[Starlink] Starlink "beam spread"

[tom at evslin.com]

Was beyond my competence. But, as a student of innovation, I'd guess that
lack of gravity is a hindrance to the customary way of etching; but, once
the usual way is ruled out, lack of gravity may become a constraint removed.

Hi Tom,

I wonder how etching would work with no gravity...
