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.
It also recommended no screening for men with a family history of the disease, for the same reason - too many cancers would be overdiagnosed and overtreated.

德索托最终没能走上总理岗位，这个变化本身，反而比任何一次就任更有象征意义。一个国家在宣布任命、撤回任命、再任命的反复之间，暴露的不是个人命运，而是制度预期的脆弱。在这种环境下，无论请来的是德索托，还是任何一位“明星经济学家”，恐怕都很难单凭个人之力改变局面。
