Satellites: space pollution alert! towards: This article explores the topic in depth.
Nevertheless,
Satellites: space pollution alert! Moreover, towards:
[DIGITAL Business Africa] – Behind space launches, a perhaps specious development. Furthermore, Researchers from the University College of London are sounding the alarm against the mega-constellations of satellites placed in orbit. Furthermore, These rockets which take off towards space allow to put satellites in orbit. Additionally, Furthermore, This is a lapalissade (obvious thing). In addition, But the latent truth is that during these launching operations. Nevertheless, several toxic substances are released in the upper atmosphere where they stay much longer. Nevertheless,
These are carbon dioxide and soot. Furthermore, Nevertheless, The results of the study of these researchers indicate that the number of space launches has increased considerably in recent years. However, mainly because of the launch of satellites. Consequently, 259 rocket launches in 2024 against 223 in 2023. For example, According to the specialized site lenumerics.com, this represents more than 153,000 satellites: space pollution alert! towards tonnes of fuel. Moreover,
Researchers at the University College London believe that the impact would be multiplied by 500. According to these researchers, orbit is not the only danger. Satellites placed in orbit have a “very” limited lifespan. Then. they fall towards the earth and disintegrate into the atmosphere, generating even more soot, as well as other particles, especially metallic. These could cause chemical reactions. What make Eloise Marais, Professor of Electronic Chemistry and Air Quality, Department of Geography, University College of London.
« Rockets and satellites reject more pollutants in the atmosphere than ever before. We are in unknown territory, because human activity has never polluted so much the upper layers of the atmosphere. Without regulation, these emissions could have serious consequences on the earthly atmosphere ”he said.
Operators. number of satellites
When we talk about satellite fleet, the first name that comes to mind satellites: space pollution alert! towards is that of SpaceX. The operator is in a pole with more than 8,000 satellites for its Internet service by Satellite Starlink. In second place, we find Eutelsat Oneweb. The operator has more than 502 satellites in low orbit. Oneweb is also a constellation offering high speed internet access services by satellite.
Their pursuer is a great power. China has more than 369 satellites. While its United States has more than 306. Then follow several American companies and Russia. Planet Labs, and its more than 195 satellites, observes the earth and provides high resolution shots of the planet.
Planet Labs has more satellites than Russia with its more than 137 spacecraft. Finally. Spire Global and its constellation of more than 127 satellites also observe the land, Swarm Technologies (constellation of more than 84 satellites), a subsidiary of SpaceX (again!), Which offers low -cost data services ($ 5 per satellites: space pollution alert! towards month) for the Internet of Things.
Finally, the Iridium operator, which offers more than 75 satellites, an international telecommunications service. Kuiper from Amazon deployed until August 2025 102 satellites. The operator is expected to launch 3,236 satellites to provide high speed internet access to poorly served areas.
