The Federal Communications Commission (FCC) has approved a plan for Starlink to nearly double its satellite network, adding 7,500 new satellites. This could provide faster internet access for millions of Americans, especially in rural areas. However, scientists have raised concerns about what this expansion might mean for space safety and the environment.
Astrophysicist Jonathan McDowell emphasizes the need for caution. He applauded the FCC for not giving Starlink an unrestricted number of satellites but stressed the environmental implications could be serious. With almost 15,000 satellites proposed by 2031, worries about collisions and space debris continue to grow.
Currently, around 40,000 objects are tracked in space. Among these, over 1.2 million smaller objects could cause significant damage. Professor Vishnu Reddy from the University of Arizona noted that the real threat comes from smaller debris, which isn’t easily monitored. In recent months, Starlink satellites alone have performed more than 144,000 maneuvers to avoid collisions, up drastically from earlier data.
FCC Chair Brendan Carr has called the approval “a game changer” for American broadband. While there’s optimism for improved connections, Starlink’s current service has struggled to meet the FCC’s definition of reliable broadband. Despite this, users in remote areas have found Starlink to be life-changing. For many, just setting up the dish provides immediate access to the internet.
Concerns are also growing about the environmental impact of satellite deorbiting. Once satellites reach the end of their lifespan, they burn up in the atmosphere. A 2024 study indicated that increased numbers of satellites could release large amounts of aluminum oxide nanoparticles. As these trends continue, the composition of our atmosphere could change significantly.
Another layer of risk comes from moving satellites to lower orbits. Experts warn that this heightens the vulnerability of satellites to solar storms, which can disrupt their operations and lead to serious outages. Starlink plans to lower some satellites, which could improve performance but also add risks.
Starlink is not alone in the satellite race. China has proposed launching an astonishing 200,000 new satellites, though analysts are skeptical about the feasibility of this undertaking. Meanwhile, Amazon’s Project Kuiper aims to deploy over 3,000 satellites to compete in the growing space broadband market.
While Starlink holds promise for improving connectivity, especially for underserved areas, the rapid increase in space traffic poses new challenges. As McDowell noted, this is more than just about one company; it’s about the crowded future of space travel and the balance between innovation and safety.
