Critics take aim at broadband satellite constellations

SpaceX, Amazon and OneWeb say their satellite mega-constellations will make broadband internet goodness available to billions of people around the world who are unserved or underserved — but some say those promises have to be weighed against the potential perils.

These critics cite the risk of catastrophic satellite collisions, concerns about cybersecurity and worries about environmental and health impacts  — including impacts on astronomical observations and the beauties of the night sky.

Such concerns are likely to intensify as SpaceX and OneWeb add to their current fleets of satellites in low Earth orbit, and as Amazon gets set to deploy more than 3,200 satellites for its Project Kuiper broadband network. If all the plans laid out for those ventures come to pass, tens of thousands of satellites could be put into orbit over the next decade.

Early today, SpaceX sent its latest batch of 60 Starlink satellites into orbit, bringing the total number of satellites launched to 1,265.

The latest challenge to the mega-constellations was filed today with the Federal Communications Commission. A coalition of policy groups is calling on the FCC to put a 180-day hold on further approvals for broadband data satellite deployments, in order to conduct a more thoroughgoing assessment of the risks.
