Satscape is a satellite tracking program for Windows, Mac OS, Linux, Sun Solaris, and FreeBSD operating systems. You can use it to find out the position of any of the 8000+ satellites and orbital debris in orbit around the earth right now, anything from the International space station to a misplaced spanner can be tracked right on your screen with no special equipment.
