NASA said early Saturday it was trying to confirm the crash-landing of the biggest piece of
USspace junk to fall in 30 years, which was over Canada, Africaand open ocean during the re-entry window.
space agency stressed there was a "very remote" risk to the public from the 26 fragments of the Upper Atmosphere Research Satellite (UARS) which were expected to survive the fiery re-entry into the atmosphere. US
The debris was expected to re-enter Earth's atmosphere between 11:45 pm Friday and 12:45 am Saturday (0345-0445 GMT Saturday), NASA said in its latest update.
"During that time period, the satellite was passing over
Canadaand Africa, as well as vast areas of the Pacific, Atlanticand Indian oceans. The risk to public safety was very remote," the agency added.
"NASA is working to confirm the re-entry location and time and will provide an update shortly."
The Center for Orbital and Reentry Debris Studies at the California-based Aerospace Corporation predicted the re-entry would occur at 0404 GMT Saturday, plus or minus three hours.
The two dozen parts that survive the re-entry may weigh as little as two pounds (one kilogram) or as much as 350 pounds (158 kilograms), NASA said, and the debris field is expected to span 500 miles (800 kilometers).
