Well, isn't that important? Isn't lifting the world's billions out of poverty a good

ordinary cell phones, and there's one satellite dish serving a whole village would
work as well with far fewer satellites, I suspect. Systems like Starlink aren't
driven by the needs of the Third World, they're driven by the applications that can
be monetized.

My inclination is to reply as follows: get back to me when you hear about how I
can buy my very own OAO-3 equivalent for the price of a 32-inch Dob.
Painting the satellites black, while reducing reflections, has the issue of introducing
thermal issues, which are bad enough in the insulating vacuum of space. Perhaps the
satellites should be covered with retroreflectors instead, since sending the light back
to the Sun would not be a problem. Of course, by day, at least, the Earth is also a
bright object.
