Eruptions from the sun are shortening the lives of satellites in Earth orbit, particularly large constellations like SpaceX’s Starlink – which could be both beneficial and a cause for concern.
The sun goes through an 11-year cycle of activity, peaking with a period known as solar maximum, which most recently occurred in late 2024. During these periods, increased eruptions from the sun can create geomagnetic storms that heat our planet’s atmosphere, causing it to swell outwards in size and increasing drag on satellites.
