@sundogplanets Just spitballing here.
The satellites would be larger and more expensive. They'd still want thousands of them to create a worldwide network. Then we'd have thousands of larger satellites occasionally firing thrusters while crisscrossing the sky and interfering with ground-based observations.
Not sure.
A solution would be to stop doing this and to pay for ground-based relays. We can do that, too. We don't have a billionaire strung out on drugs funding it.
The places where ground-based coverage is impossible could be serviced by drones. They don't stay in the air as long, so there would be expense there, too, but no costly launch vehicle, so it's a short-term win, I think. But Elon can't monetize it all for himself, so I figure it won't happen.
