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.
产品端聚焦用户痛点的创新的与精准的市场卡位，成为其破局关键。在电动两轮车赛道，九号避开雅迪、爱玛主导的中低端价格战，聚焦 4000 元以上高端智能市场，以无钥匙解锁、APP 控车等智能化功能切中年轻用户需求；割草机器人赛道则以 2499 美元的定价，对标欧美品牌 4000 美元 + 的价格带，凭借 “开箱即用” 的 RTK + 视觉技术快速抢占高端市场。渠道层面，依托 Segway 全球 30 多个国家的 3000 多个分销网点，其新业务可跳过冷启动阶段直接落地海外，而国内 80% 门店集中在二线以上城市的布局，也跑通了高租金区域的盈利模型 —— 一线城市单店年毛利达 42 万元，显著高于雅迪、爱玛的 33 万元和 32 万元。
