US and Canadian readers, enter your zip code below, hit Go!, and you will find out what is going to fly over your area in the nights ahead. There are hundreds of satellites in Earth orbit; we cut through the confusion by narrowing the list to a half-dozen or so of the most interesting. At the moment we are monitoring spy satellite Lacrosse 3, the International Space Station, the Early Ammonia Servicer, and the Hubble Space Telescope. Feedback is welcomed.
