This can make the atmosphere expand, causing UARS to fall to Earth faster than expected.
这可以使大气层扩大,导致高层大气研究卫星(UARS)比预期更快地下降到地球。
Since Earth is mostly water and sparsely populated land, chances are UARS won't cause any harm.
由于地球表面大多是水或是人口稀少,UARS有可能不会造成伤害。
They are trying to determine the satellite UARS returns to the atmosphere of the exact time and place.
他们正在试图确定这颗高层大气研究卫星返回大气层的准确时间和地点。
But debris falls from space all the time, and big objects the size of UARS come down about once a year.
但是一直会有碎片从太空落下,并且每年将会有一个大小同uars接近的大物体落下。
NASA's Upper Atmosphere Research Satellite, or UARS, is expected to reenter the atmosphere at the end of September.
美国国家航空和宇宙航行局的高层大气研究卫星,简称UARS,预计将于九月末返回大气层。
