Thanks for that I had forgotten about the Blockstream satellite network. So lets assume everything else is gone would BTC really be able to run and produce new blocks with just that small satellite network?

As long as there are miner/pool and node connected to internet satellite, Bitcoin network will continue to run. But we'll experience network congestion due to decreased hashrate since not all miner/pool subscribe to internet satellite. Although realistically, most people would worry more about social and economic impact due to majority of internet structure is gone.
