Its been a while since I found any cool toys on the web, but this NASA Java app made my day. It’s a 3D real time capable satellite tracking program. You can see a live updating display of over 500 satellites orbiting the earth. Pretty crowded up there really, from the right distance out the earth just seems to be covered with a cloud of dots. As I wrote this, COSMOS 1263 R/B flew just about right overhead and then on to Canada. Even though I’ve got no use for it other than the “ohmygoodnessthat’sreallycool factor”, I still think it’s really great that NASA has all that data out there on the web.
