Why are satellites important?

The short answer

Satellites are important because they provide communication services to underserved and remote areas1. They can deliver high-speed broadband internet to billions of people who currently lack access2. Some companies aim to provide this global coverage as a greater good3. Beyond connectivity, satellites have commercial potential and can be used for artistic purposes2. However, large groups of satellites in low Earth orbit will significantly alter ground-based optical and infrared astronomy1. They may also change how people around the world see the night sky1.

What the evidence shows

Global Connectivity

SpaceX is launching a massive initiative to provide internet from space3. The Starlink satellites are intended to offer global coverage3.

Project Kuiper aims to provide high-speed, low-latency broadband to unserved communities2. These services are designed for remote and underserved areas1.

Commercial and Artistic Uses

There is significant commercial potential in the growth of satellite mega-constellations2. One group even proposed launching orbiting billboards to show advertisements to Earth2.

Satellites can also serve artistic purposes, such as the Humanity Star light beacon2.

Impact on Astronomy

Large groups of bright satellites in low Earth orbit will fundamentally alter ground-based optical and infrared astronomy1. These objects could impact the appearance of the night sky for stargazers worldwide1.

Our take

This part is our own interpretation, not a sourced finding.

The idea of orbiting billboards shows how commercial interests are moving into space2. It is surprising that these same satellites might change the way we study the stars1.

What we can't say for sure

It is not certain how much the night sky will change for stargazers1.
