NASA’s Upper Atmosphere Research Satellite (UARS) is expected to fall to earth by Friday. Much of the satellite will burn up during its blazing flight through the atmosphere, but large components will likely survive to impact land or water. Because of the satellite’s orbital path, northern Canada and southern South America are most at risk from any incoming debris.
