STORIE Mission to Study Geomagnetic Storms and Their Impact on Satellites and Power Grids
US · Published May 11, 2026
A new instrument, STORIE (Storm Time O+ Ring current Imaging Evolution), is set to launch to the International Space Station (ISS) to help scientists distinguish between geomagnetic storms powered by the Sun and those driven by Earth's atmosphere.
This distinction is critical as the two types of storms produce different magnetic disturbances, satellite drag profiles, and timelines for grid-damaging induced currents.
STORIE will analyze the composition of Earth's ring current, a torus of energetic ions and electrons trapped by the planet's magnetic field.

Why It's Important?

Geomagnetic storms can have significant impacts on satellites, power grids, and other infrastructure. Storms dominated by solar protons tend to decay faster, while those driven by terrestrial oxygen can cause deeper magnetic disturbances and prolonged stress on power transformers. This can lead to satellite drag, accelerated orbital decay, and potential power outages. Understanding the source of the storm is crucial for operators to make informed decisions, such as whether to safe-mode satellites or shed electrical loads. Without this knowledge, forecasting collision risks, reentry timing, and grid stability remains uncertain, posing risks to billions of dollars in infrastructure.
