SpaceX created a swarm of about a thousand satellites that is circulating about 340 miles overhead, and building the constellation has put SpaceX in a "deep chasm" of expenses, according to CEO Elon Musk. The constellation has also raised concerns about potential in-space collisions and the impact on astronomers' ability to study the night sky. But for some early customers of the $99-per-month Starlink service, the satellites are already improving how rural communities access the internet.
