Long-term data from ESA's Swarm satellites reveal that the South Atlantic Anomaly, a weak spot in Earth's magnetic field, has expanded significantly since 2014, driven by complex processes in Earth's core, with implications for space safety and navigation.
The South Atlantic Anomaly, a weak spot in Earth's magnetic field over the South Atlantic, has expanded significantly over the past 11 years, as revealed by ESA's Swarm satellites. This region's weakening is linked to complex patterns at Earth's liquid core boundary, and it poses risks to space missions by exposing satellites to higher radiation levels. The study highlights ongoing changes in Earth's magnetic field, which is vital for protecting the planet from cosmic and solar radiation.
A recent study using ESA's Swarm satellites shows that the South Atlantic Anomaly, a weak spot in Earth's magnetic field, has expanded and weakened significantly over the past decade, potentially impacting satellite safety and navigation systems due to increased radiation exposure and magnetic pole shifts.
