Sven Grahn in Sweden has an amazingly interesting hobby. He’s a spy satellite tracker, born out of his desire to find out what really was going on in outer space during the Cold War. Other than tracking the satellites, Sven also records the radio signals that these spy machines, many not even having record of their existence, send back to earth. What appears to be white noise and random bleeps to some, is a symphony of cold war technology, outer space mystery and dreams to others (this coming from someone who’s other projects are all named after NASA space programs).
