From what I read another article, these satellites are beginning to reach their end-of-life. This means that more and more are beginning to fail, and without launching a whole new fleet of them soon, it will only be a short matter of time before they all fail.
This means an enormous amount of new space junk will now be in orbit contributing to the already massive amount of space junk that is a growing problem with no fix on the horizon (pun intended).
It’s benign. Just shy of 50 tons of random space debris burn up in the atmosphere a day from non-human sources. Four Star Link satellites weight just over a ton.
The earth is normally getting hit with roughly 200 satellites worth of material a day, and it’s not even noticable beyond the shooting stars.
An inherent characteristic of any satellite in low earth orbit is that they will burn up without maintenance. This is because there is significant drag on LEO satellites from a very, very thin atmospheric remnant. Anything in a LEO orbit will burn up eventually, without periodic boost from thrusters.
Earth’s gravity is pulling them in, even the ISS which is farther away has thrusters to correct itself from earths pull. While working they thrust themselves to stay in prbit. These are much closer and once they’re non-functioning they won’t be able to keep themselves from falling (“orbital decay”)
The satellite burning up on re-entry is part of what makes starlink such an expensive proposition. SpaceX can’t fix them, they can’t re-use solar panels or wiring harnesses. No part of the shell or shielding. It’s all just…gone.
SpaceX are launching 26-52 satellites at a time and have sustained 3 launches a week for most of the year.
The satellites are in a Low Earth Orbit, without constant thrust, atmospheric drag will force them to re enter earths atmosphere within a few months. This means they aren’t adding to junk in space.
Unlike Nasa, ULA, Arriannespace, RoscosMos, etc… SpaceX have always performed 2nd Stage Deorbit burns, so they aren’t adding to Space junk by launching either.
The Low Earth Orbit is to ensure low latency and the need for constant thrust means the satellites have a short life expectancy by design. That is why SpaceX fought to keep the satellites as cheap as possible (e.g. $250k)
First stage booster reuse and fairing reuse means the majority of the launch cost is the second stage ($15 million).
NASA is a waste of money itself, however $2,000,000 accounts for half of the budget of Space X. If each rocket launch is $67,000,000 and they do 50 a year that’s about 30 launches on the house.

Low earth orbit- they burn up on reentry when they destabilize
This was (probably) the biggest reason they pushed so hard to create a re-usable rocket system. That shit gets expensive to replace.
Does all the burned gases fall back to earth?
Is vaporizing metal and raining or trapping it in the atmosphere benign?

Becoming non-functional isn’t the same as destabilizing in their orbit. Can they be made to then destabilize and burn up?
They are low enough air resistance will pull them down and burn them up over the course of a few months if they don’t do station keeping

The whole lot is privately funded
It’s sustained by NASA. Our tax dollars.
I thought NASA only paid SpaceX to fund NASA’s launches, not SpaceX’s launches. And still a lot cheaper than NASA’s own programs.

This right here proves you are an idiot who doesn’t have any idea what he is talking about. Shut the hell up dude.
Reported for harassment
So we wase 60 million a launch on 5,000 satellites so far. I’m actually curious to what the math is if all of these fall down for losses.
