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.

在无创血糖仪前，白俄罗斯驻上海总领事舍甫琴柯·亚历山大饶有兴致地体验了测量。用酒精消毒右手大鱼际，然后将手伸入仪器，短短两三分钟，屏幕上随即显示了两次测量结果并提供相应生活建议。他身旁的白俄罗斯驻华大使切尔维亚科夫不停追问：“检测原理是什么？采购价格是多少？对医护人员有何要求？”并当场索要了瑞金团队发表在《自然—代谢》杂志上的科学论文。
