NASA’s Upper Atmosphere Research Satellite, or UARS, is expected to reenter Earth’s atmosphere on September 23, plus or minus a day, almost six years after the end of a productive scientific life. Although the spacecraft will break into pieces during reentry, not all of it will burn up in the atmosphere. According to specialists, someof the satellite burned up in the atmosphere, and about three dozen pieces, a total weight of five hundred pounds, would fall to Earth.
As of September 18, 2011, the orbit of UARS was 133 mi by 149 mi (215 km by 240 km). UARS satellite is a scientific satellite with 6.5 tons,which launched into space in 1991 to monitor the upper atmospheric layers. Since 2005, it was in “sleep mode” that preceded its gradual decline and then fall to Earth.
