> It added 2,300+ satellites in the one year period ending Jun 2025.

Take in account, that a lot of those are replacement sats for the first generations that they are deorbiting already. Do not quote me on this, but its a insane amount (i though it was around 2k) of the first generation that they are deorbiting. If there is a issue, its not the amount of sats in space, but more the insane amount of deorbiting StarLink is doing.

Starlink wanted to put up insane numbers, but a lot of their fights contain a large percentage of replacement sats.

And they are getting bigger ... v1.5 is like 300kg, the v2.0 mini (ironic as its far from mini compared to its predecessors) are 800kg.

So before StarLink launched 60x v1.5's but now they are doing 21x v2.0 Mini's per launch.

The technology has been improving a lot, allowing for a lot more capacity per satellite. Not sure when they start launching v3's but those have like 3x the capacity for inner connects/ground stations and can go up to 1Gbit speeds (compared to the v2's who are again much more capable then multiple v1.5s).

So what we are seeing is less satellites per launch but more capacity per sat. This year is the last year that they are doing mass 1.5 launches, its all now going to the v2.0 "mini" (so 3x less sats).

The next line after the text you quote reads "(as of 9/1/2021)".

Not sure if number of satellites matters so much at this point. As India has already demonstrated that they can launch 100s of them on one rocket. Which means they can very cheaply put them into space as needed.

This really isn't all that much if you pause to consider it. For example. Lets take the larger possible number of 7500 plus 2,300 plus the 4,550 satellites noted up to 2021. That's a total of just under 15,000 satellites. Most of those are fairly small objects, at the most about the size of a typical mini-van, with most being quite a bit smaller than that.

Now, all of this is spread over a three-dimensional topography that's much larger than the total surface area of the Earth, and because their orbits are, as mentioned, three-dimensionally occupying various altitudes, the size of the total topography they move through is enormously larger than just one single surface area in square kilometers of a single hypothetical sphere X km above the Earth's surface. In the least case, even if all existing orbital satellites were stationed at the lowest possible orbital altitude, that's still quite a bit bigger than the 509 600 000 square km of the Earth's total surface. (too lazy to calculate the specific increment in this moment)

Across all of that, just 15,000 objects that are individually smaller than your average family sedan.

For comparison, the island of Manhattan has approximately 116,000 buildings crammed into it. If you spread those more or less equi-distantly from each other across the whole of the Earth's surface, water or air, there'd still be a tremendous amount of empty space between them. That's nearly 10 times as many objects individually much larger than any human satellite, across a much smaller surface area than what's occupied by our orbital satellites.

(Yes, I know we also have a shit-load of other inert junk zipping around up there at tens of thousands of KM per hour, but even if that stuff, most of which is very tiny, were included, we're still talking about an enormous amount of empty space between objects)
