Video- NASA satellite Defunct and falling back to Earth

NASA said on Monday that it expects a defunct science satellite to re-enter Earth's atmosphere on Friday. The 6.5-ton satellite, called the Upper Atmosphere Research Satellite (UARS), completed its mission in 2005 and has since been slowly falling back to Earth due to gravity.

The Upper Atmosphere Research Satellite, or UARS, has been inoperative for almost six years. Reuters reports that UARS was put in orbit during a space shuttle mission in 1991, and it collected measurements of ozone and other chemicals in the atmosphere for the next 14 years. Since 2005, it has slowly been losing altitude due to Earth's gravity.

However the Defunct NASA satellite won't land in PHL, PAGASA says:

"Huwag po tayong mangamba sapagkat ito po ay ginagarantiyahan ng NASA na hindi po ito makakaapekto sa tao," Raymundo said. "Maaari [lamang] po itong makaapekto sa mga astronaut, kung saan ay gumagawa sila ng mga extra-vehicular activity."
