Satellite mega-contellations

China and companies like SpaceX, OneWeb, and Amazon aim to launch thousands of satellites into lower Earth orbits to reduce the time it takes for a signal to travel from the satellite to the user.

But some space experts are concerned that satellite mega-constellations could create more space debris. A 2017 study found that the deployment of satellite mega-constellations into low Earth orbit could increase catastrophic collisions by 50 percent.
