I saw a line of the "starlink satellites" a few nights ago. Didn't know what it was until someone else explained it. Where exactly were they coming from? What is "launching" them? Hundreds have been reported worldwide. Is this part of the global system that will initiate a global Emergency Broadcast? If there were so many satellites deployed would that make an emergency broadcast imminent?
Bueller? Anyone?

Yep. Elon Musk has been launching Starlink rockets almost weekly. Each with 60 satellites onboard, releasing them in Low Earth Orbit. Check out starlink.com and youtube Starlink internet. Its very cool 😎
