Satellites rarely get much attention, but they’re the hubs that keep our modern world connected.
Just how many satellites are orbiting around Earth? Who’s launching them? And, what exactly are they doing up there anyway? These are good questions. Let’s dig in.
Today’s visualization comes to us from Carey Spies, and while it is based on older data, it provides a useful breakdown of the types of satellites that orbit the Earth.
There are now nearly 1,500 satellites in orbit in 2017, and if SpaceX’s plans for a 4,425-satellite communications network come to fruition, our planet’s exosphere will become even more crowded.
What do satellites actually do?
Satellites are launched into space for a number of reasons.
They do everything from military reconnaissance to keeping our GPS systems working properly. The truly global scope of telecommunications wouldn’t be possible without our expansive network of orbiting satellites. For example, O3b Networks’ 12 satellites provide broadband internet service to emerging markets.
