中国日报网环球在线消息：韩国航天研究所1月4日确认，韩国首颗多功能卫星——“阿里郎1号”在太空中失踪。 韩国航天研究所当天表示，该研究所的地面装置2007年12月30日与“阿里郎1号”失去了联系。目前，专家仍无法与该卫星取得联系，也没有找到卫星失踪的确切原因。如果在一周内仍不能找回“阿里郎1号”的话，他们将会放弃寻找工作。 据韩国媒体援引航天研究所工作人员的话称，专家一开始的鉴定表明，可能是卫星上某个机器失灵影响了发动机的正常运转，才导致其脱离轨道。 韩国于1999年12月21日发射了“阿里郎1号”，该卫星配有高清晰度电子光学摄像机，用于收集地球表面图象。据韩国航天研究所说，“阿里郎1号”从发射至今已经绕地球飞行了42985圈，向地面传回了44万张图像。阿里郎1号预计寿命本应到2002年，但是卫星燃料的消耗状态仍可以继续使用几年时间。 (欧叶) S.

It has orbited the globe 42,985 times and taken 440,000photossince it was launched, the KARI said. Initial reviews pointed toward a possible machinery maln oramisalignment that may have affected power generation, SouthKorea"sYonhap News Agency quoted an official of the KARI assaying. If communication with the satellite is not restored within aweek,KARI will consult with outside experts to discuss measurestoformally declare the satellite lost, Yonhap said. Arirang 1 is expected to orbit the earth for some yearsbeforebeing dragged into the atmosphere, where it will burn up andbedestroyed.
