Satellites live inside the space weather environment. Solar activity doesn't just create auroras — it directly impacts satellite orbits, electronics, power systems, and communications. Understanding these effects explains why operators watch solar forecasts as closely as launch windows.

During geomagnetic storms, UV and particle heating causes Earth's upper atmosphere to expand dramatically. Satellites in LEO suddenly experience much more drag.
Energetic particles from the solar wind and radiation belts can accumulate on or inside satellite components, creating dangerous voltage differentials.
Space weather disturbs the ionosphere, which every radio signal between ground and satellite must pass through.
These aren't hypotheticals — they're real losses from real space weather events. The industry designs for them, but extreme events still cause surprises.
Operators monitor solar activity for all four. Design margins, operational procedures, and real-time alerts exist for each — but extreme events still push beyond what's planned for.
