中国对卫星下手，美日准备开展保卫工作

In May 2013 the Chinese governmentconducted what it called a science space mission from the Xichang SatelliteLaunch Center in southwest China. Half a world away, Brian Weeden, a formerU.S. Air Force officer, wasn’t buying it. The liftoff took place at night andemployed a powerful rocket as well as a truck-based launch vehicle—all quiteunusual for a science project, he says.
在2013年5月，中国政府在西南部的西昌卫星发射中心开展了一项科学空间任务。但在半个地球以外的前美国空军官员布莱恩维顿并不买账。发射时间选在晚上，使用的是强大推力的火箭，而且发射装置是卡车式的——在他看来，对于一个科学项目来说，这显得异乎寻常。

In a subsequent report for the Secure World Foundation, the space policy thinktank where he works, Weeden concluded that the Chinese launch was more likely atest of a mobile rocket booster for an antisatellite (ASAT) weapon that couldreach targets in geostationary orbit about 22,236 miles above the equator.That's the stomping grounds of expensive U.S. spacecraft that monitorbattlefield movements, detect heat from the early stages of missile launches,and help orchestrate drone fleets. "This is the stuff the U.S. really cares about",Weeden says.
接下来，他给安全世界基金会（一个空间政策智库，也是他的工作所在地）写了一份报告，他总结道中国的这次发射更像是对用于发射反卫星武器的移动火箭助推器的测试。反卫星武器可摧毁赤道上空22236英里高的地球静止轨道上的目标。而正是在这个轨道上美国部署着昂贵的航天器，这些航天器监视着战场的活动，探测导弹发射初期所释放出的热量，以及用以协调无人机行动。“所以这正是美国真正关切的东西，”他说。
