CAPE CANAVERAL, Florida (Reuters) - El satelite UARS de seis toneladas traspaso la atmósfera el sabado en el Océano Pacífico y tal vez en tierra indico la agencia espacial NASA.

CAPE CANAVERAL, Florida (Reuters) - A six-ton NASA science satellite pierced the atmosphere over the Pacific Ocean and fell back to Earth, the U.S. space agency said on Saturday, but it was not yet known where the remains landed. NASA said its decommissioned Upper Atmosphere Research Satellite, which took an unpredictable course as it tumbled through the upper atmosphere, fell to Earth sometime between 11:23 p.m. EDT on Friday and 1:09 a.m. EDT on Saturday. "The precise re-entry time and location are not yet known with certainty," NASA said of the 20-year-old satellite. There were reports on Twitter of debris falling over Okotoks, a town south of Calgary in western Canada, most likely satellite remains.
