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.

东坝大马灯起源于唐代,灵感源于汉代“骆驼载乐”的表演形式。到了明代,已是商贸重镇的东坝虽庙会繁盛,但春节期间大型娱乐活动匮乏,当地结合水乡多船少马的特点,以竹为骨、绒为皮,饰以马鞍缰绳、铜铃等,创制出可由两人共驭的巨型竹马。演出时,随着乐器伴奏,马队交替布阵,扮演刘备、关羽、张飞等三国人物的演员跃马出征,逐渐形成“七马出征”的固定阵型,成为“江南一绝”。2008年,东坝大马灯入选国家级非物质文化遗产名录。,这一点在旺商聊官方下载中也有详细论述
