This Friday in This Blog's History I bring back a post on looking for the International Space Station (ISS) in the sky. The ISS orbits the Earth every 93 minutes, so when it passes over your sky, it's only in the sky for a couple of minutes. You have to be out at the right time and know where you're looking to see it, but it can be very bright and easy to see. The ISS isn't giving off its own light. Instead, what you see is sunlight reflected toward the Earth. Read the original post for more info on finding the ISS in your sky.
