SpaceX just asked permission to launch 4,425 satellites.

"The system will be able to provide broadband service at speeds of up to 1 Gbps per end user."

Wow! That would be cool if they can pull that off.

Sounds like a copy cat of the failed Google attempt at this a few years back.

Of course, SpaceX first will have to perfect their rockets, which have a history of destroying themselves and their payloads on launch.

A nice idea, but there are many financial and technical things to overcome. Never give up hope, though.

SpaceX is your bargain launcher. Cheap flights but you get what you pay for.

Hi Jim16, 

This interview has some interesting thoughts from our CEO Mark Dankberg on this subject: http://www.satellitetoday.com/telecom/2015/12/14/viasat-embarks-on-global-triple-satellite-network/  

(The article was written a little while ago, so some of the specifics might be slightly dated, but I think Mark's thoughts are still quite relevant.)

Basically, he says that ViaSat has thought about a Low Earth Orbit constellation similar to what SpaceX announced. But he also notes that a LEO network of thousands of weaker satellites would have a lot of wasted capacity, since most of the satellites would be sitting above empty water at any given time. 

LEO just has a different set of advantages and disadvantages compared to what we are doing in the immediate future, and we obviously think our approach is better for our current goals. But I think it's fair to say that a lot of companies are interested to see if someone can make a LEO constellation really work.

Another interesting article.  It seems more companies are going to these "constellations".

The low latency you could get with these is key. I’m onboard for whoever is first.

Didn’t ViaSat file to put up medium satellites too?
