EVSN - Satellite Constellations and Early Warning Systems

<p>According to satellite cataloger <strong>Jonathan McDowell</strong>, there are now 18 satellite constellations, like Starlink, being planned. These constellations will contain 543,811 satellites.<span class="Apple-converted-space"> </span></p> <p> </p> <p>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.<span class="Apple-converted-space"> </span></p> <p> </p> <p>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.
