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.

随着企业数字化转型深入，Data + AI 一体化成为技术架构的核心方向。传统数据湖主要管理结构化与半结构化数据（如 Parquet、JSON），如今正向全模态统一治理演进，将图片、音频、视频等非结构化文件纳入湖仓体系，实现“一湖多源”统一存储与管理。同时，计算引擎从单一大数据工具扩展至支持 AI 场景 Spark、Ray 等分布式框架，推动开发平台向一站式、智能化发展。
expensive as well, and still, in general, an unproven technology. Besides, the
