According to NASA’s financing and a study published in June in June, the satellite used for the Star Link’s Internet service can eliminate the Earth’s ozone layer. 2024.
When the star link satellites reach the end of their lives, they burn in the Earth’s atmosphere and surpass the small particles of aluminum oxide. They travel in the ozone layer, which absorbs harmful ultra -violet radiation. Researchers at the University of Southern California found that the oxide increased by eight times from 2016 to 2022.
All these are not due to the star link – the Internet provider did not launch its first satellite until May 2019 – but currently it is the largest raft so far. According to data collected by astronomer Jonathan McDele, a satellite launcologist, more than 7,750 out of about 10,000 active items in the orbit of the lower ground are from the starlink. According to Space.com, the company is currently allowed to launch 12,000 more satellites and has planned more than 42,000 in the future.
These satellites are designed to continue for almost five years. About 66 66 pounds of aluminum oxide nano -particle will issue a satellite of 550 pounds. The satellite of the star link has been heavy over time, the latest version of it weighs about 2, 2,760 pounds.
Aluminum will be mostly released 30 to 50 miles from the ground level, but will then go into the ozone layer, which will take about 30 years. We are already seeing these effects – the satellite burning in 2022 caused a 29.5 % increase in aluminum above the natural level – but researchers said it would just be even worse.
“This is primarily a concern for the launch of a large number of satellites in the future.” “We estimated more than 640 % annually than the natural level. Based on this projection, we are very upset.”
Researchers said that unlike other substances that eliminate ozone, aluminum oxide particles do not eat. They keep damaging the ozone layer until they naturally come to the lower altitude, which can take about 30 years.
If it is hoped that the star link scales, more than 8,000 satellite can burn in the environment every year. Researchers have set a prediction model to calculate the increasing number of satellites in the sky and found that aluminum amounts can increase by 360 metric tons – or 640 % from the natural level.
Star Link has developed the satellite of satellites in the sky
The most worrying thing about this new research is still an unnecessary area. The study states that “the restoration of satellites makes environmental effects currently poor.”
Satellite is launching in four years of starlink, it has a 40 % part of all satellite Sometimes Launched, and it plans to extend its fleet seven times. The main rival of the starlink, the Amazon project Cooper, plans to launch 3,232 satellite In the coming years
An article published in nature states that 100,000 satellites in the sky are “not only possible but it is quite likely.” It is almost completely due to private companies such as Space X, Amazon and One Web, which are launching a satellite to provide high -speed Internet.
According to the EPA, excessive UV radiation can weaken skin cancer, cataracts and immune systems, as well as reduce crop production and barriers in marine food chain.
Researchers say, “As the rental rate increases, it is very important to further discover the concerns raised in this study.”
The Star Link did not respond to the CNET request to comment.
