Viewing International Space Station

As you might know that International Space Station is in its orbit 200 miles above the Earth with all its on board staff members; it revolves around the Earth since its inception in the year 2000. It can be viewed worldwide with our bare eyes like we see aeroplanes on the sky. But when does it passes over the sky on your place, so that you can view it? For this NASA offers the web users a website. One can register his location in this website with his e-mail address in five steps. Whenever the International Space Station (ISS) is about to cross over your sky, NASA sends alert mails to your email inbox or text messages to your mobile phone that you registered with it. The space station usually passes over from once or twice a week to once or twice a month. You are enabled thus to see the station fairly for a longer time over the clear sky, with this website's help --> Spot The Station!
