NASA Warns of Global Threat from Unknown Earth Crust Anomaly
NASA warns about the South Atlantic Anomaly, a growing magnetic field weakness over South America and the Atlantic Ocean caused by deep Earth processes, which threatens space-based technology by exposing satellites to high-energy particles. The anomaly is expanding, splitting into two lobes, and evolving dynamically, prompting ongoing scientific monitoring and international cooperation to mitigate risks and better understand Earth's internal forces.
