Starlink offers highspeed (actually, not marketing gibberish), low latency internet around the world at a price people can actually afford and without unreasonable datacaps. This is possible because they are mass producing phased array antennas, something that was out of reach of common affordability before Starlink.
Starlink is comparable to Iridium like dial-up internet is comparable to fiber. Just go to Iridium's website and try to figure out what they actually sell to anyone who doesn't have elite pockets.
You align the element order to what is actually being compared. Just pointing that out for any other non-native English speakers.
True, but Starlink isn't what made phased array antennas affordable. The affordability of phased array antennas is what made Starlink financially feasible.
When the Iridium constellations were launched in the 1990s, the commercial phased array antennas in use today had not yet been invented. When the second-generation satellites were designed in the 2010s, phase array antennas were not yet commercially available, and did not become commercially available until around the same time that the 2nd-gen satellites were launched.
SpaceX was willing to sink over 3 billion into phased array r&d to make it happen.
Also tech from Broadcom and ST Micro
Wait what? Where's your source for that? Because phased array antennas were used on lots of 4G networks and are one of the cornerstones of 5G.
There where some PAA in deployment when I was in college almost two decades ago.
You should check out the proposed pricing for Starlink's maritime and aviation offerings...
Marine is a $10K one-time fee plus $5K/month.
Aviation, $150K plus $25K/month.
I'm sure you can get starlink at sea for around $1k per month

I can't see any upsides to this venture.
Also, without starlink Ukraine has said they would have been defeated quite quickly. (Ie fighting without a gun).
There are many upsides.
I'm sorry-- what? Surely a totally global satellite network available in remote regions such as mountains and jungles would just be a force multiplier for these kinds of activities.

Please let us know when you've found some.
The simple fact it, it is superior in many ways for a huge number of application and just denying the is never work.
As for the 'visual pollution' its mostly just not true. For the waste majority of humans its invisible basically always outside of a few situations.
For most terrestrial telescopes it doesn't really matter much. Broad visual surveying telescopes take a slight hit but its not like they will be no longer working. Many of the issues SpaceX has addressed and made the problem way less impactful.
Some very sensitive radio telescopes are also slightly effect and having some regulation like we do on earth for electronic devices would make sense.
The idea that its some horrible thing just doesn't hold up. The benefits outweigh the cost by a gigantic amount. Starlink is used to give good internet to native Americans who life away from infrastructure. The worth of these things are far, far, far higher then the few 10s of millions we lose in observatory performance.
How is providing access to the internet not an awesome thing for society?
There are millions of people in my same situation for which this system is doing good.
Also airplanes and light from cities pollute the sky infinitely more than these satellites do.
Sorry, but this is a very first world, urban perspective. Please have a little empathy. I live in the US and have only one choice for internet from home and it is lousy. Starlink has been a dramatic change for us. This is the situation for many, many people in the US and around the world.
Starlink is absolutely offering something that is NOT available terrestrially.
There's people importing dishes to use in cities in non covered countries today because of the condition of local networks in cities and the per bit costs
Check the steam download stats for top ISP's. It might surprise you the performance Delta with alternatives.
Telcos are complaining about roll out and spectrum costs. Some of them couldn't survive the 4G transition
The market can prove me wrong! :)
> Aside from some people who might live in rural areas in large countries that are hard to cover georgraphically
> There is no need for StarLink generally.
You point out that there is a market for StarLink and then you say it isn't needed. I'm confused. At any rate, no point in arguing about it. If there is no need they will lose a lot of money. If there is a need, they will make a lot of money. Time will tell.
JP Aerospace was doing some cool things with Airships to Orbit.(I know that sounds impossible. Check their out-of-date web site for details.) https://www.jpaerospace.com/
Some of my students flew sub-orbital space probes with them.
