Title: Escape Velocity Space News – EVSN – Satellite Constellations and Early Warning Systems

Organization: Cosmoquest



According to satellite cataloger Jonathan McDowell, there are now 18 satellite constellations, like Starlink, being planned. These constellations will contain 543,811 satellites. 

This is a whole lot of missions to try and keep from colliding and all it takes is one particularly bad collision to transform the more than half-million objects from useful technologies to a shield of shrapnel that protects our universe from us by trapping us here. 

In our closer look today, we are going to look at early warning systems that are being developed, and how future – more highly mobile satellites, can both do good and create chaos. (This episode was originally released on YouTube July 29, 2023.)
