This amazing site will bring you right to the NASA site that will tell you exactly when the International Space Station will be flying overhead. The space station is the THIRD brightest object in the sky (you better know what the other two are...wait for it...the Sun and the Moon!)
Obviously there needs to be a clear sky, and a clear night is the best, but any clear morning or late afternoon, and you'll be able to Spot The Station
Interesting facts about the Space Station
The international Space Station's length and width is about the size of a football field
It was launched on October 31, 2000
It weighs almost a million pounds on Earth, but is virtually weightless in space.
The Space Station has more livable room than a conventional five-bedroom house, and has two bathrooms, a gymnasium and a 360-degree ay window.
The electrical system alone has more than eight miles of wires, and the solar panels cover over an acre!
