Amazon wants to put a “constellation” of 3,236 satellites in low Earth orbit as part of Project Kuiper, a project that aims to provide “low-latency, high-speed broadband connectivity” around the globe to “tens of millions of people who lack basic access to broadband internet.” According to the United Nations (UN), 4 billion people around the world currently either have no Internet access or are underserved.

The massive project will take years to realize and will cost billions, but the Amazon expects that it will eventually pay off and enable the company to rake in billions of dollars in revenue. However, Amazon will have to compete with other firms like SpaceX and OneWeb that are pursuing similar projects.
