Does the signal go through the entire earth? Does it curve and travel around the earth? How come the earth isn’t blocking out the signal? I just can’t wrap my head around it. Same thing with satelites that transmit our internet. There can’t be thousands of satelites in a perfect formation that covers every angle, so how does it work?
PRIMARILY interested in the first scenario, how does the ISS transfer signals to USA if the earth’s mass is between USA and the satelite?

You can bounce radio signals off of the magnetosphere in specific conditions, but that’s not what’s going on here. There’s just a network of satellites in place, so if you can’t make a direct connection, you can relay it through satellites. We also have antennas all over the Earth that are connected through the internet, but not quite enough for complete coverage.
