美国一颗高新实验间谍卫星失踪

  美国一颗用于测试多项新技术的间谍卫星据信已完全与地面失去联系。路透社3日援引美国防务部门的消息来源说,负责美国侦察卫星设计、制造和运行的国家侦察局认定,那颗名为“L-21”的实验间谍卫星已“失控”,最终将烧毁在地球大气层中。

  最终进入大气层并被烧毁

  “L-21”实验间谍卫星项目是一项保密工程。卫星造价高达数亿美元,由洛克希德-马丁公司设计制造,于2006年12月14日升空。但在进入距地面350公里的近地轨道后,卫星便与地面失去了联系。

  不愿透露姓名的国家侦察局官员说,在未来几十年中,“L-21”会慢慢脱离轨道,然后进入大气层并被烧毁,因此不会对地面人类造成危险。

  两名美国防务官员告诉路透社,“L-21”用于测试一些新技术,它的失踪使美国军方在这一领域损失惨重。

  这两名官员不愿透露“L-21”究竟要承担哪些技术测试,但他们指出,其他国家在卫星侦察领域的发展相当迅猛,新技术也层出不穷,尤其是在测试雷达领域。

  影响其他情报项目

  报道说,五角大楼将在未来4至5年内利用其他卫星继续测试“L-21”上的一些新技术。此外,国家侦察局打算建造一个航天器用于测试新技术,但这项工程要待资金充足后才能启动,可能需等上数年。

  最近,美国发射的侦察卫星屡屡出现问题。国家侦察局负责人唐纳德·科尔3日在参议院情报委员会上作证说,他建议终止两项耗资数十亿美元的情报项目,因为它们不太可能成功完成。

  科尔没有透露这两个项目的具体内容。一名知情官员认为,科尔所指项目分别是由 onclick="activateYQinl(this);return false;" href="http://www.iask.com/n?k=%B2%A8%D2%F4" target=_blank>波音公司承包的“未来幻想建筑计划”和由洛克希德-马丁公司承包的“Misty”卫星计划。杜鹃(新华社专稿)
