Have you ever wondered why you often see this example of the International Space Station (ISS) in promotion pieces for Wolfram|Alpha and the Wolfram|Alpha App? Aside from the example being visually interesting, the results highlight Wolfram|Alpha’s ability to make complex real-time computations.

Wolfram|Alpha provides some great real-time computations in many, many areas, including satellites.  So what is a satellite? There are many definitions, but here we use the term to describe any artificial object in orbit around Earth that has an official North American Aerospace Defense Command (NORAD) number. This means NORAD tracks it and has assigned an official catalog number to it. The code behind Wolfram|Alpha’s dynamic satellite computations is rather complex. More »
