Solar Storms Cause Starlink Satellites to Fall From Orbit
The sun goes through cycles of activity, and right now, it's very active.
This activity, like giant explosions called solar flares, is affecting satellites orbiting Earth.
SpaceX's Starlink satellites, which provide internet, are being pushed closer to Earth by the sun's energy.
This causes them to fall faster than expected, and some even fall back into the atmosphere.
Scientists are studying this to understand how the sun's activity impacts technology in space, and how to better protect it.
Think of it like a big push from the sun making it harder for things to stay in their orbit.
Increased solar activity is impacting Earth's satellites, particularly SpaceX's Starlink.
Geomagnetic storms caused by solar eruptions increase atmospheric drag, causing satellites to re-enter faster.
A NASA study analyzed 523 Starlink satellites that fell back to Earth between 2020 and 2024.
The solar cycle peaks with solar maximum, leading to sunspots, solar flares, and coronal mass ejections.
Starlink satellites provide global high-speed internet, but also pose challenges to astronomical observations.
