The trick to identifying these satellites is knowing exactly when and where to look. Using NASA's Liftoff to Space Exploration web site, you can find out which satellites will be passing over your hometown.
All the lonely objects, where do they all come from?
Accessing J-Pass only requires a recent version of either Netscape Navigator or Microsoft's Internet Explorer. J-Pass gives satellite rise and set times for your location, and indicates the part of the satellite pass that will be visible. The chart even includes positions of visible planets and bright stars. Sky charts can be printed out to be used as an outdoor reference guide. For viewers without a Java ready browser, the Liftoff site also has a mailing list system. By subscribing to the list, viewers will be notified by e-mail of upcoming satellite passes.
