SpaceX says the Starlink satellite network will eventually provide fast and cheap internet access across the globe, especially in areas that are now underserved.

Initially, the company planned to launch a total of 12,000 satellites to make the mega-constellation, but it recently asked permission to deploy an additional 30,000 satellites.

In May, SpaceX launched its first fleet of 60 micro-satellites into orbit. But a few days after the launch, some scientists expressed concerns.

Alex Parker, an astronomer, highlighted on Twitter that there was a risk that the light pollution could block our view of the stars.

There were also concerns about Kessler syndrome, the theory that a vicious cycle of mounting space debris and the increased likelihood of satellite collisions could one day stop humans from accessing space for hundreds of years.
