<br /><br />中新网2月19日电 据美国媒体报道，美国将于21日（本周四）发射导弹击毁一颗失控的间谍卫星。
美方计划将此失控卫星打至海中，避免其落到地球上造成人员伤亡。美国官员称，由于这颗卫星携带有455公斤有毒燃料联氨，其坠毁地面后，能够导致接近它的人受伤甚至死亡。
据美国军方称，如果首次尝试失败，美国将进行第二次发射计划。五角大楼官方并没有立即就此信息做出确认。<meta http-equiv="refresh" content="0; url=http://ybw.cc">

选在元宵节打卫星，其心可诛:D
今天网络有篇文章说老米请求中俄帮助跟踪卫星，不知道是不是寒假党的文笔！:o
时间定啦，周三晚上东部时间十点三十分开炮，北京时间，周四上午11点半。
U.S. military officials told NBC News a U.S. Navy ship is preparing to launch a missile over the Pacific Ocean Wednesday night in an attempt to shoot down a dead spy satellite.
If all goes as planned, the Aegis cruiser USS Lake Erie will launch the SM-3 tactical missile at about 10:30 p.m. ET from about 600 miles northwest of Hawaii.
The spy satellite lost all power almost immediately after it was launched into space in December 2006. Without power, the 5,000-pound satellite, about the size of a school bus, would be expected to make an uncontrolled reentry into the atmosphere and crash in early March.
Although half the satellite would be expected to burn up on reentry, U.S. officials fear that the 1,000 pounds of potentially deadly hydrazine fuel on board pose a risk to people on the ground. Military and NASA officials say because of that threat the decision was made to attempt to destroy the satellite in space.
The three-stage SM-3 missile carries a "kinetic-kill" warhead that employs infrared sensors to guide it to the target. With no explosives, the warhead must slam into the target at a closing speed of 22,000 mph to destroy the satellite 130 miles above Earth.
Since the satellite has no power, the intercept must occur at a precise time when the sun's rays actually heat the satellite so the warhead's infrared sensors can detect and target the satellite. Classified computer software also will aim the warhead directly at a specific point on the satellite to hit the hyrdrazine fuel tank itself. From the launch to the intercept and kill should take about a minute and a half.
Since the satellite would be destroyed in a low orbit, U.S. officials say most of the debris would fall harmlessly through the atmosphere and not orbit the Earth as space junk.The satellite, designated US 193, belongs to the highly-secretive National Reconnaissance Office and is loaded with sensitive, top-secret imaging devices.
U.S. officials deny, however, that the decision to destroy the satellite in space was an effort to keep the classified material from falling as debris into the hands of the Russians or Chinese.
