A summary of how space weather affects spacecraft and satellites.

Single event effects (SEE) cause bit flips in memory, FPGAs, CPUs, ...

Increased spacecraft drag and orbital decay due to the thermal expansion of the Earth’s upper atmosphere during space weather storms.

Attitude control disruptions caused, e.g., by large storm-time magnetic field fluctuations can lead to loss of cmd & control.

And there are lot more satellites in LEO now than in 2003 😨
