NASA’s decommissioned Upper Atmosphere Research Satellite, out of gas and out of control, is not descending toward re-entry as rapidly as expected, officials say, likely delaying the satellite’s kamikaze plunge to Earth by a few hours, to late Friday or early Saturday.
Experts expect more than two dozen chunks of debris to survive re-entry and hit the ground in a 500-mile-long footprint somewhere along the satellite’s orbital track. But given the bus-size 6.3-ton’s satellite’s trajectory and the vast areas of ocean and sparsely populated areas UARS passes over, experts say it is unlikely any falling debris will result in injuries or significant property damage.
Additional radar tracking is required to pinpoint when–and where–the satellite will make its final descent.
