Astronomers track solar storms using drag on SpaceX's Starlink fleet

Researchers are monitoring the atmospheric drag experienced by SpaceX's more than 11,000 Starlink satellites to calculate a daily 'sink rate,' the altitude a typical satellite at 480 km would lose in one day without thruster corrections. In 2026 that figure has swung from 19.7 meters per day during quiet conditions to 127.6 meters per day during the year's largest geomagnetic storm in January.

Study maps US regions most at risk from a Carrington-level solar storm

A new study in AGU Advances models how a rare, extreme geomagnetic storm—similar in scale to the 1859 Carrington Event—would strain the modern US power grid. Researchers found the Northeast and Northern Plains, particularly higher-latitude areas, face the greatest risk of widespread grid failure, with total economic losses estimated at $1.5 to $2 billion per day.
