I'm pretty sure this is going to be the case.  Over the next few years we'll launch many times more satellites than we have orbiting now.  A lot are designed to bring the internet to remote places.

My wife and I camped at Fort Flagler last week.  Just before 6:00 am on Thursday the 20th, we observed a string of lights, at very high altitude, traversing the sky from NW to SE.  We counted 20 lights, all evenly spaced, with a few to the side of the "train".  I talked to a park employee about it, and nothing was on the news.  Later that day, he said that his wife did some searching and found a report of a similar string of lights over Florida.

When we got home I did some searching and found out they were SpaceX Starlink communication satelites, Elon Musk's project.

So yeah, satellite communication is coming to the masses, eventually.

I expect weíll see the devices down here getting cheaper and more common too. There are still some people who donít have an Inreach satellite texter because of the cost. As the technology and the state of the art improve, the kind of function we can get today from an Inreach Mini will get cheaper and cheaper. Personally I think itís irresponsible to be solo far from a trailhead without an Inreach today even at the $350 price, but itíll only be more so once they cost $100.

It's not really what the hardware costs, it's the (recurring) fee to access satellite communications.

Right now there isn't a lot of competition, this is a niche sector of the overall economy.  SpaceX is launching communications satellites, their constellation will eventually have up to 42,000.  By the end of this year, Starlink will have 1,500 satellites in orbit;  there are only about 3,000 satellites now, total.  Amazon and OneWeb have similar long term plans.

Iridium is 66 active satellites.

and nighttime skies will be forever ruined. perhaps the last thing that wasn't blatantly disfigured by mankind.

sure hope there isn't a collision that fulfills kessler's syndrome.

I believe the goal is to eliminate the cell tower altogether. Give everyone everywhere the ability to communicate and access the internet. Astronomers should be using instruments in space anyway. The price of doing that should be plummeting.

Yeah, when I saw the parade of satellites and didn't know what it was, part of me was hoping it was a bunch of UFOs.  When I found what it was, and how many satellites would eventually be in orbit, I was really disappointed.

Lots happening up the Duckabush this month...things come in threes...one more needed.

About the satellites....here is what looks to be happening....it occurs at the 18 second mark:
Break through the satellites in leaving earth

Speaking of accidents in the Olympics, I wonder how Aaron Brengle is doing? The peeps running his GoFundMe haven't been updating.

The ones SpaceX has been sending up are especially reflective, so they look extra bright against the sky.  All in a line.

This! ^

I see no good use for these things. I couldn't care less about having internet in the wilderness. And I like looking at a dark night sky, now that's been taken away, and for no legitimately good reason....

But is everyday satellite communications from a mobile phone even practical on a mass scale?  Won't the uplink power requirements drain the phone's battery way too quickly?

Let alone that satellites have a big footprint and don't allow for frequency re-use the way it is done in terrestrial mobile networks.  Is there even the data capacity for mass use?

Ah, the tinfoil hat brigade is out in force, hating what they know nothing about. No more dark skies because of a few tiny dots? Hahahaha! Dumbest thing ever written. Our whole civilization has destroyed dark night skies a thousand times worse already, much of the light pollution serving no useful purpose.

Itís amazing to me that people complain from a standpoint of complete ignorance. They hate something even when they donít even know what it can do or what itís for.

sorry. the dumbest thing ever written normally comes after you hit 'submit'.

read and provide counterarguments.
