Starlink Satellites Fall Back To Earth Every Single Day - Here's What Happens To Them
BGR • • science
Key Points:
- Since 2019, SpaceX has launched over 10,000 Starlink satellites into low-Earth orbit, providing broadband internet to over a million users worldwide, with each satellite designed to operate for about five years before deorbiting.
- In 2026, around 435-445 Starlink satellites reentered Earth's atmosphere, typically burning up during descent, though some fragments can survive and reach the surface, as seen in a 2024 incident in Saskatchewan, Canada.
- SpaceX identified flaws in its reentry risk assessments after the Saskatchewan event, leading to design updates for newer satellites and improved calculations to better predict component heating during reentry.
- Other companies like Amazon Leo and Chinese operators are launching large satellite constellations, which will increase the frequency of satellite reentries, potentially raising the risk of debris reaching Earth despite most satellites burning up safely.
- Satellite reentries release particles such as aluminum oxide into the upper atmosphere, which may persist and impact the ozone layer, highlighting the need for further research on the environmental effects of increasing satellite constellations.
