The 20- year - old Upper Atmospheric Research Satellite (UARS) dropped about 24 pieces of metal debris ( 碎片) over 800 km as it entered Earth's atmosphere on Saturday. Nasa data tracks its descent ( 下落) from above the Indian Ocean off the coast of Africa to the Pacific Ocean at degrees south latitude and degrees east longitude. New Zealand was the only major land mass on its re- entry path. Nasa says satellite debris scattered ( 撒落) over the south Pacific Ocean about as far away from large land masses as you can says the US Air Force calculated the satellite entered Earth's atmosphere generally above American pieces of it did not start hitting the water for another 480 kilometers to the northeast, southwest of Christmas believe the metal pieces fell over an 800 - kilometre span.

Some other nations around the world also were monitoring the satellite's descent in the last two hours and all the predictions were well within the range estimated by JSOC. ” UARS was launched aboard space shuttle Discovery in stopped using the satellite in 2005, after moving it into a lower orbit that cut its life short by 20 years. 文章大意: Nasa 地图准确预测了卫星碎片的坠落轨迹。 63. Which is the right re- entry path of the falling satellite? - NZ- PO - IO-
