Will Elon Musk’s Starlink satellites deplete ozone layer? The full report

The ozone layer may be depleted by internet satellite networks like Elon Musk's Starlink. According to researchers from the University of Southern California, the ozone layer may be harmed by the large amount of aluminum oxide gas that SpaceX's Starlink satellites emit into the atmosphere. Because it shields humans from the Sun's harmful UV radiation, which can cause skin cancer and hurt crops and food supply, the ozone layer is essential. As per the reports of NDTV, there are more than 8,000 internet satellites in low-Earth orbit.

New concerns about satellite impact
Co-author of the study and University of Southern California astronautics expert Joseph Wang expressed his concerns over the issue. He said that his group was one of the first to investigate the potential consequences of these discoveries, as reported by NDTV.


Impact of Internet Satellites
There is a five-year lifespan limit for internet satellites in low Earth orbit. At the moment, Starlink controls about 6,000 of the over 8,000 of these satellites in orbit. It is intended for these satellites to burn up in the atmosphere when their operational lives are over. Every year, more than 1,000 tons of aluminum oxide, more than in the natural levels, could be released by this procedure. The destructive reaction of aluminum oxide with chlorine can damage the ozone layer.

What do the researchers say?
As per the reports of NDTV, researchers, aluminum oxides are the primary waste produced when satellites burn up during reentry when their service lives are coming to an end. It is well known that these oxides activate chlorine, which causes the stratosphere's ozone layer to deplete. They also indicated that 30kg of aluminum oxide nanoparticles, which could remain in the atmosphere for decades, can be produced by smashing a standard 250 kg satellite.

The study additionally discovered that between 2016 and 2022, the atmospheric concentration of aluminum oxides rose by approximately eight times. The current plans to launch additional satellites could result in an even higher number.

Future satellite launch plans
SpaceX has permission to launch an additional 42,000 Starlink satellites, as per the reports of 'The Independent.' In the upcoming years, dozens of satellites will also be launched by tech companies like Amazon.

FAQs:

Why is the ozone layer important?
The ozone layer protects us from the Sun's harmful ultraviolet radiation, which can cause skin cancer and harm crops and food supplies.

How many internet satellites are currently in low-Earth orbit?
There are over 8,000 internet satellites in low-Earth orbit, with about 6,000 belonging to Starlink.
