Story summary

NASA warns the South Atlantic Anomaly (SAA) increases risk to space technologies from high-energy solar particles.
The anomaly has drifted northwest and split into two lobes since 2020, complicating satellite safety.
NASA uses satellite data and simulations to improve predictions of geomagnetic conditions.
The SAA's evolution is unprecedented in the space age, with similar anomalies occurring 11 million years ago.
