually overhead, traveling from one horizon to the other in four minutes. They'll look like a pair of unusually bright stars, quickly moving on a northwest to southeast trajectory, with the brighter ISS positioned behind Endeavor.
