第九報

Update #9
Fri, 23 Sep 2011 10:01:35 AM UTC+0800

As of 9:30 p.m. EDT Sept. 22, 2011, the orbit of UARS was 110 mi by 115 mi
(175 km by 185 km). Re-entry is possible sometime during the afternoon or
early evening of Sept. 23, Eastern Daylight Time. The satellite will not be
passing over North America during that time period. 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 hours.

預計在24日的早上到中午(+8時區)墜落

UARS預測將不會進入北美地區，但時間跟地點仍是未知數...
