Webtools: Do you know where your satellite is?

With all this talk about long-distance space explorations to Mars and yonder, it's easy to forget how much crap is up there already. Sebastian Stoff has created this little application to enable budding astrologers, Trekkies and other space fans to keep track of the many satellites circling the Earth. Orbitron is free, but it is "cardware," which means that if you found the program useful, the author politely requests that you send him a postcard. <http://www.stoff.pl/index.php>
