There is a plan to prevent such a strike—the Space Surveillance Network, a bevy of sensors that the military uses to track space debris. NASA monitors what’s unofficially known as the “pizza box,” a sort of no-fly zone around the ISS. When pieces of debris are predicted to enter the box—if there’s at least a 1 in 100,000 chance of collision—mission controllers order avoidance maneuvers, firing thrusters that move the ISS and dodge the trash. The technique has been used dozens of times since the first ISS module launched in 1998. But the system only tracks about 45,000 larger pieces, and all sensors have noise. Plus, risk thresholds can miss stuff, sometimes badly. In 2025, Chinese astronauts were briefly stranded at their station after debris hit their return vehicle.

为了还清生态账,宜昌将化工企业“关、改、搬、转”,对长江沿岸进行生态修复。与此同时,宜昌牢记“通过立规矩,倒逼产业转型升级”的嘱托,搞活了经济,冲破了财政收入下降、支出增多、就业压力增加等困境。“十四五”时期,宜昌地区生产总值增长预计6.5%左右,精细化工占比提升到47.8%,长江干流宜昌段水质稳定达到地表水Ⅱ类标准。
