that's not how it works. the blockstream satellite still requires internet to connect to the bitcoin network. however, you as the individual user of this centralized service don't need any internet. otherwise all the nodes, the miners, pools,... need the internet to communicate with each other.
believe it or not, there is no communication medium yet created that can replace internet. everything else is either short range, heavily centralized or inefficient.

I think we’re taking the expectations way too far here. Unless I’m wrong, this blockstream satellite project is the same one that Andreas Antonopoulos talks about here: https://www.youtube.com/watch?v=C1GxxlqRkKQ

The video is eight minutes long, so it’s easy to watch, and the first 2 minutes give you the basics.

Esentially, the satellites used are existing commercial satellites, on which a specific bandwith (/frequencies) is leased in order to transmit updated blocks and TXs. There are no nodes there, so, as far as I’m aware of, they only relay information in one direction, and a case use is that of avoiding censorship or gaining privacy as per the above video stated.

To receive BTC blockchain you need to invest at least 150$ to acquire a satellite dish,
change the Transceiver on the dish , and use a specific software based radio receiver. If I’ve read it right, it’s certainly not bidirectional, and in no way does it support global internet failure for Bitcoin TXs, as it does not have nodes of it’s own (nor are they expected to be there really).

I certainly doubt that the internet connection was down entirely in recent times. Please check the correctness of this news. If the internet goes down around the world, it's a braking news but fortunately I couldn't find anything that can support OP's claim! There was no shutdown at all at the global level, some local area can be affected but no news is found for that either! Seems like a FUD that OP couldn't catch!

Blockstream satellite communication is functioning in a single direction, you can obtain the data broadcasted by the system only. And as someone mentioned it works with commercial satellite, the same used for TV relay.

Actually we may think about SMS (?). International communications still rely on communications satellites like Inmarsat and Euteltracs.
We could send an SMS going to a satellite, if the internet connection goes down worldwide it won't be a problem anymore.
 Or even the phone network with copper

That is something I learned new today.
I mean, Though, it sounds great to hear that bitcoins have its own satellite for the users to be able to transact money whenever and wherever they want but it’s pretty unless. If the transaction was done using only the Satellite then it would be ok but the Satellite needs internet connection as well. So, using the Satellite will increase the cost nothing else.

It's a nice idea. My only problem with things like that is centralization. We could rely too much on the satellites and forget to create something decentralized and hard to censors.
 People should by now be brainstorming on how to create a decentralized global internet network. There are few viable "flying things" that can be used for this.

This is a very nice idea but bitcoin's progression through the years are slowing down perhaps there is a huge entity that will make this come true to life. But wouldn't it not be that risky for the crypto space? I mean if these satellites are shutting then it could also happen if there is a crypto satellite. On top of that problem, who would be in charge of doing that? take note that this is decentralized.

Thank you to clarify it, I thought Using satellite may cause additional costs and it needs internet connections for making transections.
If it broadcasts the Bitcoin blockchain for free and if the transaction can be done without internet connection then it seems useful cause till now internet connection is rare and expensive in many parts of the world.

So, there is a small set up cost when running a full node via Blockstream Satellite, as you obviously need a satellite dish and a low-noise block downconverter (the bit that sticks out in front of the satellite dish on a little arm), as well the necessary cables to connect your satellite receiver to your computer, but you can also repurpose an old TV dish or similar. Once it is set up, however, it is free to receive blockchain data from the satellite network.

Internet connectivity is still needed at some point to transmit a transaction, though. You cannot send a transaction directly back up to the satellites. If you don't have an internet connection, then there are other systems that I mentioned before such as goTenna, which will essentially transmit your transaction through a local network of devices until it reaches one with an internet connection, at which point it can be broadcast to the bitcoin network. From there it will be propagated in the normal way.
