This is good news for the USA, but it's GREAT news for countries where the government regularly cuts off and controls the Internet for political purposes. If receivers can be as small as a personal laptop, expect a thriving black market in them in places like Iran and Egypt. Such receivers can also act as backhaul for mesh networks, providing access to un-censored information in times of turmoil and peace alike.

I'd say it's more of problematic than great news for places with state controlled study. But it has potential. Where it's Great news is places which already can use only satellite internet, but have very poor experience. Rural Australia for example. Having low local (or even global) latency would be amazing.

25ms is pretty close to my broadband latency across Australia(Brisbane to Sydney).

Seven years. US Broadband providers have seven years to take us over the coals, practice full bore capitalism with our data and generally run oligilistic practices until their time even begins to run out

Why does capitalism always get bashed by people who don't know what it is?

I'm pretty sure NSA will want a backdoor in the system. If it can do what they say it can do, they are basically the new pipes of the Internet. It's too good for NSA and our current US govt to leave untouched.

Earlier quoted context omitted.

My understanding is that all new satellites have plans for deorbiting when they reach the end of their lifespan.

That's the plan - but when you have thousands or tens of thousands of satellites malfunctions can happen. Also, lots of existing space debris orbiting the earth that can hit satellites

These low orbits aren't stable though, I think they only have a lifetime of 10-20 years before their lateral velocity decays and they de-orbit on their own, it's not like will just be stuck up there.

No, with orbit altitudes of 1,110km to 1,325km we're talking about many hundreds of years: https://www.nasa.gov/news/debris_faq.html - "Debris left in orbits below 370 miles (600 km) normally fall back to Earth within several years. At altitudes of 500 miles (800 km), the time for orbital decay is often measured in decades. Above 620 miles (1,000 km), orbital debris normally will continue circling Earth for a century or more. "

They bash it exactly because they don't understand it and they listen to whatever they read on Facebook that tells them why it is evil. Basic Economics education outside of University and even within University is strongly lacking in this country. We need mandatory personal finance/macro economics courses as part of high school.

If it's difficult and/or expensive, it's not a real alternative, isn't it?

I'm using 3G or 4G as a cheaper alternative to landline broadband. It's… acceptable, but not amazing. 20 GB per month doesn't go as far as it used to before I started watching so many YouTube videos, even though I use 144p whenever possible.

You should check out T-Mobile. They have free video streaming if you enable it, but it forcibly downgrades the video streams to no higher than 720p. That still sounds like much better than you have however.

It's been said before, but what people need to understand is that the goal of this service isn't to make money- it's to balance demand. SpaceX can plan to launch be 30% more launches than their actual customers need. All those extra rockets are used for internet satellites. If there's an accident (boom) or a sudden need for more rockets, the internet satellites get delayed, and the paying customer gets a rocket. If c…

Wrong. The goal is to make money. Billions of dollars.

That money is to help fund Mars colonization, which has been SpaceX's ultimate goal from the beginning. There's also some nice synergy in that similar tech can be used to deploy a global communications network for Mars as well.

Well seeing as any future business in either rockets or satellite internet both depend on not creating space junk, I think they are pretty motivated to not let that happen.

Humanity is not so good at doing things in their best interests. We have over utilized any natural resource we have ever consumed often to our own determent.

Exactly. Evolution has not primed us with reward mechanisms linked to long term goals relating to pollution or over-utilisation of natural resources. Also financial incentives are often misaligned with these long term goals. As a result we have a tendency to create a mess - on land, in the oceans, in space, wherever we spread

They are transmitters and receivers. It would be like putting a "kill me" beacon on your house if the government opposed it.
