What about debris from LEO collisions moving into higher orbits?

Higher orbits require higher velocities, which aren't going to be reached by collision debris.

Collisions can absolutely eject debris at a higher velocity than either of the initial impactors.

Private corporations owning more and more utility infrastructure really concerns me. Is there a world where nations band together and launch this as public infrastructure rather than private corporations lobbying a USA government agency for permission?

The traditional justification for the government to own utilities is because they are a natural monopoly (e.g., the sewers), not because they are utilities. We should celebrate when technological advances changing things that previously were natural monopolies into competitive markets, like satellite internet.

At the very least, this has to be be better than the terribly regulated private monopolies we see in the stagnant, captive-audience-holding cable internet industry.

At what point should we start worrying about Kessler Syndrome? > The Kessler syndrome (also called the Kessler effect,[1][2] collisional cascading or ablation cascade), proposed by the NASA scientist Donald J. Kessler in 1978, is a scenario in which the density of objects in low Earth orbit (LEO) is high enough that collisions between objects could cause a cascade in which each collision generates space debris that i…

One obvious solution is to put them in an orbit low enough that they'll fall back within a few years.

I've heard that at least with the SpaceX satellites, they have full plans for decommissioning with these satellites re-entering the atmosphere. I do agree that this is a real concern though, and we'd hope there's pretty careful consideration, considering the sheer number of satellites being launched. Still, space is big .. really big, even the space just above our planet. I don't put it past humanity to not fuck up s…

It's not just that they have plans to do so, they're low enough that they'll de-orbit fairly quickly on their own without active control (boost from their ion engines). Something pretty strange would have to happen for them not to eventually burn up.

"just for some stupid trading" is one of the underlying forces beneath the success of all modern economies. Without it almost everything you buy would be more expensive.

Are you considering “having cheaper stuff” actually progress in terms of humanity ?

Yes, the march of human progress can be measured in the decrease in prices of all of the things we produce.

I'm more worried about the future sudden need to stop supporting the existing internet once a few companies decide we should just use their new space internet, that seemsnlike the more profitable longterm play.

It’s the same internet, just like when we switched from dialup to broadband.

> Get specific about the concern, otherwise it's easy to get afraid about everything. There are many reasons to be afraid about a private corporation from a country with little regulation providing a utility to areas with no other choice. If Amazon was sponsoring this, that's one thing, but them owning the network raises red flags for me surrounding: 1) Privacy 2) The potential for anti competitive practices 3) Quali…

Same thing happened in the UK with BT. Usual privatise the profits, socialise the costs.

This is false. When BT was privatized, the UK government sold the shares and collected the proceeds. That’s not “socializing the costs” any more than in any other divestiture transaction.

Additionally, these companies went from requiring huge operating subsidies to becoming net contributors to the exchequer through paying taxes: https://www.cps.org.uk/research/the-performance-of-privatisa....

> When the Conservatives came to power in 1979, the major nationalised companies were receiving large sums of taxpayers’ money. NERA’s report reveals that in the year to March 1980, the 33 companies it examined were contributing nothing to the exchequer: in fact they absorbed a total of £483 million between them, including £1,199 million in loan finance. British Steel was one of the worst companies requiring £1,020 million in the financial year 1980/81 on a turnover of just under £3 billion (thereby earning itself a place in the Guinness Book of Records).

> This dismal state of affairs has been reversed. In 1987, the 33 companies examined by NERA contributed £8,374 million to the exchequer. Net contributions have continued at a high level in each of the last eight years.

With right lobbying strategy and targeting lawmakers during campaigns, I have no reason to believe that Amazon cannot influence enough heads in their favor. Are government entities such as FCC are the absolute gatekeepers that we expect them to be? I am highly skeptical. Look how FAA handled Boeing's 737 Max and we ended up with two crashes. A company of Amazon stature and resources can easily influence and overwhelm FCC into giving them green light. For Amazon this is a two fold win; Blue Origin will finally have a purpose, and further domination of Amazon in farthest corners of the world.

Welcome to the dystopian future where no human anywhere on Earth can look up and see an authentic sky, as their ancestors did. https://www.nytimes.com/2019/06/01/science/starlink-spacex-a...

SpaceX just happens to have a way to solve the problem it creat…

> where no human anywhere on Earth can look up and see an authentic sky, as their ancestors did. The past ~80 years of light pollution has already prevented this from happening.

That is true. People go as far as dial 911 the first time they see the Milky Way.
