As of 10:30 a.m. EDT on Sept. 23, 2011, the orbit of UARS was 100 miles by

105 miles (160 km by 170 km). Re-entry is expected late Friday, Sept. 23, or

early Saturday, Sept. 24, Eastern Daylight Time. Solar activity is no longer

the major factor in the satellite’s rate of descent. The satellite’s

orientation or configuration apparently has changed, and that is now slowing

its descent. There is a low probability any debris that survives re-entry

will land in the United States, but the possibility cannot be discounted

because of this changing rate of descent. It is still too early to predict

the time and location of re-entry with any certainty, but predictions will

become more refined in the next 12 to 18 hours.

还是一样，不会落美国~~

刚刚有看到日本发布说会在台湾或日本一带著陆(?)
