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. 還是一樣,不會落美國~~ 剛剛有看到日本發布說會在台灣或日本一帶著陸(?) -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.37.94.228 ※ 編輯: physbook 來自: 114.37.94.228 (09/23 23:03) |
