From Space.com:
A dead climate satellite that has been circling Earth for 20 years will make a fiery death plunge this week, with some pieces of the 6 1/2 ton spacecraft expected to reach the surface of the planet, NASA officials say. The bus-size Upper Atmosphere Research Satellite, or UARS, will likely plummet down to Earth sometime around Friday (Sept. 23), according to NASA's latest projections. There is a 1-in-3,200 chance that UARS debris could hit a person, though NASA considers that scenario extremely remote.
"Re-entry is expected Sept. 23, plus or minus a day," NASA officials wrote in an update posted Sunday (Sept. 18). That means that by Saturday (Sept. 24), the UARS satellite should slam into Earth's atmosphere and break apart.
