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.
以中国式现代化全面推进强国建设、民族复兴伟业，是新时代新征程党和国家的中心任务。在党的二十届二中全会上，习近平总书记谆谆叮嘱：“新班子起来了，一定要注意啊，不要有大干快上的冲动，也就是不能不按规律办事，急功近利、急于出成绩。要把这种浮躁心理、急躁心态都压下来，扎扎实实、踏踏实实地搞现代化建设。”

The camera modules are the same as last year, but Samsung is aiming to supercharge them with upgrades elsewhere, such as ProScaler image upscaling and an MDNIe chip that's said to greatly improve color precision. There's also a video stabilization feature that tries to keep the horizon level while you're following a moving person or pet, which sounds useful for action shots. The new Object Aware Engine is said to better render skin tones and hair textures to make your selfies look better. Samsung has reworked some AI features too, such as making Now Brief and Auto Eraser compatible with more apps.
