At this time, it is uncertain wether ROSAT debris hit the surface or crashed into the Ocean. Launched in 1990, ROSAT spent the last 21 years and 4 months in orbit. During the Entry time frame, the satellite passed over the Indian Ocean and parts of Asia (Myanmar and China). USSTRATCOM predictions had estimated re-entry to occur after the perigee at ~2:00 UTC for a crash just south of Chongqing, China - the largest city in the world. If ROSAT actually hit land will be announced later when more data has been analyzed. http://tinyurl.com/6d8f22y http://www.nspo.org.tw/2011/tw/info/new_list2.shtml?id=000409&hid=PD78u4sQ4B http://www.spaceflight101.com/rosat-re-entry-information.html -- ※ 发信站: 批踢踢实业坊(ptt.cc) ◆ From: 140.112.252.177 |
