well in fact there are multiple sat trains over the northern hemisphere lol ( and some on the south), according to the online sat tracker. apparently those trains help mitigate peak hour bandwidth usage, but i dont know better. still, thats an abnormal sight to have.
Starlink: Over 3,000. Plans to increase to 12,000. Each of them must be replaced every 5 years. At the same time, SpaceX doesn't yet have any ideas on how to bring old satellites down to Earth.
WTF?! Starlink provides such a better service to justify the multiple satellite count difference? This is despite the fact that they have a short lifespan and often go out of their orbit and smash into space debris, increasing the amount of space debris. Huh...
