The latest volatility for Bitcoin follows the strikes by the U.S. on Saturday that killed Iran’s Supreme Leader Ali Khamenei, who had been in power for more than three and a half decades. Iran responded by firing missiles at Israel, and by attacking U.S. military bases in Kuwait, the United Arab Emirates, and Bahrain.
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.
