A dead 6.5 ton NASA UARS satellite would make its re-entry into Earth's atmosphere on Friday, Sept. 23, bringing along a chance to watch a spectacular sky show. But NASA is still not sure where on Earth the satellite would land.
"It is still too early to predict the time and location of re-entry with any more certainty, but predictions will become more refined in the next 24 to 48 hours," National Aeronautics and Space Administration (NASA) said in a statement.
NASA added that the debris from the defunct satellite would not cause harm to humans.
NASA conducted a detailed re-entry risk assessment for UARS in 2002 and it showed that the debris from UARS is not harmful to human beings. Following are the excerpts of the study:
* Number of potentially hazardous objects expected to survive: 26
* Total mass of objects expected to survive: 532 kg
* Estimated human casualty risk (updated to 2011): About 1 in 3200
