Every single one of those will come down in an uncontrolled reentry. That's a lot of metal in the atmosphere, and a lot of dice-rolling to see if any more pieces will make it to the ground.
SpaceX is truly awful.

Not to forget the pollution! Burning up in the athmosphere does not mean disappearing.

@sundogplanets When satellites reenter, they don't cleanly vaporize, they ablate, releasing aluminum oxide and other metallic compounds into the upper stratosphere. Research has found measurable concentrations of satellite-derived metals at altitudes where they didn't previously exist. The long-term effects on stratospheric chemistry, ozone dynamics, and potentially cloud formation are not well understood and critically, they're not being studied at anything close to the pace of deployment.

@drewtowler @sundogplanets I'm sympathetic with you. Makes sense from your personal viewpoint. I've two doubts.
Bad take: does it make sense to pollute the atmosphere at global scale to bring connectivity in rural areas, if we balance the improved quality of life of the few benefiting against literally the rest of mankind (to be specist)? An utilitarian and an individualist would have no doubts. I have a preference too but I don't think it's ok to abandon rural areas and minority conditions in general.
So, the second doubt:
how much would it cost to bring 5G equivalent connectivity even to remote places? Is it really more expensive than the satellite system? Even without accounting for the negative externalities? And accounting for them? and even if it were, wouldn't it be the only ethical choice (albeit expensive)?@joe_vinegar @sundogplanets First point, it's definitely not OK to abandon rural areas, in my view it's about time they were given special focus after so many years of neglect - so I *think* we agree on that one.
Second point, I have no idea, but when you live where I do, it would require a lot of helicopters to place a hell of a lot of towers. The hills and valleys here are more crinkled than used aluminium foil, and communities are tiny and isolated, sometimes with access only by horse. -

@sundogplanets I'd do it in a heartbeat but I'm a freelance writer and would have to pitch it to newspapers. Still, I'll consider it. I've seen the night sky up in the mountains 15 years ago and quite recently and it is such an awful contrast already.

@sundogplanets like throwing a boxful of knives and axes high in the air and hoping they don't hit you on the way back down. With the added joy of the pollutants liberated when many of them burn up on re-entry

@hundhamm@muenchen.social @sundogplanets@mastodon.social The WWW model is silly. I don't need 25ms access except during occasional calls, which can be handled terrestrially.
Further, I have storage and RAM. Realtime terrestrial broadcast was fine but if you're doing digital data from space "it might as well come from the moon," while cheeky, doesn't seem to be a problem.
In other words, it's ok if it takes seconds for my netflix video to start. Maybe even minutes if my expectations / cost were set that way. -

@sundogplanets not only that. It starts with the launch of the rocket:
Lots kerosine is burnt.
The second stage burns up in the atmosphere.
All that burns up in the atmosphere stays there for quite some time and influences the atmosphere. -

@sundogplanets would that also measurably reduce the efficiency of solar panels?

@sundogplanets It is not the metal elements that pose a problem when entering the atmosphere, but the lenses and laser elements that were supposed to provide communication via optical path are resistant to the temperatures generated during atmospheric entry.

The good thing about Starlink satellites is that they don't stay up there long.

@michael_w_busch @Becovich Starlink also has higher ambitions concerning internet speed or bandwidth. I think that also requires more satellites, no?
@skaphle @Becovich as @michael_w_busch writes, the problem is not necessarily bandwidth - satellites can provide a very high bandwidth - it is latency. Satellites in geostationary orbit, for instance, have a latency of 1/4 of a second. That’s why Musk’s satellites need to fly low. But that reduces the area they can cover.

@sikorski Do you have a reference for that? Would be extremely useful if you can share!

Once SpaceX causes Kessler Syndrome, making LEO unusable, that will put an end to their Starlink business model for a while. -
