...chafing to fund the system (see following story) and was heartened by the first test, in which an interceptor pulverized a fake warhead last October. In a second test in January, however, the interceptor missed its target by 241 ft. when a cooling line clogged and shut down its heat-seeking sensors. As a TIME investigation shows, little is being left to chance this time. So little, in fact, that this may be a test in name only--an expensive piece of Potemkin performance art to win enormous military appropriations. Exactly what is going to be tested on Friday...
...enemy could slip its warhead inside a decoy balloon and deploy it along with a dozen identical balloons, forcing the Pentagon into a futile effort to destroy all of them. The warhead might be cloaked in a shroud of liquid nitrogen, chilling it so that the interceptor's heat-seeking sensors couldn't find it. Chemical or biological weapons might be deployed in dozens of bomblets far too numerous to destroy...
Back in the sky over the Pacific on Friday, physics and chemistry will take over. The interceptor's three sensors--two detecting heat and one detecting visible light--all share the telescope that juts out its front end. The visible-light sensor will get the interceptor into the right neighborhood, but only the infrared sensors can guide it into its target, gently steering it with minithrusters powered by 30 lbs. of liquid rocket fuel. For the heat-detecting sensors to "see" anything, they must be chilled to -330[degrees]F using nitrogen and krypton, funneled to the sensors through...
...presidential election, when nobody's going to be in a hurry to make new military commitments abroad. The combination of draconian political laws and a hopelessly divided Serbian opposition has left Milosevic sufficiently confident to seek a fourth term in the fall. He's not exactly feeling the heat, but he could be turning it up come September...
...summer in New York City. Heat is emanating from every imaginable surface. I live in a very small apartment on the fifth floor of a walk-up building. I have an extremely feeble air conditioner that seems to be rendered impotent by temperatures above 80 degrees...
