北京时间2月21日11时26分,美国海军从“伊利湖”号导弹巡洋舰上发射了1枚“标准”-3导弹,成功击中了运行至太平洋上空的“美国”-193号间谍卫星。卫星被拦截时轨道高度为208千米,运行速度为7.55千米/秒,正处于失控加速下坠阶段。美国海军的官员称,拦截取得了成功,大部分卫星残骸将在48小时之内坠入大气层烧毁,一些小型碎片则将在随后的40天内陆续坠入大气层。从美国实施拦截的时间分析,美国对这次反卫星行动准备已久。从2008年1月起,美国就不断渲染“失控卫星可能坠地”的消息,并强调其上搭载的455千克有毒燃料可能对地面造成污染,这显然是在为其导弹拦截行动作铺垫。从一定意义上说,这次反卫星是对中国2007年1月11日空间试验的一种“回应”。美国作为世界第一航天强国,不能在反卫星这个重要领域无所作为;而如果紧随中国实施反卫星行动,战略对抗的意味就太过明显,也不符合美国自己一再承诺的和平利用空间。因此,在中国进行试验的一年多之后,选择这样一颗“会污染地面”的失控卫星来打,一方面可以做出“迫不得己”的姿态,另一方面可以展示美国的强大反卫星技术,取得战略平衡。这不能不说是大国之间的一种微妙语言。
Beijing time at 21:26 on February 21, the United States Navy launched a “standard” - 3 missile from the “Lake Erie” missile cruiser and successfully hit the “United States ”-193 spy satellite. When the satellite was intercepted orbit height of 208 km, the operating speed of 7.55 km / s, is in the run-up to accelerate the falling stage. US Navy officials said the interception has been successful. Most of the satellite wreckage will fall into the atmosphere within 48 hours and some small fragments will fall into the atmosphere over the next 40 days. From the time analysis of the implementation of the interception in the United States, the United States has been preparing for this anti-satellite operation for a long time. As of January 2008, the United States has continuously rendered “that the uncontrollable satellites may fall to the ground” and stressed that the 455 kilograms of toxic fuels put on them could pollute the ground, apparently paving the way for the missile interdiction. In a sense, this anti-satellite is a “response” to China’s space experiment on January 11, 2007. The United States, as the world’s No. 1 aerospace powerhouse, can not afford to do anything in this important area of anti-satellite operation. If its anti-satellite operation is followed by China, the tactic of strategic confrontation is too obvious and it is not in keeping with the United States’ repeated promises of peaceful space. Therefore, after more than a year of testing in China, choosing such a “uncontaminated satellite that can pollute the ground” can not only make a gesture of "compelling one another but also show the United States The strong anti-satellite technology, a strategic balance. This can not but be described as a subtle language between big powers.
