I somehow hadn’t realized that the International Space Station was visible from Earth, but it is, particularly if you are at an angle to catch the sun’s reflection of its solar panels. NASA has a tool to help you figure out when the ISS or the shuttle will be overhead wherever you are – use the “Sighting Opportunities” pull-down menu on the left-hand side to select exactly the town you are in for a list of times and how long it will be visible over the next couple of weeks.
