到1989年底,美国有两颗新的侦察卫星被送入轨道,这两颗卫星将大量收集有关地球上军事目标的情报。同时,在美国政府对监督军备控制协议、精确定位军事目标及在地球任一边远地区进行战争的能力方面开创了一个新纪元。第一颗新卫星是由阿特兰蒂斯号航天飞机于1988年12月2日送入轨道的。它是全新型的用雷达拍摄高质量地球表面图象的监视卫星。卫星的名字起先称为“靛蓝”,后来被改称为“长曲棍球”。 By the end of 1989, two new reconnaissance satellites in the United States have been put into orbit, and the two satellites will gather a lot of intelligence about military targets on Earth. At the same time, the United States Government has set a new era in supervising arms control agreements, pinpointing military targets and the ability to wage wars in any remote area on the planet. The first new satellite was orbited by the Atlantis shuttle on December 2, 1988. It is a new type of surveillance satellite that takes high-quality images of the Earth’s surface with radar. The satellite’s name was first called Indigo and later was renamed Lacrosse.
